Gaseous microemboli and hyperoxia.
A recent issue of JECT contained two articles on air bubbles in the cardiopulmonary bypass (CPB) circuit and an article on the routine use of hyperoxia during CPB (1–3). Interestingly, these two subjects are related in a way that perfusionists do not commonly associate. The article by Dickinson et al. (1) and the commentary by Willcox and Mitchell (2) suggested that gaseous emboli passing to th...
متن کاملThe intravenous intralipid tolerance test.
The half-life of an intravenously injected bolus of intralipid 20% was measured in normal rats in order to asess its relationship to reticuloendothelial system (RES) activity. Groups of animals were studied following various treatments, and the results compared to measurement of carbon clearance in similar groups. The RES effects of silica and C parvum were confirmed by the carbon clearance tes...
متن کاملIntralipid and the Immune system
OBJECTIVES: We developed a novel lipid formulation of nystatin suitable for parenteral administration, nystatin-intralipid (NYT-IL), with antifungal activity and reduced toxicity in mice. We investigated the pharmacokinetics, tissue distribution and immunomodulatory effect of NYT-IL in mice. METHODS: Nystatin levels in serum and organs were determined using HPLC after NYT-IL or nystatin adminis...
متن کاملMicroemboli Monitoring in Ischemic Stroke
The detection is made possible because of the acoustic impedance between microemboli and blood, which increases the ultrasound intensity. Microemboli are transient (<100ms), high intensity (> 3dB) and unidirectional signal which are accompanied by a characteristic click or chirp sound (Ringelstein, Droste et al. 1998). The origin of microemboli are usually from an atheromatous plaque in the car...
متن کاملECC Sources of Gaseous Microemboli
___________ _ We have tried to locate sources of gaseous microemboli during the ECC using a newly developed ultrasonic detector. The detector was calibrated with filters of known pore size and the recorder setting was kept constant at all times. We studied, at the oxygenator, the effect of low and high fill volume, refilling with or without air into the cardiotomy line, mechanical disturbance, ...
