Abstract |
Ritodrine hydrochloride is widely used for the treatment of premature uterine contraction because the drug has beta2-sympathomimetic effect on the uterus. Hypokalemia is one of the most common side effects of ritodrine. We experienced a case of hyperkalemia without ECG change that occurred during cesarean section in a healthy parturient, associated with low-dose ritodrine pretreatment for six and half hours to stop preterm labor. We treated the patient with potassium-free fluid and calcium chloride. Plasma potassium level returned to normal four hours after the ritodrine had been terminated. |
Key Words:
