Summary

Today’s most impactful anesthesiology research includes a multicentre randomized trial showing that videolaryngoscopy improves first-attempt nasotracheal intubation success in infants undergoing cardiac procedures. A meta-analysis of 22 randomized trials found that ciprofol provides comparable bronchoscopic sedation with fewer hypotensive, injection-pain, hypoxemic, and respiratory-depression events than propofol. A large retrospective cohort further demonstrated that artificial intelligence-derived cardiovascular indices from routine preoperative chest radiographs provide modest incremental prediction of postoperative major adverse cardiovascular events.

The Lancet. Child & adolescent health2026PMID: 42945985

In this multicentre randomized trial of 673 evaluable infants, first-attempt nasotracheal intubation success was significantly higher with videolaryngoscopy than with direct laryngoscopy: 83% versus 75%, with an adjusted risk difference of 8.2%. First-attempt and cumulative complication rates were similar, and no cardiac arrest or death occurred in either group.

Impact: This is high-quality randomized evidence addressing a clinically important and previously uncertain question in infant airway management. An 8.2% absolute improvement in first-attempt success may reduce repeated airway manipulation and supports videolaryngoscopy as a first-line technique in appropriately equipped pediatric cardiac settings.

Clinical Implications: Videolaryngoscopy should be strongly considered as the initial device for nasotracheal intubation in infants undergoing elective cardiac procedures, particularly where trained operators and appropriate equipment are available. The findings should not yet be generalized to anticipated difficult airways, emergency settings, or non-specialist centers.

Key Findings

  • First-attempt nasotracheal intubation success was 83% with videolaryngoscopy versus 75% with direct laryngoscopy.
  • The adjusted risk difference in first-attempt success was 8.2% (95% CI, 2.0%-14.3%; p = 0.0093).
  • First-attempt and cumulative complication rates were similar, and no cardiac arrest or death occurred.

Methodological Strengths

  • Multicentre parallel-group randomized controlled design with site-stratified allocation.
  • Modified intention-to-treat analysis using generalized estimating equations to account for clustering by intubating clinician.

Limitations

  • Participants had no anticipated difficult airway and were treated in specialized pediatric cardiac centers.
  • The study does not establish whether the benefit extends to emergency procedures, difficult airways, or non-specialist hospitals.

Future Directions: Future studies should evaluate videolaryngoscopy in infants with anticipated difficult airways, urgent or emergency procedures, and lower-volume centers, while assessing device-specific performance, training requirements, and cost-effectiveness.

BACKGROUND: Nasotracheal intubation is a common procedure for infants undergoing surgery, and successful intubation at first attempt reduces the risk of complications. First-attempt success is improved with videolaryngoscopy compared with direct laryngoscopy in infants requiring orotracheal intubation, but the value of videolaryngoscopy in infants requiring nasotracheal intubation is unknown. We aimed to compare first-attempt success of nasotracheal intubation by videolaryngoscopy and direct laryngoscopy in infants undergoing cardiac procedures.

2. Comparative Efficacy and Safety of Ciprofol Versus Propofol in Adults Undergoing Fiberoptic Bronchoscopy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

This meta-analysis included 22 randomized controlled trials involving 2,452 participants undergoing fiberoptic bronchoscopy. Compared with propofol, ciprofol had similar procedural success and recovery outcomes but significantly lower risks of hypotension, injection pain, hypoxemia, and respiratory depression.

Impact: The study quantitatively synthesizes the largest evidence base among the selected pharmacologic comparisons and identifies a consistent safety signal for a newer sedative. Its findings may support broader clinical evaluation of ciprofol, although implementation should await confirmation in standardized, multicentre trials and diverse patient populations.

Clinical Implications: Ciprofol may be considered an alternative to propofol for fiberoptic bronchoscopy when hypotension, injection pain, hypoxemia, or respiratory depression are major concerns. Choice of sedative should still account for local availability, cost, clinician experience, patient comorbidity, and monitoring and rescue capabilities.

