Review[Ethics in preclinical emergency medicine--on the topic of medical futility and resuscitation efforts].
In prehospital emergency medicine, physicians are repeatedly faced with the question of when cardiopulmonary resuscitation (CPR) efforts should be withheld or terminated since they are clearly futile. Here, futile means the goal of saving life cannot be achieved. Determining futility involves qualitative und quantitative aspects. ⋯ Thus, unilateral decisions by emergency physicians to withhold CPR are only justified in special cases when it is obvious that CPR and preservation of life would not be in the patient's interest. When in doubt, resuscitation attempts must be made. The futility of these efforts may emerge later in hospital, or information becomes available regarding the patient's will which justifies an end to therapy.

Review[Introduction of patient-controlled analgesia--an interim report].
In spite of improved therapeutic methods, the number of patients who suffer from moderate or severe postoperative pain remains high at 30 to 70%. It is accepted that improvement of the organization of postoperative pain therapy is a necessary precondition for changing this situation. Therefore, patient-controlled analgesia (PCA) using pain-pumps should be recognized and the effect on the whole postoperative pain therapy of a university clinic observed. ⋯ Because of these fundamental changes, the frequency of the application of pain-pumps increased six-fold within one year. Additionally, rapid pain treatment based on patients' needs increased clearly from 9.2 to 30.8%. The standardized introduction of PCA had an extremely favourable effect on the whole postoperative pain therapy and can thus be wholeheartedly recommended.

To improve the success of blind intubation through a laryngeal mask, Dr. A. I. ⋯ Correct judgement of endotracheal tube position is mandatory. The ILMA has the potential to be used in patients who are difficult to intubate and to substitute the SLMA in "cannot ventilate--cannot intubate" situations. The future will show if the ILMA also will improve emergency airway management by inexperienced personnel, including intubation, as has been shown for the standard laryngeal mask airway in cardiopulmonary resuscitation for ventilation only.

Randomized Controlled Trial Comparative Study Clinical Trial[Is the laryngeal mask a viable alternative to endotracheal intubation in adenoidectomies in children?].
Based on our results and experiences, we consider the laryngeal mask anaesthesia a recommendable alternative to endotracheal intubation anaesthesia for adenotomies in children. Prerequisites with regard to the highest possible safety for the patient are specialist's knowledge, close anaesthesiological-otolaryngological cooperation and continuous clinical and apparative monitoring in order to detect possible accidental dislocations of the laryngeal mask without any delay. Using the laryngeal mask, disadvantages of endotracheal intubation, such as lesions of the vocal cords and damages to the tracheal mucous membrane can be avoided and the total time of narcosis can be reduced on average by about five minutes, particularly by shortening the recovery time of anaesthesia.

Randomized Controlled Trial Clinical Trial[Changes in blood coagulation in treatment with hydroxyethyl starch].
The aim of the study was to investigate the influence on coagulation and platelet function of two 6% medium molecular weight hydroxyethylstarch solutions (HES, MW 200,000, DS 0.5) made of potato (K) and corn (M) starch. Twenty patients undergoing elective vertebral disc surgery were randomly assigned to one of the groups. Haemoglobin, haematocrit, protein concentration, fibrinogen, antithrombin III, factor VIII:C, von-Willebrand-factor, prothrombin time, activated partial thromboplastin time and platelet maximum aggregation and maximum gradient of aggregation (inductors: ADP, epinephrine, collagen and ristocetin) were measured before infusion and 30, 240 minutes and one day after infusion. ⋯ The infusion of a medium molecular weight solution is an effective and cost-saving method in volume therapy. Despite the physicochemical differences of the two HES solutions, there were no clinically apparent effects on coagulation and platelet function. Both preparations of HES up to a volume of 1,000 ml can be used equally in the clinical setting.
