1. Assessment Guidelines Prior to Placement
<ol>
	<li>Prior to insertion, assess rectal opening for contraindications which include: 
	lesions, tumors, abscesses, rectal bleeding, diarrhea&#160;or recent bowel surgery (less than 6 weeks).</li>
	<li>Assess rectum for stool by performing a digital rectal exam prior to placement. 
	NOTE: It is best if the rectum is empty, however, formed stool in the rectum is not a contraindication for use.</li>
</ol>
2. Insertion of the Device
<ol>
	<li>Lubricate catheter from the tip to the blue marker line with water-soluble lubricant.</li>
	<li>Insert the catheter into the rectum to the blue marker line between the two blue arrows.</li>
	<li>Inflate balloon with Luer syringe by injecting&#160;15 mL water or saline.</li>
	<li>Gently tug catheter to assure balloon is positioned against the rectal sphincter.</li>
	<li>Position catheter between the legs and secure to the anterior aspect of the patient&#39;s thigh or lower abdomen with a catheter-securing device.</li>
</ol>
3. Medication Preparation and Administration
<ol>
	<li>Pulverize solid forms of medications.</li>
	<li>Add 10 - 20 mL water to pulverized medication to produce a microenema suspension.</li>

The administration of medications and fluids via rectal mucosal absorption has been utilized in various environments over a long time period, with the provision of fluids by this route specifically given the term proctoclysis or rectoclysis6-9.&#160;Nevertheless, despite the effectiveness of this route, practical use has been limited by the availability of a convenient, and easy-to-use device to leverage it. The initial reports of use in the ED have shown that the catheter is easy to place, and the onset of effects from medications administered via the catheter appears quickly. Since the time to place the device is minimal, the catheter appears to be a valuable medications and fluids administration device in emergency and critical care settings.
Because the device is non-sterile, and is placed in the rectum in a similar fashion to a standard Foley catheter placed in the urethra, minimal skill is required, and almost no advanced training is necessary. The most critical component in rectal delivery of medication is an understanding of dosing via the rectal route. Most opiates, benzodiazepines, and NSAIDs are well absorbed and dosing is comparable to the oral route. An extensive review of the literature on rectal absorption of medications used in the palliative setting has been compiled15. It is important to note that hypotonic fluids should be used for proctoclysis, as absorption through the rectal mucosa occurs by passive diffusion and isotonic and hypertonic fluids may have a cathartic effect. With the use of hypotonic fluids, rectal hydration via infusing water at a rate of up to 400 mL/h&#160;has been demonstrated, with a mean rate of 224&#160;mL/h7.
Due to the simplicity of the device there is minimal need for troubleshooting. It is important to note that the medication port on the catheter mates only with an enteral syringe. Luer syringes cannot connect to the medication port. This feature was designed to avoid misconnection errors between parenteral devices (Luer syringe) and gastrointestinal device (enteral syringe). For this reason, an IV bag cannot be attached directly to the catheter for administration of fluids as IV tubing is fitted with Luer connectors. A &#34;Luer to Enteral&#34; adaptor can be purchased for this purpose, or hydration can be performed by bolusing the patient with fluids using a 60 mL enteral syringe that comes with the catheter in the kit supplied by the manufacturer.
