1. Surviving Sepsis Campaign International Guidelines for the Management of Sepsis and Septic Shock in Children 2026.
An international panel issued 61 statements for pediatric sepsis/shock management using GRADE, including 20 new and 13 updated recommendations versus 2020. Only three statements had high or moderate certainty, highlighting persistent evidence gaps while providing practical guidance and good practice statements.
Impact: Guidelines directly shape pediatric critical care and perioperative pathways, clarifying evidence strength and practice gaps to harmonize care and prioritize research.
Clinical Implications: Clinicians should review and align local protocols to the updated graded recommendations, recognizing areas with low certainty and incorporating 'good practice' statements while supporting data collection to address gaps.
Key Findings
- 61 statements issued: 5 strong, 24 conditional, 10 good practice; 22 PICO questions without recommendations, 7 with 'in our practice' statements.
- Compared with 2020: 20 new recommendations, 13 updated, 6 reviewed unchanged, 22 carried forward.
- Only 3 recommendations were supported by high or moderate certainty of evidence, underscoring evidence limitations.
Methodological Strengths
- Multidisciplinary, international panel (68 experts from 13 organizations) with formal conflict-of-interest management.
- Systematic review with GRADE and evidence-to-decision framework ensuring transparent recommendation grading.
Limitations
- Most recommendations are based on low or very low certainty evidence, limiting definitive guidance.
- Specific clinical details of recommendations are not delineated in the abstract, necessitating full-text review.
Future Directions: Prioritize high-quality pediatric sepsis RCTs and implementation studies targeting domains with low-certainty recommendations; standardize data elements for global registries.
OBJECTIVE: To update evidence-based management recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with sepsis or septic shock. DESIGN: A panel of 68 international experts, representing 13 international organizations, as well as six methodologists, was convened. A formal conflict-of-interest policy was developed at the onset of the process and applied throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and subgroup leads, as well as within subgroups, served as an integral part of the guideline development process. METHODS: New priority topics and recommendations from the prior guideline iteration were used to identify Population, Intervention, Control, and Outcomes (PICO) questions likely to have new or updated evidence. We conducted a systematic review to identify the best available evidence, summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or conditional, or as a good practice statement. "In our practice," statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate. RESULTS: The panel provided 61 statements on the management of children with sepsis or septic shock. Overall, five were strong recommendations, 24 were conditional recommendations, and ten were good practice statements. For 22 PICO questions, no recommendations could be made, but for seven of these, "in our practice" statements were provided. Compared with the 2020 guidelines, 20 recommendations were new, 13 were updated for clarity and/or new evidence, six were reviewed but not changed, and 22 were carried forward based on consensus of the panel that new evidence was not available. Only three recommendations were based on high or moderate certainty of evidence. CONCLUSIONS: Updated management guidelines were issued by a panel of international experts for the best care of children with sepsis or septic shock, acknowledging that most aspects of care continue to have relatively low quality of evidence.
2. Prophylactic Efficacy of Cipepofol Against Postoperative Nausea and Vomiting in Moderate to High-Risk Patients of Apfel Score: A Multicenter, Randomized, and Parallel-Group Comparative Trial.
In 594 moderate-to-high Apfel risk patients, cipepofol maintenance halved 24–48 h PONV versus sevoflurane and reduced rescue antiemetic use and intraoperative hypotension. These data support cipepofol-based TIVA as an antiemetic strategy in high-risk patients.
Impact: A large multicenter randomized trial directly informs anesthetic maintenance choice to reduce PONV, a common and costly postoperative complication.
Clinical Implications: For patients with Apfel ≥2, consider cipepofol-based maintenance to reduce PONV and hypotension, while integrating standard multimodal PONV prophylaxis and local formulary considerations.
Key Findings
- Cipepofol monotherapy reduced 24-h PONV to 32.97% vs 65.75% with sevoflurane (p<0.001).
- Benefit persisted at 48 h: 35.68% vs 69.06% PONV.
- Lower rescue antiemetic use (7.03% vs 16.02%) and reduced intraoperative hypotension (9.73% vs 19.34%) with cipepofol.
Methodological Strengths
- Prospective multicenter randomized parallel-group design with sizable sample (N=594).
- Predefined primary and secondary endpoints at 24 and 48 hours with clinically meaningful outcomes.
Limitations
- Population restricted to ASA I–III, ages 18–60 undergoing noncardiac elective surgery; generalizability to elderly or high-risk patients is uncertain.
- Blinding and detailed combination-arm outcomes are not delineated in the abstract.
Future Directions: Head-to-head comparisons with propofol-based TIVA, evaluation in elderly/high-risk cohorts, cost-effectiveness, and integration with multimodal antiemetic bundles.
