HEMODYNAMIC-CHANGES DURING LAPAROSCOPIC CHOLECYSTECTOMY IN PATIENTS WITH HEART-DISEASE

Changes in the hemodynamics and urine output were investigated in 19 patients undergoing laparoscopic cholecystectomy, five of whom had heart disease with the New York Heart Association classification I (n = 1) and II (n=4). Systemic blood pressure, central venous pressure, pulmonary capillary wedge pressure and cardiac output did not significantly change during the procedure including the establishment of pneumoperitoneum. Urine output 30-60 min after starting the pneumoperitoneum was significantly lower in the patients with heart disease compared to the values before and in the initial phase (0-30 min), and also to the values before and during the procedure in the control group. One patient suffered temporary cardiac decompensation following laparoscopic cholecystectomy which prolonged his hospital stay to seven days. The remaining four patients with heart disease could be discharged on the third or fourth day postoperatively. It is concluded that laparoscopic cholecystectomy is feasible in patients with heart disease but attention should be paid to the possibility of oliguria during prolonged pneumoperitoneum.
