[Massive pulmonary hemorrhage in surgical pathology of the newborn infant]. / La hemorragia pulmonar masiva en la patología quirúrgica del recién nacido.

Massive pulmonary hemorrhage is a complication which frequently leads to death in newborns with conditions susceptible to surgical treatment. Out of 112 postmortem studies, focal hemorrhage was found in 38 (33.9%) and massive in 34 cases (30.3%). In this series, congenital anomalies were found in digestive tract in 70.5% of the patients. Prematurity andlow weight were not important factors as was hypoxia, which was evident in 70.5% of the cases. Manifestations of respiratory insufficiency, shock, rales in lung fields, bleeding in other places different from the lung, blood leaking through upper respiratory ducts, are all clinical features of diagnostic aid. Disturbances in coagulation tests were detected, the same as drop in figures of hemoglobin, acidosis, hypoxia and hypercapnia. Gram-negative germs, with a predominance of Klebsiella, were isolated in 33 cultures. The radiographic finding with reticulogranular image was unfrequent. Among other precipitating factors of pulmonary hemorrhage, identification was made of the surgical disease by itself, surgical and anesthetic procedures, of ventilatory assistance and therapy with oxygen at high concentration for long periods of time.

Efecto del salbutamol sobre la dinámica cardiorrespiratoria en pacientes asmáticos / Effect of the albuterol on the heart respiratory dinamic in asmatic patients

Se realiza una investigación prospectiva,por corte transversal y descriptiva, con pacvientes procedentes de las consultas de Neumología y Alergia del HGD "Dr. Agostinho Neto" de la provincia de Gtmo, en el período comprendido entre octubre de 1988 y abril de 1989, ambos incluidos. El universo de trabajo estuvo compuesto por 16 pacientes asmáticos, sin otro padecimiento crónico y en período de intercrisis, 8 del sexo femenino y 8 del masculino, comprendidos entre las edades de 15 a 21 años. La experiencia consistió en el registro de electrocardiograma en la primera derivación standard -D1-durante la respiración normal y realización de las maniobras respiratorias de apnea e hiperventilación, antes y después de administrarles Salbutamol; los cuales fueron utilizados para realizar la valoración del estado neurovegetativo y el comportamiento del ritmo sinusual. Por la acción del medicamento aparece una tendencia al predominio de la actividad simpática y la estabilización del ritmo sinusual
