Cardiotocographic modifications during continuous epidural anaesthesia in labour
Cardiotocographic variations certainly attributable to epidural anaesthesia were studied over the period 1972-1980 on 716 patients in labour. Transitory side-effects due to both direct and indirect action of local anaesthetics appeared in 1.4% of the cases, without, however, subsequently creating any particular foeto-newborn problem. On the basis of the experience acquired, it seems justifiable to affirm that the correct use of continuous epidural block, affected by very small doses of bupivacaine (10-20 mg per administration) is almost risk-free. The only inconvenience therefore that may sometimes arise would only be due to the relevation of a concealed cava occlusion when the maintenance of a left lateral position is not observed.
