Correlation between Perfusion Index and Hypotension Following Spinal Anesthesia during Cesarean Section

Abstract

Objective:  To explore the predictive strength of baseline Perfusion index (PI) for hypotension during cesarean sections (CS). This study was designed to analyze the relationship between baseline PI >3.5 and the number of episodes of hypotension during cesarean section in spinal anesthesia.

Material & Methods:  This correlational study was conducted at the Department of Anesthesiology, Lahore General Hospital. A sample of 65 primigravida women planned for elective CS were included in this study after informed consent. The procedure was performed as per the standard protocol of the hospital. Main variables like PI, mean arterial pressure, systolic blood pressure, and number of episodes of hypotension during surgery were recorded.

Conclusion:  In conclusion, this study demonstrates a significant association between baseline PI and the development of hypotension during CS under spinal anesthesia. Patients with a baseline PI >3.5 are at notably higher risk of hypotension.
