OBJECTIVE When the right atrium (RA) cannula is connected to the venous return line of the cardiopulmonary bypass (CPB) circuit, air is often introduced. Air in the venous cannula may increase cerebral air embolization at initiation of CPB despite the arterial line filter. We measured the volume of air present in the venous cannula after cannulation of the RA. Transcranial Doppler quantified em...

L eft ventricular assist devices (LVADs) are an established treatment for patients with end-stage heart failure as either a bridge to cardiac transplantation 1 or as lifelong support, also known as destination therapy.) is a continuous flow device that was approved by the US Food and Drug Administration in 2008, after a pivotal trial in 133 patients awaiting transplantation. 3 More patients hav...

BACKGROUND Some medical equipment manufacturers and surgeons have asserted that certain types of cannulas and other components of liposuction systems enhance the efficiency of fat aspiration. OBJECTIVE A laboratory experiment was designed to evaluate the effect of each component of a standard liposuction system on the rate of fat aspiration. A clinical investigation of the effectiveness of a ...

I read the recent article by Garg,(1) in which the author described the use of a spinal needle stylet to replace a faulty intravenous cannula. The technique is useful; however, there are some concerns. We have tried the stylet of a 26-G spinal needle for the exchange of a 24-G cannula in ten paediatric patients and have the following observations to make. The exchange was successful in only one...

The secure and haemostatic implantation of the left ventricular assist device (LVAD) apex inflow cannula can sometimes be challenging, especially in the setting of an acute myocardial infarction or significant ventricular wall thinning, when the myocardial tissue may be friable and tissue strength may be compromised. In these cases, surgical complications from this site may present a challenge....

BACKGROUND Nasal noninvasive ventilation (NIV) is a common form of noninvasive respiratory mode used in newborn infants. A next-generation nasal cannula (Neotech RAM cannula) has recently been used to provide nasal NIV. The impact of the Neotech RAM cannula on the delivery of pressure needs to be studied. METHODS In this ex vivo experimental design, a lung simulator (IngMar ASL 5000, version ...

A rigid-type of polyethylene T-cannula was fitted into the anterior ileum of six horses in order to improve the cannulation techniques. A piece of polyethylene net was fastened onto the intestinal wall around the cannula to prevent dislodgment of the cannula by promoting a secure adhesion between the ileum and the abdominal wall. The cannula barrel sheathed with silicone tubing was exteriorized...

A choroidal detachment may form during pars plana vitrectomy when the infusion line is partially disinserted and fluid is infused into the choroid or suprachoroidal space instead of into the vitreous cavity. We describe a new surgical technique that was used successfully in 4 patients who developed intraoperative choroidal detachments during 23-gauge vitrectomy after the infusion cannula was ac...

OBJECTIVES Tracheal intubation of ICU patients is frequently associated with severe hypoxemia. Although noninvasive ventilation reduces desaturation during intubation of severely hypoxemic patients, it does not allow for per-procedure oxygenation and has not been evaluated in mild-to-moderate hypoxemic patients for whom high-flow nasal cannula oxygen may be an alternative. We sought to compare ...
