BACKGROUND The use of a double lumen cannula for veno-venous extracorporeal membrane oxygenation (v.v. ECMO) offers several advantages such as cannulation with only one cannula, patient comfort and the earlier mobilization and physiotherapy. The cannulation should be performed under visual wire and cannula placement into the right atrium, which is associated with risks of malposition and right ...

in the present study, we have investigated the effects of silymarine on depression and the possible role of serotonergic system in these effects. the rats were anesthetized intraperitoneally with ketamine hydrochloride and placed in a stoelting stereotaxic instrument. a stainless steel guide cannula (22-gauge) was implanted in the third ventricular region. the third ventricular region was infus...

Vacuum-assisted venous drainage (VAVD) is frequently used to increase venous return through smaller venous cannula and reduced venous line size. The purpose of this study is to determine the maximal flow rates achieved through various venous cannula with varying amounts of negative pressure applied during VAVD. The first test circuit consisted of 25 different venous cannulae connected to 3/8 in...

A double cannula is described suitable for the aspiration of soft lens matter. The cannula is a modification of a double irrigation needle already marketed and will be available in a presterilised disposable pack for use with disposable syringes.

OBJECTIVE To investigate the value of high-flow nasal cannula oxygen therapy after extubation in patients with acute respiratory failure. METHODS A single-center, prospective, randomized, controlled pilot trial was conducted between January 2013 and December 2014. Sixty enrolled patients were randomized immediately after extubation into either a high-flow nasal cannula group (n=30) or an air ...

Aortic root and valve clots are rare but well described in patients on maximal left ventricular assist device (LVAD) support. We performed a theoretical analysis using computational fluid dynamic analyses in two dimensions to try and ascertain if inflow cannula design/orientation/placement affect aortic root flow dynamics. Two-dimensional computational fluid dynamics using easy CFD-G was perfor...

Methods: Fat is harvested using disposable Caraway harvest cannula; processed with a bi-laminar filtration system and injected with disposable 18 gauge cannula. Intravenous clindamycin is given 1 hour before surgery and the intraoral mucosa at the site of injection is re-prepped with betadine. The upper lip is retracted and approximately 1–1.5 cm above and medial to the Stensen’s duct, the inje...

BACKGROUND An unanticipated difficult airway is very uncommon in infants. The recommendations for managing the cannot ventilate-cannot intubate (CVCI) situation in infants and small children are based on difficult airway algorithms for adults. These algorithms usually recommend placement of a transtracheal cannula or performing a surgical tracheotomy as a last resort. In this study, we compared...

Malposition of venous cannula can cause inadequate venous drainage during cardiopulmonary bypass. It would be good clinical practice to use TEE to check the position of inferior venous cannula to avoid this problem at the earliest.
