简要总结

This study aimed to compare two cut-off values of plethysmographic variability index (PVI) -guided fluid therapy in patients undergoing supra-tentorial mass excision regarding immediate postoperative serum lactate.

详细描述

Fluid therapy in patients undergoing craniotomy is very critical; hypovolemia might decrease cerebral perfusion, while fluid overinfusion might cause brain swelling that impairs surgical removal of lesions.

The plethysmographic variability index (PVI) is one of the dynamic indices of fluid responsiveness, a simple, automatic, non-invasive, and continuous method based on calculating changes in the perfusion index (PI).

研究组 & 干预措施

Low PVI group

Experimental

Patients would receive the second round of fluid loading if the Plethysmographic Variability Index (PVI) was 14%.

干预措施: Fluid Therapy (Other)

High PVI gro

Experimental

Patients would receive the second round of fluid loading if the Plethysmographic Variability Index (PVI) was 20%.

干预措施: Fluid Therapy (Other)

结局指标
