Many anesthesiologists have called for the abandonment of the epidural test dose in the obstetric patient, citing its lack of sensitivity and specificity. A test dose of lidocaine 1.5% with epinephrine 1:200,000, in combination with aspiration, is highly effective in detecting incorrect placement of an epidural catheter. ⋯ It should not be administered during uterine contraction, as labor pain may trigger a tachycardic response. This test dose has been extensively studied and is safe both for both mother and fetus.
