Description: This quasi-experimental study tested the effects of coached or monitored incentive spirometry in combination with hourly or every other hourly frequencies of deep breathing exercises upon maximal inspiratory volume, mean inspiratory time, forced vital capacity (FVC), maximum oral temperature, maximum respiratory rate, and length of postoperative hospital stay in 40 adults following elective cholecystectomy. The investigator also examined (a) the relationship between analgesia and postoperative deep breathing performance; and (b) the relationships between selected demographic variables, duration of anesthesia, and deep breathing performance, upon the proportion of ventilatory capacity retained on the first postoperative day.

Cholecystectomy significantly compromised ventilatory function. No significant differences were observed between group means on preoperative, day of surgery, or postoperative measures of ventilatory function; on maximum oral temperature; or on comparable indices of deep breathing performance, i.e., maximum inspiratory volume, mean inspiratory volume, the proportion of preoperative maximal inspiratory volume attained postoperatively, and mean sustained inspiratory time per treatment. As a group, the Coached Hourly subjects attempted a lower proportion of assigned treatments than the other groups. However, these differences were not statistically significant.

Analyses of co-variance revealed no significant treatment effects upon measures of ventilatory function obtained on the first postoperative day, when either preoperative or day of surgery measures were employed as co-variates. However, two-way analyses of variance revealed a significant interaction effect of type of nursing care and frequency of treatment upon maximal respiratory rate and length of postoperative hospital stay. A significant inverse relationship (p < .001) was found between age and the amount of analgesia received. A significant inverse relationship (p < .05) was found between analgesia received and the mean inspiratory volume attained during the deep breathing treatments. Significant positive relationships (p < .05) were found between indices of postoperative deep breathing performance and the proportion of ventilatory function retained on the first postoperative day.
