Multicenter StudyA survey of anaesthetists' perspectives of communication in the operating suite.
We surveyed 222 anaesthetists attending a University of Western Australia conference (n = 110) and two public hospitals in Perth (n = 112) by anonymous questionnaire in March 2006 regarding communication issues in the operating suite. Forty-one percent (n = 92) responded. Questions concerned communication skills, experiences of good and poor communication and relationship to outcome, attitudes to music and communication courses. ⋯ Sixty-four percent of respondents would attend a communications course voluntarily, with implementation of a compulsory communications course supported by 45%. Most anaesthetists surveyed used staff first names and 94% believed poor communication caused procedural delay. The data suggest that further work is required to improve communication in the stressful operating room environment, particularly at the surgeon/anaesthetist interface.

Comparative StudyDose requirements for propofol anaesthesia for dental treatment for autistic patients compared with intellectually impaired patients.
We had clinical grounds to suspect that patients with autism had greater propofol requirements during dental procedures than patients with intellectual impairment without autism. This hypothesis was tested by an audit of a standard anaesthetic technique. The audit was approved by our Hospital Ethics Committee. ⋯ The propofol infusion rates of the intellectually impaired group showed significant decline with age (propofol rate of requirement mg x kg(-1) x h(-1), mean [SD]): < six years 13.6 (3.6), seven to 19 years 9.5 (3.0) (P = 0.008 cf < six years group), > 19 years group 8.5 (2.4) (P = 0.001 cf < six years group). The propofol requirement was greater in the autism group than in the intellectual disability group, and the proportion of the cases where bolus propofol administration was needed after induction was significantly higher in the autistic patient group than in the intellectually impaired patients (P < 0.002). This suggests that autistic patients have greater propofol requirements for anaesthesia during ordinary dental treatment compared with intellectually impaired patients.

Changes in serum procalcitonin and C-reactive protein following antimicrobial therapy as a guide to antibiotic duration in the critically ill: a prospective evaluation.
Serial procalcitonin is reported to be useful to titrate duration of antibiotic therapy in the non critically ill patient with pneumonia. The aim of this study was to examine the relationship between antibiotic therapy and serial serum procalcitonin concentrations in a cohort of critically ill septic patients and examine for any differences between culture positive (CP) and culture negative (CN) sepsis. Seventy-five critically ill patients with suspected sepsis were enrolled in this prospective observational study. ⋯ The mean procalcitonins in the relapsed subgroup were lower than those in the remission subgroup (P = 0.02). Therapy for proven or presumed infections was associated with declining serum procalcitonin and C-reactive protein in critically ill septic patients. The marked variability and overlap in plasma profile of these markers between CP and CN sepsis makes it difficult to define a nadir plasma concentration at which one can recommend discontinuation of antibiotic therapy.

Comparative StudyIn situ simulation-based team training for post-cardiac surgical emergency chest reopen in the intensive care unit.
Emergency chest reopen of the post cardiac surgical patient in the intensive care unit is a high-stakes but infrequent procedure which requires a high-level team response and a unique skill set. We evaluated the impact on knowledge and confidence of team-based chest reopen training using a patient simulator compared with standard video-based training. We evaluated 49 medical and nursing participants before and after training using a multiple choice questions test and a questionnaire of self-reported confidence in performing or assisting with emergency reopen. ⋯ In a multiple choice question out of 10, participants improved by a mean of 1.9 marks with manikin-based training compared to 0.9 with video training (P = 0.03). On a questionnaire out of 20 assessing subjective levels of confidence, scores improved by 3.9 with manikin training compared to 1.2 with video training (P = 0.002). Simulation-based training appeared to be at least as effective as video-based training in improving both knowledge and confidence in post cardiac surgical emergency resternotomy.

Case ReportsSuperficial cervical plexus block combined with auriculotemporal nerve block for drainage of dental abscess in adults with difficult airways.
We report our use of a superficial cervical plexus block to manage three adults who presented for drainage of dental abscesses. All patients had difficult airways related to severe trismus (preoperative inter-incisor distance < or = 1.5 cm). ⋯ The blocks were successful in all three cases with minimal requirement for supplemental analgesia. We recommend the consideration of superficial cervical plexus block, and if necessary an auriculotemporal nerve block, for the management of selected patients with difficult airways who present for drainage of dental abcesses.
