A multi-centre randomised open trial was done to determine whether moderate oral fluid restriction or intravenous fluid at full maintenance volumes would result in a better outcome for children with bacterial meningitis in Papua New Guinea, and what clinical signs could guide fluid management. Children with clinical signs and cerebrospinal fluid suggestive of bacterial meningitis received either breast milk by nasogastric tube at 60% of normal maintenance volumes (n = 172) or intravenous half-normal saline and 5% dextrose at 100% of normal maintenance volumes (n = 174) for the 1st 48 hrs of treatment. An adverse outcome was death or severe neurological sequelae, and a good outcome was defined as intact survival or survival with at worst mild-to-moderate neurological sequelae. The probability of an adverse outcome was 24.7% in the intravenous group and 33.1% in the oral-restricted group, but the difference was not statistically significant (RR 0.75, 0.53-1.04, p = 0.08). Sunken eyes or reduced skin turgor at presentation were risk factors for an adverse outcome (OR 5.70, 95% CI 2.87-11.29) and were most strongly associated with adverse outcome in the fluid-restricted group. Eyelid oedema during treatment was also a risk factor for an adverse outcome (OR 2.54, 95% CI 1.36-4.75) and eyelid oedema was much more common in the intravenous group (26%) than in the restricted group (5%). For many children with bacterial meningitis in less developed countries, moderate fluid restriction is unnecessary and will be harmful; a normal state of hydration should be achieved but over-hydration should be avoided. Giving 100% of normal maintenance fluids, especially with intravenous hypotonic fluid, will lead to oedema in up to one quarter of children with bacterial meningitis. If additional intravenous fluids are required for children with meningitis, an isotonic solution should be used. 相似文献

This study determined independent predictors of the occurrence of permanent neurological sequelae or death after childhood bacterial meningitis. Data were used from a large study on children (aged 1 mo to 15 y) initially presenting with meningeal irritation. A nested case-control study was performed on children with (n = 23) and without (n = 70) permanent neurological sequelae (hearing impairment, locomotor dysfunction, mental retardation or epilepsy) or death after bacterial meningitis. Predictors obtained from clinical evaluation and laboratory tests at presentation and during the clinical course were identified by multivariate logistic regression and receiver operating characteristic (ROC) curve analyses. The study population comprised 23 cases and 70 controls (52% boys, median age 2.8 y). Independent predictors for an adverse outcome after bacterial meningitis were male gender, atypical convulsions in history, low body temperature at admission and the pathogen Streptococcus pneumoniae. The area under the ROC curve of this prediction rule was 0.87 (95% confidence interval: 0.78-0.96), which was not improved by adding other characteristics. A score including these independent predictors could classify patients into categories with increasing risk for an adverse outcome. Conclusion: Clinical characteristics available early in the clinical course, such as gender, atypical convulsions in history, low body temperature at admission and the pathogen, are predictive for the occurrence of permanent neurological sequelae or death after bacterial meningitis in childhood. The pathogen type, in particular, is the main prognostic determinant of childhood bacterial meningitis. 相似文献

Duration of symptoms and outcome in bacterial meningitis: an analysis of causation and the implications of a delay in diagnosis. 总被引:2,自引:0,他引:2
M Radetsky 《The Pediatric infectious disease journal》1992,11(9):694-8; discussion 698-701
The prompt diagnosis and therapy of bacterial meningitis remain enduring clinical challenges, for no physician would knowingly delay appropriate therapy. However, whether a delay in the initiation of antimicrobials in fact causes a worse outcome is a separate and tangential question. In clinical medicine a treatment decision involves a bedside estimate of the risk and potential severity of illness balanced against the benefits and adverse effects of therapy. For severe infections, the inexorable damage of untreated disease is presumed, and antimicrobials properly are given without hesitation. In contrast the methodical weighing of evidence regarding the issue of causation is for the purpose of characterizing biologic phenomena. Although legal and medical implications may be contained in such an analysis, its relevance to any particular clinical case is only retrospective. To judge responsibly the strength of a causative link, all available scientific evidence must be analyzed by established criteria. Such as analysis suggests that any connection between a delay in the treatment of bacterial meningitis and outcome depends on the presenting clinical pattern. If the presentation is that of a nonspecific illness with general symptoms, then a short delay of < 3 to 5 days does not appear to alter the risk of sequelae or death. In the case of fulminant meningitis a delay in initiating therapy seems unconnected to outcome. Finally for patients with a history of clinically overt meningitis, an inappropriate delay in commencing therapy incrementally increases the risk of permanent injury. 相似文献