Critical situations such as shock, sepsis or cardiac arrest need parenteral access either by IV or intraosseous methods, as rectal medication and fluid administration does not provide immediate absorption; however, a rectal catheter can provide an additional rapidly accessible route in these situations. For example, in the incidence of sepsis, when protocols demand large volumes of fluids in a short period of time, multiple IV access points are necessary, and rectal fluid delivery can be a way to increase vascular volume rapidly while multiple IVs are being implemented. In addition, the catheter can provide a route of access for medications that cannot be instilled intravenously, such as Buspirone for the control of shivering in hypothermia induction and aspirin for platelet inhibition and fever reduction.
Difficult IV access is an increasingly common problem in the ED setting. Fields et al. found that 1 in 10 patients admitted into an urban ED were considered to be &#39;difficult IV access&#39;16. For patients in whom vascular access is difficult, delayed&#160;or unnecessary, this new method of medication and fluid delivery may prove invaluable in the ED. Medications and fluids can be administered in minutes while awaiting ultrasound placement, central venous placement, or during repeated attempts at peripheral placement. In these cases, the rectal catheter can allow for hydration or management of a patient&#39;s condition that may be complicating IV access, by decreasing the difficulty of placement. In pediatric patients, who are well known to have difficult IV access (and generally fear invasive or painful procedures), this technique may be a good alternative.
Intraosseous infusion is painful and pre-medication with lidocaine can be time consuming. For alert patients that are not critically ill, the use of this catheter may be preferable from a cost, time, and patient comfort perspective, since the cost of the device offers significant savings over alternatives such as a popular intraosseous needle delivery system in widespread use. The catheter may be a good alternative to nasogastric placement for fluid and medication therapy since no imaging, such as X-ray confirmation of placement, is necessary and it less likely to cause discomfort or injury during placement. Even with ultrasound guidance technology, IV placement can be significantly delayed and treatment can be initiated and even completed without IV access offering additional savings in time and money. Significant savings can be realized in the use of lower cost oral medications (such as tablets that can be crushed and administered via the catheter) compared to intravenous formulations of the same medication. Finally, this device has less potential for complications compared to IV access, decreasing the incidence of infections, infiltration, and embolism associated with intravenous treatment.
Patient types that commonly present as difficult peripheral IV access and may benefit from this method include patients with diabetes, obesity, renal failure, edema, IV drug use&#160;or those receiving chemotherapy. Most pediatric and elderly patients may also benefit. Specific clinical needs for which the catheter may be used in the emergency setting may include hydration, fever, pain, agitation, seizures, migraine, sickle cell crisis, gastroparesis&#160;or nausea and vomiting.
The catheter can also be used for instillation of retention enemas such as lactulose for elevated ammonia, Kayexalate for elevated potassium, and saline or other preparations for severe constipation, or to assist for disimpaction. It is an alternative option for retention enemas than the currently utilized bowel management systems which employ a larger diameter shaft and balloon, and it is easier to insert and use.
There are several other benefits of using of the catheter in the ED setting, including decreased wait times, decreased staff burden, and decreased iatrogenic complications related to intravenous therapy. Patient satisfaction can be improved with reduced wait times, and patient symptoms such as pain or vomiting could be relieved quickly without having to wait for IV access.

