Hemodynamic changes during celioscopy: a study carried out using thoracic electric bioimpedance

In 18 women A.S.A. physical status 1, a noninvasive thoracic electrical bioimpedance method was used to evaluate haemodynamic changes during gynaecological laparoscopy. A significant decrease in cardiac index was observed after peritoneal insufflation, from 3.2 to 2.8 L.min-1.m-2 and returned to the...

Summary:In 18 women A.S.A. physical status 1, a noninvasive thoracic electrical bioimpedance method was used to evaluate haemodynamic changes during gynaecological laparoscopy. A significant decrease in cardiac index was observed after peritoneal insufflation, from 3.2 to 2.8 L.min-1.m-2 and returned to the initial values after ten minutes of Trendelenburg's position. Elevated intra-abdominal pressure was also associated with a significant increase in mean arterial pressure (from 68 to 88 mmHg) and systemic vascular resistance index (from 1620 to 2491 dyn.s.cm-5.m-2). However, values were not restored after peritoneal exsufflation: systemic vascular resistance index values remained 30 per cent higher than that before insufflation. Decreased venous return may account for the significant decrease in cardiac output but mechanical compression does not explain the persistent elevation of systemic vascular resistance.
