INTRODUCTION Cannulation of arteriovenous fistula (AVF) may be performed by the following techniques: area puncture, rope ladder, or buttonhole. The ideal technique has not yet been established. OBJECTIVE To assess the complications and difficulties of introducing the buttonhole (BH) technique for cannulation of AVF created with a native vein in a dialysis unit. METHODS Sixteen patients (me...

BACKGROUND Peripheral venous cannulation is an everyday practice in hospitals, which many adults find painful. However, anaesthesia for cannulation is usually only offered to children. Inadequate pain relief is not only unpleasant for patients but may cause anxiety about further treatment and deter patients from seeking medical care in the future. The aim of this study is to discover the most e...

Introduction: Of the numerous approaches for internal jugular venous cannulation, anterior approach is being widely practiced. But the major complications of this approach are carotid artery puncture and hematoma. With posterior approach, there is lesser incidence of arterial puncture and hematoma. Materials and Methods: This study was conducted over a period of 9 months. The aim of this study ...

Purpose A prototype steerable catheter was designed for endovascular procedures. This technical pilot study reports the initial experience using the catheter for cannulation of visceral arteries. Technique The 7F catheter was manually steerable with operator control handle for bending and rotation of the tip. The maximum bending angle was approximately 90° and full 360° rotation of the tip wa...

Though most cardiac operations are performed through median sternotomy because of its versatility and familiarity to surgeons, the fact is sternotomy is not without complications, and the problems of post sternotomy pain, dehiscence, mediastinitis, osteomyelitis and unstable sternum increases morbidity and mortality in these patients. Median sternotomy may also leave a bad scar which patients d...

Aim. Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used for the diagnosis and treatment of hepatic, biliary tract, and pancreatic disorders. However, failure during cannulation necessitates other interventions. The aim of this study was to establish parameters that can be used to predict failure during ERCP. Methods. A total of 5884 ERCP procedures performed on 5079 patien...

1254 May 2014 H micro-ultrasound is a new, preclinical technology that utilizes higher frequencies compared to conventional ultrasound. During a feasibility trial using high-frequency micro-ultrasound for vascular access in children, radial artery spasm in an 8-month-old male child was uniquely documented with a 50-MHz probe. The intraluminal diameter before attempted cannulation was 2.1 mm (fi...

STUDY OBJECTIVE To determine whether the use of subcutaneous local anaesthetic (lignocaine) is associated with a reduction in cannulation pain in the emergency department setting. METHODS Patients over 18 with a Glasgow Coma Score (GCS) of 15 and conversational English were allocated into one of three groups: Group 1 were cannulated after routine skin preparation; Group 2 received 1% lignocai...

Neuropsychological impairment is a very common complication of cardiopulmonary bypass (CPB). The principal cause of postoperative cognitive impairment is thought to be cerebral microemboli during CPB. We recently investigated the effects of perfusionist interventions and aortic cannulation techniques on cerebral emboli production during coronary bypass (CABG) surgery. Patients undergoing isolat...
