“…As mentioned in our previous studies, ways of preventing of hypothermia in the elderly include the use of external warming devices (covering with a blanket, treating with an electric blanket or a FAW system), increased the ambient room temperature, and administered warm intravenous or skin irrigation solutions. [24] Forced-air warming has been proven to be the most effective way to maintain normothermia during surgery. [25] Although FAW systems are expensive, such costs are worthwhile in shortening the patient's stay in the PACU and reducing the risk of the increased costs of treating complications associated with postoperative hypothermia.…”

Background: Postoperative hypothermia in elderly patients is a well-known serious complication as it impairs wound healing, induces coagulopathy, increases the risk of blood loss, enhances oxygen consumption, and precipitates cardiac arrhythmias. We conducted this randomized controlled trial to evaluate the effect of a forced-air warming system on rewarming elderly patients undergoing total knee or hip arthroplasty. Methods: We recruited 243 elderly patients undergoing total knee or hip arthroplasty between May and December 2016. They were divided into three groups according to a computer-generated randomization table: group C (n = 78, rewarmed with only a regular blanket), group F1 (n = 82, rewarmed with a forced-air warming system set at 38°C), and group F2 (n = 83, rewarmed with a forced-air warming system set at 42°C). The nasopharyngeal temperature was recorded every 5 min for the first half hour, then every 10 min up to the end of the PACU (postanesthesia care unit) stay. The primary outcome was the rewarming time. The rewarming rate, increase in nasopharyngeal temperature (compared to the start of rewarming), hemodynamics, recovery time, and incidences of adverse effects were recorded. Results: No significant differences were found among the three groups in terms of the baseline clinical characteristics, use of narcotic drugs, intraoperative temperature, and hemodynamics ( P > .05). Compared with the elderly patients in groups C and F1, both the heart rate and mean arterial pressure of those in group F2 were significantly increased 20 min after arrival at the PACU ( P < .05). Patients in group F2 had the shortest rewarming time (35.89 ± 6.45 min, P < .001), highest rewarming efficiency (0.028 ± 0.001°C/min, P < .001), and fastest increased nasopharyngeal temperature among the three groups. Moreover, the elderly patients in group F2 had lower incidences of arrhythmia and shivering ( P < .05). Conclusions: The use of a forced-air warming system set at 42°C was shown to be the most effective way of rewarming elderly patients with postoperative hypothermia.

We aimed to compare the efficacy of intravenous bloodfluid warming and forced-air warming systems for the prevention of perioperative hypothermia in pediatric patients under six years of age. Methods: Two-hundred children aged 0-6 years, who underwent elective surgery, were included in the study. Group 1 patients were warmed with forced-air warming system at the operating room. Group 2 patients were warmed with intravenous fluid and blood warming systems at the operating room. During the entire operation, heart rate, SpO 2 , end Tidal CO 2 and esophagus temperature values were recorded at 10-minute intervals. The number of patients, who needed rescue warming, the starting time and duration of rescue warming were recorded. The duration of the anesthesia, the duration of the operation, and the time of recovery were recorded. Results: The groups were compared in terms of mean operating room temperature and body temperature and no statistically significant difference was found between the groups. There was no statistically significant difference between the groups for additional rescue warming need and time to rescue warming. The time to recovery was longer in the patients who needed rescue warming. There was a statistically significant positive correlation between the duration of the operation and the duration of the need for rescue warming with a confidence of 99%. Conclusion: In pediatric patients, i.v. fluid warming systems are as effective as forced-air warming systems in avoiding perioperative hypothermia.

“…[17] Hypothermia occurs when heat loss exceeds metabolic heat production. [18] Although the use of hypothermia in the pediatric population is helpful for treating brain injury and cardiac arrest, [19,20] infants are considered to have a greater risk of developing unplanned hypothermia than adults because of a high body surface area to mass ratio, higher metabolic rate, difference in body size, limited stores of subcutaneous fat, and a less effective regulatory capacity. [5,21–23] Major surgeries can increase the chance of decrease in the infant's CBT.…”

Purpose: Some studies have reported that warmed humidified carbon dioxide (CO 2 ) insufflation in adult laparoscopic surgery could reduce pain and improve the core body temperature (CBT). However, similar studies are lacking in infants. Thus, this study aimed to investigate the clinical effects of warmed, humidified CO 2 insufflation in pediatric patients undergoing major laparoscopic surgeries. Methods: From January 2015 to December 2017, infants who underwent major laparoscopic surgeries in Ningbo Women and Children's Hospital were randomized to Group A (standard CO 2 insufflation) or Group B (warmed humidified CO 2 insufflation, 35°C, 95% relative humidity). Change in CBT at the end of surgery was the primary outcome. Secondary outcomes included surgery time, intraoperative blood loss, oxygen saturation (SO 2 ), and Face, Legs, Activity, Cry and Consolability (FLACC) scale. These variables were compared between the 2 groups. Results: Sixty-three infants (38 females, 25 males) were included; 30 patients were in Group A and 33 in Group B. The diseases treated with the laparoscopic approach included congenital megacolon, congenital diaphragmatic hernia, and intestinal malrotation. No deaths were noted. CBT was significantly higher in Group B at the end of surgery ( P = .021). The occurrence of postoperative shivering ( P = .02), hypothermia ( P = .032), bowel movement ( P = .044), and hospital stay ( P = .038) was significantly different between the 2 groups; Group B had less shivering and hypothermia occurrence after surgery. Moreover, Group B demonstrated a more rapid postoperative recovery of bowel movement and shortened hospital stay than Group A. There was no statistical difference in operative time ( P = .162), intraoperative blood loss ( P = .541), SO 2 ( P = .59), and FLACC scale ( P = .65) between the 2 groups. Conclusion: The use of warmed humidified CO 2 insufflation in infants undergoing major laparoscopic surgery was helpful for maintaining normothermia and was associated with several positive postoperative outcomes, including less shivering and hypothermia, faster recovery of bowel movement, and shortened hospital stay.
