New microvascular anastomotic device for end-to-side anastomosis using negative pressure; a preliminary study. J Plast Surg Hand Surg. 2020 Feb 24;:1-5 Authors: Tachi K, Furukawa KS, Koshima I, Ushida T Abstract We previously developed a device for end-to-end anastomosis powered by negative pressure and demonstrated that using the device allow the operator to anastomose semi-automatically with little stress. Here, we sought to build a device for and demonstrate that negative pressure can also be used in end-to-side anastomosis which is clinically popular as end-to-end anastomosis through animal experiment using rats.The devices were constructed with a laser lithographic/3D-printing machine. Nine SD rats were used. Each of the nine rats underwent end-to-side anastomosis between the superficial epigastric vein and the femoral vein using the device. Rat was anesthetized one week later and the anastomotic site was inspected through operative microscope for patency. The anastomotic site was harvested with the device and the rat was euthanized. The anastomotic site was embedded in epon, sectioned, stained with toluidine blue, and analyzed with light microscopy. Eight of the nine anastomoses were patent immediately after the procedures, and two of the nine were patent at 1 week after the procedures. In the failed cases, the vessels dislocated from the device because the clamps loosened during the observation period after the operation. The experiments hav...
In this study, an attempt to oxidise the surface of a commercial activated carbon to improve its adsorption capacity for sevoflurane was conducted using 6 mol/L nitric acid, 2 mol/L ammonium persulfate, and 30 wt per cent (wt%) of hydrogen peroxide (H2O2). The adsorption tests at fixed conditions (bed depth: 10 cm, inlet concentration: 528 mg/L, and flow rate: 3 L/min) revealed that H2O2 oxidation gave desirable sevoflurane adsorption (0.510 ± 0.005 mg/m2). A parametric study was conducted with H2O2 to investigate the effect of oxidation conditions to the changes in surfa...
ConclusionAS/AD is a mechanical disorder of the larynx that can be successfully treated if promptly diagnosed. Clinical trials and multi-centric studies are necessary to set management guidelines.
