Abstract

Background and objective: Perioperative hypothermia causes numerous postoperative complications. Maintaining normothermia is challenging during major open abdominal surgery because heat is lost from the abdominal cavity by evaporation.  Numerous studies demonstrate that convective heating (forced-air system) is among the most effective methods of preventing intraoperative hypothermia.  This study aimed to compare modified lower-body cover and commercial lower-body cover for maintain intraoperative core temperature in major abdominal surgery.


Methods: This prospective randomized controlled trial was conducted in major abdominal surgery patients during November 2014 to October 2015. For forced air warming patients were randomly divided into 2 groups to use with modified lower-body cover (n=20) or use with commercial lower-body cover (n=20). The primary outcome was core temperature in the first 2 hours after anesthetized. GLM and repeated-measures analysis were used to assess.


Results: Demographic parameters of the two groups were similar, as were surgical details. Compare mean of intraoperative core temperature between modified lower-body cover group 35.94±0.65 C with commercial lower-body cover group 36.18±0.81C were not significantly non-inferiority in the first 2 hours after anesthetize (p= 0.313), for a difference of -0.24 C (95% CI -0.23, 0.71).


Conclusion: The forced air warming with modified lower-body can maintain intraoperative core temperature comparable with commercial lower-body cover. We need more research data for support that modified lower-body cover can be used safely as an alternative choice for maintain intraoperative core temperature in major abdominal surgery.
