Randomized Controlled Trial Clinical Trial
The use of remifentanil for intubation in paediatric patients during sevoflurane anaesthesia guided by Bispectral Index (BIS) monitoring.
We studied the intubating conditions, haemodynamic and endocrine changes following tracheal intubation during sevoflurane anaesthesia guided by Bispectral Index (BIS) monitoring in 40 children who received either remifentanil 1 microg.kg-1 (group R) or saline 1 ml.kg-1 (group S). Acceptable intubating conditions were found in all patients in group R (n = 20), compared to only 12 patients in group S (p = 0.002). ⋯ There were no side-effects in either group that required intervention. Intubating conditions during sevoflurane anaesthesia in children were found to be improved by a single bolus dose of remifentanil 1 microg.kg-1.

The prevalence of latex allergy has increased since the 1980s. As latex is found throughout hospitals and operating theatres, careful planning is required for latex-allergic patients who present pre-operatively. We conducted a postal survey of 269 departments of anaesthesia in England and Wales; responses were received from 208 (77%). ⋯ Many respondents called for national guidelines. We are reassured that the majority of trusts have an up-to-date latex allergy protocol and latex-free equipment store. However, relatively few have nominated members of staff responsible for these and peri-operative care of susceptible patients.

The purpose of this investigation was the description of structure and process quality based on the analysis of 1612 fibreoptic intubations. We evaluated all fibreoptic intubations (nasotracheal in awake patients and orotracheal in anaesthetised patients) from a previously described database over a period of 2 years. We assessed structure quality by evaluating the distribution of the fibreoptic intubations across all staff anaesthetists, and process quality by analysing the number of attempts, the time required, the cases where we had to switch to conventional intubation and the complications. ⋯ Within 3 min, 93.9% of all fibreoptic intubations were successfully completed. In 24 cases, fibreoptic intubation was abandoned. Severe nasal bleeding as a major complication occurred in 1.3% of the nasotracheal intubations.

A timesheet questionnaire was used to assess the time it took from informing the anaesthetist about a case to the start of operative delivery in 78 consecutive patients undergoing caesarean section. Median (IQR [range]) times for grade-1 cases (immediate threat to the life of the mother or fetus) and grade-2 cases (fetal or maternal compromise without immediate threat to life) were 20 (17-35 [6-75]) min and 41 (27-60 [17-136]) min, respectively. ⋯ Many significant delays were apparently not perceived by the anaesthetist. In nine (69%) grade-1 cases, the 30-min target decreed by the Association of Anaesthetists of Great Britain & Ireland and the Obstetric Anaesthetists' Association was achieved.
