Adjunctive Atropine During Ketamine Sedation

This study has been completed.

Last verified: August 2012
  • Ketamine seems an obvious choice in the setting of an emergency department
  • Ketamine leads to increased production of salivary and tracheal secretions
  • Antisialagogues(atropine)therefore have been recommended as a routine adjunct
  • We compare atropine with placebo as an adjunct to ketamine sedation in children undergoing primary closure of lacerated wound

Primary Outcome Measures:
  • Hypersalivation(VAS) [ Time Frame: During procedure ]

Secondary Outcome Measures:
  • Sedation scale [ Time Frame: before, during procedure, before discharge ]
  • Pain scale [ Time Frame: before, during procedure, before discharge ]
  • Complication [ Time Frame: during procedure and bedore discharge and 1day after discharge ]

Enrollment: 140
Study Start Date: August 2008
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Atropine
Atropine 0.01mg/kg IV
Drug: Atropine
Ketamine 2mg/kg IV + Atropine 0.01mg/kg or Same volume of Normal saline
Placebo Comparator: Normal saline
Same volume of atropine
Drug: Atropine
Ketamine 2mg/kg IV + Atropine 0.01mg/kg or Same volume of Normal saline

Detailed Description:

The degree of secretion was significantly less in the atropine group compared with the control group at the end of the procedure (VAS score: 16.5 ± 9.9 vs. 27.0 ± 15.9, atropine vs. control, p = 0.00). The change in the degree of secretion between the start and end of the procedure was significantly greater in the atropine group than in the control group (p = 0.00) (Fig. 2). However, the frequency of hypersalivation as predefined (VAS score ≥50) did not differ between the groups (p = 0.06).

The only complication that differed significantly between the two groups was tachycardia (p > 0.05). Complications such as aspiration, laryngospasm, and apnea were not documented in the hospital. There were fewer interventions for hypersalivation in the atropine group, but the difference was not significant (p > 0.05). As interventions, O2 administration and endotracheal intubation were not needed. After discharge, the control patients tended to have more complaints of nausea, vomiting, and ataxia, although the difference was not significant (p > 0.05) Heart rate was increased significantly in the atropine group (p = 0.00). The frequency of tachycardia according to patient age was also significantly higher in the atropine group than in the control group (p = 0.00)
