Multimodal analgesia is superior to opiates alone after tibial fracture in patients with substance abuse history

Abstract

Objectives: To evaluate the effectiveness of multimodal analgesia in patients with a tibial shaft fracture. Design: Retrospective review. Setting: Large, urban, academic center. Patients: One hundred thirty-eight patients were evaluated before implementation of multimodal analgesia. Thirty-four patients were evaluated after implementation. All patients were treated operatively with internal fixation for their tibial shaft fracture. Patients with polytrauma were excluded. Intervention: Multimodal analgesia. Main Outcome Measures: Pain levels at rest and with movement were assessed. Morphine milligram equivalents (MMEs) dosed per patient were calculated each day. Length of stay was also documented. Results: After implementation of a multimodal analgesic program, there was a statistically significant decrease in pain score at rest (4.7–4.0, P 5 0.034) and with movement (5.8–4.8, P 5 0.007). MMEs dosed in the multimodal analgesic program correlated with pain score (R2 5 0.5), whereas before implementation of the program, MMEs dosed were not dependent on pain score (R2 5 0.007). Patients with a history of substance abuse had the most profound effect from this paradigm change. For those with a history of substance abuse, treatment of pain using a multimodal approach reduces MMEs dosed and length of stay (5.7–3.1 days, P 5 0.016). Conclusions: Multimodal analgesia improves patient pain scores both at rest and during movement. In patients with a history of substance abuse, multimodal analgesia not only decreases pain but also decreases length of stay and MMEs dosed to levels consistent with someone who does not have a substance abuse history. Level of Evidence: Therapeutic Level III.
