Brief summary
Perioperative fluid management has been historically dictated by outdated, contradictory
concepts. Excessive or inadequate fluid administration around surgery is deleterious and
hence goal-directed fluid therapy using Oesophageal Doppler-derived cardiac indices is
preferable to optimize tissue perfusion. Previous studies in this area have been hampered by
lack of standardization in other aspects of perioperative care and none have explored the
impact of individualized fluid therapy on post-operative fatigue.The investigators proposed a
study involving 80 patients having open/ laparoscopic colonic surgery to investigate the
effect of Oesophageal Doppler guided fluid administration intraoperatively compared to
current best practice of fluid restriction. The investigators have an optimized
peri-operative care pathway established at the Manukau Surgical Centre (MSC), Middlemore
Hospital. All patients will be cared for under the Enhanced Recovery After Surgery (ERAS)
multimodal care plan therefore ensuring that all other aspects of care besides intraoperative
fluid administration remain homogenous. Outcomes will include post-operative recovery,
clinical outcomes as well as physiological data with follow-up to 30 days.
