Abstract

OBJECTIVE:

The 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.

DESIGN:

A randomized, controlled, prospective, double-blind study.

SETTING:

A tertiary care teaching hospital.

PARTICIPANTS:

Thirty children scheduled for cardiac surgery with a median sternotomy.

INTERVENTIONS:

A 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 RESULTS:

The 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).

CONCLUSIONS:

Parasternal 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.
