High Utilization of Neuraxial Anesthesia in Revision Total Joint Arthroplasty is Safe and Effective.

For rTHA, general anesthesia was associated with a longer length of stay (83.0 versus 47.4 hours, P < 0.001), increased blood loss (610.0 versus 406.8 mL, P = 0.007), higher rates of transfusion (28.6 versus 11.4%, P = 0.02), and higher readmissions (18.6 versus 1.4%, P = 0.002).

Total (144.9 versus 79.5 P < 0.001), intraoperative (59.8 versus 25.4, P < 0.001), and postoperative (85.0 versus 54.0, P = 0.002) morphine equivalents administered were higher in the THA general anesthesia group than the neuraxial anesthesia group.
