ABSTRACT
La metahemoglobinemia es un síndrome clínico que se produce por la oxidación del hierro de la hemoglobina impidiendo su adecuada unión al oxígeno, de forma que existe dificultad por parte de los glóbulos rojos tanto para captar el oxígeno, como para cederlo a los tejidos ocasionando hipoxia tisular. Describimos el caso de una paciente que presentó síntomas neurológicos y metahemoglobinemia como reacción adversa por contacto con crema de anestésico tópico (EMLA)
Methemoglobinemia is a clinical syndrome secondary to the oxidation of iron in hemoglobin, preventing its adequate binding to oxygen. Subsequently, red blood cells are unable to appropriately capture oxygen and deliver it to the tissues, causing hypoxia. We describe a case of a patient who presented neurological symptoms in the context of methemoglobinemia as an adverse reaction to the administration of EMLA

Acute spinal cord infarct in childhood is extremely rare, generally secondary to spinal/cardiovascular surgery or severe vertebral injuries. However, spontaneous spinal cord infarct cases have been described. We present a clinical case of a teenager who developed an acute weakness and paraesthesia in lower limbs after playing piggyback. Laboratory tests and MRI (magnetic resonance imaging) were normal. During her hospital admission, her motor strength improved. After 10 days, MRI was repeated, and a bone infarct was observed. She was medicated with acetylsalicylic acid, and she completed a rehabilitation program.
ABSTRACT
Percutaneous cardiac intervention is an invasive diagnostic and therapeutic technique which carries a significant complication rate. Although the usefulness of EFAST protocol is widely recognised, this paper will attempt to explore a modified approach involving a focused examination on the retroperitoneal (r-EFAST). We have provided examples of 3 cases where r-EFAST was used to detect retroperitoneal bleeding in critical situations.
