Brief summary
We are testing whether patients who received protocolized pain management (1 mg of IV hydromorphone followed by an additional 1 mg Intravenous (IV) hydromorphone 15 minutes later if the patients wants more) will have better pain relief and no more adverse events than patients receiving discretionary care, in which the patients receives whatever IV opioid the treating physician wants to give, in whatever dose.
Interventions
1 mg IV hydromorphone followed by an optional 1mg IV hydromorphone 15 minutes later
Any IV opioid in the dose chosen by the treating physician. May include hydromorphone as well.

Eligibility
Inclusion criteria
1. Age 21 to 64 years. 2. Pain with onset within 7 days. 3. Emergency Department attending physician's judgment that patient's pain warrants use of intravenous opioids. 4. Normal mental status.
Exclusion criteria
1. Prior use of methadone. 2. Use of other opioids, tramadol, or heroin in the past seven days. 3. Prior adverse reaction to morphine, hydromorphone, or other opioids. 4. Chronic pain syndrome. 5. Alcohol intoxication. 6. Systolic Blood Pressure \< 90 mm Hg. 7. Use of monoamine oxidase (MAO) inhibitors in past 30 days. 8. Weight less than 100 pounds. 9. Baseline room air oxygen saturation less than 95%. 10. C02 measurement greater than 46: In accordance with a number of similar studies that we have performed, four 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 4 subsets are as follows: 1. All patients who have a history of chronic obstructive pulmonary disease (COPD) 2. All patients who have a history of sleep apnea 3. All patients who report a history of asthma together with greater than a 20 pack-year smoking history 4. All patients reporting less than a 20 pack-year smoking history who are having an asthma exacerbation

Outcome results
Percentage of Patients With Successful Treatment
Successful treatment was defined as either declining additional pain medication when asked at 15 minutes or accepting additional pain medication at 15 minutes but then declining additional pain medication at 60 minutes
Time frame: 60 minutes
Population: The discrepancy between the number of patients enrolled and randomized and the number of patients included in analysis is due to missing data (6 from Protocolized and 4 from Discretionary Care) and participants enrolled more than once (2 from Protocolized).
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Protocolized | Percentage of Patients With Successful Treatment | 86.8 Percentage of Participants |
| Discretionary Care | Percentage of Patients With Successful Treatment | 76.6 Percentage of Participants |
Changes in Pain Intensity From Baseline to Other Pain Assessment Times (15 and 60 Minutes).
Mean change in pain intensity between baseline and 15 minutes and between baseline and 60 minutes post treatment. Pain intensity is measured on a numerical rating scale (NRS) from 0 (no pain) to 10 (worst pain imaginable). The averages were calculated by finding the mean of change in pain intensity for each patient.
Time frame: Up to 60 minutes
