BACKGROUND Computed tomography (CT)-guided transthoracic needle biopsy is reliable and has become popular for diagnosing pulmonary lesions. Pneumothorax is the most common complication of transthoracic needle biopsy. The aim of this study was to report our preliminary experience with a three-step needle withdrawal technique for CT-guided lung-biopsy, with emphasis on reduction of the pneumothor...

BACKGROUND The reported incidence of transient neurological symptoms (TNS) after subarachnoid lidocaine administration is as high as 40%. We designed this clinical trial to determine the incidence of TNS with two different pencil-point spinal needles: one-orifice (Atraucan) and two-orifice (Eldor) spinal needles. METHODS Ninety-nine ASA physical status I or II patients undergoing surgical pro...

Bevelled spinal needles sizes 22 and 25 gauge were passed through tough meat to assess the influence of bevel orientation on the path of the needle. The needle bent away from the bevel surface by about 1 mm for each centimetre of needle travel through the tissue. With an introducer, the deviation was reduced by a reduction of the distance of unsupported travel. Pencil-point needles were less de...

purpose: to compare the efficacy and safety of two local anesthetic methods; retrobulbar anesthesia and parabulbar anesthesia using ptfe intravenous cannula without needle in extracapsular cataract surgery. method: a randomized prospective partially blind study was conducted on 66 eyes of 66 patients with senile cataract who were scheduled for ecce and pc iol surgery. after randomization, 35 pa...

Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-...

BACKGROUND AND PURPOSE Vertebroplasty performed in the mid- and upper thoracic spine presents technical challenges that differ from those in the lower thoracic and lumbar region. We herein report results of percutaneous vertebroplasty for treatment of painful, osteoporotic compression fractures in the mid- and upper thoracic spine. METHODS Retrospective chart review identified vertebroplasty ...

BACKGROUND/AIM Postdural puncture backache (PDPB) is the most frequent complaint after spinal anesthesia. In the literature its importance is generally overshadowed by postdural puncture headache. We studied two different kinds of spinal anesthesia needles to compare their technical handling capacities and incidences of PDPB. MATERIALS AND METHODS Data of 256 pregnant female patients undergoi...

INOCULATION OF THYMUS IN SITU. The thymus of C57BL/Ka mice, aged 24 hr or less, was exposed by the technic described by Miller for neonatal thymectomy (10). A very small volume, less than 0.01 m], of RLV was injected into the right thymic lobe, using a 30-gauge needle; it was impossible to avoid some leakage of the inoculated material. The opening in the chest wall was sutured, and the babies w...
