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)

We report a two-day-old infant who had a period of apnoea lasting six hours following the intravenous administration of succinylcholine (Sch). The results of her plasma cholinesterase level and dibucaine number indicate a congenital absence of plasma cholinesterase (PChE) enzyme, although both parents and siblings had normal cholinesterase levels and dibucaine numbers. This is believed to be the youngest reported case of prolonged apnoea after the administration of succinylcholine.

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.
