RESUMO
It is important that the clinical anesthetist pay attention to the interaction of anesthetic induction agents and succinylcholine chloride(S,C,C) on the elctrolyte level especially the plasma potassium ion concentration. For instance succinylcholine chloride has a marked effect upon specific conditions such as severe burns, multiple injury, deabetes insipidus and myopathy. Also secondary plasma changes may bring about non synchronous depolarizing action on the muscle and cause cardiac arrhythmai and even cardiac arrest by the increase of potassium concentration in the plasma. With this in mind the author has randomly selected 30 patients who belong to class l physical status by the classification of the American Society of Anesthesiologist had no abnormal symptoms in respiration, circulation or endocrine and metabolism defects. This paper covers the period from the 10th of April 1979 to the 10th of May 1980 in the Department of Anesthesiology, Hanyang University Hospital. The 30 subjects were divided into 3 groups: a) propanidid with S.C.C. b) thiopental sodium with S.C.C. c) diazepam with S.C.C. The plasma concentration of potassium, sodium and calcium were observed and compared in the pre-induction (control group) and two minute post-induction(study group). The results are follows: 1) The plasma potassium ion concentration showed no any significant changes in the whole group. 2) The plasma sodium and calcium ion concentration also showed no any significant changes in the whole group.
