Maternal Sepsis and Septic Shock

Objective Sepsis is a life-threatening syndrome caused by the body's response to infection. The Global Maternal Sepsis Study (GLOSS) suggests sepsis plays a larger role in maternal morbidity and mortality than previously thought. We therefore sought to compare national and international guidelines for maternal sepsis to determine their consistency with each other and the Third International Consensus for Sepsis and Septic Shock (SEPSIS-3). Study Design Using Cochrane Database of Systematic Reviews, PubMed, Google Scholar, and organization Web sites, we identified seven guidelines on maternal sepsis in the English language—The American College of Obstetricians and Gynecologists, Society for Maternal-Fetal Medicine, Royal Australian and New Zealand College of Obstetricians and Gynaecologists, Society of Obstetric Medicine of Australia and New Zealand, Royal College of Obstetricians and Gynaecologists, Royal College of Physicians of Ireland Institute of Obstetricians and Gynaecologists, and World Health Organization. Guidelines were reviewed to ascertain the commonality and variation, if any, in definitions of maternal sepsis, tools and criteria utilized for diagnosis, obstetric warning systems used, as well as evaluation and management of maternal sepsis. These variables were also compared with SEPSIS-3. Results All guidelines provided definitions consistent with a version of the SEPSIS, although the specific version utilized were varied. Clinical variables and tools employed for diagnosis of maternal sepsis were also varied. Evaluation and management of maternal sepsis and septic shock were similar. Conclusion In conclusion, national and international maternal sepsis guidelines were incongruent with each other and SEPSIS-3 in diagnostic criteria and tools but similar in evaluation and management recommendations.

Sepsis And Septic Shock

Objectives: to evaluate the fluid responsiveness according to fluid bolus triggers and their combination in severe sepsis and septic shock. Design: observational study. Patients and Methods: patients with severe sepsis and septic shock who already received fluid after rescue phase of resuscitation. Fluid bolus (FB) was prescribed upon perceived hypovolemic manifestations: low central venous pressure (CVP), low blood pressure, tachycardia, low urine output (UOP), hyperlactatemia. FB was performed by Ringer lactate 500 ml/30 min and responsiveness was defined by increasing in stroke volume (SV) ≥15%. Results: 84 patients were enrolled, among them 30 responded to FB (35.7%). Demographic and hemodynamic profile before fluid bolus were similar between responders and non-responders, except CVP was lower in responders (7.3 ± 3.4 mmHg vs 9.2 ± 3.6 mmHg) (p 0.018). Fluid response in low CVP, low blood pressure, tachycardia, low UOP, hyperlactatemia were 48.6%, 47.4%, 38.5%, 37.0%, 36.8% making the odd ratio (OR) of these triggers were 2.81 (1.09-7.27), 1.60 (0.54-4.78), 1.89 (0.58-6.18), 1.15 (0.41-3.27) and 1.27 (0.46-3.53) respectively. Although CVP < 8 mmHg had a higher response rate, the association was not consistent at lower cut-offs. The combination of these triggers appeared to raise fluid response but did not reach statistical significance: 26.7% (1 trigger), 31.0% (2 triggers), 35.7% (3 triggers), 55.6% (4 triggers), 100% (5 triggers). Conclusions: fluid responsiveness was low in optimization phase of resuscitation. No fluid bolus trigger was superior to the others in term of providing a higher responsiveness, their combination did not improve fluid responsiveness as well.
