Manipulation of hyperbaric lidocaine using a weak magnetic field: a pilot study.
High spinal block is a potentially fatal complication of spinal anesthesia, with an incidence of 0.6 per 1000. Current prevention strategies include decreasing the dose of local anesthetic drug and altering patient positioning such that the location of hyperbaric anesthetic drugs in the neuraxis can be manipulated by gravity. Incorporation of a ferrofluid into a local anesthetic solution, combined with application of an external magnetic field in an in vitro spine model, allowed control of position of a solution of ferrofluid, dye, and local anesthetic against gravity, suggesting an additional mechanism by which anesthesia providers may prevent high spinal block.

Preoperative arterial pulse pressure has no apparent association with perioperative mortality after lower extremity arterial bypass.
Arterial pulse pressure hypertension is associated with perioperative morbidity and mortality in cardiac surgery patients. However, its association with perioperative mortality in other high-risk surgical populations has not been determined. In this study, we tested the hypothesis that increased preoperative arterial pulse pressure is associated with 30-day and 1-year all-cause mortality after lower extremity arterial bypass surgery. ⋯ Our results suggest that increased preoperative arterial pulse pressure might not be associated with all-cause mortality after lower extremity arterial bypass surgery.
