Dr Edwards is an anaesthetist/perioperative physician and researcher at UHS. His clinical activities include anaesthesia for major adult surgery and preoperative optimisation. He leads service development within perioperative medicine as the clinical lead for preoperative assessment.

He completed his higher degree in perioperative immunology and postoperative morbidity at University College London before moving to Southampton in 2013. He now pursues his research interests in individualised perioperative fluid therapy, emergency surgery care and efficient trial designs. He is Chief Investigator of the NIHR-funded FLO-ELA (FLuid Optimisation in Emergency LAparotomy) and CAMELOT (Continuous rectus sheath Analgesia in Emergency LaparOTomy) trials, and Deputy Chief Investigator of the OPTIMISE II trial.

He is Deputy Directory of the RCoA UK Perioperative Medicine Clinical Trials Network and the regional lead for integrated academic training in anaesthesia and critical care.

Major grants:

  • Chief Investigator, CAMELOT trial (Continuous rectus sheath analgesia in emergency laparotomy) - £1.6m NIHR HTA funded June 2021

  • Chief Investigator, FLO-ELA trial (FLuid Optimisation in Emergency LAparotomy) - £1.2m NIHR HTA funded October 2016

  • Deputy Chief Investigator, OPTIMISE II trial (haemodynamic therapy in major gastrointestinal surgery) – £1m Edwards Lifescience / NIHR funded July 2016

  • Co-applicant, GAP trial (Gabapentin for acute pain in postsurgical patients) - £1.1m NIHR HTA funded May 2016

Impact example:

The FLO-ELA trial is a national exemplar of efficient and cost-effective data-enabled perioperative clinical trials. Definitive evidence on the effectiveness of individualised perioperative fluid therapy during emergency surgery will be delivered at a fraction of the per-patient costs of conventional trials. The model of outcomes data linkage to an existing anaesthesia-led national audit (National Emergency Laparotomy Audit) has since been replicated by other major UK perioperative trials (e.g. VITAL trial linked to the Perioperative Quality Improvement Project).
