We examined the long-term effects of octreotide, a somatostatin analogue, on ventilation in a case of cirrhotic hypoxemia. After daily administration of octreotide for one month, the dyspnea on exertion was notably ameliorated, although pulmonary gas exchange was only slightly improved. The octreotide therapy reduced the hypoxic ventilatory drive, which may be one reason for the relief of the dyspnea sensation.
