“…Shenoy et al [ 18 ] conducted a study on 60 patients in which the medians of core temperature (°C), peripheral temperature (°C), and core to peripheral temperature gradient (°C) at the baseline were identified as 36.1 (0.8), 32.9 (2.4), and 3.4 (1.7, 4.5) in the pre-warming group, while they were identified as 36 (0.58), 32.1 (2.8), and 3.5 (1.8, 5.1), respectively, in the co-warming group, which was an increased median as compared to our study results. Shenoy et al [ 18 ] showed similar results to our study.…”

Background: Hypothermia is a condition characterized by a decreased body temperature. It takes place when the body is exposed to cold weather or water for a longer period of time. Different types of hypothermia include acute hypothermia, exhaustion hypothermia, and chronic hypothermia. Excessive shivering, breathing difficulty, slurred speech, confusion, drowsiness, a weak pulse, and a loss of consciousness are the symptoms related to hypothermia.Aims: The aim of this study was to see how effective co-warming and pre-warming are at reducing the risk of intraoperative hypothermia.Materials and methods: A randomized, prospective, comparative clinical study was conducted in a population of 60 participants. Participants were divided into two groups. Participants in group A received pre-warming for 30 minutes at 40°C before transport to the operation theater and also received co-warming before induction of anesthesia. Group B includes those who received co-warming at 40°C from the point of induction of anesthesia.Results: The mean age (years) of participants in groups A and B was identified as 43.3 ± 11.84 and 45.93 ± 15.87, respectively. The majority of the participants in the study population were males in groups A and B, with 66.67% and 73.33%, respectively. The medians of core temperature and peripheral temperature at the baseline were identified as 36.80 (36.20 to 37.12) and 32.55 (32.38 to 32.72) in group A. Similarly, it was observed as 36 (35.70 to 36.20) and 32 (31.60 to 32.02) in group B. The medians of core temperature and peripheral temperature after the surgery were identified as 34.50 (34.20 to 35) and 32.65 (31.95 to 33) in group A. Similarly, it was identified as 34 (33.80 to 34.25) and 32 (32.10 to 32.25) in group B. Conclusion:Our study concluded that it is important to prevent hypothermia in patients undergoing surgery under general anesthesia. Pre-operative and intraoperative warming showed a decrease in the rate of fall in core temperature. Hence, both techniques are effective in reducing hypothermia.

“…[ 4 , 27 , 28 ] A previous study investigating only abdominal surgeries reported that co-warming was as effective as prewarming in preventing intraoperative hypothermia. [ 29 ] The possibility of temperature loss was mainly due to intraoperative hypothermia which was minimized by the continued intraoperative warming in their study. [ 29 ] However, the most reasonable explanation is that hypothermia can only be effectively treated by intraoperative active warming after a core-to-peripheral temperature redistribution phase.…”

Background: The incidence of intraoperative hypothermia is still high despite the proposal of different preventive measures during thoracoscopic surgery. This randomized control study evaluated the effects of 30-minute prewarming combined with a forced-air warming system during surgery to prevent intraoperative hypothermia in patients undergoing video-assisted thoracic surgery under general anesthesia combined with erector spinae nerve block. Methods: Ninety-eight patients were randomly and equally allocated to prewarming or warming groups (n = 49 each). The primary outcome was the incidence of intraoperative hypothermia. Secondary outcomes were core temperature, irrigation and infused fluid, estimated blood loss, urine output, type of surgery, intraoperative anesthetic dosage, hemodynamics, recovery time, the incidence of postoperative shivering, thermal comfort, postoperative sufentanil consumption and pain intensity, patient satisfaction, and adverse events. Results: The incidence of intraoperative hypothermia was significantly lower in the prewarming group than the warming group (12.24% vs 32.65%, P = .015). Core temperature showed the highest decrease 30 minutes after surgery start in both groups; however, the rate was lower in the prewarming than in the warming group (0.31 ± 0.04°C vs 0.42 ± 0.06°C, P < .05). Compared with the warming group, higher core temperatures were recorded for patients in the prewarming group from T1 to T6 ( P < .05). Significantly fewer patients with mild hypothermia were in the prewarming group (5 vs 13, P = .037) and recovery time was significantly reduced in the prewarming group ( P < .05). Although the incidence of postoperative shivering was lower in the prewarming group, it was not statistically significant (6.12% vs 18.37%, P = .064). Likewise, the shivering severity was similar for both groups. Thermal comfort was significantly increased in the prewarming group, although patient satisfaction was comparable between the 2 groups ( P > .05). No adverse events occurred associated with the forced-air warming system. Both groups shared similar baseline demographics, type of surgery, total irrigation fluid, total infused fluid, estimated blood loss, urine output, intraoperative anesthetic dosage, hemodynamics, duration of anesthesia and operation time, postoperative sufentanil consumption, and pain intensity. Conclusion: In patients undergoing video-assisted thoracic surgery, prewarming for 30 minutes before the induction of anesthesia combined with a forced-air warming system may improve perioperative core temperature and the thermal comfort, although the incidence of p...

Hipotermia merupakan suatu kondisi dimana tubuh mengalami penurunan suhu di bawah 36 °C dan menjadi salah satu komplikasi yang paling sering terjadi selama fase perioperatif pembedahan abdomen sehingga berdampak pada proses pemulihan pasien. Beberapa metode untuk manajemen hipotermia telah diteliti seperti penggunaan penghangat aktif dan pasif. Namun penggunaannya di rumah sakit belum efektif sehingga manajemen hipotermia belum maksimal dilakukan. Tujuan penelitian ini adalah untuk menganalisis efektivitas penghangat aktif dan pasif dalam manajemen hipotermia pasien dengan pembedahan abdomen di RSUD Bali Mandara. Pada penelitian ini menggunakan desain penelitian pre-experimental static group comparison design dengan rancangan two group pre-post test design. Pada kelompok control (pemberian selimut hangat) terdapat 12 responden dan kelompok intervensi (selimut hangat dan hot water bag) 15 responden. Kedua responden dilakukan pegukuran suhu awal dan pengulangan setiap 15 menit sebanyak 3x. Hasil uji repeated anova menunjukkan bahwa pada kelompok intervensi terdapat efektifitas penghangat aktif terhadap perubahan suhu (p value < 0,05) dan pada kelompok kontrol tidak terdapat efektifitas penghangat pasif terhadap perubahan suhu (p value > 0,05). Hasil penelitan ini dapat diterapkan pada pasien post op abdomen untuk memanajemen hipotermia dan meningkatkan kenyaman pasien post op. .Kata Kunci: keperawatan, manajemen hipotermia, pembedahan abdomen, postoperasi
