The ethics of general practice and advertising.
UK general practitioners (GPs) are self-employed entrepreneurs running small businesses with commercial considerations. In this situation there is no clear distinction between information, self-promotion and advertising. In response to the growing public demand for more information about medical services, the medical profession should voluntarily accept the notion of soft self-promotion in the form of 'notices' or 'announcements' placed in newspapers. Newspapers are the most effective way of giving easy access to information. The resistance to newspapers may be more concerned with preserving certain medical traditions than consideration of the public interest. The General Medical Council's (GMC's) arguments against soft self-promotion are seen as misguided paternalism, inconsistent and irrational.

Use of i.m. ranitidine for the prophylaxis of aspiration pneumonitis in obstetrics.
Twenty patients who underwent elective Caesarean section received ranitidine 150 mg by mouth 8-14 h, and 50 mg i.m. 90 min, before surgery. Intraoperative gastric aspiration resulted in contents with a pH greater than 2.5 and volume less than 25 ml in all patients (mean pH 6.5 (SD 0.8); mean volume 9.0 (SD 7.2) ml). Sixty patients in labour, who received ranitidine 50 mg i.m. 6-hourly, underwent emergency surgery. Half of this group received, in addition, a single preinduction dose of either 15 or 30 ml of sodium citrate 0.3 mol litre-1. A further 30 patients who remained unmedicated during labour and required emergency surgery received a preinduction dose of 15 or 30 ml of sodium citrate 0.3 mol litre-1 alone. Ranitidine medication resulted in a mean aspirated gastric volume of 31.4 (26.6) ml and pH of 5.3 (2.1); five of 30 patients had a pH less than 2.5. The addition of sodium citrate 0.3 mol litre-1 resulted in gastric pH greater than 2.5 in all patients and a mean gastric volume of 43.2 (38.3) ml. The group who received only sodium citrate 0.3 mol litre-1 had a mean pH of 5.3 (1.1) and a mean volume 122.7 (98.2) ml.
