Effectiveness of Glycerin Magnesium Sulphate Versus Heparin Benzyl Nicotinate Application Among Children with Phlebitis

Introduction: Phlebitis is the most common complication of intravenous infusion therapy. Incidence of phlebitis in children receiving intravenous therapy has been reported to be as high as 71.25%. The study was done to find out the effectiveness of glycerin magnesium sulphate versus heparin benzyl nicotinate application in children with phlebitis. Methods: A pre-post control group design was used. A total of 43 subjects were randomly assigned into two groups [22 in experimental (glycerin magnesium sulphate application) and 21 in control (heparin benzyl nicotinate application) group] by lottery method. Data was collected using Modified Visual Infusion Phlebitis (VIP) Score. Results: The comparison between VIP score was based on observations made before the interventions and at 12, 24, 36 and 48 hours after the intervention. Independent t tests showed significant difference in reduction of VIP score in experimental and control group after 12 hours and 24 hours of intervention. The study demonstrated that there is no statistically significant difference in reduction of VIP score among the subjects in experimental and control group at 12 hours (p = 0.219), 24 hours (p = 0.349), 36 hours (p = 0.695) and 48 hours (p = 0.424) after the intervention. Conclusion: The study concludes that both glycerin magnesium sulphate and heparin benzyl nicotinate can be used effectively among children with phlebitis. However, after 24 hours of phlebitis, an alternative intervention needs to be used.

Systematic Design of Crystal Structure for Hofmann-Like Spin Crossover Fe(L)2[Ag(CN)2]2 Complexes

The synthesis, crystal structures, and magnetic properties of a new two-dimensional (2D) Hofmann-like series, FeII(L)2[AgI(CN)2]2 (L = 3-cyano-4-methylpyridine (1), allyl isonicotinate (2), phenyl-isonicotinate (3), and benzyl nicotinate (4)) were studied. These compounds have a 2D sheet structure because of their strongly determinate self-assembly process. An octahedral FeII ion is coordinated with the nitrogen atoms of[AgI(CN)2 linear units at equatorial positions and monodentate pyridine derivatives at the axial position. The layers construct a parallel stacking array. Compounds 1–3 show pairs of layers constructed by intermetallic Ag···Ag interactions. Compound 4 shows a mono-layer structure. The substituent bulk of the ligands affects the interlayer space. Compounds 1–4 undergo a 100% spin transition. However, compound 1, incorporating a smaller group, has a relatively lower critical temperature (Tc = 182 K (1), Tc = 221 K (2), Tc = 227 (3) and Tc1 = 236 K, Tc2 = 215 K (4)). We investigated the correlations between our systematic crystal design, substituent size, and the spin crossover profiles.
