10 세미만 소아에서 Pancuronium 과 Ketamine 및 Thiopental 투여후 Succinylcholine 에 의한 혈청 전해질치의 변동

A small but significant rise in serum potassium level following succinylcholine administration has been observed in normal anesthetized patients. A dangerous increase in serum potassium concentrations after the administration of succinylcholine chloride has been reported in an increasing number of clinical conditions including burns, massive muscle trauma, tetanus and uremia. The hyperkalemia can be of sufficient degree to cause ventricular tachycardia and fibrillation. Serum electrolytes levels were measured in 40 healthy children during induction of anesthesia. They were less than 10 years old and were divided into 4 groups of 10 children each. Group I: Ketamine 2 mg/kg and succinylcholine 2 mg/kg Group II: Thiopental 5 mg/kg and succinylcholine 2 mg/kg Group III: Pretreatment with pancuronium 20 μg/kg followed in 3 min by ketamine 2 mg/kg and succinylcholine 2 mg/kg Group IV: Pretreatment with pancuronium 20 μg/kg followed in 3 min. by thiopental 5 mg/kg and succinylcholine 2 mg/kg. Venous blood samples for serum electrolyte estimation were obtained using a catheter placed in an antecubital vein. The following results were obtained: 1) Serum potassium concentration following administration of succinylcholine was significantly increased in group I (p
