[Fenoterol (Partusisten)-associated lung edema. A case report].
The side effects of a beta 2-mimetic tocolytic therapy are of importance for anaesthesiologists who administer anaesthesia for obstetric operations, as our case report illustrates. In a healthy 28 year old pregnant woman during the 32nd week of pregnancy i.v. fenoterol was started because of premature labor. After two days severe respiratory failure developed and cesarean section was performed. The patient needed mechanical ventilation with positive endexpiratory pressure and high inspiratory oxygen concentrations (F1O2 greater than 0.7) for 5 days thereafter. The chest x-ray revealed a fluid lung. With artificial respiration and a consequent diuretic therapy with dopamine and furosemide (10 mg . h-1 continuously, negative water balance--5,000 ml on the 4th day) gas exchange improved and extubation was possible on the 6th postoperative day. After exclusion of cardiac or renal disease as well as aspiration of gastric content, the diagnosis of a fenoterol-associated pulmonary edema was thought probable. From the literature it is known that beta 2-mimetics can aggravate the increased water and sodium retention during pregnancy and cause pulmonary edema by an additional increase in pulmonary artery pressure. Therapy consists of adequate oxygenation and induction of diuresis with continuous furosemide and dopamine to achieve negative water balance. When administering anaesthesia to patients on tocolytic therapy positive water balance has to be avoided and great care must be directed to the postoperative gas exchange.
