 Power analysis indicated that 48 patients randomized equally to each group n24 per group will provide 80 alpha 0.05, beta 0.20 power to detect a 25 difference in total opioid usage during the first 48 hours postoperatively. Fishers exact test will be used to compare binomial proportions of nauseavomiting, sedation, respiratory depression, ileus, and proportion of patients requiring postoperative opioids. In addition, groups will be compared using Kaplan-Meier curves and will be constructed to model time to first oral intake with the log-rank test to compare groups and 95 confidence intervals derived using Greenwoods formula. A Uniform0,1 random number generator will be used to determine treatment allocation and to minimize any covariate imbalances between the ropivacaine and saline groups. Two-tailed values of p0.05 will be regarded as statistically significant.
