Investigation of the efficacy of PVI (Pleth Variability İndeks) monitorization on intraoperative fluid and blood transfusion, intraoperative hemodynamics in total hip surgeries.

Abstract

INTRODUCTION: We aimed to compare the effects of standard and PVI monitoring techniques on hemodynamic parameters, fluid and blood transfusion in patients who undergo total hip arthroplasty. METHODS: After the approval of the ethics committee, this study was conducted prospectively with 82 patients in ASA I-II groups who were 30-85 years of age and had undergone total hip prosthesis surgery. Patients in group 1 were monitored with PVI monitoring and patients in group 2 were only monitored with standard monitoring alongside anesthesia monitor. For the PVI monitored group, crystalloid+colloid+blood transfusion was done to patients in the PVI group with a target PVI value of 30% and > 1500 ml. RESULTS: When the pulse oximetry values of individuals in both groups were compared, there was significant difference between the groups. PVI measurements showed a decrease in time. The initial Hgb values of the patients in both groups were compared and significant differences were found. When total fluids given to the patients were compared significant differences found between the groups. Less fluid replacement was given to the PVI monitoring group. DISCUSSION AND CONCLUSION: Using noninvasive PVI monitoring is more practical, easier to use and causing no complications in comparison to standard monitoring. Nevertheless, further investigation on PVI monitoring are needed to illuminate the effectiveness of PVI monitoring on others parameters except for fluid management.
