目的探讨两种不同保温措施在婴幼儿非体外循环下心脏手术中的应用效果。方法选取全身麻醉非体外循环下行心脏手术的婴幼儿患儿60例,按随机数字表法分为观察组和对照组。每组各30例,两组环境温度设定相同,进入手术室前患儿均使用常规棉被覆盖。对照组使用变温水箱连接恒温水毯保温措施,观察组使用充气式升温毯保温措施,并监测术前、术中、术后的核心体温变化。结果观察组和对照组术前(入手术室前)体温分别为:37.0℃±0.18℃、36.9℃±0.21℃,两组比较差异无统计学意义(P>0.05)。两组入手术室后不同时间点(入手术室后5 min、全身麻醉状态5 min、切皮后30 min、切皮后60 min、缝皮结束5 min)的核心体温比较,均差异有统计学意义(P<0.05)。观察组低体温发生率低于对照组(P<0.05)。结论采用充气式升温毯保温措施效果优于采用变温水箱连接恒温水毯,能有效地降低婴幼儿手术过程中低体温的发生率。
Objective To investigate the effect of two different insulation measures in cardiopulmonary bypass surgery. Methods Sixty infants and toddlers undergoing cardiac surgery without cardiopulmonary bypass under general anesthesia were divided into observation group and control group according to random number table. Each group of 30 cases, the two groups set the same ambient temperature, into the operating room before the children were covered with conventional quilts. In the control group, variable temperature water tank was used to keep warm water blanket insulation measures. In the observation group, inflatable warm blanket insulation measures were used and the change of core body temperature before, during and after surgery was monitored. Results The body temperature of the observation group and control group before operation (before operation room) were 37.0 ℃ ± 0.18 ℃ and 36.9 ℃ ± 0.21 ℃, respectively. There was no significant difference between the two groups (P> 0.05). The difference of core body temperature between the two groups at different time points (5 min after operation room, 5 min after general anesthesia, 30 min after skin incision, 60 min after skin incision, 5 min after skin incision) were statistically significant Significance (P <0.05). The incidence of hypothermia in observation group was lower than that in control group (P <0.05). Conclusion Inflatable warming blanket insulation effect is better than using warm water tank to connect the constant temperature water blanket, which can effectively reduce the incidence of hypothermia in infants and young children during operation.
