Postoperative hypothermia followed by shivering is a common phenomenon in patients undergoing surgery under anesthesia, and should be prevented and treated in postoperative patient care units. This study was conducted to investigate the effect of warmed serum injection on postoperative shivering and recovery period of patients operated under general and spinal anesthesia.
In this clinical trial, patients to be operated on under general and spinal anesthesia were randomly assigned into two groups of test and control. In the test group, patients received warmed intravenous fluids and blood products. All patients were monitored to record vital signs, incidences of hypothermia and shivering, and recovery period.
The collected data were analyzed with repeated measures analysis of variance to detect significant differences between groups and significant changes within groups over time.
The incidence of nausea, vomiting, and shivering in the intervention and control groups was (4.7%, 42%), (2.8%, 16.8%), and (6.6%, 43%), respectively. Patients in the intervention group had higher body temperature than the control group (<0.001). Also, patients under spinal anesthesia had higher body temperature than patients under general anesthesia (<0.001). Blood pressure reduction was also significantly higher in the control group than in the intervention group. The patients who received warm intravenous serum, and especially those who had received spinal anesthesia spent less time in the recovery room (<0.001).
The use of warmed intravenous serum increased the patients' core temperature, reduced their postoperative shivering, and shortened their recovery period. Considering the potential risks associated with hypothermia, using such methods for hypothermia prevention can be highly effective in preventing shivering and prolongation of the recovery period and other potential complications. Anesthesia specialists and technicians are therefore encouraged to use this method as a preventive measure.
术后低体温伴寒战是麻醉下手术患者的常见现象，应在术后患者护理单元中预防和治疗。本研究旨在探讨温血血清注射对全麻和脊麻下手术患者术后寒战和恢复期的影响。
在这项临床试验中，接受全麻和脊麻的手术患者被随机分为试验组和对照组。试验组患者接受温热静脉输液和血液制品。所有患者均进行监测，记录生命体征、低体温和寒战发生率以及恢复期。
采用重复测量方差分析对收集的数据进行分析，以检测组间差异和组内随时间的显著变化。
干预组和对照组恶心、呕吐和寒战的发生率分别为（4.7%，42%）、（2.8%，16.8%）和（6.6%，43%）。干预组患者的体温高于对照组（<0.001）。此外，脊麻患者的体温高于全麻患者（<0.001）。对照组患者的血压下降也明显高于干预组。接受温血静脉血清的患者，尤其是接受脊麻的患者，在恢复室的时间更短（<0.001）。
使用温热静脉血清可增加患者核心体温，减少术后寒战，缩短恢复期。鉴于低体温相关的潜在风险，使用这种方法预防低体温可有效预防寒战和延长恢复期及其他潜在并发症。因此，鼓励麻醉专家和技术人员将其作为预防措施使用。