The most common routes of administration for medications and fluids in the emergency care setting are generally oral (if the patient can tolerate oral intake), intravenous (for more rapid administration, or provision of medications not orally bioavailable), or intraosseous (in the case where intravascular access is difficult to obtain). Nevertheless, in many cases, patients who are too ill to tolerate oral intake are also dehydrated, with poor vascular access that prevents placement of intravascular (IV) lines. In most cases, intraosseous placement is not an ideal option, since the discomfort of administration in an awake patient can be significant.
A new device, the catheter, offers an alternative route via rectal mucosal absorption, which is a route long-known to be effective and easy to access1-11. Absorption through the rectal mucosa is generally rapid, with blood levels of many drugs attaining therapeutic levels rapidly, in part as a result of avoiding the first-pass effect.12 The catheter has a silicone tube that is 14 Fr in diameter and has a 15 mL balloon at the tip. The balloon provides for secure retention of the catheter for retention of administered medications and fluids, yet also allows elimination through passage via defecation. The catheter has multiple exit ports at the distal tip for fluid and medication passage, and an internal one-way check valve at the proximal end to prevent backflow of fluids (Figure 1). A description of the components of the device is shown in Table 1.
This catheter, which became available in 2014, was originally intended for palliative care and hospice patients, being designed to meet the needs of family members taking care of patients in the home setting, eliminating the need for hospitalizations and more invasive care. The product design particularly enables the preservation of the patient dignity while being easy enough for those without a medical background to use. However, because of its appeal for use with emergency department and critical care patients, the device has been increasingly utilized in this setting recently. In particular, case reports and case series describing the novelty of this approach in the emergency setting first appeared just in the last year13,14.
The features and benefits of the catheter enable easier and more efficient use of the rectal mucosal administration route than has been available previously. Placement of the catheter is easy, with no need for sterility. Use of the device requires no advanced training, since it is placed in a manner similar to a standard Foley catheter. Because placement is simple, repeat attempts at vascular access can be avoided, which increases satisfaction of both providers and patients. Indications for the device are to provide rectal access to administer liquids/medications.
Case Presentation
A number of examples of use of the catheter in emergency settings, including emergency departments and intensive care units, have been recently reported13-14. Examples of these include:
Case 1
An 80-year-old male with multiple medical comorbidities, including obesity, chronic leg wound, skin grafts, HTN, CAD, and COPD, presented to the Emergency Department (ED) via ambulance with fever, decreased mental status, and cough. Attempts at IV access by ambulance personnel, and subsequently by ED personnel after arrival, were unsuccessful. The patient&#39;s initial vital signs were:&#160;BP 124/68, HR&#160;98, T 38.4 &#176;C, O2 saturation of 92% on 2L NC, and GCS of 14 (due to confusion).
Case 2
A 41-year-old female presented via ambulance in alcohol withdrawal with vital signs of BP 110/78, HR 120, T 36.9 &#176;C, and oxygen saturation of 98% on room air. Her Clinical Institute Withdrawal Assessment of Alcohol (CIWA) score was 9. Attempts at obtaining IV access for administration of fluids and benzodiazepines were unsuccessful, and the patient was deemed too disoriented and agitated to safely tolerate oral administration.
Case 3
A 25-year-old female presented via ambulance with acute confusion, agitation, and tachycardia resulting from substance abuse, including cocaine and heroin. She had an underlying untreated hyperthyroidism for which the patient was previously taking methimazole. Her vital signs were BP 118/73, HR 117, T 37.4 &#176;C, and oxygen saturation of 97% on room air. IV access was established with some difficulty; however, the patient remained too confused and agitated to safely tolerate methimazole tablets (the medication is only available in oral form).
Case 4
A 59-year-old male was brought into the ED&#160;after a cardiac arrest followed by return of spontaneous circulation after defibrillation, but persistent coma. Therapeutic hypothermia was instituted, but despite maximum cooling power provided by external surface pads, the patient&#39;s temperature was noted to be climbing, likely as a consequence of ongoing shivering. Because an NG tube placed to suction revealed gastric contents to be similar in appearance to coffee grounds, GI bleeding was suspected, and NG tube administration of medications, including acetaminophen and buspirone was felt to be contraindicated.
Diagnosis, Assessment, and Plan
In all of the above patients, this method of medication delivery provided a useful alternative treatment modality to address challenging medication and fluid administration conditions.

