Re: cord pH and "birth asphyxia"From: timothy fitzpatrick (tfitzob@massmed.org)Fri Aug 30 17:08:11 1996

If the babe comes out very depressed it is helpful to have both venous and arterial samples of umbillical blood. The neonatologist say an early ultrasound of the fetal brain looking for flow in the middle cerebral arteries is a good early indicator(swelling and edema from a recent hypoxic insultÞcreased flow). Also good early fetal urine output without red cells or hematuria argue against a recent event. CT and MRI have a role in that hypoxic changes take some time to show up and a normal CT at day 2 or 3 argues against a peripartum event. .. "Dr. Tim" Timothy Fitzpatrick MBBCH Springfield Ma USA

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
