Extradural analgesia: the influence of volume and concentration of bupivacaine on the mode of delivery, analgesic efficacy and motor block.
Five hundred and seventeen women in labour receiving extradural analgesia, using bupivacaine plain solution, were randomly allocated to one of three groups. Group A received 6-8ml of 0.5% solution, group B 10-14ml of 0.25% solution, and group C 6-8 ml of 0.25% solution. Spontaneous delivery occurred in 31.7% of patients in group A, 38.7% in group B and 53% in group C (P less than 0.001). The pe...
متن کاملSafety and efficacy of a low volume extradural test dose of bupivacaine in labour.
A low volume of bupivacaine has been recommended as a "test dose" before extradural injection of local anaesthetic in labour. In order to test the safety and efficacy of this test procedure, the effects of bupivacaine 1.6 ml given by extradural injection were compared with those following the same dose given by the intrathecal route. Various indices of motor, sensory and autonomic block were re...
متن کاملComparison of carbonated bupivacaine and bupivacaine hydrochloride for extradural anaesthesia.
A double-blind comparison of carbonated bupivacaine and bupivacaine hydrochloride in extradural anaesthesia was performed in 40 patients. No significant differences in the onset times, sensory blockade, motor blockade and duration of anaesthesia were demonstrated. Carbonated bupivacaine does not appear to offer any advantage over the hydrochloride salt for extradural anaesthesia.
متن کاملEffects of concentration of local anaesthetic drugs in extradural block.
An increase in the concentration of bupivacaine from 0.5% to 0.75% and etidocaine from 1.0% to 1.5% for extradural block resulted in a more rapid onset of sensory analgesia and motor blockade, a greater frequency of adequate analgesia,a greater depth of motor block and a longer duration of sensory analgesia and motor blockade. An increase in the concentration of prilocaine from 2% to 3% failed ...
متن کاملPatient-controlled extradural analgesia to compare bupivacaine, fentanyl and bupivacaine with fentanyl in the treatment of postoperative pain.
We have assessed the effect of combining extradural bupivacaine and fentanyl in 60 orthopaedic patients who received 0.125% bupivacaine (bupivacaine group), fentanyl 5 micrograms ml-1 (fentanyl group), or 0.125% bupivacaine combined with fentanyl 5 micrograms ml-1 (combined group), delivered by patient-controlled extradural analgesia for 24 h via a lumbar extradural catheter. Adding bupivacaine...
