Pulmonary hypertension and right heart failure in patients with beta-thalassemia intermedia.

abstract：OBJECTIVE:We have shown that the administration of 0.8 mg/kg of morphine (M) to patients with COPD resulted in a 20% increase in the maximum oxygen consumption (Vo2max), but was associated with significant drowsiness and euphoria. The objective of the present study was to ascertain whether lower doses of M alone or in ...
