Effects of Additional Fentanyl to Epidural Bupivacaine for Post-Thoracotomy Pain in Neonates

• Evaluate the difference in amount of Intravenous nalbuphine required after thoracotomy for lung resection in patients receiving epidural bupivacaine + fentanyl versus patients receiving epidural bupivacaine. [ Time Frame: First 48 hours post-operatively ] [ Designated as safety issue: No ]
  

• 1. Determine in two treatment groups the difference in pain scores as measured by the CRIES pain scale ,the length of stay,the incidence of side effects (respiratory depression, bradypnea, bradycardia and urinary retention). [ Time Frame: 48 hours post-operatively ] [ Designated as safety issue: No ]
  

The purpose of this study is to evaluate the best pain medication to be infused in the epidural catheter. At CHOP, the medication infused in the epidural catheter following a chest operation in neonates is a local anesthetic (bupivacaine). However, even with this continuous infusion, neonates still require multiple doses of intravenous opioids (i.e. morphine) because of persistent or constant pain. The administration of intravenous opioids in neonates can have many side effects, such as respiratory depression (reduced breathing rate), sedation, urinary retention (inability to pass urine), itching, nausea and vomiting It has been well documented that by adding a small dose of any opioid to a local anesthetic given through an epidural catheter, the feeling of postoperative pain can be significantly improved in older children and in adults. It is not known whether the addition of an opioid to a local anesthetic is beneficial in neonates. In this study, we are comparing the standard local anesthetic (bupivacaine) with a combination of bupivacaine and a small dose of an opioid (fentanyl).

This is a randomized study and the type of medication given into the epidural catheter will be chosen on the day of the operation by a random drawing (like flipping a coin). Your child could receive one of the following:

1. bupivacaine 0.1%
2. bupivacaine 0.1% with fentanyl 2mcg/ml Neither you nor your doctors will know which arm of the study your child is in. In case of emergency, the pharmacy can tell your doctor what medication your child is receiving.
