Al CONCYTEC mis agradecimientos por la subvención económica entregada que fue un gran acicate para realizar oportunamente la tesis. Al CONCYTEC por creer en las pocas personas quienes viven haciendo un poco de ciencia con pocos recursos y con grandes vicisitudes, pero aún así son soñadores.

El propósito de la investigación fue determinar si la administración intramuscular en el glúteo de 4 mg Dexametasona antes y la administración intramuscular en el masetero de 4 mg de Dexametasona después de la extracción de terceras molares inferiores provocaba una mayor disminución de la inflamación frente a la administración intramuscular de 4 mg de Dexametasona antes de la cirugía, la administración intramuscular en el glúteo de 4 mg de Dexametasona en el masetero después de la cirugía y frente al grupo control. Para esto se administró la Dexametasona en 28 pacientes (16 mujeres y 12 varones) del departamento de Estomatología del Centro Médico Naval de la Marina de Guerra del Perú, con diagnóstico de terceras molares inferiores impactadas los cuales fueron divididos en 4 grupos: el grupo de administración intramuscular en el glúteo de 4 mg Dexametasona antes y ad...

El propósito de la investigación fue determinar la acción analgésica de ketorolaco en sapos espinales empleando el modelo experimental de dolor agudo en sumación temporal y espacial. La acción de analgésica de ketorolaco se evaluó por la cuantificación del reflejo de retirada de la pata y evaluación electromiográfica. La muestra fue conformada por 140 sapos que fueron seleccionados de acuerdo a los criterios de inclusión, divididos en: 1) 90 sapos para la validación del modelo experimental de dolor agudo; 2) 30 sapos para comparar la actividad del ketorolaco frente a memantina; 3) 20 sapos para evaluar la actividad electromiográfica del músculo semimembranoso. El análisis estadístico fue realizado empleando el software SPSS versión 14.0 para Windows. Se realizaron análisis descriptivos y pruebas estadísticas de significancia Kruskal Wallis y la prueba U de Mann Whitne...

Surgical antibiotic prophylaxis consists in the use of an antimicrobial drug in a preventive way, that must be active against microorganisms that in high frequency causes posterior infections of our surgical wounds and maintain effective tissue concentrations along the surgery procedure and the posterior time when appears the bacteremia. To reach a successful treatment is necessary to have the knowledge of the resident bactemial flora and the pathogenous flora that infects our surgical wounds. We must choose the correct antibiotic and use it by the correct time. Generally, that time does not exceed 24 hours and in the prophylactic schemes are used some antimicrobial drugs like beta-lactams, azalides lyncosamides and aminoglycosides, that must be selected depending of the medical condition of the patient and some topic related directly with the surgical technique employed.

The presence of adverse drug reactions with local anesthetics takes us to the search of effective alternatives to this drugs. 60 albino rabbits divided into 6 groups were submifted to infiltrative anesthetic technique in the maxilla with lidocaine, mepivacaine, bupivacaine, chlorpheniramine and dimenhidrinate, in front of sodium chloride 0,9%. The pain threshold belzavior was evaluated with electrical stimulation from Ruhnkorff s bobbin behind the drllg application and comparison between groups was made. The wlzite llsed drugs elevated the pain threshold, with a better response of lidocaine. Both local anesthetics and antihistamine drugs produced an effective local anesthesia, without tissue damage.

The aim of the study was to evaluate the possible modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours, in healthy young people, under therapy with two non steroidal anti inflammatory drugs (NSAID’s); one of them not selective to Ciclooxigenase (Ibuprofen) and a selective inhibitor of Ciclooxigenase - 2 (Celecoxib), during three days in standardized dose, in comparison with a control group that was administered placebo, in a double blind study. The results indicate that there are not statistically significant differences among the three groups, for the clinical and laboratory evaluated parameters (p <0,05). We conclude that a short term therapy with the used NSAID’s doesn’t produce clinical impact modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours.

The aim of this study was to compare two antibiotic prophylaxis regimens with Clindamycin in patients under semi-retained third lower molar surgery. Third molar extractions were carried out in healthy patients who complied with the inclusion criteria, in the central clinic surgery service of San Marcos University dentistry faculty. After having performed the exodontia control appointments were programmed during 5 days post – extraction where the infection signs were evaluated through the presence or bleeding or exudates on the surgical bed. This registration was carried out for both groups. The obtained data was analyzed using the Mann-Whitney U test (p <0.05). A significant difference was not found in the proportion of cases infected among the groups. However, the results showed a smaller quantity of patients with infection in the group of the intramuscular via (10%) in relation wi...
