Background This study aimed to determine whether surgery within 24 h improves the neurological prognosis and reduces the complications associated with surgery for traumatic severe cervical spinal cord injury (CSCI). Methods The data of 42 patients with traumatic severe CSCI with American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades of A–B who underwent surgery between December 2007 and May 2018 were retrospectively reviewed. The participants were divided into early surgery (< 24 h) and late surgery (> 24 h) groups. Using inverse probability of treatment weighting (IPTW) with propensity score adjustment for confounding factors, the AIS grade before and 1 month following surgical treatment as the primary outcome were compared. The secondary outcome was the intensive care unit length of stay (ICU-LOS) and occurrence of respiratory complications and cardiac arrest. Results In the early surgery group (n = 32, 76%), the average time to surgery was 10.25 h (4–23 h). The IPTW analysis indicated significant differences in neurological improvement according to the AIS grade at 1 month following surgery (odds ratio [OR]: 17.1 95% confidence interval [Cl]: 1.9–156.7, p = 0.012), ICU-LOS > 7 days (OR: 0.14 95% Cl: 0.02–0.90, p = 0.04), respiratory complications (OR: 0.08 95% Cl: 0.01–0.73, p = 0.03), and cardiac arrest (OR: 0.13 95% Cl: 0.02–0.85, p = 0.03). Conclusions Early surgery (within 24 h) for traumatic severe CSCI may be effective in improving the neurological prognosis, and preventing a long ICU-LOS and postoperative complications.
Background: Few studies have examined the impact of chest wall injury on respiratory complications after cardiopulmonary resuscitation. This is due to many confounding factors for the development of complications after cardiopulmonary resuscitation. Accordingly, we investigated the association between multiple rib fractures and the incidence of pneumonia during the post-resuscitation period after adjusting for confounding factors using a propensity score.Methods: This single-centre, retrospective cohort study enrolled adult, non-traumatic, out-of-hospital, cardiac arrest patients who maintained circulation for >48 h between June 2015 and May 2019. Rib fractures were evaluated by computed tomography on the day of hospital admission, and the association with newly developed pneumonia within 7 days of hospitalisation was analysed using propensity score matching with adjustment for variables previously reported to be risk factors for the development of pneumonia.Results: Of the 683 out-of-hospital cardiac arrest patients treated during the study period, 87 eligible cases were enrolled for analysis. Thirty-two patients had multiple rib fractures identified by computed tomography and 35 patients developed pneumonia. The presence of multiple rib fractures was significantly associated with a higher incidence of pneumonia (propensity score-adjusted hazard ratio: 3.51; 95% confidence interval: 1.59–7.72; p=0.002). Consistently, after propensity score matching, the multiple rib fracture group showed significantly shorter pneumonia-free survival than the non-multiple rib fracture group (p<0.01).Conclusion: Multiple rib fractures are independently associated with the development of pneumonia after successful resuscitation.
