Abstract The aim of this study was to investigate the effect of Incentive Spirometery (I.S) on diaphragmatic excursion (D.E) after mitral valve replacement (MVR) and to determine the cause of increased lung volume during I.S maneuver, if it was attributed to chest wall expansion or to D.E. Thirty male patients had been operated upon for elective MVR with mean age (24.9±3.12) years participated in this study; All of them were trained to use I.S in order to facilitate deep breathing maneuver. D.E. during quiet and deep breathing were assessed by Ultra-Sonography (U.S.) before surgery and at fifth day after Intensive care discharge, also maximal inspiratory volume during I.S. maneuver was recorded for all patients. The results of the current study revealed that the I.S maneuver resulted in significant increase in D.E. during deep breathing. Pre-operatively D.E. was correlated non significantly with the increased inspired volume created by deep breathing. While it correlated significantly after operation. It was concluded that I.S enhance the D.E; also D.E. contributed mainly to deep breathing maneuver post-operatively. |
