Aktualisierte Kurzfassung der Leitlinien zur Pr?vention, Diagnostik und Therapie der nosokomial erworbenen Pneumonie

Hintergrund:  

Die nosokomiale Pneumonie gehört zu den häufigsten nosokomialen Infektionen und ist die häufigste auf der Intensivstation. Die nosokomiale Pneumonie ist mit einer signifikanten Mortalität und Morbidität assoziiert, und ihr Auftreten verschlechtert die Prognose des Patienten deutlich. Nach der Definition der DRGs auch im deutschen Krankenhaussystem ist die nosokomiale Pneumonie überwiegend Sache des Krankenhauses und kann somit nicht nur das Ergebnis der Patientenbehandlung, sondern auch das finanzielle Ergebnis des Krankenhauses beeinträchtigen.

以脑室出血为首发表现烟雾病患者的护理

对16例以脑室出血为首发表现的烟雾病患者行侧脑室引流术，结果患者手术均获成功，无并发症发生。平均住院13．6d出院。提出术前进行心理护理，做好充分术前准备；术后密切观察病情变化，正确掌握脑室引流袋的高度，观察引流液的量和颜色，保持脑室引流通畅；做好腰穿置管后脑脊液置换的护理，及时观察并发症的发生，予以出院指导等，对巩固手术疗效，促进患者康复至关重要。

BACKGROUND: Consequences of the volume outcome relationship are controversial. Objectification based on data analysis is strongly needed. The aim of this publication was to analyse the effects of volume outcome reallocations based on German inpatient data. METHOD: The analysis based on inpatient data of the Krankenhauszweckverband Koeln, Bonn und Region (Hospital Association of the Cologne and Bonn Region) of 2002 and 2005. Relevant data sets were identified according to the effects of current German regulations on volume outcome on the special fields liver transplant, kidney transplant, complex pancreatic surgery, and complex oesophageal surgery. RESULTS: The effects of current German regulations on volume outcome results differed greatly between the four surgical specialities. There were fewer effects on kidney transplant, but due to an already very high level of centralisation 34% (oesophagus) and 8% (pancreas) of the hospitals stopped related surgery. This affected 8.9% (oesophagus) and 2.2% (pancreas) of related cases. CONCLUSION: Concentration and the formation of specialised medical centres are results of the implementation of volume outcome relationships. The quality of medical treatment does not automatically improve from this development. It is necessary to analyse any correlation between quality and frequency of treatment or other criteria such as know-how, structure and process management, and multidisciplinarity.     

Plasma Norharman (β-Carboline) Levels are Elevated in Chronic Alcoholics

Based on the hypothesis that condensation products of neurotransmitters with aldehydes are involved in the pathogenesis of alcoholism, aromatic beta-carbolines (norharman and harman) were measured in the blood plasma of alcoholics and nonalcoholics. The identity of the extracted compounds was confirmed by various elution conditions of the high performance liquid chromatography (HPLC), newly developed radioreceptor assays, and the mass spectrum of norharman. The levels of norharman and harman in nonalcoholics were unchanged after a load with ethanol (1 g/kg body weight). The norharman levels of the alcoholics were significantly higher than that of the nonalcoholic controls (99.5 +/- 26.6 pg/ml vs. 26.9 +/- 10.7 pg/ml; p less than 0.001) and did not change significantly during a 3-week detoxication period. In the subgroup of alcoholics with delirium or hallucinosis, a slight increase of norharman during detoxication could be detected while in alcoholics with vegetative withdrawal symptoms norharman levels dropped slightly over time (p = 0.07). No difference was found with respect to harman between nonalcoholics and alcoholics. These results suggest disturbed regulatory processes in the formation and/or metabolism of norharman in alcoholics. Further investigations are needed to reveal a possible marker function of norharman in alcoholic patients.     

The use of telescoping guide catheters for coronary sinus cannulation and sub-selecting tributaries in left ventricular lead placement

Introduction Failure to enter the coronary sinus (CS) with a guiding catheter and entering its tributaries remains challenging in left ventricle (LV) pacing lead implants for cardiac resynchronization therapy (CRT). A dual telescoping catheter system (8F outer/6F inner) is designed to provide the ability to adjust the catheter curve size, shape and/or reach to the patients’ anatomy avoiding the need for catheter change. Methods Five different designs for CS cannulation were randomly tested in 64 patients scheduled for CRT device implant. Results In 33 consecutive patients three adaptable telescoping guiding catheter systems were tested per patient, the adaptable catheters had higher overall cannulation success rates (68, 63 and 62%) compared to the fixed shape catheter (46%) and an greater cannulation success rate when the CS location was not known (70, 53 and 72% vs 33% for the fixed shape). In a second group of 31 CRT patients the two telescoping catheters had similar high levels of success (71–80%), with or without using the inner catheter. Conclusions The telescopic system is adaptable to a wide range of anatomical variations in patients and can result in a higher CS cannulation success rate due to its adjustability in the RA in search for the CS ostium. On top of this the inner catheter allows for sub-selecting the CS tributaries.     

Neonatal Exposure to a Combination of N-Methyl-d-aspartate and γ-Aminobutyric Acid Type A Receptor Anesthetic Agents Potentiates Apoptotic Neurodegeneration and Persistent Behavioral Deficits

Background: During the brain growth spurt, the brain develops and modifies rapidly. In rodents this period is neonatal, spanning the first weeks of life, whereas in humans it begins during the third trimester and continues 2 yr. This study examined whether different anesthetic agents, alone and in combination, administered to neonate mice, can trigger apoptosis and whether behavioral deficits occur later in adulthood.

Methods: Ten-day-old mice were injected subcutaneously with ketamine (25 mg/kg), thiopental (5 mg/kg or 25 mg/kg), propofol (10 mg/kg or 60 mg/kg), a combination of ketamine (25 mg/kg) and thiopental (5 mg/kg), a combination of ketamine (25 mg/kg) and propofol (10 mg/kg), or control (saline). Fluoro-Jade staining revealed neurodegeneration 24 h after treatment. The behavioral tests-spontaneous behavior, radial arm maze, and elevated plus maze (before and after anxiolytic)-were conducted on mice aged 55-70 days.

Results: Coadministration of ketamine plus propofol or ketamine plus thiopental or a high dose of propofol alone significantly triggered apoptosis. Mice exposed to a combination of anesthetic agents or ketamine alone displayed disrupted spontaneous activity and learning. The anxiolytic action of diazepam was less effective when given to adult mice that were neonatally exposed to propofol.
