Surgical management of multiple rib fractures in polytrauma patients: semi-damage control surgery.

Background: To investigate the timing and extent of surgery for rib fractures in polytrauma patients. Methods: Data from polytrauma patients who underwent early and partial rib fracture fixation after successful resuscitation were retrospectively analyzed. The study encompassed demographic data, clinical data, and outcomes. Results: In total, 71 patients with polytrauma were included. ISS ranged from 16 to 50 with a mean score of 25.3±7.5. The median lactate level was 3.6 mmol/L (IQR: 3.1 to 4.5), the median base deficit (BD) was 8.2 mmol/L (IQR: 6.4 to 9.8) and the shock index (SI) median was 1.2 (IQR: 0.9 to 1.3). Total fractured ribs in 71 patients were 726; individually, the minimum and maximum number of fractured ribs was 3 and 22, respectively (median, 10; mean, 10.2 ± 4.0). The average time to surgery was 42.9±42.6 h. Specifically, 41(57.7%) received the surgery within 24h and 52 (73.2%) patients received the surgery within 3 days following successful resuscitation. A total of 246 (33.9%) ribs underwent open reduction and internal fixation with plate, 3.46 ribs for each patient, with high frequencies of the 6th (49, 19.9%), 5th (46, 18.7%), 4th and 7th ribs (both 36, 14.6%). The average length of ICU stay was 11.5 ± 7.5 days and the duration of hospitalization was 16.3 ± 9.9 days. No surgical site infection or mortality was observed. Conclusions: Early and partial rib fracture fixation to restore the relative stability of the thorax is safe and effective for polytrauma patients after successful resuscitation. This surgery strategy is called semi-damage control surgery.
