Background: Foreign body aspiration is a common life-threatening event in young children. Tracheobronchial foreign body removal is usually performed by rigid tracheobronchoscopy under general anesthesia. Anesthetic and ventilation techniques vary greatly among anesthesiologists and institutions. In the present retrospective study, we report our anesthetic experience over 5 years. We describe complications and outcomes and analyze the clinical characteristics of anesthesia and ventilation.
Methods: We retrospectively reviewed relevant clinical findings of 586 pediatric patients treated with rigid tracheobronchoscopy under general anesthesia. All procedures were performed under inhaled sevoflurane anesthesia combined with remifentanil infusion, with spontaneous respiration assisted by high-frequency jet ventilation (HFJV) and topical airway anesthesia.
Results: Among 586 patients, the foreign body was successfully removed by rigid tracheobronchoscopy in 558 patients, and no foreign body was found in 28 patients. Laryngospasm was observed during the procedure in five patients. Hypoxemia was observed in 15 patients (2.6%). No severe complications or deaths occurred. The mean operation time was 22 min and the average hospital stay was 2 days.
Conclusion: Inhaled sevoflurane anesthesia combined with remifentanil infusion, with spontaneous respiration assisted by HFJV and topical airway anesthesia, is safe and effective for tracheobronchial foreign body removal.

The development of small-diameter vascular grafts (SDVGs) still faces significant challenges, particularly in overcoming blockages within vessels. A key issue is the foreign-body response (FBR) triggered by the implants, which impairs the integration between grafts and native vessels. In this study, we applied an interfacial infiltration strategy to create a stable, hydrophilic, and passivated hydrogel coating on SDVGs.

Aim: Foreign body ingestion, particularly that of magnets, is a significant issue for children aged 6 months to 3 years due to their prevalence in toys and household items. Most ingested foreign bodies pass naturally, but 10%-20% of such cases require endoscopic removal, and <1% require surgery.

Aim: Percutaneous vertebroplasty is generally considered a safe procedure, however, cases of cardioembolism and cardiac perforation have been reported.
Case Presentation: A 69-year-old woman was referred to our emergency department after an outpatient echocardiogram revealed a "thrombus-like" formation involving the right heart. Two weeks before she had undergone percutaneous vertebroplasty of the third to fifth lumbar vertebrae due to osteoporotic fractures.

This article examines the landscape of Science, Technology, and Innovation policies in Central America, focusing on Nicaragua, Guatemala, Honduras, and El Salvador. These nations face significant challenges in leveraging STI for sustainable development, including financial constraints and limited resources. Additionally, Central America struggles with systemic issues such as corruption, violence, and high levels of emigration, further complicating efforts to advance STI.
