简要总结
This prospective observational study investigates whether Perfusion Index PI and Pleth variability index PVI can predict hypotension following spinal anaesthesia in women undergoing elective caesarean section . In 132 parturients baseline and post spinal PI PVI and hemodynamic changes monitored . The study aims to estabilish PI and PVI as non invasive predictors of post spinal hypotension and correlate them with vasopressor requirement.
