Abstract

Introduction: Comparatively, culture-negative septic shock or septic shock (CNSS) is frequently observed among pediatric patients, contrasting with the more distinct clinical profile and prognosis of post-surgical septic shock (CPSS). However, limited data are available on the outcomes of CNSS in comparison to CPSS in pediatric patients. This study seeks to conduct a systematic review and meta-analysis of existing literature to comprehensively compare outcomes between CNSS and CPSS in pediatric patients.

Methods: Electronic databases, such as PubMed, CINAHIL, and EMBASE, were systematically searched up to January 15, 2024, using predefined terms. We included all studies that compared outcomes between CPSS and CNSS in pediatric patients. The primary outcome evaluated in this study was all-cause mortality. Secondary outcomes included length of hospitalization, length of intensive care unit (ICU) stay, and duration of mechanical ventilation (all measured in days).

Results: Among the initially identified 1328 articles, six studies involving 2511 pediatric patients met the inclusion criteria and were part of this meta-analysis study. The pooled analysis revealed no significant differences in all-cause mortality (odds ratio: 1.26, 95% confidence interval (CI): 0.93 to 1.70, = 0.14), length of ICU stay (mean difference (MD): 0.18, 95% CI: -0.33 to 0.68, = 0.50), and duration of mechanical ventilation (MD: -0.74, 95% CI: -2.46 to 0.98, -value = 0.40) between CPSS and CNSS. However, the length of hospital stay was longer in CPSS compared to CNSS (MD: 7.38, 95% CI: 5.50 to 9.27, < 0.0001).

Conclusion: Approximately 26.56% of pediatric septic cases were culture-positive. There were no statistically significant differences in mortality, ICU stay, and duration of mechanical ventilation between CPSS and CNSS. However, hospital stay was prolonged by more than 7 days in culture-positive cases. Further multicenter studies are warranted to validate these findings and explore additional presentation characteristics.
