BackgroundHypotension during major surgery is frequent, resulting in increased need for observation in the post-anaesthesia care unit and treatment including vasopressors and fluids. However, although severe hypotension in the immediate post-operative recovery phase after major surgery is suggested to be related to increased morbidity and mortality, the underlying risk factors are not well described, hindering advancements in prevention and treatment.MethodsWe performed a retrospective study assessing factors (age, gender, body-mass index, cardiac co-morbidity, haemoglobin, absolute and increase in c-reactive protein on the first post-operative day, bleeding, fluid balance at the end of surgery and the first post-operative day) related to severe persistent hypotension (SPH) (SPH: need for noradrenaline to maintain a mean arterial blood pressure (MAP) >65.0 mm Hg on the morning after surgery) and occurrence of other early (24 hours) complications. One hundred patients undergoing pancreaticoduodenectomy (PD) with pre-operative high-dose glucocorticoid and goal-directed fluid therapy were enrolled and perioperative data collected from anaesthetic and medical records.ResultsForty-five patients had SPH, who had a significantly higher increase in CRP levels the morning after surgery (median 50 mg L-1 vs 41 mg L-1 , SPH vs non-SPH, respectively, P = .028), and a significantly more positive fluid balance at discharge (median 1457 ml vs 1031 ml, respectively, P = .027) vs patients without SPH.ConclusionsSevere persistent hypotension after PD was associated with significantly increased inflammatory response and increased need for fluids. Future studies should investigate the effect of further inflammatory control in PD to improve haemodynamics and morbidity.© 2019 The Acta Anaesthesiologica Scandinavica Foundation.
