Effect of extradural analgesia using bupivacaine and 2-chloroprocaine on intervillous blood flow during normal labour.
The effect of lumbar extradural analgesia on intervillous blood flow (IBF) during labour was studied in 26 healthy parturients using an i.v. bolus injection of xenon-133. There was a 19% decrease (n.s.) in mean IBF in six parturients (non-extradural control group). Mean IBF increased by 37.5% when 0.25% bupivacaine 10 ml was used and by 35.2% when 2% 2-chloroprocaine 10 ml was used (n.s.). When...
متن کاملQuantitative assessment of extradural bupivacaine analgesia.
Bupivacaine (0.5%) 20 ml was administered extradurally to six healthy volunteers. It was found that simultaneous application of 10 needles to the skin could evoke pain when analgesia was obtained to one needle stimulation. In addition, a laser beam was used as a quantitative technique to activate simultaneously many cutaneous nociceptors. For 7 h, thresholds (sensory and pain) and pain-evoked b...
متن کاملBupivacaine toxicity in association with extradural analgesia for caesarean section.
Evidence of central nervous system toxicity was noted in two patients undergoing extradural analgesia for Caesarean section. There was no cardiovascular depression and both patients recovered rapidly. The patients had received total doses of bupivacaine plain solution of 357.5 mg and 356.25 mg, respectively and the relationship of these to the clinical signs of bupivacaine toxicity is discussed.
متن کاملRopivacaine and bupivacaine in obstetric analgesia.
Studies comparing the efficacy of epidural analgesia for labour have been limited by lack of knowledge about the relative potencies of the involved agents, whether alone or in combination. Recently a clinical model to determine the minimum local analgesic concentration has been developed [1]. This study design estimated the minimum local analgesic concentration or median effective concentration...
متن کاملPostoperative analgesia by continuous extradural infusion of bupivacaine and diamorphine.
Three solutions administered by continuous extradural infusion for postoperative analgesia were compared in a randomized, double-blind manner. All patients underwent major abdominal gynaecological surgery and received 0.125% bupivacaine in 0.9% saline, diamorphine in 0.9% saline (0.5 mg in 15 ml) or diamorphine mixed with 0.125% bupivacaine (0.5 mg in 15 ml), at a rate of 15 ml h-1. The bupivac...
