Purpose: This study is a non-equilibrium control-like experimental study that attempts to develop a nursing intervention plan and to present basic data by grasping the effect of the heating therapy nursing intervention program on patients entering the recovery room after surgery. Method: The subjects of the study were 31 in an experimental group and 31 in a control group who applied one heating therapy program located in D city. The warming therapy was conducted in a recovery room in the range of 38 to 43℃ through a heater. The general characteristics of the subjects were determined by real number and percentage, and a homogeneity test between the experimental group and the control group was determined by 𝑥²-test and independent t-test. The difference in body temperature, pain, and tremor over time between the two groups was determined by repeated measure ANOVA. Results: First, the results of repeated measurements immediately after surgery showed significant differences in body temperature, pain, and tremor between the two groups. Second, temperature comfort showed a significant difference. Conclusion: The results confirmed that there was a positive effect on the patient in the intervention of warming therapy after surgery.

The usefulness of hyperthermia for cancer therapy has been established. The purpose of the present investigation was to access feasibility of heating normal lung and the temperature and power requirement were compared with that for liver as solid organ in rabbits by using radiofrequent heating machine. In this study, 20 rabbits were divided into 2 groups according to the heating site and the method of temperature measurement; in group I : lung heating and temperature measuring in skin, esophagus and lung parenchyme; in group II : liver heating and temperature measuring in skin and liver parenchyme. The results were as follows; 1) When the maximum temperature was almost same in lung heating group and liver heating group, the power for liver heating was lesser required than the power for lung heating (p<0.05). 2) The temperature of esophagus for the measurement of mediastinum temperature was $1.1{\pm}0.9^{\circ}C$ higher than the temperature of lung parenchyme (p<0.05). Therefore the above findings suggest lung, air containing organ, is well heated as same as liver, solid organ. So more active trials of lung heating in the lung cancer must be likely considered. But when the lung is heated, the esophageal temperature is higher than lung parenchyme, so the mediastinum damage must be considered seriously.

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.

The purpose of this study was to investigate the change in blood velocity(mm/sec) when compression and/or heat were applied to the knee joint for the elderly who has both normal and painful legs with osteoarthritis(OA). Experimental compression knee band was prepared from the 3D knee data of the average women in 60's. 3D replica of knee was reduced by 7, 10, and 13% from the nude pattern in course direction. Clothing pressure was measured at the front and back of each healthy and painful knee of elderly women for one minute while standing and sitting on the chair. Blood velocity was measured at 13 cm upper from the mid-patella for 15 minutes. Results are as follows: first, compression or heating treatment itself did not change blood velocity of both legs; second, combination treatment with heating and compression was effective to increase blood velocity. In details, for healthy legs, combination treatments with compression by 10% reduced pattern(about 1.3kPa) and heating($43^{\circ}C$) induced the maximal blood velocity, however, for knees with OA, 7% reduced pattern(about 1.0kPa) with simultaneous heating($43^{\circ}C$) was more effective than other cases. These results indicated that pain and spasticity of knee joint with OA could be reduced by applying heat and compression therapy, where the compression level of painful knee should be slightly lower than of healthy leg.

Purpose: The purpose of this study was to examine the effects of forced air warming on intraoperative and postoperative body temperature, postoperative shivering and pain in patients undergoing laparoscopic cholecystectomy. Methods: A quasi-experimental design with nonequivalent control group was utilized. Fifty eight patients scheduled for laparoscopic cholecystectomy were recruited and assigned to the experimental group (n=29) or control group (n=29). For the experimental group, forced air warming was applied from right after induction and up to one hour after surgery. Body temperature, shivering score and pain score were measured in both groups at 15 minute intervals. Data were collected from September, 2013 to April, 2014. Data were analyzed using t-test, Bonferroni test and repeated measures ANOVA. Results: The experimental group showed higher body temperature than the control group during surgery. After surgery the experimental group showed higher body temperature, lower shivering and less pain compared to the control group. Conclusion: Results show that forced air warming is effective in enhancing body temperature and reducing shivering and pain. Therefore, forced air warming is recommended as an operative nursing intervention.

