Rocuronium (Org 9426) for caesarean section.

This was a prospective, non-randomized, multicentre study of rocuronium (Org 9426) in 40 elective Caesarean section patients at full term without fetal distress. Anaesthesia was induced with thiopentone 4-6 mg kg-1 i.v. and rocuronium 0.6 mg kg-1 and maintained with isoflurane and nitrous oxide in oxygen. Monitors included ECG, arterial pressure, pulse oximeter and train-of-four (TOF) produced by ulnar nerve stimulation. In all patients, full neuromuscular block at the hand indicating the maximum effect of rocuronium (T1 = 0) occurred at a mean time of 98.1 (SE 9.4) s. However, after 79.3 (2.9) s, excellent to good intubating conditions were achieved in 90% of patients. Injection to delivery time was 12.7 (0.9) min and the surgical procedure lasted 53.1 (3.5) min. After administration of rocuronium, T2 appeared after 32.7 (1.8) min (indicating duration of effect). At the end of the surgical procedure in 39 patients, glycopyrronium 0.2 mg and neostigmine 1 mg were given every 5 min to antagonize residual neuromuscular effect. The mean dose of neostigmine required was 1.54 (0.1) mg. Rocuronium had no clinically significant effect on maternal heart rate or arterial pressure. After administration of thiopentone and rocuronium in two patients, temporary erythema occurred, one along the site of injection and the other on the chest wall. Rocuronium had no untoward effects on the neonates, evaluated by 1- and 5-min Apgar scores, time to sustained respiration, total and muscular neuroadaptive capacity scores, acid-base status and blood-gas tensions in umbilical arterial and venous blood.(ABSTRACT TRUNCATED AT 250 WORDS)

Fetal and maternal cardiovascular effects of atropine and glycopyrrolate.

This study compared the effects of intravenous atropine and glycopyrrolate on maternal and fetal heart rates and variability, maternal blood pressure, and uterine activity in 20 normal full-term parturients in labor. Group 1 (N = 10) received 0.005 mg/kg of glycopyrrolate, and group 2 (N = 10) received 0.01 mg/kg of atropine. There were no statistically significant changes in fetal heart rates or variability in either group. Uterine activity increased in a normal manner as labor progressed. Maternal heart rate increased significantly and essentially equally in all patients in both groups ranging from 15 to 78 beats/min and a mean (+/- SD) of 36 +/- 16 in group 1 and from 15 to 65 beats/min with a mean of 35 +/- 17 in group 2. There were no statistically significant changes in maternal blood pressure in either group.

Sympathoadrenal activity, maternal, fetal, and neonatal responses after epidural anesthesia in the preeclamptic patient.

This study confirms that preeclamptic patients have higher plasma levels of catecholamine than those of normal patients. It also demonstrates that epidural analgesia when administered to the preeclamptic patient during labor is followed by a significant reduction in the plasma levels of catecholamines without any adverse effects on maternal blood pressure, uterine activity, fetal heart rate, or the neonate.
