Reducing Ketamine-Induced Agitation, by Midazolam or Haloperidol Premedication After Adult Procedural Sedation

November 4, 2017 updated by: Pooya Payandemehr, Tehran University of Medical Sciences

A Comparison of Midazolam or Haloperidol Premedication Versus Placebo for Reducing Ketamine Induced Agitation After Adult Procedural Sedation in the Emergency Department

Ketamine is the cornerstone of procedural sedation in emergency department but ketamine induced agitation has limited its usage by many physicians. As a solution, some propose using midazolam or haloperidol before ketamine injection. In this randomized double blind clinical trial, patients who are eligible for sedation by ketamine are allocated in 3 groups. In first group, the patients will receive 0.05 mg/kg midazolam, in second group 5 mg of haloperidol and in 3rd group a placebo five minutes before receiving the sedative dose of ketamine (1 mg/kg). The patients are assessed for agitation during and after the procedure the clinician's satisfaction with sedation instrument is evaluated after the procedure.

As a solution, some propose using midazolam or haloperidol before ketamine injection. In this randomized double blind clinical trial, patients who are eligible for sedation by ketamine are allocated in 3 groups.

The patients are assessed for agitation during and after the procedure the clinician's satisfaction with sedation instrument is evaluated after the procedure. The investigator will fill standard questionnaires for agitation assessment (Richmond Agitation-Sedation Scale and Pittsburgh Agitation Scale).

Intervention / Treatment
Placebo Comparator: placebo
To do procedural sedation and analgesia in this group, the patients will receive 2 intravenous injections of distilled water (one 2 ml and the other 0.05 cc/kg) 5 minutes before receiving a sedative dose of 1 mg/kg IV ketamine.

Ketamine is routinely used for all procedural sedation in the patients.
