BACKGROUND Studies on the effects of anaesthesia on event-related potentials and long latency auditory-evoked potentials (AEP) are sparse. Both provide information on cortical processing and may have potential as monitors of awareness. We studied the effect of propofol on the event-related potential mismatch negativity (MMN) and the long-latency AEP NI. (More)
We studied the i-gel in 100 elective, anaesthetised patients (55:45 male:female, median age 53 years) assessing: ease of use, airway quality, positioning, seal and complications. First insertion attempt was successful in 86 patients, second attempt in 11 patients, and third attempt in three patients. Fifty three manipulations were required in 26 patients(More)
We report the successful use of a ProSeal Laryngeal mask airway (PLMA) to rescue the airway when emergency tracheal intubation and ventilation of the lungs were impossible after haemorrhage into the neck following carotid endarterectomy, despite evacuation of the clot. The airway was re-established after placement of a PLMA. Fibreoptic examination of the(More)
The prediction of the outcome from coma is of considerable importance to the patients, their relatives and attendant medical staff, and yet current clinical methods lack sensitivity and specificity. Objective investigations can enhance the accuracy of such predictions and are an important adjuvant when reaching decisions to continue or terminate life(More)
We studied the impact of introducing percutaneous tracheostomy to our intensive care unit on the incidence and timing of tracheostomy and on the implications for surgical training. The proportion of patients receiving intensive care who underwent tracheostomy doubled from a median of 8.5% to 16.8% (p < 0.01) following the introduction of the percutaneous(More)
BACKGROUND The ProSeal laryngeal mask airway (PLMA) has been available in pediatric sizes in the UK since 2007. Although several non-UK studies have evaluated PLMAs in children, there are little published data regarding their use in this country. Having decided to introduce the pediatric PLMA into our practice, we chose to prospectively audit the first 100(More)
We studied the i-gel™ in 120 anaesthetised children (92 boys, 28 girls; median (IQR [range]) age (3 -7 [0.4 -13]) years and weight 19 (15-26 [7-35]) kg) to assess efficacy and usability. Insertion was successful on the first/second/third attempt in 110/8/1 children and failed in one child. Median (IQR [range]) insertion time was 14 (9-16 [6-200]) s. Manual(More)
The PA(xpress) phayngeal airway (PA(x)) is a new single use airway device that might be used for airway maintenance during anaesthesia or cardiopulmonary resuscitation. We evaluated the performance of the PA(x) in 103 anaesthetised non-paralysed patients undergoing non-emergency anaesthesia. We recorded success of insertion, quality of airway achieved and(More)
