OBJECTIVE To assess whether the use of a spermatic-cord block contributes any additional analgesia to that of a conventional analgesic regimen in day-case testicular surgery. PATIENTS AND METHODS In a randomized, double-blind controlled study, 48 patients undergoing day-case testicular surgery received general anaesthesia together with fentanyl and(More)
OBJECTIVE To determine whether outcomes and costs in children undergoing cardiac surgery are affected by the method of postoperative pain management. DESIGN Retrospective, case control. SETTING Tertiary care children's hospital in a university setting. PARTICIPANTS Two groups of children undergoing cardiac surgery for palliation or repair of(More)
In 554 anaesthetised patients, the times taken to separately palpate and identify each of the carotid, radial, brachial and femoral pulses were recorded. The patients were divided into three groups based on the form of airway management chosen (tracheal tube, facemask or laryngeal mask airway). Our results demonstrate that in the operating theatre(More)
The bleeding times of five volunteers were assessed individually by each of 12 observers. The reliability of the measurements obtained was examined by comparing statistically the variability between subjects and between observers. This variability was found to be similar for both groups. Consequently, we suggest that the bleeding time estimation is an(More)
Laryngeal mask airway cuff inflation pressures were measured when inflated with the same volume of gas firstly in free space and then in position in the pharynx. A large difference in these pressures was observed and this was related to pharyngeal mucosal perfusion pressure. This study shows that it may be easy to produce pressures on the pharyngeal mucosa(More)
We have examined the raw EEG activity and auditory evoked responses (AER) in 35 children, aged 3 days to 13 yr (median 1.5 yr), undergoing general anaesthesia for routine surgery. Binaural stimuli were presented at a frequency of 6.12 Hz and the EEG was recorded and stored using the Northwick Park auditory evoked response software. AER were generated by(More)
