Probably every physician practicing emergency medicine has encountered tragic cases of cardio and cerebro- vascular events or even of sudden death in the toilet. room. The defecation act is a consequence of the voluntary straining, which raises the intra-abdominal and intro-thoracic pressures, chain of events known as the Valsalva maneuver. The Valsalva maneuver induces a sharp rise of intravenous, intra-arterial pressures and reduction of coronary flow velocity and cerebral blood flow (1, 2, 3).Different kinds of cardiac rhythm disturbances were found in the persons performing Valsalva maneuver. There is common agreement that the Valsalva maneuver adversely affects the cardio-vascular system and is the causative factor in the patients with the compromised cardio-vascular system of the defecation syncope and death. Therefore it is a routine practice in coronary care units to administer the laxatives and stool softeners hopefully to reduce the straining at defecation. Two recent studies which compare the length of straining in the sitting comparatively to the squatting defecation posture found that sitting defecation posture obligate at least twice more straining than the squatting posture (4, 5). Accordingly the reduction of the intensity and length of the Valsalva maneuver during defecation in the natural for the human being squatting posture may prevent many cardio-and-cerebro-vascular events (6). And now it is not merely theoretic advice, a new squatting device was designed and tailored for the sewage system of the Western world (see on the page: video-film of the new squatting device).
