Effect of inhaled waste anaesthetic gas on blood and liver parameters among hospital staff

A significant health risk exists within a section of health workers that are exposed to anaesthetic gas and vapours, found in the atmosphere of treatment or operating rooms. These compounds are classified as waste anaesthetic gases (WAG). The present study aimed at identifying alterations in hepatic and haematological parameters occurring as a result of chronic exposure to WAG potentially affecting the health of team members working in hospitals. Therefore, operating room operatives, vulnerable to long-standing WAG exposure, were recruited for this study. Sevoflurane anaesthesia metabolites (inorganic fluoride and hexafluoroisopropanol (HFIP)), haematological indices and liver toxicity markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase and osteopontin) were measured. The collected results showed increased plasma inorganic fluoride, HFIP and liver toxicity markers, as well as disturbances in haematological parameters. In conclusion, exposure to halogenated inhalational anaesthetics, in general, and Sevoflurane, in particular, induces alterations in hepatic markers and haematological indices.

Protactinium(V) in aqueous solution: a light actinide without actinyl moiety

This review highlights recent data on the complexation of Pa(V) with inorganic (fluoride and sulphate) and organic (oxalate, nitrilotriacetate, diethylenetriaminepentaacetate) ligands in solution. New thermodynamic parameters relative to the complexation of Pa(V) with sulphate are presented. The review also includes gas phase and theoretical studies focused on the interaction of Pa(V) in the dioxo and oxo forms with water.

Fluorescent triazolium for sensing fluoride anions in semi-aqueous solution

A new triazolium-based receptor for fluorescent sensing of inorganic fluoride anions in semi-aqueous solution and the solid state was reported.
