Randomized Controlled Trial Comparative Study Clinical Trial
[Etomidate using a new solubilizer. Experimental clinical studies on venous tolerance and bioavailability].
Pain following intravenous injection as well as thrombophlebitis are substantial side effects of etomidate that have been reported from the first clinical study (1972-1973) onwards. Investigations of our own and by Gran et al. have pointed out that injectable etomidate with intralipid as a solvent removes side effects without impairing the good hypnotic action. The idea of using a lipid emulsion as a solvent was presented a few years later, inducing two further studies. ⋯ The same results have been obtained in the study with volunteers. CONCLUSION. Two unpleasant side effects of etomidate, pain on injection and postoperative thrombophlebitis, were abolished by the solvent "lipid emulsion".

Anesthesiologists have always played a leading role in research into pain and its treatment. Their efforts, however, have been focused on acute or postoperative pain problems. It was the American anesthesiologist John J. ⋯ Organizational skills are also needed for efficient running of multidisciplinary pain treatment facilities. Clinical practice in surgical anesthesia means that anesthesiologists are experienced in interdisciplinary work and familiar with the advantages and dangers of team work. Despite international acceptance of the multidisciplinary approach to chronic pain, there is still a lack of appropriate facilities in the German-speaking countries, and we consider it important that anesthesiologists commit themselves to increasing general awareness of what is needed.

Randomized Controlled Trial Comparative Study Clinical Trial
[Continuous application of morphine is more effective than a bolus administration in the postoperative analgesia and sedation of children].
In ventilated children the cardiorespiratory and metabolic reserve capacities can be extremely limited. Therefore, these children have low thresholds of tolerance for additional stress factors. One of the most obvious aims in the critical postoperative period after heart surgery in children is protection of the cardiorespiratory system against stress reactions. ⋯ Continuous application of morphine was more effective in sparing VO2 than bolus injections in ventilated children after cardiac surgery. We conclude that continuous application of morphine represents stress prevention whereas bolus application of morphine is stress therapy. From the clinical point of view it is more effective to prevent than to treat pain and other stress factors in pediatric patients.

In patients with multiple injuries, the development of permeability edema can be assumed. However, no uniform shape of this fluid accumulation can be found even in the presence of severe injuries. Based on the first clinical observations, our aim was to search for correlations between the development of extravascular lung water (EVLW) and the individual injury pattern in severely traumatized ICU patients. ⋯ Increase of EVLW at a later time (day 7), as observed in groups B and C, is possibly the expression of a mediator and activator-induced "septiformal" injury of the microvascular endothelium. This may be caused by the underlying massive peripheral soft-tissue trauma. Specific elevations of EVLW subsequent to the individual injury pattern can indicate that that process has begun and is responsible for the origin of the microvascular injuries.
