To determine the publication rate of abstracts as peer-reviewed manuscripts during the five years subsequent to their presentation, the rates of publication of abstracts that were presented at meetings of four anaesthesia societies (American Society of Anesthesiologists (ASA), International Anesthesia Research Society (IARS), Anaesthesia Research Society (ARS) and Canadian Anaesthetists' Society (CAS), in 1985 were determined. Abstracts (total = 215) from each of the four meetings were selected (ASA n = 114/573 total, IARS n = 39/119, ARS n = 33/99 and CAS n = 29/58) and their appearances in the literature as peer-reviewed manuscripts were determined using MEDLINE for the years 1985 to 1990 under the surname of the presenting author. The contents of the abstracts were compared with those of the resultant manuscripts. ⋯ The proportions of abstracts that were published as manuscripts from the four societies were similar. Of the abstracts that were published as manuscripts, 13% from the ASA, 16% from the IARS, 16% from the ARS and 0% from the CAS were published four or five years after abstract presentation. Although the overall proportion of abstracts that was published within five years of presentation did not differ from the rate of publication within three years, we recommend that a uniform policy with respect to the time interval for citation of abstracts be adopted for all anaesthesia journals.

In view of the complications of general, spinal, and caudal anaesthesia for inguinal hernia repair in high-risk neonates, an evaluation of lumbar epidural anaesthesia (LEA) was undertaken to assess its technical feasibility, effectiveness and incidence of complications. In 18 consecutive cases, gestational age 26 +/- 2.6 wk, birth weight 877 +/- 310 g, 16 (89%) had bronchopulmonary dysplasia and 12 (67%) were oxygen-dependent at the time of surgery. Using a standard loss of resistance technique and a 4.0 cm 20 G epidural needle, the epidural space was positively identified on the first attempt in 16 (89%), and on the second attempt in 2 patients (11%). ⋯ Ten infants were analgesic to T2, four to T4, two to T6 and two to T8. Intraoperative periodic breathing was seen in seven infants (39%), four with oxyhaemoglobin desaturation to 75%, and two to 85%. All responded to increased FIO2.(ABSTRACT TRUNCATED AT 250 WORDS)

Blockade of conduction in the saphenous nerve is important in providing surgical anaesthesia in the lower leg. Unfortunately, previously described techniques have lacked clinical effectiveness in practice. We developed a transsartorial approach for conduction block of the saphenous nerve. ⋯ The success rates of the BKFB and FPFB were 65% and 40% respectively. A successful block with the transsartorial approach provided complete anaesthesia of the medial malleolus in 94% of subjects whilst the BKFB and FPFB provided complete anaesthesia of the medial malleolus in less than 40% of the successful blocks. We recommend the transsartorial approach for more effective block of the saphenous nerve.

To remedy the lack of information about the continuing medical education (CME) practices of anaesthetists, we designed a survey to define and compare the CME activities of specialist anaesthetists in community-based and university-affiliated practices: 463 members of the Canadian Anaesthetists' Society in the Province of Ontario (263 community-based and 200 university-affiliated (University of Toronto) anaesthetists). Data from 304 (65.6%) respondents (172 community-based and 132 university-affiliated anaesthetists) were analyzed by non-parametric analysis (statistical significance P < 0.05). Most respondents spent between two to four hours per week on CME activities. ⋯ Formal teaching, including seminars, workshops, and annual society meetings, although the second most commonly used technique to obtain CME, was considered as effective as journal reading. Instructional media techniques were the least commonly used and considered the least effective (P < 0.05). Most community-based and university-affiliated anaesthetists obtained CME by a variety of techniques; of all respondents, 77% have no formal method of assessing their learning needs and 88% would consider participation in a formalized learning needs assessment programme.
