- ItemAcesso aberto (Open Access)Aplicability of respiratory muscle strength as part of the surgical risk scale based on Tonrrington and Henderson scoring system(Pontifícia Universidade Católica do Paraná, 2014-03-01) Freitas, Eliane Regina Ferreira Sernache De; Leoni, Aline Maria Tonin; Universidade Federal de São Paulo (UNIFESP); University of Northern Paraná; Irmandade da Santa Casa de Londrina; University of Northern Paraná Hospital Physiotherapy; Hospital Zona SulObjectiveEvaluate the applicability of mean percentage from the predicted value of respiratory muscle strength (maximal inspiratory pressure-MIP; maximal expiratory pressure-MEP), as (% MIP + % MEP)/2, as well as the peak expiratory flow (% PEF) preoperatively, as part of a surgical risk scale for predicting the risk of postoperative pulmonary complications (PPC). MethodData on patients undergoing elective surgery of chest, abdomen and limbs were assessed preoperatively using the items and the scoring system proposed by the Torrington and Henderson, and replacing spirometry by the mean values of both (% MIP + % MEP)/2 and % PEF. ResultThe proposed scale applied to 108 patients with a mean age of 55.2 ± 14.0 presented PPC rate of 37.0% (p = 0.0001), of which 20.0% were classified as high risk (HR), and 62.5% moderate risk (MR). The mean value of respiratory muscle strength showed a statistically significant correlation with PPC (p = 0.000). ConclusionThe proposed scale allowed the appropriate stratification of patients at risk for development of PPC. The use of the mean values of (% MIP + % MEP)/2 and % PEF based on the predicted values can be easily applied, making spirometry unnecessary.
- ItemAcesso aberto (Open Access)Hypertonic glucose solution 10% - 25% on the mesenterium and peritoneum of the rat: macroscopic and microscopic study(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2005-12-01) Carvalho, José Cícero Ferreira De; Leal, Antenor Teixeira; Sousa, Luis Ferreira De; Herani Filho, Benedito [UNIFESP]; UNCISAL Department; UFAL Morphology Department and Human Anatomy; Universidade Federal de São Paulo (UNIFESP)PURPOSE: The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat. METHODS: 90 Wistar females young rats adults were used weighin between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0,9% saline solution was used called control group, or group A, 10% glucose solution named group B, and in the others 30 was used 25% glucose solution named group C, differing in the observation period, (06h, 24h and 48h), but with the same procedure. A midline abdominal wall laparotomy was made and in the animals of the control group was injected 2 ml of a 0,9% saline solution into the peritoneal cavity. After, we made a suture in mass without to include the peritoneum. For the others groups (B, C) the rats received 10% glucose solution and 25% glucose solution injected into the peritoneal cavity respectively. All groups were kept under observation and the results were submitted to statistical analysis by a longitudinal and transversal comparative study. RESULTS: A new surgery was done in 6h, 24h and 48h, and we observed in macroscopic evaluation, the presence of fluid, serous uniforme and rosy all over the cavity. Vascular congestion was present. We dried out 90 fragments of mesenterium and 90 fragments of parietal peritonium bilateral. In the microscopic study, necrosis was not present. For the mesenterium histological study we observed 16 cases (17,8%) unspecific chronic inflammation, 30 cases (33,4%) hiperplasic linfonod, 10 cases (11,1%) high vascular congestion, 6 cases (6,6%) reaction fibrosis and 28 cases (31,1%) no alteration. For the parietal peritonium histological study we observed 6 cases (3,3%) reaction fibrosis and 174 cases (96,7%) no alteration. Giant cell was not present. In the statistical analisys statistic there is no significance between the groups (p>0,05). CONCLUSION: Hypertonic glucose solution and NaCl 0,9% on the mesenterium and parietal peritonium do not produce tissue necrosis in a rat and the inflammation process has the same intensity.
