Two methods for transcervical cannulation of the goat were evaluated during a contraception study in 15 adult female Nigerian dwarf and African pygmy goats. Twenty-four transcervical cannulation procedures were conducted in which seven females underwent the procedure 2-3 times. Initially, a rigid 4-mm stainless steel cannula and external light source were used in 19 procedures to introduce the ...

The bioavailability of recombinant human growth hormone (somatropin, CAS 12629-01-5) was compared between a transcutaneous jet injection device and subcutaneous cannula injection. Thirteen healthy male subjects received 8.64 IU somatropin once with jet and once with cannula injection in a randomized cross-over study. Baseline-corrected somatropin serum concentrations were evaluated with non-com...

The use of a dual lumen cannula (DLC) for venovenous extracorporeal membrane oxygenation (ECMO) has several advantages and reports of complications are rare. We present a case of thrombosis around and inside the Avalon Elite™ bicaval DLC (Avalon Laboratories, Rancho Dominguez, CA, US), for which simple removal by retraction was impossible. A 30-year-old man had experienced an unstable C6/7 frac...

BACKGROUND In patients with left ventricular non-compaction (LVNC), implantation of a left ventricular assist device (LVAD) may be performed as a bridge to transplantation. In this respect, the particular characteristics of the left ventricular myocardium may represent a challenge. CASE PRESENTATION We report a patient with LVNC who required urgent heart transplantation for inflow cannula obs...

The combination of helium with oxygen is less dense than air and as such has been beneficial to patients with airflow obstruction within the large airways. The purpose of this study was to evaluate the effectiveness of delivering He-O2 by open-circuit systems by measuring DD50 in five adult volunteers. The mean (+/- SD) DD50 with a nonrebreathing mask was 1.32 +/- 0.89, with a simple mask was 1...

BACKGROUND The implantation of ventricular assist devices is a well-established procedure for the treatment of imminent heart failure. The exact positioning of the left ventricular apical inflow cannula is crucial, because inflow restrictions might occur when the cannula is placed too close to the interventricular septum or a papillary muscle. We report a novel technique using the Tentacles 3-p...

The Effect of Feeding with Different Levels Cannula as a Fat Supplement in the Initial Diet on Performance and Ruminal Blood Metabolites Early Weaning Goats Mahabadi

Tension pneumothorax can occur as a potentially life threatening complication of chest trauma. is commonly treated with needle decompression, both the 2nd intercostal space in midclavicular line and 4th/5th anterior axillary. A 45 years old man came to our emergency department after blunt injury presenting tension unstable hemodynamic decompression using 14 gauge (4.5 cm) cannula at mid clavicu...

BACKGROUND Oxygen therapy is usually combined with a humidification device, to prevent mucosal dryness. Depending on the cannula design, oxygen can be administered pre- or intra-nasally (administration of oxygen in front of the nasal ostia vs cannula system inside the nasal vestibulum). The impact of cannula design on intra-nasal humidity, however, has not been investigated to date. OBJECTIVE...

The performance of open-heart surgery necessitates the cannulation of a major artery to replace, into the patient, blood being returned from the pumpoxygenator. Originally the subclavian artery was used as it was thought that this would ensure good brain and coronary perfusion. With the change to a median sternotomy (Julian, Lopez-Belio, Dye, Javid, and Grove, 1957; Lillehei and Cardozo, 1959) ...
