Multicenter Study
Determinants of hospital costs associated with traumatic brain injury in England and Wales.
Using data from the Trauma Audit Research Network, we investigated the costs of acute care in patients > or = 18 years of age hospitalised for traumatic brain injury between January 2000 and December 2005 in England and Wales. Traumatic brain injury patients were defined and stratified using the Abbreviated Injury Scale. A total of 6484 traumatic brain injury patients were identified; 22.3% had an Abbreviated Injury Scale score of three, 38.0% of four and 39.7% of five. ⋯ In total 23.7% of the patients died before discharge. Hospitalisation costs averaged 15,462 pounds sterling (SD 16,844 pounds sterling). Costs varied significantly by age, Glasgow Coma Score, Injury Severity Score, coexisting injuries of the thorax, spine and lower limb, hospital mortality, availability of neurosurgical services, and specialty of attendants seen in the Accident and Emergency department.

Multicenter Study
A prospective observational study of ICU patient position and frequency of turning.
Positioning and turning critically ill patients may be beneficial but there are little data on current practice. We prospectively recorded patient position every hour over two separate days in 40 British intensive care units and analysed 393 sets of observation. Five patients were prone at any time and 3.8% (day 1) and 5% (day 2) were on rotating beds. ⋯ The average time (SD) between turns was 4.85 (3.3) h. There was no significant association between the average time between turns and age, weight, height, gender, respiratory diagnosis, intubated and ventilated, sedation score, day of week or nurse:patient ratio. There was a significant difference between hospitals in the frequency with which patients were turned.

The use of N-terminal pro-B type natriuretic peptide in a pre-operative setting to predict left ventricular systolic dysfunction on echocardiogram.
Heart failure is a major risk factor for adverse postoperative events following non-cardiac surgery. The use of transthoracic echocardiogram as a pre-operative investigation to assess cardiac dysfunction has limitations in this setting. The N-Terminal fragment of B-Type natriuretic peptide (NT proBNP) has been used in screening for heart failure. ⋯ In terms of pre-operative screening, a NT proBNP of <38.2 pmol x l(-1) had a 100% negative predictive value in predicting patients with normal left ventricular systolic function and would have prevented the requirement for echocardiogram in 43% of pre-operative patients. NT proBNP was superior to electrocardiological and clinical criteria for detection of a normal echocardiogram. This may have significant impact in the pre-operative assessment of patients undergoing non-cardiac surgery.

Adults who experience intra-operative awareness can develop disturbing long-lasting after-effects, such as daytime anxiety, sleep disturbances, nightmares, flashbacks and, in the worst case, a post-traumatic stress disorder (PTSD). It is unknown whether intra-operative awareness has a similar psychological impact in children. We designed the present study in order to evaluate the incidence of psychological symptoms in children who had either confirmed or possible intra-operative awareness. ⋯ In contrast with what has been reported in adults, these children claimed not to have experienced major pain, terror or helplessness during their surgery. Despite the small sample size, the results of the present study suggest that children suffer less psychological sequelae than adults following intra-operative awareness. This may be due to the fact that the children reported less frightening intra-operative sensations as compared with the adults, and had less understanding of the anaesthesia procedure, and this may have influenced their appraisal of their awareness and protected them from the full impact of this potentially traumatic experience.

We describe the anaesthetic management of a 21-year-old lady with central core disease for elective Caesarean section. Central core disease is characterised by muscle weakness, skeletal deformities and susceptibility to malignant hyperthermia. ⋯ The authors believe there is no previous report of propofol and remifentanil being used in these circumstances. A short review of central core disease and its anaesthetic implications is provided.
