We describe a patient at 20-22 weeks gestation, with a known difficult airway, who underwent eight sessions of electroconvulsive therapy using the ProSeal laryngeal mask airway and controlled ventilation. The airway management options for brief periods of general anaesthesia in patients with increased gastric volume are discussed.

Heart block and arrhythmia are complications of pulmonary artery and cardiac catheterization. Injury to the conducting system of the heart often involves the right bundle causing right bundle branch block (RBBB). If patients already have left bundle branch block (LBBB), complete heart block (CHB) may result. ⋯ The function of the AV node and bundle of His in these patients has not been studied before. We report a patient with LBBB who developed CHB during insertion of a central venous cannula. Conduction through the AV node and His-Purkinje system was intact, showing that the transient RBBB was caused by traumatic injury rather than by other disease of the conduction system.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the effects of intrathecal ropivacaine, levobupivacaine, and bupivacaine for Caesarean section.
Intrathecal ropivacaine is roughly dose equivalent to bupivacaine at a ratio of 1.5:1 ropivacaine:bupivacaine.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Patient well-being after general anaesthesia: a prospective, randomized, controlled multi-centre trial comparing intravenous and inhalation anaesthesia.
The aim of this study was to assess postoperative patient well-being after total i.v. anaesthesia compared with inhalation anaesthesia by means of validated psychometric tests. ⋯ Total i.v. anaesthesia improves early postoperative patient well-being and reduces the incidence of PONV.

Randomized Controlled Trial Comparative Study Clinical Trial
Epidural versus intrathecal morphine for postoperative analgesia after Caesarean section.
Perispinal anaesthesia for Caesarean section allows injection of epidural (ED) or intrathecal (i.t.) morphine to provide long-lasting postoperative analgesia. To compare these two routes, a prospective, randomized, double-blinded study of 53 patients undergoing elective Caesarean section was performed. ⋯ The ED protocol was more effective than the i.t. protocol, whilst side-effects were similar.
