BLOOD CULTURES IN THE ION SOLCA GUAYAQUIL PEDIATRIC SERVICE JUNE 2018-2019

Abstract

INTRODUCTION: The growing resistance of microorganisms makes necessary the continuous monitoring of germs and their sensitivity to antibiotics.
MATERIALS AND METHODS: Prospective study from March 2018 to June 2019, with bacterial isolation in blood cultures and central line cultures, in febrile neutropenic patients hospitalized in the pediatric area of ION SOLCA GUAYAQUIL. Results: 634 blood cultures were taken with a positivity of 15.7%. Gram-positive bacteria 54%. Staphylococcus aureus represented 31%, Staphylococcus hominis (20%), Staphylococcus epidermidis (19%) Staphylococcus hemolyticus 17%, Staphylococcus saprophyticus 13%. Gram negative bacteria Escherichia coli dominated with 30%, Klebsiella pneumoniae 28%, Acinetobacter 18%, Pseudomonas aeruginosa 13%, Enterobacter 9%,
Proteus 2%.
Regarding bacterial sensitivity, the
Gram-positives were 100% sensitive to vancomycin, linezolid, and tigacycline; while Gram-negatives maintain a sensitivity of 80% to amikacin, 93% to imipenem and meropenem, 88% to piperacillin-tazobactam, 98% to tigecycline, 78% to ciprofloxacin, 78% to cefepime and 78% to
ceftazidime.
CONCLUSION: The incidence was higher for Gram-positive bacteria with good sensitivity to vancomycin, linezolid and tigecycline, while Gram-negative bacteria have good sensitivity to amikacin, carbapenems, piperacillin/
tazobactam and tigecycline. Carbapenemase-producing Klebsiella pneumoniae were only sensitive to tigecycline and cholestin.
