- The informed consent process will be initiated by investigators in the emergency department.
- All potential subjects will be informed that participation in the study could lead to a positive urine drug test that could remain positive for up to a month after the conclusion of the study.
- Female subjects of child bearing age, will have a pregnancy test performed prior to enrollment; any subjects who are pregnant will be excluded from this project.
- Each subject will be asked to grade his/her pain severity on a 100mm non-hatched visual analog scale (VAS) ranging from 0 (no pain) to 100 (worst, maximum pain).
- Each subject will be asked to fill out a baseline pain questionnaire
- Each subject will be placed on monitors for continuous pulse oximetry, Heart Rate, Respiratory Rate, and blood pressure every 5 minutes for the duration of the study of one hour and longer for any patient who needs continued care. The patients temperature will be taken prior to the start of the protocol.
- Each subject will have an intravenous catheter placed.
- Each subject will be sequentially assigned to one of three treatment groups, based on a computer-generated randomization schedule, to receive an intravenous infusion of sub-dissociative Ketamine (0.25mg/kg), sub-dissociative dose Ketamine (0.5mg/kg), or an equal amount of normal saline.
- All medications will be prepared by an emergency department pharmacist and all study medication intravenous bags will be identical in appearance and will be administered by the emergency department nurse caring for the patient who will be blinded to the study drug.
- Each subject will receive lightly tinted sunglasses to wear during the duration of the study to minimize bias as ketamine can evoke a tell-tale short- lived nystagmus
- Each subject will receive the study medication over a 20 minute period via an automated pump. At this point, the subjects will be asked to rate their pain on a VAS and asked if they need additional pain medication that will consist of intravenous hydromorphone with the dose and frequency determined by the discretion of the treating physician and documented on the data collection sheet.

Other Name: Normal Saline
Experimental: very low dose ketamine
0.25 mg/kg of sub-dissociative ketamine as an experimental arm

- Compare pain relief between the 3 treatment groups as measured by the VAS. A decrease of at least 20mm on the VAS will be considered "significant" pain relief [ Time Frame: 1 hour ]Subjects pain will be assessed by VAS at 20, 40 and 60 minutes. Differences at 60 minutes will be compared for the primary outcome
- Compare total dosage of IV hydromorphone needed as rescue therapy to achieved adequate pain relief [ Time Frame: 1 hour ]Compare need for rescue therapy at the completion of the 1 hour study
- Assess the risk for complications of sub-dissociative dose ketamine [ Time Frame: 1 hour ]Subjects will be continuously assessed for complications secondary to the sub-dissociative ketamine
