Aluminium phosphide poisoning: haemodynamic observations. 
Haemodynamic measurements were made on 25 patients with aluminium phosphide poisoning.  There was severe hypotension (mean arterial pressure 62.7 +/- 19.3 mmHg) and reduction in cardiac output (2.13 +/- 0.9 lit/min/m2).  However, the systemic vascular resistance was only moderately elevated (2050 +/- 732 dynes/m2).  The right atrial pressure was increased but the pulmonary artery and pulmonary capillary wedge pressures were normal, even in patients with pulmonary oedema.  Thirteen patients (52%) who died had a lower cardiac output (p less than 0.05).  Saline infusion significantly improved haemodynamics in some patients.  Its judicious use early in the course of treatment may be beneficial.
