Brief Summary:
Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver diseases. Although with continuous advancement in technology, it remains a high-risk operation. The goal of LT is not only ensure survival of the patients but also to restore them back to their pre-morbid state with a good quality of life. Neurological sequelae can have major impact on postoperative outcomes after LT and yet the reported literature is scarce. Studies from Western countries showed some evidence on the use of cerebral oximtery in cardiac surgery to prevent neurological mishaps. LT shares similar intra-operative fluctuation of the haemodynamices as in cardiac surgery, causing disturbances in regional cerebral oxygenation and theorectically cerebral oximetry should be of great value as well in LT surgery. Data from a large randomised controlled trial is lacking from the current literatures. We therefore propose a prospective randomized controlled trial on the use of this device in adult LT and see whether its use could reduce neurological mishaps.

Arm Intervention/treatment
Active Comparator: Control
Patients undergoing liver transplantation without regional cerebral oxygenation monitoring using a cerebral oximeter.
Other: Cerebral oximeter
Near infra-red spectroscopy, NIRS

Active Comparator: Intervention
Patients undergoing liver transplantation with regional cerebral oxygenation monitoring using a cerebral oximeter.
Other: Cerebral oximeter
Near infra-red spectroscopy, NIRS

Primary Outcome Measures :
  1. Duration of confusion as assessed by the Confusion Assessment method [ Time Frame: 48 hours after liver transplant ]
    To assess patients experience of development of delirium

Secondary Outcome Measures :
  1. The time taken for MOCA to return to baseline [ Time Frame: 10 days after liver transplant ]
    To assess the time patients required to return health conditions within 10 days after surgery

  2. Other complications unrelated to neurological deficit according to Clavien-Dino Classification. [ Time Frame: 2 years ]
    To monitor any other complications developed by patients after liver transplant
