Trial Outcomes & Findings for Optimal Dosing of Ketamine for Procedural Sedation and Analgesia in Children (NCT NCT02519595)

NCT ID: NCT02519595

Last Updated: 2016-10-12

Results Overview

Measure sedation depth using Ramsay Sedation Scale. Varies from 1-6 with 1: anxious, agitated, restless 2: Cooperative, oriented, tranquil 3: responsive to commands 4: Brisk response to light glabellar tap or auditory stimulus 5: Sluggish response to light glabellar tap or loud auditory stimulus 6 being no response to light glabellar tap or loud auditory stimulus. Higher the score, greater is the depth of sedation. Use of ketamine usually provides a depth of sedation of 5 or 6.

Participant Flow

Conducted at a level 1 trauma Pediatric Emergency Department from July 1st 2010 to August 31st 2012. We enrolled a convenience sample of eligible patients. Study participants were identified using the electronic medical tracking board which lists the presenting complaint and after need for IV ketamine sedation was established with physician.

11 consented patients were excluded as sedation and procedure was performed in the operating room rather than in the Emergency Department

PRIMARY outcome

Timeframe: Participants will be assessed after study drug adminsitration and the maximum depth of sedation achieved recorded. Approximately 2 hours

Measure sedation depth using Ramsay Sedation Scale. Varies from 1-6 with 1: anxious, agitated, restless 2: Cooperative, oriented, tranquil 3: responsive to commands 4: Brisk response to light glabellar tap or auditory stimulus 5: Sluggish response to light glabellar tap or loud auditory stimulus 6 being no response to light glabellar tap or loud auditory stimulus. Higher the score, greater is the depth of sedation. Use of ketamine usually provides a depth of sedation of 5 or 6.

PRIMARY outcome

Timeframe: Patients will be assessed during the procedure after administration of sedation medicaiton. Approximately 30 minutes

Measure pain using self reported Wong Baker faces pain rating scale prior to sedation, during sedation and prior to discharge.The scale shows a series of faces ranging from a happy face at 0, "No hurt" to a crying face at 10 "Hurts worst". The patient must choose the face that best describes how they are feeling. The score has values of 0(no hurt), 2(hurts little bit), 4(hurts little more), 6(hurts even more), 8(hurts whole lot),10 (hurts worst). The patient chooses one number that describes the pain best (eg. Either a 2 or 4).

SECONDARY outcome

Timeframe: Patients will be assessed during the length of time from administration of sedation medication until ready for discharge, Approximately 3 hours

Length of sedation was defined as the time duration from the administration of study medication until ready for discharge using standardized discharge criteria (Aldrete scoring \>9) followed at our institution.
