Randomized Controlled TrialPreoperative anxiety in preschool children: A randomized clinical trial comparing midazolam, clonidine, and dexmedetomidine.
Anxiety in pediatric patients may challenge perioperative anesthesiology management and worsen postoperative outcomes. Sedative drugs aimed to reducing anxiety are available with different pharmacologic profiles, and there is no consensus on their effect or the best option for preschool children. In this study, we aimed to compare the effect of three different premedications on anxiety before anesthesia induction in preschool children aged 2-6 years scheduled for elective surgery. The secondary outcomes comprised distress during peripheral catheter (PVC) insertion, compliance at anesthesia induction, and level of sedation. ⋯ In preschool children, midazolam resulted in a more effective anxiolysis and less sedation compared to clonidine and dexmedetomidine.

ReviewPerioperative anesthesia care for the pediatric patient undergoing a kidney transplantation: an educational review.
Living-donor kidney transplantation is the first choice therapy for children with end-stage renal disease and shows good long-term outcome. Etiology of renal failure, co-morbidities, and hemodynamic effects, due to donor-recipient size mismatch, differs significantly from those in adult patients. Despite the complexities related to both patient and surgery, there is a lack of evidence-based anesthesia guidelines for pediatric kidney transplantation. This educational review summarizes the pathophysiological changes to consider and suggests recommendations for perioperative anesthesia care, based on recent research papers.

Randomized Controlled TrialGastric emptying time of two different quantities of clear fluids in children: a double blinded randomised controlled study.
Perioperative pulmonary aspiration risk increases with increased preoperative gastric volume; hence traditionally, healthy children are kept fasted overnight before surgery. Current guidelines recommend 2-h clear fluids fasting prior to anesthesia. However, emerging evidence favors allowing 3 ml/kg clear fluids up to 1-h before anesthesia. We compared the gastric volume and gastric emptying time after ingestion of 3 ml/kg and 5 ml/kg of clear fluids. ⋯ As the gastric volume returned to baseline within 1-h even after ingesting 5 ml/kg clear fluids, the preoperative fasting time can be reduced to 1-h and healthy children undergoing elective procedure can be safely allowed to drink up to 5 ml/kg clear fluids.

Case ReportsTwin-Twin Transfusion Syndrome Complicated by Single Ventricle Physiology: A Case Report.
Clinically significant extrauterine twin-twin transfusion syndrome in conjoined twins is rare and carries a high risk of perinatal mortality. The ensuing postnatal imbalance in circulation across connecting vessels results in hypovolemia in the donor and hypervolemia in the recipient. Data on management and treatment are sparse especially in the setting of a single ventricle congenital heart defect. ⋯ The resulting pathophysiology in the setting of a single ventricle congenital heart defect created added layers of complexity to their management and expedited surgical separation. Shunting from Twin B to Twin A-with an anatomically normal heart-resulted in mal-perfusion and rapid deterioration jeopardizing the health of both twins. In the preoperative course, steps taken to medically optimize the twins prior to surgery and the anesthetic considerations are detailed in this report.

Dimensional compatibility of rigid ventilating bronchoscopes with pediatric airway anatomy using different recommendations for age-related sizing - A bench study.
Appropriate size selection of pediatric rigid bronchoscopes is fundamental to avoidance of airway trauma and to a high success rate with the first intubation attempt. The aim of the present study was to compare the outer diameters of pediatric rigid bronchoscopes with the anatomical data on the pediatric airway. ⋯ Based on this in vitro study, most of the recommendations analyzed result in a balanced fit of rigid bronchoscopes within the cricoid. Since the left mainstem bronchus is considerably smaller than the cricoid, any insertion on this level will require careful endoscopic guidance to avoid damage to the left mainstem bronchus.
