Comparación del uso de ecografía vs reparos anatómicos en la realización de bloqueo caudal en pacientes de 3-7 años. Hospital Vicente corral moscoso y Hospital José Carrasco Arteaga. Cuenca 2019 a marzo 2020

Abstract

Background: The techniques advance in the use of regional anesthesia is a motivation to perform local studies that compare the use of ultrasound guidance and anatomical landmarks.

Objective: To compare the benefits of caudal block in patients from 3 to 7 years old who had been subjected surgery in the lower hemi body, both with ultrasound-guided caudal block or with anatomical landmarks.

Methodology: Observational and descriptive cross-sectional study, 124 children between 3 and 7 years old, subjected to surgery in whom a caudal block was used to alleviate postoperative pain; After intubation or before awakening, a caudal block was performed guided by ultrasound or by anatomical landmarks. The time used for each technique was measured, and in the postoperative period it was observed: vital signs, additional analgesia, the Wong Baker's Faces scale was also applied to determine the benefits of each technique.

Results: The mean age was 4.91 years. In 80.6% of the cases were male and 77.4% presenting normal weight. 55.6% of the population belonged to blockage due to anatomical repairs and 44.4% due to ultrasound guidance. Comparing the results of the 2 groups, there were found statistically significant differences, in the variation of the heart rate in favor of the group that uses ultrasound as a guide and in the duration of the procedure in favor of the group that uses anatomical repairs (less time).

Conclusions: the ultrasound-guided technique has better results in terms of analgesia than the anatomical landmarks.
