Flow blocks in pediatric patients

Abstract

This research characterizes the hemodynamic behavior of pediatric caudal blocks subjected to surgeries of the lower hemiabdomen and inguinal region, in the General Teaching Hospital of Calderón (HGDC), Quito-Ecuador, in the period June-December 2019; Furthermore, the demographic characteristics of the study population are described, determining the intensity of pain with the visual analog scale (VAS). Likewise, hemodynamic changes are reported at the different times established in the study, verifying the use of rescue analgesics and the search for adverse effects with the use of this technique. This is a retrospective descriptive study, considering the entire study population (32 patients). Statistical analysis was performed with measures of frequency and central tendency (median), dispersion (standard deviation, range). Regarding the results of the VAS, it is important to highlight that despite giving a statistically significant difference (p <0.05), in medical practice this scale remains below 1 point, that is, mild pain; hemodynamic variables remained stable with respect to pre lock. With the use of rescue analgesics, only a 3.1% patient was reported, who was administered rescue doses. The adverse effects reported with caudal block were: nausea 6.3%, somnolence 3.1%, and no effect with 90.6% respectively. The caudal block provides excellent postoperative analgesia according to the VAS at the different times in the study.
