Recently, there has been renewed interest in corticosteroid therapy for patients with septic shock. The cortisol response to a tetracosactide stimulation test, otherwise known as a short synacthen test, may identify which patients are most likely to benefit from corticosteroid replacement. Controversy over interpretation of the cortisol response and the correct tetracosactide dose remains. ⋯ There was no association between a cortisol rise >/= 250 nmol x l(-1) and haemodynamic improvement after corticosteroids. A postal questionnaire was sent to adult intensive care units in the United Kingdom to assess national practice. Sixty per cent of intensive care units use corticosteroids in septic shock patients, but only 22% use a short synacthen test to guide therapy.

We evaluated the modified Airway Management Device (AMDTM) in 60 spontaneously breathing anaesthetised patients. The insertion and removal of the device was very easy and atraumatic. The airway was secured on the first attempt in 41 patients (70%; 95% CI 57-80%). ⋯ Ten of these patients were male and two were female; the failure rate was 33% (12-31%) among the male patients and 6% (2-22%) among the female patients. The cuff volumes ranged from 4 ml to 80 ml and cuff pressures from 6 cm H2O to 92 cm H2O. Blood was seen on removal in three patients (6%; 2-16%) and nine patients (18%; 10-30%) experienced sore throat after removal of the device.
