The best view at laryngoscopy using the McCoy laryngoscope with and without cricoid pressure.
The best view obtained by levering the tip of the McCoy laryngoscope blade with or without modified cricoid pressure was studied in 100 patients presenting for general surgery. The airway was assessed pre-operatively (Mallampati score, thyromental distance, mouth opening, protrusion of the jaw and weight) in an attempt to identify the patients who might benefit from the use of the McCoy laryngoscope. The vocal cords were visible at laryngoscopy with the blade in the neutral position in 32 cases. ⋯ The epiglottis only was seen in 18 patients and in two not even the epiglottis could be visualised. Elevation of the blade or modified cricoid pressure improved the view in 38/68 cases and 57/68 cases, respectively (p < 0.001, Wilcoxon signed rank). Using our method of pre-operative assessment we were unable to identify those patients who might benefit from either manipulation.

This article reports the results of a survey of acupuncture practice in chronic pain clinics in the United Kingdom. The survey reveals that acupuncture is widely used in the treatment of chronic pain with 84% of those responding stating that is was available at their clinics. The majority of practitioners had attended a course at one of the 'acupuncture schools' but in about one fifth of the clinics the practitioner had not received any formal training.

We studied the frequency with which treatment was withdrawn in intensive care patients and the primary reason for reaching the decision. The medical records of patients having had active treatment withdrawn between August 1992 and February 1996 inclusive were reviewed. Patients were classified into an imminent death group consisting of those expected to die, a qualitative group who had treatment withdrawn on quality of life considerations and a lethal conditions group who had associated disease that precluded long-term survival. ⋯ The primary reason for treatment withdrawal was imminent death in 45% of patients, qualitative considerations in 50% and lethal conditions in 5%. The reason varied significantly depending on the patient's age. Treatment is withdrawn commonly in ICU, the primary reason being quality of life considerations as often as because death is the expected outcome.
