Aspiration is a feared complication of anesthesia and is accompanied by increased morbidity and mortality. Rapid sequence induction (RSI) describes the preferred procedure to perform endotracheal placement of the tubus in emergency cases of patients with an increased risk of aspiration of gastric contents. For more than 50 years RSI has consisted of the application of suxamethonium for neuromuscular blockade because of its fast onset and ultra short duration. Due to the serious side effects of suxamethonium attempts were made to find better alternative neuromuscular blocking drugs, e.g. rocuronium, to perform RSI.
In this small clinical series RSI was performed for general anesthesia of ten pregnant women for Caesarean sections using 1.0 mg/kgBW rocuronium for induction and maintaining deep relaxation until the end of surgery. For rapid reversal of the neuromuscular blockade to a train-of-four (TOF) ratio of 0.9, the µ-cyclodextrin sugammadex was administered at the end of surgery. Major and minor side effects, such as cardiac dysrhythmia, anaphylactic reactions, hoarseness and postoperative nausea and vomiting were documented.
The combination of rocuronium and sugammadex for RSI combines rapid onset and rapid reversal of neuromuscular blockades with avoidance of serious side effects and very comfortable conditions for intubation in all cases. Minor side effects such as hoarseness, throat discomfort (in up to 30%) and myalgia (10%) for up to 48 h were documented.
误吸是麻醉中令人担忧的并发症,会导致发病率和死亡率增加。快速顺序诱导(RSI)是针对胃内容物误吸风险增加的患者在紧急情况下进行气管插管的首选方法。50多年来,RSI一直采用琥珀胆碱进行神经肌肉阻滞,因其起效快且作用时间极短。由于琥珀胆碱的严重副作用,人们试图寻找更好的替代神经肌肉阻滞药物,如罗库溴铵,以进行RSI。
在这个小型临床系列中,对10名孕妇进行剖宫产全身麻醉时采用RSI,诱导时使用1.0mg/kg体重的罗库溴铵,并维持深度肌肉松弛直至手术结束。为了将神经肌肉阻滞快速逆转至四个成串刺激(TOF)比值为0.9,在手术结束时给予了μ-环糊精舒更葡糖。记录了主要和次要副作用,如心律失常、过敏反应、声音嘶哑以及术后恶心和呕吐。
罗库溴铵和舒更葡糖联合用于RSI,兼具神经肌肉阻滞起效快和逆转快的特点,同时避免了严重副作用,且在所有病例中插管条件都非常舒适。记录到了一些轻微副作用,如声音嘶哑、咽喉不适(高达30%)和肌痛(10%),持续时间长达48小时。
