Summary
The strongest contributions were a large prospective registry study identifying substantial postoperative bleeding after tonsil surgery, a health-systems framework positioning pediatric anesthesia as essential infrastructure for global children's surgery, and a critical review showing that routine truncal blocks provide limited additional benefit over optimized multimodal analgesia in ambulatory surgery. Collectively, these papers emphasize quality improvement, systems-level anesthesia capacity, and evidence-based restraint in procedural adoption.
Research Themes
- Perioperative safety and quality improvement
- Pediatric anesthesia as a global health-system function
- Evidence-based optimization of regional analgesia in ambulatory surgery
Selected Articles
1. High Bleeding Rates After Tonsil Surgery in Denmark and Opportunities for Quality Improvement.
This multicentre prospective registry cohort analyzed 6145 tonsil procedures performed in Denmark from 2018 to 2024. Postoperative bleeding occurred in 14% after tonsillectomy and 1.7% after tonsillotomy; male sex and resident-performed surgery were associated with higher adjusted risk, while younger age was associated with lower risk.
Impact: The study provides contemporary, multicentre, real-world estimates of a clinically important anesthetic and surgical complication, including the proportion of bleeding events requiring general anesthesia. Its findings identify actionable patient- and system-level targets for perioperative risk counseling and quality improvement.
Clinical Implications: Patients and families should be counseled that post-tonsillectomy bleeding is relatively common and may require reoperation under general anesthesia. Institutions should monitor procedure-specific bleeding rates, examine operator and age-related differences, and develop structured quality-improvement interventions rather than relying solely on operative technique selection.
Key Findings
- Among 6145 procedures, postoperative bleeding occurred after 14% of tonsillectomies, 9.9% of adenotonsillectomies, 10% of acute tonsillectomies, 1.7% of tonsillotomies, and 2.6% of adenotonsillotomies.
- Among bleeding events, 51% required general anesthesia, 32% required local anesthesia, and 17% resolved spontaneously.
- After tonsillectomy, male sex increased adjusted risk, whereas age below 18 years was associated with lower risk than adulthood; no deaths occurred.
Methodological Strengths
- Multicentre cohort design using prospectively collected registry data over six years.
- Large sample size with adjusted relative-risk analysis using modified Poisson regression and robust standard errors.
Limitations
- The observational design cannot establish causality for associations between patient, operator, or surgical factors and bleeding.
- The study was conducted in five Danish departments, so results may not generalize to healthcare systems with different surgical practices or perioperative pathways.
Future Directions: Future work should evaluate standardized quality-improvement interventions, patient-reported outcomes, indications for reoperation, and center-level or surgeon-level variation. Comparative analyses should also examine how perioperative analgesia, hemostatic protocols, and discharge pathways influence bleeding-related morbidity.
OBJECTIVES: To examine postoperative bleeding rates and associated patient and surgical factors after tonsil surgery in Denmark and identify targets for quality improvement. DESIGN: Multicentre cohort study using prospectively collected registry data. SETTING: Five Danish ENT departments contributing to the Danish Tonsil Database, 2018-2024. PARTICIPANTS: Children, adolescents and adults undergoing tonsillectomy, adenotonsillectomy, tonsillotomy, adenotonsillotomy or acute tonsillectomy for benign indications.
2. Safe Surgery Starts With Safe Anesthesia: Positioning Pediatric Anesthesia as a Core Health-System Function Within Global Children's Surgical Systems.
This perspective argues that children's surgical systems cannot be strengthened without parallel investment in pediatric anesthesia. It integrates WHO Health Systems Building Blocks, global surgery frameworks, National Surgical, Obstetric and Anesthesia Plans, the GICS Optimal Resources for Children's Surgery framework, and Donabedian's Structure-Process-Outcome model into an Integrated Pediatric Anesthesia Systems Framework.
Impact: The paper reframes pediatric anesthesia from a supporting specialty into a cross-cutting health-system function that determines whether children's surgery can be delivered safely and equitably. This systems-level argument is particularly important for low- and middle-income countries, where anesthesia capacity is a major constraint on surgical access.
Clinical Implications: National and institutional surgical plans should include pediatric anesthesia workforce, age-appropriate equipment, oxygen and monitoring infrastructure, recovery services, critical care, financing, training, and quality measurement. Pediatric anesthesia should be incorporated into global surgery investment decisions and perioperative safety programs rather than treated as an ancillary resource.
