【摘要】 目的:观察将覆盖用全身式保温毯用作垫毯对老年腹部手术患者围术期体温变化的影响。方法:择期行开腹手术,年龄大于65岁的老年患者80例,随机数字表法分为主动保温组(B组)和常规保温组(C组)各40例。将成人全身式保温毯垫于B组患者身下,自诱导开始充气保温直至术毕。测量麻醉诱导前5 min(T0),诱导后15 min(T1)、30 min(T2)、60 min(T3)、90 min(T4)、120 min(T5)、150 min(T6)、180 min(T7)、术毕即刻(T8)以及离开PACU前(出室时,T9)各时点的鼓膜温度,记录术后低体温和寒战发生率,麻醉苏醒期的睁眼时间和拔管时间。结果:与诱导前(T0)鼓膜温度相比,两组诱导后各时点的温度均明显下降,差异有统计学意义(P<0.05);诱导后B组各对应时间点鼓膜温度值(T1-T9)均高于C组,差异有统计学意义(P<0.05)。两组鼓膜温度值的变化趋势相似,但B组在降温期体温下降较C组小;B组低体温和术后寒战发生率均较C组低;术后睁眼和拔管时间较C组短。结论:在全身麻醉开腹手术的老年患者中,将充气式保温毯垫于患者身下使用,具有方便且不影响手术操作,术中保温效果确切,有助于减少低体温及其并发症的发生。更多还原

【Abstract】 Objective To investigate the effectiveness of perioperative core temperature changes in older patients undergoing laparotomy when using forced-air warming blanket. Method 80 patients who aged > 65 years undergoing laparotomy,ASAⅠ-Ⅱ,were randomly divided into two groups,the inflatable heating carpet group( group B) and the normal temperature care group( group C),40 cases in each group. Patients in group B used inflatable heating blanket to keep warm until the operation was completed. To measure the tympanic membrane temperature at each point before induction( T0),after induction 15 min( T1),30 min( T2),60 min( T3),90 min( T4),120 min( T5),150 min( T6),180 min( T7),at the time of operation( T8) and at the time of exit( T9),To record the occurrence rate of postoperative shivering and hypothermia,recovery period’s opening time and extubation time. Results Compared with the tympanic membrane temperature before induction( T0),the temperature in both groups decreased significantly after induction( P < 0. 05). The tympanic membrane temperature( T1-T9) in group B was higher than that in group C( P < 0. 05) after induction. The trend in tympanic membrane temperature was similar in the two groups,but the temperature of group B was lower than that in group C during the cooling period. The occurrence rate of hypothermia and postoperative shivering in group B were lower than that in group C. And the opening and extubation time were shorter than that in group C. Conclusion During undergoing general anesthesia operation of aged patients,the use of inflatable heating pad has no impact during operation. The effect of heat preservation is accurate,and it can also reduce the occurrence rate of complications and hypothermia.更多还原
