The anterior compartment is the most frequently missed of the four compartments during lower extremity fasciotomy. This study describes a novel approach that combines sonographic measurements and physical examination landmarks to accurately identify the anterior compartment. <strong>Materials and Methods:</strong> This study was conducted as a prospective anatomical study of 94 volunteers at a single institution. Physical exam and sonographic methods were utilized to derive measurements of the anterior compartment, followed by biometric and validation data. <strong>Results:</strong> Volunteers for the derivation and validation phases of study were similar regarding gender, height and weight, age, and BMI. The derivation set revealed the distance to the anterior compartment to be 2.77 cm (median 2.6 cm, range 1.5 - 5.4 cm) from the mid-axial line and resulted in identification of the anterior compartment 100% of the time (p < 0.001). Findings were reproducible in the internal validation set with 100% accuracy. <strong>Conclusion:</strong> The fascial planes of the anterior compartment can be identified with 100% accuracy when utilizing physical examination and sonographic methods. This can serve as a foundation for future studies evaluating ways to reduce of the number of missed anterior compartment fasciotomies in the setting of ACS.展开更多

The objective was to determine the characteristics and frequency of alcohol and poly-drug combinations in patients triaged by Trauma Team Activation (TTA) codes. <strong>Methods:</strong> A retrospective study of a Level I hospital trauma registry was initiated with 14,972 patients of whom 7028 (47%) were Substance Users (SU). There were 10,369 TTA patients: 5396 (52%) were SU, and 4603 (31%) non-TTA patients, of whom 1632 (35.5%) were SU. Inclusion criteria were: age ≥14 years old, blood alcohol level and Urine Drug Screen (UDS) documentation, Injury Severity Score (ISS), TTA code, hospital charges and Length of Hospitalization (LOS). Statistical analyses were performed with one-way ANOVA, Maximum Likelihood chi squared, and Mann-Whitney U tests. <strong>Results:</strong> The median ISS was 5 for both groups. TTA patients were younger than non-TTA patients (median 33 years versus 41 years). Mortality was significantly higher for TTA (4.7%) than for non-TTA (0.7%) patients. From 2010-2013 to 2014-2018, all substance users had a significant decrease in alcohol only use (58.0% to 42.0%) with an increase in single drug (42.0% to 58.0%) and poly-drug use (36.9% to 63.1%), <em>p</em> < 0.0001. For all SU patients (TTA and non-TTA), the major single drugs used were opiates (19.9%), cannabinoids (THC) (15.2%), benzodiazepines (7.7%), amphetamines (6.6%), and cocaine (2.5%). The major poly-drugs were: opiates/THC (4.7%), opiates/benzodiazepines (4.6%), THC/amphetamines (3.1%), THC/benzodiazepines (2.2%). <strong>Conclusions:</strong> By trauma activation code designation, the TTA group had most of the positive alcohol and drug screens in this study. Since the change in mandated opioid prescription practices in 2014, this study showed increased poly-drug use (two to six-drug combinations) in urban trauma patients between 2014-2018. Opioids and cannabinoids continued to be the most frequently used drugs singly and in combinations.展开更多
