Prediction of preload dependency using phenylephrine-induced peripheral perfusion index during general anaesthesia: a prospective observational study.

Background: Tracking preload dependency non-invasively to maintain adequate tissue perfusion in the perioperative period can be challenging.The effect of phenylephrine on stroke volume is dependent upon preload. Changes in stroke volume induced by phenylephrine administration can be used to predict preload dependency.

[Two Cases of Large Gynecological Tumor Complicated by Preoperative Deep Vein Thromboembolism and Pulmonary Thromboembolism-Should We Use Inferior Vena Cava Filters ?-].

We experienced two cases of large gynecological tumor resection with co-existing deep vein thrombo- embolism (VTE) and pulmonary thromboembolism (PTE). Despite perioperative anticoagulation, one of the two patients developed dyspnea with massive PTE postoperatively, although the other patient did not have any postoperative complications. To prevent fatal mas- sive PTE, temporary inferior vena cava (IVC) filter might have been effective during perioperative period in these cases.

Wide discrepancies in activated clotting times measured by two devices were detected for a patient with lupus anticoagulant in a cardiac surgery.

Introduction:: For a patient with lupus anticoagulant (LA), activated coagulation time (ACT) was measured with two different types of devices (HEMOCHRON 801 and HEMOCHRON Jr).

Case Report:: ACTs during heparinization measured with the HEMOCHRON 801 were over the range of measurement, while those with the HEMOCHRON Jr. reflected an almost normal response to heparin.
