Objectives: Desflurane may be useful for ambulatory anesthesia. However, desflurane-induced airway irritability makes its use challenging, especially in children. Ketamine can used to reduce separation anxiety and emergence agitation (EA). ketamine increase bronchial secretions. This study compared desflurane with sevoflurane anesthesia, terms of time EA, preschool children intravenous (IV) pre...

Poly(ethylene glycol) (PEG)-glycosaminoglycan (GAG) hydrogel networks are established as very versatile biomaterials. Herein, the synthetic gel component of biohybrid materials is systematically varied by combining different poly(2-alkyl-2-oxazolines) (POx) with heparin applying a Michael-type addition crosslinking scheme: POx gradated hydrophilicity and temperature-responsiveness provides poly...

DESCRIPTION A 12-year-old girl was referred to the emergency services with a history of consumption of pesticide chlorpyrifos (chlorpyrifos (0,0 diethyl l0 (3,5, tricholoro-2-pyridyl) phosphorothioate)), an organophosphorus compound, followed by multiple episodes of vomiting.
