Abstract

 Introduction:Two possible respiratory muscle strategies can be considered during pregnancy. 1) Higher inspiratory intercostal and accessory muscle recruitment, since the increased thoracic volume displacement and pleural pressure swings could also be a consequence of their enhanced action. 2) Similar relative contribution between the diaphragm and the inspiratory intercostal muscles, since the slope of the Pgaversus Poes curve remains constant . Methodology: Study was conducted in 60 female patients .These patients were divided into two groups Group I consisted of 30 pregnant women posted for cesarean section under general anaesthesia. Group II consisted of 30 non pregnant women posted for General Surgeries under General anaesthesia. Results: the distribution of Wilson Risk­Sum­Values in both the groups. In groupI, 21 out of the 30 patients belonged to Wilson score 0 (70%) compared to 23 out of the 30 patients in group II (76.7%). In group I, 6 out of 30 patients belonged to Wilsons score 2 (10%) compared to 2 out of the 30 patients in group II (6.7%). Using chi­square test it was found that there was no statistically changes in Wilsons risk­sumvalues between two groups (P>0.05). Conclusion: The prediction of difficult airway in an obstetric patient is best done using Modified Mallampatti classification in the preoperative period.
