Randomized Controlled Trial Comparative Study
A comparison of direct and indirect laryngoscopes and the ILMA in novice users: a manikin study.
Direct laryngoscopic tracheal intubation using the Macintosh laryngoscope is taught to many healthcare professionals as it is a potentially life-saving procedure. However, it is a difficult skill to acquire and maintain. Several alternative intubation devices exist that may provide a better view of the glottis and require less skill to use. ⋯ The Airtraq and ILMA reduced the severity of dental trauma in both scenarios. The performance of the other devices studied was more variable. Overall, participants found that only the Airtraq was less difficult to use and they were more confident using it compared to the Macinosh laryngoscope.

Interpleural blockade is effective in treating unilateral surgical and non-surgical pain from the chest and upper abdomen in both the acute and chronic settings. It has been shown to provide safe, high-quality analgesia after cholecystectomy, thoracotomy, renal and breast surgery, and for certain invasive radiological procedures of the renal and hepatobiliary systems. ⋯ The technique is simple to learn and has both few contra-indications and a low incidence of complications. In the second of two reviews, the authors cover the applications, complications, contra-indications and areas for future research.

Case Reports
Use of thromboelastography to demonstrate persistent anticoagulation after stopping enoxaparin.
Peri-operative guidelines exist for neuraxial anaesthesia and anticoagulant therapy. We describe the use of thromboelastography to assess the coagulation status of a patient with moderate renal impairment who had been receiving enoxaparin and was being managed in accordance with current recommendations. This report demonstrates that current guidelines for discontinuing treatment with enoxaparin may not allow a sufficient safety margin in all patient groups and that thromboelastography is a useful tool in such situations.
