The Critically Ill Infant: THE MISFITS
Trauma
* ‘T’ in the mnemonic stands for trauma, which includes both accidental and intentional causes.
* Considerations for Non-accidental Trauma:
* Stresses the importance of considering non-accidental trauma, especially given that it may not always present with obvious external signs.
* Anatomical Vulnerabilities:
* Highlights specific anatomical considerations for infants who suffer from trauma:
* Infants have proportionally larger heads, increasing their susceptibility to high cervical spine (c-spine) injuries.
* Their liver and spleen are less protected, making abdominal injuries potentially more severe.
Heart
* 5 T’s of Cyanotic Congenital Heart Disease: Introduces a mnemonic to help remember key right-sided ductal-dependent lesions:
* Truncus Arteriosus: Single vessel serving as both pulmonary and systemic outflow tract.
* Transposition of the Great Arteries: The pulmonary artery and aorta are switched, leading to improper circulation.
* Tricuspid Atresia: Absence of the tricuspid valve, leading to inadequate development of the right ventricle and pulmonary circulation issues.
* Tetralogy of Fallot: Comprises four defects—ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta.
* Total Anomalous Pulmonary Venous Connection (TAPVC): Pulmonary veins do not connect to the left atrium but rather to the right heart or veins, causing oxygen-rich blood to mix with oxygen-poor blood.
* Other Significant Conditions:
* Ebstein’s Anomaly: Malformation of the tricuspid valve affecting right-sided heart function.
* Pulmonary Atresia/Stenosis: Incomplete formation or narrowing of the pulmonary valve obstructs blood flow to the lungs.
* Left-sided Ductal-Dependent Lesions:
* Conditions such as aortic arch abnormalities (coarctation or interrupted arch), critical aortic stenosis, and hypoplastic left heart syndrome are highlighted. These generally present with less obvious cyanosis and more pallor.
* Diagnostic and Management Considerations:
* Routine prenatal ultrasounds detect most cases, but conditions like coarctation of the aorta and TAPVC might not be apparent until after birth when the ductus arteriosus closes.
* Emphasizes the importance of a thorough physical exam: checking for murmurs, assessing hepatosplenomegaly, feeling for femoral pulses, measuring pre- and post-ductal saturations,