a novel approach for the administration of medications and fluids in emergency scenarios and settings

The available routes of administration commonly used for medications and fluids in the acute care setting are generally limited to oral, intravenous, or intraosseous routes, but in many patients, particularly in the emergency or critical care settings, these routes are often unavailable or time-consuming to access. A novel device is now available that offers an easy route for administration of medications or fluids via rectal mucosal absorption (also referred to as proctoclysis in the case of fluid administration and subsequent absorption). Although originally intended for the palliative care market, the utility of this device in the emergency setting has recently been described. Specifically, reports of patients being treated for dehydration, alcohol withdrawal, vomiting, fever, myocardial infarction, hyperthyroidism, and cardiac arrest have shown success with administration of a wide variety of medications or fluids (including water, aspirin, lorazepam, ondansetron, acetaminophen, methimazole, and buspirone). Device placement is straightforward, and based on the observation of expected effects from the medication administrations, absorption is rapid. The rapidity of absorption kinetics are further demonstrated in a recent report of the measurement of phenobarbital pharmacokinetics. We describe here the placement and use of this device, and demonstrate methods of pharmacokinetic measurements of medications administered by this method.

Initial reports of the use of this method of medication and fluid delivery in the emergency or critical care setting demonstrate rapid effects from the medications and fluids administered in the variety of conditions described13,14.&#160;In addition, these patients tolerated the procedure well with no complaints of discomfort. The average time taken for placement of the catheter was about 1 min. Furthermore, the procedure was well accepted and the patients who were awake and alert verbalized satisfaction with this mode of fluids and medications delivery. The clinical outcomes for the four cases presented are shown below.
Clinical Outcomes
Case 1
The 80-year-old male with multiple medical comorbidities was provided a total of 50 mL of fluids and medications, including water, aspirin tablets dissolved in water, and acetaminophen (oral formulation), for the treatment of fever, dehydration, and elevated troponin. Approximately 90 min later, the patient was afebrile, alert, and oriented (Figure 2).
Case 2
The 41-year-old female in alcohol withdrawal and a Clinical Institute Withdrawal Assessment of Alcohol (CIWA) score of 9 was given 2 mg of lorazepam, resulting in immediate improvement of the patient&#39;s agitation, orientation, and tachycardia. The patient was then given 4 mg of ondansetron along with multiple aliquots of tap water at a rate of 10 mL every 2 -&#160;10 min over the subsequent hour, resolving her tachycardia and eliminating her nausea, while bringing her CIWA score to zero.
Case 3
The 25-year-old female with acute confusion, agitation, and tachycardia resulting from substance abuse (cocaine and heroin) with an underlying untreated hyperthyroidism, was given methimazole tablets after being crushed and suspended in water. The catheter remained in place in the Intensive Care unit (ICU) for subsequent administrations every six hours until the patient improved sufficiently to begin tolerating oral intake the day after admission.
Case 4
The 59-year-old cardiac arrest patient was given liquid acetaminophen (650 mg) and Buspirone (30 mg) via the catheter, which was then flushed with normal tap water. Shortly after the administration of these medications, the patient&#39;s previously rising core temperature effectively plateaued at 36.9 &#176;C and he clinically stopped shivering.

Vascular Occlusion Training for Inclusion Body Myositis: A Novel Therapeutic Approach

Inclusion body myositis (IBM) is a rare idiopathic inflammatory myopathy. It is known to produces remarkable muscle weakness and to greatly compromise function and quality of life. Moreover, clinical practice suggests that, unlike other inflammatory myopathies, the majority of IBM patients are not responsive to treatment with immunosuppressive or immunomodulatory drugs to counteract disease progression1. Additionally, conventional resistance training programs have been proven ineffective in restoring muscle function and muscle mass in these patients2,3. Nevertheless, we have recently observed that restricting muscle blood flow using tourniquet cuffs in association with moderate intensity resistance training in an IBM patient produced a significant gain in muscle mass and function, along with substantial benefits in quality of life4. Thus, a new non-pharmacological approach for IBM patients has been proposed. Herein, we describe the details of a proposed protocol for vascular occlusion associated with a resistance training program for this population.

The present article presents the details pertaining to the application of resistance training associated to vascular occlusion in IBM patients.

