Comparison of the Finapres blood pressure monitor with intra-arterial manometry during induction of anaesthesia.

Abstract:

:The Finapres (Ohmeda, Madison, U.S.A.) is a non-invasive device which continuously measures the arterial blood pressure in a finger and produces a real-time display of the arterial pressure wave. It consists of a finger cuff with an infra-red transmission plethysmograph, a servo control box and a monitor unit. The device was compared with intra-arterial pressure monitoring in twenty patients during induction of anaesthesia for elective neurosurgical procedures. The differences between the two methods were considerable, ranging from -40 mmHg to +26 mmHg for mean pressure. While the Finapres has potential as a non-invasive continuous blood pressure monitor, the current model Finapres, as supplied, displays too great a variability for it to be used as an alternative to intra-arterial pressure monitoring.

  • Epidural opioids in obstetrics--a review.

    abstract::Epidural opioids have been used in obstetrics since 1980. Various opioids are reviewed in relation to their pharmacology, their efficacy in labour, during caesarean section and for postoperative analgesia, their side-effects and safety. In this patient population it appears safe to administer epidural opioids on the g...
