Patient Satisfaction With Subdissociative Dose Ketamine Versus Morphine for Emergency Department Pain Control

Study Overview
=================
Brief Summary
-----------------
The proposed research will be a single blinded (patient) randomized controlled prospective trial of adult patients receiving treatment for moderate to severe abdominal pain to test the hypothesis that patient satisfaction with pain control with Ketamine will be comparable to patient satisfaction with pain control using morphine when treating abdominal pain.

Detailed Description
-----------------
Informed consent will be obtained from patients presenting with chief complaint of moderate to severe abdominal pain in the emergency department who do not meet any exclusion criteria and who willingly agree to participate by signing the written consent form. Investigators will assess the patient's opioid tolerance by asking if they have use an opioid medication in the last week, prescription opioid use at home, and/or recreational opioid use. Patients in both groups will fill out the pre-treatment questionnaire, which will include demographic questions (age, sex, race, height, weight, etc.), a 10cm (100mm) VAS for pain, a 10cm (100mm) VAS to measure patient satisfaction, and a Likert Scale to measure patient satisfaction. Post-treatment survey will be given at 30 minutes after administration of medication. The physician will record whether the patient required additional pain medication after the 30 minutes, final emergency department diagnosis, and final emergency department disposition.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Survey Packet 1 Group<br>Patients who receive Packet 1 will be in group 1, or the treatment group. In this packet will be 4 forms: the consent to participate in the study form, a pre-treatment questionnaire (VAS and other demographic information), post-treatment questionnaire (various questions, including demographic questions [age, sex, race, height, weight, etc.], a 10cm (100mm) VAS for pain, a 10cm (100mm) VAS to measure patient satisfaction, and a Likert Scale to measure patient satisfaction), and a form with specific instructions for the physicians to follow that vary depending on whether the instructions are from Packet 1 or Packet 2. The physician will be asked to administer a sub-dissociative dose of ketamine for pain control (0.3 mg/kg IV over 3-5 minutes). | Drug: Ketamine<br>* Blinded study group will receive ketamine for pain control (0.3 mg/kg IV over 3-5 minutes)<br>|
| Survey Packet 2 Group<br>Patients who receive Packet 2 will be in group 2, or the control group. In this packet will be 4 forms: the consent to participate in the study form, a pre-treatment questionnaire (VAS and other demographic information), post-treatment questionnaire (various questions, including demographic questions [age, sex, race, height, weight, etc.], a 10cm (100mm) VAS for pain, a 10cm (100mm) VAS to measure patient satisfaction, and a Likert Scale to measure patient satisfaction), and a form with specific instructions for the physicians to follow that vary depending on whether the instructions are from Packet 1 or Packet 2.The physician will be asked to administer morphine 4 mg IV push over 3-5 minutes for pain control. | Drug: Morphine<br>* Blinded study group will receive morphine 4 mg IV push over 3-5 minutes for pain control<br>|