Use of a Central Venous Line for Fluids, Drugs and Nutrient Administration in a Mouse Model of Critical Illness

This protocol describes a centrally catheterized mouse model of prolonged critical illness. We combine the cecal ligation and puncture method to induce sepsis with the use of a central venous line for fluids, drugs and nutrient administration to mimic the human clinical setting. Critically ill patients require intensive medical support in order to survive. While the majority of patients will recover within a few days, about a quarter of the patients need prolonged intensive care and are at high risk of dying from non-resolving multiple organ failure. Furthermore, the prolonged phase of critical illness is hallmarked by profound muscle weakness, and endocrine and metabolic changes, of which the pathogenesis is currently incompletely understood. The most widely used animal model in critical care research is the cecal ligation and puncture model to induce sepsis. This is a very reproducible model, with acute inflammatory and hemodynamic changes similar to human sepsis, which is designed to study the acute phase of critical illness. However, this model is hallmarked by a high lethality, which is different from the clinical human situation, and is not developed to study the prolonged phase of critical illness. Therefore, we adapted the technique by placing a central venous catheter in the jugular vein allowing us to administer clinically relevant supportive care, to better mimic the human clinical situation of critical illness. This mouse model requires an extensive surgical procedure and daily intensive care of the animals, but it results in a relevant model of the acute and prolonged phase of critical illness.

Bedside Ultrasound for Guiding Fluid Removal in Patients with Pulmonary Edema: The Reverse-FALLS Protocol

Fluid retention is the most common risk factor for mortality and cardiovascular complications in patients with volume-overloaded disease states. The extent of diuresis or fluid removal is frequently determined by physical examination which is subject to inaccuracies.
Bedside ultrasound (US) is a portable tool that brings real-time diagnostic imaging to the patient's bedside. This versatile modality makes it possible for the clinician to investigate patients' extravascular and intravascular volume states. The extravascular volume, particularly in the case of pulmonary edema, can be quantitatively assessed by US of the anterior chest. Intravascular volume is estimated by visualizing the inferior vena cava (IVC) caliber. Taken together, the degree of extravascular lung water and the IVC caliber provide objective data that can guide the clinician to determine the level of diuresis needed to effectively yet safely treat pulmonary edema. 
The objective of this article is threefold: 1) to summarize the findings of previous studies on the efficacy of portable US to guide fluid management, 2) to describe a proposed ultrasound protocol to help guide fluid management, and 3) to elucidate techniques that address the measurement of intravascular and extravascular volumes using portable US.

We describe an imaging protocol that enables the clinician to visualize, in real-time, the patient&#39;s intravascular and extravascular space volumes and set diuresis and fluid removal parameters accordingly for the safe and efficient treatment of pulmonary edema.

Preparing and Administering Oral Tablet and Liquid Medications

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT

Oral medications are the route most preferred by patients and are one of the most commonly used routes of medication administration by providers. Most oral preparations are taken by mouth, swallowed with fluid, and absorbed via the gastrointestinal tract. Oral medications are available in solid forms (e.g., tablets, capsules, caplets, and enteric-coated tablets) and liquids forms (e.g., syrups, elixirs, spirits, and suspensions). Most oral medications have a slower onset of action and, in the case of liquids and swallowed oral medications, may also have a more prolonged effect. Enteric-coated tablets are covered with material that prevents dissolution and absorption until the tablet reaches the small intestine. Additional oral medication routes (not shown in this video) include sublingual administration, in which the preparation is placed under the tongue to dissolve, and buccal administration, which involves placing the medication in the cheek area between the gums and mucus membranes to dissolve.
When preparing and administering oral tablets and liquid medications, the nurse must consider whether the medication is appropriate given the patient&#39;s medical conditions, medication allergies, and current clinical status and when previous doses of the medication have been administered. Patients with altered gastrointestinal function (e.g., vomiting and nausea) should not be given oral medications, since they would not be able to retain them. Oral medications are contraindicated in patients that are unconscious, uncooperative, or unable to swallow due to a medical problem. Medication administration also requires the nurse to be knowledgeable about the medication purpose, adverse effects, and patient preferences. This demonstration will present how to prepare and administer oral medications in both tablet and liquid forms (most common), including the five &#34;rights,&#34; and will discuss medication documentation.

