Study of risk factors for intraoperative hypothermia during pediatric burn surgery

Abstract

BackgroundIntraoperative hypothermia (core temperature <36.0°C) is common during the perioperative period and can result in adverse consequences, especially in children. We aimed to determine the incidence of intraoperative hypothermia and its risk factors in pediatric patients during burn surgery.MethodsIn the present study we enrolled 197 pediatric patients with burn injury undergoing surgical debridement and skin grafting. Factors, such as total burn surface area (TBSA), were collected and analyzed to identify the potential risk factors for intraoperative hypothermia.ResultsThe incidence of intraoperative hypothermia among all patients was 17.8%. Compared with patients with normothermia, children with hypothermia were associated with larger TBSA (25% vs 15%, p<0.001) and with less intraoperative active warming (34.28% vs 54.93%, p<0.05). In addition, compared with patients with moderate-degree burn, patients with severe and extremely severe burn were associated with much higher risk of intraoperative hypothermia [severe: odds ratio (OR)=3.805, 95% confidence interval (CI)=1.396-10.368, p=0.009; extremely severe: OR=6.933, 95% CI=2.604-18.462, p<0.001]. TBSA was the only independent risk factor that emerged as being strongly associated with intraoperative hypothermia (OR=1.068, p=0.001) and could be used to predict the occurrence of hypothermia when combined with other factors. TBSA for predicting intraoperative hypothermia by receiver operating characteristic (ROC) curve analysis showed a good predictive ability with an area under the ROC curve of 0.758.ConclusionTBSA is an important risk factor for intraoperative hypothermia in pediatric patients with burn.

Magnitude and associated factors of intra-operative hypothermia among pediatric patients undergoing elective surgery: A multi-center cross-sectional study

“…Hypothermia is a core body temperature of less than 36c 0 frequently encountered in pediatric patients operated under general anesthesia [ 1 , 2 ]. Maintaining normothermia is vital for patient comfort and the prevention of complications caused by hypothermia [ [3] , [4] , [5] ].…”

Can we protect pediatric burn patients from hypothermia in the operating room?

“…Hu et al (Hu et al, 2021) reported an incidence of intraoperative hypothermia of 17.8% in pediatric burn patients. They found that the hypothermia group had higher total burn surface area and burn degree, but less intraoperative active warming was applied in this group.…”

“…Current research findings indicated that factors contributing to intraoperative hypothermia during PCNL for kidney stone treatment include anesthesia-related factors and the impact of fluids [ 35 ]. General anesthesia lowers the patient's thermoregulatory threshold and the administration of medications can lead to muscle relaxation, reducing the inhibitory effect on shivering [ 36 ].…”
