Injury Patterns of Electric-Scooter Related Trauma: A Systematic Review With Proportion Meta-Analysis.

Electric scooter (ES)-related injuries are increasing but poorly described. Clinicians need more information to be prepared for these patients. We supposed two prevalent patterns of patients: mildly injured (predominant upper-limb injuries) and severely injured (predominant head trauma). This study aims to understand the frequency of ES-related injuries and patients' characteristics despite the heterogeneity of data currently available. A systematic review with a proportion meta-analysis was conducted on studies with a multidisciplinary description of ES-related injuries in adult patients (PROSPERO-ID: CRD42022341241). Articles from inception to April 2023 were identified in MEDLINE, Embase, and Cochrane's databases. The risk of bias was evaluated using ROBINS-I. Twenty-five observational studies with 5387 patients were included in the meta-analysis, depending on reported data. Upper-limb (31.8%) and head (19.5%) injuries are the most frequent (25/25 studies included). When injured while riding, 19.5% of patients are intoxicated with drugs/alcohol, and only 3.9% use a helmet, increasing the possibility of severe injuries. About 80% of patients are victims of spontaneous falls. Half of the patients self-present to the ED, and 69.4% of cases are discharged directly from the ED. Studies' limitations include an overall moderate risk of bias and high heterogeneity. Electric scooter-related accidents are commonly associated with upper-limb injuries but often involve the head. Spontaneous falls are the most common mechanism of injury, probably related to frequent substance abuse and helmet misuse. This hot topic is not adequately investigated due to a lack of data. A prospective registry could fill this gap.

Blunt abdominal trauma: watch and wait.

PURPOSE OF REVIEW: This review examines recent advancements in nonoperative management (NOM) of hemodynamically stable blunt abdominal trauma, focusing on expanding patient selection for observation-first strategies, particularly for high-grade solid organ injuries. RECENT FINDINGS: Advances include a more deliberate nonoperative approach, allowing for broader patient inclusion in diagnostic and interventional angiography. Strict clinical monitoring and appropriate follow-up strategies are crucial to identify early signs of clinical progression and complications. Repeated contrast-enhanced CT (CECT) scan can be used for close observation of high-risk injuries, while the repetition of CECTs may be avoided for lower-risk cases, such as specific high-grade kidney injuries. The role of contrast-enhanced ultrasound (CEUS) in detecting sequelae of nonoperative approaches is still debated and has lot of potential, with ongoing trials exploring possible advantages. SUMMARY: Multidisciplinary trauma teams play a crucial role in nonoperative management, particularly for high-grade injuries. A careful selection of patients is essential to minimize failure rates. Complications of nonoperative and angiographic approaches should be managed according to local expertise.
