The effects of volume loading during epidural analgesia

Perioperative Continuous Monitoring of St-Segment Changes in Patients Undergoing Elective Caesarean Section

“…Sudden hypervolaemia in the presence of sympathetic block increases myocardial work and oxygen requirements [2]. Different volumes of fluid were used before surgery in the two studies: in our study, the extradural group received 1 litre and the spinal group 1.5 litre; in the earlier study, all patients received 2 litre i.v.…”

Development and validation of a prognostic model for postoperative hypotension in patients receiving epidural analgesia

“…[ 14 ] As such, it is possible that unlisted factors, such as postoperative fluid management and dermatomal coverage, could have played a role in the incidence of hypotension. [ 23 ] It must be noted that we included multiple exposures, including type of surgery, invasiveness, ASA score, and comorbidity, as potential predictors, but none of these remained in the final model.…”

Blood volume is normal after pre‐operative overnight fasting

“…This theoretical volume deficit is, at best, negligible. Importantly, it is far below the amounts of fluid normally substituted in the context of general or neuraxial anaesthesia (7, 26). All patients in our study rested in a supine position during the night, possibly mobilising peripheral oedema from the legs accumulated there during the day before.…”
