Brief Summary:
The study hypothesizes that addition of dexmedetomidine to bupivacaine either in spinal anesthesia or TAP block is more effective and provide better ObsQor-11score than bupivacaine alone. Also, Dexmedetomidine in TAP block might provide a longer pain free time in comparison to intrathecal dexmedetomidine.
Detailed Description:
Aim of the work To compare the quality of recovery (ObsQOR-11) in patients undergoing cesarean sections receiving dexmedetomedine either intrathecally or in the tap block in comparison to patients receiving conventional spinal anesthesia and tap block.
Statistical Analysis I. Sample size In a pilot study on 5 parturient who had undergone elective cesarean section under spinal anesthesia followed by TAP block with bupivacaine alone, the mean ObsQoR-11 at 24 hours was 65±9. In a single factor ANOVA study, sample size of 126 from the 3 groups is needed to detect a difference of at least 10 using the Tukey-Kramer (Pairwise) multiple comparison with study power of 83% and alpha error of 0.05. The common standard deviation within a group is assumed to be 9. The number of envelopes will be increased to 141 (47 per group) to compensate of possible 10% dropout. The sample size was calculated using PASS 15 Power Analysis and Sample Size Software (2017). NCSS, LLC. Kaysville, Utah, USA, ncss.com/software/pass.
II. Statistical analysis Data will be coded and entered using the statistical package SPSS (statistical package for the social science) version 22. Data will be summarized using mean, standard deviation, median, minimum and maximum in quantitative data and using frequency (count) and relative frequency(percentage)for categorical data. Comparisons between quantitative variables will be done using the non parametric Mann-Whitney test. For comparing categorical data, Chi square (x2 ) test will be performed. Exact test will be used instead when the expected frequency is less than 5. P-value less than 0.05 will be considered as statistically significant.
