Incidence and fatality of neonatal sepsis in intensive care units have been relatively high despite progress in the management of very ill neonates and combined treatment of sepsis with antibiotics. Between 1985 and 1989 944 children (632 premature babies and 312 term babies) were treated in the intensive care unit of the University Children's Hospital of Kiel. The incidence of sepsis was 5% (congenital sepsis 4%, sepsis acquired after birth 1%). ⋯ Early diagnosis and treatment with piperacillin plus cefotaxime reduced the mortality rate of sepsis to 2%. Sepsis never developed under treatment with piperacillin plus cefotaxime. Early recognition of neonatal sepsis by a good blood culture technique and beginning of treatment on first suspicion of sepsis with cefotaxime and piperacillin can improve the results especially in intensive care patients.

In 47 medical and postoperative ICU patients with 57 episodes of sepsis and septic shock, cardiovascular parameters including systemic vascular resistance (SVR), cardiac index (CI), stroke volume index (SVI), left ventricular stroke work index (LVSWI) as well as six scoring systems (APACHE II, Elebute, Goris, HIS, SAPS and SSS) were studied regarding their usefulness in the assessment of disease progression and evaluation of response to supplemental sepsis therapy (immunoglobulins, plasmapheresis). Among the hemodynamic parameters, only a prompt SVR improvement significantly discriminated between ultimate survivors and nonsurvivors. Thus, an increase in SVR (greater than 160 dyn*cm-5*sec, within days 0 to 4, persisting for greater than 24 hours) can serve as a prognostically validated "response" criterion (responders/non-responders: 26/31; mortality: 27% vs. 77%). Non-invasively, the APACHE II score was best suited (specificity: 88%, sensitivity: 67%) to classify hemodynamically defined responders to supplemental sepsis treatment (score-reduction greater than or equal to 4 on day 4 after onset of therapy).

Randomized Controlled Trial Multicenter Study Clinical Trial
Short course single daily ceftriaxone monotherapy for acute bacterial meningitis in children: results of a Swiss multicenter study. Part I: Clinical results.
In a prospective Swiss multicenter study, 119 children (aged three weeks to 15.5 years) with acute bacterial meningitis were treated with single daily doses of ceftriaxone (100 mg/kg on days one and two and 60 mg/kg thereafter). All patients were randomly assigned to either short course (four, six, seven days) or full course (eight, 12, 14 days) therapy depending on whether they had contracted meningococcal, Haemophilus influenzae type b or pneumococcal meningitis. Bacteriological cure was obtained in 92 children who fully completed the study and in all the 20 culture-positive of the 27 children secondarily excluded from the study for failure to meet all bacteriological and initial safety criteria for continuation in protocol (secondary exclusions). ⋯ At follow-up examination three to six months after hospital discharge only seven infants and seven children (11.8%), mostly those with poor presentation on admission (p = 0.0012), showed residual neurological sequelae. Side effects of antibiotic therapy were minor but more frequent, albeit not statistically significant (p = 0.065), in children receiving the full course therapy. The results of this study suggest that short course treatment of acute bacterial meningitis in children with single daily ceftriaxone monotherapy is as efficacious as full course therapy and at least as well tolerated.

Eighteen studies on Selective Decontamination of the Digestive Tract (SDD) have been published up to now. A statistically significant reduction of infection rate was found in fourteen out of the fifteen controlled studies. Although all the studies were designed to evaluate infection-related morbidity as the end point, ten centres have reported fatality rates. ⋯ The Paris trial suggests a major impact of the SDD maneuver on the ICU ecology. Emergence of resistance to the SDD agents among gram-positive cocci has been described, although the clinical impact of this antibiotic side effect has not been reported so far. There are three indications for SDD, as follows: (i) trauma patients; (ii) liver transplant recipients and (iii) outbreaks of multi-resistant organisms.

Chest physiotherapy is a treatment program that attempts to compensate for impaired mucociliary clearance. By removing mucopurulent secretions, it reduces airway obstruction and its consequences, such as atelectasis and hyperinflation; furthermore, physiotherapy can decrease the rate of proteolytic tissue damage by removing infected secretions. Conventional physiotherapy (clapping, vibration and compression, together with postural drainage and assisted coughing) is the most efficient physiotherapy for sick infants and young children. ⋯ Autogenic drainage, a special breathing technique, aims at avoiding airway compression by reducing positive expiratory transthoracic pressure. PEP-mask-physiotherapy achieves the same goal by expiring against an external airflow obstruction. Last but not least, physical exercise can clear the lungs of some CF patients and thus offers an attractive adjunct to physiotherapy.