OBJECTIVE: This investigation systematically evaluated the antiemetic efficacy and safety of cipepofol for prophylaxis of postoperative nausea and vomiting (PONV) in surgical candidates with moderate to high Apfel risk. METHODS: A prospective, multicenter, randomized, parallel-group comparative trial was conducted at 18 clinical centers (N=594). Participants aged 18-60 years (ASA physical status I-III) with 2-4 Apfel risk factors undergoing elective noncardiac surgery were randomized into three anesthesia maintenance cohorts after cipepofol induction: cipepofol monotherapy (0.8 mg/kg/h), sevoflurane (1.5-2.0%), and combination therapy (cipepofol 0.4 mg/kg/h plus sevoflurane 1.0%). The primary endpoint was the incidence of PONV at 24 h postoperatively. Secondary endpoints included the incidence of PONV at 48 h postoperatively and intraoperative hemodynamic stability. RESULTS: Cipepofol monotherapy yielded a significantly lower 24-h PONV incidence (32.97% [95% CI, 27.1-39.2]) than sevoflurane (65.75% [59.4-71.6]; p<0.001). This difference persisted at 48 h (cipepofol: 35.68% [29.5-42.3]; sevoflurane: 69.06% [62.8-74.8]). A significantly lower proportion of patients required rescue antiemetic therapy in the cipepofol group than in the sevoflurane group within 48 h postoperatively (7.03% vs 16.02%, p=0.007). In addition, cipepofol was associated with a lower incidence of intraoperative hypotension than sevoflurane (9.73% vs 19.34%, p=0.009). CONCLUSION: Compared with sevoflurane alone, cipepofol significantly reduced PONV incidence at 24 and 48 h after surgery, with more stable intraoperative hemodynamics.
3. Quality of Bag-Mask Ventilation for Children Before Intubation: Single-Center PICU Pilot Observational Study, 2019-2022.
Among 85 PICU patients and 8,446 BMV breaths, 78% were low-quality—most commonly due to under/over tidal volume and excessive leak. Younger children had more low-quality breaths, and low-quality BMV independently tripled the odds of adverse airway outcomes.
Impact: Provides quantitative evidence that pre-intubation BMV quality is frequently suboptimal and clinically consequential, motivating training, monitoring, and protocol changes.
Clinical Implications: Adopt respiratory function monitoring during BMV, emphasize mask seal and tidal volume targeting in training, and focus on infants/young children to reduce adverse events.
Key Findings
- 78.0% of BMV breaths met at least one low-quality criterion; VTe under/over-target in 55.5% and excessive mask leak in 46.2%.
- Infants and young children had substantially more low-quality breaths than older children across multiple parameters (all p<0.001).
- Low-quality BMV independently increased odds of adverse airway outcomes 2.8-fold (adjusted OR 2.8, 95% CI 1.2–6.2).
Methodological Strengths
- Objective breath-by-breath analysis using a respiratory function monitor across 8,446 BMV breaths.
- Age-stratified analyses with adjustment for respiratory pathology.
Limitations
- Single-center pilot design limits generalizability; causal inference is limited by observational nature.
- Definitions of 'low-quality' thresholds may vary across institutions.
Future Directions: Multicenter validation, interventional training trials using quantitative feedback, and integration of BMV quality metrics into airway safety bundles.
OBJECTIVES: To characterize the quality of bag-mask ventilation (BMV) before tracheal intubation in children in the PICU and to evaluate the association between poor BMV quality and adverse airway outcomes. DESIGN: Single-center, pilot observational study, 2019-2022. SETTING: Large, urban quaternary care PICU. PATIENTS: Pediatric patients requiring BMV before tracheal intubation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Using a respiratory function monitor, we collected flow and pressure data from 8446 BMV breaths before tracheal intubation in 85 children in the PICU (median age, 3.3 yr [interquartile range, 1.4-8.3 yr]). Adverse airway outcomes (i.e., tracheal intubation-associated event and/or pulse oximetry desaturation < 80%) occurred in 14 of 85 patients (16.5%). Low-quality BMV breaths were defined as: 1) inadequate or excessive exhaled tidal volume (VTe < 4 or > 12 mL/kg); 2) excessive peak inspiratory pressure (PIP) and excessive VTe; 3) excessive facemask leak (> 40%); or 4) failure to relieve upper airway obstruction. Overall, 78.0% of BMV breaths met at least one low-quality criterion; most frequently inadequate or excessive VTe (55.5%), followed by excessive leak (46.2%). Infants (< 1 yr) and young children (1-7 yr), compared with older children (8-17 yr), had a higher proportion of low-quality BMV breaths overall (86.0%, 85.5% vs. 57.9%; p < 0.001 for both), with inadequate or excessive VTe (57.7%, 61.1% vs. 43.7%; p < 0.001 for both), excessive leak (50.6%, 49.2% vs. 37.0%; p < 0.001 for both), and excessive PIP with excessive VTe (17.5%, 19.4% vs. 6.4%; p < 0.001). After controlling for respiratory pathology, low-quality BMV was associated with 2.8-times greater odds of adverse airway outcome (adjusted odds ratio, 2.8 [95% CI, 1.2-6.2]; p = 0.01). CONCLUSIONS: The majority of BMV breaths delivered to children before tracheal intubation in the PICU were of low-quality. And, such breaths, were more frequent in younger children and were associated with greater odds of adverse airway outcomes.