Key Findings

  • Twenty-two randomized controlled trials with 2,452 participants were included.
  • Ciprofol reduced hypotension compared with propofol (RR 0.39; 95% CI, 0.28-0.55).
  • Ciprofol also reduced injection pain, hypoxemia, and respiratory depression, while procedural success and recovery outcomes were comparable.

Methodological Strengths

  • Systematic review and meta-analysis restricted to randomized controlled trials.
  • Evaluation of multiple efficacy and safety outcomes using risk ratios and mean differences with confidence intervals.

Limitations

  • The abstract does not provide detailed risk-of-bias results, heterogeneity estimates, or the geographic distribution of the trials.
  • The evidence is limited to fiberoptic bronchoscopy and may not generalize to other procedures, high-risk patients, or long-term safety outcomes.

Future Directions: Future research should use multicentre pragmatic trials with standardized dosing, sedation targets, monitoring protocols, rescue criteria, and patient-centered recovery outcomes, including cost-effectiveness and longer-term safety.

Background: Ciprofol, a novel intravenous sedative, has recently gained increasing clinical attention for procedural anesthesia. Emerging evidence suggests it may possess potential safety advantages over propofol. This study aimed to systematically compare the efficacy and safety of ciprofol and propofol for sedation in patients undergoing fiberoptic bronchoscopy. Methods: A comprehensive literature search was conducted in eight electronic databases. Statistical analyses were performed using the R software (version 4.5.2). The risk ratio (RR) with 95% confidence interval (CI) was used for dichotomous outcomes, and the mean difference (MD) with 95% CI was used for continuous outcomes.

3. AI-Powered Preoperative Chest Radiograph-Derived Cardiovascular Border Indices and Risk of Postoperative Major Adverse Cardiovascular Events: A Large-Scale Retrospective Cohort Study.

Among 101,531 patients undergoing surgery under general anesthesia, artificial intelligence-derived cardiomediastinal vascular border metrics from routine preoperative chest radiographs were independently associated with in-hospital postoperative major adverse cardiovascular events. Adding cardiothoracic ratio or a composite cardiovascular-border z-score to a clinical model increased the AUC from 0.894 to 0.906, with similar improvement in temporal validation.

Impact: This study demonstrates how routinely acquired, low-cost imaging may be transformed into quantitative perioperative risk information without additional patient burden. Its very large cohort and temporal validation strengthen the signal, while the modest incremental discrimination appropriately highlights that clinical utility still requires external validation.

Clinical Implications: Automated analysis of preoperative chest radiographs could eventually support cardiovascular risk stratification, particularly when radiographs are already obtained for routine care. It should currently be considered an adjunct to, rather than a replacement for, clinical assessment because external validation, calibration across institutions, and prospective impact studies are still required.

Key Findings

  • Among 101,531 surgical patients, 1,655 (1.6%) experienced in-hospital postoperative major adverse cardiovascular events.
  • The adjusted odds ratio for cardiothoracic ratio was 1.64 (95% CI, 1.58-1.70), with an AUC of 0.789.
  • Adding cardiothoracic ratio or a composite cardiovascular-border z-score increased the clinical model AUC from 0.894 to 0.906.

Methodological Strengths

  • Very large real-world retrospective cohort with more than 100,000 surgical patients.
  • Assessment of incremental discrimination beyond clinical factors and confirmation using temporal validation.

Limitations

  • The retrospective single-center design may introduce selection bias and limit generalizability.
  • The increase in AUC was modest, and external validation and prospective clinical impact assessment were not established.

Future Directions: Future studies should externally validate the model across hospitals, imaging devices, patient populations, and surgical specialties; assess calibration and fairness; and determine whether AI-assisted alerts change perioperative management and patient outcomes.

Background and Objectives: Routine preoperative chest radiography (CXR) has limited value for perioperative risk prediction when interpreted qualitatively. The Automated Diagnosis of Cardiovascular abnormalities (ADC) model enables automated quantification of cardiomediastinal vascular border (CVB) parameters on CXR. This study evaluated the associations of AI-derived CVB metrics with postoperative major adverse cardiovascular events (MACE) and their incremental predictive value beyond clinical factors. Materials and Methods: This retrospective cohort study included patients who underwent surgery under general anesthesia at a tertiary academic center.
