An estimate for the calculation of continuous rate infusion for
lignocaine (25-75 ug/kg/min). The figure given is the approximate rate of delivery of
the drugs diluted in fluids (ml/mm) with the drops per mm in parentheses (assuming
20 drops 1 ml)) if 25 ml of 2% lignocaine without adrenaline (21 mg/ml) is added to
500m1 of fluids (see Appendix B).
