Post-dural puncture headache in young patients. A comparative study between the use of 0.52 mm (25-gauge) and 0.33 mm (29-gauge) spinal needles.

In a prospective study of 80 patients under 40 years of age, given spinal anaesthesia through either a 0.52 mm (25-gauge) needle or a 0.33 mm (29-gauge) needle, the incidence of post-dural puncture headache and backache was compared. There were no headaches in the 0.33 mm needle group, while in the 0.52 mm needle group an incidence of 25% was found. The incidence of backache was the same in both groups. The technique of performing spinal anaesthesia was evaluated and concluded to be slightly more difficult with a 0.33 mm needle, as estimated by the number of redirections of the needle needed to obtain cerebrospinal fluid. There were no differences between the two needles with respect to obtaining adequate spinal anaesthesia and spread of blockade.

Post-dural puncture headache in young orthopaedic in-patients: comparison of a 0.33 mm (29-gauge) Quincke-type with a 0.7 mm (22-gauge) Whitacre spinal needle in 200 patients.

The incidence of postdural puncture headache (PDPH) following spinal anaesthesia with a 0.33 mm (29-gauge) and two types of 0.7 mm (22-gauge) Whitacre needles was investigated in 400 patients less than 40 years old. The incidence of PDPH was 2% in the 0.33 mm group, and 3.5% in the 0.7 mm group. Headache of other origin was seen in 12 patients (6%) in the 0.33 mm and in five patients (2.5%) in the 0.7 mm group. These differences were not significant. The failure rate was significantly higher in the 0.33 mm group (8.5% vs 2%) than in the 0.7 mm group (P less than 0.05). It is concluded that the 0.33 mm needle is associated with a low incidence of PDPH in young patients, but has a significantly higher failure rate than the Whitacre 0.7 mm needle, which is also a suitable choice in this age-group because of its ease of handling and the low incidence of PDPH.

Spinal anaesthesia with 29 gauge Quincke point needles and post dural puncture headache in 2,378 patients.

Two thousand three hundred and seventy-eight spinal anaesthetics using a 29 G Quincke point needle were administered in a District Hospital between May 1983 and December 1991. The overall post dural puncture headache rate (PDPH) was 1.2% with a maximum of 2.5% in patients between age 30 and 39. PDPH was related to the experience of using 29 G needles (0.5% in consultants versus 2.0% in trainees, P < 0.05).

Mechanisms behind postspinal headache and brain stem compression following lumbar dural puncture--a physiological approach.

BACKGROUND: The cause of postspinal headache and its specific characteristics are unknown, and whether lumbar dural puncture (LP) triggers brain-stem compression in patients with brain oedema is still controversial. METHODS: Hydrostatic effects of distal opening of the dural sac towards the atmosphere are described and applied to the normal brain and the brain with disrupted BBB. Analogue analyses from previous results using an isolated skeletal muscle enclosed in a rigid shell were applied to the brain in an attempt to simulate and verify the haemodynamic effects of distal opening of the spinal canal. RESULTS: The theoretical considerations and the experimental results are compatible with the hypothesis that hydrostatic effects of distal opening of the fluid-filled spinal canal may obliterate the normal subdural venous collapse after a change from the horizontal to vertical position, which may be compatible with postural postspinal headache as occurring close to pain-sensitive meningeal regions. The hydrostatic forces may also initiate transcapillary filtration and aggravate oedema when permeability is increased, which may cause a narrower situation in the brain stem region, perhaps aggravated by venous stasis and a Cushing reflex-induced increase in blood pressure. An magnetic resonance imaging (MRI) picture illustrates how this scenario may separate the subdural space into an upper high- and a lower low-pressure cavity, pressing the brain downwards with sagging of the brain. A life-threatening positive feedback situation for brain-stem compression may develop. CONCLUSION: The present study strongly suggests that postspinal headache and brain-stem compression and other LP-related effects are predictable following LP, without involving CSF leakage, and can be explained by hydrostatic effects triggered by distal opening of the normally closed dural space to the atmosphere.

Accelerated thrombolysis facilitated by direct puncture of occluded prosthetic femoral grafts.

