Background: Retinoblastoma (RB) is the most common intraocular malignancy diagnosed in early childhood. Treatment is extensive, requiring multiple general anesthetics to facilitate eye examinations. However, little is known how repeated exposure to general anesthesia in early childhood affects cognitive function in RB survivors.

Purpose: The purpose of this cross-sectional study was to examine the effects of anesthesia exposure on cognition in 14- to 26-year-old RB survivors compared with those in healthy controls.

Methods: Patients who previously received care for RB (n = 98) were recruited and compared to a cohort of healthy subjects (n = 97). Participants' cognitive functioning was assessed using the Montreal Cognitive Assessment (MoCA). MoCA scores were compared between groups using Wilcoxon rank-sum tests. Relationships between MoCA scores and anesthesia exposure were assessed using Spearman's rank correlation coefficients. Multiple regression was used to evaluate the effect of anesthesia (both before the age of three and throughout childhood) on cognition.

Results: RB patients scored significantly lower than controls on the MoCA and several of its subscales (Naming, Attention, Language, and Abstraction; adjusted ps < 0.05). Total childhood anesthesia exposure was negatively associated with MoCA total scores (ρ = -0.19, p = 0.009) and some subscale scores. In regression models adjusted for covariates, each time anesthesia was administered before the age of three (β = -0.06, p = 0.02) or throughout childhood (β = -0.04, p = 0.005) was associated with a small but statistically significant decrease in cognition. Hollingshead socioeconomic status (β = 0.04, p = 0.001) and public insurance (β = -1.75, p < 0.0001) were stronger predictors of MoCA total scores than anesthesia exposure.

Conclusion: Despite any effects of repeated anesthesia exposure in early childhood on cognition, MoCA scores for RB survivors were in the normal range. These findings add to the developing research on neurocognitive effects of anesthesia in early childhood in a population with large anesthesia exposure and minimal confounding factors. Future research should include additional measures of neurodevelopmental functioning and focus on the at-risk low socioeconomic status population. Continued follow-up and assessment of visual function in bilateral survivors are imperative.

Background: Healthcare accounts for 4%-5% of global CO₂ equivalent (CO₂e) emissions, of which hospitals form a considerable component. Identifying evidence-based targets for carbon reduction in pediatric anesthesia can help guide meaningful reductions in healthcare-related environmental harm.

Methods: A narrative review was conducted integrating published data on carbon emissions associated with anesthetic agents, perioperative workflows, waste generation, and hospital energy systems. Quantitative CO₂e estimates were incorporated when available.

Results: Preoperative strategies with measurable carbon savings include early anesthesia assessment, telehealth consultations, and standardization of diagnostic testing. Intraoperatively, avoidance of nitrous oxide and desflurane yield the largest individual reductions. Propofol waste can be reduced through dose calculators and optimized vial selection. Switching to reusable equipment further limits environmental harm. Institutional actions, including decommissioning nitrous oxide pipeline systems, enhancing sustainability training, and optimizing heating, ventilation, and air conditioning systems, offer the largest measurable carbon reductions.

Conclusions: Pediatric anesthetists can reduce environmental harm while optimizing patient care. While individual clinician choices -in particular avoiding desflurane and nitrous oxide use-are impactful, the largest and most sustainable emissions reductions derive from coordinated institutional and systems level changes.

Background: Preoperative anxiety is common in young children and may impair cooperation during anesthesia induction. Some temperament traits have been associated with higher anxiety levels in the preoperative phase. While midazolam is widely used for anxiolysis, individual responses vary and may be influenced by underlying psychological characteristics such as temperament.

Aims: This study aimed to examine the association between specific temperament traits and preoperative anxiety in young children and to determine whether these associations persist after midazolam administration.

Methods: This secondary analysis of the ALPAKA trial examined associations between temperament and perioperative anxiety in children aged 2-8 years undergoing elective surgery. Temperament was assessed using the parent-reported Integrative Child Temperament Inventory (ICTI). Anxiety was rated at two time points before (T1) and after (T2) midazolam administration using the modified Yale Preoperative Anxiety Scale-Short Form (mYPAS-SF). Additional variables included the Strengths and Difficulties Questionnaire (SDQ) scores, baseline characteristics and prior emotional distress. Spearman correlation (r_s), multivariable and univariate logistic regression analyses were conducted to identify predictors of elevated anxiety (defined as mYPAS-SF > 30).

Results: Eighty-nine children were included in the final analysis. Behavioral inhibition was associated with anxiety at both T1 (r_s = 0.35, 95% CI 0.15-0.53, p = 0.001) and T2 (r_s = 0.46, 95% CI 0.28-0.62, p < 0.001). No significant associations were found for other IKT or SDQ subscales. Logistic regression showed that male sex (OR 3.16, 95% CI 1.36-7.19, p = 0.011) and prior anesthesia experience (OR 4.28, 95% CI 1.78-10.39, p = 0.001) were independently associated with elevated anxiety at T1. A multivariable logistic regression for behavioral inhibition adjusted by sex and prior anesthesia showed for T1 a positive association with elevated anxiety (OR 1.02, 95% CI 1.00-1.05). For T2, the corresponding model showed limited explanatory power.

Conclusion: Behavioral inhibition is a robust predictor of perioperative anxiety in young children, both before and after midazolam administration. Brief screening for inhibition may help identify children at increased risk and guide individualized, risk-adapted strategies in pediatric anesthesia.

Background: In recent years, health systems worldwide have increasingly expanded patient and guardian access to clinical records. While adult patient perspectives on anesthetic records have been explored, little is known about how pediatric guardians interpret and engage with their child's anesthetic documentation.

Aims: To explore how guardians of pediatric patients engage with their child's anesthetic record and to identify elements they perceive as meaningful, confusing, or emotionally impactful.

Methods: We conducted a qualitative study using semi-structured video conference interviews between April 2023 and August 2024 with guardians of pediatric patients undergoing outpatient surgery under general anesthesia at a quaternary academic pediatric hospital. Twenty English-speaking guardians of children classified as American Society of Anesthesiologists Physical Status I-II and receiving anesthesia via endotracheal tube or supraglottic airway were recruited using a semi-purposive convenience sampling approach. During interviews, guardians reviewed their child's record via screen share and provided real-time feedback. Interviews were audio-recorded, transcribed verbatim, and analyzed using inductive and deductive thematic coding until thematic saturation was reached.

Results: Guardians identified several elements of the anesthetic record as meaningful, including medications administered, provider involvement, event timelines, and their child's reactions to anesthesia. However, they reported confusion due to unexplained abbreviations, medical jargon, non-chronological data presentation, unclear visual formatting, and perceived inaccuracies. Interpretation was influenced by guardians' comfort level with health information, emotional state, and considerations unique to pediatric care. Emotional responses ranged from reassurance to anxiety; while some guardians found the record useful for future care planning, others described elements as distressing or difficult to interpret.

Conclusions: Guardians face substantial barriers when interpreting pediatric anesthetic records. As patient-accessible records become increasingly common across health systems globally, improving anesthetic record design is essential. Plain-language summaries, visual annotations, and pediatric-specific contextual guidance could improve comprehension, reduce misinterpretation, and facilitate better collaboration between guardians and clinicians during perioperative care.
