Randomized Controlled Trial Comparative Study Clinical Trial
Regional anaesthesia for circumcision in adults: a comparative study.
Penile block (PB) in adults is not a well-recognized technique. The aim of this study was to compare, in a randomized prospective manner, five different techniques of PB in 250 adults undergoing circumcision with regard to anaesthetic quality, complications and postoperative analgesia. Patients were divided into five groups (50 per group) according to the technique used: Group A--"10, 30-13, 30" approach; Group B--the subpubic approach; Group C--subcutaneous ring block; Group D--a combination of frenulum infiltration and the "10, 30-13, 30" approach; Group E--a combination of frenulum infiltration and the subpubic approach. ⋯ The five groups did not differ with regard to adverse effects or time until the onset of postoperative pain when the blocks were successful. It is concluded that good surgical anaesthesia, a low rate of adverse effects and prolonged postoperative analgesia can be achieved by the use of either subcutaneous ring block or a combination of dorsal nerve block (using the "10, 30-13, 30" or the subpubic approach) and infiltration of the frenulum. These approaches to the PB are effective anaesthetic techniques for circumcision in adults.

Randomized Controlled Trial Comparative Study Clinical Trial
Recovery characteristics following induction of anaesthesia with a combination of thiopentone and propofol.
The purpose of this study was to determine the rate and quality of recovery when general anaesthesia was induced with a mixture of thiopentone and propofol, compared with thiopentone or propofol alone. Sixty ASA class I and II women scheduled for out-patient laparoscopic surgery underwent induction of anaesthesia with either (i) thiopentone, (ii) propofol, or (iii) a mixture of the two, in a randomized, double-blind fashion. Anaesthesia was then maintained using nitrous oxide, isoflurane and fentanyl. ⋯ The recovery time between thiopentone and the other two regimes was different (P < 0.05). All three groups experienced equally frequent and severe nausea, headache, tiredness and other side effects during the next 24 hr. It is concluded that induction with a mixture of thiopentone and propofol leads to a similar rate and quality of recovery to that of propofol above.(ABSTRACT TRUNCATED AT 250 WORDS)

The shift to direct entry into residency training from medical school for all graduates will offer new challenges for anaesthesia training programmes. In this paper we argue that it also offers us an opportunity to re-evaluate our current approach to anaesthesia education. Emphasis in the residency programmes should be to provide trainees with clinical experiences and stimulation that will develop the required traditional competencies. ⋯ Faculty development will be required to help the resident pursue these skills of self-evaluation and efficient learning. We believe that incorporation of an experiential curriculum into the residency training programme will achieve the goals listed above and allow maturation of the process of lifelong learning. It will also allow greater achievement of the application of new information to one's practice.

The purpose of this report is to describe the discovery and management of an unanticipated injury during fibreoptic tracheal intubation. A 23-yr-old man sustained blunt cervical, thoracic and abdominal trauma in a motor vehicle accident. He was brought to the operating room for urgent management of his abdominal and cervical spine injuries. ⋯ Surgical repair of the trachea was uneventful. The diagnosis and airway management of tracheal rupture are discussed. This case illustrates the importance of a full diagnostic examination during invasive anaesthetic procedures such as tracheal intubation.

Case Reports
The use of an endotracheal ventilation catheter for jet ventilation during a difficult intubation.
This case report describes the use of an endotracheal ventilation catheter (ETVC) to provide prolonged intraoperative jet ventilation, reintubation and the maintenance of tracheal access following extubation. It emphasizes that excellent oxygenation and ventilation can be achieved but such management can be complicated by a pneumothorax even when the risks are minimized. A 43-yr-old man presented for possible pulmonary sleeve resection. ⋯ A pneumothorax was noted on the postoperative chest x-ray. This case illustrates prolonged intraoperative jet injection via a "jet stylet" with satisfactory ventilation and oxygenation but complicated by a pneumothorax. Also it illustrates a strategy for the management of a "difficult extubation."