Key Findings
- Safe children's surgery requires coordinated pediatric anesthesia capacity, including trained personnel, appropriate equipment, monitoring, oxygen, medications, recovery, and critical care.
- The Integrated Pediatric Anesthesia Systems Framework links health-system inputs and processes to perioperative outcomes across the continuum of care.
- Pediatric anesthesia should be included in government policy, workforce development, financing, service delivery, quality improvement, education, and research agendas.
Methodological Strengths
- Integrates multiple established global surgery and health-system frameworks rather than presenting an isolated conceptual opinion.
- Uses the Structure-Process-Outcome model to connect infrastructure and service delivery with measurable perioperative outcomes.
Limitations
- The framework is conceptual and does not provide prospective validation or comparative outcome data.
- Implementation priorities may differ across countries because workforce, financing, infrastructure, and referral systems are heterogeneous.
Future Directions: Future research should operationalize the framework into measurable indicators and test whether investments in pediatric anesthesia capacity improve access, perioperative mortality, morbidity, recovery, and equity. Implementation studies should compare context-adapted models across low-, middle-, and high-income settings.
BACKGROUND: Children's surgery is increasingly recognized as a global health priority, yet pediatric anesthesia remains comparatively under-recognized despite being essential for safe surgical and perioperative care. THE PROBLEM: Children require specialized expertise, age-appropriate equipment, reliable monitoring, oxygen, medicines, recovery, and critical care. In many low- and middle-income countries, deficiencies across these domains limit access and contribute to preventable perioperative morbidity and mortality. THE CENTRAL CLAIM: We posit that children's surgical systems cannot be strengthened without parallel investment in pediatric anesthesia systems.
3. Truncal blocks in ambulatory surgery: what is the evidence?
This review evaluates truncal blocks against realistic multimodal analgesic comparators in ambulatory surgery. Benefits were generally small and procedure-dependent: transversus abdominis plane and rectus sheath blocks were often neutral compared with wound infiltration, quadratus lumborum block showed no clinically important superiority, and evidence for erector spinae, pectoral, and serratus plane blocks remained heterogeneous.
Impact: The review challenges routine expansion of regional blocks by emphasizing patient-centered endpoints such as discharge, recovery at home, and rebound pain rather than short-term inpatient analgesic scores alone. It supports selective, procedure-specific use and prevents adoption of resource-intensive interventions without clinically meaningful benefit.
Clinical Implications: Routine truncal blocks should not replace optimized multimodal analgesia for ambulatory surgery. Block selection should be individualized according to the procedure, expected pain burden, expertise, antithrombotic status, monitoring requirements, and discharge goals; paravertebral block may be effective for major breast surgery but is less suitable for routine day-case pathways.
Key Findings
- Transversus abdominis plane and rectus sheath blocks showed neutral results compared with wound infiltration, while quadratus lumborum block lacked clinically important superiority.
- Erector spinae plane block showed early analgesic signals, but heterogeneity and negative multicentre evidence limited generalizability.
- Only two randomized trials prespecified day-case or discharge endpoints, and evidence for discharge, home recovery, and rebound pain remains insufficient.
Methodological Strengths
- Evaluates blocks against realistic contemporary multimodal comparators rather than against weak or outdated analgesic regimens.
- Prioritizes clinically meaningful ambulatory outcomes and explicitly considers procedural burden, expertise, antithrombotic precautions, and monitoring requirements.
Limitations
- The review is limited by heterogeneity in block techniques, local anesthetic regimens, surgical procedures, and comparator pathways.
- The available evidence contains few trials with discharge, home recovery, or rebound-pain endpoints, limiting conclusions about patient-centered ambulatory outcomes.
Future Directions: Future trials should be procedure-specific, compare blocks with optimized multimodal analgesia, and prespecify discharge readiness, time at home, functional recovery, opioid use, adverse effects, and rebound pain. Pragmatic multicentre studies should also evaluate cost, workflow, training requirements, and patient preferences.
PURPOSE OF REVIEW: Truncal blocks are increasingly used in ambulatory pathways, although evidence predominantly concerns short-term inpatient outcomes. This review evaluates clinically important, procedure-specific benefits over realistic multimodal comparators. RECENT FINDINGS: Benefits are small and comparator-dependent. Trials comparing laparoscopic transversus abdominis plane and rectus sheath blocks with wound infiltration were neutral; quadratus lumborum block showed no clinically important superiority. Erector spinae plane block provides early analgesic signals, but heterogeneity and negative multicentre evidence limit generalizability.
