Core Temperature Evaluation in Different Body Parts in Patients Undergoing Laparoscope Surgery under Total Intravenous Anesthesia*

Abstract

Purpose The trend of body temperature change during laparoscopic surgery and the most adequate site for monitoring temperature measurements have not been investigated thoroughly. In this study body temperature change during laparoscopic surgery was measured and measurements of the tympanic, esophageal, and nasopharyngeal core temperatures in surgical patients with total intravenous anesthesia were compared. Methods From February to October 2013, 28 laparoscopic surgical patients were recruited from a tertiary hospital in Seoul. The patients' core temperature was measured 12 times at ten minute intervals from ten minutes after the beginning of endotracheal intubation. Results Repeated measure of core temperatures indicated a significant difference according to body part (p=.033), time of measure (p<.001) and the reciprocal interaction between body part and time of measure (p<.027). The core temperatures were highest at tympany location, lowest at nasopharynx. The amount of temperature change was least for the esophagus (36.10~36.33℃), followed by nasopharynx and tympany. Conclusion The esophageal core temperature showed the highest stability followed by nasopharyngeal and tympanic temperature. Therefore, close observations are required between 10~20minutes after the beginning of the operation. 주요어: 심부체온, 복강경 ìˆ˜ìˆ , ì „ì •ë§¥ ì „ì‹ ë§ˆì·¨ Key words: Core temperature, Laparoscope surgery, Total Intravenous Anesthesia
