Alterations of the left atrial/right atrial pressure gradient were determined using a Swan-Ganz thermodilution catheter in 20 patients who underwent laparoscopic cholecystectomy with 12 mmHg pneumoperitoneum (LAP) and 13 patients who underwent minilaparotomy cholecystectomy (MINI). Right and left atrial pressures were both elevated by pneumoperitoneum. A diminished or reversed left/right interatrial pressure gradient was recognized during pneumoperitoneum in 4 of the 20 patients (20%) in the LAP group, whereas it was not recognized during operation in any of the 13 patients in the MINI group. Evaluation of the elevation of intrathoracic pressure during pneumoperitoneum using peak inspiratory airway pressure or pulmonary arterial pressure could not predict the occurrence of this paradoxical interatrial pressure gradient.: 1996 by the Société Internationale de Chir, ugie Iwase Kazuhiro First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut Kamiike Wataru First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut Uchikoshi Fumihiro First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut Takenaka Hiroaki Department of Surgery, Kinan General Hospital, 510 Minato, Tanabe, Wakayama 646, Japan, JP aut Miyata Masahiko First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut Matsuda Hikaru First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut https://doi.org/10.1007/s002689900036 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s002689900036 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Iwase Kazuhiro First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut NATIONALLICENCE 700 1- Kamiike Wataru First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut NATIONALLICENCE 700 1- Uchikoshi Fumihiro First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut NATIONALLICENCE 700 1- Takenaka Hiroaki Department of Surgery, Kinan General Hospital, 510 Minato, Tanabe, Wakayama 646, Japan, JP aut NATIONALLICENCE 700 1- Miyata Masahiko First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut NATIONALLICENCE 700 1- Matsuda Hikaru First Department of Surgery, Osaka University, Medical School 2-2 Yamadaoka, Suita, Osaka 565, Japan, JP aut Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
