ObjectiveThe objective of this study was to assess the effectiveness of 0.5% ropivacaine used for parasternal intercostal blocks for postoperative analgesia in pediatric patients undergoing cardiac surgery.DesignA randomized, controlled, prospective, double-blind study.SettingA tertiary care teaching hospital.ParticipantsThirty children scheduled for cardiac surgery with a median sternotomy.InterventionsA 0.5% ropivacaine injection with 5 doses of 0.5 to 2.0 mL on each side in the 2nd to 6th parasternal intercostal space with a total dose of ropivacaine below 5 mg/kg or the same volume of saline before sternal wound closure.Measurements And Main ResultsThe time to extubation was significantly lower in patients administered the parasternal blocks with ropivacaine than in the control group; the mean values were 2.66 hours and 5.31 hours, respectively (p < 0.001). The pain scores were lower in the ropivacaine group compared with the saline group; mean values were 2.20 for the ropivacaine group and 4.83 for the saline group on a scale of 10. The cumulative fentanyl dose requirement over a 24-hour period was higher in the saline group than the ropivacaine group (p < 0.001).ConclusionsParasternal blocks with ropivacaine appear to be a simple, safe, and useful technique of supplementation of postoperative analgesia in pediatric patients undergoing cardiac surgery with a median sternotomy.Copyright © 2012 Elsevier Inc.
