Background: Inflammation of
gallbladder bed , CO2
pneumoperitoneum , and intraoperative
patient posture all
plays a
role in the
etiology of pulmonary dysfunction during
laparoscopic cholecystectomy . Aims and
Objectives: The
goal of this study was to detect any changes in pulmonary function following
laparoscopic cholecystectomy using a portable
spirometry instrument, as well as to determine the degree of pulmonary function impairment and
complications . Materials and
Methods: The pre-operative and post-operative
spirometry of 150
patients undergoing
laparoscopic cholecystectomy under
general anesthesia were compared in this prospective
observational study conducted at JLN medical college and attached group of
hospitals after obtaining due permission from the
Institutional Ethics Committee .
Spirometry was performed preoperatively to determine baseline values
forced vital capacity (FVC),
forced expiratory volume in 1 s (FEV1), and
peak expiratory flow rate (
PEFR ). Those
who were unable to complete the required maneuvers were not included in the study. Pulmonary function testing was performed thrice after
surgery , on days 1, 2, and 3 after
surgery . To achieve a VAS score of <4, enough
pain alleviation was provided. The paired t-test was used to compare
spirometry values.
Results: Between the preoperative and immediate post-operative periods, significant changes in FVC, FEV1, and
PEFR were detected, indicating restrictive
ventilator dysfunction.
Conclusion: After
laparoscopic cholecystectomy ,
light restrictive respiratory disturbances were noted with quick recovery of pulmonary function, potentially lowering post-operative pulmonary
morbidity and
mortality .
