Abstract
The aim of this work was to find out if injection sclerotherapy for esophageal varices was associated with any measurable deterioration in pulmonary function and blood gases, and any changes that may occur in circulating platelets and leucocyte concentrations after sclerotherapy. The results indicate that despite the generally agreed safety of routine upper gastrointestinal endoscopy and injection sclerotherapy concomitant arterial oxygen desaturation and decrease in pulmonary function appears to be relatively. Blood gases and pulmonary function tests may be impaired in cirrhotic patients because of hepatopulmonary syndrome. In patients with associated chronic pulmonary or heart disease who may be already hypoxemic, oxygen therapy is recommended when they undergo sclerotherapy. Patients with Pugh child B and C are preferable to use oxygen therapy during and after injection. (Author / FT).
