Effect of a Multimodal Pain Regimen on Pain Control, Patient Satisfaction and Narcotic Use in Orthopaedic Trauma Patients

Effect of a Multimodal Pain Regimen on Pain Control, Patient Satisfaction and Narcotic Use in Orthopaedic Trauma Patients

The study is a prospective, randomized, open-label comparison of a multimodal regimen and a standard, narcotic-based regimen for postoperative pain control in patients undergoing surgery for an operatively indicated, isolated extremity fracture. The investigators will be measuring pain levels, narcotic use, patient satisfaction, patient reported function, adverse events and fracture union. The investigators hypothesize that this multimodal regimen will lead to improved pain, less narcotic use and improved satisfaction as compared to the standard regimen.

Patients will be assessed for inclusion or exclusion during admission to the hospital or during evaluation in the clinic or emergency room for an isolated extremity fracture for which surgery is indicated. Once enrolled in the study and consent obtained, patients will be randomized into either the standard therapy group or the multimodal therapy group using permuted block randomization based on injury site. The sites of fracture are as follows: wrist/hand/forearm elbow/upper arm/shoulder acetabulum/pelvis foot/ankle patella/tibia (shaft, proximal) femur (proximal to distal) The investigators have assumed that these distinct areas result in a similar amount of disability and pain as compared to the other sites. This is an attempt to mitigate the possible confounder of disproportionate numbers of more painful or more debilitating injuries falling in one study group compared to another. Pre-operatively, patient demographic data will be recording including age, gender, BMI, hand dominance, occupation, use of tobacco/alcohol/illicit drugs, use of assistive devices, relevant comorbidities (i.e., diabetes), site of injury, mechanism and energy (high or low). If there is to be a delay between initial presentation and surgery, as is often the case for distal radius or ankle fractures, among others, multimodal patients will begin their therapy immediately after evaluation. Thus, they will be started on scheduled 1000mg acetaminophen and 100mg gabapentin both three times daily. They will also be provided an 5mg oxycodone prescription with instructions to take 1-3 tablets every 4 hours as needed for pain. Standard therapy patients will be prescribed oxycodone alone, using the same parameters, with the ability to take acetaminophen on an as needed basis. Pre-operatively, multimodal patients will receive 1000mg IV acetaminophen, 100mg PO gabapentin and 400mg PO celecoxib. All patients will have a peripheral nerve block placed when indicated, to confirm to the investigators standard of care. Patients will then undergo surgery with the investigators standardized anesthesia protocol as described in the protocol. Intraoperatively, multimodal patients will receive 8mg of IV dexamethasone. Post-operatively, multimodal patients will be given 1000mg acetaminophen three times daily for the duration of their narcotic use and 100mg Gabapentin three times daily for 1 week, which will be titrated to 200mg three times daily for 1 additional week. They will also receive an oxycodone prescription as described previously. Standard therapy patients will be given an oxycodone prescription alone with the advice to take tylenol on an as needed basis not to exceed 4000mg/day. No placebo medications will be used as this is an open label study. Patients will be instructed to avoid all anti-inflammatory medications. All patients across groups will be given aspirin 81mg for deep vein thrombosis prophylaxis if they suffered a lower extremity fracture. Should a patient require an alternative deep vein thrombosis prophylaxis regimen due to an allergy to aspirin or a personal history of deep vein thromboses, low molecular weight heparin will be used. Patients will be given a diary to record their daily narcotic use, daily minimum, maximum and average pain scores using a visual analog scale and any side effects. Patients will be provided the contact information of the attending surgeon's nurse to report any serious allergies or adverse effects of the study medications. A case by case decision will be made to either continue the protocol or to drop the patient from the study and make needed medications changes. Patients will be followed at defined time points after surgery including, 2 wks, 6wks, 3mo and 6mo. At their 2 wk follow up visit they will fill out the Short Musculoskeletal Function Assessment for their preoperative functional state as well as the American Pain Society Patient Satisfaction Questionnaire. These will again be filled out at their 3 and 6 month visits. Union will be assessed at their 3 and 6 month visits by a third party, blinded observed. It will be defined as three cortices of bridging callus on 2 orthogonal views. Once fracture union occurs or nonunion is identified control patients will be allowed to use non steroidal anti-inflammatories as needed. Time to return to work/normal activity, total narcotic usage and duration of narcotic use will also be recorded.

Oxycodone 5-15mg PO q4hrs prn pre- and post-op, Acetaminophen 1000mg IV once pre-op, Acetaminophen 1000mg PO q8hrs pre-op and x2 weeks post op, prn thereafter, Gabapentin 100mg/200mg PO a8hrs pre-op and x2 weeks post op, Dexamethasone 8mg IV once intra-op, Celecoxib 400mg PO once pre-op.

Measurement of both daily narcotic use in milligrams as well as the duration of narcotic treatment in days.
