Comparison of Ultrasonography-guided Bilateral Intercostal Nerve Blocks and Conventional Patient-controlled Intravenous Analgesia for Pain Control After the Nuss Procedure in Children: A Prospective Randomized Study
Patients experience severe pain after pectus excavatum (PE) surgery. The aim of this prospective, randomized study was to compare analgesic effects of ultrasonography-guided bilateral intercostal nerve blocks (UG-ICNBs) with those of conventional patient-controlled intravenous analgesia (PCIA) on acute pain after the Nuss procedure for PE repair in children.Methods:
A prospective randomized study was performed in children with PE who were scheduled for the Nuss procedure. Participants were randomly assigned to receive either UG-ICNBs or PCIA for postoperative analgesia. Faces Pain Scale-Revised scores, opioid consumption, analgesia-associated side effects (respiratory depression, pruritus, nausea, vomiting) during the first 24 hours, and lengths of stay in the postanesthesia care unit (PACU) and hospital were recorded after the surgery.Results:
Sixty-two children undergoing the Nuss procedure were enrolled in the trial. Faces Pain Scale-Revised scores were significantly decreased in the UG-ICNBs group compared with the PCIA group for up to 6 hours after surgery. The opioid doses required in the PACU and during the first 24 hours after surgery were significantly greater in the PCIA group compared with the UG-ICNBs group. Accordingly, patients in the UG-ICNBs group showed a lower incidence of analgesia-associated side effects and faster PACU discharge compared with the PCIA group.Conclusions:
Our study suggests that UG-ICNBs might be more effective than PCIA for postoperative analgesia in children who undergo the Nuss procedure for PE.
