Right common femoral vein as a predictor of postspinal hypotension in patients undergoing cesarean section: A prospective observational study
Trina Sen, Biswajit Talukdar, Ananya Devi, Asif Ahmed, Sayantanee Roy, Faiza Ahmed TalukdarBackground and Aims:
Postspinal hypotension is a common occurrence during cesarean section (CS) due to autonomic blockade and inferior vena cava compression by the gravid uterus. The aim of this study was to assess the role of the right common femoral vein (RCFV) diameter measurement in predicting the occurrence of hypotension following spinal anesthesia during CS.
Materials and Methods:
Fifty-three patients with term singleton pregnancy were included. Preoperative measurements of the transverse diameter of RCFV and baseline hemodynamic parameters were taken. Changes in parameters were measured immediately after spinal anesthesia and at every 3 min interval till delivery of the baby. The primary outcome was the association between the diameter of RCFV and postspinal hypotension. Association of RCFV diameter and hypotension was identified by binomial logistic regression analysis.
Results:
A longer transverse diameter of RCFV was associated with the occurrence of postspinal hypotension (odds ratio: 6.390, (95% confidence interval: 2.47–16.48),
Conclusion:
A longer transverse diameter of RCFV was associated with hypotension and could identify parturients at major risk of hypotension following spinal anesthesia in CS.
