SECONDARY outcome

Timeframe: 5, 10, 15, 20, 30, 45, 60 minutes

Population: One patient in the Ketamine IV push arm was in radiology for the 45 and 60 minute time points. There are 30 rather than 31 participants in the ketamine IV infusion arm because one participant withdrew before the first time point.

The difference in how bothersome (0, not bothersome, to 4, very bothersome, on the Side Effect Rating Scale for Dissociative Anesthetics "SERSDA") the side effects experienced by participants in each arm of the study are at 5, 10, 15, 20, 30, 45, and 60 minutes. "0" (no side effects), "1" (weak), "2" (moderate), "3" ("bothersome") to "4" (very bothersome)

SECONDARY outcome

Timeframe: 5, 10 , 15, 20, 30, 45, 60 minutes

Population: One patient in the Ketamine IV push arm was in radiology for the 45 and 60 minute time points. There are 30 rather than 31 participants in the ketamine IV infusion arm because one participant withdrew before the first time point.

The difference in pain numeric rating score (NRS 0-10) experienced by participants in each arm of the study at 5, 10, 15, 20, 30, 45, and 60 minutes. Pain numeric rating scale from 0 (no pain) to 10 (maximal pain).

Outcome measures

Outcome measures
Measure
Ketamine IV Infusion
n=30 Participants
Ketamine 0.3 mg/kg in 100 mL normal saline minibag infused over 15 minutes. Placebo: 10 mL normal saline in syringe pushed over 1 minute. Masking: placebo normal saline minibags and placebo syringes will appear identical to the normal saline minibus and syringes with ketamine. Ketamine IV Infusion: Ketamine 0.3 mg/kg in 100mL normal saline minibag administered over 15 min and placebo 10 mL normal saline syringe administered over 1 minute.
Ketamine IV Push
n=29 Participants
Ketamine 0.3 mg/kg in a syringe pushed over 1 minutes. Placebo: 100 mL normal saline minibag infused over 15 minutes. Masking: placebo normal saline minibags and placebo syringes will appear identical to the normal saline minibus and syringes with ketamine. Ketamine IV push: Ketamine 0.3 mg/kg in 10 mL normal saline syringe administered over 1 minute and placebo 100mL normal saline minibag administered over 15 min.
