Comparative StudyThe cost of an intensive care unit: a prospective study.
The cost of intensive care for patients admitted to the ICU were estimated. Patients suffering from severe combined acute respiratory and renal failure who required mechanical ventilation and renal replacement therapy (SCARRF-D) cost per day significantly more than non-renal patients (pounds 938 compared to pounds 653 per patient respectively) and their average length of stay in hospital is nearly 4 times as long (28.8 compared to 7.6 days respectively). Approximately 44% of the total cost was staff related (28% for the provision of nurses and 16% for the rest). Retrieving information related to cost was difficult, time consuming and labour intensive.

Prognostic significance of early intracranial and cerebral perfusion pressures in post-cardiac arrest anoxic coma.
The prognosis of prolonged cardiac arrests is generally related to brain damage due to the cerebral anoxia. A neurological worsening leading to irreversibility is sometimes associated with an increase in intracranial pressure. We studied for 5 years the early intracranial and cerebral perfusion pressures in 84 patients with deep anoxic coma after cardiac arrest. ⋯ Moreover, none of the patients showing intracranial peak pressures over 25 mmHg survived without after-effects. It is clear that many patients suffer early periods of high intracranial pressures and low cerebral perfusion pressures leading to a bad neurological prognosis. Intracranial pressure monitoring may allow assessment of patients' neurological status and prognosis after cardiac resuscitation.

Injurious sleep behavior disorders (parasomnias) affecting patients on intensive care units.
There are no previous reports on parasomnias (sleep behavior disorders) affecting patients on intensive care units (ICUs). During 8 years of clinical practice, we evaluated over 200 adults with complaints of injurious, sleep-related behaviors, 20 of whom had ICU admissions while their parasomnias had been active and generally undiagnosed/untreated. Mean age during ICU confinement was 62.8 (+/- SD 13.1) years; 85.0% (17/20) were males. ⋯ The polysomnographic studies were diagnostic for the REM sleep behavior disorder (vigorous dream-enactment during rapid eye movement [REM] sleep) in 85.0% (17/20) of patients, and for night terrors/sleepwalking in 15.0% (3/20). Three groups of parasomnia-ICU relationships were identified: i) Parasomnias originating in ICUs, stroke-induced (n = 3); ii) Admission to ICUs resulting from parasomnia-induced injuries: C2 odontoid process fracture and C3 spinous process fracture with severe concussion (n = 2); iii) Parasomnias in patients admitted to ICUs for various other medical problems (n = 15). Physicians should be thus alerted about the possibility of injurious, but usually treatable, parasomnias in ICU patients.
