Case Reports
Computed tomographic findings of cerebral fat embolism following multiple bone fractures.
Fat embolism to the lungs and brain is an uncommon complication following fractures. Few reports with descriptions of computed tomographic (CT) findings of emboli to the brain or cerebral fat embolism are available. We report a case of cerebral fat embolism following multiple skeletal fractures and present its CT findings here.

Comparative Study Observational Study
Comparison of results from novice and trained personnel using the Macintosh laryngoscope, Pentax AWS®, C-MAC™ and Bonfils intubation fibrescope: a manikin study.
Indirect laryngoscopes offer improved laryngeal view and higher success rates of intubation, particularly for difficult airways. We hypothesised that: (a) the time required for intubation, overall success rates and ease of intubation with indirect laryngoscopes would be better than with the Macintosh laryngoscope; and (b) novices may achieve higher success rates and intubate faster using indirect laryngoscopes. ⋯ We found that intubation success was more than 85% with all indirect laryngoscopes compared to 69% for the Macintosh laryngoscope. Both C-MAC and Pentax AWS achieved faster intubation times compared to the Macintosh laryngoscope and Bonfils intubation fibroscope for both airway scenarios. Skilled anaesthetists were 33% faster than novices when intubating a difficult airway using Pentax AWS.

Acute pulmonary embolism (PE) is an uncommon but potentially fatal disease. Acute right ventricular failure, which can be demonstrated by echocardiography, is known to be an adverse prognostic factor in patients with acute PE. However, this diagnostic test is not always available in emergency departments and it is also an operator-dependent investigation. This study aimed to investigate whether cardiac troponin I (cTnI) levels could predict clinical outcomes in Chinese patients with PE. ⋯ Elevated cTnI level was associated with a complicated clinical course in patients with acute PE. We suggest that measurements of cTnI levels be used for the early risk stratification of patients with PE in the emergency departments of hospitals.

This study reports our experience of audit and critical incidents observed by paediatric anaesthetics from 2000 to 2010 at a paediatric teaching hospital in Singapore. ⋯ Critical incident reporting has value, as it provides insights into the system and helps to identify active and system errors, thus enabling the formulation of effective preventive strategies. By creating and maintaining an environment that encourages reporting, we have maintained a high and consistent reporting rate through the years. The teaching of analysis of critical incidents should be regarded by all clinicians as an important tool for improving patient safety.

Phantom limb sensations (PLS), phantom limb pain (PLP) and stump pain (SP) are well-recognised postamputation phenomena. However, there is a dearth of related epidemiological data in Asian populations. This study was conducted to fill the information gap. ⋯ The incidence of PLP was 25% in our cohort. Although this is lower than that reported in other studies, it remains significant, as some patients suffered moderate-to-severe pain. The difference in incidence may be due to differences in the ethnic composition and/or indications for amputation in our group. Follow-up and care could improve the outcomes in these patients.
