Impact of Cardiac Pacemaker Implantation in Patients with Acute Traumatic Cervical Spinal Cord Injury

Background Cardiac pacemaker implantation may be indicated in patients with refractory bradycardia following a cervical spinal cord injury (CSCI). However, evidence about the impact of this procedure on outcomes is lacking. We planned a study to assess whether the implantation of a pacemaker would decrease mortality and hospital resource utilization in patients with CSCI. Methods Adult patients with CSCI in the Trauma Quality Improvement Program (TQIP) database between 2016 and 2019 were retrospectively analyzed. Patients were divided into “pacemaker” and “non-pacemaker” groups, and their baseline characteristics and clinical outcomes were analyzed. Results A total of 6774 cases were analyzed. The pacemaker group showed higher in-hospital rates of cardiac arrest, myocardial infarction, and longer duration of mechanical ventilation and ICU stay than the non-pacemaker group. Nevertheless, pacemaker placement was associated with a significant decrease in mortality (4.2% vs 26.0%, P < .01). Conclusions Patients with CSCI requiring a pacemaker placement had better survival than those treated without a pacemaker. Pacemaker implantation should be highly considered in patients who develop refractory bradycardia after CSCI.
