A new patient registration method for intensive care department management.
A new method to describe intensive care department performance is presented. The method is a complication of available administrative and medical data, completed with a severity of illness measure (Acute Physiology And Chronic Health Evaluation, APACHE) and the registration of nursing care intensity. The development of this latter patient stratification system (Intensive Care Activity Score, INCAS) is described. The performance of the method is demonstrated by a study of 200 consecutive admissions.

After a brief review of the supraspinal and spinal effects of morphine, the reference substance for studies on analgesia, the authors expose a synthesis of the recent literature regarding neurotransmitter involvement in pain perception and transmission. From these data, some future prospects for pain treatment research are identified.

Randomized Controlled Trial Comparative Study Clinical TrialThe use of midazolam and diazepam for sedation following aorto-coronary bypass surgery.
The new water-soluble benzodiazepine midazolam was compared in a randomized study to diazepam for postoperative sedation in fifty patients following aortocoronary bypass surgery with a sufentanil-anesthesia. Midazolam and diazepam were administered intravenously in repeated doses in conjunction with an opioid infusion (piritramide) from the end of surgery during a twelve-hour study period, patients being artificially ventilated. Midazolam scored better than diazepam for quality of sedation and cardiovascular stability during the period of mechanical ventilation and for respiration during the weaning period and after extubation, although no difference was found in weaning time from artificial ventilation and time of extubation. ⋯ The administration of a loading dose of midazolam 5 mg caused a slight, transient decrease in mean arterial pressure. Midazolam appeared to be a more effective sedative agent than diazepam for short-term administration during mechanical ventilation. No evidence of cumulation and prolonged recovery was seen.

During a consecutive period of 24 months, 244 patients with a major trauma were admitted to the Intensive Care Unit. From this pool of patients 60 consecutively were selected who did fulfill the selected criteria. ⋯ We could conclude that no currently used diagnostic test may be seen as an accurate prediction of patients who still develop morbidity or mortality from cardiac contusion. Data from the literature suggest that at present only radionuclide angiography, direct hemodynamic measurement with construction of a Starling curve, and/or 2D-echocardiography may be useful in the identification of the patients at the greatest risk and predictive of the severity of the myocardial injury.

Randomized Controlled Trial Comparative Study Clinical TrialCryoanalgesia for post-thoracotomy pain relief.
A randomized study comparing the postoperative requirements of narcotics of three groups of patients (Group I: no analgesia; Group II: internal intercostal nerve block; Group III: cryoanalgesia) was conducted. This study was performed in order to assess the efficiency of cryoanalgesia versus internal intercostal nerve block to obtain pain relief after thoracotomy. Regarding post-operative narcotic requirements (Piritramide-Dipidolor), there was no significant difference between Group I and Group II patients, but patients from Group III required a significantly lower amount of narcotics during the first 36 postoperative hours (p less than 0.01). We conclude that, although cryoanalgesia does not provide complete post-thoracotomy pain relief, it is however an easy and safe method and is more efficient than internal intercostal nerve block for pain relief after thoracotomy.
