title: [Oral All-transretinoic acid administration in intubated patients with acute promyelocytic leukemia].
abstract: In acute promyelocytic leukemia (APL), disseminated intravascular coagulation is frequently observed. Massive alveolar bleeding can lead to respiratory insufficiency, requiring tracheal intubation and mechanical ventilation. Today all-transretinoic acid (ATRA) is part of induction chemotherapy in acute promyelocytic leukemia. The administration of ATRA is oral. No intravenously administered form is available. ATRA can be administered to intubated patients in the following manner: the daily amount of ATRA is placed in a sterile 50 ml tube. After addition of about 20 ml of sterile water the tube is heated in a waterbath to a temperature of 37 degrees C until the capsules melt and the suspension is completely liquid. The resulting oily fluid is then administered via nasogastric tube. We have treated 2 patients with acute promyelocytic leukemia intubated due to massive alveolar bleeding in this manner, and have observed a differentiation of promyelocytes to granulocytes and complete remission in both patients, indicating that the ATRA administered had been resorbed intestinally.
