BACKGROUND AND OBJECTIVES Lidocaine concentration potentially able to determine nervous tissue injury is still not well established. This study aimed at investigating the effect of increasing spinal lidocaine concentrations in single injection through Quincke needle. METHODS After the Animal Experiment Ethical Committee approval, 40 adult animals were anesthetized with fentanyl and etomidate ...

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...

We compared eight spinal needle biopsy procedures performed with an investigational disposable real-time stereotactic device and eight spinal needle freehand biopsies in which a standard technique was used, to determine whether the investigational device added value to the procedure. The device uses a simple stereotactic diaphragm pattern to define two vector points. The procedures in which the...

Background: Spinal anesthesia is a type of neuraxial anesthesia that brings ample benefits. However, due to the fear of this type of anesthesia, many pregnant people refuse to experience it. In this study, we aimed to investigate the levels and causes of fear of spinal anesthesia in candidates for cesarean section. Methods: The current study is a cross-sctional study performed on 67 patients u...

BACKGROUND Current methods of locating the epidural space rely on surface anatomical landmarks and loss-of-resistance (LOR). We are not aware of any data describing real-time ultrasound (US)-guided epidural access in adults. METHODS We evaluated the feasibility of performing real-time US-guided paramedian epidural access with the epidural needle inserted in the plane of the US beam in 15 adul...

BACKGROUND AND OBJECTIVES This study was conducted to investigate the effects of reinsertion of the stylet after a spinal anesthesia procedure on the Post Dural Puncture Headache (PDPH). METHODS We have enrolled into this study 630 patients who were undergoing elective operations with spinal anesthesia and randomized them to Group A (stylet replacement before needle removal) and Group B (need...

BACKGROUND Current recommendations for spinal tuberculosis (TB) not requiring open surgery include core needle biopsy to confirm TB and determine drug sensitivity. International figures show the positive culture yield from core needle biopsies is 50 -- 83%.Objectives. To (i) assess the yield of percutaneous needle biopsies; (ii) identify factors that may lead to a negative result; and (iii) det...

Cost containment is a critical factor in today's healthcare industry, so finding ways to decrease length of stay is essential in anesthesia practice. We rely on rapid induction, recovery, and discharge to control cost in outpatient surgery. Subarachnoid block (SAB) is an acceptable anesthetic choice for many outpatient procedures. It is often underused because it may result in delayed discharge...

Aim: To asses the incidence of PDPH in different gauges of spinal needle in relation to age. Methods: This Comparative Study was carried out at AFIU (RWP), Railway General Hospital Rawalpindi and Children Complex Multan from August 2007 to August 2008. A total of 1500 patients were studied in 9 different groups (A1, B1, C1, A2, B2, C2, A3, B3, C3) with group A,B and C for 23G, 25G and 27G respe...
