High portal venous blood flow (Qpv) may contribute to posthepatectomy liver failure. Both
Trendelenburg position (TP) and elevated airway pressure (Paw) increase backpressure to …

Background It has been suggested that blood loss during liver resection may be reduced if
central venous pressure (CVP) is kept at a low level. This can be achieved by changing …

Results Portal vein blood flow volumes were significantly lower in the left decubitus position
than in the supine. In the right hepatic artery, the left decubitus position gave significantly …

Purpose In order to assess the occurrence of blood congestion in the liver during liver
resection, we aimed to evaluate the influence of a positive-end-expiratory-pressure (PEEP) …

Positive end-expiratory pressure (PEEP) may impair extrapulmonary organ function.
However, the effects of PEEP on the liver are unclear. We tested the hypothesis that at a …

Background Bleeding remains an important intraoperative complication in patients who
undergo hepatectomy. It is generally believed that a reduction in central venous pressure …

Background Although low central venous pressure (CVP) has been used to minimize blood
loss during hepatectomy, the impact of variations of CVP on the rate of blood loss and on the …

Background/Aims: Patients with cirrhosis tend to have esophageal variceal bleeding
episodes at night, rather than during the day time. Since human beings carry on ordinary …

Objective Evaluation of the impact of end-expiratory pressure (PEEP) ventilation on venous
liver outflow, portal vein, and hepatic artery flows as well as systemic hemodynamics in …

We analyzed whether a compensatory increase of hepatic arterial (HA) flow, known as the
“hepatic arterial buffer response”(HABR), may serve for maintenance of liver blood supply …
