Observações sôbre a anestesia geral pelo hidrato de cloral na prática da cirurgia veterinária

In this paper the A. A. report the observations about the general anesthesia by chloral hydrate on the veterinary surgery. The observations were made on emasculation practices of horses, mules and hogs. It was possible to establish the following conclusions: 1) The choral hydrate presents low cost, it harmless, and is of easy application. 2) The more recommendable dosis for equine and swine were : 12-13 g per 100 k of body weight, in destilled water solution at 30 and 20%, respectively. 3) The anaethestic was injected by intravenous way with good results; in horses and mules the applications were made in the jugular; in swine, in the anterior vena cava, as was described by Carle and Dewhirst, because it was impracticable in the ear vein. 4) The dosis applied produced deep narcosis not lasting to long and with no danger to the animal's life. 5) In the case of fattening hogs, it must be made a discount of about 40% on the body weight, to calculate dosis to be employed. 6) The tables A and B show the results, that may be considered as good.

A regulação do lobo anterior da hypophyse por um hormonio testicular, especialmente sob o ponto de vista morphologico

The authors summarize the results of former works, based on the technics of parabiosis. After parabiotic union of two infantile rats, normal + castrate, the normal fellow enters into precocious puberty in about 7 days (Kallas). In the case of pairs: castrated male + normal female, the implants of testicles, or injection of maceration or aqueous extracts of testis in the castrated fellow, prevents the induction of early puberty in the normal female. In the case: castrated female + normal female, no inhibiting effect is provoked by that treatment. There is therefore a testicular hormone that regulates the hypophysis. After castration, this gland manifests a hyper-function and shows histological alterations, the chief character of these being the appearing in the anterior lobe, of the so-called castration cells, probably originated from basophile cells. Implants or injections of testis material prevent those alterations. This is a useful test; the effect is controlled by estimating the castration cells in the microscopic field. The testicular hormone that regulates the anterior lobe is probably another one, quite different from that which regulates the accessory genitalia. On account of the facts and experiments, it may be assumed that this new hormone is elaborated by the germinal epithelium of the testicles.

Implantação do mixoma infeccioso do coelho na câmara anterior do ôlho da cobaia

Mammalian cancer as well as the Rous chicken sarcoma has been successfully transplanted into the anterior chamber of the eyes of guinea pigs. It was of interest, therefore, to see if the infectious myxomatosis of rabbits, another representative of the infectious tumors, could be grown in the anterior chamber of the guinea pig eye, and, if growth occurred, to compare the tumor's behaviour with that of growths of the above mentioned etiology. Forty-three full-grown guinea pigs from mixed stocks were used throughout, and seventy-eight heterologous transplantation experiments were performed. The grafts measuring less than 2 mm. in diameter were cut from the subcutaneous tissue in skin lesions of rabbits with infectious myxomatosis recently killed. The transfer to the anterior chamber was performed after the usual technique. Some degree of partial survival was found in 23,8% of the grafts, in which typical myxoma cells could be demonstrated fifteen days after the transplantation. The transplant apparently does not increase in size, differing in that respect from that of the Rous chicken sarcoma, which increases in size by 2 or 3 diameters in 2 weeks (Shrigley, Greene & Duran-Reynals, 1945). The virus was still alive in 26% of the grafts 21 days after transplantation, and was able to induce a typical disease when injected to normal rabbits. No alteration in the properties of the virus after growth in the guinea pig was noticed, and this also is different from what happens with the Rous chicken sarcoma.

Transplantação de baço de coelho com mixoma infeccioso na câmara anterior do ôlho da cobaia: sôbre a degeneração mixomatosa: inclusões intranucleares

Heterotranplantability of myxoma of rabbits was formely demonstrated when grafts from subcutaneous tissue in skin were used (MARGARINOS TÔRRES & RITA CARDOSOS, 1949). Better results are reported in this paper when grafts from the spleen of infected rabbits were employed. While grafts from normal spleen are almost completely absorbed in sixteen days, those from infected rabbits give origin to full-grown and vascularised tissue in which typical myxoma cells are predominant elements. Progressive growth of heterotransplantated myxoma cells is another similarity between infectious myxoma and malignant tumors. Formation of clear areas of circular contour (interference of a diffusible substance?) associated to myxomatous degeneration is very conspicuous. Peculiar changes of the ground substance, reticular and collagenous fibers (globular swelling, rosary and bulb formation) apparently related to myxomatous degeneration are described. An unexpected finding was the presence of typical intranuclear inclusion bodies in five among forty-eight grafts examined in the sixth day.

