The purpose of this study is to compare two opioid protocols ("H2O" and "1+1") for the treatment of acute severe pain in the emergency department. The investigators primary hypothesis is that the "H2O" protocol will be more efficacious than the "1+1" protocol in Emergency Department patients aged 21-64 years. The primary outcome is the proportion of patients in each arm who choose to forgo additional pain medication at 60 minutes.

1 mg IV hydromorphone followed by an additional 1 mg IV hydromorphone 15 minutes later if the patient answers "yes" to the following question: "Do you want more pain medication?"
1mg I hydromorphone followed by an optional 1 mg IV hydromorphone 15 minutes later if the patient answers "yes" to the question, "Do you want more pain medication?"
|Ages Eligible for Study:
||21 Years to 65 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Age greater than 21 years and less than 65 years: This is a study of non-elderly adult patients. In addition, patients aged 21 years and younger are automatically triaged to the Children's ED.
- Pain with onset within 7 days: Pain within seven days is the definition of acute pain that has been used in ED literature.
- ED attending physician's judgment that patient's pain warrants IV opioids
- Use of other opioids or tramadol within past 24 hours: to avoid introducing assembly bias related to recent opioid use, since this may affect baseline levels of pain and need for analgesics.
- Prior adverse reaction to opioids.
- Chronic pain syndrome: frequently recurrent or daily pain for at least 3 months results in modulation of pain perception which is thought to be due to down-regulation of pain receptors. Examples of chronic pain syndromes include sickle cell anemia, osteoarthritis, fibromyalgia, and peripheral neuropathies.
- Alcohol intoxication: the presence of alcohol intoxication as judged by the treating physician may alter pain perception.
- SBP <90 mm Hg: Opioids can produce peripheral vasodilation that may result in orthostatic hypotension.
- Oxygen saturation < 95% on room air: For this study, oxygen saturation must be 95% or above on room air in order to be enrolled.
- Use of MAO inhibitors in past 30 days: MAO inhibitors have been reported to intensify the effects of at least one opioid drug causing anxiety, confusion and significant respiratory depression or coma.
C02 measurement greater than 46: In accordance with standard protocol, three subsets of patients will have their CO2 measured using a handheld capnometer prior to enrollment in the study. If the CO2 measurement is greater than 46 then the patient will be excluded from the study. The 3 subsets are as follows:
- All patients who have a history of COPD
- All patients who report a history of asthma together with greater than a 20 pack-year smoking history
- All patients reporting less than a 20 pack-year smoking history who are having an asthma exacerbation
