Characteristics of Orbital Injuries Associated with Maxillofacial Trauma.

INTRODUCTION: The incidence of ocular injury associated with maxillofacial trauma remains poorly defined, with reported rates ranging from 0.8% to 92%. Our study aims to more accurately characterize ocular injuries associated with midface fractures. METHODS: We performed a retrospective review of 1677 patients from 2015 to 2020 with midface fractures at a Level I trauma center. Isolated nasal bone and frontal process of the maxilla fractures were excluded. Demographic information, mechanism of injury, need for surgery, and ophthalmologic findings were documented. Statistical analysis was conducted using SPSS. RESULTS: 773 patients between the ages of 15 and 92 were identified. Trauma most commonly resulted from assault (63.8%). The association between the mechanism of injury and ocular injury was statistically significant (p = 0.003), with 78.6% of gunshot wounds and 44.3% of assault patients having an ocular injury. The Ophthalmology service evaluated 62.6% of cases preoperatively. Minor ocular injury occurred in 36% of patients, including 46.1% of isolated orbital floor, and 28.2% of zygomaticomaxillary complex fractures. Major ocular injury occurred in 10.5% of patients. CONCLUSIONS: Over 10% of patients with midface fractures were found to have major ocular injuries. Ophthalmologic exams should be performed for all patients with midface fractures to guide clinical decision making and prevent further intraoperative ocular insults. LEVEL OF EVIDENCE: Level 4. This study represents a retrospective cohort study analyzing ocular injuries detected in patients presenting to a Level I trauma center with maxillofacial fractures between 2015 and 2020 Laryngoscope, 133:1624-1629, 2023.

Postoperative Infections are Associated with Increased Risk of Cardiac Events in Vascular Patients.

BACKGROUND: Despite advances in perioperative care, the rate of cardiac events in vascular patients remains high. We have previously shown that infections in trauma patients are associated with higher rates of subsequent cardiac complications, likely due to the additive effect of a second hit of an infection following the trauma. The aim of this study was to investigate whether there is an association between postoperative infections and subsequent cardiac events in vascular patients. METHODS: A 5-year retrospective review of demographics, comorbidities, operative interventions, infectious, and cardiac events in all vascular patients who underwent an operative intervention at a single tertiary referral center was performed. In patients with clinical suspicion of myocardial injury, myocardial damage was defined as troponin >0.15 ng/mL and myocardial infarction (MI) as troponin >1 ng/mL. Pneumonia was diagnosed using bronchoalveolar lavage (BAL) and considered positive if BAL fluid culture contained >10,000 colony-forming units (cfu). Urinary tract infection (UTI) was diagnosed if the urine culture contained >100,000 cfu. All other infections were diagnosed by culture data. Regression analysis was performed to assess risk of cardiac events as a function of infections adjusting for age, gender, and comorbidities. RESULTS: We analyzed 1,835 vascular operative interventions with the mean age of the cohort 65.5 years (65.9% male). The overall infection rate was 13.2%, with UTI being the most common (60.3%). The overall rate of myocardial damage was 8.1% and the rate of MI 3.8%. Rates of both myocardial damage (15.5 vs. 7.7%; P = 0.0015) and MI (7.1 vs. 3.4%; P = 0.018) were significantly higher in patients with infections, compared to those without infections. Adjusting for age, gender, medical comorbidities, open versus endovascular cases as well as statin and steroid use, patients with UTI were more likely to subsequently develop either myocardial damage (odds ratio [OR] = 3.57 [95% confidence interval = 1.51-8.45]) or MI (OR = 4.20 [1.23-14.3]). A similar association was noted between any infections and either myocardial damage (OR = 2.97 [1.32-6.65]) or MI (OR = 4.31 [1.44-12.94]). CONCLUSIONS: We herein describe an association between postoperative infections, most commonly UTI, and subsequent cardiac events. Efforts should be made to minimize the risk of developing infections to ensure cardioprotection in vascular patients during perioperative period.
