1. Surfactant therapy in neonatal care: advances, challenges, and practical considerations.
This review synthesizes clinical and translational advances in neonatal surfactant therapy, highlighting evidence favoring an initial poractant alfa dose of 200 mg/kg, increasing role of lung ultrasound to guide timing/re-treatment, and investigational SP-B/C analogs and recombinant SP-D adjuncts. It also outlines challenges in dosing harmonization, delivery efficiency, and cost-effectiveness.
Impact: Provides a current, clinically actionable synthesis of evidence that can influence neonatal dosing practice, monitoring strategies (lung ultrasound), and priorities for translational surfactant research.
Clinical Implications: Clinicians may consider an initial poractant alfa dose of 200 mg/kg where indicated, adopt lung ultrasound to time surfactant administration and re-treatment decisions, and follow emerging trials of SP-B/SP-C analogs and recombinant SP-D as potential adjuncts.
Key Findings
- Evidence supports initial poractant alfa 200 mg/kg for improved early respiratory response and lower retreatment rates compared with lower doses.
- Quantitative lung ultrasound is gaining support as a tool to guide timing and need for surfactant re-treatment.
- Translational innovations (SP-B/SP-C analogs, recombinant SP-D adjuncts) are promising but remain investigational.
Methodological Strengths
- Comprehensive literature search across PubMed/MEDLINE, Embase, and Cochrane (2000–2025) with predefined keywords.
- Integration of clinical dosing RCT data with translational/preclinical advances to provide practice-oriented recommendations.
Limitations
- Not presented as a registered systematic review with explicit PRISMA flow and formal risk-of-bias synthesis (unclear whether formal systematic methods were fully applied).
- Some emerging strategies discussed remain preclinical or early-phase, limiting immediate clinical applicability.
Future Directions: Prospective trials comparing poractant alfa dosing strategies with standardized outcomes, trials integrating lung ultrasound-guided algorithms, and further translational studies to validate SP-B/C analogs and recombinant SP-D in clinical settings.
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. Possible ARDS Following Cosmetic Lipolysis: A Case Report Urging Caution in Aesthetic Medicine.
Case report of a previously healthy 41-year-old woman who developed hypoxemic respiratory failure consistent with ARDS within 30 minutes after multiple cosmetic lipolysis injections. Macroscopic fat embolism and pulmonary embolism were excluded; microscopic fat embolism remained a possible mechanism. The patient improved with supportive care including high-flow oxygen and corticosteroids.
Impact: Draws attention to a rare but serious pulmonary complication of increasingly common cosmetic procedures, with implications for regulation and acute management protocols in aesthetic practices.
Clinical Implications: Clinicians and aesthetic providers should recognize ARDS as a potential complication after lipolysis injections, ensure early recognition and escalation (oxygen support, consider corticosteroids, transfer to higher care if hypoxemia), and advocate for better regulation and informed consent.
Key Findings
- Temporal onset of acute dyspnea and bilateral infiltrates within 30 minutes after multiple lipolysis injections in an unlicensed facility.
- Imaging and evaluation excluded pulmonary embolism and macroscopic fat embolism; microscopic fat embolism remained plausible.
- Supportive care including high-flow nasal oxygen and corticosteroids produced rapid clinical and radiological improvement.
Methodological Strengths
- Detailed timeline and diagnostic workup excluding macro causes (CT imaging, evaluation for pulmonary embolism).
- Clear clinical course with documented radiological resolution on follow-up imaging.
Limitations
- Single case report; causality cannot be definitively established, and microscopic fat embolism was not proven.
- Details on the injected substances' composition and sterility, operator technique, and exact dosing were limited (unlicensed setting).
Future Directions: Case series or registry data on complications of cosmetic lipolysis, mechanistic studies on micro‑fat embolism and standardized reporting of injection materials/procedures are needed to quantify risk and guide regulation.
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. CASE REPORT A 41-year-old Vietnamese woman with no significant past medical history developed acute progressive dyspnea and bilateral chest pain about 30 minutes after receiving multiple abdominal, shoulder, and thigh lipolysis injections at an unlicensed cosmetic facility. Chest computed tomography showed diffuse bilateral infiltrates. Pulmonary embolism and macroscopic fat embolism were excluded; however, microscopic intravascular fat embolism could not be definitively ruled out. The patient's condition rapidly progressed to hypoxemic respiratory failure consistent with ARDS. Management with high-flow nasal cannula oxygen, intravenous corticosteroids, and empiric broad-spectrum antibiotics led to significant clinical improvement within days, with near-complete radiological resolution observed on follow-up imaging. CONCLUSIONS This case illustrates ARDS as a rare but serious complication of cosmetic fat-dissolving injections. While macroscopic fat embolism was excluded, the potential role of microscopic fat embolism remains a plausible mechanism. Clinicians should recognize that lipolysis injections, often regarded as minor aesthetic procedures, carry substantial potential pulmonary risks. Greater awareness, early intervention, and stricter regulation are essential to improve patient safety.
3. Acute respiratory distress syndrome after administration of lidocaine in bronchoscopy.
A rare report of ARDS occurring after administration of lidocaine during bronchoscopy. The authors note that while lidocaine toxicity is the common adverse effect, ARDS following nontoxic doses is exceptional and merits clinician awareness.
Impact: Highlights an uncommon but serious potential adverse respiratory outcome associated temporally with topical lidocaine during bronchoscopy, prompting vigilance during peri‑procedural monitoring.
Clinical Implications: Bronchoscopists should be aware of rare severe pulmonary reactions after topical lidocaine and monitor patients closely; consider differential diagnosis including lidocaine toxicity, aspiration, and other procedure-related causes when acute respiratory deterioration occurs.
Key Findings
- Report describes ARDS temporally associated with lidocaine administered during bronchoscopy.
- Non-toxic doses of lidocaine can be followed by rare secondary reactions, including severe pulmonary complications.
- Authors emphasize rarity but clinical importance and suggest heightened vigilance during bronchoscopy.
Methodological Strengths
- Clinical relevance by focusing on a commonly used agent in a routine procedure.
- Concise description suitable for raising a safety signal to the clinical community.
Limitations
- Single-case report; lacks systematic investigation to confirm causality or mechanism.
- Limited clinical detail in abstract alone (full text may be needed to appraise diagnostic workup and management).
Future Directions: Collect additional cases or case series, and conduct mechanistic studies to determine whether topical lidocaine can trigger inflammatory lung injury or other pathways leading to ARDS.
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.
