Mechanical properties of basalt fiber reinforced composites manufactured with different vacuum assisted impregnation techniques
2016
Abstract This work describes an experimental mechanical characterisation campaign on composites made out of a quasi-unidirectional basalt fabric. In order to evaluate the ability of commercial basalt fabrics and their composites to meet the potentials of basalt fibers, the work has used raw materials from commercial catalogs with no further modification. Two common manufacturing techniques for medium performance composites have been adopted: vacuum assisted resin infusion, and hand-impregnated vacuum bagging. Two panels, one for each technique, have been fabricated, able to provide a sufficient number of samples for a comprehensive stiffness and strength characterization through Tensile, Fl…
Vacuum-Assisted Wound Closure with Mesh-Mediated Fascial Traction Achieves Better Outcomes than Vacuum-Assisted Wound Closure Alone: A Comparative St…
2017
Background Open abdomen (OA) permits the application of damage control surgery principles when abdominal trauma, sepsis, severe acute peritonitis and abdominal compartmental syndrome (ACS) occur. Methods Non-traumatic patients treated with OA between January 2010 and December 2015 were identified in a prospective database, and the data collected were retrospectively reviewed. Patients’ records were collected from charts and the surgical and intensive care unit (ICU) registries. The Acosta ‘‘modified’’ technique was used to achieve fascial closure in vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) patients. Sex, age, simplified acute physiology score II (SAPS II), ab…
Vacuum-Assisted Abdominal Closure in Surgical Emergency: A Single Institution Experience Treating a Cohort with a Prevalence of Faecal Peritonitis
2021
Abstract Vacuum-assisted abdominal closure (VAAC) has evolved as a promising method for treatment of emergent surgical patients. The aim of the study was an assessment of the complication rate and outcomes following routine application of VAAC in a cohort of patients suffering predominantly with peritonitis of the lower gastrointestinal tract (GIT) origin. The prospectively collected data was analysed retrospectively, including demographic data, aetiological factors, comorbid conditions and severity of the disease. The indications for VAAC included complicated intra-abdominal infection, purulent peritonitis with sepsis and/or risk of increased intra-abdominal pressure. In total, 130 patient…
Negatīvā spiediena terapijas ietekme uz organisma homeostāzi
2016
Literatūras norāda uz to, ka negatīvā spiediena brūču terapija sekmē ātrāku audu defekta dzīšanu. Šīs terapijas iespējamais blakusefekts var būt organisma proteīnu zudums. Vidējais kopējā proteīna līmenis eksudātā ir 57 g/L, bet albumīna līmenis ir 21 g/L. Terapija specifisks proteīna zudums var tikt aprēķināts reizinot seruma albumīnu ar 0.3. Literatūras datiem atbilstošu olbaltumvielu uzņemšanu, kas sastāda 1.5g/kg/dienā ir attiecīgi jāreizina ar 1.3, rezultātā iegūstot 2.0 g/kg/dienā. Oriģinālās savākšanas sistēmas tika pielietotas veiksmīgi, un laboratoriskie protokoli attiecībā pret eksudātiem tika paplašināti. Šis pētījums ir ieguldījums sarežģītā zinātnē par brūču dzīšanu, prasībām p…
