회복실에서 정상체운 회복을 위한 피부 가온요법의 효과에 관한 연구 = A Research on rewarming methods for recovery to normal body temperature in the PACU

다국어 초록 (Multilingual Abstract)

Management of shivering and hypothermia in the immediate postoperative period is a major concern of postanesthesia nurse.
This study compared time required to rewarm, incidence of shivering, in hypothermic post operative patients treated with a forced air warmer and warming pad.
The purpose of this study is to develop effective nursing intervention methods to rewarm post operative general surgery patients. External Warming methods principally act by preventing convective heat loss from the skin to the environment. Most of the newer methods of external warming claim to produce active heat gain from the environment to the skin.
The degree to which a warming method results in heat gain from the environment will depend not only on the amount of heat the instrument produces, but also in its success at maintaining that heat near the skin.
This study was to compare time required to rewarm postoperative general anesthesia patients and incidence of shivering in patients treated with forced warm air versus patients treated with a warm pad. In addition, information on vital sign changes, patient's discomforts, general characteristics were gathered.
We use non equivalent quasi-experimental study design. The Experimental groups were treated with forced warm air ＆ The Comparative groups were treated with warm pad.
We measured vital signs, shivering scale, patients discomforts until the patient's temperature recovered normal body temperature. Axillary temperature was measured using ⅣAC temp plus Ⅱ. The ⅣAC temp plus Ⅱ thermometer was calibrated internally prior to study. Necessary calibration adjustments occur automatically through a microprocessor program when the probe is returned to its holder.
The Warm Touch system was used to supply warm air. Warm pad was supplied using the K thermia. Patients were randomly assigned to treatment.
Data were collected on 20 experimental group ＆ 20 comparative group. Data were measured for 50 minutes ＆ analyzed with SPSS PC statistic package.
There were no significant differences between the experimental group ＆ the comparative group. The warm air subjects showed neither significant higher skin temperature nor lower incidence of shivering in warm pad group. The relationships between two group time to rewarm ＆ shivering is obscured. Patients in the warm air ＆ the warm pad groups rewarm at nearly equal rates.
We conclude rewarming equipment doesn't affect patient's temperature recovering time and incidence of shivering in immediate post operative period.
Therefore it's necessary to study the effect of rewarming machine for patient's thermo-resuscitation in PACU repeatedly. We suggest that the research on rewarming in PACU patients should be repeated by various nursing intervention methods.
