Currently, approximately 100 000 helicopter emergency medical service (HEMS) missions for patients are undertaken in Germany each year. Compared to the early years, risk has reduced significantly, but is still higher than commercial aviation or other airborne operations. ⋯ The present study is the largest on HEMS accidents and the only one analysing an entire 40-year time course beginning with inception. In comparison to previous data, a significantly lower accident rate per 10 000 missions was found. Gathering data on the early years is nearly impossible, and further analysis is required to calculate the risk of fatality or identify injury patterns.

Randomized Controlled Trial Comparative Study
Nasotracheal intubation using the Blind Intubation Device in anaesthetised adults with Mallampati class 3: a comparison with the Macintosh laryngoscope.
We hypothesised that the Blind Intubation Device (BID) would be effective for nasotracheal intubation (NTI) in anaesthetised adults with Mallampati class 3. We also hypothesised that BID may cause less haemodynamic changes due to the avoidance of direct stimulation induced by the Macintosh blade. ⋯ In adults with Mallampati class 3, NTI using the BID caused an attenuated haemodynamic response and showed a higher success rate on the first attempt without increasing adverse events. The BID is an effective alternative to the Macintosh laryngoscope for NTI in anaesthetised adults with Mallampati class 3.

Meta Analysis
Comparison of video laryngoscopes with direct laryngoscopy for tracheal intubation: a meta-analysis of randomised trials.
Video laryngoscopes have been introduced in recent years as an alternative choice to facilitate tracheal intubation. We conducted a meta-analysis to assess their value when compared with direct laryngoscopy. ⋯ Video laryngoscopes are a good alternative to direct laryngoscopy during tracheal intubation. The advantage seems to be more prominent when difficult intubation is encountered.

Randomized Controlled Trial Comparative Study
Comparison of the PaO2/FiO2 ratio in sternotomy vs. thoracotomy in mitral valve repair: a randomised controlled trial.
Cardiac surgery through a thoracotomy using one-lung ventilation (OLV) is thought to be associated with worse postoperative pulmonary gas exchange than sternotomy using two-lung ventilation (TLV), but this has not been confirmed yet. We, therefore, compared postoperative pulmonary gas exchange after mitral valve repair between sternotomy (group TLV) and thoracotomy (group OLV). ⋯ Not registered.

Iron deficiency is the commonest cause of anaemia. It is apparent preoperatively in cardiac surgery patients and may influence transfusion requirements. In addition, iron deficiency per se is associated with fatigue. ⋯ Preoperative iron deficiency is frequent among cardiac surgery patients and is associated with anaemia, higher transfusion requirements and postoperative fatigue.