Inability to access occluded grafts is a major limitation to successful thrombolysis and may even preclude it. This paper addresses the problem and offers a new technique of direct puncture of prosthetic grafts through which thrombolysis and angioplasty can be performed. These techniques resulted in accelerated thrombolysis in all 15 patients studied with no failures due to inability to attain graft access.

A simplified puncture technique to reduce contamination with bodily fluids.

A simplified method of percutaneous wire placement is described, designed to decrease the amount of aerosol or spurting bodily fluids associated with wire placement. The technique involves minor modification of standard puncture techniques without the use of additional equipment. The technique has been successfully used in 22 patients and there have been no complications associated specifically with this technique.

Lumbar puncture in suspected neonatal sepsis.

OBJECTIVE: The importance of lumbar puncture (LP) as part of the evaluation of suspected neonatal sepsis is assessed, as it may be the only positive diagnostic test in about 10% of septic babies with meningitis but negative blood cultures. However, LP may compromise respiratory function, and the interpretation of cerebrospinal fluid (CSF) may not be straightforward. CONCLUSION: The clinical setting and the probability of meningitis are important determinants of the likely value of LP. For asymptomatic neonates with obstetric risk factors for sepsis, and for babies with early-onset respiratory distress alone, LP may be delayed and only performed later if blood cultures are positive. This is because hundreds of LP will be needed to diagnose a single case. However, infants with suspected late-onset sepsis should have an immediate LP because finding Gram-negative bacilli or fungi in the CSF will affect treatment choices.

Post dural puncture headache in a pediatric patient with idiopathic intracranial hypertension.

We describe the occurrence of postdural puncture headache (PPDH) in an adolescent with idiopathic intracranial hypertension (IIH) and its successful management with an epidural blood patch. PPDH is a very rare occurrence in patients with intracranial hypertension and is described as a paradoxical situation in the literature. There are only two previous case reports (in adults) of the possible association. A 15-year-old obese patient with a diagnosis of IIH had an uneventful diagnostic spinal tap using a 22G Quincke needle in the pediatric emergency department but returned 24 h later with PPDH. After a failed trial of conservative management, she had an uneventful but curative epidural blood patch with 15 ml of autologous venous blood and was able to return to school the day after the blood patch. Follow-up review by her neuro-ophthalmologist shows resolution of her headaches, considerable improvement in her visual field defect and resolution of papilledema. This is the first report of PPDH and its successful management with an epidural blood patch in a pediatric patient with IIH.

When should an epidural blood patch be performed in postlumbar puncture headache? A theoretical approach based on a cohort of 79 patients.

The aim of the present study was to decide on which day in the course of postlumbar puncture headache (PPH) an epidural blood patch (EBP) should be performed to minimize suffering. A cohort of 79 patients (64 female, 15 male) was followed prospectively for 14 days and the consequences of performing an EBP on different days were studied. If no EBP was performed, the patients would accumulate 141 days with PPH5 (bedridden most of the day), 216 days with PPH4-5 (bedridden more than half the day), and 293 days with PPH3-5 (bedridden half the day or more). If these patients were patched on day 2, 3 or 4 after an initial observation of the PPH grade on day 1, the expected suffering was substantially reduced, and the more the earlier in the course the EBP was performed. If the strategy was to treat only patients with PPH5 with an expected 90% success rate, the reduction compared with no treatment was 50% if treated on day 2, 37% if treated on day 3, and 29% if treated on day 4. The corresponding figures for treating patients with PPH4-5 was a 51, 44 and 29% reduction, and for PPH3-5 the reduction was 62, 49 and 35%, respectively. Irrespective of strategy, the expected reduction of suffering in the cohort was greatest when the EBP was performed early in the course of PPH. It is suggested that the decision to perform an EBP should be made at an early stage and offered to patients who have to lie in bed for more than half a day despite conservative treatment.

Epidural blood patch in the treatment of post dural puncture headache: a double blind study.

A randomised double blind controlled trial of 'epidural blood-patch' as treatment for post-dural puncture headache is presented. The method was successful in 11 out of 12 cases on its first application, the twelfth patient being relieved by a second procedure. None of six patients reported benefit from a 'sham' procedure. The rationale for the use of the technique is discussed.

Idiopathic intracranial hypertension and postlumbar puncture headache.

