Psychiatric disorders are observable in Intensive Care Unit. They belong to all the psychiatric field. Their genesis depend on various factors that often work together and are interdependent: organic, demographic, psychological, environmental, procedural, hypnic. They can be considered as risk factors influencing the development of responses to stress (theory of stress).

Outcome of oncology patients in the pediatric intensive care unit.
We evaluated the outcome of oncology patients in the Pediatric Intensive Care Unit (PICU) from a total of 72 consecutive admissions. Severity of illness and quantity of care were measured by the Physiologic Stability Index (PSI) and the Therapeutic Intervention Scoring System (TISS), respectively. The overall mortality was 51% and was especially high in patients admitted for acute organ system failure (OSF)-66%. ⋯ A poor outcome was associated with severe leucopenia (less than 1000 WBC/mm3, 91% mortality), acute renal failure (94% mortality) and central nervous system deterioration (83% mortality). When the outcome was predicted using a quantitative algorithm the observed mortality was significantly higher than the predicted for all admissions with a PSI higher than 5. Improved scoring systems are required to enable characterization of pediatric cancer patients admitted to the PICU.

Review[How painful is long-term ventilation? Considerations on the importance of analgesia within the scope of analgosedation].
The goal of analgesia and sedation in intensive care units is most often achieved using numerous drug combinations, mostly justified by physicians' and nurses' habits instead of rational pharmacological criteria for the choice of drugs and dosages. The present paper aims at defining the analgesic situation of ventilated intensive care patients and concludes from analogy with other, better understood states of pain that the importance of analgesic drugs is frequently overrated. To achieve effective analgesia and sedation in individual patients, the dosage must be titrated to individual needs. The author suggests that standardized baseline analgesia should be used, which enables sedation to be titrated, whereas the opposite is not practicable in clinical routine.

Recent therapeutic advances in inotropic drugs and vasipressors uses allow a reappraisal of their indications during the perioperative period. Non-catecholamines vasopressors, ephedrine and phenylephrine, are particularly suitable for treatment of abrupt peroperative arterial hypotensions as observed during induction of general and medullar anesthesias. Cardiac arrest, peroperative anaphylactoid and toxic accidents are treated with epinephrine. ⋯ Inodilators (enoximone, amrinone and milrinone) ans nex dopaminergic compound (dopexamine) are powerful vasodilators agents to be introduced with care when association of amines and current vasodilators have failed. Finally, arterial pressure has to be maintained with norepinephrine after dopamine failure. Epinephrine remains last chance.

Seven different schemes for analgesic anaesthesia were investigated for their clinical applicability, potential side effects, and impacts on circulation parameters of the systemic and pulmonary (peripheral) circulation as well as on the intracranial pressure. In all, so patients per group were treated. The results revealed different reactions of patients, such as a higher incidence of disturbances of the autonomic nervous system and excitation after medication withdrawal. ⋯ In several instances, a clear increase in the right atrial and the pulmonary arterial mean pressure as well as the intracranial pressure was observed during ketamine/flunitrazepam therapy. The combinations pethidine/promethazine or pethidine/flunitrazepam also showed clear side effects on the circulation and evoked an increase in the intracranial pressure. Fentanyl/midazolam or alfentanil/midazolam treatments were the most favourable combinations for most of the patients who were artificially respirated.
