The CT and cerebrospinal fluid (CSF) findings of 100 patients with ruptured intracranial aneurysms were reviewed. Forty six percent of the 68 patients who had a lumbar puncture had blood stained CSF but with no xanthochromia. There was no blood visible on the CT scan in 20 patients: seven of these 20 had blood in their CSF, but no xanthochromia. It is concluded that it is blood stained CSF that...

The aetiology of headache after lumbar puncture is related to the hole left in the dura after the needle has been withdrawn, which allows the cerebrospinal fluid to leak out of the subarachnoid space. The headache can persist for prolonged periods and predispose to subdural haematomas, which are associated with a high mortality. Tourtellotte showed that this headache could be significantly redu...

A remote haptic collaboration system for lumbar puncture learning and training has been proposed. The study built a physical model for the simulation of interaction force between the needle and different tissues and developed a new protocol for real-time force feedback data transmission. Based on the processing delay and preprocessing interpolation, the negative effects on remote haptic percept...

a temperature of 103?F. He was examined and found to have Kernig's sign and all other clinical signs of cerebro-spinal fever. A lumbar puncture was done and about 30 c.cm. of turbid fluid, flowing at slightly increased pressure, were drawn off. This was examined bacteriologically and showed meningococci in abundance. Next day another lumbar puncture was done, 30 c.cm. of fluid drawn off and 20 ...

OBJECTIVES The objective was to determine if use of ultrasound (US) by emergency physicians (EPs) to localize spinal landmarks improves the performance of lumbar puncture (LP). METHODS This was a prospective, randomized, controlled study conducted in a county teaching hospital. Subjects, adults 18 years of age or older who were to receive LPs for routine clinical care in the emergency departm...

Diagnostic lumbar puncture (LP) is essential to the diagnosis of central nervous system infections and subarachnoid haemorrhage. Life or limb-threatening adverse events due to the procedure are rare, but less severe complications may be common. Clinical practice in diagnostic LP is often not evidenced based. The aim of the study was to use best available published evidence to address questions ...

OBJECTIVE To compare the ease of use of atraumatic needles with standard needles for diagnostic lumbar puncture and the incidence of headache after their use. DESIGN Double blind, randomised controlled trial. SETTING Investigation ward of a neurology unit in a university hospital. PARTICIPANTS 116 patients requiring elective diagnostic lumbar puncture. INTERVENTIONS Standardised protoco...

OBJECTIVE To analyse the outpatient management of selected febrile infants younger than 90 days without systematic lumbar puncture and antibiotics. METHODS A prospective registry-based cohort study including all the infants ≤90 days with fever without a source (FWS) who were evaluated in a paediatric emergency department (ED) over a 7-year period (September 2007-August 2014). We analysed the ...

BACKGROUND/AIMS Thrombocytopenia and the increasing use and variety of antithrombotic drugs is a challenge prior to lumbar puncture. This study examined the Danish haematology practice regarding drug pausation, assessment of haemostasis and whether fundoscopy is a routine safety measure. METHODS An online survey with questions pertaining to precautions of haemostasis and application of fundos...
