The Effectiveness of Ketamine in Pediatric Acute Deafferentation Pain after Spinal Cord Injury

Figure 2

Average daily NRS pain scores before, during, and after ketamine. Day number −3 corresponds to 3 days preceding ketamine initiation, and day number 1 is the first day of the ketamine treatment. Of note, the patient’s spinal surgery occurred on day −1, and day 1 also represents postoperative day 1 (POD1). Day numbers +1 to +3 refer to the days following ketamine discontinuation. The graph shows a downtrend in average pain scores.
