[Correct positioning of central venous catheters in pediatrics : Are current formulae really useful?]
Correct positioning of a central venous catheter (CVC) tip in pediatric patients is very important. Malpositioning may lead to direct complications, such as arrhythmia and increase the risk of thrombosis, infections, valve failures or pericardial tamponade. ⋯ The benefit of a formula for daily practice is very limited due to the problem of choosing the right insertion point. The recommended insertion depth should be considered as an indicator and a verification of the CVC tip position should be done using an imaging technique.

For cardiac surgery patients who were employed prior to surgery, the return to their professional life is of special importance. In addition to medical reasons, such as pre-existing conditions, the success of the operation or postoperative course and patient-intrinsic reasons, which can be assessed with the Sense of Coherence (SOC) scale by Antonovsky, may also play a role in the question of a possible return into working life. ⋯ Patients with an SOC score < 130 are at greater risk not to return to their professional life after cardiac surgery. The SOC is an easily obtainable score that reliably predicts the probability of return to work after cardiac surgery.

The prevalence of malignant hyperthermia (MH) in Germany is 1:2000-1:3000 and therefore more common than previously assumed, so that anesthesia personnel will more often be confronted with susceptible patients in the clinical setting. After the initial treatment with 2.5 mg/kg body weight dantrolene, further therapy using up to 10 mg/body weight dantrolene can be indicated for 24 h. ⋯ For outpatient anesthesia a stockage of dantrolene is not necessary as long as the use of MH trigger substances in general is strictly avoided. The introduction of Ryanodex® (Eagle Pharmaceuticals, Woodcliff Lake, NJ, USA), a preparation of dantrolene with clearly improved pharmacological properties, in the clinical practice has not yet been realized in Germany.
