Brief Summary:

This research project is geared towards geriatric analgesia in the Emergency Department (ED) with a goal of reducing the administration of opioid pain medications to elderly patients, thereby avoiding the commonly occurring, severe side effects associated with such medications, including hypotension, respiratory depression, altered mental status, delirium, as well as nausea/vomiting and constipation.

The primary outcome of the study will be difference in pain score from baseline to 30 minutes post-medication administration. The secondary outcomes will be the need for rescue analgesia and the incidence of adverse side effects and patients' satisfaction with low-dose ketamine or low dose morphine analgesia in managing their painful conditions in the ED.

This project has the potential to change and modify the ED approach to geriatric analgesia by virtue of minimizing the use of opioid administration in elderly patients. T

Arm Intervention/treatment
Active Comparator: Morphine Group
intravenous Morphine given at 0.1 mg/kg as intravenous infusion (10 min) with a maximum dose of 10 mg.
Drug: Morphine
intravenous Morphine given at 0.1 mg/kg as intravenous infusion (10 min) with a maximum dose of 10 mg. The device is the Care Fusion Alaris PC.

Experimental: Ketamine Group
Ketamine administered in sub-dissociative doses 0.3 mg/kg as a intravenous infusion (10 min)
Drug: Ketamine
Ketamine administered in sub-dissociative doses 0.3 mg/kg as a intravenous infusion (10 min). The device is the Care Fusion Alaris PC.

Primary Outcome Measures :
  1. Pain Score at 30 minutes [ Time Frame: 30 minutes ]
    The primary outcome will be the comparative reduction of NRS pain scores between the 2 groups at 30 minutes.
