Brief summary

This is a retrospective chart review to determine the non-inferiority of performing lower extremity peripheral nerve block placement under spinal anesthesia compared to its pre-spinal counterpart.

Detailed description

Primary outcome: \- The investiigators will be looking into persistent abnormal neuropathic symptoms lasting more than 7 days following a sciatic popliteal nerve block.

Design outcomes

Primary

Measure	Time frame	Description
Persistent Abnormal Neuropathic Symptoms	lasting more than 7 days following a sciatic popliteal nerve block	Definition of abnormal neuropathic symptoms including numbness, tingling, burning, or pain sensation.

Secondary

Measure	Time frame	Description
NRS pain scores in recovery	PACU recovery stay (up to 48 hours)	A score on a scale from 0 to 10 on how bad the pain is. 0 means no pain, 10 means worst pain. A lower score means a better outcome.
Amount of supplemental analgesic and antiemetic provided in the PACU	PACU recovery stay (up to 48 hours)	This includes: IV dilaudid push, oral oxycodone, tramadol, hydrocodone, dilaudid, acetaminophen, ketorolac, ondansetron, dexamethasone.
Anesthesia induction time	From the time which patients enter the OR to time of anesthesia induction end (up to 24 hours)	time from entering the OR to time of anesthesia induction end as defined by the completion of both the spinal and sciatic nerve blockade
Number of hypoxemia events during induction time	during induction time (up to 24 hours)	—
Amount of sedation given	during induction time (up to 24 hours)	fentanyl, ketamine, midazolam, propofol
