Abstract

|
|
The need for a short-acting non-depolarizing neuromuscular blocking agent to replace succinylcholine chloride(succinylcholine) is recognized widely and attempts to find such a drug have been numerous.
Atracurium besylate(atracurium) is one of the new series of neuromuscular blocking agents with little cardiovascular effect and is not dependent on hepatic and renal function for terminating its action because of its self-destroying mechanism.
Because succinylchline may occasionally be contraindicated for intubation in parturients we studied the use of atracurium in 23 patients having cesarean section. All patients received 0.5mg/kg atracurium for intubation and neuromuscular
relaxation.
Hemodynamic changes, the time from the injection of atracurium to maximal twitch suppression, the time between atracurium administration and the return to 10% of control twitch height were recorded and observed the degree of vocal cord relaxation
and
conditions of intubation and evaluated the Apgar scores.
1) Mean arterial pressure and heart rate increased significantly after intubation compared with that of control and just before intubation but there were no significant changes in 5 minutes after intubation.
2) The 90% twitch suppression following atracurium administration was 75.6(20.9 seconds.
3) The return of 10% of control twitch height was 2449.3(1114.0 seconds.
4) Intubation conditions were excellent for 19 patients.
5) The Apgar scores of 20 neonates were high.
Theses data suggest that the use of atracurium may be a useful alternative for induction for Cesarean section when succinylcholine is contraindicated.