Idiopathic intracranial hypertension and low cerebrospinal pressure are 2 conditions that are thought to be on opposite ends of the cerebrospinal pressure spectrum. Headache is the prominent component of both conditions. We describe a patient whose evaluation for idiopathic intracranial hypertension resulted in a postlumbar puncture headache. Although not entirely intuitive, we suggest that the 2 conditions can be present in the same patient.

The role of lumbar puncture in the evaluation of dementia: the Durham Veterans Administration/Duke University Study.

The use of lumbar puncture (LP) and cerebrospinal fluid (CSF) analysis in the routine, initial evaluation of patients with dementia continues to be questioned. This is especially true in the investigation of infectious causes of dementia. To explore this question further, the authors performed a retrospective analysis of 672 hospitalized patients specifically evaluated for dementia. LP and CSF analysis were performed on 402 patients (60 per cent); routine bacteriologic, acid-fast, and fungal cultures were also obtained for 333 of these patients. Most patients were white (64 per cent) and male (63 per cent), their mean age being 66 +/- 11 years. Four patients were diagnosed as having meningitis--two with Cryptococcus neoformans, one with apparent Mycobacterium tuberculosis, and one with coagulase-positive Staphylococcus aureus. These patients were characterized by a subacute change in mental status, fever or meningismus, and CSF pleocytosis with abnormal CSF chemistries. None of the patients were found to have newly diagnosed neurosyphilis. The authors conclude that LP and CSF analysis should not be part of the routine evaluation of patients with dementia and should be performed only in the presence of such indications as a subacute duration of dementia, fever, and signs of meningeal irritation.

Subarachnoid hemorrhage diagnosis: lumbar puncture is still needed when the computed tomography scan is normal.

OBJECTIVES: To determine the sensitivity of third-generation CT scanners for diagnosed nontraumatic subarachnoid hemorrhage (SAH) and to assess the impact of symptom duration on sensitivity. METHODS: A retrospective chart review was performed in a university-affiliated tertiary care hospital with an annual ED volume of > 100,000 patients. The target population was all patients who presented to the ED from January 1991 to September 1994 with symptoms suggestive of SAH and who had a final diagnosis of nontraumatic SAH based on either a positive CT scan or positive spinal fluid analysis. Patients referred from outside facilities were included if they had a CT done at the study site. All CT scans were done using third-generation scanners. Official CT scan reports were used to categorize scans as positive or negative. RESULTS: There were 140 patients identified with SAH, with a mean age of 56 years (range 10-88). The sensitivity of CT in the diagnosis of nontraumatic SAH when performed at or before 12 hours of symptom duration was 100% (80/80), and 81.7% (49/60) after 12 hours of symptom duration (95% CI 95-100% and 69.5-90.4%, respectively; p < 0.0001). Eleven of the 140 patients had a negative CT and positive spinal fluid analysis, yielding an overall sensitivity of 92.1% (129/140). CONCLUSION: The sensitivity of third-generation CT scans for SAH decreases with time from the onset of symptoms. In this sample population, CT was able to detect all patients scanned < or = 12 hours after symptom onset. Although the study demonstrated good sensitivity of CT scan reports for SAH when the scan was performed after < or = 12 hours of symptom onset, additional real-time experience is needed to better define the potential risk of a missed SAH should this population not receive the customary lumbar puncture examination in the setting of a negative CT scan.

Lumbar puncture first: an alternative model for the investigation of lone acute sudden headache.

Subarachnoid hemorrhage (SAH) is a diagnosis often considered in patients presenting to the ED with acute sudden headaches, but with normal physical examinations. Standard of care today is for these patients to be investigated by noncontrast CT scan followed by lumbar puncture (LP) for negative CTs. However, given that most investigated patients have benign headaches, most of the CT and LP results are normal. The authors studied, by means of a theoretical analysis, the impact of an alternative diagnostic model, in which LP would be the first (and, in most cases, only) diagnostic test for patients suspected of SAH who met lone acute sudden headache (LASH) criteria. Given reasonable assumptions, for every 100 patients investigated, the "LP-first" model would result in 79 to 83 fewer CT scans and only seven to 11 additional LPs, as compared with traditional strategies. Among ED headache patients meeting LASH criteria, the authors believe use of this model could result in more efficient use of resources, minimal additional morbidity, and equal diagnostic accuracy for SAH.
