ABSTRACT

Objetivos: Evaluar la experiencia del Servicio de Cirugía de Tórax del Hospital Universitario de Maracaibo en el diagnóstico y tratamiento del neumotórax en el recién nacido. Métodos: 23 recién nacidos con neumotórax fueron evaluados por el Servicio de Cirugía de Tórax en la Emergencia Pediátrica, Unidad de Cuidados Intensivos Pediátricos y en el Servicio de Neonatología entre los años 2000–2004. Se recolectaron los datos relacionados con: la duración de la gestación, complicaciones maternas durante el embarazo, examen físico, estudios diagnósticos, tratamiento yevolución de los pacientes. Resultados: 13(56.52%) delos recién nacidos eran varones y la edad gestacional promedio fue de 35.25 +/- 2.49 semanas. 12(52.17%) nacieron por cesárea y 10(43.47%) tenían antecedentes de maniobras de reanimación al nacer. El neumotórax se localizó en el hemitórax izquierdo en 8 recién nacidos (34.78%), hemitórax derecho en 14 recién nacidos (60.86%) y en ambos hemitórax en 1 recién nacido (4.47%). 22 (95.65%) presentaron dificultad respiratoria El tratamiento incluyó una conducta expectante en 2 recién nacidos con neumotórax menor de 25%, y la colocación de tubo de toracostomía en 21 recién nacidos (91.30%) con neumotórax mayor de 25% Conclusión: el neumotórax es una complicación que se observa principalmente en el recién nacido con Apgar bajo al nacer o querequieren maniobras de reanimación y se presenta con dificultad respiratoria. Los neumotorax menores de 25% pueden manejarse con observación y radiología seriada, pero aquellos mayores de 25% requerirán colocación de tubo de toracostomía.


Objectives: To evaluate the experience of Thoracic Surgery Service in the diagnosis and treatment of pneumothorax in newborn at theHospital Universitario de Maracaibo.Methods: 23 newborn with pneumothorax were evaluated by the Thoracic Surgery Service in the Pediatric Emergency Unit, PediatricIntensive Care Unit and Neonatology Service between the years 2000-2004. Data was collected regarding gestational age, complications during the pregnancy, physical exam, diagnostic studies, treatment and evolution of the patients. Results: 13 (56.52%) were males, with mean gestational age of 35 +/- 2.5 weeks. 12 (52.17%) were born by caesarean section and 11(47.82%) by vaginal delivery. 10 newborns had history of resuscitation manoeuvres (43.47%). Pneumothorax was located in lefthemithorax in 8 newborn (34.78%), right hemithorax in 14 newborn (60.86%) and both hemithorax in 1 newborn (4.47%). 22 (95.65%)presented respiratory distress. Treatment included observation in 2 newborns with pneumothorax < 25%, and tube thoracostomy in 21 (91.30%) with pneumothorax > 25%. Conclusion: Pneumothorax is a complication seen mainly in newborns with low Apgar score and those who required resuscitation manoeuvres and almost always presents with respiratory distress. Pneumothorax < 25% can be treated with observation and serialradiology but those > 25%.will require tube thoracostomy.

ABSTRACT

El Síndrome de Dificultad Respiratoria constituye una de las afecciones más frecuentes en el recién nacido y se comporta como uno de los principales indicadores de morbilidad y mortalidad. Con el objetivo de caracterizar las causas más frecuentes de dificultad respiratoria de origen pulmonar en los neonatos, se realizó un estudio retrospectivo de corte transversal, descriptivo, en un grupo de pacientes con este diagnóstico que ingresaron en la Unidad de Cuidados Especiales Neonatales (UCEN) del Hospital Ginecoosbstétrico Ramón González Coro, en el período del 1ro de enero al 31 de diciembre de 2006. Se registraron 133 neonatos con dificultades respiratorias de origen pulmonar, para una frecuencia de 4,7 por ciento. La mayor parte de los pacientes estudiados nacieron por cesárea (61,7 por ciento) y el factor de riesgo materno más frecuente fue la rotura prematura de membrana (18 por ciento). Los recién nacidos a término (55,6 por ciento) y con sexo masculino (65,4 por ciento) fueron los que mayor morbilidad presentaron. La taquipnea transitoria fue la afección respiratoria que más se diagnosticó, con un total de 92 casos para el 69,2 por ciento y la mayoría de los pacientes evolucionaron favorablemente. La enfermedad de la membrana hialina fue la entidad respiratoria que más complicaciones reportó. El índice de ventilación fue el 18,8 por ciento y la neumonía postnatal fue la complicación que más se observó con 8 casos (6,1 por ciento). La tasa de mortalidad en este grupo fue el 1,7 por cada 1000 nacidos vivos(AU)


Syndrome of Respiratory Difficulty is one of more frequent afections in newborn and behaves as one of the main indicators of morbidity and mortality. To characterize the more frequent causes of pulmonar respiratory difficulty in neonates, we made a retrospective, descriptive and cross-sectional study in a group of patients presenting with this diagnosis admitted in Unit of Neonatal Special Care of Ramn Gonzlez Coro Gynecologic and Obstetrics Hospital from January 1 to December 31 2006. There was 133 neonates with pulmonary respiratory difficulty, for a frequency of 4,7 percent. Most of study patients were born by cesarian section (61,7 percent), and the more frequent mother risk factor was premature rupture of membrane (18 per cent). Term newborns (55,6 percent) and of male sex (65,4 percent) presented the greatest morbidity. Transient tachypnea was the more diagnosed respiratory afection with a total of 92 cases (69,2 percent), and most of patients evolved favourably. Hyaline membrane disease was the entity with more complications. Ventilation rate was of 18,8 percent and postnatal pneumonia was the more observed condition with 8 cases (6,1 percent). Mortality rate in this group was of 1,7 for each 1000 live births(AU)

