Intrathoracic surgical stabilization of rib fractures allows for a novel approach to rib fracture repair. This approach can help minimize muscle disruption, which may improve patient recovery compared with traditional extrathoracic plating. We hypothesized patients undergoing intrathoracic plating (ITP) to have a shorter length of stay (LOS) and intensive care unit (ICU) LOS compared with extrathoracic plating (ETP). METHODS:A prospective observational paradigm shift study was performed from November 2017 until September 2021. Patients 18 and older who underwent surgical stabilization of rib fractures were included. Patients with ahead Abbreviated Injury Scale score ≥3 were excluded. Patients undergoing ETP (July 2017 to October 2019) were compared with ITP (November 2019 to September 2021) with Pearson χ 2 tests and Mann-Whitney U tests, with the primary outcome being LOS and ICU LOS. RESULTS:Ninety-six patients were included, 59 (61%) underwent ETP and 37 (38%) underwent ITP. The most common mechanism of injury was motor vehicle collision (29%) followed by falls (23%). There were no differences between groups in age, comorbidities, insurance, discharge disposition and injury severity score (18 vs. 19, p = 0.89). Intrathoracic plating had a shorter LOS (10 days vs. 8 days, p = 0.04) when compared with ETP but no difference in ICU LOS (4 days vs. 3 days, p = 0.12) and ventilator days. Extrathoracic plating patients more commonly received epidural anesthesia (56% vs. 24%, p < 0.001) and intercostal nerve block (56% vs. 29%, p = 0.01) compared with ITP. However, there was no difference in median morphine equivalents between cohorts.Operative time was shorter for ITP with ETP (279 minutes vs. 188 minutes, p < 0.001) after adjusting for numbers of ribs fixed. CONCLUSION:In this single-center study, patients who underwent ITP had a decreased LOS and operative time in comparison to ETP in patients with similar injury severity. Future prospective multicenter research is needed to confirm these findings and may lead to further adoption of this minimally invasive technique.
Background Pregnant trauma patients (PTPs) undergo observation and fetal monitoring following trauma due to possible fetal delivery (FD) or adverse outcome. There is a paucity of data on PTP outcomes, especially related to risk factors for FD. We aimed to identify predictors of post-traumatic FD in potentially viable pregnancies. Methods All PTPs (≥ 18 years old) with ≥24-weeks gestational age were included in this multicenter retrospective study at 12 Level-I and II trauma centers between 2016-2021. PTPs who underwent FD ((+) FD) were compared to those who did not deliver ((-) FD) during the index hospitalization. Univariate analyses and multivariable logistic regression were performed to identify predictors of FD. Results Of 591 PTPs, 63 (10.7%) underwent FD, with 4 (6.3%) maternal deaths. The (+) FD group was similar in maternal age (27 vs. 28 years, p = 0.310) but had older gestational age (37 vs. 30 weeks, p < 0.001) and higher mean injury severity score (7.0 vs. 1.5, p < 0.001) compared to the (-) FD group. The (+) FD group had higher rates of vaginal bleeding (6.3% vs. 1.1%, p = 0.002), uterine contractions (46% vs. 23.5%, p < 0.001), and abnormal fetal heart tracing (FHT) (54.7% vs. 14.6%, p < 0.001). On multivariate analysis, independent predictors for (+) FD included abdominal injury (OR 4.07, CI 1.11-15.02, p = 0.035), gestational age (OR 1.68 per week ≥24 weeks, CI 1.44-1.95, p < 0.001), abnormal FHT (OR 12.72, CI 5.19-31.17, p < 0.001), and premature rupture of membranes (OR 35.97, CI 7.28-177.74, p < 0.001). Conclusions The FD rate was approximately 10% for PTPs with viable fetal gestational age. Independent risk factors for (+) FD included maternal and fetal factors, many of which are available on initial trauma bay evaluation. These risk factors may help predict FD in the trauma setting and shape future guidelines regarding the recommended observation of PTPs. Level of Evidence Level III, Therapeutic/Care Management
