Abstract

|
|
General anesthesia produces cutaneous vasodilation and depresses shivering reflex. Muscle relaxants, too prevent the increase in metabolism secondary to shivering. So anesthetized, paralyzed patient is partially or totally poikilo-thermic, gains heat in hot environment, and loses heat in cold environment. The purpose of this study was to examine the relationship between hot room
- --temperature and body ´ temperature of anesthetized, paralzyed adults undergoing intraabdominal `surgery.
_ The total number of patients in this study was 20, and. the patients were. devided in two groups. Group 1 was consisted of 10 patients who ´w ere anesthetized in 26-29C. roons. Group j was consisted of 10 patients who were anesthetized in 29-32C rooms.
Conclusions are summerized as follows:
1. Maximal permissble room temperature in which no patient gained-´heat above normal body temperature range. was. 27.xC j4or,-:2a;hours_ operation.
1Patients in. "26-2JC-rooms had ormal mean esophagal temperature 2 hours after induction of anesthesia. al.
- 3. _Patients in 29-329C rooms !showed-,heat retention from 30 minutes after induction of anesthesia.
4. The effective methods of treating :pyrexia which was developed when room temperature was
more than -29.4,C was ;to increase =heat= loss by conduction´ -utilizing ice bag orlwater:.cooled_mattres.
5. When; anesthesia was- maintained"above.26C. room--temperature, body temperature should, be
i&,, :,:taken at heist.30, miinutes;;intervgls lar~revention of liyperthermia.
