Background: Emergence delirium is a well-known and common problem in children recovering from anesthesia. The five-item Pediatric Anesthesia Emergence Delirium scale is one of the most commonly used instruments for assessing this condition, but the scale has been questioned regarding its latent structure, i.e., whether its items cover just one underlying construct. It has been suggested that the scale's first three items might identify emergence delirium better than the last two.

Aim: The aim of this study was to evaluate the measurement properties of the Pediatric Anesthesia Emergence Delirium scale with a focus on its latent structure and cutoff scores, using appropriate statistical methods for ordinal data.

Methods: A total of 350 children under 7 years of age, undergoing adenoidectomy, with or without additional tonsillotomy or minor procedures like paracentesis, tongue-tie release, or cerumen removal, were enrolled in the study. At the recovery unit, emergence delirium and pain were registered.

Results: The confirmatory factor analyses demonstrated that the two-factor model, including emergence delirium-specific behaviors (first three items) and emergence delirium-nonspecific behaviors (last two items), established an excellent model fit according to the χ² goodness-of-fit statistics, Root Mean Square Error of Approximation, Comparative Fit Index, Tucker-Lewis Index, and Standardized Root Mean Square Residual. The ordinal alpha of 0.98 and the ordinal omega of 0.96 supported the internal consistency reliability of the emergence delirium-specific behaviors. The convergent validity was supported due to a strong correlation between emergence delirium-nonspecific behaviors and the Face, Legs, Activity, Cry, and Consolability scale. The receiver-operating characteristic curve analyses resulted in two tentative cutoff scores for emergence delirium-specific behaviors¸ ≥ 6 and ≥ 8.

Conclusion: The Pediatric Anesthesia Emergence Delirium scale's first three items are a more valid and reliable measure of emergence delirium than its original five items.

Enhanced recovery after surgery (ERAS) pathways have been shown to improve patient outcomes, increase patient satisfaction, and decrease costs. First created and implemented in the adult population, these pathways are now commonplace and continue to expand in the pediatric realm. While there are many proven benefits to ERAS pathways, there continue to be challenges to their proper implementation and long-term success. This article aims to explore common challenges in pediatric ERAS development and implementation, along with strategies to avoid potential pitfalls. Key themes include departmental and institutional support, stakeholder engagement, awareness of pathways, data management and dissemination, and long-term maintenance including Plan-Do-Study-Act (PDSA) cycles. Pathway development teams should be aware of these considerations and potential pitfalls, and focusing on them can promote long-term success for a well-designed pathway.

Endotracheal tubes (ETTs) are life-supporting devices that are designed to maintain a patent airway in patients who are unable to sustain an airway due to illness or injury. Patients with small airways, such as neonates and pediatrics, have unique structural and functional features, making it essential that ETT design considers and executes on these particular needs. Though uncuffed ETTs have historically been preferred for patients younger than eight years of age, advances in cuffed ETT design and construction can be utilized to manufacture ETTs that are optimized for the smallest, most fragile airways. The purpose of this article is to discuss certain design features of cuffed ETTs in respect to small airways.

Background: Comprehensive data on pediatric anesthesia outcomes, particularly severe critical events (SCEs), are scarce in Asia. This highlights the need for standardized research to assess anesthesia safety and quality in the diverse settings.

Aims: The PEACH in Asia pilot study aimed to test the feasibility of a standardized protocol for investigating SCEs in anesthesia practices across Asia, evaluate the data acquisition processes, and determine the sample size for a main study.

Methods: This multicenter pilot study involved ten institutions across nine Asian countries, including children from birth to 15 years undergoing diagnostic or surgical procedures. Data on SCEs were collected using standardized definitions. The study assessed the feasibility and estimated the sample size needed for the main study.

Results: The pilot study enrolled 330 patients, with a SCE incidence of 12.4% (95% CI: 9.2-16.4%). Respiratory events were observed in 7.0% of cases, cardiovascular instability in 4.9%, and drug errors in 0.6%. Based on the SCE incidence observed in the pilot study, the estimated sample size required for the main study is at least 10 958 patients. The pilot study demonstrated the feasibility of the study protocol but identified several challenges, particularly in resource-limited settings. These challenges included a significant burden associated with data collection, technical issues with electronic case report forms (e-CRFs), variability in patient enrollment across institutions (ranging from 4 to 86 patients per site), and incomplete data acquisition (24.8% of height data and 9.7% of disposition data were missing).

