To assess the value of using pleth variability index(PVI) to monitor the patient's intra-operative volume status continuously by observing the application of stroke volume variation(SVV) and PVI and their correlation in patients undergoing intestinal tumor surgeries.


Objective: To assess the value of using PVI to monitor the patient's intra-operative volume status continuously by observing the application of stroke volume variation(SVV) and pleth variability index(PVI) and their correlation in patients undergoing intestinal tumor surgeries.

Methods: 50 patients undergoing elective intestinal tumor surgery were enrolled, ASAⅠ-Ⅲ, aged 18-65 years. After the induction of general anesthesia, cardiac index(CI), cardiac output(CO), stroke volume variability(SVV), stroke volume index(SVI) were monitored with Vigileo system, while pleth variability index(PVI) and perfusion index(PI) were monitored with Massion Radical 7 system. During the surgery, goal directed fluid therapy was conducted according to the data of CI、SVI and SVV. Heart rate(HR), mean arterial pressure(MAP), central venous pressure(CVP), CO, CI, SVI, SVV, PI, PVI were recorded while after the induction of anesthesia(T1), making surgical incision(T2), performing intestinal anastomosis(T3) and closing the abdominal incision(T4). And we calculate the correlation of SVV and PVI using Pearson Correlation Analysis at different time points.

Medical and Biotech [MESH] Definitions

Continuous measurement of the movement and forces of blood in the CARDIOVASCULAR SYSTEM.

Physiologic or biochemical monitoring of the fetus. It is usually done during LABOR, OBSTETRIC and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery.

The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.

Measurement or recording of contraction activity of the uterine muscle. It is used to determine progress of LABOR, OBSTETRIC and assess status of pregnancy. It is also used in conjunction with FETAL MONITORING to determine fetal response to stress of maternal uterine contractions.

Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
