A retrospective cohort study of predictors and interventions that influence cooperation with mask induction in children.

BACKGROUND: Uncooperative pediatric mask induction is linked to perioperative anxiety. Although some risk factors for uncooperative inductions have been reported, there are no large cohort studies that identify intrinsic patient characteristics associated with cooperation. AIM: The primary aim was to identify patient characteristics associated with cooperative mask inductions. The secondary aim was to determine whether preoperative interventions were associated with increased cooperation. METHODS: This retrospective cohort study included patients 2-11 years old and ASA class I-IV who underwent mask induction. Our primary outcome of interest was cooperation with mask induction, which was correlated against the Induction Compliance Checklist. The variables analyzed for association with cooperation were age, sex, ASA class, class of surgery, preferred language, and race. Interventions examined for association with induction cooperation included premedication with midazolam, exposure to distraction technology, parental presence, and the presence of a Child Life Specialist. Multivariate mixed-effects logistic regression was used to assess the relationship between patient characteristics and cooperation. A separate multivariate mixed-effects logistic regression was used to examine the association between preoperative interventions and cooperation. RESULTS: 9692 patients underwent 23 474 procedures during the study period. 3372 patients undergoing 5980 procedures met inclusion criteria. The only patient characteristic associated with increased cooperation was age (OR 1.20, p-value 0.03). Involvement of Child Life Specialists was associated with increased cooperation (OR 4.44, p-value = 0.048) while parental/guardian presence was associated with decreased cooperation (OR 0.38, p-value = 0.002). CONCLUSION: In this cohort, increasing age was the only patient characteristic found to be associated with increased cooperation with mask induction. Preoperative intervention by a Child Life Specialists was the sole intervention associated with improved cooperation.

Operating Room Codes Redefined: A Highly Reliable Model Integrating the Core Hospital Code Team.

INTRODUCTION: Typically, multidisciplinary teams manage cardiac arrests occurring outside of the operating room (OR). This approach results in reduced morbidity. However, arrests that occur in the OR are usually managed by OR personnel alone, missing the benefits of out-of-OR hospital code teams. At our institution, there were multiple pathways to activate codes, each having different respondents, depending on time and day of the week. This improvement initiative aimed to create a reliable intraoperative emergency response system with standardized respondents and predefined roles. METHODS: A multidisciplinary improvement team led this project at an academic pediatric hospital in California. After simulations performed in the OR (in situ), the team identified a valuable key driver-a consistent activation process that initiated standard respondents, 24 hours a day, 7 days a week. By utilizing core hospital code members routinely available outside of the OR during days, nights, and weekends, respondents were identified to augment OR personnel. Code roles were preassigned. After education, we conducted in situ simulations that included the perioperative and out-of-OR code team members. We administered a knowledge assessment to perioperative staff. RESULTS: The knowledge assessment for perioperative staff (n = 52) had an average score of 96%. Review of subsequent OR codes reflects an improved initiation process and management. CONCLUSIONS: The process for activating the emergency response system and roles for intraoperative code respondents were standardized to ensure a predictable code response, regardless of time or day of the week. Ongoing simulations with perioperative personnel continue to optimize the process.

Differential Lung Ventilation Using a Bronchial Blocker in a Pediatric Patient on Extracorporeal Membrane Oxygenation: A Case Report.

We describe a patient with acute on chronic respiratory failure after a cardiac arrest who was cannulated to venoarterial extracorporeal membrane oxygenation. The patient developed right-sided interstitial emphysema with air leak and left-sided hemothorax with secondary atelectasis. A differential lung ventilation strategy was used in which an endotracheal tube was placed in the left main stem bronchus and a bronchial blocker was placed in the right mainstem bronchus. The patient's overall pulmonary function improved, and he was successfully decannulated from extracorporeal membrane oxygenation. In conclusion, differential lung ventilation may be performed in patients on extracorporeal membrane oxygenation with disparate lung disease as an alternative ventilation strategy.

Practical Regional Anesthesia Guide for Elderly Patients.

Ultrasound-guided regional anesthesia is an important part of the practice of anesthesia for the elderly population, the growth of which will continue to outpace that of the younger population due to improvements in lifespan worldwide. The elderly patient is uniquely vulnerable to the effects of systemic anesthetic drugs, and our understanding of the potential toxicities that general anesthetics can have on the elderly brain and body continues to evolve. Aging impacts both the pharmacokinetics and pharmacodynamics of sedative medications and local anesthetics. Alongside the physiologic aging process often comes a myriad of pathologic co-morbidities that can accumulate with age, and result in a great variability of physiologic reserve. This variability in overall functional status is described by a newer concept termed 'frailty,' which is used to evaluate and risk-stratify elderly patients perioperatively. The choice for regional anesthesia is based on a combination of factors such as duration of surgery, pre-existing patient risk factors, and the skill and technique of the anesthesiologist. The utilization of preoperative and intraoperative sedation is now recognized as a key component in maximizing the safety and success rate of regional anesthesia. Excellent pain management with minimal to no sedation during the operation may have benefits that extend far beyond the immediate perioperative setting. Regional anesthesia is increasingly integrated as an important part of multimodal enhanced recovery after surgery (ERAS) protocols, which aim to decrease the cost, enhance safety, and improve the patient's subjective experience during and after hospitalization. Ultrasound-guided techniques, recently developed regional blocks, medications for sedation, and local anesthetics are reviewed in this article.
