硬膜外阻滞中寒战与低温的关系

The Relationship Between Shivering During Epidural Bloek and Low temperature Fluids

随机选择腹部以下手术８０例，分为４组，每组２０例，常规硬膜外麻醉。第１组患者术中所使用的输液液体、局麻药、消毒液在使用前常规加温至３５℃；第２组的液体、局麻药加温；第３组的液体加温；第４组所用的滴体均不加温。观察４组中患者寒战情况，结果显示第１组的寒战率明显低于其它３组，第２组与第３组之间无明显差异，第４组则高于其它３组。证明输液液体的低温是硬膜外阻滞中寒战的主要原因。其机理可能是由于低温的液体进入体内后导致机体大量热能丧失。提示保温。

Eighty adult patients with epidural anesthesia were ramdomly divided into four groups.In the first group the fluids,local anesthetic drugs and disinfections used in operation were heated to 35℃ before surgery.In the second,the fluids and local anesthetic drugs were heated.In the third,only fluids were heated.In the fourth,no one was heated.Observering the rate of shivering among four groups, the results showed that the rate of shivering in the first group was striking different than that in other groups.It was the same between 1st and 2nd.The rate in the 4th group was higher than others.It showed that low temperature fluids was the primaty cause of shivering during epidural anesthesia.It was due to low temperature fluids taken into the body made the energy lost.
