The minimum alveolar concentration (MAC) of an inhaled anaesthetic describes its potency as a general anaesthetic. Individuals vary in their sensitivity to anaesthetics and we sought to determine whether an individual animal's sensitivity to inhaled anaesthetics would be maintained across different agents. ⋯ These findings show that an individual has a consistent degree of sensitivity to a variety of inhaled anaesthetics, suggesting a genetic basis for sensitivity to inhaled anaesthetic effects.

Poor positioning of an endobronchial double lumen tube (DLT) could affect oxygenation during one lung ventilation (OLV). We set out to relate DLT position to hypoxaemia and DLT misplacement during OLV. ⋯ Patients who have DLT malposition after placing the patient in the lateral position had more DLT malposition during OLV and hypoxaemia during OLV.

We report a case of acute upper airway obstruction caused by a rapidly expanding blood-filled bulla in the oropharynx (angina bullosa haemorrhagica), requiring tracheal intubation. The larynx could not be visualized by either awake fibreoptic laryngoscopy or direct laryngoscopy under anaesthesia. Surgical tracheostomy was therefore performed under general anaesthesia.

Little attention has been paid to pain on medical wards, with publications limited to the management of surgical patients. We wanted to establish the prevalence and severity of pain in the general medical setting, and how this compared with other clinical specialties. ⋯ Patients in all hospital specialities experience pain. Until the issue of pain management in medical patients is fully addressed the situation will not improve.
