Concerning one case of rupture of a flow regulator: How patient safety procedures contribute to the correct use of medical devices.

Flow regulators are widely used in hospitals to assist with intravenous (IV) infusion of medication. The rupture of a flow regulator at the base of the clamp was observed during parenteral nutrition. This rupture resulted in fluid leakage and an inlet of air, responsible for an air embolism in a fragile patient who had undergone a bilateral lung transplant.

[Occurrence of delayed symptoms after a challenge test with methacholine].

There are few prospective studies available on the development of delayed symptoms following challenge tests with methacholine (MCT) at the currently recommended doses. The objective of this study was to describe the nature and frequency of respiratory symptoms suggestive of bronchospasm developing within 24hours after a MCT. The study was offered to adult patients who underwent MCT seen consecutively between June and October 2015.

[Imprecision of vancomycin prepared for intravenous administration at the bedside in a neonatal intensive care unit].

In pediatric units, most of the intravenous medications are prepared by the attending nurse at the bedside that can be affected by an error margin, so can be imprecise. Despite the possible consequences of imprecise medications administration, published studies on the topic are scarce. The main objective of this study was to measure the difference between the prescribed vancomycine concentration and the actual concentration measured in the medication administered to the patient.

Hospital morphine preparation for abstinence syndrome in newborns exposed to buprenorphine or methadone.

Objective: This study was undertaken to evaluate the adequacy of a hospital formulated oral morphine preparation for management of neonatal abstinence syndrome (NAS) and to compare clinical features in infants exposed to methadone or buprenorphine in utero.

Method: Between October 1998 and October 2004 all infants born to mothers treated with buprenorphine or methadone during pregnancy were enrolled into this prospective study. Morphine hydrochloride solution (0.
