ABSTRACT

RESUMEN El edema pulmonar por presión negativa es una complicación rara y dramática en la anestesia general. Habitualmente ocurre como consecuencia de un laringoespasmo u otra causa de obstrucción de la vía aérea. Se presentó un caso con el objetivo de mostrar los elementos usados para el diagnóstico y tratamiento del edema pulmonar por presión negativa. Paciente de 7 años de edad, femenina, ASA I, operada de metatarso varo funcional con anestesia general balanceada y máscara laríngea clásica # 3. Desarrolló dicho evento adverso durante la recuperación anestésica. El diagnóstico se basó en la disociación toraco abdominal al restablecer la ventilación espontanea, crepitantes en ambos hemitórax, cianosis central, hipoxemia y la presencia de infiltrado difuso bilateral alveolar. Se intubó la tráquea, se controló la ventilación con presión positiva al final de la espiración y se administró furosemida. La paciente fue trasladada a la Unidad de Cuidados Intensivos donde evolucionó satisfactoriamente. Este es un síndrome cuya verdadera incidencia se desconoce debido a la escasa familiarización con el mismo. La evolución de los pacientes es favorable siempre que se establezca el diagnóstico y el tratamiento oportuno (AU).


ABSTRACT Pulmonary edema due to negative pressure is a rare and dramatic complication in general anesthetic. It usually occurs as a consequence of a laryngeal spasm or another cause of respiratory tract obstruction.A case was presented with the aim of showing the elements used for the diagnosis and treatment of the pulmonary edema due to negative pressure. An ASA I, 7-year-old female patient, was operated on a functional metatarsus varus with balanced general anesthetic and classical laryngeal mask number 3. She developed this adverse event during the anesthetic recovery. The diagnosis was based on the thoracoabdominal dissociation when recovering spontaneous ventilation, crepitation in hemithoraxes, central cyanosis, hypoxemia, and alveolar bilateral diffused infiltrate. The trachea was intubated, ventilation was controlled with positive pressure at the end of the expiration and furosemide was administered. The patient was transferred to the Intensive Care Unit where she evolved satisfactorily. This is a syndrome whose true incidence is unknown as a result of the lack of familiarization with it. Patients' evolution is favorable whenever the right diagnosis and treatment are timely established (AU).

ABSTRACT

Negative Pressure Pulmonary Edema [NPPE] or Post-Obstructive Pulmonary Edema [POPE] is one of the most life-threatening emergencies in anesthesia


Immediate diagnosis with NPPE leads to better outcome. Usually, it affects healthy young patients. It occurs after upper airway obstruction, such as laryngeal spasms, tumor, and infection; it follows strong inspiratory effort leading to low negative pressure in the lungs which results into fluid infiltration and precipitates interstitial and alveolar edema


We report a case of unusual presentation of Negative Pressure Pulmonary Edema during and after extubation, which highlights the importance of early recognition and timely intervention to prevent further deterioration

ABSTRACT

O objetivo deste trabalho foi verificar o efeito das manobras de pressäo negativa (MPN) e compará-la com a sustentaçäo máxima da inspiraçäo (SMI) em pacientes que apresentam diminuiçäo da capacidade vital (CV). Foram estudados 5 pacientes paraplégicos do sexo masculino, com lesäo nível T2-T6, há no mínimo 1 ano e com ausência de patologias pulmonares. Cada participante foi submetido a MPN e SMI aleatoriamente em diferentes dias. Antes e após a terapia foi realizada a espirometria e a mensuraçäo da frequência respiratória e durante a terapia foi registrada a saturaçäo de oxigênio (SatO2) e frequência cardíaca. Na MPN foram realizadas 3 séries de 15 repetiçöes. Todas as técnicas foram feitas com o indíviduo na posiçäo sentada, com duraçäo média de 15 minutos. Os pacientes submetidos a MPN näo apresentaram diferenças espirométricas significativas, porém os pacientes submetidos a SMI apresentaram aumento do volume de reserva inspiratório (VRI), queda do volume de reserva expiratório (VRE), queda do volume corrente (VC) e queda do fluxo inspiratório (VC/Ti). A SatO2 näo variou durante as terapias. A SMI mostrou-se mais efetiva do que a MPN em pacientes com reduçäo da CV.
