Superselective ophthalmic artery injection of the chemotherapeutic agent is a new treatment option for advanced retinoblastoma.[1] We present case severe bronchospasm with loss tidal volume and oxygen desaturation in an infant during catheterization under general anesthesia.

The water soluble benzodiazepine derivative, midazolam, is used almost exclusively at our institution to produce sedation for numerous surgical procedures. Mild arterial oxygen desaturation has been reported in patients who have received as little as .04 mg/kg. A time series design study was undertaken to determine if there was any correlation between the decline in arterial oxygen percent satu...

It is possible to inject highly supersaturated aqueous solutions of gas through a small capillary into an aqueous environment without the formation of significant gas bubbles. Such a technique has considerable potential therapeutic value in the treatment, for example, of heart attacks and strokes. The present paper is the second in a series (see Brereton et al. [1]) investigating the basic phen...

To investigate the ignition characteristics of an axial-flow injection burner for a Stirling engine, combustion chamber was designed. Diesel used as fuel and oxygen oxidant. The experiments were carried out with electric plug igniter. under different pressure, pre-oxygen supply time, flow position studied. experimental results show that, increase time increases gradually, success rate decreases...

To assess the effects of i.v. injection of morphine, 0.5 mg/kg, hemodynamic studies were performed on 24 critically ill patients under controlled ventilation. An esophageal balloon was used to estimate intrapleural pressure and transmural cardiac filling pressures were calculated. After injection of morphine, there were significant decreases in heart rate (13%), cardiac index (18%), stroke inde...

The microbial reduction of sulfate to hydrogen sulfide causes sewer pipe corrosion, one of the major issues in the water infrastructure [1]. Oxygen injection is presently considered as an attractive option for sulfide abatement in sewer systems. Oxygen can both inhibit the activity of sulfate reducing bacteria (SRB) and oxidize the sulfide that has been produced [2]. It is less expensive than m...

We have developed an injectable foam suspension containing self-assembling, lipid-based microparticles encapsulating a core of pure oxygen gas for intravenous injection. Prototype suspensions were manufactured to contain between 50 and 90 ml of oxygen gas per deciliter of suspension. Particle size was polydisperse, with a mean particle diameter between 2 and 4 μm. When mixed with human blood ex...

abstract aim and background:   this study is aimed to assess the effect of aminophylline (1mg/kg) on reversal of the sedative effects of propofol and the recovery time in patients under propofol anesthesia. due to the known effects of aminophylline on myocardial contractility and the increase in cardiac output, its effects on hemodynamic changes of propofol are also assessed. methods and materi...
