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.

A case is presented of a 33-yr-old parturient with Harrington fusion of her spine who received spinal anaesthesia with 15 mg hyperbaric bupivacaine for Caesarean delivery. Multiple attempts of needle insertion in both midline and paramedian at the L3-4 interspace were unsuccessful, whereas the procedure was performed uneventfully at the midline of the L5S1 interspace. The anatomical considerations and difficulties in achieving reliable epidural anaesthesia after Harrington fusion are reviewed. Spinal anaesthesia performed at the L5S1 interspace may provide less technical difficulty and a more reliable result in such patients.

The role of anaesthetists in providing local anaesthesia for intraocular surgery has changed over the past decade. No longer confined to the interested few, more and more anaesthetists are involved in monitored care and/or are performing eye block anaesthesia. This review summarizes the information related to eye block anaesthesia. ⋯ Complications such as retrobulbar haemorrhage, globe penetration/perforation, visual impairment, brainstem anaesthesia, muscle injury, and oculocardiac reflex are explored. The implications of anticoagulant therapy are examined. The choice between retrobulbar and peribulbar blocks and the role of anaesthetists are discussed.

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)