Preparing and Administering Enteric Tube Medications

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT

An enteric tube is a tube that is inserted and passed into the stomach or intestines. Enteric tubes serve multiple purposes, including stomach decompression (through the removal of air, gastric contents, and secretions), enteric feeding, and/or the administration of medications or oral contrast. Enteric tubes are indicated for patients with impaired swallowing and for patients with neurological or other conditions associated with an increased risk of aspiration, or when the patient is unable to maintain adequate oral intake of fluid or calories. There are multiple types of enteric tubes, with their generic names assigned according to the insertion site and the gastrointestinal termination point. For instance, one of the common tube types is the nasogastric tube, which is inserted through a nostril and passed along the upper gastrointestinal tract into the stomach.
When administering medications through an enteric tube, it is important to ensure that the tube terminates in the intended gastrointestinal location. When enteric tubes are initially placed, the position of the tube is verified by X-ray. However, due to gastric peristalsis, enteric tubes may migrate out of their intended termination location. Thus, it is important to confirm the appropriate tube location before administering the medications. Medications administered through an enteric tube are typically oral preparations that must either be crushed into powder by the nurse or prepared in suspension or liquid form by the pharmacy. Prior to crushing any oral medications, it is important to confirm that it is appropriate and safe to do so. For example, administering crushed extended-release medications can lead to toxic medication levels, and crushing medications with cytotoxic or carcinogenic properties can harm the healthcare worker. It is also important to consider the tube lumen size when administering medications, because smaller-bore tubes are more likely to become clogged if the medications are not prepared properly or are not flushed with an appropriate amount of fluid.
This video presents the process of assessing enteric tube placement and administering medications through an enteric tube.

Initiating Maintenance IV Fluids

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT
Hospitalized patients frequently require the administration of intravenous (IV) fluids to maintain their fluid and electrolyte balance. Certain medical conditions that preclude oral fluid intake may necessitate IV fluid administration, with or without electrolytes, to prevent hypovolemia, dehydration, and electrolyte imbalances. Pre-surgical and pre-procedure patients who require anesthesia are often required to be NPO (i.e., nil per os; Latin for &#34;nothing by mouth&#34;) to prevent aspiration and to maintain hydration during the procedure. Post-surgical and post-procedure patients may also require IV fluid administration to increase intravascular volume following surgical blood loss.
IV fluids can be delivered by different types of administrations sets: gravity flow infusion devices, which rely on gravitation force to push the fluid to the patient&#39;s bloodstream, or infusion pumps, which use a pump mechanism that generates positive pressure. While administering maintenance IV fluids using an infusion pump is the most common approach, facility policy; availability of infusion pump equipment; and other limitations, such as a power outage, may necessitate the use of IV gravity tubing. This video describes the approach to initiate maintenance IV fluids using gravity tubing, as well as how to calculate and set the infusion drip rates.

Preparing and Administering IV Push Medications

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT
Intravenous (IV) push is the rapid administration of a small volume of medication into a patient&#39;s vein via a previously inserted IV catheter. Preparations for IV push administration are commonly provided in vials or ampules for withdrawal into a syringe. This method is used when a rapid response to a medication is required, or when the medication cannot be administered via the oral route. For instance, medications commonly administered via IV push are the ones used to treat moderate or severe pain.
Before administrating IV push, it is important to confirm the correct placement of the IV catheter, because the push medication can cause irritation and damage to the lining of the blood vessel and to surrounding tissues. Since IV push medications act quickly, the patients need to be closely monitored after the drug has been administered, and any error can be especially dangerous. It is imperative that the nurse adheres to the five &#34;rights&#34; and three checks of safe medication administration and is knowledgeable about the medication purpose and adverse effects. The nurse should determine the appropriate medication dose, based upon the medication concentration in the container. If the patient receives other IV medications, the nurse needs to ensure the compatibility of the IV push medication with other fluids present in the IV line and should understand the proper IV push administration rate of the medication. The following video will demonstrate how to prepare and administer an IV push injection.

