Key Points

This study aims to evaluate how sternotomy and thoracotomy affect respiratory muscle strength in patients after surgery.
Sixty patients who underwent sternotomy or thoracotomy were included.
Pulmonary function tests and respiratory muscle strength tests were conducted preoperatively and postoperatively.
Measurements included FEV1, FVC, Pİmax, PEmax, and SNIP for comparison.
There were no significant preoperative differences in FEV1, FVC, Pİmax, PEmax, and SNIP between the two groups.
Postoperative evaluations showed significant decreases in RMS measurements for both surgical groups.

Abstract

Objective: The aim of this prospective clinical study was to investigate the effects of sternotomy and thoracotomy on respiratory muscle strength (RMS). Method: After obtaining ethics committee approval and written informed consent from patients, 60 patients who underwent open heart surgery using sternotomy (Sternotomy Group SG, n=30) or lung surgery using thoracotomy (Thoracotomy Group TG, n=30) were included. Pulmonary function test (PFT) and respiratory muscle strength (RMS) test were performed before and after surgery to compare forced expiratory volume during the first second of the breath (FEV1), forced vital capacity (FVC), maximal inspiratory pressure (Pİmax), maximal expiratory pressure (PEmax), and sniff nasal inspiratory pressure (SNIP) between groups. Results: Preoperative FEV1, FVC, Pİmax, PEmax, and SNIP were similar between groups (p0.05) and were found to be decreased significantly in the postoperative period (p
