ABSTRACT
Objetivo: Evaluar la efectividad de la profilaxis analgésica con dosis únicas de clonixinato de lisina (CL 125mg) en pacientes sometidos a extracciones dentales. Metodología: Ensayo clínico aleatorio, doble enmascaramiento placebo-controlado. Participaron pacientes ASA I y II con indicación de exodoncia dental de servicios públicos en la ciudad de Valdivia-Chile en el mes de octubre del 2012. Se asignó de manera aleatoria dos grupos: un grupo tratamiento quienes recibieron una dosis de 25mg de CL 15 minutos antes de la cirugía; y un grupo control quien recibió un placebo. A ambos grupos se indicó CL como analgésico de rescate. Mediante un cuestionario, los pacientes registraron el grado de dolor a través de una Escala Visual Análoga (EVA) durante primer día en las 7 primeras horas, después de 24 y a las 48 horas posterior a la cirugía. Además, se registró número de cápsulas de CL consumidos como rescate durante 3 días posteriores a la intervención. Se comparó el efecto analgésico observado (EVA) y el número de consumo de analgésicos adicionales entre ambos grupos mediante t-test (p<0,05). Resultados: Cincuenta y cuatro pacientes fueron intervenidos. No se encontró diferencia estadísticamente significativa entre las puntuaciones de dolor entre ambos grupos. Los pacientes con profilaxis de CL informaron similar consumo de números de cápsulas de rescate que el grupo control. Conclusión: La profilaxis analgésica con CL no demostró ser más efectiva en la reducción del dolor luego de extracciones dentales en comparación al uso de placebo y dosis postquirúrgicas.
Aim: To evaluate the effectiveness of prophylaxis with single-dose analgesic clonixinate lysine (CL 125 mg) in patients undergoing tooth extraction. Methods: A double-blind randomized placebo-controlled trial. Were included in the study patients ASA I and II with dental extraction indication in the city of Valdivia, Chile in October 2012. Were randomly assigned in two groups: the treatment group received a doses of 125mg of CL fifteen minutes before the surgery, and a control group who received placebo. Both groups used a CL as a rescue analgesic. Using a survey, patients reported the degree of pain via a visual analog scale (VAS) during the first day, at 24 and 48 hours after surgery. In addition, registered the number of CL capsules consumed as a ransom for 3 days after the surgery. We compared the analgesic effect observed in (VAS) and the number of additional analgesic consumption between the two groups using t-test (p <0,05). Results: Fifty-four patients were operated and there was no statistically significant difference between the pain scores between the two groups. Premedication patients reported the use of equal number of rescue capsules comparing with the control group. Conclusion: CL analgesic prophylaxis proved no more effective in reducing pain after tooth extraction when comparing to the use of placebo in a postoperative doses.

Objective To explore the changes of etiology and mortality of upper gastrointestinal bleeding (UGIB) in the last 20 years in Guangdong region. Methods A total of 3140 UGIB cases diagnosed in Guangdong General Hospital from January 1990 to October 2009 were analyzed with retrospective analysis. Groups were divided according to admission chronological order and age to analyze the causes of UGIB to get the trend of changes and influencing factors. Results UGIB occurred more in men than in women, the gender ratio was 2. 5∶1. There was no significant change in gender composition between the first and later 10 years. Peptic ulcer bleeding (PUB) was the main cause of UGIB in young and middle-age patients (age0. 05) and esophagogastric variceal bleeding (EVB) (11. 7% vs 12. 9%, P>0.05) remained stable. The occurrence of AGML bleeding significantly increased than before (32. 4% vs 18. 8%,P<0. 01), and became one of the most important causes of UGIB. Conclusions PUB is still the most important cause of UGIB in Guangdong region. AGML becomes another important cause of UGIB in elder patients, which may relate to the increasing use of non-steroidal anti-inflammatory drugs (NSAIDs), anti-platelet and antineoplastic medicine.
