To Evaluate the Effect of Prewarming in Prevention of Inadvertant Peri-Operative Hypothermia and Shivering
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 5
Abstract
Abstract: Core temperature is closely maintained physiological parameters as enzyme systems in the body have narrow temperature changes in which they function optimally. Inadvertant perioperative hypothermia (core temperature of < 360C) is preventable problem. Regular recording of temperature is the key to prompt identification and management. To Evaluate the Effect of Prewarming In Prevention of Inadvertant Peri-Operative Hypothermia and Shivering. To assess the effect of prewarming on itraoperative hypothermia, post anaesthetic shivering. To assess time taken for the patient from emergence from anaesthesia. 60 patients of ASA I,II and III status posted for elective ear surgery with age 18years to 60years divided in two groups,Study group (GroupP) received warming preoperatively for 20minutes,Control group (GroupC) did not receive warming preoperatively.Level1 Equator warmer used for warming.Both group received warming intraoperatively. Surface and Core temperature (Nasopharyngeal) charted intraoperatively every 15minutes and time for emergence from anaesthesia was noted.Shivering and thermal comfort were graded postoperatively. The distribution of mean core temperature,mean surface temperature and distribution of mean post anesthetic shivering score are significantly higher in GroupP compared to GroupC(P-value<0.001 for all).The distribution of mean thermal comfort score is significantly higher in GroupP compared to GroupC.The distribution of mean time of recovery is significantly higher in GroupC compared to GroupP(P-value<0.05 for all). Preoperative warming for 20minutes results in minimal reductions of core temperature intraoperatively and less IPH in patients undergoing ear surgeries under general anaesthesia.
