Effect of postoperative intermittent positive pressure breathing on lung function
Chest
|February 1, 1984
Summary
Postoperative intermittent positive pressure breathing (IPPB) did not improve pulmonary function in patients undergoing cholecystectomy. Adding IPPB to physiotherapy did not enhance recovery and may worsen vital capacity.
Area of Science:
- Pulmonary Medicine
- Surgical Care
- Respiratory Therapy
Background:
- Postoperative pulmonary complications are a concern after abdominal surgery.
- Physiotherapy is a common intervention to mitigate these complications.
Purpose of the Study:
- To investigate the efficacy of intermittent positive pressure breathing (IPPB) as an adjunct to physiotherapy in improving pulmonary function after cholecystectomy.
Main Methods:
- Randomized controlled trial involving 30 patients undergoing elective cholecystectomy.
- Two groups: one received physiotherapy with IPPB, the other physiotherapy alone.
- Pulmonary function (VC, FRC, PO2) and complications were assessed preoperatively and postoperatively.
Main Results:
- Both groups showed significant postoperative pulmonary function deterioration.
- No significant difference in pulmonary complications between groups.
- The IPPB group experienced a greater depression in vital capacity (VC).
Conclusions:
- In patients receiving postoperative physiotherapy, the addition of IPPB did not generally improve pulmonary function after cholecystectomy.
- IPPB may not be beneficial and could potentially impair recovery of vital capacity in this context.
