Safety of local anesthesia combined with monitored intravenous sedation for American Society of Anesthesiologists 3 and 4 patients undergoing lower limb-preservation procedures.
The aim of this retrospective study is to evaluate the prognostic value of American Society of Anesthesiologists (ASA) classification with regard to perioperative variables of cardiac complications, pulmonary complications, and mortality in patients undergoing limb salvage procedures with monitored intravenous sedation and foot and ankle blocks. None of the ASA 3 or 4 patients experienced any pulmonary or cardiac complication; no patient required invasive monitoring or postoperative cardiac care unit admission. We suggest that the performance of peripheral foot and ankle blocks with monitored intravenous sedation appears to be a safe and useful option for ASA 3 and 4 patients undergoing limb-preservation surgery.