A surgery for American cuteneous and visceral leishmaniasis among 1,342 dogs from areas in Rio de Janeiro (Brazil) where the human diseases occur

There are areas in the periphery of Rio de Janeiro city where human cases of Visceral and/or Cutaneous Leishmaniasis occur. The parasites have been identified as Leishmania donovani and Leishmania braziliensis braziliensis respectively. A survey for Leishmaniasis was done among 1,342 dogs from those areas using an indirect immunofluorescent test. From the dogs, 616 came from areas where only human cases of Visceral Leishmaniasis occurred, 373 from an area where all human cases were of Cutaneous Leishmaniasis and 353 from a third area (Campo Grande) where both visceral and cutaneous human cases were detected. The prevalence of parasite antibody titers among dogs from areas of Cutaneous Leishmaniasis was significantly higher than that of Visceral Leishmaniasis (8.6% vs. 4.3%, p < 0.02). The highest prevalence was observed among dogs from the area where both diseases are present (12.7%).

Hypothermia Prevention During Surgery: Comparison Between Thermal Mattress And Thermal Blanket


This study aimed to compare the efficiency of the thermal blanket and thermal mattress in the prevention of hypothermia during surgery. Thirty-eight randomized patients were divided into two groups (G1 – thermal blanket and G2 - thermal mattress). The variables studied were: length of surgery, length of stay in the post-anesthetic care unit, period without using the device after thermal induction, transport time from the operating room to post-anesthetic care unit, intraoperative fluid infusion, surgery size, anesthetic technique, age, body mass index, esophageal, axillary and operating room temperature. In G2, length of surgery and starch infusion longer was higher (both p=0.03), but no hypothermia occurred. During the surgical anesthetic procedure, the axillary temperature was higher at 120 minutes (p=0.04), and esophageal temperature was higher at 120 (p=0.002) and 180 minutes (p=0.03) and at the end of the procedure (p=0.002). The thermal mattress was more effective in preventing hypothermia during surgery.

Overweight And Obesity Repercussion In The Postoperative Of Myocardial Revascularization Surgery

This is a descriptive, retrospective study with cross-sectional quantitative approach, which aimed to relate the body mass index with events in the postoperative period of the myocardial revascularization surgery with use of extracorporeal circulation. The data collection period was between April and June/2012. Patients were divided according to the body mass index and classified as without excess of weight, overweight or obese. The data analysis was based on the descriptive statistics. The patients without excess of weight had more complications, especially those related to the lungs. Among overweight and obese individuals, the cardiovascular complications stood out. The obese subjects had the worse prognostic. Obesity and overweight did not have statistically significant association with a higher frequency of postoperative complications, in spite of the occurrence of cardiovascular complications in this group. The patients without excess of weight had higher risks of developing neurological events.


Therapeutic play in preparing for surgery: behavior of preschool children during the perioperative period

Objective:to describe the behavior of children during the instructional session of therapeutic play (ITP) in the preoperative period and to verify the behavior presented by them during the perioperative period. Methods: Exploratory descriptive study with a quantitative approach, developed in a large private hospital in Sao Paulo, in which the behaviors presented by 30 children between three and five years old, undergoing minor surgery were seen at the hospital during the session of TP and in the surgical center, from admission to awaken from anesthesia. Results: Most children participated in the ITP session (21; 70%), entered the surgical room spontaneously (22; 73.3%) without resisting mother separation (24; 80%), collaborating with the anesthetic procedure (16; 53.3%) and quietly awakening from anesthesia (26; 87%). Conclusion: The use of ITP led the child to understand the surgical procedure, making it less traumatic.


