“…The inter-group differences between temperatures that persisted until recovery may suggest that pre-warming had an effect in addition to the effect of intraoperative warming. This is consistent with previous reports that the temperature difference persisted when intraoperative warming and pre-warming were performed together [ 14 – 16 , 22 ], while it gradually decreased when intraoperative warming was not performed [ 11 , 12 ].…”

“…In a different study, the team reported that in patients undergoing combined epidural and general anesthesia, 15-min pre-warming between the epidural block and general anesthesia effectively reduced perioperative hypothermia (72% vs. 6%) [ 21 ]. Shin et al [ 22 ] also reported that in patients undergoing combined brachial plexus block and general anesthesia, approximately 14 min of pre-warming during the block effectively reduced perioperative hypothermia (96.2% vs. 57.7%). However, since these studies involve regional anesthesia, its induced effect of additional peripheral vasodilation cannot be excluded.…”

Background: This study aimed to evaluate the efficacy of 10-min pre-warming in preventing inadvertent perioperative hypothermia, which is defined as a reduction in body temperature to less than 36.0℃ during the perioperative period in intraoperative warming patients. Methods: In this prospective randomized study, 60 patients scheduled for elective surgery under general anesthesia lasting less than 120 min were divided into two groups: the 10-min pre-warming group (n = 30) and the control group (n = 30). Patients in the 10-min pre-warming group were pre-warmed for 10 min in the pre-anesthetic area using a forced-air warmer set at 47ºC. Intraoperatively, we warmed all patients with a forced-air warmer. Body temperature was measured using a tympanic membrane thermometer pre- or postoperatively and a nasopharyngeal temperature probe intraoperatively. Patients were evaluated on the shivering and thermal comfort scale in the pre-anesthetic area and post-anesthesia care unit. Results: The incidences of intraoperative hypothermia and postoperative hypothermia were similar in both groups (10.7% vs. 28.6%, P = 0.177; 10.7% vs. 10.7%, P = 1.000 respectively). Body temperature was higher in the 10-min pre-warming group (P = 0.003). Thermal comfort during the pre-warming period was higher in the 10-min pre-warming group (P < 0.001). However, postoperative thermal comfort and shivering grades of both groups were similar.Conclusions: Ten minutes of pre-warming has no additional effect on the prevention of inadvertent perioperative hypothermia in intraoperative warming patients.

“…Various methods have been reported to prevent hypothermia during an arthroscopic shoulder surgery [ 1 , 2 , 8 – 13 ], and only few studies assessing interscalene brachial plexus block (ISBPB), which is widely used for postoperative pain control in shoulder surgery, have been reported [ 8 – 10 ]. A previous study reported that preoperative ISBPB can be useful in preventing hypothermia by reducing the amount of volatile anesthetics in patients undergoing arthroscopic shoulder surgery under general anesthesia [ 8 ].…”

“…A previous study reported that preoperative ISBPB can be useful in preventing hypothermia by reducing the amount of volatile anesthetics in patients undergoing arthroscopic shoulder surgery under general anesthesia [ 8 ]. However, other studies have reported that hypothermia occurs more frequently in elderly patients or when active warming is not performed despite using preoperative ISBPB with general anesthesia [ 9 , 10 ]. As such, the effect of ISBPB on preventing perioperative hypothermia is not clear.…”

Background: Interscalene brachial plexus block (ISBPB) is commonly used with general anesthesia for postoperative pain management in shoulder surgery. This study investigated the incidence of hypothermia and changes in the body temperature in patients undergoing arthroscopic shoulder surgery under ISBPB with propofol sedation.Methods: This retrospective study enrolled 220 patients who underwent arthroscopic shoulder surgery. Patients were divided into general anesthesia (n = 34) and ISBPB with propofol sedation (n = 186) groups, and medical records were retrospectively compared. In addition, patients from the ISBPB group were further divided according to age (elderly, [≥ 65 years]; n = 98 vs. young, [< 65 years]; n = 88), and the incidence of hypothermia and changes in the body temperature were compared. Results: Twenty-seven patients (12.3%) experienced perioperative hypothermia (range; 35.3–35.9℃). The incidence of perioperative hypothermia was 29.4% and 9.1% in the general anesthesia and ISBPB groups, respectively, and there was a significant difference between the two groups (P = 0.002). The incidence of perioperative hypothermia according to age in the ISBPB group was 9.2% and 9.1% in the elderly and young groups, respectively, and there was no significant difference between the two groups (P = 0.983).Conclusions: The incidence of perioperative hypothermia during arthroscopic shoulder surgery under ISBPB with propofol sedation is lower than that under general anesthesia. Furthermore, when using ISBPB with propofol sedation, the incidence of perioperative hypothermia in elderly patients is similar to that in younger patients.

“…Prewarming is recommended for a minimum of 30 min (up to 60 min) [7], but this is impractical in a busy operating room environment. In several subsequent studies [9,10], short-term prewarming for 10-30 min also effectively reduced the incidence of hypothermia in adult patients compared to the control group. Short-term prewarming is recommended to prevent hypothermia in clinical situations where prewarming for > 30 min is not easy [1,3].…”

Background: Short-term prewarming effectively reduces intraoperative hypothermia in adult patients. However, few data exist regarding its efficacy in elderly patients. Elderly people have a reduced ability to regulate their body temperature, which affects the efficacy of prewarming. This study aimed to compare the clinical efficacy of short-term pre-warming in elderly patients with that in adult patients. Methods: We enrolled 25 adult (20-50 years) and 25 elderly (> 65 years) patients scheduled for ureteroscopic stone surgery under general anaesthesia. All patients received preanaesthetic forced-air warming for 20 min. The core temperature was measured using an infrared tympanic thermometer during awakening and nasopharyngeal thermistors during anaesthesia. Incidence and severity of intraoperative hypothermia (< 36°C) was compared. Postoperative shivering and number of patients requiring active warming in the post-anaesthesia care unit were also assessed. Results: Intraoperative hypothermia was more frequent in elderly than in adult patients (58.3% vs. 12.0%; relative risk 2.6; 95% confidence interval 1.5 to 4.6; effect size h = 1.010; p = 0.001). The severity of intraoperative hypothermia showed a significant intergroup difference (p = 0.002). Postoperative shivering was more frequent in elderly than in adult patients (33.3% vs. 8.0%, p = 0.037). A greater number of elderly patients in the post-anaesthesia care unit required active warming (33.3% vs. 8.0%, p = 0.037). Conclusions: The effects of short-term prewarming on the prevention of hypothermia and maintenance of perioperative normothermia are not the same in the elderly and adult patients.
