Intrathoracic pressure as a tourniquet technic to tamponade bleeding esophageal varices.
The authors' report observations on 79 cases of esophagovariceal bleeding in which ten cases were subjected to an intrathoracic tourniquet maneuver of increasing intrathoracic pressure. All esophagovariceal bleeding ceased following the maneuver. An established maneuver safety limit (holding mean transmural CVP to no higher than 4.0 cm H2O) insured cardiac output maintenance and guaranteed against maneuver-generated morbidity. The authors conclude the cessation of the bleeding from esophageal varices observed is the combined result of tourniquet-tamponade by direct venous air compression on the bleeding varices as well as general esophageal compression.
