Incorporating this curriculum into training necessitates adherence to the protocol as outlined previously. Ensuring practice through hands on training of both the technical aspects of emergency undocking, as well as delineation of roles of OR personnel, is essential towards successful training. All three sessions of pre-training simulation, debriefing, and post-training simulation are likely required to ensure maximal benefit to the learner.
An attempt should be made to create as realistic a l...

The purpose of this training is to improve robotic surgeons&#39; confidence, knowledge, and proficiency of performing an emergency undocking of the robotic system, and to improve the surgeon&#39;s ability to lead an interprofessional team through effective communication of clearly delineated roles in the event of an emergency undocking. Despite the abundance of personnel and equipment in the operating room, there is a lack of experience managing these crises1,2. Current training requirements of online course work and a short period of proctored cases leave many surgeons feeling their training is inadequate3. Regardless of these feelings of inadequacy, prior studies have established that surgeons will encounter at least 1 OR emergency in their career4. Strategies to improve on these feelings of inadequacy include increasing usage of simulation training5. It is well established that simulation training is becoming inseparable from surgical education6. Prior studies have determined that simulation-based team training is an invaluable tool in helping learners overcome cognitive and behavioral gaps in surgical education and is useful as a tool to allow trainees in sessions with other team members the ability to demonstrate baselines for knowledge and communication skills, while improving performance following combining simulation exercises and debriefing4,7,8,9,10,11.
To improve robotic crisis management, various simulator-training scenarios have been developed1,12,13. While there have been numerous studies examining the effects of team training, there is a dearth of research analyzing training on complex OR scenarios4. During complex OR emergencies, checklists and the clear delineations of roles through effective communication are of paramount importance. In robotic surgery, there is a paucity of literature available outlining protocols or training for this procedure14. Simulation has proven effective in validating checklists for use during operating-room crises to improve surgical care15. Here, we present a training curriculum to allow robotic surgeons to develop the skills necessary to lead an interprofessional team in an emergency undocking of a robotic system. Implementation of this curriculum takes place over three sessions in an in-situ environment, as laid out in Figure 1, and can be used to provide training, demonstrate skills for credentialing, and is easily reproducible in any hospital with a robotic system.

emergency undocking in robotic surgery: a simulation curriculum

The following is a training platform to allow robotic surgeons to develop the skills necessary to lead an interprofessional team in emergency undocking of a robotic system. In traditional robotic training for surgeons, a brief web based overview of performing an emergency undocking is provided during initial introductory training to the robotics system. During such a process, there is no training in delineation of interdisciplinary roles for operating room (OR) personnel. The training presented here uses formative simulation and debriefing followed by a lecture. For the simulation, a modified gynecologic simulator is draped in a steep trendelenburg position consistent with most gynecologic laparoscopic surgery. The training torso is modified using tubing hooked to pressure bags of red food colored IV fluid used to simulate a catastrophic vessel injury on demand. Positioned throughout the operating room setting is an interprofessional team consisting of embedded standardized persons (ESPs) to fulfill the roles of a circulating nurse, scrub nurse, anesthesiologist, and bedside assist surgeon. Robotic surgeons are presented a case scenario necessitating emergency undocking, and given control of the robotic instruments. The scenario is terminated following either successful completion of an emergency undock, or at five minutes due to the emergent nature of the case. A debriefing session with hands on training of the steps to emergency undocking, necessary equipment, troubleshooting techniques, and operating room personnel roles follows the simulation. The learners are presented with a short lecture reemphasizing the material presented in the debriefing for their own self-study. This training results in improved time accessing the patient, improved knowledge, confidence, and completion of critical actions, and can be replicated in most institutions. All robotic surgeons should be able to demonstrate competence in this crucial intervention. A limitation of the curriculum is ability to access the in-situ environment for training purposes.

By incorporating this curriculum as outlined in Figure 1 and the undocking protocol outlined in Figure 2 during training in robotic-assisted surgery, our study demonstrated an overall improvement in the confidence, knowledge, and critical actions performed by the surgeon as demonstrated in Figure 3. Baseline measurements in knowledge and confidence were collected on all participants immediately prior...

Emergency Undocking in Robotic Surgery: A Simulation Curriculum

This training platform is designed to allow robotic surgeons to develop the skills necessary to lead an interprofessional team in emergency undocking of the robotic system. Training includes the utilization of the technology and equipment to perform an emergency undocking, as well as delineation of roles for such a scenario.

