ABSTRACT

Background: this study aims to assess the organic inflammatory response of the video laparoscopic cholecystectomy, with abbreviation of the preoperative fasting to 2h using a carbohydrate and protein enriched solution.
Methods: this is a randomized, prospective study with patients divided into the following 2 groups: group A, conventional fasting and group B, 2h abbreviated fasting with oral ingestion of a carbohydrate and protein solution. Serum glucose, insulin, interleukin 1, and TNF-α were mesasured before ingestion of the solution, during induction of anesthesia, and 4 h after the end of surgery.
Results: thirty-eight patients completed the study without presenting pulmonary complications associated with bronchoaspiration. The postoperative HOMA-IR variance was greater in group A (p = 0.001).
Conclusion: the abbreviation of preoperative fasting for 2 h, using carbohydrate and protein enriched solutions, is safe, reduces insulin resistance, and does not increase the risk of bronchoaspiration.

Key words: Preoperative fasting. Carbohydrate and protein solution. Organic inflammatory response.


RESUMEN

Introduccion: El objetivo de este estudio es la evaluacion de la respuesta inflamatoria organica a la colecistectomia laparoscopica mediante video con una reduccion del tiempo de ayuno preoperatorio a 2h y empleando una solucion enriquecida con carbohidratos y proteinas.
Metodos: Se trata de un estudio aleatorizado, prospectivo con pacientes divididos en los dos grupos siguientes: grupo A, ayuno convencional y grupo B, ayuno abreviado de 2h con ingesta oral de una solucion enriquecida con carbohidratos y proteinas. Antes de la ingesta de la solucion, se hicieron mediciones de glucosa serica, insulina, interleucina 1y TNF-α; tambien se realizaron mediciones durante la induccion de la anestesia y 4h despues de la intervencion quirurgica.
Resultados: Treinta y ocho pacientes completaron el estudio sin presentar complicaciones pulmonares relacionadas con el broncoaspirado. La varianza HOMA-IR postoperatoria fue superior en el grupo A (p = 0,001).
Conclusion: La reduccion del tiempo de ayuno preoperatorio a 2h, empleando soluciones enriquecidas con carbohidratos y proteinas, es segura, reduce la resistencia a la insulina, y no aumenta el riesgo de broncoaspirado.

Palabras clave: Ayuno preoperatorio. Solución de carbohidratos y proteínas. Respuesta inflamatoria orgánica.
