Press tack needle stimulation for blunt chest trauma: a randomized double-blind control trial.

Abstract

OBJECTIVESBlunt chest trauma is often associated with severe pain, reduced lung function and decreased sleep quality. This study aims to investigate the immediate and long-term effect of acupuncture on these factors using a randomized control double-blind design.METHODSA total of 72 patients were randomized into 2 groups: treatment group (press tack acupuncture) and control group (press tack placebo). The face rating scale, numerical rating scale (NRS), portable incentive spirometer and Verran Snyder-Halpern sleep scale were measured at baseline, immediately after the intervention, and at the 4th day, with 2-weeks and 3-months follow-ups.RESULTSThere were no significant changes between the groups at the baseline measurements, with the exception of hypertension comorbidity. Immediately after the intervention and on the 4th day follow-up, the patients in the treatment group showed a significantly lower face rating scale when compared to the control (P < 0.05). There were no significant changes in any of the other measurements between the groups (P > 0.05). Subgroup analysis revealed that the NRS for turn over on the 4th day was reduced significantly in the treatment group of patients without lung contusion (P < 0.05). For patients without pleural drainage, cough NRS in the treatment group was significantly reduced in the 2-week follow-up (P < 0.05).CONCLUSIONSThis study showed that press tack acupuncture effects on pain reduction were inconclusive. However, future studies on the effect of acupuncture on blunt chest trauma patients are needed.Clinical trial registrationclinicaltirl.gov: NCT04318496.
