“…The shoulder is located close to the thorax and great vessels, and the room-temperature irrigation solution passing through the operative region can remove core body heat, which may lead to a considerable decrease in CBT. Although previous studies showed that IPH in arthroscopic shoulder surgery could be prevented with the use of warm irrigation solution [20,21] , other similar studies found no difference between the use of room-temperature irrigation solution and warm irrigation solution [7,22] . Warm irrigation solution facilitates vasodilatation and bleeding during arthroscopy, which leads to surgical eld of view impairment and prolonged duration of surgery.…”

Background: Forced-air warming (FAW) is an effective method of preventing inadvertent perioperative hypothermia (IPH). However, its warming effects can be influenced by the style and position of the FAW blanket. This study aimed to compare the effects of underbody FAW blankets being placed under or over patients in preventing IPH.Methods: Patients (n=100) undergoing elective arthroscopic shoulder surgery in the lateral decubitus position were randomized into either under body (UB) group or the over body (OB) group (50 per group). The core body temperature (CBT) of the patients was recorded from baseline to the end of anesthesia. The incidences of postoperative hypothermia and shivering were also collected.Results: A steady decline in the CBT was observed in both groups up to 60 minutes after the start of FAW. After 60 minutes of warming, the OB group showed a gradual increase in the CBT. However, the CBT still decreased in UB group until 75 minutes, with a low of 35.7℃ ± 0.4℃. Then the CBT increased mildly and reached 35.8℃ ± 0.4℃ at 90 minutes. After 45 minutes of warming, the CBT was significantly different (P < 0.05). The incidence of postoperative hypothermia in the UB group was significantly higher than that in the OB group (P = 0.023).Conclusions: The CBT was significantly better when the underbody FAW blanket was placed over patients compared with under the patients. However, there was not a clinically significant difference in CBT. The incidence of postoperative hypothermia was much lower in the OB group. Therefore, placing underbody FAW blankets over patients is recommended for the prevention of IPH in patients undergoing arthroscopic shoulder surgery.Trial registration: This single-center, prospective, RCT has completed the registration of the Chinese Clinical Trial Center at 13/1/2021 with the registration number ChiCTR2100042071. It was conducted from 14/1/2021 to 30/10/2021 as a single, blinded trial in Sichuan Provincial Orthopedic Hospital.

“…Patients in hypothermia group received 21. 13 Open access infusion compared with 16.61 mL/kg in the normothermia group; however, this difference was not statistically significant (p=0.136). Other variables, such as gender, body weight, duration of operation and mode of anesthesia, showed no statistically significant difference between the two groups of patients.…”

“…9 Recent studies indicate that intraoperative warming successfully reduces the risk of hypothermia and its consequences. [10][11][12][13] However, limited data are available regarding perioperative hypothermia and its relationship to outcomes in the pediatric population. Our study aimed to determine the overall incidence of intraoperative hypothermia and its associated risk factors in pediatric patients with burn.…”

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.

“…al. [15] compared intraoperative forced-air warming with an underbody resistive warming mattress in a study of 90 patients undergoing shoulder arthroplasty randomly assigned between the two methods. The results showed that intraoperative forced-air warming maintained core body temperature better and that fewer patients in the forced-air group were hypothermic as compared with patients in the underbody resistive warming mattress group (13 of 47 patients vs 32 of 44 patients).…”
