PURPOSE: Perioperative hypothermia (PH) is defined as core body temperature < 36°C during the perioperative period. The incidence of PH is not well established in children because of variations in perioperative temperature monitoring and control measures. We sought to 1) establish the incidence of pediatric PH, 2) assess its adverse outcomes, and 3) identify risk factors in our pediatric population to develop local guidelines for prevention of PH.
METHODS: We conducted a prospective observational cohort study at a single tertiary hospital (KK Women's and Children's Hospital, Singapore) from June 2017 to December 2017 based on existing institutional practice. We recruited patients aged ≤ 16 yr undergoing surgery and determined the incidence and adverse outcomes of hypothermia. We identified risk factors for PH using univariate and multiple logistic regression analysis and used these to develop local guidelines.
RESULTS: Of 1,766 patients analyzed, 213 (12.1%; 95% confidence interval, 10.6 to 13.7) developed PH. Among these cases of PH, only 4.5% would have been detected by a single measurement in the postanesthesia care unit (PACU). Adverse outcomes included a longer stay in the PACU (47 vs 39 min; P < 0.01), a higher incidence of shivering (7.1 vs 2.6%; P = 0.01), and more discomfort (3.8 vs 1.4%; P = 0.02) compared with normothermic patients. Risk factors for PH included preoperative temperature < 36°C, surgery duration > 60 min, ambient operating room temperature < 23.0°C, and several "high-risk" surgeries. Guidelines were developed based on these risk factors and customized according to clinical and workflow considerations.
CONCLUSIONS: Perioperative hypothermia was a common problem in our pediatric population and was associated with significant adverse outcomes. Guidelines developed based on risk factors identified in the local context can facilitate workflow and implementation within the institution.
