Purpose: This study was to examine the changes in cold discomfort according to the type of blanket used after surgery. Methods : Women scheduled for Cesarean Section were divided into two groups. After the surgery, 30 patients were covered with a warming blanket which was set at $40^{\circ}C$ by the warmer and the other 30 patients were covered with an ordinary blanket. Both group's cold discomfort was measured at 5 time points using a mercury thermometer, shivering scale. and subjective thermal sensation scale. Data were analyzed by using mean scores with t-test, paired t-test using the SPSS/WIN program. Result: At 30 min after being covered with the blanket, the axillary temperature had returned to the pre-operation temperature in both groups. At 45 min after being covered with the blanket, the women in the warming blanket group had no further shivering but for those in the ordinary blanket group shivering continued. At 45 min after being covered with the blanket, the women in the warming blanket group had returned to the condition before surgery, but those in the ordinary blanket group continued to complain of cold sensation. Conclusion: This study suggests that use of a warming blanket helps to relieve cold discomfort following surgery. This study is also expected to enhance understanding of the Importance of subjective data by exploring the difference between subjective complaints and objective data about cold discomfort.

Purpose : This study investigated the effects of active warming using a Warm Touch warming system or a cotton blanket in postoperative patients after general anesthesia for abdominal surgery. Methods : This quasi-experimental study utilized two experimental groups and one control group: a cotton-blanket group (n = 25) were warmed with a cotton blanket and a sheet; a forced-air warming group (n = 24) were warmed with a Warm Touch warming system, a cotton blanket, and a sheet; and a control group (n = 25) were warmed with a sheet. Measurement variables were postoperative pain, body temperature, and thermal discomfort. Data were analyzed using a one-way ANOVA, ${\chi}^2-tests$, Fisher's exact test, and a repeated measures ANOVA. Results : The effects of active warming using a Warm Touch warming system and a cotton blanket on postoperative patients was significant in reducing pain (F = 13.91, p < .001) and increasing body temperature (F = 12.49, p < .001). Conclusion : Active warming made a significant difference in pain and body temperature changes. Active warming methods may help patients' postoperative recovery and prevent complications. Further research is needed to explore the effects and side effects of active warming on recovering normothermia.

A 13-year-old female Poodle presented with gallbladder rupture caused by a mucocele and hypoperfusion. The animal had a thermal burn injury caused by a forced-air warming device used for hypothermia during surgery. This could be attributed to two causes. First, the forced-air warming device was used with direct hosing, without attachment to an air blanket, and the heat was concentrated in a single area. Second, perioperative peripheral hypoperfusion hampered heat dissipation and increased the susceptibility to a burn injury. These findings suggest that an air blanket should be used with a forced-air warming device according to the manufacturer's instructions. Furthermore, patients with peripheral hypoperfusion are at a higher risk of burn injuries and require close monitoring.

Background: During head and neck surgery including orthognathic surgery, mild intraoperative hypothermia occurs frequently. Hypothermia is associated with postanesthetic shivering, which may increase the risk of other postoperative complications. To improve intraoperative thermoregulation, devices such as forced-air warming blankets can be applied. This study aimed to evaluate the effect of supplemental forced-air warming blankets in preventing postanesthetic shivering. Methods: This retrospective study included 113 patients who underwent orthognathic surgery between March and September 2015. According to the active warming method utilized during surgery, patients were divided into two groups: Group W (n = 55), circulating-water mattress; and Group F (n = 58), circulating-water mattress and forced-air warming blanket. Surgical notes and anesthesia and recovery room records were evaluated. Results: Initial axillary temperatures did not significantly differ between groups (Group $W=35.9{\pm}0.7^{\circ}C$, Group $F=35.8{\pm}0.6^{\circ}C$). However, at the end of surgery, the temperatures in Group W were significantly lower than those in Group F ($35.2{\pm}0.5^{\circ}C$ and $36.2{\pm}0.5^{\circ}C$, respectively, P = 0.04). The average body temperatures in Groups W and F were, respectively, $35.9{\pm}0.5^{\circ}C$ and $36.2{\pm}0.5^{\circ}C$ (P = 0.0001). In Group W, 24 patients (43.6%) experienced postanesthetic shivering, while in Group F, only 12 (20.7%) patients required treatment for postanesthetic shivering (P = 0.009, odds ratio = 0.333, 95% confidence interval: 0.147-0.772). Conclusions: Additional use of forced-air warming blankets in orthognathic surgery was superior in maintaining normothermia and reduced the incidence of postanesthetic shivering.

Purpose: The purpose of this study was to compare the effects of intravenous fluid warming and skin surface warming on peri-operative body temperature and acid base balance of abdominal surgical patients under general anesthesia. Method: Data collection was performed from January 4th, to May 31, 2004. The intravenous fluid warming(IFW) group(30 elderly patients) was warmed through an IV line by an Animec set to $37^{\circ}C$. The skin surface warming(SSW) group(30 elderly patients) was warmed by a circulating-water blanket set to $38^{\circ}C$ under the back and a 60W heating lamp 40 cm above the chest. The warming continued from induction of general anesthesia to two hours after completion of surgery. Collected data was analyzed using Repeated Measures ANOVA, and Bonferroni methods. Results: SSW was more effective than IFW in preventing hypothermia(p= .043), preventing a decrease of $HCO_3{^-}$(p= .000) and preventing base excess(p= .000) respectively. However, there was no difference in pH between the SSW and IFW(p= .401) groups. Conclusion: We conclude that skin surface warming is more effective in preventing hypothermia, and $HCO_3{^-}$ and base excess during general anesthesia, and returning to normal body temperature after surgery than intravenous fluid warming; however, skin surface warming wasn't able to sustain a normal body temperature in elderly patients undergoing abdominal surgery under general anesthesia.

The purpose of the study was to investigate the effects of Warming Therapy used with patients consistantly before and during surgery to on changes in their body temperatures. The data were collected from patients in a university hospital in Taegu between December 1, 1998 and May 31, 1999. The subjects were selected from patients who were hospitalized for total hip replacement surgery. Thirty participants were assigned to two groups : experimental(Warming Therapy) group and control group. Each group consisted of 15 patients. The research design was a repeated measurement design, using a nonequivalent control group. The Warming Therapy, using a forced-air warming blanket, that is a, 'Bair Hugger' was applied to subjects in the experimental group. The subjects in the group were treated with the 'Bair Hugger' to warm up the whole body for 40 minutes before surgery and upper body and face during the operation. The core temperature was measured using a tympanic thermometer. The body temperature of the patients was measured 13 times every 15 minutes during the surgery. After the operation the body temperature of the patients was measured 4 times every 15 minutes, from the time of arrivial in the recovery room to the time of leaving the recovery room. The SPSS Win 9.0 program was used for data analysis. Specific methods tested were done using ${\chi}^2-test$, t-test, repeated measures ANOVA. The findings of the study are as follows. 1. The first hypothesis, 'The level of tympanic temperature for the experimental group which received Warming Therapy will be higher than that of the control group during the operation', was supported (F=32.16, p=.000). 2. The second hypothesis, 'The level of tympanic temperature for the experimental group which received Warming Therapy will be higher than that of the control group after the operation', was supported.(F=33.36, p=.000) 3. During recovery, shivering was observed one patient in the experimental group and seven patients in the control group. In summary, the findings of the study suggest that the 'Warming Therapy' applied before and during the surgery was a very effective treatment for surgical patients in maintaining the core temperature during surgery
