简要总结
Introduction: Ketamine has been well studied for its efficacy as an analgesic agent. However, intranasal (IN) administration of ketamine has only recently been studied in the emergency setting.
Objective: To elucidate the efficacy and adverse effects of a sub-dissociative dose of IN Ketamine compared to IV and IM morphine.
Methods: A single-center, randomized, prospective, parallel clinical trial of efficacy and safety of IN ketamine compared to IV and IM morphine for analgesia in the emergency department (ED). A convenience sample of 90 patients aged 18-70 experiencing moderate-severe acute traumatic pain (≥80mm on 100mm Visual Analog Scale [VAS]) were randomized to receive either 1.0mg/kg IN ketamine, 0.1mg/kg IV MO or 0.15mg/kg IM MO. Pain relief and adverse effects were recorded for 1 hour post-administration.
Primary Outcomes: The primary outcome was efficacy of IN ketamine compared to IV and IM MO, measured by "time-to-onset" (defined as a ≥15mm pain decrease on VAS), as well as time to and degree of maximal pain reduction.

入选标准
- •Patients aged 18-70 years, with mild to moderate blunt trauma (sustained in road, workplace and home accidents) causing moderate to severe pain (≥ 80mm score on a 100mm Visual Analog Scale=VAS) were eligible for participation in the study. Inclusion criteria also included a Glasgow Coma Score (GCS) of 15, body weight of 50-110 kg, systolic blood pressure of 90-160 mmHg, heart rate <100 bpm. Patients were also required to have an American Society of Anesthesiologists (ASA) score of 1 or 2, deny head injury, and deny regular use or use of opiates.
排除标准
- •Any analgesia received within the prior 3 hours, allergic sensitivity to morphine or ketamine, a large meal ingested within the previous hour, pregnancy, deviated nasal septum or trauma to the nose, and a history of a psychiatric condition. Despite evidence that ketamine does not exacerbate intracranial hemorrhage in patients with head trauma, patients with head injury complaining of loss of consciousness, dizziness, vomiting, or nausea were excluded as well.

结局指标
主要结局
Effectiveness of intranasal ketamine in decreasing pain intensity [patient assessed - VAS pain score]
时间窗: 1 hour post administration
Time to achieve a clinically meaningful pain reduction was defined as the first time-point at which the patient reported 15mm of pain reduction or more. Maximal pain reduction was defined as the lowest VAS score reported by the patient over the course of follow-up. Time to maximal pain reduction was defined as the time at which the patient has the lowest VAS score over the course of the hour follow-up.
次要结局
- adverse effects [Opiate Related Symptom Distress Scale](1 hour post administration)
- patient satisfaction [Interview](1 hour post administration)
