Plasma Glucose Levels With Dexamethasone as Adjuvant to Interscalene Block

Summary

The purpose of this study is to determine the Finger Blood Glucose (sugar) when dexamethasone is added to a local anesthetic for a shoulder nerve block procedure. The investigators hypothesize that there is no increase in plasma glucose when 8 mg of dexamethasone is used as an adjuvant with local anesthetic to interscalene regional anesthesia. By performing finger stick blood glucose measures pre/peri and post operatively the investigators will be able to determine if any such increase exists.
