Clinical Trial Summary

Observational study to assess efficacy of IV ketamine bolus when used in the post anesthesia recovery unit for uncontrolled pain despite use of opioids.

Description:

In this observational study, the investigators will monitor all patients with significant pain after any non-cardiac surgical intervention at the University of Alberta Hospital. After receiving an adequate dose of potent opioids (hydromorphone, morphine), the participants will receive up to 0,2-0,25 mg/kg IV ketamine bolus. In our center these boluses are given with 10-20mg increments. The adequate dose of opioids will be determined by the attending anesthesiologist, depending on what patients received intraoperatively and on their comorbidities. Pain scores will be assessed before and after administration of this drug. The incidence of any side effect after ketamine administration will be documented.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Reduction in pain score after ketamine use in PACU	The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain. It is what is used most often in our recovery room for pain assessment. A score of 0/10 means no pain, and 10/10 means worst pain.	in the immediate post-operative period in recovery room
Secondary	Incidence of side effects after ketamine use		in the immediate post-operative period in recovery room
