A kicking, spitting and struggling 7-year-old boy rapidly became cooperative following emergency department intranasal administration of lorazepam, according to a case report in the Annals of Emergency Medicine.

As Dr. Joan S. Bregstein told Reuters Health by email, “The use of the intranasal route to administer calming medication to young ED patients with behavioral issues has potential to be a real game changer for these patients. It means that we can possibly save them from receiving an intramuscular medication (IM) that could certainly be an additional source of agitation.”

In their online report, Dr. Bregstein and colleagues at Columbia University College of Physicians and Surgeons, New York City, note that such patients presenting for psychiatric care are often sedated by the IM route “which can be painful and is associated with the risk of needlestick injuries to both hospital personnel and patients.”

The boy, who had a long-standing history of anxiety and oppositional defiant disorder, presented to the ED following aggression and violent behavior at home. His mood showed no improvement in the ED and he threatened the medical staff with death. Physical and chemical restraints were required.

Hospital personnel donned masks with eye shields, security guards provided physical restraint and stabilization of the patient’s head, and intranasal lorazepam (2 mg/mL) was administered into both nares using a mucosal atomization device.

Five minutes later he was calm and cooperative and sitting on a stretcher without physical restraints. His peaceful behavior lasted for about 90 minutes at which point he started kicking and biting the security guards. He was then given IM haloperidol and diphenhydramine and subsequently slept through the night.

The following evening while awaiting inpatient admission, his anger erupted again and he attempted to escape from the ED. Physical and chemical restraints were required once more and intranasal lorazepam was repeated at a higher doze of 3 mg/kg. Again the patient was calm and cooperative within 5 minutes and soon fell asleep. When he awoke he was still calm and remained so for the whole 24 hours of his subsequent ED stay.

The investigators observe that sedatives such as lorazepam “can reach peak serum concentrations up to 6 times faster when administered intranasally compared with intramuscularly.”

The intranasal route, continued Dr. Bregstein, “has the potential for faster medication delivery and response, and the needle-less intranasal route is a safer alternative for ED providers administering the medication.”

She cautioned, “There’s still work to be done before intranasal lorazepam can be our go-to anxiolytic for this type of ED patient, but we are very encouraged that, at least in this one patient, IN lorazepam seems to have been very successful, safe and well-received.”
