In recent years, several factors have led to increasing focus on the meaning of appropriateness of care and clinical performance in the intensive care unit (ICU). The emergence of new and expensive treatment modalities, a deeper reflection on what constitutes a desirable outcome, increasing financial pressure from cost containment efforts, and new attitudes regarding end-of-life decisions are reshaping the delivery of intensive care worldwide. ⋯ Their application has broadened to include ICU performance assessment, individual patient decision-making, and pre- and post-hoc risk stratification in randomised trials. In this paper, we review the popular scoring systems currently in use; design issues in the development and evaluation of new scoring systems; current applications of scoring systems; and future directions.

Randomized Controlled Trial Comparative Study Clinical TrialCaudal morphine in paediatric patients: a comparison of two different doses in children after major urogenital surgery.
We compared the duration of postoperative analgesia and the occurrence of side-effects of two different doses of caudal morphine in children undergoing major urogenital surgery. Fifty-two children aged between 1 and 12 years were randomly selected to receive caudal morphine, either 25 micrograms.kg-1 (Group A) or 50 micrograms.kg-1 (Group B) with 0.5 ml kg-1 of 0.25% plain bupivacaine immediately before surgery. They were monitored for 24 hours in a high dependency area for known complications of epidural morphine. ⋯ The occurrence of vomiting and pruritus was similar in both groups. Urinary retention was not recorded as all children had an indwelling catheter as required by the surgical procedure. We concluded that 25 micrograms.kg-1 of caudal morphine is as effective as 50 micrograms.kg-1 for providing postoperative analgesia in children undergoing urogenital surgery.

Septic shock is a major cause of death among patients in intensive care units. It has a mortality rate of 20% to 80%. The clinical syndrome of septic shock is characterised by hypotension, hyporesponsiveness to vasoconstrictors and volume depletion which will then lead to multiorgan dysfunction and death. ⋯ Inhibition of NO synthase, the enzyme responsible for NO production, has been proposed as a new therapy for septic shock. However, experimental reports have provided conflicting results, demonstrating both beneficial and detrimental effects. A brief review of the role of NO in septic shock and the possible use of NO synthase inhibitors as potential therapeutic agents is presented here.

ReviewContributions of respiratory care practitioners to intensive care: a review.
Through the years, the professional practice of respiratory care has continually evolved to include management of critically ill patients. Although the functions and duties of respiratory care practitioners (RCPs) in this setting may vary across different institutions, it is widely recognised throughout the United States that RCPs contribute importantly to intensive care unit (ICU) outcomes. ⋯ Other ICU activities in which RCPs participate include assisting with bronchoscopy, obtaining haemodynamic measurement, and indirect calorimetry and supporting specialised techniques such as extracorporeal membrane oxygenation (ECMO) and continuous veno-venous haemofiltration and/or haemodiafiltration (CVVH/CVVHD). Based on the demonstrated impact of RCPs and their technical and cognitive training, a continuing role expansion for RCPs in the ICU is expected.

Comparative StudyPredictors of long-term outcome in severe head injury.
Severe head injury is associated with significant morbidity and mortality. We conducted a retrospective study to assess the long-term outcome of these patients using the Glasgow Outcome Score (GOS) and evaluate the variables that might predict outcome. Data were collected from all post-traumatic neurosurgical patients with severe head injury (Glasgow Coma Scale 8 or less) admitted to the Surgical Intensive Care Unit over a 29-month period. ⋯ Patients with a poor outcome (defined as GOS scores of 1 to 3) had a significantly higher mean age, higher Acute Physiology and Chronic Health Evaluation (APACHE) II score and a lower Glasgow Coma Scale than those with a good outcome (GOS 4 to 5). The APACHE II score correlated better with outcome than the Glasgow Coma Scale or age. The APACHE II score may be used to prognosticate the long-term outcome in severe head injury.
