Analgesic Effect of Acupuncture for Patients With Rib Fractures

Study Overview
=================
Brief Summary
-----------------
Traumatic rib fractures are common, resulting from significant forces impacting on the chest, and are associated with significant morbidity and mortality. Acute pain management in inpatients with traumatic rib fractures has been highly emphasized by practitioners. Inappropriate analgesia may cause respiratory complications, including pneumonia, atelectasis, acute respiratory distress syndrome, and prolonged hospital stay. These may be prevented or reduced by good analgesic therapy. This study is aimed to investigate the analgesic effect of acupuncture on traumatic rib fractures.

Detailed Description
-----------------
This open-label, randomized controlled trial will involve 150 patients who have traumatic rib fractures. Subjects are randomly assigned to acupuncture group, laser acupuncture group or sham laser acupuncture group with a 1:1:1 ratio. The intervention will be performed on the consecutive three day after allocation. Bilateral LI4 (Hegu), SJ6 (Zhigou), ST36 (Zusanli) and GB34 (Yanglingquan) are used for each group. The traditional acupuncture group will be performed by inserting needles to a depth of 15-35 mm and last for 15 min. The laser acupuncture will be performed with the gallium aluminum arsenide LaserPen, which delivered 0.375 J of energy at each of the acupoints. Subjects in the control group underwent sham laser acupuncture treatment without any laser output. The acupuncture points, application duration, and total number of treatments were similar to those in the laser acupuncture group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Traditional acupuncture (TA)<br>The subject will receive real acupuncture treatment once per day for 3 days after enrollment. | Procedure: Traditional acupuncture (TA)<br>* Procedure: real acupuncture. Eight disposable, single use, sterilized, stainless steel needles are inserted at each session, and the bilateral LI4 (Hegu), SJ6 (Zhigou), ST36 (Zusanli) and GB34 (Yanglingquan) are used for acupuncture treatment. The acupuncture needles are to be inserted to a depth of 15-35 mm. All needles are rotated manually at least once at each session to elicit needle sensation (De qi). The needle retention time is 15 min.<br>|
| Active Comparator: Laser acupuncture (LA)<br>The subject will receive laser acupuncture treatment once per day for 3 days after enrollment. | Procedure: Laser acupuncture (LA)<br>* Procedure: laser acupuncture. Participants allocated to the LA group receive laser acupuncture treatment at the same acupoints used in acupuncture group. The laser acupuncture therapy will be performed with the gallium aluminum arsenide LaserPen (maximal power, 150 mW; wavelength, 810 nm; area of probe, 0.03 cm2; power density, 5 W/cm2; pulsed wave; and Bahr frequencies [B1: 599.5 Hz, B2: 1199 Hz, B3: 2398 Hz, B4: 4776 Hz, B5: 9552 Hz, B6: 19,104 Hz, and B7: 38,208 Hz]; RJ-Laser, Reimers & Janssen GmbH, Waldkirch, Germany). The laser will be applied to each point for 5 seconds, which delivered 0.375 J of energy at each of the acupoints: LI4 (Hegu, B3), SJ6 (Zhigou, B3), ST36 (Zusanli, B2) and GB34 (Yanglingquan, B2).<br>|
| Placebo Comparator: Sham laser acupuncture (SLA)<br>The subject will receive sham laser acupuncture treatment once per day for 3 days after enrollment. | Procedure: Sham laser acupuncture (SLA)<br>* Procedure: sham laser acupuncture. Subjects in the control group receive sham laser acupuncture treatment without any laser output. The acupuncture points, application duration, and total number of treatments were similar to those in the LA group.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Efficacy of pain relief | Maximal pain intensity (Numerical Rating Scale; NRS: 0-10) evaluated by participants themselves during deep breathing, coughing, and turning over in bed. | The NRS will be assessed at Day 1, Day 2 and DAY 3 pretreatment and posttreatment in the morning (8:00-10:00) and evening (15:00-17:00), respectively. Primary outcome is the change of NRS score on DAY 1 pretreatment and DAY 3 post treatment. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sustained maximal inspiration lung volumes | Sustained maximal inspiration lung volumes | The sustained maximal inspiration lung volumes will be assessed at Day 1, Day 2 and DAY 3 pretreatment and posttreatment in the morning (8:00-10:00) and evening (15:00-17:00), respectively. | 
| Number of cases with pulmonary complications | Pulmonary complications including pneumonia, atelectasis, pleural effusion, acute respiratory distress syndrome, and respiratory failure. | Follow-up for one month | 
| Saliva cortisol level | Saliva cortisol level | The saliva cortisol level will be assessed at Day 1, Day 2 and DAY 3 pretreatment and posttreatment in the morning (8:00-10:00) and evening (15:00-17:00), respectively. | 
| Heart rate variation | Heart rate variation | The heart rate variation will be assessed at Day 1, Day 2 and DAY 3 pretreatment and posttreatment in the morning (8:00-10:00) and evening (15:00-17:00), respectively. | 
| The dose of narcotic and non-narcotic analgesics used | Record the use of narcotic and non narcotic analgesics based on chart reviews. Narcotic drugs include codeine, tramadol, and morphine. Non narcotic drugs include acetaminophen, ibuprofen, diclofenac, ketoprofen, mefenamic acid, and parecoxib. | Record the medication use for 2 weeks after participant enrolled |
