Classic rapid sequence induction puts pediatric patients at risk of cardiorespiratory deterioration and traumatic intubation due to their reduced apnea tolerance and related shortened intubation time. A 'controlled' rapid sequence induction and intubation technique (cRSII) with gentle facemask ventilation prior to intubation may be a safer and more appropriate approach in pediatric patients. The aim of this study was to analyze the benefits and complications of cRSII in a large cohort.
Retrospective cohort analysis of all patients undergoing cRSII according to a standardized institutional protocol between 2007 and 2011 in a tertiary pediatric hospital. By means of an electronic patient data management system, vital sign data were reviewed for cardiorespiratory parameters, intubation conditions, general adverse respiratory events, and general anesthesia parameters.
A total of 1001 patients with cRSII were analyzed. Moderate hypoxemia (SpO2 80-89%) during cRSII occurred in 0.5% (n = 5) and severe hypoxemia (SpO2 <80%) in 0.3% of patients (n = 3). None of these patients developed bradycardia or hypotension. Overall, one single gastric regurgitation was observed (0.1%), but no pulmonary aspiration could be detected. Intubation was documented as 'difficult' in two patients with expected (0.2%) and in three patients with unexpected difficult intubation (0.3%). The further course of anesthesia as well as respiratory conditions after extubation did not reveal evidence of 'silent aspiration' during cRSII.
Controlled RSII with gentle facemask ventilation prior to intubation supports stable cardiorespiratory conditions for securing the airway in children with an expected or suspected full stomach. Pulmonary aspiration does not seem to be significantly increased.
经典的快速顺序诱导会使儿科患者面临心肺功能恶化和因呼吸暂停耐受性降低及相关插管时间缩短而导致的创伤性插管风险。一种在插管前进行轻柔面罩通气的“控制性”快速顺序诱导和插管技术(cRSII)可能是儿科患者更安全、更合适的方法。本研究的目的是分析一大群患者中cRSII的益处和并发症。
对2007年至2011年在一家三级儿科医院按照标准化机构方案接受cRSII的所有患者进行回顾性队列分析。通过电子患者数据管理系统,审查生命体征数据中的心肺参数、插管条件、一般不良呼吸事件和全身麻醉参数。
共分析了1001例接受cRSII的患者。cRSII期间中度低氧血症(SpO2 80 - 89%)发生在0.5%(n = 5)的患者中,严重低氧血症(SpO2 <80%)发生在0.3%(n = 3)的患者中。这些患者均未出现心动过缓或低血压。总体而言,观察到1例胃反流(0.1%),但未检测到肺误吸。有2例预期困难插管(0.2%)和3例意外困难插管(0.3%)的患者插管被记录为“困难”。麻醉的后续过程以及拔管后的呼吸状况未显示cRSII期间有“隐匿性误吸”的证据。
插管前进行轻柔面罩通气的控制性RSII有助于维持稳定的心肺状况,以确保预期或怀疑饱胃儿童的气道安全。肺误吸似乎没有显著增加。
