[Risk Analysis and Study of Post-marketing Adverse Events for Absorbable Sutures].

To investigate, analyze, and evaluate the risk data associated with the clinical use of absorbable sutures by retrieving and summarizing information from the databases of the US FDA and CNKI, as well as the adverse event reports related to absorbable sutures from January 2019 to October 2022 within Zhejiang province. The adverse event reports are obtained from both incident locations and monitoring organizations affiliated with the registrant. The aim is to identify the main risk factors associated with the clinical use of absorbable sutures.

High-Antimicrobial Gallium-Doped Zinc Oxide Thin Films on Bio-Based Poly(Ethylene Furanoate) Substrates for Food Packaging Application.

Thin films of gallium-doped zinc oxide (GZO), with a thickness of around fifty nanometers were deposited on bio-based poly(ethylene furanoate) (PEF) substrates by radio-frequency sputtering. By optimizing the Ga concentration in the target, the optics, water vapor barrier and antibacterial properties of PEF/GZO composite films can be adjusted. The highest visible light transmittance of the samples was around 85.

[Study of Adverse Events of Endotracheal Intubation].

Objective: In order to further decrease and reduce the serious adverse events of silicone rubber endotracheal intubation in clinical use, especially in anesthesia and intensive care.

Methods: Through the first stage analysis on the registration and certification of endotracheal intubation products in China, adverse events of products in recent five years in Zhejiang province, domestic and foreign literature of adverse events of products, retrieval of product citation standards, content integrity of product instructions, and expert seminar on serious adverse events, combined with the air leakage of endotracheal intubation products in recent two years, product material and clinical application with normative aspects.

Results: Silicone rubber endotracheal intubation products in clinical intensive care have certain clinical safety risks, especially for long-term use of critically ill patients.

[Study on Adverse Events of Infant Incubator Products].

Objective: To investigate the risk of adverse events in the clinical use of infant incubators of three kinds of national medical devices in Zhejiang Province.

Methods: Semi-quantitative matrix analysis was used to analyze the risk of adverse events related to incubator products in Zhejiang province from August 2018 to August 2019.

Results: Through the risk analysis of 213 cases of adverse events of infant incubator product, the risk point and degree of the product in practical clinical application were evaluated.
