Perioperative Assessment of Right Ventricular Function and Venous Return in Patients With Epithelial Ovarian Cancer Undergoing Cytoreductive Surgery (Gyn Right) - Pilot Study

Withdrawn
Conditions
Right Ventricular Function and Venous Return
Registration Number
NCT02291276
Lead Sponsor
Charite University, Berlin, Germany
Brief Summary

In this prospective, observational study the investigators assess the perioperative course of right ventricular function in combination with the venous return in patients undergoing major non-cardiac surgery. The study aims to investigate if patients undergoing major non-cardiac surgery develop an impairment of right ventricular function and/or venous return. Furthermore, the study evaluates if an impairment of right ventricular function and/or venous return is associated to left ventricular function, arterial side of the circulation and to postoperative clinical outcome.

Primary Outcome Measures
NameTimeMethod
Venous returnUp to the first postoperative day

Venous return will be assessed perioperatively by venous return pressure gradient (dVR)

Right ventricular functionUp to the first postoperative day

Right ventricular function will be measured perioperatively by a combination of right ventricular stroke volume, tricuspid annular plane systolic excursion (TAPSE), hepatic venous blood flow, variations in diameter of vena cavae, and right ventricle/left ventricle-ratio.

Secondary Outcome Measures
NameTimeMethod
Organ complicationsParticipants will be followed up until hospital discharge, an average of two weeks

Postoperative organ complications are classified according to Clavien - Dindo classification

Immunological parameterUp to the third postoperative day

Perioperative immunological (IL-6 und TNF-alpha)

Endothelial parameterUp to the third postoperative day

Perioperative endothelial Parameter (ICAM-1)

Microvascular functionUp to the first postoperative day

Perioperative course of variables assessing microvascular function

Functional statusBaseline and hospital discharge with an expected average stay of 14 days

Measured by the Barthel activities of daily living (ADL) index and activities of daily living (IADL).

Hospital length of stayParticipants will be followed up until hospital discharge, an average of two weeks
Variables of transthoracic and transesophageal echocardiographyUp to the first postoperative day

Perioperative course of variables of transthoracic and transesophageal echocardiography

Postoperative painUp to the third postoperative day

Postoperative pain will be measured by Numeric Rating Scale - Visualized (NRS-V), the Faces Pain Scale - Revised (FPS-R), the Behavioral Pain Scale (BPS) or the Behavioral Pain Scale for Non-Intubated (BPS-NI)

Hemodynamic variablesUp to the third postoperative day

Hemodynamic variables are assessed by the anesthesia monitor and esophageal Doppler Monitor

Catecholamine administrationUp to the third postoperative day

Catecholamine administration intra- und postoperative
