Incentive spirometry did not improve diaphragmatic movement in patients after upper abdominal surgery. Postoperative patients showed chest expansion rather than diaphragmatic activation during incentive spirometry use.

Area of Science:

  • Pulmonary Physiology
  • Surgical Recovery
  • Respiratory Mechanics

Background:

  • Upper abdominal surgery often leads to reduced diaphragmatic activity, impairing lung function.
  • Postoperative diaphragmatic dysfunction is a significant concern affecting patient recovery.

Purpose of the Study:

  • To investigate if incentive spirometry can voluntarily activate diaphragmatic movement in patients with postoperative diaphragmatic dysfunction.
  • To assess the impact of incentive spirometry on diaphragmatic and chest compartment contributions to tidal volume.

Main Methods:

  • Inductance plethysmography was used to measure abdominal and chest compartment tidal volumes.
  • Measurements were taken in eight women preoperatively and on postoperative days 1 and 3.
  • Inspiratory flow was monitored as an index of inspiratory drive.

Main Results:

  • Postoperative patients exhibited a significant decrease in the abdominal compartment's contribution to tidal volume at rest.
  • Incentive spirometry preoperatively increased diaphragmatic movement (abdominal tidal volume).
  • Postoperatively, incentive spirometry led to increased chest compartment tidal excursion without enhancing diaphragmatic movement.

Conclusions:

  • Incentive spirometry failed to elicit increased diaphragmatic movement in patients with postoperative diaphragmatic dysfunction.
  • The findings suggest that incentive spirometry may not be effective in restoring diaphragmatic function after upper abdominal surgery.
  • Alternative or adjunct therapies may be needed to address diaphragmatic dysfunction post-surgery.
