The effect of lidocaine on the pain induced by the intravenous infusion of potassium chloride (KCl) was evaluated. Six volunteer subjects received 10 mEq of KCl in 50 ml of 5% dextrose in water in one arm, and in the other arm received the same solution with 10 mg of lidocaine added. Each solution was infused over 1 hour, and the subjects and investigatorwere blinded. Subjects: rated pain on a seven-point scale (1 is mild, 7 is severe). Pain was significantly less severe with the solutions containing lidocaine. Mean values were 3.17 with lidocaine and 6.17 without lidocaine (p<0.01). Lidocaine in a dose of 10 mg added directly to the infusion solution significantly reduced the pain induced by the I.V. bolus infusion of 10 mEq of potassium chloride.
