Development of Advanced Double Intravenous Vasopressor Automated (ADIVA) System

• Status: Recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

Maternal hypotension during spinal anaesthesia for Caesarean delivery may bring various adverse effects. It is therefore important to closely monitor hypotension during spinal anaesthesia, however current technology does not allow the blood pressure monitoring to respond in timely manner should there be any occurrence of hypotension. The investigators developed an advanced double-intravenous vasopressor automated system (ADIVA) so as to tackle this issue via novel algorithm to control blood pressure more rigorously with more stable haemodynamic profiles.
