1. Surfactant therapy in neonatal care: advances, challenges, and practical considerations.
This review integrates mechanistic and clinical advances in neonatal surfactant therapy. It supports poractant alfa 200 mg/kg initial dosing, highlights quantitative lung ultrasound for timing and re-treatment, and outlines promising SP-B/SP-C analogs and recombinant SP-D that require further validation.
Impact: Provides an updated synthesis across mechanisms, dosing, delivery, and monitoring, with practical takeaways for individualized neonatal respiratory care.
Clinical Implications: For preterm RDS, consider 200 mg/kg poractant alfa as initial dosing and use quantitative lung ultrasound to guide timing and re-treatment; emerging SP-based strategies remain investigational.
Key Findings
- Evidence supports initial poractant alfa 200 mg/kg for better early response and less re-treatment versus lower doses.
- Quantitative lung ultrasound is increasingly supported to guide timing and re-treatment decisions.
- Emerging SP-B/SP-C analog formulations and recombinant SP-D-based adjuncts show promise but require validation.
- Challenges remain in dosing optimization, delivery efficiency, outcome harmonization, and cost-effectiveness.
Methodological Strengths
- Multi-database search (PubMed/MEDLINE, Embase, Cochrane) with predefined keywords (2000–2025).
- Integrates mechanistic roles of SP-A, SP-B, SP-C, SP-D with clinical evidence and practice.
Limitations
- Appears narrative without explicit PRISMA adherence or meta-analysis.
- Heterogeneity across included studies; several strategies remain investigational.
Future Directions: Prospective trials to validate SP-analog and recombinant SP-D strategies; randomized studies of lung ultrasound–guided dosing with standardized outcomes and cost-effectiveness analyses.
Surfactant therapy is a cornerstone of neonatal care for preterm respiratory distress syndrome (RDS). This review summarizes recent advances in surfactant therapy, focusing on surfactant composition and the clinical roles of surfactant proteins (SP-A, SP-B, SP-C, and SP-D), and highlights emerging strategies to optimize dosing and monitoring. We searched PubMed/MEDLINE, Embase, and the Cochrane Library for studies published between 2000 and 2025 using predefined keywords related to surfactant therapy, dosing, formulations, delivery techniques, monitoring, and outcomes. Evidence supports poractant alfa at an initial 200 mg/kg dose for improved early respiratory response and reduced need for re-treatment compared with lower dosing, and quantitative lung ultrasound is increasingly supported to guide surfactant timing and re-treatment decisions. Emerging innovations include SP-B/SP-C analog formulations and recombinant SP-D-based adjunct approaches, although several strategies remain investigational and require further validation.Conclusion: Key ongoing challenges include optimizing dosing and delivery efficiency, harmonizing monitoring and outcome definitions across studies, and improving cost-effectiveness. Overall, this review provides an updated critical perspective on surfactant therapy and future directions toward more individualized neonatal respiratory care.
2. Acute respiratory distress syndrome after administration of lidocaine in bronchoscopy.
This case report documents ARDS occurring after lidocaine administration during bronchoscopy, highlighting an exceptional adverse reaction beyond classic lidocaine toxicity. It underscores vigilance for severe pulmonary complications even at non-toxic dosing.
Impact: Adds a rare but serious pharmacovigilance signal linking bronchoscopy lidocaine use to ARDS, informing procedural safety.
Clinical Implications: During bronchoscopy, maintain readiness for hypoxemic deterioration after lidocaine administration, monitor closely post-application, and consider alternative strategies in high-risk patients.
Key Findings
- ARDS occurred following lidocaine administration for bronchoscopy.
- Non-toxic dose reactions to lidocaine are infrequent; ARDS in this context is exceptional.
- Lidocaine toxicity is the most common adverse reaction, but this report highlights a distinct severe complication.
Methodological Strengths
- Peer-reviewed documentation of a rare, severe adverse event.
- Contributes to pharmacovigilance by highlighting an exceptional reaction.
Limitations
- Single-patient case report limits causal inference.
- Diagnostic and mechanistic details are not provided in the abstract.
Future Directions: Systematic collection of bronchoscopy-related adverse events and mechanistic studies on local anesthetic–associated lung injury.
Lidocaine is the most commonly used local anaesthetic agent for bronchoscopy, and adverse reactions secondary to its use have rarely been reported. Among the possible adverse reactions, the most common is lidocaine toxicity. Secondary reactions to the use of nontoxic doses of lidocaine are infrequent, and acute respiratory distress syndrome following its administration is exceptional.
3. Possible ARDS Following Cosmetic Lipolysis: A Case Report Urging Caution in Aesthetic Medicine.
A previously healthy woman developed ARDS about 30 minutes after multiple cosmetic lipolysis injections at an unlicensed facility. Imaging showed diffuse bilateral infiltrates; pulmonary embolism and macroscopic fat embolism were excluded, microscopic fat embolism remained plausible, and supportive care with steroids and antibiotics led to rapid improvement.
Impact: Highlights a rare, serious pulmonary complication of a common aesthetic practice and emphasizes regulatory and clinical vigilance.
Clinical Implications: Clinicians should recognize ARDS risk after lipolysis injections, ensure early evaluation and supportive management for hypoxemia, and advocate for regulation of unlicensed aesthetic practices.
Key Findings
- Acute progressive dyspnea and bilateral chest pain developed ~30 minutes after multiple lipolysis injections at an unlicensed facility.
- CT showed diffuse bilateral infiltrates; pulmonary embolism and macroscopic fat embolism were excluded.
- Microscopic intravascular fat embolism remained a plausible mechanism but was not definitively proven.
- Management with high-flow nasal cannula oxygen, intravenous corticosteroids, and empiric broad-spectrum antibiotics led to rapid clinical and radiologic improvement within days.
Methodological Strengths
- Detailed temporal relationship, imaging, and management course documented.
- Differential diagnosis addressed with exclusion of pulmonary embolism and macroscopic fat embolism.
Limitations
- Single-patient case limits generalizability and causal inference.
- No pathological confirmation of microscopic fat embolism; unregulated setting introduces potential confounders.
Future Directions: Establish registries of complications after aesthetic injections and conduct mechanistic and imaging studies to clarify microembolism-related lung injury.
BACKGROUND Fat-dissolving (lipolysis) injections are increasingly performed as non-surgical aesthetic procedures for body contouring. Although generally considered safe, these interventions can rarely result in severe and potentially life-threatening complications, especially in unregulated settings. We report an unusual case of acute respiratory distress syndrome (ARDS) following cosmetic lipolysis injections in a previously healthy woman.
