Why the study?
Spinal anesthesia commonly causes central hemodynamic disturbances such as hypotension, which may be prevented by unilateral anesthesia.
Does unilateral spinal anesthesia reduce hemodynamic disturbances compared to bilateral spinal anesthesia?
Does unilateral spinal anesthesia reduce hemodynamic disturbances compared to bilateral spinal anesthesia?
Unilateral spinal anesthesia allows for lower anesthetic doses, resulting in more stable hemodynamics and fewer hypotensive episodes compared to bilateral or general anesthesia.
No takes yet. Share an insight, caveat, or question.
May support unilateral spinal anesthesia to limit hypotension; leaves open need for randomized confirmation before practice change.
