Experience with the G-suit in 22 cases, nine of which are reported here, demonstrated its effectiveness in the control of intra-abdominal bleeding and in the restoration of effective blood pressure. Necessary examinations, insertion of catheters, etc, should be accomplished before the application of the G-suit. The immediate pressor response noted must be attributed to reduction of the volume of the vascular bed. Control of bleeding is felt to result from circumferential compression of the wall of the bleeding vessel. An abrupt fall in blood pressure can be anticipated upon the release of the pressure from the G-suit, and adequate volume replacement must precede or accompany deflation of the suit.
