    Correlación de la medición directa de la presión intraabdominal y la presión programada de insuflación de CO<sub>2</sub> en cirugía laparoscópica
    (2017) Liliana Silva Sánchez; Diana Leticia Rodríguez Zamorano; Fernando Elizalde Flores; Mario Enrique Rendón Macías
    Introduction: An intraabdominal pressure less than 14 mmHg is fundamental to avoid hemodynamic alterations during laparoscopic procedures. The monitoring by insuffl ation pressure (InfP) may not be the most reliable. Objective: To compare the InfP values with those measured directly in the abdominal cavity (IAP), and to establish their correlation with hemodynamic variations. Material and methods: During eight laparoscopic procedures, we obtained InfP and IAP measures simultaneously: at baseline and every fi ve minutes until the suspension of the pneumoperitoneum. All procedures were under general anesthesia and deep and/or intense neuromuscular blockage. We analyzed the hemodynamic stability (heart rate, arterial pressure and peripheral oxygen saturation) with the InfP and IAP measures. Results: We analyzed 54 pair measures. The correlation between measures was 0.86 (p < 0.001, R 2 = 0.74). Fifteen measures (27.8%) were equal; in 59.3% IAP > InfP, and in 14.1% IAP < InfP. The variations of IAP 14 mmHg were associated with arterial hypertension and tachycardia, while IAP 11 mmHg were associated with low diastolic arterial pressures and low heart rate (< 60). Conclusions: The monitoring of the intra-abdominal pressure with InfP may not be reliable, so we recommend a direct measurement.

    Disminución del consumo de opioides con el uso de dexmedetomidina durante el periodo transanestésico
    (2021) Tania Gabriela Martínez Álvarez; Fernando Elizalde Flores; Magali Delgado Carlo; Lizbeth Cañas Lucero; José L Limón Aguilar; María Elena Pinto Segura
    Introduccin: Recientemente los objetivos de la cirugia mayor tratan de enfocarse en ofrecer las mejores posibilidades para una pronta recuperacion y reanudacion a las labores cotidianas con adecuada calidad analgesica, cuestiones que representan un reto para el anestesiologo en la eleccion de los medicamentos a usar. Material y mtodos: Se realizo un estudio prospectivo, observacional y descriptivo del tipo casos y controles. Se estudiaron 26 pacientes en quienes se llevo a cabo algun tipo de cirugia mayor no cardiaca bajo anestesia general balanceada, teniendo como objetivo cuantificar el consumo de fentanilo transoperatorio en una poblacion homogenea. Se determino que existe menor consumo de opioides transanestesicos en el grupo al cual se le perfundio dexmedetomidina, con un valor de p < 0.05 asi como mejor calidad analgesica midiendo sta con la escala numerica del dolor. Resultados: Se concluyo que el uso de dexmedetomidina en perfusion
