Objective: Less diameter needles may cause less side effect in lumbar anesthesia. However, some Chinese anesthesiologists consider that bigger needles are suitable for emergency surgery, because it can shorten the puncture period. Present study aimed to compare 25-gauge (G) pencil point needle with 22G cutting needle for emergency caesarean section. Methods: In this prospective study, 200 femal...

popularity over the last two decades [1]. This new application of technology also facilitates spinal anesthesia in patients with challenging anatomy, such as those with scoliosis or obesity, or elderly patients [2,3]. Infiniti Plus (CIVCO Medical Solutions, Kalona, IA, USA) is a needle-guidance system that was recently developed to assist clinicians in performing ultrasound-guided nerve blocks....

OBJECTIVE To compare the visibility and procedural parameters between a standard spinal needle and a new laser-etched needle (LEN) in real-time ultrasonography guided lumbar medial branch access in a phantom of the lumbosacral spine. METHODS We conducted a prospective single-blinded observational study at a rehabilitation medicine center. A new model of LEN was manufactured with a standard 22...

To characterize spinal cord effects of needle placement using lumbar puncture myelography technique, lumbar puncture was performed in 5 dogs and computed tomography images of the spinal column were acquired in the transverse plane at the level of the puncture site after contrast injection and both before and after needle removal. The spinal cords were punctured during needle placement and paren...

BACKGROUND previous evidences suggested that traditional sitting position (flexion of knees approximately 90°, and adduction of hips while feet rest on a stool) and hamstring stretch position (sitting position with maximum extension of knees, adduction of hips, and forward bending) both reversed the lumbar lordosis and the number of spinal needle-bone contacts were identical when placing patien...

Background: The post-dural puncture headache (PDPH) is a common complication in spinal anesthesia. Headache may occure seven days after dural puncture. The headache may be worsened in sitting position and be better in supine position. PDPH is common in younger and tall people. The incidence rate of PDPH related to the size of spinal needle and the number of try and decrease with small, cutting ...

BACKGROUND AND OBJECTIVES To investigate the differences in the number of squamous epithelial cells carried to the spinal canal by three different types of spinal needle tip of the same size. METHODS Patients were allocated into three groups (Group I, Group II, Group III). Spinal anesthesia was administered to Group I (n=50) using a 25G Quincke needle, to Group II (n=50) using a 25G pencil po...

OBJECTIVE The aim of this study was to determine which type of spinal needle is preferred from a cost perspective, taking into account costs of the spinal needle and treatment of postlumbar puncture headache. METHODS A decision-analytic model was created to determine the cost of diagnostic lumbar punctures using atraumatic and cutting needles. We assumed a health care system perspective and b...
