Comparative Study
Prevalence of a training module for difficult airway management: a comparison between Japan and the United Kingdom.
To examine the education of trainees with regard to difficult airway management, we sent a questionnaire to all 89 Japanese University Departments of Anaesthesia (to be answered by a person who was responsible for teaching trainees) and all 280 Royal College of Anaesthetists' Tutors in the UK. The presence or absence of a formal training module for difficult airway management, timing and methods of training, types of airway devices that should be taught, and tutors' expertise with various techniques and devices were surveyed. Sixty-seven of the 89 Japanese tutors (75%) and 167 of 280 UK tutors (60%) replied to the questionnaire. ⋯ In six Japanese departments (9%) and 115 (69%) UK departments, equipment for percutaneous transtracheal ventilation was readily available. Airway devices and techniques that tutors considered necessary to be mastered in the first 2 years of training, differed considerably between Japan and the UK, with notable differences in the use of gum elastic bougies and awake intubation. A training module for difficult airway management is often not provided and equipment for emergency transtracheal ventilation is often unavailable in both countries.

Randomized Controlled Trial Clinical Trial
Low-dose bupivacaine-fentanyl spinal anaesthesia for transurethral prostatectomy.
We evaluated the effect of low-dose bupivacaine plus fentanyl administered intrathecally in elderly patients undergoing transurethral prostatectomy. Patients were randomly assigned to one of two groups. Group F received plain bupivacaine 4 mg with 25 micro g of fentanyl and sterile water to a total of 1.5 ml, and Group B received only 0.5% plain bupivacaine 7.5 mg for spinal anaesthesia. ⋯ The mean level of motor block was higher and the duration of motor block was longer in Group B (p < 0.0001). Hypotension and shivering were significantly more common in Group B (p < 0.05). The addition of fentanyl 25 micro g to plain bupivacaine 4 mg provides adequate analgesia for transurethral prostatectomy with fewer side-effects in elderly patients when compared with the conventional dose of bupivacaine.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the effect of two anaesthetic techniques on surgical conditions during gynaecological laparoscopy.
In a prospective, randomised, controlled trial, we compared the effects of two anaesthetic techniques on surgical conditions during day-case, gynaecological laparoscopic procedures in 40 female patients. Patients were allocated randomly to two groups, either to breathe spontaneously through a laryngeal mask airway or to receive a neuromuscular-blocking agent (NMB) and have the lungs ventilated via a tracheal tube. We then measured the number of attempts of Verres' needle insertion, initial intra-abdominal pressure, time to reach a steady 15 mmHg (1.97 kPa) of intra-abdominal pressure, adequacy of the pneumoperitoneum, operative view and duration of operation. ⋯ The adequacy of the pneumoperitoneum for trocar placement was better in the NMB group. We conclude that the anaesthetic technique of spontaneously breathing through a laryngeal mask airway reduces total operation time. However surgeons should be aware of the different abdominal pressure patterns produced by each anaesthetic technique, and anaesthetists must consider the implications of the anaesthetic technique on surgical safety.
