 For higher risk of regurgitation and aspiration rapid sequence induction into the general anesthesia is the method of choice for Cesarean section for more than last forty years 1. This means that intubation in apnoeic pause should be performed as soon as possible after administration of anesthetics and muscle relaxant. The traditional basic requirements on the administered muscle relaxant then primarily are a time of onset of its action and a creation of good intubating conditions. The depolarizing agent succinylcholine 1 to 1.5 mgkg is still worldwide recommended the muscle relaxant of choice for most parturients undergoing rapid-sequence induction for general anesthesia as provides adequate intubating conditions within approximately 45 seconds of intravenous administration 2. But essential likewise is, that administration of muscle relaxant does not affect only the creation of intubating conditions, but the effect on relaxation of the abdominal wall muscles has an effect also on surgical conditions for fetus delivery. Surprisingly, and to our knowledge, this effect has not been studied yet. From this perspective, and taking into account the negative effects of succinylcholine, rocuronium seems to be preferable alternative. Rocuronium in the dose of 0.6 mgkg in pregnant women induces good intubating conditions similar to succinylcholine 1, 3, 4, in a still reasonable time for apnoeic intubation 5. But compare to succinylcholine, which allows only very short muscle blockade and may thus prolong a delivery in complicated cases with all the consequences on postnatal fetus adaptation, rocuronium induces deep muscle relaxation and so should offer better surgical conditions for easier and faster fetus delivery.
