Management of the cardiovascular manifestations of poisoning by the Indian red scorpion (Mesobuthus tamulus).
The efficacy of nifedipine and prazosin in combination or alone in the management of cardiovascular manifestations caused to Mesobuthus tamulus poisoning was investigated. ⋯ Nifedipine alone did not prevent myocardial damage unless the peripheral action of venom was blocked by prazosin.

Comparative StudyTransoesophageal Doppler echocardiographic measurement of cardiac output by the mitral annulus method.
To compare cardiac output measured by the transoesophageal Doppler and thermodilution techniques. ⋯ After cardiac output had been measured simultaneously by both the Doppler and thermodilution techniques, subsequent transoesophageal Doppler alone gave a clinically useful measurement of cardiac output.

To evaluate outcome in patients managed outside an intensive care unit after open heart surgery. ⋯ This study confirms that over 90% of patients undergoing cardiac surgery would recover safely and be treated effectively in a more economical area than intensive care.

Case ReportsFailure of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis.
Carcinoid heart disease typically results in pulmonary stenosis and tricuspid incompetence. Percutaneous balloon dilatation is an effective treatment for congenital pulmonary stenosis and has been applied successfully to tricuspid stenosis caused by carcinoid heart disease. The value of balloon dilatation of the pulmonary valve in carcinoid pulmonary stenosis was assessed. ⋯ Though balloon dilatation of the pulmonary valve is technically feasible it is unlikely to provide useful palliation in carcinoid heart disease. Valve surgery should be considered in patients in whom the malignancy is controlled but carcinoid heart disease is producing drug resistant congestive heart failure.

Negative extrathoracic pressure ventilation for phrenic nerve palsy after paediatric cardiac surgery.
To investigate the feasibility of negative extrathoracic pressure ventilation as a respiratory support following phrenic nerve palsy after cardiac surgery. ⋯ Negative pressure ventilation may be an alternative to positive airway pressure ventilation in the management of phrenic nerve palsy. A multicentre randomised controlled trial is now required to assess further the role of negative pressure ventilation in phrenic nerve palsy.
