Abstract: context: studies in the area of health economics are still poorly explored and it is known that the cost savings in this area is becoming more necessary, provided that strict criteria. objective: to perform a cost-effectiveness analysis of spinal anesthesia versus local anesthesia plus sedation for loop colostomy closure. methods: this was a randomized clinical trial with 50 patients undergoing loop colostomy closure either under spinal anesthesia (n = 25) or under local anesthesia plus sedation (n = 25). the duration of the operation, time spent in the post-anesthesia recovery room, pain, postoperative complications, length of hospital stay, laboratory and imaging examinations and need for rehospitalization and reoperation were analyzed. the direct medical costs were analyzed. a decision tree model was constructed. the outcome measures were mean cost and cost per local and systemic postoperative complications avoided. incremental cost-effectiveness ratios were presented. results: duration of operation: 146 ± 111.5 min. vs 105 ± 23.6 min. (p = 0.012); mean time spent in post-anesthesia recovery room: 145 ± 110.8 min. vs 36.8 ± 34.6 min. (p<0.001). immediate postoperative pain was lower with local anesthesia plus sedation (p<0.05). local and systemic complications were fewer with local anesthesia plus sedation (p = 0.209). hospitalization + rehospitalization: 4.5 ± 4.1 days vs 2.9 ± 2.2 days (p<0.0001); mean spending per patient: r$ 5,038.05 vs 2,665.57 (p<0.001). incremental cost-effectiveness ratio: r$ -474.78, indicating that the strategy with local anesthesia plus sedation is cost saving. conclusion: in the present investigation, loop colostomy closure under local anesthesia plus sedation was effective and appeared to be a dominant strategy, compared with the same surgical procedure under spinal anesthesia.

Abstract: context: recent studies have shown that local anesthesia for loop colostomy closure is as safe as spinal anesthesia for this procedure. objectives: randomized clinical trial to compare the results from these two techniques. methods: fifty patients were randomized for loop colostomy closure using spinal anesthesia (n = 25) and using local anesthesia (n = 25). preoperatively, the bowel was evaluated by means of colonoscopy, and bowel preparation was performed with 10% oral mannitol solution and physiological saline solution for lavage through the distal colostomy orifice. all patients were given prophylactic antibiotics (cefoxitin). pain, analgesia, reestablishment of peristaltism or peristalsis, diet reintroduction, length of hospitalization and rehospitalization were analyzed postoperatively. results: surgery duration and local complications were greater in the spinal anesthesia group. conversion to general anesthesia occurred only with spinal anesthesia. there was no difference in intraoperative pain between the groups, but postoperative pain, reestablishment of peristaltism or peristalsis, diet reintroduction and length of hospitalization were lower with local anesthesia. conclusions: local anesthesia plus sedation offers a safer and more effective method than spinal anesthesia for loop colostomy closure.

Arquivos de Gastroenterologia , 2007, DOI: 10.1590/S0004-28032007000100007
Abstract: background: pancreatic pseudocysts are relatively common complications of pancreatitis in adults. objective: to evaluate the long-term results from transmural endoscopic drainage and thus to establish its role in managing pancreatic pseudocyst. methods: fourteen patients with pancreatic pseudocyst were studied. their main complaint was pain in the upper levels of the abdomen. they presented palpable abdominal mass and underwent cystogastrostomy (n = 12) and cystoduodenostomy (n = 2), with clinical follow-up using abdominal computed tomography for up to 51 months. retrograde endoscopic cholangiopancreatography was attempted in all cases to study the pancreatic duct and classify the cysts. results: there were 10 cases (71.5%) of chronic pancreatitis that had become acute through alcohol abuse and 4 (28.5%) that had become acute through biliary disorders. both types of endoscopic drainage (cystogastrostomy and cystoduodenostomy) were effective. there was no change in the therapeutic management proposed. migration of the orthesis into the pseudocyst at the time of insertion (two cases) was the principal complication, and these could be removed during the same operation, by means of a dormia basket, with the aid of fluoroscopy. there has so far not been any mortality or relapse. the mean hospital stay was 3 days. conclusion: transmural endoscopic drainage was an efficacious form of therapy, presenting a low complication rate and no mortality, and only requiring a short stay in hospital.

Análisis de las películas pasivas generadas en aceros inoxidables implantados con cromo
Abreu, C. Ma,Cristóbal, J.,Nóvoa, X. R.,Pena, G.
Revista de Metalurgia , 2004,
Abstract: This work studies the effect of chromium implantation on the development of passive layers generated electrochemically in alkaline medium over two stainless steels. The XPS analyses show that the layers generated on the implanted steels present less thickness together with similar composition compared to the unimplanted steels layers. However, SEM micrographs show that the layers grown on implanted steels present more defects and less adherence that the films on unimplanted steels. These changes together with the results obtained by Cyclic Voltammetry suggest an oxide structure modification, lattice structure or cristalinity state. En este trabajo se estudia el efecto de la implantación de cromo en el desarrollo de capas pasivas generadas electroquímicamente en medio básico sobre dos aceros inoxidables (AISI 430 y AISI 304L). Los análisis de XPS muestran que las películas desarrolladas sobre ambos aceros implantados presentan espesores menores, junto con composiciones similares, a las formadas sobre los no implantados. Sin embargo, en los resultados del examen con MEB se puede apreciar que las películas tienen más defectos (agrietamientos) y peor adherencia (especialmente en el AISI 430). Este cambio, junto con los datos de voltametría cíclica, parece sugerir una modificación en la estructura de los óxidos, bien en su grado de cristalinidad o bien en la estructura de su red cristalina.

Abstract: Chemical treatment in solutions containing cerium compounds has been widely used for prevention of localized corrosion in aluminium alloys (pitting corrosion) as well as in stainless steels (crevice corrosion). Ionic implantation presents several advantages for stainless steels. The present paper is devoted to study the effect of cerium implantation on the properties of passive films formed on an AISI 430 stainless steel in alkaline medium. The electrochemical study is performed by cyclic voltammetry and EIS. The chemical characterisation of the oxides film developed is performed by XPS, and the morphological study corresponds to SEM examination. The results show that cerium implantation hinders magnetite formation as well as chromium oxidation processes. En los últimos a os, se ha extendido el uso de disoluciones de sales de cerio como tratamiento para mejorar la resistencia localizada de las aleaciones de aluminio y para incrementar la resistencia a la corrosión en resquicio de diversos aceros inoxidables. En el caso de estos últimos, la adición de cerio mediante implantación iónica supone notables ventajas con respecto a otros tratamientos. En este artículo se investiga el efecto que ejerce la implantación de cerio sobre la película pasivante de un acero inoxidable ferrítico AISI 430. Para ello, se analiza el comportamiento electroquímico en medio básico mediante la utilización de voltametría cíclica y espectroscopia de impedancia electroquímica. La caracterización química de la película de óxidos formada se realiza mediante XPS, y el estudio morfológico mediante SEM. Los resultados muestran una importante inhibición en la formación de magnetita, así como una reducción en el proceso de oxidación que experimenta el cromo en el acero implantado con cerio.
