Design outcomes

Primary

MeasureTime frame
To compare the incidence of hemidiaphragmatic paralysis in both the groups. Timepoint: Pre block, Post block, 2 hours post extubation—

Secondary

MeasureTime frame
Peak Expiratory Flow Rate Diaphragmatic Excursion Time To First Analgesic Requirement Total Analgesic Requirement In The First Twenty Four Hours Intraoperative Hemodynamic Parameters Patient Satisfaction ScoreTimepoint: For Peak Expiratory Flow Rate And Diaphragmatic Excursion Pre Block Baseline Post Block Two Hours After Extubation For Time To First Analgesic Requirement From Completion Of Block Until First Rescue Analgesic In The Postoperative Period For Total Analgesic Requirement Cumulative Requirement During The First Twenty Four Hours Postoperatively For Intraoperative Hemodynamic Parameters Recorded At Regular Intraoperative Intervals For Patient Satisfaction Score Assessed At Twenty Four Hours Postoperatively If you need it in tabular format for protocol submission, I can also prepare that.—
