Mistral-Air充气式保温毯对全身麻醉新生儿术后凝血功能的影响

摘要

Objective To evaluate the value of mistral-air inflatable blanket in neonatal temperature,postoperative complications,and the influence of the blood coagulation function after surgery undergoing general anesthesia.Methods A total of 60 newborns with laparotomy operation undergoing general anesthesia were randomly divided into two groups,the control group and the observation group,30 persons each group.The newborns were given mistral-air inflatable blanket in the observation group,and conventional methods in the control group,two groups were transferred to Postanesthesia Care Unit by incubator at 37℃.The introperative nasopharyngeal temprature,HR,MAP and SpO2 were recorded before induction (T0),30 minutes during operation (T1),extubated instantly (T2),15 minutes during PACU (T3),30 min during PACU (T4).The extubation time and the incidence of apnoea and hyoxemia were recorded after operation.PT,APTT,TT and Fib were tested before induction and extubated instantly.Results The temperature of intraoperative and postoperative period were higher in the observation group than the control group,the difference was significant(P ＜ 0.05).The heart rates of intraoperative and postoperative period is significantly higher in the control group than the observation group,the difference was significant(P ＜ 0.05);the mean arterial pressure were no significant statistical difference(P ＞ 0.05).The observation group extubation time were less than the control group,the difference was significant (P ＜ 0.05).There was no significant difference about the incidence of hypoxemia and apnea in two groups(P ＞ 0.05).The PT,APTT,TT and Fib in the observation group were better than the control group,the difference between the groups was significant(P ＜ 0.05).Conclusion Mistral-air inflatable blanket can effectively prevent the decrease of the body temperature during operation and PACU,reduce the exduction time and postoperative complications,and protect blood coagulation function.%目的 探讨术中应用Mistral-Air充气式保温毯对接受全身麻醉的新生儿围术期体温、术后并发症及凝血功能的影响.方法 选取行择期开腹手术、接受全身麻醉的足月新生儿60例,随机分为观察组和对照组各30例.观察组对术中新生儿行Mistral-Air充气式保温毯的保温治疗,对照组则选择传统常规无保温毯式保温方法,术后均使用37℃保温箱送入麻醉苏醒室.分别记录新生儿麻醉前(T0),术中30 min(T1),拔管后(T2),入PACU后15 min(T3),30 min(T4)的鼻咽温、心率、平均动脉压、血氧饱和度,记录新生儿拔管时间、拔管后呼吸暂停及低氧血症的发生率,测量T0和T2时新生儿的凝血指标(PT、APTT、TT、Fib).结果 观察组术中及术后苏醒期体温高于对照组,差异有统计学意义(P＜0.05);对照组术中及术后苏醒期心率明显高于观察组,差异具有统计学意义(P＜0.05);观察组拔管时间少于对照组,差异具有统计学意义(P＜0.05);观察组术后PT、APTT、TT、Fib四项凝血指标优于对照组,差异具有统计学意义(P＜0.05).结论 新生儿术中应用Mistral-Air充气式加温毯,能够改善术后凝血功能,有效预防新生儿术中及苏醒期体温降低,缩短拔管时间.
