Intranasal Ketorolac for Acute Pain in Adult Emergency Department Patients.

Abstract

Pain is a common complaint in the emergency department. An alternative to opioids is desirable. Oral medications are not feasible with gastrointestinal disorders or NPO. Intravenous medications require skill and time. Intravenous/intramuscular medications are painful with potential needlestick injury. Intranasal medications have rapid onset, easy administration, do not need skilled providers, and no risk of needlestick injury. A total of 28 adults with acute pain (numeric rating scale ≥ 4) received intranasal ketorolac. Numeric rating scale decreased in all: 32% complete pain relief, median (interquartile range) decrease -5 (-6.8 to -4) (p < .001). Pain relief onset was median [interquartile range] 5 (2.3, 15.0) min. Vital signs remained normal. There were no nasal mucosal changes, no complications. Minor side effects, mostly nasal burning, in 43%, resolved within 5 min. Patients and nurses were satisfied with intranasal ketorolac, and would use it again. Intranasal ketorolac had a rapid onset, was effective, safe, well tolerated with minor side effects that resolved quickly.