Conclusions: The PEACH in Asia pilot study successfully validated a protocol for investigating SCEs in pediatric anesthesia across Asia. Addressing the challenges identified in the pilot study will be crucial for generating robust data to improve pediatric anesthesia safety in the region. Key issues to address include improving data collection methods, resolving e-CRF technical difficulties, and ensuring consistent institutional support.

Background: Despite known disparities in pediatric perioperative outcomes, few studies have examined factors associated with the use of regional anesthesia for pediatric orthopedic surgery.

Aims: This investigation aimed to determine if minority and developmental disability status were associated with the allocation of peripheral nerve blocks in calcaneal osteotomy.

Methods: We conducted a single-center, retrospective study of records of patients <18 years who underwent calcaneal osteotomy from 2013 to 2022. Regional technique was classified into three groups: popliteal-sciatic single-shot block, popliteal-sciatic catheter, and no block. Patients were classified as either nonminority (white, non-Hispanic) or minority. Developmental disability status was defined based on medical history and classified as binary. Anesthesiologists were classified as "regional" or "nonregional" based on clinical expertise. A Bayesian hierarchical multinomial model with random intercepts for patients and surgeons was used to investigate the association of minority status, developmental disability, and anesthesiologist expertise with block selection.

Results: We analyzed 287 cases in 225 patients; of these, 55% occurred in minority patients and 28% occurred in patients with developmental disability. Catheters were placed in 45% of cases, single shot blocks in 41%, and no block in 14%. Minority and nonminority patients had a similar likelihood of receiving of any block. Patients with developmental disability had a -22% absolute difference of receiving any block (95% credible interval [-38%, -7%]) compared to those without developmental disability (55% vs. 77%), an effect primarily driven by a lower rate of catheter placement in these children. Regional anesthesiologists were more likely to place catheters (23% absolute increase; 36% vs. 13%) and more likely to perform any block in children with developmental disability (30% absolute increase; 67% vs. 37%) than nonregional anesthesiologists.

Conclusions: Decision-making surrounding the placement of regional anesthesia techniques is complex. In this study, developmental disability status and anesthesiologist experience were associated with a difference in the use of regional anesthesia in patients undergoing calcaneal osteotomy.

Background: Connecting an infusion line to a closed stopcock results in pressurization of fluid within the syringe infusion pump assembly leading to flow irregularities when opening the stopcock and activating the pump.

Aims: It was the purpose of this study to assess the extent of pressurization under different conditions and its impact on start-up fluid delivery.

Methods: Intraluminal pressures and start-up fluid delivery at 1 mL/h flow rate were assessed with connection of the infusion line 1 min (delayed connection) or immediately after purging (immediate connection) using two different infusion lines made from polyvinylchloride (PVC) or polyethylene (PE).

Results: Delayed connection resulted in an increase of intraluminal pressures from zero to 5.1 [4.5 to 5.7] mmHg with the PVC line and from zero to 47.1 [44.8 to 49.3] mmHg with the PE line (mean difference 42.0 [95% CI 39.3-44.7] mmHg; p < .0001). Immediate connection resulted in an increase of intraluminal pressures from zero to 44.3 [41.8-46.8] mmHg with the PVC line and from zero to 61.3 [57.2-65.4] mmHg with the PE line (mean difference 17.0 [95% CI 11.8-22.2] mmHg; p < .0001). The increase in intraluminal pressures was significantly higher with PE lines for both delayed and immediate connection when compared to the PVC lines (mean difference 29.5 [95% CI 19.3-39.7] mmHg; p < .0001). Related fluid volumes delivered at 10 s and 360 s after starting the pump ranged from -252% to 1321% (10 s) of expected infusion volumes and from 59% to 129% (360 s), respectively.

Conclusions: Both, timing of infusion line connection after purging and infusion line characteristics considerably affect intraluminal pressures and start-up fluid delivery when connecting a new syringe infusion pump assembly to a closed stopcock. Consecutive alterations in drug administration can have considerable hemodynamic consequences when dealing with catecholamine infusions in critically ill patients.
