Comparison of intraoperative core temperature between forced-air warming with modified lower-body cover and with commercial lower-body cover in major abdominal surgery
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 ± 0.65๐C with
commercial lower-body cover group 36.18 ± 0.81๐C
were not significantly non-inferiority in the first 2 hours ๐C (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.
