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

Phase 4
Completed
Conditions
Ketamine Induced Agitation
Interventions
Registration Number
NCT02909465
Lead Sponsor
Tehran University of Medical Sciences
Brief Summary

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.

Detailed Description

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.

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).

Primary Outcome Measures
NameTimeMethod
agitationstarts at the time of Ketamine injection through recovery period(maximum of 2 hours)

assessed by Pittsburgh Agitation Scale(scoring 0 to 16).

Pittsburgh Agitation Scale(scoring 0 to 16) is a valid and reliable instrument to assess agitation severity of inpatients.

level of sedation30 minutes after Ketamine injection

assessed by Richmond Agitation-Sedation Scale(scoring -5 to +4).

Richmond Agitation-Sedation Scale(scoring -5 to +4) is a valid and reliable instrument to assess level of sedation and agitated behavior during sedation.

Secondary Outcome Measures
NameTimeMethod
clinician's satisfactionstarts at the time of Ketamine injection through recovery period(maximum of 2 hours)

assessed by a Clinician Satisfaction with Sedation Instrument(CSSI) questionnaire
