Background:Advancements in palliative surgery of patients with single ventricle physiology have led to an increase in the need for deep sedation protocols for painful procedures. However, positive pressure ventilation during anesthesia can result in unfavorable cardiopulmonary interactions. This patient population may benefit from sedation from these painful procedures. Methods:This study aims to demonstrate the safety and efficacy of deep sedation by pediatric intensivists outside the operating room for children with single ventricle physiology. This is a single-center, retrospective chart review on consecutive pediatric patients with single ventricle physiology who received deep sedation performed by pediatric intensivists between 2013 and 2020. Results:Thirty-three sedations were performed on 27 unique patients. The median age was 3.7 years (25th%-75th%: 2.1-15.6). The majority of the sedations, 88% (29/33), were done on children with Fontan physiology and 12% (4/33) were status-post superior cavopulmonary anastomosis. The primary cardiac defect was hypoplastic left heart in 63% (17/27) of all sedation procedures. There were 24 chest tube placements and 9 cardioversions. Ketamine alone [median dose 1.5 mg/kg (range 0.8-3.7)], ketamine [median dose 1 mg/kg (range 0.1-2.1)] with propofol [median dose 2.3 mg/kg (range 0.7-3.8)], and ketamine [median dose 1.5 mg/kg (range 0.4-3.0)] with morphine [median dose 0.06 mg/kg (range 0.03-0.20)] were the most common sedation regimens used. Adverse events (AEs) occurred in 4 patients (15%), three of which were transient AEs. All sedation encounters were successfully completed. Conclusion:Procedural deep sedation can be safely and effectively administered to single ventricle patients by intensivist-led sedation teams in selective case.

Background Pain control following cardiac surgery can be challenging, and inadequate pain control is associated with postoperative complications. Liposomal bupivacaine can improve postoperative pain control due to its prolonged duration compared with plain bupivacaine. However, there is a paucity of data regarding its efficacy in congenital cardiac surgery. The primary outcome was to compare opioid requirements between liposomal bupivacaine and plain bupivacaine for local infiltration in pediatric patients undergoing cardiac surgical procedures via a median sternotomy approach. Secondary outcomes included antiemetic use, adjunct pain medication use, length of stay, and pain scores.Methods This single center retrospective study analyzed data from 2017 to 2022 involving patients who underwent congenital cardiac surgery via median sternotomy. Sixty-three patients who received liposomal bupivacaine were matched with 33 patients who received plain bupivacaine. Patient data were extracted from the electronic medical record and underwent statistical analysis using Wilcoxon, χ2, and Fisher exact tests.Results There were no demographic differences between the two groups. Postoperative opioid use did not differ significantly between the liposomal bupivacaine and plain bupivacaine groups. The liposomal bupivacaine group had increased acetaminophen and antiemetic use, while the plain bupivacaine group had increased ketorolac use. Otherwise, there were no significant differences in secondary outcomes, including length of stay.Conclusion Liposomal bupivacaine may not offer any advantage over plain bupivacaine in congenital cardiac postoperative pain control.

The management of hypoplastic left heart syndrome (HLHS) has changed substantially over the past four decades. In the 1970s, children with HLHS could only be provided with supportive care. As a result, most of these unfortunate children died within the neonatal period. The advent of the Norwood procedure in the early 1980s has changed the prognosis for these children, and the majority now undergoing a series of three surgical stages that can support survival beyond the neonatal period and into early adulthood. This review will focus on the Norwood procedure and the other important innovations of the last half century that have improved our outlook toward children born with HLHS.

We describe two pediatric patients with Duchenne muscular dystrophy that presented with acute neurologic deterioration and hypoxic respiratory failure requiring mechanical ventilation. These cases fulfill the clinical criteria for Fat Embolism Syndrome. Early recognition and aggressive supportive therapy with mechanical ventilation, right ventricular afterload reduction, and blood transfusion led to survival without any residual effects from the event. Fat Embolism Syndrome needs to be considered early in the course of patients with Duchenne muscular dystrophy who present with respiratory and neurological symptoms.
