Surveillance hémodynamique non invasive dans la cœlioscopie gynécologique

摘要: A new non-invasive haemodynamic monitoring technique was investigated on twenty female patients submitted to gynaecological laparoscopy under general anaesthesia. Continuous aortic output measured with an echo-Doppler oesophageal probe specially developed by the authors. Peritoneal insufflation performed average of 4±0.750 1 CO2 at rate 0.666 · min−1; intraperitoneal pressure increased 11.57±1.60 mmHg during insufflation. Aortic changes were related in patient's position. In initial horizontal dorsal decubitus position, 2.83±0.642 min−1. Trendelenburg position (28±2°) induced a transient 9.54 % increase (p <0.05), while return marked 11.3 <0.01) output. No significant change observed and exsufflation (−2.13 −5.3 respectively). Mean arterial rose 16.4 after (initial values : 90±15.08 mmHg; p<0.01). Total vascular systemic resistances significantly higher end (2.999±376 dyn cm s−5; + 18.04 %; p <0.05). Heart did not significantly. this non-invasive, easy-to-handle enabled early detection laparoscopy. These frequently preceded blood or heart variations.
