Managing acute postoperative pain: is 3 hours too long?

This case study discusses a 64-year-old opioid-tolerant patient who underwent amputation below the left knee and received pain management in the PACU. The patient's self-reported pain level remained 9 on a 0 to 10 scale despite having received a total of 62 mg of morphine sulfate (MSO 4 ) and 60 mg of ketorolac in just less than 3 hours. The patient's facial expression corresponded to a score of 4 to 5 based on the Wong-Baker Faces Pain Scale.
