Does intravenous dihydroergotamine restore arterial pressure during spinal anaesthesia in healthy males?
Does intravenous dihydroergotamine restore arterial pressure during spinal anaesthesia in healthy males?
Intravenous dihydroergotamine restores arterial pressure during spinal anaesthesia primarily through effects on resistance and capacity vessels, without significantly altering cardiac output.
No takes yet. Share an insight, caveat, or question.
May support DHE for spinal anesthesia hypotension without output changes; leaves open safety and efficacy in broader populations.
Bergenwald et al. (1972) studied this question.
