Description of intervention(s) / exposure
Trauma patients admitted and undergoing surgical procedures will have their liver function assessed during admission to ascertain the development of liver disease, potentially resulting from exposure to volatile anaesthetic agents. VALDA occurs typically within days of exposure, and therefore patients will have repeat LFTs taken on admission, and then on days 1, 4, 8 and 12 postoperatively. Those with a characteristic pattern of dysfunction will be followed up with immunoassay, to confirm the development and presence of antibodies typically seen in immune-mediated liver dysfunction (anti-trifluoroactate [TFA] antibodies). Those with abnormal liver function will be followed up by a hepatologist.
Intervention code [1] 284424 0
Not applicable
Comparator / control treatment
Trauma patients admitted, but having no surgery, and
trauma patients undergoing surgery with no volatile exposure (TIVA or regional technique) will have their liver function assessed.
Control group
Active

Outcomes
Primary outcome [1] 286674 0
Incidence of liver disease attributable to volatile agent exposure, as determined by previously mentioned data. Patients with abnormal over function will be further for concomitant hepatotoxic medications and liver injury. Those suspicious of VALDA will have anti-TFA antibody screening to confirm it.
Timepoint [1] 286674 0
Development of VALDA within 12 days of exposure.
Secondary outcome [1] 296443 0
Incidence of liver disease in trauma patients, as determined by abnormal liver function tests.
Timepoint [1] 296443 0
Within twelve days of surgery.
