According to Anvisa risk rating, hypodermic needles offer medium risk to the user’s health. This study discussed the importance of the corrosion resistance test in tubes of hypodermic needles, in the product quality control. A review of cannulas of hypodermic needles was carried out according to ISO 9626:2003 and 9259:1997 ABNT NBR. For the results evaluation, a scale which classifies the extent of corrosion was adjusted. 174 samples of PNI needles from 17 States and 9 different record holders were analyzed. According to the methodology of ISO 9626:2003, 100% of the samples were considered satisfactory. However, in accordance with the methodology of ISO 9259:1997, 97.1% of the samples were rejected. Irregularities can lead to impairment of product quality, resulting in risks to the consumer’s health. Since 2011 the product has undergone certification, so it is necessary to reflect on the importance of corrosion resistance testing and mandatory certification for health monitoring.

RESUMO A certificação metrológica é uma importante ferramenta de Vigilância Sanitária. O objetivo deste estudo foi avaliar o perfil das notificações de queixas técnicas de seringas hipodérmicas realizadas no Notivisa/Anvisa (Sistema Nacional de Notificações de Eventos Adversos e Queixas Técnicas/Agência Nacional de Vigilância Sanitária) entre 2012 e 2015. As notificações foram analisadas individualmente e classificadas conforme os motivos relatados. Foram avaliadas 4181 notificações, e as queixas mais prevalentes foram: 'produto quebrado na embalagem lacrada' (22%) e 'sujidade/manchas no interior do produto/embalagem' (15,8%). Não foram observadas alterações significativas no perfil das queixas após a certificação compulsória, que, embora imprescindível, não é capaz de substituir o monitoramento pós-comercialização.

ABSTRACT Metrological certification is an important Sanitary Surveillance tool. The objective of this study was to evaluate the profile of notifications of technical complaints of hypodermic syringes performed in Notivisa/Anvisa (Sistema Nacional de Notificações de Eventos Adversos e Queixas Técnicas/Agência Nacional de Vigilância Sanitária) between 2012 and 2015. The notifications were analyzed individually and classified according to the reasons reported. 4181 notifications were evaluated and the most prevalent complaints were: 'broken product in the sealed package' (22%) and 'dirt/stains inside the product/packaging' (15.8%). There were no significant changes in the profile of the complaints after compulsory certification, which, although indispensable, is not capable of replacing post-marketing monitoring.

Aim: The objective of this study was to critically analyze data of the National Notification System for Adverse Events and Technical Complaints (Notivisa) related to central venous catheters, through an evaluation of the description of notifications recorded between 2006 and 2009. Methods: Notifications were categorized and evaluated to: (i) determine the number of adverse events and technical complaints, (ii) verify compliance with the classification criteria defined by the legislation, (iii) reclassify notifications, when necessary, in order for them to fit in with the legal definitions, (iv) verify registered companies in Brazil, (v) quantify the notifications according to the registered company and product lot, and (vi) identify the country of original of the notified product. Microsoft Excel® 2010 was used to categorize and systematize the data. Results: Some conceptual errors and incomplete records were found. Altogether, 228 notifications of technical complaints and 119 of adverse events were identified. Some notifications on guidewires and broken catheters were reported which led to the necessity of duplicating some medical procedures and to the occurrence of lesions/lacerations of vessels and tissue injury. Forty-seven percent of companies presented at least one notification in Notivisa and in all, 38 product lots had more than one notification. Conclusion: These data support a necessity for cooperation between all entities of the National Health Surveillance System to check compliance of this type of product and to properly report adverse events and technical complaints. It is also important to incorporate minimum standards for the management of technologies in health services, including in the acquisition of products and training of staff.