Preparing and Administering Intermittent Intravenous Medications with an Infusion Pump

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT
Primary intermittent intravenous (IV) infusions are delivered alone as volume-controlled infusions, while secondary infusions are delivered with another IV fluid, usually maintenance fluids. Intermittent infusions are delivered over a specific amount of time, which is dictated by the type of medication, such as IV antibiotics. High-volume IV medications, anywhere from 50- to 500-mL infusions, are typically delivered using an infusion pump as either primary or secondary infusions. Infusion pumps deliver IV fluids in a volume-controlled manner, keeping medication side effects to a minimum and helping to prevent nurse medication errors. Careful review of the medication compatibility with maintenance fluids using an approved medication drug guide, pharmacy recommendations in the Medication Administration Record (MAR), and physician orders must be assessed prior to delivering an IV medication. This review will determine if primary or secondary delivery is appropriate based on the risk for patient harm, such as for concentrated electrolyte preparations like potassium.
Certain medical conditions that preclude oral fluid intake, specific medication preparations, or situations that require an increase in the blood concentration of the medication that is faster than possible through the GI tract may require IV medication administration. This video describes the approach to administer primary intermittent IV infusion medications using an IV infusion pump, including acquiring primary intermittent IV infusion medication, priming the IV tubing, preparing the patient, and programming the infusion pump. The infusion pump consists of a main pump PC unit (i.e., the brain) and interlocking modules or channels in which the IV tubing is contained. While the procedure outlines the steps for a specific brand of infusion pumps, the general concepts and principles are consistent across infusion pump brands, although the steps may vary slightly from brand to brand.

Preparing and Administering Secondary Intermittent Intravenous Medications

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT
Secondary intravenous (IV) infusions are a way to administer smaller volume-controlled amounts of IV solution (25-250 mL). Secondary IV infusions are delivered over longer periods of time than IV push medications, which reduces the risks associated with rapid infusions, such as phlebitis and infiltration. In addition, some antibiotic medications are only stable for a limited time in solution. 
The secondary IV medication tubing is connected to the primary macrobore (large internal diameter) IV tubing and is therefore "secondary" to the primary infusion. The secondary solution bag is typically hung higher than the primary infusion bag and is subsequently "piggybacked" on top of the primary IV infusion. This higher position places greater gravitational pressure on the secondary IV solution. As a result, the primary infusion is temporarily paused until the secondary infusion volume has been delivered. This approach ensures that the medication is completely infused due to an immediate return of maintenance IV infusion in the IV line. The secondary IV infusion can be safely delivered when the patient's fluid volume status permits temporarily pausing the delivery of maintenance fluid and in hypervolemia patients. 
This video demonstrates the administration of secondary intermittent IV infusion medications using an infusion pump and using gravity tubing without an infusion pump. This will include a review of acquiring the intermittent secondary IV infusion medication, priming the secondary IV tubing, preparing the patient, calculating the medication administration rate, and setting the secondary IV drip rate.

Discontinuing Intravenous Fluids and a Peripheral Intravenous Line

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT
Intravenous (IV) fluid administration and peripheral IV catheters (PIVs) may be discontinued for a number of reasons. The most common reason for discontinuing IV fluids is that the patient has returned to normal body fluid volume (euvolemia) and is able to maintain adequate oral fluid intake or is being discharged from the hospital. In addition, the Centers for Disease Control Guidelines for the Prevention of Intravascular Catheter-Related Infections (2011) recommends replacing PIVs every 72-96 h in adults to prevent the risk of infection or phlebitis. If the PIV becomes dislodged or if the insertion site demonstrates the signs and symptoms of infection, infiltration, extravasation, or phlebitis, the PIV should be discontinued and replaced. For pediatric patients, the Infusion Nurses Society recommends replacing the PIV only when the IV infusion site is no longer patent or when it demonstrates the signs and symptoms of complications.
This video describes the approach to discontinue IV fluid administration and PIVs.
