Evaluation of silver content and antibacterial activities of silver loaded fiber/cotton blended textile fabrics

The aims of this work were to analyze the antibacterial activity and laundering durability of the silver loaded cellulosic fiber/cotton blended antibacterial textile fabrics, to quantify the silver content present in fabrics, and to examine the relationship between the antibacterial activity and silver content. For this aims knitting fabrics consisting of SeaCell® Active, which is the cellulosic fiber incorporated with seaweed and silver ions, and cotton fibers blended with five different ratios were produced. All fabric samples bleached and washed 60 times. The antibacterial efficiency was evaluated according to AATCC 100-1999 method after each ten laundry cycles. Silver content of the fabrics were determined by atomic absorption spectroscopy (AAS). Fiber and fabric surfaces were investigated using Scanning Electron Microscopy (SEM) and by X-Ray Photoelectron Spectroscopy (XPS) views. Antibacterial tests showed that good antibacterial activity can be achieved after several washings even with 3% of SeaCell ® Active fibers in blended fabrics. Significant correlation was found between silver content and bacterial reduction

Combined spinal-epidural anesthesia or local anesthesia + Sedoanalgesia in abdominal aortic Aneurism Repair?

Objective: Anesthesia for the repair of abdominal aortic aneurism can be performed with different modalities of anesthesia or their combinations. The risk level for the morbidity and mortality of the patients, is increased in geriatric patients with the existence of accompanying pathology. To compare two different anesthesia methods (local anesthesia and sedation vs combined spinal and epidural anesthesia) for the repair of endovascular aneurism in a geriatric patient. Material and Methods: 16 high risk geriatric patients were included in the study. The parameters of 16 high risk patients who underwent elective or emergency treatment for endovascular aneurism were included. Group-I (n:8) was given local anesthesia and sedation, Group-II (n:8) was given combined spinal and epidural anesthesia. Intraoperative and postoperative hemodynamic parameters were reviewed and analyzed. The demographic data of the two groups ressembled each other. Results: The complication rate was calculated at an average of 6.25%, which was considered insignifcant (p>0.05). There was no signifcant difference between the duration of hospital and intensive care unit stay for the two groups (p>0.05). Conclusion: Combined spinal and epidural anesthesia requires much more experience, but it is safer than local anesthesia and sedation for endovascular aneurism patients
