Restricted Intraoperative Fluid Management Impacts Bowel Function Recovery

ObjectiveTo investigate whether restricted intraoperative fluid management impacts bowel function by using stroke volume variation as an index of volume administration in bowel surgeries.Methodseighteen patients undergoing elective bowel surgery were randomly divided into 2 groups,nine patients each.Group A:control the target of stroke volume variation maintaining at 10;Group B:control the target of stroke volume variation maintaining at 6.Edwards Flotrac sensor and Edwards Vigileo monitor was used to offer parameter of stroke volume variation(SVV) continuously.The other parameters such as arterial blood pressure,central venous pressure were also measured.All patients received general anaesthesia,tracheal intubation and mechanical ventilation,maintaining the peak pressure of airway at 20cm H₂O.Then according to the SVV value,adjust the target SVV of group A at 10,while group B at 6.The primary clinical outcome:the time of passing gas;the total amount of intraoperative fluid transfusion.The secondary outcomes:duration of surgery,blood loss,urine output,hemodynamic monitoring results,complications.Results The total amount of intraoperative intravenous fluid in group A is significantly less than in group B(P<0.05 ),Urine output in group B is more than in group A(P >0.05 ),The time of passing gas in group A is earlier than in group B(P>0.05).ConclusionStroke volume variation measured by Edwards Flotrac sensor and Edwards Vigileo monitor can be a useful parameter as an index of intraoperative volume administration.Restricted intraoperative fluid management enhanced bowel function recovery by using stroke volume variation as an index of volume administration in bowel surgeries.
