Attitudes of anaesthetists of various grades working in different types of hospital in England and Wales, to parental presence in the anaesthetic room during induction of anaesthesia in children were assessed by means of a postal questionnaire. Of the 300 questionnaires sent out, 244 (82%) were completed. ⋯ A small but significant number expressed reservations about some aspects of parental presence. The grade of anaesthetist and type of hospital did not appear to influence the response.

Comparative StudyComparison of functional endoscopic sinus surgery under local and general anesthesia.
We present a retrospective comparison of intravenous sedation and general anesthesia techniques employed at New York University-Bellevue Medical Center for functional endoscopic sinus surgery. Some authors have stressed the use of local anesthesia with intravenous sedation in order to avoid complications and reduce blood loss. We have reviewed 232 patients who underwent 401 consecutive ethmoidectomies and maxillary antrostomies. ⋯ The rate of operative complications for local anesthesia was 8.7% per patient, with a 1.6% rate of major complications per side. General anesthesia carried an overall complication rate of 2.4% per patient, with no major complications. General anesthesia is a relatively safe and viable option for endoscopic sinus surgery that in selected cases may be preferable to local anesthesia.

Serum inorganic fluoride concentrations and their urinary excretion were examined during and after sevoflurane, isoflurane, or enflurane anesthesia in man. Duration of anesthesia was 3 hours in sevoflurane and enflurane groups (S3 group: n = 10, E3 group: n = 5), and 3 or 5 hours in isoflurane groups (I3 group: n = 5, I5 group: n = 5). Serum inorganic fluoride concentration of the S3 and E3 groups increased immediately following induction, and reached the maximum concentration of 21.8 +/- 9.3 (M +/- SD) mumol.l-1 (S3), 13.6 +/- 6.2 mumol.l-1 (E3) at 1 hour after anesthesia. ⋯ The change of serum inorganic fluoride sharply contrasted with urinary excretion. Our results suggest that fluoride excretion is largely carried out by the kidney. Therefore sevoflurane or enflurane anesthesia should be avoided in patients with renal dysfunction.