The following is a training platform to allow robotic surgeons to develop the skills necessary to lead an interprofessional team in emergency undocking of ...

The overall goal of this simulation curriculum is to better prepare robotic surgeons for this potentially life-threatening scenario. This method can help prepare operating room personnel and robotic surgeons for emergency undocking. The main advantage of this technique is that it focuses on team roles for reducing time until intervention can be performed for the patient.This method can provide insight into proper allocation of resources in an emergency undocking, as well as other operating room emergencies, such as cardiac arrest. Generally, individuals new to this method will struggle because they may have never encountered this scenario. We first had the idea for this curriculum when we discovered learners had a limited knowledge of the emergency undocking process.Visual demonstration of the undocking steps is critical for long-term retention of the skills. After collecting the materials, use a scalpel to make one incision above the umbilicus and one each in the right and lower left quadrants of a hollow, draining torso large enough to accommodate a laparoscopic instrument trocar. To simulate a vessel and subsequent vessel injury, cut one piece of rubber tubing from a water seal chest drain for the vena cava and one for the descending aorta.Using Y-connectors, connect two approximately 12-inch pieces of tubing for the right and left common iliac veins, and two approximately 12-inch tubes for the common iliac arteries to the vena cava and aorta. Create a notch at the distal end of the common iliac artery to allow the simulated blood to escape in the case of a vessel injury, and glue the mock vessels against the posterior wall of the torso. Then, protrude the access point to the vessel through the cephalad portion of the torso.After painting, coat the vessels with a clear enamel spray, and inject red food dye into a one liter bag of IV fluid until the fluid has a color consistent with blood. Then hook the bag to the vessel and place the table in a steep Trendelenburg position. Next, drape the torso with operating room drapes used for laparoscopic surgery or laparotomy, so that the entire table is covered, and place laparoscopic trocars into the training torso through the incisions.Move the robotic patient side cart to the bedside and attach robotic arms to the trocars. Using the trocars, dock the robotic training instrument and camera to the torso, and direct at least four embedded standardized persons to their appropriate positions around the table according to their roles. Then start up the surgeon console so that it is ready for the surgeon to assume control of the robotic instruments.When the console is ready, instruct the surgeon to adjust the positional settings of the console without taking control of the instruments. Introduce the embedded standardized persons to the surgeon and read a case stem. At the end of the case orientation, instruct the surgeon to take control of the instruments and have the anesthesia embedded standardized person initiate bleeding from the vessel.The IV tubing should be wide open, allowing for brisk bleeding. Allow the surgeon up to five minutes to complete the emergency undocking. Then debrief, emphasizing the key points of personnel roles, the key equipment used, including the instrument arms and patient side cart and the use of closed loop communication.The embedded standardized persons can then be repositioned for a second case to reinforce the lessons learned during the debriefing. After incorporating this training curriculum as just demonstrated, robotic surgeons who completed the curriculum reported an increase in confidence when faced with an emergency undocking, compared to their reported baseline levels of confidence and knowledge about the procedure. Undocking times and critical actions performed out of seven possible measured actions, also improved, likely representing a combination of the robotic surgeon's ability to recognize the need for an emergency undocking sooner and having the opportunity to simulate the entire emergency undocking process in an in situ environment with immediate feedback from content experts.Once mastered, this curriculum can be completed in under one hour if it is performed properly. While attempting this procedure, it is important to remember to clearly assign the roles using closed loop communication. Following this procedure, other scenarios can be run to further emphasize the learning.After its development, this technique paved the way for other quality improvement projects within the operating room, including Code Blue drills to maximize patient care. After watching this video, you should have a good understanding of how to perform an emergency undocking of the robot. Don't forget that working with surgical equipment poses an innate risk and that care should always be taken to avoid injury.

