A national survey on the practice patterns of anesthesiologist intensivists in the use of muscle relaxants.
To determine the practice patterns of anesthesiologist intensivists (with the special certificate of competence in critical care medicine from the American Board of Anesthesiology) in the use of neuromuscular blocking drugs, in the ICU setting. ⋯ This study was created to address the dearth of information regarding actual usage of muscle relaxants in the ICU setting. The survey population was chosen as one with great familiarity in the use of muscle relaxants. The 55% response rate was significantly greater than the expected response rate for a single mailing survey. In the ICU setting, neuromuscular blocking drugs are most frequently used to facilitate mechanical ventilation. The prevalence of vecuronium use is of interest in light of recent case reports of prolonged neuromuscular blockade after long-term vecuronium administration. The low frequency of peripheral nerve stimulator monitoring during muscle relaxation may contribute, in part, to the problem of prolonged blockade after drug withdrawal. Muscle relaxants are not used in the absence of sedation and/or analgesia by this practitioner population.

A computerised system of prediction of death using the Riyadh Intensive Care Program was applied retrospectively over a 17-month period to data collected prospectively on 1155 patients admitted to our intensive care unit. Variables which enable organ failure scores to be generated were recorded daily to make these predictions. ⋯ It is possible that the occurrence of three false predictions of death in the latter part of the series may have been related to a change in our antibiotic policy. We would be unhappy to recommend the general use of a computerised program for prediction of death without careful explanation of its significance and dangers.

All maternity cases in which babies were transferred in-utero (n = 82) or neonatally (n = 273) from the William Smellie Memorial Maternity Hospital to a regional neonatal intensive care unit during 1980-89 were studied to detect changing trends and outcomes. The proportion of babies transferred in-utero has increased and most of these transfers appear to have been justified. ⋯ Perinatal mortality has fallen in line with national rates, mainly due to the decline in mortality of premature babies transferred neonatally. The results do not sustain the argument for further increasing in-utero transfers.

Errors in prescription, administration, delivery and interaction of drugs are likely in children in intensive care units because of the large number of often unfamiliar medications these children receive. We evaluated prospectively the frequency and consequence of drug errors in a large multidisciplinary intensive care unit. There was a mistake in drug prescription, administration, delivery or drug interaction in 2% of medication orders, with 12% of these mistakes causing actual harm to the patient. The frequency of drug errors must be appreciated and due care must be taken in checking and delivering drugs to children in an intensive care unit.

To develop a scoring system for stratifying patients in intensive care units (ICUs) by risk of developing nosocomial pneumonia (NP) and to identify the time period associated with the highest risk. ⋯ ICU patients can be stratified into high- and low-risk groups for NP using a bedside scoring system. Endotracheal intubation, altered mental status, and NG tube are associated with the highest risk of NP during the first 1 to 6 days of their presence after 72 hours of stay in the ICU. After this time period, the risk associated with these factors decreases. Bronchoscopy may be an independent risk factor for NP that has not been previously recognized. This procedure, often done in the ICU for respiratory toilet, may be an avoidable risk in this group of patients.
