Abstract
CH,COOCH,N(CH,), C1 I I CH,COOCH,N(CH,), ci Succinyl choline chloride is soluble in water, giving a clear, colourless solution, and is used in 5 % concentration for intravenous injection. It is rapidly destroyed in the body by plasma and erythrocytes, and in vitro by alkalies7. When given intravenously it produces neuro-muscular block by depolarisation of the myo-neural junction, and is hydrolysed by cholinesterasez. As the drug is carried by the blood to the various muscles, a wave of muscular contraction is followed by a period of profound relaxation. Experimentally, in frogs, succinyl choline chloride itself produced a contraction of the isolated nerve muscle preparation, which was counteracted by curare in concentrations adequate to counteract the effect of acetylcholine2. In cats, the previous injection of eserine intravenously markedly prolonged the paralysing effect of succinyl choline chloride, in contrast to eserine which antagonises the action of tubocurarine and has no effect on the block produced by decamethonium2. Succinyl choline chloride does not release histamine or produce bronchospasm. It has no effect on the cardio-vascular system2.
Succinyl choline chloride is a safe and effective anesthetic for preventing muscle spasm and preventing muscle injury in anesthesia.