Setting Up a Stroke Team Algorithm and Conducting Simulation-based Training in the Emergency Department - A Practical Guide

Time is of the essence when caring for an acute stroke patient. The ultimate goal is to restore blood flow to the ischemic brain. This can be&#160;achieved by either&#160;thrombolysis with recombinant tissue-plasminogen activator (rt-PA), the standard therapy for stroke patients who present within the first hours of symptom onset without contraindications, or by an endovascular approach, if a proximal brain vessel occlusion is detected. As the efficacy of both therapies declines over time, every minute saved along the way will improve the patient&#39;s outcome.
This critical situation requires thorough work and precise communication with the patient, the family and colleagues from different professions to acquire all relevant information and reach the right decision while carefully monitoring the patient. This is a high fidelity situation. In nonmedical high-fidelity environments such as aviation, Crew Resource Management (CRM) is used to enhance safety and team efficiency.
This guide shows how a Stroke Team algorithm, which is transferable to other hospital settings, was established and how regular simulation-based trainings were performed. It requires determination and endurance to maintain these time-consuming simulation trainings on a regular basis over the course of time. However, the resulting improvement of team spirit and excellent door-to-needle times will benefit both the patients and the work environment in any hospital.
A dedicated Stroke Team of 7 persons who are notified 24/7 by a collective call via speed dial and run a binding algorithm that takes approximately 20 min, was established. To train everybody involved in this algorithm, a simulation-based team training for all new Stroke Team members was conceived and conducted at monthly intervals. This led to a relevant and sustained reduction of the mean door-to-needle time to 25 min, and enhanced the feeling of stroke readiness especially in junior doctors and nurses.

Every min counts in acute stroke care. This guide shows how to establish a Stroke Team algorithm and enhance its performance with regular simulation training. The principles of Crew Resource Management (CRM) facilitate a straight workflow, reduce door-to-needle times and increase staff satisfaction.

An Anesthesia, Surgery, and Harvest Method for the Evaluation of Transpedicular Screws Using an In Vivo Porcine Lumbar Spine Model

Pedicle screw fixation is the gold standard for the treatment of spinal diseases. However, many studies have reported the issue of loosening pedicle screws after spinal surgery, which is a serious concern. To address this problem, diverse types of pedicle screws have been examined to identify those with good fixation strength and osseointegration in spine bone. The porcine spine is a good alternative for the human spine in the evaluation of pedicle screws due to the anatomical size, mechanical characteristics, and cost. Although several studies have reported that pedicle screws are efficient in the porcine model, no study has described detailed protocols for the evaluation of a pedicle screw using the porcine model. Here, we describe a detailed method for evaluating transpedicular screws using an in vivo porcine lumbar spine model. The technical details for anesthesia, spine surgery, and harvest provided here will facilitate with the evaluation of the transpedicular screw fixation model.

Mechanical Ventilation Boot Camp Curriculum

Medical management of mechanically ventilated patients is challenging to novice providers. Incorrect management of this population may lead to increased morbidity and mortality. A three-day simulation-based boot camp serves to provide one-on-one instruction with a critical care provider. These intensivists may dispense personalized immediate feedback as learners engage in hands-on practice with a real mechanical ventilator. Multiple different pathologies can be reviewed that may not be encountered in the clinical setting. Learners can visualize immediate consequences of their actions and may troubleshoot and ask questions, all while in a safe learning environment. We describe the use of human-patient simulators connected to breathing simulators and mechanical ventilators. Potential curriculum executors should be aware of the cost of the equipment and the time needed to dedicate to boot camp execution; however, this intensive interactive training has been shown to increase provider competency, knowledge, and confidence in ventilator management. This curriculum outline provides guidance on how to execute a simulation-based boot camp to train providers on the management of mechanically ventilated patients.

Robotic Enucleation of an Intra-Pancreatic Insulinoma in the Pancreatic Head

Pancreatic parenchyma sparing surgery for insulinomas avoids the risk of endocrine and exocrine insufficiency, and potential high-risk anastomoses associated with pancreatic resection. Robotic surgery may be used as an alternative for open pancreatic enucleation without compromising dexterity and 3D-vision.
We present the case of a 42-year old woman who presented with sweating, tremor and episodes of hypoglycemia. A fasting test confirmed endogenic insulin overproduction. After inconclusive CT- and MRI imaging, endoscopic ultrasonography showed a hypoechoic lesion, which was fully within the pancreatic head. Although consent was obtained for pancreatoduodenectomy, robotic enucleation seemed feasible. After mobilization, intraoperative ultrasonography was used to identify the lesion and its relation with the pancreatic duct. Dissection was performed using a traction suture, hot shears and bipolar diathermia. A sealant patch was applied for hemostasis and a drain placed. The patient developed a grade B pancreatic fistula for which endoscopic sphincterotomy was performed; the surgical drain could be removed in the outpatient clinic after 20 days. Prospective studies should confirm the short- and long-term benefits of robotic enucleation of insulinomas.

