The modified nasal trumpet (MNT) is a standard nasopharyngeal airway with an added distal fenestration and fitted with a 15 mm adaptor to permit connection to an anaesthesia circuit. ⋯ The MNT has a place in the operating room suites as a useful airway management device.

Randomized Controlled Trial Comparative Study Clinical Trial
Urinary bladder scanning after day-case arthroscopy under spinal anaesthesia: comparison between lidocaine, ropivacaine, and levobupivacaine.
Micturition problems after spinal anaesthesia may delay hospital discharge. The use of lidocaine has raised concerns because of the occurrence of transient neurological symptoms (TNS). This randomized double-blind study was designed to compare the newer local anaesthetics with lidocaine regarding block characteristics, micturition problems, and discharge times in day-case spinals for arthroscopy. ⋯ Our study suggested that the three local anaesthetics behave similar regarding quality of anaesthesia and motor block but voiding and discharge occurred significantly earlier with lidocaine although the 40 min difference was not impressive considering a spinal discharge time interval of 4-5 h.

Randomized Controlled Trial Comparative Study Clinical Trial
Desflurane compared with propofol for postoperative sedation in the intensive care unit.
We hypothesized that emergence from sedation in postoperative patients in the intensive care unit would be faster and more predictable after sedation with desflurane than with propofol. ⋯ We found shorter and more predictable emergence times and quicker mental recovery after short-term postoperative sedation with desflurane compared with propofol. Desflurane allows precise timing of extubation, shortening the time during which the patient needs very close attention.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of four strategies to reduce the pain associated with intravenous administration of rocuronium.
I.V. rocuronium produces intense discomfort at the site of injection in conscious patients. Four strategies to reduce or prevent this discomfort were studied. ⋯ Sodium bicarbonate 8.4%, when added to rocuronium, markedly reduces the experience of pain during the i.v. administration of a small dose of rocuronium.

Formal studies on stress in anaesthetists have usually measured stress through mental or physiological indicators. When using this approach, one must be careful not to confuse the effects of stress or outcome variables and the sources of stress or antecedent variables. To date, it seems from the literature that there is no clear evidence of a common pattern of physiological effects of stress for all the sources of stress. Furthermore, work characteristics such as job satisfaction, job control and job support may moderate the effects of stress. ⋯ Remedial actions are discussed at the end of the paper.
