UNLABELLED The treatment of sacral insufficiency fractures remains an area of active investigation and development, which has typically concentrated on the lateral elements of the sacrum and the sacral ala. Although these fractures frequently involve the first sacral (S1) vertebral body, this structure has eluded a successful technique to accurately access its central portion for percutaneous c...

Albino Wistar rats (either sex, 225 to 250 g) were anesthetized with Sodium pentobarbitone (50 mg/kg, i.p.). Blood pressure was measured with a pressure transducer (T301) on a INCO polygraph through a polypropylene cannula placed in the carotid artery. A polypropylene cannula introduced in the jugulat vein was used for the infusion of drugs. In this study we have tried to ascertain the effect o...

We have designed a cannula system that can be chronically implanted to end above the dura of the cisterna magna of the dog. During experiments in the awake dog, a screw cap with stylet is removed from the cannula and a spinal needle inserted for the withdrawal of samples of cisternal cerebrospinal fluid (CSF) or for making continuous measurements of pressure. The system can be used for repeated...

The first transfusion of blood for hemorrhagic disease of the newborn was performed in New York City by Dr. Alexis Carrel in 1908 [1]. The method was direct transfusion from the left radial artery to the right popliteal vein. The baby recovered. In 1909 Dr. Crile introduced the cuff and cannula method. In 1910 the Elsberg cannula was introduced, and during the same year, Vincent of Boston intro...

Background: A peripheral intravenous cannula is an essential tool for delivering drugs, blood products, and nutritional fluids to patients intravenously. At least 90% of all who enter the medical environment care have some form therapy. Giving medications through can be complicated due its association with serious infections.Aims study: The study aimed evaluate effectiveness intervention progra...

BACKGROUND Lung ventilation through a thin transtracheal cannula may be attempted in patients with laryngeal stenosis or "cannot intubate, cannot ventilate" situations. It may be impossible to achieve sufficient ventilation if the lungs are spontaneously emptying only through the thin transtracheal cannula, which imposes high resistance to airflow, resulting in dangerous hyperinflation. Therefo...

A quantitative primate model of arterial thromboembolism has been characterized with respect to mechanism and usefulness in evaluating modifying variables. The model involved the kinetic measurements of (51)Cr-platelets and (125)I-fibrinogen consumption by femoral arteriovenous cannulae in chaired baboons. Cannula platelet consumption correlated directly with exposed cannular area for irradiate...

BACKGROUND Endoprosthesis are being used in the everyday clinical practice either as a permanent solution or transient. They can be used in both benign and malignant situations. CASE PRESENTATION We report a case in which a temporary Montgomery cannula is used in conjunction with therapeutic bronchoscopy to manage a patient with failed tracheostomy decannulation secondary to a distal complex ...

A 63-year-old man presented to the emergency department after an episode of transient left hemiparesis and hemianaesthesia. His only history of allergy was an episode of mild urticaria after a postsurgical fentanyl infusion a few years previously. An intravenous cannula was inserted in his left cubital fossa. His neurological symptoms had resolved completely by the time he was reviewed by the n...
