A comparison of temperature controlled in the operating room and the postoperative shivering during cesarean section under spinal anesthesia in Udonthani hospital.

Abstract

Background: Postoperative shivering is a frequent event in mother undergoing cesarean section under spinal anesthesia. There are many factors affect to the occurrence of shivering include intravenous fluid, blood loss, duration of surgery and operating room temperature. The incidence of shivering in Udonthani hospital was 33%, most of them (73%) occured in postoperative period.

 Objective: To compare effect of temperature control results in operating room withcontinue switch on, switch off and swap mode of air conditioner from cool to fan for postoperative shivering in mother undergoing cesarean section under spinal anesthesia in Udonthanihospital.

Methods: The quasi-experimental study collected data from 133 mothers undergoing cesarean section under spinal anesthesia during 1st June - 31st August 2015. Samples were randomized to 3 groups (continue switch on, switch off and swap mode of air conditioner from cool to fan with room temperature 20-24, 24-28 and 22-26 °C respectively) recordable shivering incidence include personal information. Data were analyzed in term of frequency, percentage, and chi-square test on SPSS program version 16.0.

Results: Postoperative shivering in 3 groups were 32.6% in first group that switch on the air conditioner (n=43), 4.5 % in second group that switch off air conditioner (n=44) and 10.9 % in third group that swap mode cool to fan in air conditioner (n=46). This was significant statistic difference (p<0.001)

Conclusion: To reduce the postoperative shivering during cesarean section under spinal anesthesia switch off or swap mode of the air conditioner were the good choices.
