Ability of pulse oximetry-derived indices to predict hypotension after spinal anesthesia for cesarean delivery: A systematic review and meta-analysis.

ABSTRACT: Cesarean deliveries are often performed under spinal anesthesia because of the reduced risk of complications compared with that of general anesthesia. However, hypotension frequently occurs and adversely affects both the mother and fetus. Indices, such as the perfusion index (PI) and pleth variability index (PVI), which are derived from pulse oximetry have been used in numerous studies to predict hypotension after spinal anesthesia. However, their predictive abilities remain controversial. This study aimed to investigate the ability of PI and PVI, measured before the initiation of spinal anesthesia, to predict hypotension after spinal anesthesia in patients undergoing cesarean deliveries. To this end, we conducted a systematic review and meta-analysis. We searched MEDLINE, Embase, Web of S
