Efficacy of forced‐air warming for preventing perioperative hypothermia and related complications in patients undergoing laparoscopic surgery: A randomized controlled trial

“…Preoperative FAW may prevent perioperative hypothermia (de Brito Poveda, Clark, & Galvao, ), as may intraoperative FAW (Warttig, Alderson, Campbell, & Smith, ). Forced‐air warming may also reduce the incidence of postoperative hypothermia in general anaesthesia (John et al, ) and laparoscopic surgery patients (Pu et al, ). Prewarmed FAW for 10, 20, or 30 minutes preoperatively significantly reduced core temperature changes between non‐prewarmed and prewarmed ( P < .001) general anaesthesia patients; without prewarming, 69% of patients had postanaesthetic hypothermia (<36°C) (Horn et al, ).…”

Control of body temperature and immune function in patients undergoing open surgery for gastric cancer

“…Various methods for controlling body temperature and preventing hypothermia during surgery have been investigated, as well as the effect of temperature on immune response [14][15][16][17][18][19][20][21][22][23]. In our previous study, the combination of warmed infusion fluids, warmed irrigation fluids and an insulation blanket was the most effective method for maintaining body temperature during surgery [20].…”

Randomised trial comparing forced-air warming to the upper or lower body to prevent hypothermia during thoracoscopic surgery in the lateral decubitus position

“…During the first hour after anaesthetic induction, the core temperature decreases by 0.5e1.5 C more likely due to heat redistribution within the body rather than heat loss from the body, 5,7,9,13,17,25 so even external active warming cannot completely prevent hypothermia, 22,26 as shown in our study. After this internal redistribution phase, the core temperature is regulated by a balance between heat loss and gain, thus hypothermia can be treated until the end of surgery by intraoperative active warming.…”
