A Study of The Effect of Waiting time for Operation in the Operating Room on Preoperative Patients

수술환자에 있어 수술실내에서 수술대기 시간이 불안에 미치는 영향에 관한 연구

This study was attempted to provide us with basic information on how to improve understanding with patients for operation, and to offer then better nursing and treatment. This kind of study will help scientific application to nursing practice and operating room. The data was collected by interviewing 29 patients who underwent the elective surgery under the general anesthesia at Y hospital in Seoul. The interview ran from October 15 to December 15, 1989. The research instrument was a anxiety measurement device (SAAI) originally developed by Spielberger, et al and modified by Jung-Tack Kim. 1. Hypothesis Testing Hypothesis one was that there would be a difference in state anxiety level according to a time difference in watiting for operation. This hypothesis was rejected(state.anxiety level one hour before operation P>.05, r-.747, State anxiety level half an hour before operation P>.05, r-.1550, state anxiety level just before operation, P>.05, r=.1099). However, state anxiety, evel appeared to be associated with a longer watiting period, like one day before operation (P<.05, r-.4628). Hypothesis two was that there would be a difference according to state anxiety level of patients for operation. This was rejected. (Change of blood perssure in systolie P>.05 r=.1082, Change of blood pressure in diastolic P>.05, r=.088, Change of pulse rate, P>.05, r-1.909) 2. Examining trait anxiety and state anxiety levels, the average level of trait anxiety was 42.034, and the average level of state anxiety one day before operation was 43,000. The average level of state anxiety was averaged 42.356 in a waiting room for operation. 3. Examining the state anxiety level by time period, the one hour before was 42.379 the level half an hour before 42.276, and the level just before operation 42.414. The low level of state anxiety was due to the fact that premedication was not eliminated. 4. Age and time period like one day before operation was related to state anxiety level (F=5.271, P<.0.01) and blood pressure in waiting room for operation. That is, state anxiety level and blood pressure of patients one day before operation appeared high. Sex was relation to changes of blood pressure ; the blood pressure of male patients appeard higer than of female patients. A marital status was also related anxiety level one hour before operation the married patient for operation showed a higher state anxiety level than that of the unmarried patient for operation. Education was similarily related to trait anxiety level in which highly educated patients show lower levels of trait anxiety than poorly educated ones. Motive for hospitalization was related to state anxiety level for patient one hour before operation (F=6.464, P<.05) likewise, patients who are supposed to undergo operation hastily showed higher levels of anxiety than patients who expect elective surgeries.
