Review Case ReportsPalatopharyngeal wall perforation during Glidescope intubation.
We report a case of palatopharyngeal wall perforation during intubation with a GlideScope laryngoscope. The likely mechanism was advancing and rotating the endotracheal tube against a taut palatopharyngeal fold. This was missed during the initial laryngoscopy, because there is a potential blind-spot in the oropharynx when attention is focused on the GlideScope" monitor Fortunately, there were no sequelae other than minor bleeding and a mild sore throat and no surgical intervention was necessary. The use of unnecessary force during the endotracheal tube insertion, the use of too large a laryngoscope blade and the use of a rigid stylet could possibly also have been contributory factors to this complication.

Randomized Controlled TrialEvaluation of the efficacy of magnesium sulphate as an adjuvant to lignocaine for intravenous regional anaesthesia for upper limb surgery.
Several additives have been combined with local anaesthetics for intravenous regional anaesthesia to improve block quality, analgesia and to decrease tourniquet pain. Magnesium sulphate is one potential additive. This prospective, randomised, double-blinded study was conducted in 30 ASA physical status I or II patients undergoing upper limb surgery under tourniquet. ⋯ There was a statistically significant difference in visual analogue scale for tourniquet pain at 10 and 30 minutes after tourniquet inflation (lower in group M). These findings indicate that magnesium sulphate added as an adjuvant to lignocaine hastens the onset of sensory and motor block and decreases tourniquet pain. However there is increased incidence of transient pain on injection if magnesium sulphate is added.

Randomized Controlled TrialEfficacy of low dose levobupivacaine (0.1%) for axillary plexus block using multiple nerve stimulation.
The purpose of this study was to investigate if low doses of levobupivacaine (0.1%) produce complete sensory blockade in preoperative axillary brachial plexus block and to compare the effect of different doses of levobupivacaine on sensory and motor blockade. A total of 110 patients scheduled for elective forearm or hand surgery were randomly allocated to receive 36 ml or 72 ml of levobupivacaine 0.1% or 36 ml of levobupivacaine 0.25%. In each group, volumes were equally distributed in the four nerve territories. ⋯ Complete sensory block was obtained in 94.4% of patients receiving 36 ml of levobupivacaine 0.1%, 92.1% of those receiving 72 ml of levobupivacaine 0.1%, and 97.1% of those receiving 36 ml of levobupivacaine 0.25%. There was no significant difference either in the onset of the sensory and motor block or duration of the sensory and motor block. This study demonstrates that 36 ml of levobupivacaine 0.1% (36 mg) is as effective as higher doses and volumes in axillary brachial plexus blockade.

Comparative StudyComparison of stress in anaesthetic trainees between Hong Kong and Victoria, Australia.
A postal survey was sent to anaesthetic trainees in Hong Kong and Victoria, Australia to compare work-related stress levels. Demographic data were collected. Anaesthetist-specific stressors, Maslach Burnout Inventory and Global Job Satisfaction scores were used for psychological testing. ⋯ Despite the complex nature of stress, its antecedents and manifestations, an inverse relationship between emotional exhaustion and job satisfaction was evident in correlation analysis (P < 0.001). This survey suggests that stress was present in some trainees in both areas. Hong Kong trainees may benefit from local development to address mental wellbeing as being important to fulfil this highly competitive training program.
