Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The Perfusion Index (PI) is the ratio of pulsatile blood flow (arterial chamber) to non-pulsatile static blood flow (venous and capillaries) in a patient's peripheral tissue, such as the fingertip, toe, or earlobe. This can be obtained from a pulse oximeter. This is non-invasive and continuous monitoring.
The pulse variability index (PVI) represents changes in PI that occur during one or more complete respiratory cycles. PVI is found by calculating over PI changes. Allows evaluation of intravascular volume; and a higher PVI is associated with greater responsiveness to fluid volumes.
In our work; We will simultaneously observe PI and PVI changes in the lower and upper extremities in the study group patients. When we look at the previous studies; we see that the parameters (PI and PVI) that we will look at are evaluated with different combinations in our study group patients. When we look at these studies again; We saw that contradictory results were obtained for the same parameters.
In our study, patients will be verbally informed in detail about the study in the preoperative period and their consent will be obtained. While the patients are taken to the operating room and monitored, the saturation probe will be connected to the 2nd finger of the upper and lower extremities of the patients, and the PI and PVI values in both extremities will be measured simultaneously. PI and PVI values and vital values (SAB, MAP, HR, SPO2) in both extremities before spinal anesthesia; intraoperative SAP, MAP, HR, SPO2, ephedrine requirement, atropine requirement and PI and PVI values in both extremities will be recorded.
As a result; In our study, we aimed to observe simultaneous changes in PI and PVI in the lower and upper extremities in pregnant patients who will undergo cesarean section under spinal anesthesia, which is our study group.
