Avaliação nutricional pré-operatória dos pacientes com megaesôfago não-avançado / Pre- operatory nutritional evaluation of patients with non-advanced megaesophagus

OBJETIVO: Avaliar o estado nutricional de pacientes com megaesôfago não-avançado no pré-operatório. MÉTODO: Foram selecionados dez pacientes adultos (seis do sexo masculino, quatro do feminino) provenientes dos Ambulatórios de Cirurgia do Hospital Regional do Vale do Paraíba-SAB e do Hospital Universitário de Taubaté. O diagnóstico do megaesôfago foi realizado por meio de um protocolo com informações referentes à origem epidemiológica, quadro clínico, sorologia para doença de Chagas, esofagrafia, endoscopia digestiva alta e eletromanometria. A avaliação do estado nutricional foi feita com dados antropométricos (Peso, IMC, CB, PCT e CMB) e bioquímicos (albumina, transferrina e linfocitometria). RESULTADOS: O peso foi o parâmetro mais comprometido, sendo a porcentagem de perda de peso considerada grave em oito pacientes. Somente um paciente classificou-se como percentil 5. Não houve alteração bioquímica significante. CONCLUSÃO: A maioria dos pacientes é eutrófica, sendo um paciente considerado desnutrido.

BACKGROUND: Evaluating the nutritional condition of patients with not advanced esophagus preoperatively. METHODS: Ten adult patients were selected (6 male and 4 female) from Surgery Ambulatories of a public regional Hospital in Vale do Paraiba and of University Hospital of Taubaté. The mega esophagus diagnosis was made based on a guidance with information concerning to the epidemiological origin, clinical status, Chagas disease evidence and exams such as contrasted esophagogram, upper digestive endoscopies and electromanometry. The evaluation of the nutritional condition was made with anthropometric data (weight, Body Mass Index, Arm Circumference, and Arm muscular circumference) and biochemicals (transferrine albumin and lymphocitometer). RESULTS: The weight was the most affected parameter, and the percentage of weight loss was considered severe in eight patients. Only one patient was classified with a percentage of 5. There was no significant biochemical change. CONCLUSION: Most of the patients are eutrophic, and one patient is considered undernourished.

Apendicite aguda. Modelo experimental em coelhos / Acute apendicitis. model experimental in rabbits

The evolving phases of acute appendicitis were studied experimentally. Sixty female rabbits (Oryctogalus cuniculus) of New Zealand lineage weighing about 2510 to 3040 g were divided in two groups: a control group and experimental group. The experimental group was divided into three subgroups for observation after 12, 24 and 48 hours of the operation, that consisted on a 4-0 polypropylene circular suture at 8 cmfrom the distal part of the cecal appendix. The control group was sham operated. The macroscopic exam (increase of the appendix volume, necrosis, perfuration, adherence and secretion in the abdominal cavity)...

Modelo de dispositivo para treinamento e avaliaçäo das habilidades em técnica operatória / Device model for training and evaluation on the abilities in operative technique

Com o objetivo de facilitar o aprendizado da técnica operatória, em especial na realizaçäo de nós e suturas cirúrgicas, foi desenvolvido um modelo experimental näo biológico, contendo dispositivos simples que simulam diversas situaçöes encontradas no procedimento cirúrgico fundamental.
