Protokol SCI-hayvanlar (Şekil 1B) ABP uzun vadeli ayrıntılı bir analiz için, bir telemetri cihazı ile kombine olacak yeni bir JAVA platformu AD Algılama yazılımı detaylı bir uygulamasını açıklamaktadır. Bu da gün süresince sporadik olarak ortaya spontan AD olaylarını tespit etmek için AKB desen karakterizasyonu için izin veren ilk yazılımdır. Bir iyi karakterize T3 SCI hayvan modeli spontan AD sıklığı, pressör tepkisi ve süresini tespit etmek için yazılımın fonksiyonel...

Otonom disrefleksi (AD) servikal veya yüksek göğüs segmentlerinde akut veya kronik spinal kord yaralanması (SKY) sonrası bireylerde hayatı tehdit eden acil bir durumdur ve genellikle kalıcı hipertansiyon ve bradikardi 1 atakları ile karakterizedir. AD esas genellikle sempatik aktivite ve vasküler tonus 1-4 kontrol spinal sempatik preganglionik nöronlara Supraspinal merkezlerden girdi sağlamak spinal yollar inen bozulması neden olur. AD bölüm 300 mmHg kadar sistolik kan basıncında ani bir artış (SKB) ile karakterize olan nöbetler, kafa içi kanama, miyokard enfarktüsü ve hatta ölüme 5-8 yol açabilir tedavi edilmediği takdirde. Zararlı ve zararlı olmayan uyaranların çeşitli bağırsak ve mesane distansiyonu, spazmlar, bası yarasının, mesane kateterizasyonu veya iyatrojenik prosedürler 9-12 dahil olmak üzere AD tetikleyici olarak hareket ederler. resp AD zamansal gelişimiSCI için onse hem insan 9 ve hayvan modellerinde 13,14 araştırılmıştır. Tipik olarak bu çalışmalar (örn ürodinami, insanlarda veya hayvanlarda kolorektal şişkinlik penis vibrostimulations) MS zamansal gelişimini belirlemek için bir &quot;neden AD &#39;yöntemi kullandık. Böyle bir yaklaşım, AD zamansal gelişimi doğru belirlenmesi önleyebilir izole edilmiş zaman noktalarında tekrar değerlendirme için ihtiyaç ile sınırlıdır. İnsanlarda 24 saatlik kan basıncı izleme kullanımı, seri kan basıncı ölçümleri önceden belirlenmiş aralıklarla yapılmasına olanak tanır. Bu teknik son zamanlarda kronik SKY olan hastalarda spontan meydana gelen AD izlemek için istihdam edilmiştir. Hayvan modellerinde, solid-state basınç dönüştürücüler giderek kronik beat-by-dövmek arteriyel kan basıncı izlemek için kullanılmaktadır. Son zamanlarda, Rabchesvky ve ark. (2012), ortalama kan basıncı bir saniye ortalamaları çıkarılan bir algoritma geliştirdi (MAP) birBir hareketli ortalama eşik 15 karşılaştırılır d. Spontan AD etkinlik 10 mmHg ya da 10 bpm veya daha büyük bir sıcak damla ile eş zamanlı olarak eşiğin üstünde daha MAP tepe göre karakterize edilmiştir. İşte AD Algılama Algoritması yerleşik bir roman JAVA yazılım sunulmuştur. Bu algoritma arteriyel kan basıncı (AKB) ve kendiliğinden meydana gelen AD olay göstergesidir kalp hızı (KH) önceden belirlenmiş desenler tespit ederek çalışır. Kullanıcı el &#39;algılama algoritması&#39; kolayca ilgi belirli parametrelere özelleştirilebilir böyle bir yazılım tüm giriş değişkenleri ayarlamak mümkün değildir. Yazılım aynı zamanda hemodinamik parametrelerin günlük ritmisite 16 analiz edilebilir şekilde belirli bir çağ haline ABP ve İK dichotomize yapabiliyor. Mevcut yazıda, ayrıntılı bir açıklama telemetri cihazları implante ve SCI ameliyatı yapmak için kullanılan cerrahi tekniğin verilir. eskiamples da AD Algılama yazılım sonrası işleme yetenekleri açısından nasıl kardiyovasküler fonksiyon sağlanır sonrası omurilik değiştirilir. Karşılaştırma amaçları doğrultusunda, yöntem ve sonuç kolorektal distansiyon olarak bilinen bağlı AD için bir yöntem elde edilen (CRD), aynı zamanda açıklanmaktadır.

development of an algorithm to perform a comprehensive study of autonomic dysreflexia in animals with high spinal cord injury using a telemetry device

Spinal cord injury (SCI) is a debilitating neurological condition characterized by somatic and autonomic dysfunctions. In particular, SCI above the mid-thoracic level can lead to a potentially life-threatening hypertensive condition called autonomic dysreflexia (AD) that is often triggered by noxious or non-noxious somatic or visceral stimuli below the level of injury. One of the most common triggers of AD is the distension of pelvic viscera, such as during bladder and bowel distension or evacuation. This protocol presents a novel pattern recognition algorithm developed for a JAVA platform software to study the fluctuations of cardiovascular parameters as well as the number, severity and duration of spontaneously occurring AD events. The software is able to apply a pattern recognition algorithm on hemodynamic data such as systolic blood pressure (SBP) and heart rate (HR) extracted from telemetry recordings of conscious and unrestrained animals before and after thoracic (T3) complete transection. With this software, hemodynamic parameters and episodes of AD are able to be detected and analyzed with minimal experimenter bias.

Development of an Algorithm to Perform a Comprehensive Study of Autonomic Dysreflexia in Animals with High Spinal Cord Injury Using a Telemetry Device

The catheter of a telemetry device is implanted into the abdominal aorta in order to continuously collect beat-by-beat hemodynamic data from animals pre and post-high thoracic spinal cord transection. A novel JAVA software was employed to analyze hemodynamic parameters as well as frequency and intensity of spontaneous episodes of autonomic dysreflexia.
