Randomized Controlled Trial Clinical Trial
[Effects of continuous epidural administration of fentanyl and morphine on postcesarean pain].
We studied the effects of continuous epidural administration of fentanyl and morphine with bupivacaine for management of postcesarean pain. Eighteen patients received either bolus epidural administration of fentanyl 100 micrograms or morphine 3 mg with 0.5% bupivacaine 4 ml, followed by continuous infusion of fentanyl 33 micrograms.ml-1 with 0.17% bupivacaine or morphine 0.21 mg.ml-1 with 0.17% bupivacaine for 48 hours, respectively. Pain score was assessed at 0 h, 12h, 24h and 48h after leaving the operating room. ⋯ In all cases pruritus was noted. Severe pruritus was observed in the morphine group significantly more than in the fentanyl group. The current results indicate that morphine may be preferable to fentanyl for postcesarean pain control using the present opioid doses.

A 26-yr-old morbidly obese parturient with a body mass index of 62 kg.m-2 underwent elective cesarean section for preeclampsia under epidural anesthesia. The distance between the skin and the epidural space was about 9 cm at the L3-4 interspace via mid approach. Epidural catheter was inserted 5 cm cephalad in the sitting position and a bolus of 17 ml of mepivacaine 1.5% was given in the supine position. ⋯ Both maternal and neonatal postpartum courses were uneventful. In conclusion, elective cesarean section in a morbidly obese parturient was successfully managed with epidural anesthesia. This indicates that an elective cesarean section under epidural anesthesia reduce the risk of perioperative complications in a morbidly obese parturient.

Fiberoptic bronchoscopy was performed on 11 children aged from 6 months to 3 years and weighing between 2.1 and 12.5 kg using the laryngeal mask airway (LMA). The LMA allows observation of subglottic stenosis which can not be seen under tracheal intubation. The smaller prototype of the fiberoptic bronchoscope whose diameter is 1.8mm has no provision for angulation at the tip. However, using the LMA as a guide it was easy to reach the subglottic stenosis even using this smaller bronchoscope.
