Ritodrine-associated Noncardiogenic Pulmonary Edema Diagnosed by Point-of-care Ultrasound: A Case Report of Twin Gestation.

ABSTRACT: Ritodrine hydrochloride, a beta-adrenergic tocolytic agent, can rarely cause acute noncardiogenic pulmonary edema, particularly in patients with multiple gestations or comorbidities. We report a case of a 28-year-old woman with twin pregnancy, type 1 diabetes, and hyperthyroidism that developed acute respiratory distress following ritodrine infusion. Imaging showed pulmonary edema, and point-of-care ultrasound (POCUS) revealed diffuse bilateral B-lines, preserved left ventricular function, and no signs of right heart strain or inferior vena cava plethora. These findings supported a diagnosis of noncardiogenic pulmonary edema. Emergency cesarean section was performed at 31^+6/7 weeks. Postoperatively, the patient's respiratory status improved, and both neonates had favorable outco
