Hypotension, Pregnancy Related, Spinal Anesthetics Causing Adverse Effects in Therapeutic Use
Conditions
Brief summary
Spinal anaesthesia for elective caesarean section is associated with maternal hypotension, secondary to alteration of sympathetic tone and hypovolemia, in up to 70% of cases. Our objective, in this prospective single-centre observational study, was to assess the ability of change in systolic ejection volume after 45° passive leg raising to predict hypotension after spinal anaesthesia. Systolic ejection volum was monitored with non-invasive Clearsight Device just before elective caesarean section in third trimester pregnant women.
Interventions
DEVICEClearsight monitoring
Non invasive hemodynamic monitoring using a finger cuff Cardiac ultrasound performed to calculate Velocity - Time - integral (VTI) Both intervention are performed before and after a passive leg raising challenge.
