不同保温措施对患儿全身麻醉后体温的影响

目的:探讨不同保温措施对患儿全身麻醉后体温的影响,以选择最佳的保温措施。方法:选择2016年1月-2017年6月我院300例择期需要手术的患儿,按照随机数字表法分为对照组(n=60)和实验组(n=240),实验组根据不同的保温措施分为输液输血加温组(A组)、身体包裹组(B组)、冲洗液加温组(C组)、加热毯组(D组),每组60例。所有患者术中均常规加盖棉被,室温控制在24~26℃,对照组不再采取另外的保温措施。观察并记录各组患儿在入室不同时间的鼻咽温和肛温。结果:A、C组鼻咽温和肛温随着时间的推移逐步下降,且入室90 min后较入室时明显降低,差异均有统计学意义(均P0.05);B组在入室后鼻咽温和肛温维持在比较稳定的水平(均P0.05);D组鼻咽温和肛温随着时间的推移逐步上升,在入室90 min后较入室时显著升高,差异具有统计学意义(均P0.05)。结论:首选加热毯保温能够维持全身麻醉的患儿体温正常,提高麻醉后的安全性,其次选身体包裹保温,必要时可联合应用多种保温措施。

Effects of Different Insulation Measures on Body Temperature of Children after General Anesthesia

ABSTRACT Objective: To study the effect of different insulation measures on body temperature of children after general anesthesia,so as to select the best insulation measures. Methods: A total of 300 children who needed to be operated on in Yantaishan Hospital of Yantai during January 2016 to June 2017, were selected and randomly divided into control group (n=60) and experimental group (n=240); the experimental group was further divided into infusion and transfusion heating group (group A, n=60), body package group (group B, n=60), flushing liquid heating group (group C, n=60) and heating blanket group (group D, n=60) according to different insulation measures. All children were routinely covered with a quilt, during the operation, room temperature was controlled at 24 to 26 degrees Celsius, the control group did not take additional insulation measures.The nasopharyngeal temperature and anal temperature of each group were observed and recorded at different time after entering into the room. Results: The nasopharyngeal temperature and anal temperature of group A and group C decreased gradually with the passage of time; 90 min after entering into the room, it was obviously lower than that at the beginning of entering into the room, the differences were statistically significant (all P<0.05). The nasopharyngeal temperature and anal temperature of group B remained stable after entering into the room (all P>0.05). The nasopharyngeal temperature and anal temperature of group D increased gradually with the passage of time, 90 min after entering into the room, it was obviously higher than that at the beginning of entering into the room, the differences were statistically significant (all P<0.05). Conclusion: Preferred heating blanket insulation can maintain children with general anesthesia in normal temperaturem,and improve the safety after anesthesia,followed by the selection of body wrapped insulation, when necessary, a variety of insulation measures can be combined to apply.
