To randomize patients, consent forms will be pre-labeled with a random subject identification number. This number will serve as the participants' study ID for all data collection in order to maintain privacy and confidentiality. Additionally, this number will be linked to a sealed envelope containing the random treatment group. The study coordinator will create the labels and assemble the envelopes to ensure all investigators remain blind to the treatment groups. This sealed envelope will be given to the anesthesia providers for the amputation. The anesthesia team will then administer the assigned treatment prior to induction of general anesthesia. Half of the patients will be randomized into the treatment group, and half of the patients will be randomized into the control group.
