【摘要】 目的探讨不同保温温度对腹部手术患儿体温变化的影响。方法选取腹部手术患儿90例,所有患儿术中均使用充气加温毯保温。随机分为3组,每组30例,分别为:中档组(38℃),高档组(43℃),综合组(高档43℃1h后,调为中档38℃),手术中持续监测患儿鼓膜温度变化,比较不同温度档的效果。结果三组患儿入手术室后、麻醉后、切皮时的体温比较,差异均无统计学意义(P>0.05);切皮后30、60、90、120min时,综合组体温与中档组、高档组比较,差异均有统计学意义(F=18.522,P<0.001;F=30.123,P<0.001;F=35.098,P<0.001;F=66.017,P<0.001),中档组患儿术中低温、术后寒战的发生率高于其余两组,高档组发热的效率高于其余两组。结论使用充气加温毯时,先调至高档43℃1h后转为中档38℃,可保持婴幼儿腹部手术患儿体温平稳,有效减少低体温及其并发症的发生。更多还原

【Abstract】 Objective To investigate the effects of different grades of heat preservation on infants’ temperature changes during abdominal surgery. Methods A total of 90 infants with abdominal surgery were recruited,and temperature-adjusting blankets with air inflation were applied to all infants to keep warm during surgeries. All infants were randomly divided into 3 groups with 30 cases in each group: middle-grade(38℃),high-grade(43℃) and integrated group(43℃ for 1 hour,and adjusted to 38℃). Tympanal temperature was monitored continuously during the operation and the effects of different temperature were compared. Results There was no statistically significant difference(P>0.05) in the effects of heat preservation among 3 groups when the infants were moved into the operating room,after anesthesia and during skin incision. The temperature in the integrated group had statistically significant difference(F=18.522,P<0.001;F=30.123,P<0.001;F=35.098,P<0.001;F=66.017,P<0.001) compared with the other2 groups in 30,60,90,120 mins after skin incision. The incidence of low temperature during surgery and chill after surgery in the middle-grade group were higher than those in other two groups, and the incidence of fever during surgery in the high-grade group was highest among three groups. Conclusion The method of maintaining the temperature using blankets with air inflation at 43℃ in high-grade for 1 hour and then adjusted to 38℃ in middlegrade can keep infants’ temperature steady during abdominal surgery and reduce the occurrence of hypothermia and its complications effectively.更多还原
