Key result
Lignocaine 1 mg/kg iv significantly decreased the rate of ventricular dysrhythmias during the passage of a Swan-Ganz pulmonary artery catheter.
Why the study?
Does lignocaine 1 mg/kg IV prevent ventricular dysrhythmias during passage of a Swan-Ganz pulmonary artery catheter in adult patients undergoing open-heart surgery?

Does lignocaine 1 mg/kg IV prevent ventricular dysrhythmias during passage of a Swan-Ganz pulmonary artery catheter in adult patients undergoing open-heart surgery?
Administration of IV lignocaine (1 mg/kg) significantly reduces the incidence of ventricular dysrhythmias during the insertion of a Swan-Ganz pulmonary artery catheter.
Lignocaine may reduce ventricular dysrhythmias during catheter passage; hypothesis-generating and should not yet change practice.
A series of seventy-three adult patients undergoing open-heart surgery was studied, in whom a Swan-Ganz pulmonary artery catheter was inserted. The incidence of complications occurring during insertion and use of the catheter was noted, and a controlled trial carried out to determine the efficacy of lignocaine 1 mg/kg iv in preventing ventricular dysrhythmias during passage of the catheter. A significant decrease in dysrhythmia rate was observed. Ways of minimising or preventing other complications are discussed.

T.J.I. SHAW (1979) conducted an RCT in Open-heart surgery (n=73). Lignocaine was evaluated on Ventricular dysrhythmias during passage of the catheter. Lignocaine 1 mg/kg iv significantly decreased the rate of ventricular dysrhythmias during the passage of a Swan-Ganz pulmonary artery catheter.
