Zones of differential sensory block during extradural anaesthesia.
We have measured spinal segmental levels of anaesthesia to light touch (LT), pinprick (PP) and cold temperature discrimination (TE) during 2% lignocaine extradural anaesthesia in 22 patients, to determine if zones of differential sensory block develop during extradural anaesthesia and, if so, the extent to which TE extends beyond PP or LT levels and how age affects differential block. The media...
متن کاملTemporal summation during extradural anaesthesia.
We have investigated in 10 patients the effect of extradural anaesthesia on temporal summation by comparing pain thresholds to single and repeated (five impulses at 2 Hz) electrical stimuli and compared these tests with pinprick and cold stimulation. Bupivacaine 0.5% (20 ml) was injected at L2-3. After extradural anaesthesia the threshold to repeated stimuli was significantly lower than the thr...
متن کاملExtradural, spinal or combined block for obstetric surgical anaesthesia.
Sir,—Dr Carrie, in an otherwise excellent review of regional anaesthesia in operative obstetrics [1], dismisses the practice of warming bupivacaine before extradural injection as being inconvenient and hardly merited because of a reduction of block onset time of only 20%. In this respect, he quotes our study [2] which recorded a reduction of 30 % in onset time. Moreover, we demonstrated a 23% r...
متن کاملSensory testing of spinal anaesthesia for caesarean section: differential block and variability.
BACKGROUND The aim of this study was to determine if sensory block following spinal anaesthesia, measured with a range of devices, corresponded to the hierarchy of nerve fibre size in the area of differential block, and to compare the distribution and variability of recorded measurements. METHODS Women with singleton pregnancies > 36 weeks of gestation undergoing elective caesarean section un...
متن کاملCardiovascular support during combined extradural and general anaesthesia.
We have examined the effect of prophylactic treatment with i.v. fluid 1000 ml, ephedrine 24 mg or methoxamine 4 mg on cardiovascular responses to both extradural and combined extradural and general isoflurane anaesthesia in 45 adult patients undergoing knee arthroplasty. Heart rate (HR) and systemic arterial pressure (AP) were measured using automated oscillotonometry and cardiac output was mea...
