Brief Summary:
Spinal anesthesia SA is the most preferred method of anesthesia in cesarean deliveries because it eliminates the potential risks associated with airway management in pregnant women Spinal anesthesia poses a risk of hypotension with an incidence of approximately 70 resulting from decreased vascular tone due to sympathetic block Hypotension can cause dizziness in the mother nausea and vomiting and acidosis in the fetus Therefore the prevention and treatment of postspinal hypotension has been an important area of research in obstetric anesthesia
The Perfusion Index PI is the ratio of pulsatile blood flow arterial chamber to non-pulsatile static blood flow venous and capillaries in a patients 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
