The effect of ketamine alone and in combination with N2O (70% inspired) on median nerve somatosensory evoked potentials (SSEPs) was investigated in 16 neurologically normal patients undergoing elective abdominopelvic procedures. The anesthetic regimen consisted of ketamine (2 mg/kg iv bolus followed by continuous infusion at a rate of 30(More)
Although the effect of systemic opioids on somatosensory evoked potentials has been well described, little is known about the interaction between intrathecally administered opioid analgesics and somatosensory evoked potentials. Accordingly, the influence of intrathecally administered morphine on posterior tibial nerve somatosensory cortical evoked(More)
The effect of a high epidural block on the catecholamine response to hypoventilation was studied in six unanesthetized dogs given intravenous sufentanil (15 micrograms.kg-1). Sufentanil alone resulted in a increase of norepinephrine (NE) concentration from 108 +/- 73 pg.ml-1 to 843 +/- 399 pg.ml-1 and epinephrine (E) from 279 +/- 80 pg.ml-1 to 2010 +/- 1416(More)
Dural puncture during lumbar sympathetic block (LSB) is a recognized but apparently uncommon complication. Interestingly, post dural puncture headache (PDPH) has not been reported as a complication of LSB. The authors report two cases of PDPH after LSB. In the first case an attempt to treat the PDPH with an epidural blood patch failed. In the second case(More)
