Publikationsleistungen der Universitätskliniken für Anästhesiologie

Aim

This study assessed the publication performance of university departments of anesthesiology in Austria, Germany and Switzerland. The number of publications, original articles, impact factors and citations were evaluated.

Material and methods

A search was performed in PubMed to identify publications related to anesthesiology from 2001 to 2010. All articles from anesthesiology journals listed in the fields of anesthesia/pain therapy, critical care and emergency medicine by the “journal citation report 2013” in Thomson Reuters ISI web of knowledge were included. Articles from non-anaesthesiology journals, where the stem of the word anesthesia (anes*, anaes*, anäst*, anast*) appears in the affiliation field of PubMed, were included as well. The time periods 2001–2005 and 2006–2010 were compared. Articles were allocated to university departments in Austria, Germany and Switzerland via the affiliation field.

Results

A total of 45 university departments in Austria, Germany and Switzerland and 125,979 publications from 2,863 journals (65 anesthesiology journals, 2,798 non-anesthesiology journals) were analyzed. Of the publications 23?% could not be allocated to a given university department of anesthesiology. In the observation period the university department of anesthesiology in Berlin achieved most publications (n?=?479) and impact points (1,384), whereas Vienna accumulated most original articles (n?=?156). Austria had the most publications per million inhabitants in 2006-2010 (n=50) followed by Switzerland (n=49) and Germany (n=35). The number of publications during the observation period decreased in Germany (0.5?%), Austria (7?%) and Switzerland (8?%). Tables 2 and 4–8 of this article are available at Springer Link under Supplemental.

Conclusions

The research performance varied among the university departments of anesthesiology in Germany, Austria and Switzerland whereby larger university departments, such as Berlin or Vienna published most. Publication output in Germany, Austria and Switzerland has decreased. Data processing in PubMed should be improved.     

Akzidentelle Hypothermie

Uncertainty exists on how to treat patients suffering from accidental hypothermia and on the optimal transport decisions. The aim of this review is to provide an updated evidence-based reference for the pre-hospital and in-hospital management of patients with accidental hypothermia and for the transport decisions required to facilitate treatment. Advances in the efficiency and availability of rewarming techniques have improved the prognosis for patients presenting with hypothermia. For hypothermic patients with a core body temperature ≥?28?°C without cardiac instability there is increasing evidence to support the use of active external and minimally invasive rewarming techniques (e.g. chemical, electrical or forced air heating packs, blankets and warm parenteral fluids). Hypothermic patients with cardiac instability (i.e. systolic blood pressure <?90 mmHg, ventricular arrhythmia and core body temperature <?28?°C) should be rewarmed with active external and minimally invasive rewarming techniques in a hospital which also has circulation substituting venous-arterial extracorporeal membrane oxygenation (VA-ECMO) and cardiopulmonary bypass (CBP) facilities. In cardiac arrest patients VA-ECMO may be a better treatment option than CBP and survival rates of 100?% can be achieved compared to ~?10?% with traditional methods (e.g. body cavity lavage). Early transport to a hospital appropriately equipped for rewarming has the potential to decrease complication rates and improve survival.

A suction laryngoscope facilitates intubation for physicians with occasional emergency medical service experience—A manikin study with severe simulated airway haemorrhage

Introduction

We developed a suction laryngoscope, which enables simultaneous suction and laryngoscopy in cases of airway haemorrhage and evaluated its potential benefits in physicians with varying emergency medical service experience.

Methods

Eighteen physicians with regular and 24 physicians with occasional emergency medical service experience intubated the trachea of a manikin with severe simulated airway haemorrhage using the suction laryngoscope and the Macintosh laryngoscope in random order.

Results

In physicians with regular emergency medical service experience, there was neither a difference in time needed for intubation [median (IQR, CI 95%)]: 34 (18, 30–46) vs. 34 (22, 30–52) s; P = 0.52, nor in the number of oesophageal intubations [0/18 (0%) vs. 3/18 (16.7%); P = NS] when using the suction vs. the Macintosh laryngoscope. In physicians with occasional emergency medical service experience, there was no difference in time needed for intubation [median (IQR, CI 95%)]: 42 (25, 41–57) vs. 45 (33, 41–65) s; P = 0.56, but the number of oesophageal intubations was significantly lower when using the suction laryngoscope [4/24 (16.7%) vs. 12/24 (50.0%); P = 0.04].

Conclusions

In a model of severe simulated airway haemorrhage, employing a suction laryngoscope significantly decreased the likelihood of oesophageal intubations in physicians with occasional emergency medical service experience.

Tat-specific binding IgG and disease progression in HIV type 1-infected Ugandans

There are data to suggest that both the humoral and cellular immune responses directed against Tat are beneficial in delaying HIV disease progression. We examined the association between the occurrence of Tat-specific binding antibodies (Abs) and different parameters of HIV-1 disease progression. We generated eight Tat proteins, derived from HIV-1 subtypes A, B, C, and D, and circulating recombinant form CRF01_AE. These proteins were used to screen for Tat-specific binding Abs by an ELISA. Using five Tat proteins, we investigated whether the occurrence of Tat-specific Abs within 2 years after seroconversion for the majority, affected disease progression over time among 126 participants using survival analysis and rate of CD4 decline. Of these, 52 participants with a sample at 1.5 and 4.5 years after seroconversion were further examined to study the effect of Tat-specific Ab loss or maintenance on disease progression. Finally, using all the eight Tat proteins, we also investigated whether specific Abs to these Tat proteins among 48 participants, grouped as rapid progressors (RP, n = 26) and long-term survivors (LTS, n = 22) according to their CD4 decline over time, affected disease progression. Survival analysis did not reveal any evidence of protection from progression by Tat-specific Abs. Comparison of rate of CD4 declines between individuals with and without Abs to any Tat protein showed only a small and borderline significant advantage of having Tat-specific Abs (p = 0.043). There was no correlation between either loss or maintenance of Tat-specific Abs and disease progression. Comparison of LTS with RP showed no evidence that Tat-specific Abs slows participants' disease progression. This study showed no evidence of a protective effect of having Tat-specific Abs among these Ugandan subjects.
