Summary Respiratory function and hemodynamics were studied during laparoscopic cholecystectomy (LC) under a 10 mmHg pneumoperitoneum (PP) by carbon dioxide insufflation. Blood-gas analysis and measurement of cardiac function by using a Swan-Ganz catheter were performed. Creatinine clearance rate was measured preoperatively and intraoperatively. Compared with values obtained before the institution of PP, blood-gas analysis showed a significant increase in PCO2 (P〈0.01), and a significant decrease in pH (P〈0.01) and base excess (P〈0.05) during PP. With respect to cardiac function, there was no significant change in cardiac output, pulmonary arterial pressure, and pulmonary arterial wedge pressure. Intraoperative creatinine clearance rate (Ccr) was decreased in 29 of 48 cases, increased in 18 cases, and unchanged in 1 case, resulting in no significant difference overall between the values measured preoperatively and intraoperatively. However, in eight individual cases, the Ccr was found to have decreased significantly. Although alterations in respiratory function were observed, LC at 10 mmHg PP did not cause any crucial problems in respiratory or cardiac function. It should be kept in mind, however, that renal blood flow may decrease in some cases even at intraabdominal pressures under 10 mmHg.
