A "last ditch" airway.

In a patient whose airway is in jeopardy after unsuccessful attempts at conservative measures to clear it and after failed attempts at intubation, the intravenous tubing connector spike may be considered as an emergency percutaneous tracheostomy device. It is readily available wherever physicians have intravenous solutions at hand. It is inserted through the cricothyroid space with the help of a scalpel blade or other sharp instrument such as a pair of scissors. A severed spike can be as easily carried in a pocket, purse or medical bag as can an intravenous cannula. A number 11 scalpel blade fits neatly between two credit cards. The shape of the spike makes it fortuitously adaptable to intermittent positive pressure ventilation by mouth or standard resuscitation equipment. If the patient is otherwise well enough, it is of sufficient bore to allow spontaneous respiration. I have been fortunate not to have had the opportunity to use this device in an emergency situation as of the time of the submission of this paper.

Plasmapheresis in Crohn's disease.

6 patients with Crohn's disease for 1-14 years have been treated with plasmapheresis for periods of up to 6 months. The symptoms of the one newly diagnosed patient were controlled by plasmapheresis alone, and 5 steroid-dependent patients were able to reduce their steroid requirements. During the study period, 13 clinical relapses were managed without increasing steroid dosage. There was evidence of circulating soluble immune complexes in all the patients and these levels were lowered by plasmapheresis. A possible role of plasmapheresis in the management of Crohn's disease is discussed.

Upper gastrointestinal endoscopy--a GP service.

Since 1974 there has been an open endoscopy service available to general practitioners in the Bournemouth and Christchurch area. Patients are referred directly with a standard form. A retrospective comparison of requests for barium-meal examinations and for endoscopy by general practitioners showed that the reasons for referral were similar. Forty per cent of patients in each group showed no abnormality. Ulceration was found in 21.1% of patients who underwent endoscopy and 9.7% investigated by barium meal. Duodenitis or gastric erosions were found in a further 16% of endoscopies. More hiatus hernias and deformed duodenal caps were found at barium meal. Despite these differences the results of follow-up were similar.
