| Scientific title | A comparison of speed of action of phenylephrine and ephedrine |
| Study objectives | Does phenylephrine allow more rapid control of maternal arterial pressure during obstetric spinal anaesthesia than ephedrine? |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Pregnancy and Childbirth: Anaesthesia |
| Intervention | Phenylephrine vs ephedrine A standardised anaesthetic technique will be used. Maternal arterial pressure will be measured by an automated oscillometric device (Cardiocap II, Datex Instrumentarium) and by a continuous, non-invasive photoplethysmographic device using a finger probe (Finapres 2300, Ohmeda). Boluses of phenylephrine 100 ug or ephedrine 6 mg will be given whenever systolic arterial pressure falls by 15% from the prespinal value. An analog arterial pressure waveform will be recorded using a PowerLab 8sp recording and analysis device (AD Instruments Inc). This time from administration of vasopressor to time of peak effect on arterial pressure will then be analysed. |
