Hemodynamic profile effects of PM101 amiodarone formulation in patients with post-operative tachyarrhythmias.

Amiodarone may be considered for patients with junctional ectopic tachycardia refractory to treatment with sedation, analgesia, cooling, and electrolyte replacements. There are currently no published pediatric data regarding the hemodynamic effects of the newer amiodarone formulation, PM101, devoid of hypotensive agents used in the original amiodarone formulation. We performed a single-center, retrospective, descriptive study from January 2012 to December 2020 in a pediatric ICU. Thirty-three patients were included (22 male and 11 female) between the ages of 1.1 and 1,460 days who developed post-operative junctional ectopic tachycardia or other tachyarrhythmias requiring PM101. Data analysis was performed on hemodynamic parameters (mean arterial pressures and heart rate) and total PM101 (mg/kg) from hour 0 of amiodarone administration to hour 72. Adverse outcomes were defined as Vasoactive-Inotropic Score >20, patients requiring ECMO or CPR, or patient death. There was no statistically significant decrease in mean arterial pressures within the 6 hours of PM101 administration (p > 0.05), but there was a statistically significant therapeutic decrease in heart rate for resolution of tachyarrhythmia (p < 0.05). Patients received up to 25 mg/kg in an 8-hour time for rate control. Average rate control was achieved within 11.91 hours and average rhythm control within 62 hours. There were four adverse events around the time of PM101 administration, with three determined to not be associated with the medication. PM101 is safe and effective in the pediatric cardiac surgical population. Our study demonstrated that PM101 can be used in a more aggressive dosing regimen than previously reported in pediatric literature with the prior formulation.

Supporting and Contextualizing Pediatric ECMO Decision-Making Using a Person-Centered Framework.

AbstractThere is a critical need to establish a space to engage in careful deliberation amid exciting, important, necessary, and groundbreaking technological and clinical advances in pediatric medicine. Extracorporeal membrane oxygenation (ECMO) is one such technology that began in pediatric settings nearly 50 years ago. And while not void of medical and ethical examination, both the symbolic progression of medicine that ECMO embodies and its multidimensional challenges to patient care require more than an intellectual exercise. What we illustrate, then, is a person-centered framework that incorporates the philosophy and practice of palliative care and care-based ethical approaches. This person-centered framework is valuable for identifying and understanding challenges central to ECMO, guides collaborative decision-making, and recognizes the value of relationships within and between patients, families, healthcare teams, and others who impact and are impacted by ECMO. Specifically, this person-centered approach enables caregivers to provide compassionate and effective support in critical, and often urgent, situations where conflicts may emerge among healthcare team members, families, and other decision makers. By reflecting on three cases based on actual situations, we apply our person-centered framework and identify those aspects that were utilized in and informed this project. We aim to fill a current gap in the pediatric ECMO literature by presenting a person-centered framework that promotes caregiving relationships among hospitalized critically ill children, families, and the healthcare team and is supported through the philosophy and practice of palliative care and clinical ethics.

Brimonidine Toxicity Secondary to Topical Use for an Ulcerated Hemangioma.

Combigan (Allergan, Irvine, CA) is an ophthalmic solution that combines 0.2% brimonidine, a selective α-2 adrenergic agonist, with 0.5% timolol, a nonselective ß-adrenergic antagonist. It is approved for the reduction of intraocular pressure in patients with glaucoma or ocular hypertension. There have been recent reports of successful treatment of superficial infantile hemangiomas (IHs) using Combigan topically. We report the case of a 2-month-old girl who developed life-threatening brimonidine toxicity requiring intubation and mechanical ventilation secondary to central nervous system depression and apnea after topical application to an ulcerated IH.

Intracranial pressure/cerebral perfusion pressure-targeted management of life-threatening intracranial hypertension complicating diabetic ketoacidosis-associated cerebral edema: a case report.

Symptomatic cerebral edema from diabetic ketoacidosis occurs infrequently but carries a high rate of mortality and morbidity owing to complications from intracranial hypertension. Treatment options are limited but include hyperosmolar therapy with mannitol or hypertonic saline, tracheal intubation for airway protection, and hyperventilation via mechanical ventilation. We describe here the successful use of an intracranial pressure/cerebral perfusion pressure-targeted management strategy through ventriculostomy catheter placement with intracranial pressure monitoring and cerebrospinal fluid drainage, hyperosmolar therapy with hypertonic saline, and controlled hyperventilation to treat life-threatening complications of cerebral edema in a pediatric patient with severe diabetic ketoacidosis.

A normal capillary refill time of ≤ 2 seconds is associated with superior vena cava oxygen saturations of ≥ 70%.

OBJECTIVE: To test the hypothesis that a normal capillary refill time (CRT) ≤ 2 seconds is associated with superior vena cava oxygen saturation (ScvO2) ≥ 70% in critically ill children. STUDY DESIGN: Two-year, prospective study in a tertiary-level pediatric intensive care unit. Whenever ScvO2 measurements were obtained, central (forehead/sternum) and peripheral (finger/toe) CRTs were concomitantly assessed. RESULTS: Central and peripheral CRTs ≤ 2 seconds were both associated with ScvO2 ≥ 70% (P < .01). Sensitivity/specificity analyses revealed that central CRT ≤ 2 seconds demonstrated a sensitivity of 84.4%, specificity of 71.4%, positive predictive value of 93.1%, and negative predictive value of 50.0% in predicting ScvO2 ≥ 70%. Peripheral CRT ≤ 2 seconds had a sensitivity of 71.9%, specificity of 85.7%, positive predictive value of 95.8%, and negative predictive value of 40.0% in predicting ScvO2 ≥ 70%. CONCLUSIONS: A normal CRT ≤ 2 seconds can be predictive of ScvO2 ≥ 70%. Our study corroborates the recommendations of the Pediatric Advanced Life Support curricula targeting a normal CRT ≤ 2 seconds as a therapeutic endpoint for goal-directed shock resuscitation. This clinical target remains particularly relevant in community hospitals when the ability to obtain central venous catheter access may be limited and ScvO2 data unavailable.