Purpose: The main question is systematic review of the published in Korea and foreign countries on warming therapy for surgical patients. Methods: The researchers searched at Medline, CINAHL, KERIS, Adult Nursing Association, Korean Society of Nursing Science, Korean Academy of fundamentals of Nursing, and National Assembly Library web site for the published on warming therapy for surgical patients from 1980 to 2008. Words for search were operation/surgery, warming, operation/surgery and warming. Studies were included randomized controlled trial, and there were no restrictions regarding operative phase and outcome measures. Results: 36 published researches that met the criteria were mostly published in foreign countries between 2000 and 2008 and focused on surgery with general anesthesia. Sample size ranged from 21 to 60 subjects, age range between 21 and 60 years of age. Thirty different warming therapies were reported, fifty-two different dependent variables. Outcome indicators included active external warming, intra-operative, and body temperature. 'Positive effects' and 'no effects' equaled. The most frequently reported 'positive effects' were body temperature, shivering, and acid-base balance. No effects were more likely to be heart rate, blood pressure, and hemodynamics. Conclusion: Many types of warming therapy, are reported in the literature with little information about the efficacy of each, many different dependant variables were studied. There were no consistent reports as to length of time used for warming procedures. Overall, the effects of warming therapy are inconsistent. And additional research must be down before any particular method of warming can be used with confidence as to its effectiveness. Attention must be made as to the research design, better measurement of the dependent variables. This review may serve as a base.

Purpose: This study compared the effects of forced air warming and radiant heating on body temperature and shivering of patients with postoperative hypothermia. Methods: The quasi-experimental study was conducted with two experimental groups who had surgery under general anesthesia; 20 patients of group 1 experimented with the Bair Hugger as a forced air warming and 20 patients of group 2 experimented with the Radiant heater. The study was performed from July 3 to August 31, 2006 in a recovery room of an university hospital in a city. The effects of the experiment were measured by postoperative body temperature and chilling score at arrival and after every 10 minutes. The data were analyzed by t-test or ${\chi}^2$-test, repeated measures ANCOVA using SPSS/WIN 12.0. Results: The mean body temperature showed differences between the Bair Hugger group and Radiant Heater group at 40 minutes(F=-2.579, p=.034), 50minutes(F=-2.752, p=.027), and 60 minutes(F=-2.470, p=.047) after arrival to the recovery room. So, hypothesis 1 was partially accepted. The mean score of shivering showed differences between the Bair Hugger group and the Radiant Heater group, but it had no significant meaning. Hypothesis 2 was not accepted. Conclusion: We need more study to explore the effects and side effects of heating modalities to select a more effective heat treatment. The efficiency of heat modalities with regards to cost benefit, time consumption, and patients' discomfort such as burns should be considered.

In the clincal application of Hyperthermia, tissue temperature measurements are made at only a few selecte4 locations because of patient tolerance and practical clinical limitation. Since it is necessary to know the complete carcinoma cell temperature field in order to treat effectively, The difficulty of making such estimates from only a few point compounded because of the lack of knowledge of the carcinomoma cell blood perfusion characteristics. To solve the temperature on carcinoma cell, A noninvasive method (the finite element method) is used. The simulation results show that the finite element method is promising for estimating the complete corcinoma cell temerature distribution, if some knowledge of the blood perfusion pattern is available.

The effect of local hyperthermia of 41 to $43^{\circ}C$ for 30 minutes on radiosensitivity of normal tissue was studied utilizing jejunal crypt microcolony assay. Hyperthermia of this range enhanced the radiation effect and the effect was mainly additive without significant effect on the slopes of cell survival curves. At the isoeffect level of 20 microcolony formation, the thermal enhancement ratio was 1.02, 1.10 and 1.39 for $41^{\circ},\;42^{\circ}\;and\;43^{\circ}C$, respectively. The distribution of microcolony formation along the circumference of jejunum was not uniform, having more colonies around the mesenteric border, and this suggests the effect of uneven cooling by blood circulation.
