摘要
目的 观察不同物理干预方法对术中患者体温的影响。方法 选择硬膜外麻醉腹部手术患者 4 5例 ,ASAI～II级 ,按照随机方法分为 3组。对照组 (n =1 6 )常规输液 ;实验 1组 (n =1 6 )输入液体加温至 37～ 38℃ ;实验 2组(n =1 3)输入液体加温同实验 1组 ,并在麻醉前 2h接通水温毯 ,温度控制在 37℃ ,同时用手术薄膜包裹患者四肢和非手术区躯干皮肤。观察 3组患者术前、麻醉后 1 5 ,30 ,6 0 ,1 2 0min和术终肛温 ,以及输液量、尿量、出血量、低体温发生率和寒战等级。结果 手术过程中对照组肛温下降的速度和幅度显著大于实验组 ;实验 2组肛温下降的速度和幅度较实验 1组更为平稳。对照组液体输入引起显著的热量丢失 ,实验组液体输入引起轻微的热量吸收。对照组低温和寒战发生率显著高于实验组。结论 物理法干预能有效预防术中低体温的发生 ,减少与低温有关的并发症。
Objective To examine the effects of various physical interventions on body temperature during surgical operation.Methods 45 patients undergoing laparotomy under peridural anesthesia were observed. All the patients were within ASA grade I～II, and were divided into 3 groups randomly: control group (n=16), who received routine intravenous infusion; experiment group 1 (n=16), whose infusion fluid was preheated to 37～38℃, and experiment group 2(n=13), whose infusion fluid was preheated as was done in experiment group 2; water heating blankets were turned on and adjusted to 37℃ two hours before anesthesia, and the skin of the non operation regions were covered with membranes.Rectal temperature, quantity of the infusion fluid, urine output, bleeding, incidence of hypothermia, and the grade of shivering were observed and recorded.Results During the course of operation, the rectal temperature in control group went down significantly in comparison with that of experiment groups,and temperature was most stable in experiment group 2. It was showed that fluid infusion caused significant loss of heat in control group,and it caused a slight absorption of heat in the experiment groups. The incidence of hypothermia and shivering was significantly higher in control group as compared with that of the experiment groups.Conclusion Physical intervention can effectively prevent hypothermia during operation. As a result, the physical methods may reduce the incidence of complications relating to hypothermia.
