Variations in the flow of cerebrospinal fluid through spinal needles.

Cerebrospinal Fluid and Spinal Anesthesia Parameters in Healthy Versus Opium-Addict Patients during Lower Limb Surgery

مدل‌سازی عددی هیپوترمی مغزی با استفاده از سرد کردن مایع مغزی-نخاعی

Background: Brain hypothermia by reducing the temperature of the cerebrospinal fluid is done by a cooling pad in the thoracic region and protect brain from the ischemic injuries. Along with the spinal cord, the brain is an essential partner in the central nervous system, and similarly, it is surrounded and protected from the bony skull and from shock by cerebrospinal fluid. The brain analyzes i...

Diagnostic and therapeutic lumbar puncture performed safely and efficiently with a thin blunt needle.

INTRODUCTION The risk of postdural puncture headache following lumbar puncture can be reduced by choosing a blunt spinal needle or by using a smaller needle diameter. Reports indicate that lumbar puncture practiced outside of the anaesthetic discipline does not adhere to the current level of evidence. To examine the practice among haematologists in Denmark, we performed a national survey. In ad...

Quantitative assessment of physiological cerebrospinal fluid flow in the cervical spinal canal with 3.0T phase-contrast cine MRI☆

A total of 50 healthy volunteers aged between 18 and 54 years underwent phase-contrast cine MRI to assess cerebrospinal fluid flow characteristics in different regions of the vertebral canal. The results revealed that the cerebrospinal fluid peak flow velocity and peak flow rate in the systolic phase were significantly greater than those in the diastolic phase at the same level in the subarachn...

Investigation of Cerebrospinal Fluid Flow Characteristics Through Adult and Pediatric Shunt Tubing

Shunt malfunction in adult and pediatric populations continues to be a perplexing problem. We examined artificial cerebrospinal fluid flow differential between adult and pediatric shunt systems. Flow through adult and pediatric-sized catheters was compared with artificial CSF using shunt systems containing new catheters, explanted catheters, 2-piece catheters, 3-piece catheters and with varying...
