Comparación del tiempo de despertar y tiempo de descarga entre dos técnicas de anestesia total intravenosa manual : Remifentanil vs Fentanil.

Abstract

Although Propofol and opioids combinations are widely used to induce and maintain adequate anesthesia and analgesia, decrease the dose of inducer, increase stability and suppress hemodynamic response to laryngoscopy and intubation, there are no studies comparing Manual Total Intravenous Anesthesia using Remifentanil - Propofol versus Fentanyl - Propofol controlled by Stangraf. Objective: To compare the time of awakening and the time of discharge between two techniques of Manual Total Intravenous Anesthesia used in the Hospital Occidente de Kennedy, one based on Propofol - Remifentanil and another based on Propofol - Fentanyl. Methods: This was an cross-sectional study done in 43 patients undergoing surgery under Total Intravenous Anesthesia in the Hospital Occidente de Kennedy. Data was analyzed using the Shapiro-Wilks, t-Student and Mann Whitney tests, and Spearman and Pearson correlation coefficients, using SPSS version 20 for Windows. A p value <0.05 was accepted as statistically significant. Results: When comparing the two techniques, we found no statistically significant differences in the evaluated times. The average awakening time was 10.1 minutes and 10.2 minutes for Fentanyl and Remifentanil respectly. The discharge time was 11.9 minutes with Fentanyl and 11.5 minutes with Remifentanil. Conclusions: the use of Propofol - Fentanyl guided by Stangraf is equivalent to the use of Remifentanil - Propofol as to the time of awakening and discharge. Further studies are required to corroborate these findings.
