术中保温对老年开胸患者生命体征的影响

目的 观察术中保温对老年开胸患者生命体征的影响.方法 将60例行开胸手术老年患者随机分为保温组和对照组,每组30例.保温组患者术中控制室温22～24℃,输入的液体加温至37 ℃,并选用加温至37℃的灌洗液进行胸腔冲洗;对照组患者术中仅控制室温,不采用任何保温措施.测定术前及术后核心体温,比较两组患者围手术期的收缩压、心率、体温变化和寒战发生情况.结果 保温组患者术中体温维持稳定,手术前后体温、收缩压、心率、无明显变化,在人室时、消毒时和手术中1 h及手术结束前差异无统计学意义(P>0.05);对照组患者与术前及保温组比较,术中体温显著下降,收缩压、心率波动明显(P<0.01);而保温组低温(<36℃和<35℃)、寒战发生率显著低于对照组(P<0.01).结论 老年开胸患者术中保温可维持患者体温的稳定,有效预防术中低温和寒战的发生.

Effects of intraoperative warming on vital signs in elderly patients undergoing thoracotomy

Objective To observe the effects of intraoperative warming on vital signs in elderly patients undergoing thoracotomy. Methods A total of 60 elderly patients undergoing thoracotomy were randomly divided into control group (room temperature control alone, n = 30) and warming group (intraoperative warming as well as room temperature control, n = 30) . The systolic blood pressure, heart rate, body temperature and the incidence of hypothermia and shivering were recorded during operation in both groups. Results Compared to control group, the systolic blood pressure, heart rate and body temperature were stabler during operation in warming group (P < 0.01), and the incidence of hypothermia (< 36℃ and < 35℃) and shivering were lower in warming group (P <0.01) . Conclusions Intraoperntive warming can prevent hypothermia and shivering effectively in elderly patients undergoing thoracotomy.
