USCOM more accurate monitor than blood pressure in pregnancy

Tuesday 23rd of October 2012: Uscom (ASX code: UCM).

Uscom Ltd today announced publication in the British Journal of Anaesthesia of research from the Department of Anaesthesia and Intensive Care, and the Department of Obstetrics and Gynaecology at The Chinese University of Hong Kong in Hong Kong. The study demonstrated that USCOM was a more accurate method for monitoring circulation in term pregnant women than blood pressure, the current method.

The study looked at the effect of the pregnant uterus on the great vessels and circulation as patients lay on their back and then on their side, and found that USCOM detected changes in circulation that had only previously only been demonstrated using intra-arterial catheters, a method not considered for routine use due to its invasiveness. Blood pressure has therefore become the method for monitoring circulation in pregnancy. However in this study USCOM, a non-invasive method, was demonstrated to be as accurate as the invasive method and more accurate than the current method of blood pressure monitoring.

Executive Chairman of Uscom, Rob Phillips said, “Accurate monitoring of circulation in pregnancy is critical for the health of the mother and the foetus, and this study demonstrates that USCOM is more accurate than blood pressure for monitoring circulation during pregnancy. This research supports a wider role for USCOM in obstetric care.”
