Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective study that would investigate the transcranial doppler (TCD) changes during the living donor liver transplantation and the association between the TCD changes and the post-transplant neurological complications.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

A single-arm trial involving 100 patients undergoing living donor liver transplantation; all will be examined using transcranial doppler to find out its predictive value on post-transplant neurological deficits.
Primary Study Purpose

SCREENING

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

TCD arm

All patients will be evaluated with TCD for prediction of the post-transplant neurological complications

Group Type EXPERIMENTAL

Transcranial Doppler

Intervention Type DIAGNOSTIC_TEST

Transcranial Doppler-derived parameters; pulsatility index (PI), resistance index (RI), mean flow velocity (Vmean) will be recorded before induction of anesthesia (T1).

After induction, TCD parameters, Hemodynamic variables including heart rate (HR), invasive mean arterial blood pressure (MAP), and central venous pressure (CVP) together with Arterial blood gases (ABG analysis with values of PH, PCO2, PO2, blood oxygen saturation SO2 and bicarbonate HCO3), end-tidal carbon dioxide (ETCO2) and body temperature will be recorded too. Just before skin incision (T2), at the end of anhepatic phase 5 minutes before reperfusion (T3), 5 minutes after reperfusion (T4) and at the end of surgery (T5).

Postoperatively at ICU, TCD parameters, Hemodynamic variables, and ABG will be obtained 24 hours postoperative (T6) and at discharge from ICU (T7).
