Conscious sedation versus rapid sequence intubation for the reduction of native traumatic hip dislocation

Background: Traumatic hip dislocations (THD) are a medical emergency. There is debate whether the painful reduction of a dislocated hip should be first attempted using primary conscious sedation (PCS) or primary general anesthesia (PGA) Methods: All cases of native THD from 2006 to 2015 in the trauma registry of a level 1 trauma center were reviewed. The primary outcome was successful reduction of the THD. Results: 67 patients had a native, meaning not a hip prosthesis, THD. 34 (50.7%) patients had successful PCS, 12 (17.9%) failed PCS and underwent reduction following PGA. 21 (31.3%) underwent PGA. Patients in the PGA group were more severely injured. Time to reduction greater than 6 h was associated with PCS failure (Odds ratio (95% confidence interval) 19.75 (2.06,189.10) p = 0.01). Conclusion: Clinicians treating patients with a THD can utilize either PCS or PGA with many patients safely reduced under PCS. However, patients whose hip have been dislocated for more than 6 h are at risk for failure with PCS, and are good candidates for PGA.
