IntroductionContinuous thoracic epidural analgesia is useful in the management of infants following thoracotomy. Concerns about drug accumulation and toxicity limit the amount of amide local anesthetics that can be delivered. Continuous epidural infusions of the ester local anesthetic chloroprocaine result in little drug accumulation allowing for higher infusion rates. We retrospectively compared patients managed with 1.5% 2- chloroprocaine or 0.1% ropivacaine epidural infusions to determine if the increased infusion rate resulted in similar or improved analgesia.MethodsThis retrospective cohort comparison consisted of full term infants 6 months or younger who underwent thoracotomy for congenital lung lesion resection. Patients were included if they were managed with either a 1.5% 2-chloroprocaine (Group C) (n = 26) or 0.1% ropivacaine (Group R) (n = 28) infusion administered through a caudally placed thoracic epidural catheter. The primary outcome was morphine administration at 0-24 h.ResultsPatients were similar in age, weight, length of stay, epidural location and duration. There was weak evidence for a difference in morphine use in the first 24 h in Group C compared to Group R (P = 0.08) but no difference 24-48 h. Group C was more commonly managed with ketorolac at 0-24 h (P = 0.03) and 24-48 h (P =< 0.01).DiscussionThe use of 2-chloroprocaine for continuous epidural infusion in infants following thoracotomy was not inferior to ropivacaine and there was weak evidence for a reduction in opioid consumption in the first 24 h postoperatively. However, the 2-chloroprocaine group was more likely to receive ketorolac.© 2015 John Wiley & Sons Ltd.
