results the rate of first-time successful spinal needle insertion was not significantly different between the clsp and tsp groups (62.9% versus 55.7%, p > 0.05). ease of landmark palpation in the clsp group was not significantly different from that in the tsp group (86.7% versus 76.4%, p > 0.05). the number of needle-bone contacts in both groups were not significantly different (p > 0.05). the ...

conclusions there is clinical utility in knowing the relative deflection of various needle tips. when a procedure requires a needle to be steered around obstacles, or along non-collinear targets, the predictable and large amount of deflection obtained through use of a beveled spinal needle may prove beneficial. materials and methods six needles commonly used in spinal procedures (quincke, short...

conclusions in squatting position the number of spinal needle-bone contacts was lower compared to the traditional sitting position, nonetheless ease of needle insertion or space identification was the same in the both groups. results the total number of spinal needle bone contact was statistically lower in the squatting position compared to traditional sitting position group (222 versus 230 res...

background: although a variety of methods have been suggested to reduce stress, anxiety and pain intensity due to spinal needle skin puncture, their adverse effects restrict theirs widespread administration. in this study we evaluated the effects of oral tizanidine on the reduction of pain caused by spinal needle puncture and hemodynamic responses. methods : in this double blind randomized clin...

OBJECTIVE The study was designed to compare the insertion characteristics and incidence of PDPH between 25 gauge Quincke needle and 26 gauge Eldor needle for spinal anaesthesia in elective c/s. METHOD 60 pregnant women (aged 19-35 yrs and weighing 58 -67 kg) undergoing elective caesarean section were randomized into group A (Quincke spinal needle group) or group B (Eldor spinal needle group)....

Post spinal puncture headache (PSPH) is a well known complication of spinal anesthesia. It occurs after spinal anesthesia induction due to dural and arachnoid puncture and has a significant effect on the patient’s postoperative well being. This manuscript is based on an observational study that runs on Babol University of Medical Sciences and review of literatures about current concepts about t...

objectives this study aimed to examine the relationship between patients’ anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. patients and methods 385 patients with asa class i – ii, aged 18 - 65 years and undergoing elective surgery of the lower abdomen and extremities under spinal anesthesia, were selected for this cross-sectional study. the patient...

BACKGROUND Postdural puncture headache (PDPH), mainly resulting from the loss of cerebral spinal fluid (CSF), is a well-known iatrogenic complication of spinal anesthesia and diagnostic lumbar puncture. Spinal needles have been modified to minimize complications. Modifiable risk factors of PDPH mainly included needle size and needle shape. However, whether the incidence of PDPH is significantly...
