Background: The perfusion index serves as a valuable tool for evaluating perfusion dynamics and is currently under consideration as a non-invasive approach to identify the potential onset of hypotension after a subarachnoid block (SAB). The current study sought to investigate the relationship between baseline perfusion index in parturients and the extent of hypotension experienced during spinal anaesthesia for Caesarean delivery, as well as to determine if baseline perfusion index could serve as a predictor for this hypotension. Material and Methods: A group of 30 expectant mothers scheduled for elective caesarean delivery was chosen for the study. The perfusion index was assessed while the participants were in a supine position, utilising a designated pulse oximeter probe affixed to the left index finger of each parturient to maintain consistency in the recorded PI values. Maternal non-invasive blood pressure, heart rate, and perfusion index were documented at one-minute intervals from the time of spinal injection until delivery, followed by recordings at two-and-a-half-minute intervals until the conclusion of the surgical procedure. Results: The findings indicate a notable reduction in systolic arterial pressure (SAP) following spinal injection in parturients, regardless of whether they had high or low baseline pulse indices (PI). However, those with elevated baseline PI experienced more pronounced decreases in SAP at the 4, 5, and 6-minute marks post-injection compared to their counterparts with lower baseline PI. Parturients exhibited significant reductions in mean arterial pressure (MAP) following spinal injection, regardless of whether they had high or low baseline perfusion index (PI). Notably, those with elevated baseline PI experienced a more pronounced drop in MAP five minutes post-injection compared to their counterparts with lower baseline PI. Conclusion: The study found that baseline PI measured at the finger is associated with the extent of arterial pressure reduction during spinal anaesthesia for Caesarean delivery. A baseline PI cut-off point of 3.5 may serve as a useful indicator for identifying parturients who are at risk for hypotension in this context. [ABSTRACT FROM AUTHOR] |