Clinical indicators for lumbar puncture 总被引:1,自引:0,他引:1
This study was conducted to demonstrate that experienced pediatricians using standard clinical indications for performing a lumbar puncture should have a higher yield of positive spinal taps than previously reported and also can detect bacterial meningitis. These indicators included temperature elevation, inability to be consoled, level of alertness, nuchal rigidity, bulging fontanel, decreased appetite, rash, referral, and febrile seizures. Eighty-two of 381 (22%) lumbar punctures were positive for pleocytosis and/or organisms. Patients were divided into two groups, consisting of those with one indicator (low risk) and those with greater than one indicator (high risk). Thirteen of 14 patients with bacterial meningitis were placed in the high risk group. The single patient in the low risk group had been pretreated with antibiotics. The positive predictive value in bacterial meningitis for a score greater than one was 5%. The average number of clinical indicators in bacterial meningitis was 3.7, versus 2.4 in viral meningitis and 1.6 without meningitis. These findings suggest that, in the absence of prior antibiotic therapy, an experienced pediatrician can clinically detect patients at high risk for bacterial meningitis. Nonbacterial meningitis cannot be as readily detected clinically. 相似文献

Risk factors for development of bacterial meningitis among children with occult bacteremia 总被引:1,自引:0,他引:1
To identify risk factors for the development of bacterial meningitis, we compared clinical characteristics in children with occult bacteremia who did and those who did not subsequently develop bacterial meningitis. The estimates of risk were adjusted for the possible confounding effects of other characteristics by using logistic regression. Of 310 children (median age 15 months) who had occult bacteremia with Streptococcus pneumoniae, Haemophilus influenzae type b, or Neisseria meningitidis at either Yale-New Haven Hospital or Children's Hospital of Pittsburgh, bacterial meningitis subsequently developed in 22 (7%). Compared with the risk associated with occult bacteremia with S. pneumoniae, the adjusted relative risk for bacterial meningitis was 85.6 (P less than 0.0001) and 12.0 (P = 0.0001) for N. meningitidis and H. influenzae type b, respectively. By contrast, the adjusted relative risk associated with a lumbar puncture at the initial visit was only 1.2 (P = 0.78). The development of bacterial meningitis in children with occult bacteremia is strongly associated with the species of bacteria that causes the infection, but not with a lumbar puncture or with other clinical characteristics identifiable at the initial visit. 相似文献

Randomized trial of four vs. seven days of ceftriaxone treatment for bacterial meningitis in children with rapid initial recovery 总被引:1,自引:0,他引:1
Roine I Ledermann W Foncea LM Banfi A Cohen J Peltola H 《The Pediatric infectious disease journal》2000,19(3):219-222
BACKGROUND: Seven days or more of antimicrobial treatment is the standard for bacterial meningitis, although third generation cephalosporins are usually able to sterilize cerebrospinal fluid within 24 h. The limited experience from shorter regimens in children is encouraging, and we hypothesized that in rapidly recovering patients older than 3 months of age it would pose no risk for adverse outcome. METHODS: Strict clinical and laboratory criteria were used to define rapid initial recovery, in which case ceftriaxone therapy was either stopped after 4 days (4 injections) in children born on even dates (N = 53) or continued for 7 days in patients born on odd dates (N = 47). Outcomes were compared on Day 7 of hospitalization and at 1 to 3 months after discharge. RESULTS: On Day 7 no differences (P > 0.05 for each criteria) were observed between the 4-day and the 7-day groups regarding fever, clinical signs or serum C-reactive protein concentration. At the follow-up visit 1 to 3 months after discharge the 4-day group had fewer sequelae than the 7-day group (0% vs. 5% neurologic sequelae, P = 0.39 and 3% vs. 9% hearing loss, P = 0.49, respectively). One child in the 4-day group who had fully recovered was subsequently readmitted 53 days after the first hospitalization with recurrent Haemophilus influenzae meningitis. CONCLUSIONS: Four days of ceftriaxone therapy proved to be a safe alternative in patients with rapid initial recovery from bacterial meningitis. A 4-day course of treatment is particularly beneficial for countries with limited resources. 相似文献
