peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. the key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. this study was conducted in order to evaluate the catheter survival and its related factors in imam khomeini hospital. a total of 80 catheters were inserted into 69...

A 23-year-old primigravid patient who received epidural analgesia for pain of labour presented with persistent, apparently irremediable, unilateral analgesia. Computerized axial tomo-epidurography demonstrated absence of circumferential spread due to lateral placement of the catheter. Transforaminal escape of contrast medium into the paravertebral area had occurred and anterior and posterior mi...

Intercostal nerve blockade is a useful adjuvant technique for the relief of pain after thoracic operations (Moore, 1975). However, a series of blocks may be necessary to produce adequate analgesia of the skin. Prolongation of the duration of analgesia can be achieved with catheter techniques, and a system in which a single catheter is utilized would be a useful addition to the armamentarium of ...

Paravertebral blocks have been demonstrated to represent an interesting alternative to epidural, especially for the management of perioperative and trauma pain. Initially performed mostly as single-shot blocks for breast surgery, thoracotomy, and hernia repairs in adults and children, presently these blocks are also used for placement of a paravertebral catheter, either unilateral or bilateral....

PURPOSE To assess the effectiveness and clinical outcomes of catheter-directed thrombolysis in patients with atresia of the inferior vena cava (IVC) and acute iliofemoral deep vein thrombosis (DVT). MATERIALS AND METHODS From 2001 to 2009, 11 patients (median age, 32 y) with atresia of the IVC and acute iliofemoral DVT in 13 limbs were admitted for catheter-directed thrombolysis. Through a mu...

Objectives. The aim of this study was to compare postoperative pain and respiratory functions of lobectomy patients who were given bupivacaine or levobupivacaine with fentanyl through a paravertebral catheter. Methods. ASA I-II patients (n=40, 18-65 years old) randomized into two groups. While Group B was administered 0.25% bupivacaine with fentanyl, Group L was administered 0.25% levobupivacai...

Background: General anesthesia with endotracheal intubation has remained the most common technique used for open renal surgeries because of the abnormal body position and its ability to control the diaphragmatic movement during the surgery. Combined spinal and thoracic paravertebral block (TPVB) can be used as alternative technique for open renal surgery, where spinal anesthesia provides fast a...

We described in this report a case of post-herpetic neuralgia refractory to medical therapy that was successfully treated with repetitive injections of local aesthetic mixture (bupivacaine 0.5% 19 ml and clonidine 150 microg ml(-1) 1 ml) every 48 h for 3 weeks using a paravertebral catheter inserted at T2-T3 level.
