An approach to using pharmacokinetics and electroencephalographyforpropofol anesthesia for surgery in infants.
Safe and effective techniques for propofol total intravenous anesthesia (TIVA) in infants are not well imbedded into clinical practice, resulting in practitioner unfamiliarity and potential for over- and under-dosing. In this education article, we describe our approach to TIVA dosing in infants and toddlers (birth to 36 months) which combines the use of pharmacokinetic models with EEG multi-parameter analysis. Pharmacokinetic models describe propofol and remifentanil effect site concentrations (Ce) over time in different age groups for a given dosing regimen. ⋯ In our practice, we use a "lookup table" of age-based dosing regimens or target-controlled infusion (TCI) based on the pharmacokinetic models to deliver a target propofol Ce and co-administer remifentanil and/or regional technique for analgesia. We analyze Electroencephalogram (EEG) waveforms, SEF, and DSA to adjust the propofol dose or TCI target concentration to the individual infant. EEG analysis mitigates against biological variability inherent in the pharmacokinetic models and has improved our experience with TIVA for infants.

Review Meta AnalysisEfficacy of caudal versus intravenous administration of α2 adrenoceptor agonists to prolong analgesia in pediatric caudal block: A systematic review and meta-analysis.
α2 adrenoceptor agonists have been proposed as adjuncts to prolong analgesia in pediatric caudal block. The aim of this meta-analysis was to compare the analgesic efficacy of caudal vs intravenous α2 adrenoceptor agonists during pediatric caudal block. ⋯ Caudal α2 adrenoceptor agonists as adjuncts to local anesthetic during pediatric caudal block are more effective than intravenous injection. However, the results were affected by small sample size and significant heterogeneity.

Observational StudyUltrasound assessment of gastric emptying time after intake of clear fluids in children scheduled for general anesthesia - a prospective observational study.
While many clinics have changed their local regimen toward a more liberal policy regarding clear fluid fasting for general anesthesia, there is a lack of studies evaluating gastric emptying time in a clinical setting. ⋯ This study showed that the gastric emptying time of children after intake up to 5 mL kg-1 clear fluids was <1 hour in a clinical setting. These results support the more liberal fasting regimen favoring a 1-hour fasting time and suggest 5 mL kg-1 as an upper limit for clear fluids (eg, water, sugared water or tea or diluted fruit juice) from 2 hours to 1 hour before induction of anesthesia in children.

Observational StudyRoutine Chest X-Ray Following Ultrasound-Guided Internal Jugular Veins Catheterization in Critically Ill Children: A Prospective Observational Study.
Recent studies in adults have shown that routine chest X-ray following ultrasound-guided central venous catheter insertion through the internal jugular vein is unnecessary due to a low rate of complications. ⋯ In this critically ill pediatric cohort, all central venous catheters inserted under ultrasound guidance could have been used with safety prior to acquiring chest X-ray. Overall chest X-ray impacted patient management in only 1% of cases. Our results do not support delaying urgent central venous catheter use pending chest X-ray completion in critically ill children.

Review2020 Guidelines for Conducting Plastic Reconstructive Short-Term Surgical Projects in Low-Middle Income Countries.
Many low- or middle-income countries (LMICs) continue to suffer from a lack of safe and timely essential and emergency surgery despite growing attention to this problem. Short-term surgical projects (STSPs) continue to play an important role in addressing LMIC unmet surgical need and strengthening local healthcare systems. Guidelines here present recommendations for performing plastic reconstructive STSPs for pediatric patients in a safe, ethical, and effective manner. ⋯ Host education during STSPs has become crucial as LMICs ramp up training at a time when their surgical volumes remain grossly behind well-resourced countries. Recommendations here aim to assist organizations, hosts, and volunteers as they navigate the enormously complex and ever changing STSP environment. Patient safety and transfer of knowledge and skills should be central concerns of all who participate in this highly rewarding endeavor.