Here, we present a robotic approach to enucleate an insulinoma in the pancreatic head.

Robotic Lateral Pancreaticojejunostomy for Chronic Pancreatitis

Lateral pancreaticojejunostomy (LPJ) has shown good postoperative outcomes in patients with painful, morphine dependent, chronic pancreatitis (CP). The recent rise of robotic and laparoscopic pancreatic surgery has found benefits such as reduced time to functional recovery. Few studies have reported on the feasibility, technique and outcome of robotic LPJ, especially including transection of the gastroduodenal artery. The present study describes the main steps for robotic LPJ in a patient with painful chronic pancreatitis with a dilated main pancreatic duct. The patient underwent robotic LPJ. The LPJ anastomosis is performed using a running suture technique in a longitudinal side-to-side manner. Routinely, the gastroduodenal artery is transected to drain the entire length of the main pancreatic duct. The patient is in French position; 7 trocars are placed (4 robotic, 2 laparoscopic assistants, 1 liver-retractor). After docking of the robot system, the omental bursa is opened, and the right gastroepiploic artery and vein are ligated at their base at the lower border of the pancreas. Intraoperative ultrasonography is performed in order to determine trajectory of the dilated main pancreatic duct which is opened for its entire length after the gastroduodenal artery has been suture ligated both cranially and caudally from the main pancreatic duct. A Roux limb is created, and a latero-lateral PJ is fashioned using several 3-0 barbed sutures. A stapled jejuno-jejunostomy is created at sufficient distance from the pancreatic anastomosis, aided by a 50 cm suture. The described technique for robotic LPJ is a complex but feasible operation for patients with treatment refractory CP and a dilated main pancreatic duct. Due to its complexity, implementation in high volume centers with extensive experience with CP surgery may improve outcomes.

Robotic lateral pancreaticojejunostomy (RLPJ) may be used in patients with painful, morphine dependent, chronic pancreatitis and a dilated main pancreatic duct. We describe a standardized and reproducible technique for RLPJ, which includes transection of the gastroduodenal artery.

A Rat Carotid Artery Pressure-Controlled Segmental Balloon Injury with Periadventitial Therapeutic Application

Cardiovascular disease remains the leading cause of death and disability worldwide, in part due to atherosclerosis. Atherosclerotic plaque narrows the luminal surface area in arteries thereby reducing adequate blood flow to organs and distal tissues. Clinically, revascularization procedures such as balloon angioplasty with or without stent placement aim to restore blood flow. Although these procedures reestablish blood flow by reducing plaque burden, they damage the vessel wall, which initiates the arterial healing response. The prolonged healing response causes arterial restenosis, or re-narrowing, ultimately limiting the long-term success of these revascularization procedures. Therefore, preclinical animal models are integral for analyzing the pathophysiological mechanisms driving restenosis, and provide the opportunity to test novel therapeutic strategies. Murine models are cheaper and easier to operate on than large animal models. Balloon or wire injury are the two commonly accepted injury modalities used in murine models. Balloon injury models in particular mimic the clinical angioplasty procedure and cause adequate damage to the artery for the development of restenosis. Herein we describe the surgical details for performing and histologically analyzing the modified, pressure-controlled rat carotid artery balloon injury model. Additionally, this protocol highlights how local periadventitial application of therapeutics can be used to inhibit neointimal hyperplasia. Lastly, we present light sheet fluorescence microscopy as a novel approach for imaging and visualizing the arterial injury in three-dimensions.

The rat carotid artery balloon injury mimics the clinical angioplasty procedure performed to restore blood flow in atherosclerotic vessels. This model induces the arterial injury response by distending the arterial wall, and denuding the intimal layer of endothelial cells, ultimately causing remodeling and an intimal hyperplastic response.

