Non-invasive Haemodynamic Monitoring to Predict Spinal Hypotension During Caesarian Section

Can Non-invasive Haemodynamic Monitoring With Clearsight(r) Predict Spinal Hypotension During Caesarian Section? A Prospective Observational Study

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.

Inclusion Criteria:

• third trimester pregnant women undergoing elective ceasarean section under spinal anesthesia

Exclusion Criteria:

• emergent ceasarean section
• eclampsia or pre-eclampsia
• undergoing anti-hypertensive treatment
• arythmia
