Background:
We examined the effects of lumbar epidural morphine for postoperative analgesia in children after the Nuss procedure for funnel chest.
Methods:
An epidural catheter was inserted from the L 3-4 interspace preoperatively (epidural group). Epidural morphine 30 microg x kg(-1) was given at the beginning of the operation. Postoperatively, epidural morphine 3 microg x kg(-1) x hr(-1) was infused. The frequency of demand for postoperative analgesia was retrospectively compared with that of children who had not received epidural morphine (control group).
Results:
On the 0th postoperative day, the epidural group required fewer analgesics than the control group (0.50+/-0.30 vs. 2.50+/-1.00 x day(-1)). However, after the 1st postoperative day, the demand for analgesia did not differ between the two groups.
Conclusions:
Epidural morphine 30 microg x kg(-1) given at the beginning of operation provided effective analgesia on the 0th postoperative day after the Nuss procedure. However, epidural infusion of morphine 3 microg x kg(-1) x hr(-1) was not effective after the 1st postoperative day. Further study is needed to determine the lumbar epidural infusion dose of morphine adequate for use after the Nuss procedure.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
