A 32 weeks pregnant female with preterm contractions treated with tocolytic agents. She fuher developed pulmonary edema. Which of the following tocolytic must have caused pulmonary edema in this patient?
Correct Answer: Ritodrine
Description: The infusion of beta-agonists (Ritodrine) has resulted in frequent and at times, serious and fatal side effects. Pulmonary edema is a special concern. Because beta-agonists cause retention of sodium and water, with time--usually 24 to 48 hours, these can cause volume overload. The cause of pulmonary edema is multifactorial, and risk factors include: Tocolytic therapy with beta-agonists Multifetal gestation Concurrent coicosteroid therapy Tocolysis for more than 24 hours Large intravenous crystalloid volume infusion Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y.
