Intraoperative hypothermia in patients undergoing Total knee arthroplasty: a cross-sectional study from a developing country

Abstract

Background Intraoperative hypothermia is associated with various risk factors, morbidity, and mortality in patients undergoing total knee arthroplasty (TKA), increasing the emotional and financial burden on patients. This study aimed to identify risk factors of intraoperative hypothermia in patients undergoing TKA. Materials and methods All adult patients (⩾18 years) who underwent TKA from January 2016 to December 2017 at a tertiary-care hospital in Pakistan were included in this retrospective, cross-sectional study. Temperature < 36 °C was defined as hypothermia. Results The study included 286 patients (77.6% female) with a mean age of 61.4 ± 10.4 years. The overall proportion of intraoperative hypothermia was 26.6%. Of the total patients, 66.1% underwent bilateral TKA whereas 33.9% underwent unilateral TKA. 73.8% of the patients were ASA Level 2. Only 13.3% of patients had postoperative hypothermia. Conclusion Intraoperative hypothermia was significantly associated with age, bilateral procedure, ASA level and postoperative hypothermia in patients undergoing TKA. The surgeon and the operative team should be aware of the risk factors and the adverse outcomes associated with intraoperative hypothermia, especially in resource constrained settings to plan preventive strategies. Trial registration This study was retrospectively registered on ClinicalTrials.gov on 3rd October 2020. The registration ID is NCT04575246.

Incidence and Risk factors for Intraoperative Hypothermia during Cancer Surgery of Gastrointestinal Tracts: a single-center retrospective study

“…Reasons for this may be there is only a small fraction of patients use the warm device and warm mattress rstly; Secondly, the warming mattress were used only when intraoperative hypothermia has occurred, but it's di cult to treat and therapy while redistribution of heat from the central compartment to the periphery in view of the use of anesthetic drugs or the receipt of large volumes of intravenous uids and irrigation [28] . Thirdly, nurses' unawareness of the importance of the intraoperative hypothermia prevention, and implements of temperature was not standardized and data on timing of hypothermia and rewarming strategies was also not recorded [29] .…”

Construction and validation of a risk prediction model for intraoperative hypothermia in elderly patients undergoing total hip arthroplasty

“…IOH, defined as a core temperature (CT) < 36.0℃ during surgery, is a common complication among surgical patients [ 2 ]. In recent studies, the incidence rate of IOH has ranged from 26.6% to 65% in patients who undergo joint arthroplasty [ 3 – 6 ]. Elderly patients undergoing THA are at high risk of hypothermia during surgery, especially under general anesthesia (GA) [ 7 ].…”
