Enhanced Recovery After Surgery (ERAS) is centred on patient
knowledge and involvement, and driven by a multi-disciplinary approach to reduce
the psychological and physiological stress of undergoing surgery. This is
achieved by providing pre-surgery education alongside a revision of traditional
surgical care practice, optimising all aspects such as pain relief, nutrition,
fluid therapy and early mobilisation.
The AERAS group conducts high quality research that informs clinical practice
and medical education both nationally and internationally. The group's goals

Major colorectal surgery is associated with considerable morbidity and a
prolonged recovery process. The Auckland Enhanced Recovery After Surgery Group
has improved clinical outcomes for patients undergoing major colonic resection
through the implementation of optimised perioperative care. The following are a
series of studies which pertain to this endeavour.

High vs low urine output targets in surgical patients: a randomised
assessor-blinded clinical trial
Lead Researcher: Dr Jevon Puckett
Fluid therapy is one of the most commonly prescribed medications in
peri-operative care. In current practise, extra fluid is often prescribed to
maintain the traditional urine output of 0.5ml/kg/hr. This trial aims to
question the relevance of this target in elective, healthy patients and to
evaluate the safety of a lower urine output target.

General surgeons are involved in the care of patients suffering from many
different diseases. These clinical situations provide many opportunities to
address a question with a scientific study with the aim of ultimately improving
patient care. This has been
achieved through a number of studies.

Enhanced recovery after surgery in elective hip and knee arthroplasty
Lead Researcher: Dr
Enhanced Recovery After Surgery (ERAS) protocols of standardised and optimised
patient care surrounding elective surgery have shown to be safe, cost effective
and demonstrate better health outcomes for patients. This study will evaluate
the implementation of an ERAS protocol for elective hip and knee joint
replacement at a surgical centre.
Acute appendicitis is a common surgical disease in children that can progress to
serious intra-abdominal infections. Surgical removal of the infected appendiceal
tissue forms part of the treatment but does not eliminate established infection
in the peritoneal cavity. The following studies look at how to improve clinical
care in acute appendicitis.