Setup and Execution of the Rapid Cycle Deliberate Practice Death Notification Curriculum

Death notification is an important and challenging aspect of Emergency Medicine. An Emergency Medicine physician must deliver bad news, often sudden and unexpected, to patients and family members without any previous relationship. Unskilled death notification after unexpected events can lead to the development of pathologic grief and posttraumatic stress disorder. It is paramount for Emergency Medicine physicians to be trained in and practice death notification techniques. The GRIEV_ING curriculum provides a conceptual framework for death notification. The curriculum has demonstrated improvement in learners&#8217; confidence and competence when delivering bad news. Rapid Cycle Deliberate Practice is a simulation-based medical education technique that uses within the scenario debriefing. This technique uses the concepts of mastery learning and deliberate practice. It allows educators to pause a scenario, provide directed feedback, and then let learners continue the simulation scenario the &#8220;right way.&#8221; The purpose of this scholarly work is to describe how to apply the Rapid Cycle Deliberate Practice debriefing technique to the GRIEV_ING death notification curriculum to more effectively train learners in the delivery of bad news.

Use of 3D Robotic Ultrasound for In Vivo Analysis of Mouse Kidneys

Common modalities for in vivo imaging of rodents include positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound (US). Each method has limitations and advantages, including availability, ease of use, cost, size, and the use of ionizing radiation or magnetic fields. This protocol describes the use of 3D robotic US for in vivo imaging of rodent kidneys and heart, subsequent data analysis, and possible research applications. Practical applications of robotic US are the quantification of total kidney volume (TKV), as well as the measurement of cysts, tumors, and vasculature. Although the resolution is not as high as other modalities, robotic US allows for more practical high throughput data collection. Furthermore, using US M-mode imaging, cardiac function may be quantified. Since the kidneys receive 20%-25% of the cardiac output, assessing cardiac function is critical to the understanding of kidney physiology and pathophysiology.

Robotic Central Pancreatectomy with Roux-en-Y Pancreaticojejunostomy

Central pancreatectomy is a parenchyma-sparing alternative to distal pancreatectomy in patients with a benign or low-grade malignant tumor in the body of the pancreas. The aim of central pancreatectomy is to prevent postoperative life-long endocrine and exocrine insufficiency. The downside of central pancreatectomy is the high rate of postoperative pancreatic fistula, which is the main reason that many surgeons do not routinely use central pancreatectomy in eligible patients. Most studies report open or laparoscopic central pancreatectomy with a pancreatico-gastrostomy anastomosis in adults. This is the first description of a standardized approach to robotic central pancreatectomy with Roux-en-Y pancreaticojejunostomy reconstruction in an adolescent (16-year-old boy) with a pseudopapillary tumor in the body of the pancreas. The operation time was 248 min with 20 mL of blood loss. The postoperative course was uneventful except for the short-term medical treatment for a grade B pancreatic fistula. Robotic central pancreatectomy can be safely applied in selected patients in experienced centers.

Robotic central pancreatectomy may be used in selected patients in experienced centers. This protocol presents all steps and the feasibility of a robotic central pancreatectomy with Roux-en-Y pancreaticojejunostomy in a 16-year-old adolescent patient.

Reoperative Hiatal Hernia Repair

Technical Considerations and Approach to Redo Foregut Surgery

Foregut surgical techniques have advanced significantly over the years and have become increasingly popular. However, new challenges and technical considerations have arisen when dealing with reoperation for complications or surgical failure. This study focuses on the technical considerations and approach when dealing with reoperative foregut surgery, particularly redo&#160;hiatal hernia repair. We describe our approach starting from the preoperative workup to the procedural steps of the surgery. The present study describes the main steps for robotic reoperative hiatal hernia repair in a patient who had previously undergone laparoscopic hiatal hernia repair with Nissen fundoplication but did not present a recurrence of reflux and dysphagia symptoms. The patient is positioned supine with arms out and a footboard for steep Trendelenburg. We place six trocars, including an assistant port and a liver retractor port,&#160;to facilitate visualization and retraction. After docking the robot, we use a combination of electrocautery and sharp dissection&#160;to free the hernia sac and reduce the hiatal hernia. The previous fundoplication is then taken down carefully and the esophagus is mobilized through a transhiatal approach with a combination of blunt and sharp dissection until at least 3 cm of intra-abdominal esophageal length is achieved, after which a leak test is performed. We then perform a crural repair to reapproximate the hiatus with two posterior stitches and one anterior stitch. Lastly, a redo Nissen fundoplication is performed over a bougie, and endoscopy is used to confirm a loose stack-of-coin appearance. By emphasizing the crucial steps of redo hiatal hernia repair, including preoperative evaluation, our goal is to provide an approach for the foregut surgeon to maximize patient outcomes.
