The use of transcranial Doppler pulsatility index to guide hyperosmolar therapy.
Management of intracranial hypertension is a major cornerstone of neurocritical care. Apart from traumatic brain injury, there are no clear guidelines for intracranial pressure (ICP) monitoring. The insertion of ICP monitors is an invasive procedure with inherent risks and could be contraindicated in case of severe coagulopathy. The transcranial Doppler (TCD) pulsatility index (PI) has emerged ...
متن کاملFetal umbilical artery Doppler pulsatility index and childhood neurocognitive outcome at 12 years
OBJECTIVE To determine whether an elevated fetal umbilical artery Doppler (UAD) pulsatility index (PI) at 28 weeks' gestation, in the absence of fetal growth restriction (FGR) and prematurity, is associated with adverse neurocognitive outcome in children aged 12 years. METHODS Prospective cohort study, comparing children with a normal fetal UAD PI (<90th centile) (n=110) and those with an ele...
متن کاملBasilar and middle cerebral artery reserve: a comparative study using transcranial Doppler and breath-holding techniques.
BACKGROUND AND PURPOSE A 1997 report suggests that the posterior circulation of the normal brain has diminished vasoreactivity compared with the anterior circulation. To further study this, we quantified and compared the vasodilatory capacities of the middle cerebral (MCA) and basilar artery (BA) territories in response to changes in PaCO(2), as indices of respective cerebrovascular reserve (CV...
متن کاملUterine artery doppler pulsatility index at 11-14 weeks in ART pregnancies with egg-donation
Objective Uterine artery Doppler studies with measurement of pulsatility index (UtPI) represent recognized predictors of placental insufficiency and preeclampsia. Mode of conception (MC) has not been shown to modify the PI of uterine arteries; however we are not aware of studies investigating egg donations (ED). We hypothesize that perfusion of uterine arteries evaluated with Doppler studies ma...
متن کاملSecond-trimester uterine artery Doppler pulsatility index and maternal serum PP13 as markers of pre-eclampsia.
OBJECTIVE To evaluate whether measurement of maternal serum PP13 at 22 to 24 weeks of gestation, alone or in combination with second-trimester biochemical markers or uterine artery pulsatility measured by Doppler velocimetry, is useful in predicting those women at risk of developing pre-eclampsia. STUDY DESIGN A nested case-control study of pre-eclampsia cases with controls matched for gestat...
