Abstract
An elevation of intracranial pressure (ICP) secondary to cerebral oedema is a major contributor to morbidity and mortality in acute liver failure (ALF). We present a case of ICP monitoring with ocular ultrasonography in a 2-year-old child with ALF for liver transplantation. Since invasive ICP monitoring was risky considering the level of coagulopathy, optic nerve sheath diameter (ONSD) monitoring was done by ultrasound. A value of 4.5 mm was chosen as the cut-off for an ICP >20 mmHg in this child and was checked at regular intervals during the surgery. Ultrasonographic ONSD assessment can be a useful modality in liver transplant recipients, with severe coagulopathy and high ICP. In our specific patient scenario, ocular ultrasound proved to be a valuable safe and noninvasive monitoring tool in this paediatric patient.
