Clinical Trial Summary

Hypothermia occurs frequently during general anesthesia. This study is to evaluate the efficacy of 10 minutes of prewarming during induction of general anesthesia during urologic surgery.

Description:

Hypothermia is of continuous issue in patients undergoing general anesthesia. During urologic operation (transurethral resection of bladder and prostate), bladder irrigation worsens hypothermia. Hence, various methods including prewarming of the patient are used to maintain core temperature during operation. Prewarming is found to be effective in maintaining core temperature perioperatively by increasing peripheral tissue heat content. However, applying more than 30 minutes of prewarming may be impractical as a clinical routine practice. Hence, developing simple and effective method to prevent hypothermia is expected. Here, the investigators planned to examine the effect of active warming (10 minutes of warming during induction of general anesthesia and prewarmed intravenous fluid intraoperatively) on hypothermia in patients undergoing urologic operation under general anesthesia.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	incidence of hypothermia at the end of the operation	number of patients with hypothermia (<36'C) using esophageal stethoscope will be recorded.	approximately 1-2hours after induction (at the end of operation)
Secondary	change in temperature drop before and end of operation	change in core temperature will be observed	on arrival at the OR upto 1-2hours after induction (at the end of the operation)
Secondary	thermal comfort	thermal comfort scale ( 0= very cold, 5= fine, 10= very hot and uncomfortable) will be used.	upto 1hour after end of the operation (at discharge of postanesthesia care unit)
Secondary	incidence of shivering	4 point shivering scale (0=none, 1=core and neck shivering, 2= upper extremity 3= whole body) will be used.	upto 1 hour after end of the operation (on arrival at the postanesthesia care unit)
