Impaired glucose and lipid metabolism seen in intensive care patients is related to severity of illness and survival.
To relate glucose and lipid metabolism to the severity of illness and survival in critically ill patients. ⋯ In a sample of unselected critically ill patients indices of both glucose and lipid metabolism were found to be related to the severity of illness as well as to the occurrence of sepsis and survival.

Randomized Controlled Trial Comparative Study Clinical TrialCost of ICU sedation: comparison of empirical and controlled sedation methods.
A randomised crossover study was undertaken to compare the quality and cost of controlled versus empirical sedation with midazolam in critically ill patients. Patients (n = 40) entering the ICU were enrolled provided they satisfied the strict entry criteria. During 90 hours of midazolam sedation, patients received randomly allocated 10-hour periods of controlled or empirical sedation. ⋯ In a separate study on 352 patients, a cost-benefit analysis of controlled sedation with midazolam or propofol infusion or bolus injections of morphine plus diazepam showed that the quality of sedation achieved with propofol was superior to the other two regimens and that, with morphine plus diazepam, the quality of sedation was unacceptably poor. Although the direct purchase price of propofol was higher than that of other agents, the total cost of sedation with propofol was lower than that for midazolam for short-term intensive care (less than 24 hours) and comparable to midazolam for longer-term use. However, indirect benefits of sedation with propofol include a much shorter ICU stay with the attendant reduced nursing costs and greater throughout the patients, and this more than compensates for the higher purchase price of the agent.

Comparative StudyPrevention of atmospheric contamination during isoflurane sedation.
With a view to minimising staff exposure to exhaled isoflurane which had been used for sedation, we assessed the efficacy of either activated charcoal adsorption or active or passive mechanical scavenging systems in intensive care units (ICUs). Personal monitoring revealed minimal exposure of staff to the sedating agent. ⋯ The activated charcoal adsorbers functioned highly efficiently for at least 12-hour periods. With simple scavenging techniques, atmospheric isoflurane contamination during sedation with the agent remains well within an acceptable range and is unlikely to pose a health risk to nursing and medical staff.

Chest tubes are placed to empty the pleural space of air or fluid which prohibits full lung expansion. The function of these tubes is dependent on adequate placement, effective drainage and frequent re-evaluation of the patient and the chest drainage system. Knowledge of the principles of chest tube drainage is important to evaluate adequately the function of a tube thoracostomy.
