[Practical training for paramedics : Transformation at the Leipzig University teaching hospital]

BACKGROUND

The "Notfallsanitätergesetz" (the law pertaining to paramedics), which came into effect in January 2014, has fundamentally changed the training of health personnel in German prehospital emergency medicine. The apprenticeship now takes 3 years including 720 h of practical training in eligible hospitals. To date, however, there has been little experience of how the contents of the guidelines for practical training ("Ausbildungs- und Prüfungsverordnung") can be reasonably applied in the teaching hospitals.

METHODS

In a total of nine interdisciplinary working group meetings between October 2014 and June 2016, we developed a curriculum concerning the practical training of paramedics to implement the contents of the guidelines for practical training in a didactically and an organizationally meaningful way.

RESULTS

The implementation of the practical training of paramedics is an excellent chance for the teaching hospitals to contribute to higher quality prehospital emergency medicine. Otherwise, the teaching hospitals face an organizational and personal effort that is not to be underestimated. Thus, a modular curriculum constitutes the possibility of standardizing practical training and simultaneously reducing the time and expenditure for the participating hospitals.

CONCLUSION

The development of a unique curriculum for the practical training of paramedics may contribute to standardized, high-quality, and cost-efficient training.

[Mechanically circulatory support devices--management of typical emergencies]

The use of mechanically circulatory support devices (MCS) will become increasingly important as a therapy option in patients with end-stage heart failure, and emergency physicians will more frequently encounter MCS patients in the next few years. However, emergency management in MCS patients has not yet been standardized. In the following article, common MCS devices are presented and typical emergencies associated with MCS devices are discussed. Furthermore, we try to give recommendations for the management of MCS patients in an emergency situation and present an algorithm in order to facilitate a structured and timely efficient evaluation of the MCS patient.

Acute type A aortic dissection: characteristics and outcomes comparing patients with bicuspid versus tricuspid aortic valve

OBJECTIVES

The aim of this study is to investigate the clinical characteristics and postoperative outcome of patients with a bicuspid aortic valve (BAV) suffering acute dissection in comparison with their tricuspid peers.

METHODS

Between 1995 and 2011, 460 consecutive patients underwent emergency repair for acute type A aortic dissection. In 379 patients without connective tissue disease, the aortic valve morphology could clearly be specified (91.6% tricuspid and 8.4% bicuspid).

RESULTS

At the time of dissection, patients with a bicuspid valve were younger (46.7 ± 13 vs 61.6 ± 12 years, P < 0.001) with the entry tear more often located in the root compared with those with a tricuspid valve (bicuspid: 31.3% vs tricuspid: 6.3%, P < 0.001). Consequently, surgical repair warranted root replacement in 93.8% of bicuspid vs 28.8% of tricuspid valve patients (P < 0.001). The leading pathology was medial necrosis/degeneration in bicuspid and atherosclerosis in tricuspid patients (P = 0.166). Hospital mortality was 20.3% and not significantly different between the two valve morphologies, even despite the younger age of bicuspid patients: 28.1% among bicuspids vs 19.6% among tricuspids (P = 0.255). Survival after discharge was 63.3% at 10 years for all patients. BAV patients had a significantly better survival with 100% at 10 years compared with 60.2% in tricuspid valve patients (P = 0.011). Mean follow-up among survivors was comparable for bicuspid and tricuspid patients (3.7 and 4.1 years, respectively).

CONCLUSIONS

Patients with BAV have a distinctive dissection pattern with the entry tear frequently located in the aortic root and-despite their younger age-are subject to substantial hospital mortality. For bicuspid patients suffering from dissection, composite root replacement yields an excellent outcome equal to an age- and gender-matched normal population.

Long-term survival after composite mechanical aortic root replacement: a consecutive series of 448 cases

OBJECTIVE

To determine the effect of different etiologies on the outcome and mortality after mechanical composite aortic root/ascending replacement.

METHODS

From February 1998 to June 2011, 448 consecutive patients (358 men, age, 52.8 ± 12.3 years) underwent composite mechanical aortic root replacement. Of these 448 patients, 362 (80.8%) were treated for degenerative/atherosclerotic root/ascending aortic aneurysm (287 men, age, 53.0 ± 12.1 years), 65 (14.5%) for emergent acute type A aortic dissection (49 men, age, 51.0 ± 13.1 years), and 21 (4.7%) for active infective endocarditis (20 men, age, 46.5 ± 13.6 years); 15% (n = 68) were reoperative or redo procedures.

RESULTS

The overall hospital mortality after composite root/ascending replacement was 6.7% (n = 30). It was 3.9% (n = 14) after elective/urgent aneurysm replacement, 20.0% (n = 13) after emergency repair for acute type A aortic dissection, and 14.3% for active infective endocarditis (n = 3). The overall 1-year mortality--as a measure of operative success--was 5.2% (n = 19) after elective/urgent degenerative/atherosclerotic root/ascending aortic aneurysm repair, 21.5% (n = 14) after emergency repair for acute type A aortic dissection, and 14.3% (n = 3) after active infective endocarditis (degenerative/atherosclerotic root/ascending aortic aneurysm vs acute type A aortic dissection, P = .03; degenerative/atherosclerotic root/ascending aortic aneurysm vs active infective endocarditis, P = .08; acute type A aortic dissection vs active infective endocarditis, P = .8). Long-term survival was 88.3% at 5 years and 72.2% at 10 years, with a linearized mortality rate after 30 days of 2.5%/patient-year. Long-term survival after surgery for acute type A aortic dissection and active infective endocarditis was 72% and 72.3% at 5 years and 64.9% and 62% at 10 years, respectively, with a linearized mortality rate of 2.6%/patient-year for acute type A aortic dissection and 3.7% for active infective endocarditis. Survival after composite root replacement after the first year paralleled that of an age- and gender-matched population, regardless of the etiology. Women appeared to have less favorable longevity.

CONCLUSIONS

Composite root replacement remains a versatile choice for various pathologic features with excellent longevity and freedom from reoperation and should be strongly considered if conditions for valve-sparing repair are less than perfect.
