Objective: Alveolar bone grafting (ABG) with iliac crest bone graft can be associated with significant pain at the donor site. The On-Q pain pump has been shown to be efficacious in treating postsurgical pain. The aim of this study was to compare the length of postoperative hospital stay in patients undergoing ABG who received the On-Q pain pump at the iliac crest donor site (On-Q+) with that of patients who did not receive the On-Q pain pump (On-Q). Design: A retrospective, cohort study, approved by institutional review board, was performed. Thirty-one consecutive patients in the On-Q group were compared with 38 consecutive patients in the On-Q+ group. The two cohorts were assessed for length of stay. Statistical analysis was performed using the Fisher exact probability test. Setting: Tertiary care academic medical center. Patients: Sixty-nine patients with cleft lip and/or cleft palate (CL/P) undergoing secondary ABG with iliac crest bone graft were operated on between May 1993 and January 2014. Main Outcome Measure: Length of postoperative hospital stay. Results: Mean length of stay in the On-Q patients was 0.52 days versus 0.37 days for the On-Q+ patients. This difference between the two cohorts was not statistically significant (P=.234). Conclusion: Although there is a trend toward a shorter length of stay in our patients who received the On-Q pump, this finding was not statistically significant. Given the expense and additional burden of care associated with the device, we have become more selective in its utilization.
