Abstract

This study was designed and undertaken to find out the effect of preoperative deep breathing education on recovery of postoperative pulmonary function. This experiment was done with a nonequivalent pre - test/post - test design using deep breathing
education with incentive spirometer or demonstration alone. We compared the degree of perceived pulmonary function recovery at postoperative 72 hours in groups.
The subjects of this study were collected 46 patients who had received upper abdominal operation in St. Paul Hospital, Catholic University Medical College, and Kangnam Scared Heart Hospital and Kangdong Scared Heart Hospital, Hallym University period
from June 15th, to August 7th, 1992 They were divided into the cotrol group of 15 patients, experimental group I (deep breathing exrcise, DBE) of 15 patients and experimental groupⅡ(incentive spirometer, IS) of 16 patients. The control group had no education preoperatively, experimental groupⅠhad received instruction and saw the demonstration on deep breathing. The experimental groupⅡhad received deep breathing education using the incentive spirometer preoperatively.
The degree of pulmonary recovery function was measured 24, 48 and 72 hourspostoperatively by peak expiratory flow using analysis method of multiple regression, t-test and ANOVA. Peak expiratory flow was expressed as a ratio of preoperative value.
The degree of perceived pulmory function of the patient was taken by ten points visual analogue and analyzed with ANOVA.
@ES The result were as follows :
@EN 1. The peak expiratory flows reflected the degree of pulmonary function recovery at postoperative 24, 48 and 72 hours were significantly higher in the DBE group and IS group than in the control group. However, there were no significant differences in flows between the DBE group and IS group.
2. The degree of perceived pulmonary function at 72 hours was significantly higher in the DBE and IS group than in the control group, but no significant difference of this degree were observed between the DBE group and IS group.
3. Among the signs of postoperative complications, the significant difference was observed between the experimental groups and the control group only for chest discomfory. The incidence rate of chest discomfort was 40% in the control group.
However, no chest discomfort was observed in the DBE group and IS gorup.
4. The parameterds that significantly affect pulmonary function recovery were anesthetics and group at postoperative 24 hours, group at postoperative 48 hours and group and the duration of operation at postoperative 72 hours. The pulmonary function recovery at postoperative 24 hours were more rapid in using halothane group than in using enflurane group.
The above result suggested that patients with the upper abdominal surgery should received the deep breathing exercise and incentive spirometer before operation for improvement of pulmonary functions and prevention of complications. Since deep
breathing exercise education was more economic compared to incentive spirometer education, deep breathing exercise exercise should be adviced for wider application.
