Abstract

|
|
Purpose:The purpose of this study was to compare the body temperature (BT), blood pressure (BP) and shivering in patients undergoing operation under general anesthesia between the heated humidification circuit tube (HHCT) group and the non-HHCT group.
Methods:Data were extracted from the participants’ medical records from September 1st to December 30th, 2009. The HHCT group consisted of 50 cases who were applied with heated and humidified gas via a specially designed circuit under general anesthesia. The HHCT which was adjusted at 41℃ was applied from induction of general anesthesia to extubation. In comparison, the non-HHCT group consisted of 50 cases who were applied with gas through standard breathing circuit without heat and humidification. Collected data were analyzed by x2 test, t-test and repeated measures ANOVA.
Results: The BT and shivering were significantly different between two groups (p<.001). But the BP was was not signigicantly different between the HHCT group and the non-HHCT group.
Conclusion: The application of heated and humidified gases to patients under general anesthesia was effective in preserving the body temperature and reducing the shivering.
