DESCRIPTION Continuous display of arterial waveform is a useful adjunct in monitoring of complex surgical cases. The nondominant radial artery is the vessel of choice in the absence of peripheral vascular disease. A patient underwent an aortic valve replacement and coronary artery bypass grafts. On postoperative day 2, while cutting the dressing surrounding the radial artery 20-gauge BD insyte ...

OBJECTIVES This study sought to characterize the echocardiographic findings of patients presenting with intravascular hemolysis (IVH) due to suspected continuous-flow left ventricular assist device (LVAD) pump thrombosis. BACKGROUND LVAD patients who develop pump thrombosis often present with IVH. Echocardiography may be able to detect device dysfunction in this setting. METHODS Continuous-...

With the spread of clinical applications, interest in use high-flow nasal cannula, which warms and humidifies oxygen with help traditional has increased. Many international protocols on cannula therapy (HFNC) are available. This study was conducted to evaluate methods used pediatric services specify roles responsibilities nurses application HFNC, one these methods. Because responsible for monit...

cannula, a curette needle, and a hollow bevelled needle with an inner removable stylet. The shaving action of the cannula over the curette after it has engaged the pleura is the recommended technique of pleural biopsy. The Abrams' needle consists of two main concentric tubes:3 the outer hollow trocar has a deep notch proximal to the tip and the cutting action of the inner hollow tube as it is a...

We performed a prospective study of hospice in-patients requiring a syringe driver (SD), to determine the site duration and tolerability of metal butterfly needles compared to Teflon cannulae. Using patients as their own control, prescribed medications were divided equally between two SDs (Graseby MS16a), for delivery over 24 h. A butterfly infusion (Flosafer, 25 gauge) was connected to one SD ...

OBJECTIVE To determine whether lung volume changes and breathing pattern parameters differ among 3 devices for delivery of nasal continuous positive airway pressure (CPAP) in premature infants. METHODS Thirty-two premature infants receiving nasal CPAP for apnea or mild respiratory distress were enrolled. Birth weight was (mean +/- standard deviation) 1081 +/- 316 g, gestational age 29 +/- 2 w...

New Appliances £DIRmAH 707 in length, and at its distal end has a tapering mount 0-236 in. (6 mm.) in length. At its proximal end there is a female Luer lock fitting, which can be firmly attached to a Luer or Luer lock syringe (see photograph). Our technique of primary operative cholangiography follows very closely that of Schulenburg (1966). Two points are worth mentioning. Firstly, if the sup...

A 29-year-old patient with patent foramen ovale (PFO) and arteriovenous-malformation developed Eisenmenger’s syndrome with subsequent multiorgan failure. Percutaneous veno-arterial extracorporal life support was established via the groin (Fig. 1). Transoesophageal echocardiography revealed a malposition of the venous cannula in the PFO (Fig. 2). The position of the cannula was corrected immedia...

A 20-gauge cannula placed via an interscalene approach in the left brachial plexus sheath of a healthy 18-yr-old male was used inadvertently for injection of 20 ml of antibiotic solution, despite clear labelling of the cannula and painful protest from the patient. The patient suffered no neurological sequelae. The treatment, possible causes and steps to avoid similar incidents are described.

A 69-yr-old woman presented with dyspnea on exertion was found to have moderate-to-severe mitral regurgitation with moderate left ventricular dysfunction (estimated ejection fraction was 30%) and was scheduled for elective mitral valve repair. The patient had undergone uneventful coronary artery bypass graft surgery 7 months earlier. Her medical history was otherwise significant for hypertensio...
