Summary
Patients scheduled to go home after ankle surgery at HSS typically receive a sciatic nerve
block in the popliteal fossa and oral analgesic tablets (such as Percocet). Popliteal fossa
nerve blockade has reduced pain for these patients (YaDeau et al, Anesth Analg
2008;106:1916-20), but unfortunately the patients still often experience moderate to severe
pain after the block wears off. The investigators wish to study two additives that may
prolong the period of analgesia provided by the nerve block. The additives will be studied in
the context of a standardized postoperative multimodal analgesic pathway.
Primary outcome:
Does adding dexamethasone and / or buprenorphine prolong the analgesia provided by a
popliteal fossa nerve block?
