Perioperative temperature control: Survey on current practices

Abstract

Introduction: Prevention of perioperative hypothermia decreases morbidity and mortality, as well as hospital costs. This study was conducted to evaluate the level of implementation of protocols in 3 tertiary Spanish University Hospitals.

Material and methods: A survey among anaesthesiologists assessed estimated importance and clinical practice in terms of prevention of perioperative hypothermia. Results were compared depending on their experience. P<.05 was considered significant.

Results: A total of 116 anaesthesiologists answered the survey, of whom 48 (41.3%) were residents, 32 (27.6%) were staff with less than 10 years of experience, and 36 (31.1%) staff with 10 years or more of experience, In a 0-10 importance scale, prevention of hypothermia was scored 7.49±1,79, with no difference between groups (P=.58). Younger staff were more concerned of the end surgery temperature than other colleagues (P=.02). The most usual practice was a combination warming the intravenous fluids and an electric blanket (55%). Only 20% of the anaesthesiologists monitored temperature intra-operatively, even though 75% considered it an important parameter. No unit had a written protocol for prevention of perioperative hypothermia.

Discussion and conclusion: Despite the absence of prevention protocols, the anaesthesiologists were aware of the importance maintaining a normal peri-operative temperature, but this awareness is still not enough to influence their perioperative management to diagnose and prevent hypothermia. A harmonisation of practice at local, regional and national level could improve this practice in the future.