Perceived self-image in adolescent idiopathic scoliosis: an integrative review of the literature

Objective: To learn about the experiences of adolescents diagnosed with idiopathic scoliosis. Method: Integrative review of the literature published within a specified time frame. Results: For both sexes, the predominant clinical symptom of this condition appears to be the negative effect that the deformity exerts on perceived self-image. Quantitative studies used numerical scores to assess perceptions of body image but did not analyse emotional aspects. Patients treated surgically were found to have a better self-image than patients treated with a brace. Quality of life was improved by a reduction in the magnitude of the curve. Conclusion: Spinal deformity exerts a psychological effect on adolescent girls.


The decision of an obese woman to have bariatric surgery: the social phenomenology

Objective To understand the process by which an obese woman decides to have bariatric surgery. Method A qualitative survey with a social phenomenology approach, carried out in 2012, with 12 women, using the phenomenological interview. Results A woman bases the decision to have the surgery on: the inappropriateness of her eating habits; a physical appearance that is incompatible with an appearance that is standardized by society; the social prejudice that she has to live with; the limitations imposed by obesity; and her lack of success with previous attempts to lose weight. Outcomes that she hopes for from the decision to have the surgery include: restoring her health; achieving social inclusion; and entering the labor market. Conclusion This study allows one to reflect that prescriptive actions do not give a satisfactory response to a complexity of the subjective questions involved in the decision to have surgery for obesity. For this, what is called for is a program of work based on an interdisciplinary approach, and training that gives value to the bio-psycho-social aspects involved in a decision in favor of surgical treatment.

Predictors of red blood cell transfusion after cardiac surgery: a prospective cohort study

Abstract OBJECTIVE To identify predictors of red blood cell transfusion (RBCT) after cardiac surgery. METHOD A prospective cohort study performed with 323 adults after cardiac surgery, from April to December of 2013. A data collection instrument was constructed by the researchers containing factors associated with excessive bleeding after cardiac surgery, as found in the literature, for investigation in the immediate postoperative period. The relationship between risk factors and the outcome was assessed by univariate analysis and logistic regression. RESULTS The factors associated with RBCT in the immediate postoperative period included lower height and weight, decreased platelet count, lower hemoglobin level, higher prevalence of platelet count <150x10 3/mm3, lower volume of protamine, longer duration of anesthesia, higher prevalence of intraoperative RBCT, lower body temperature, higher heart rate and higher positive end-expiratory pressure. The independent predictor was weight <66.5Kg. CONCLUSION Factors associated with RBCT in the immediate postoperative period of cardiac surgery were found. The independent predictor was weight.

Influência da cultura anterior e da compactação do solo na absorção de macronutrientes em soja

O objetivo deste trabalho foi avaliar a concentração e a absorção de macronutrientes em soja cultivada em subseqüência a sete espécies vegetais em solo com diferentes níveis de compactação. O experimento foi conduzido em vasos contendo amostras de um Latossolo Vermelho, textura franco-arenosa, com camada de 3,5 cm compactada até as densidades de 1,12, 1,36 e 1,60 Mg m³, em que se cultivou anteriormente aveia-preta, guandu, milheto, mucuna-preta, soja, sorgo granífero, tremoço azul, mantendo-se um tratamento sem planta (pousio). Essas espécies se desenvolveram por 37 a 39 dias, foram cortadas ao nível do solo, picadas em partículas de, aproximadamente, 3 cm, e deixadas sobre a superfície do vaso por 40 dias. As plantas foram colhidas 28 dias após a emergência. Avaliou-se a produção de matéria seca, concentração e acúmulo de macronutrientes na parte aérea das plantas. A compactação do solo em subsuperfície diminui a nutrição da soja. A nutrição da soja é beneficiada quando cultivada em sucessão a plantas de cobertura no solo. O pousio antecedendo a cultura da soja não é recomendado como meio de reduzir os efeitos da compactação do solo.
