    Abstract:
    Adult respiratory distress syndrome has been reported after endoscopic variceal sclerotherapy with sodium morrhuate. It has been proposed that sclerosant entering the pulmonary circulation during intravariceal injections may cause pulmonary hypertension and capillary injury. The purpose of this study was to determine whether variceal sclerotherapy with sodium morrhuate causes capillary injury or pulmonary edema in humans. We studied the effect of sclerotherapy on gas exchange and pulmonary and systemic hemodynamics in 8 patients who required endoscopic variceal sclerotherapy for treatment of variceal hemorrhage. The pulmonary vascular resistance index increased from 246 +/- 67 dyn X s X cm-5/m2 (mean +/- SEM) at baseline to a high of 303 +/- 85 dyn X s X cm-5/m2 60 min after sclerotherapy (normal range 250-500 dyn X s X cm-5/m2). Pulmonary artery pressure remained stable while cardiac index decreased by 12% over the same period. There were also small increases in systemic vascular resistance index and systemic arterial pressure after sclerotherapy. Although there was no change in arterial oxygen tension, the alveolar-arterial oxygen difference improved after sclerotherapy. These results indicate that variceal sclerotherapy with sodium morrhuate is associated with clinically insignificant changes in pulmonary and systemic hemodynamics. We did not detect evidence of acute lung injury after sclerotherapy.