ABSTRACT

Introducción: La enfermedad de membrana hialina (EMH) por deficiencia de surfactante pulmonar en el neonato prematuro es una causa importante de morbimortalidad. El surfactante pulmonar exógeno ha revolucionado el tratamiento de esta entidad en países desarrollados, aunque este beneficio ha sido menor en países en vías de desarrollo. El surfactante porcino de manufactura cubana es económico, y su uso comparado con otros surfactantes es desconocido. Material y métodos: Se llevó a cabo un estudio prospectivo, controlado, aleatorizado, abierto, en 44 recién nacidos prematuros con EMH. Un grupo recibió surfactante bovino (SB) (Survanta), y el otro surfactante porcino (SP) de fabricación cubana (Surfacen). Se evaluó la respuesta en variables de oxigenación y ventilación, días de oxígeno suplementario, ventilación mecánica, incidencia de complicaciones, tiempo de hospitalización y mortalidad. Resultados: 23 pacientes recibieron el surfactante bovino, y 21 el porcino. Los dos grupos fueron similares clínicamente y en sus patrones de respuesta de oxigenación y ventilación, con una tendencia a mayor incremento inicial en la oxigenación en el grupo tratado con SP. La incidencia de complicaciones fue similar en los dos grupos. Fallecieron 10 pacientes (47.6%) en el grupo SP, y 12 (52.2%) en el grupo SB (p>0.05). Conclusiones: El surfactante porcino tuvo efectos clínicos similares al bovino en las variables de oxigenación y ventilación estudiadas; no hubo diferencia significativa en complicaciones y mortalidad. El surfactante porcino es una alternativa efectiva y de menor costo que el surfactante bovino para el tratamiento de la EMH.


Background: Hyaline membrane disease (HMD) due to lung surfactant deficiency in the preterm newborn is an important cause of neonatal morbidity and mortality. Exogenous lung surfactant has transformed HMD therapy in developed countries, but an equivalent benefit has not been accomplished in developing countries due to a variety of factors. Porcine surfactant developed in Cuba is an inexpensive alternative to other surfactants, and its use has not been studied in our settings. Methods: A randomized, open, prospective and controlled trial was undertaken in 44 preterm newborns with HMD diagnosis. One group received bovine surfactant (BS) (Survanta) and the other Cuban porcine surfactant (PS) (Surfacen). The following clinical response variables were evaluated: oxygenation and ventilation indexes, days with supple mentary oxygen, days with mechanical ventilation, incidence of compli cations, time of hospitalization, and mortality. Results: 23 Patients received bovine surfactant and 21 the porcine type. The two groups were clinically similar, with patterns of oxygenation and ventilation response that were the same between groups, with a tendency to higher initial oxygenation increase in the PS group. The incidence of complications was similar between groups. Ten Patients (47.6%) died in the PS group, versus 12 (52.2%) in the BS group (p>0.05) Conclusions: Porcine surfactant had similar clinical effects than bovine surfactant in the oxygenation and ventilation variables, with no significant differences in complications or mortality. Porcine surfactant is an effective and lower cost alternative to bovine surfactant in the treatment of HMD.

ABSTRACT

OBJECTIVE: Improved survival of low birth weight, premature babies have increased the incidence of retinopathy of prematurity. This hospital-based, prospective, study was undertaken to determine its incidence and risk factors in our neonatal unit. METHODS: Neonates with gestational age < or = 35 weeks and/or birth weight < or = 1500 gm born over a one-year period were examined by indirect ophthalmoscopy between 2 to 4 weeks after birth, and followed up till retinal vascularisation was complete. Maternal and neonatal risk factors were noted and data analyzed by statistical package SPSS-10.0. RESULTS: Sixty babies were thus examined. The incidence of retinopathy was 21.7% in the cohort, 33.3% in babies < or = 32 weeks gestation and 36.4% in babies weighing < or = 1250 gm. Oxygen (p=0.01), sepsis (p=0.04) and apnoea (p=0.02) were independent risk factors. Retinopathy was significantly more severe in babies with hyaline membrane disease (p=0.02) and lower birth weight (p=0.02). Severe disease was never seen before 6.5 weeks of age. CONCLUSION: Indirect ophthalmoscopy should be performed at 4 weeks of post natal age in all preterm babies with birth weight < or = 1500 gm, and intensified in the presence of risk factors like oxygen administration, apnoea and septicemia.

ABSTRACT

OBJETIVO: Obter a incidência de displasia broncopulmonar (DBP); avaliar os fatores maternos e neonatais associados com a doença; determinar a correlaçäo entre DBP e a evoluçäo dos recém-nascidos. MÉTODOS: Os dados foram coletados prospectivamente de 153 recém-nascidos com peso de nascimento inferior a 1.500 g, nascidos em Campinas de setembro de 2000 a abril de 2002 e tratados no Hospital Universitário. Foram utilizados razäo de taxas de incidências com intervalo de confiança de 95 por cento (IC 95 por cento), regressäo Breslow-Cox, teste t de Student, regressäo linear e teste exato de Fisher. RESULTADOS: Entre os 124 recém-nascidos que sobreviveram aos 28 dias de vida, 33 (26,6 por cento) apresentavam DBP. Peso de nascimento < 1.000 g (5,6; IC 95 por cento 3,0; 10,4) e idade gestacional < 30 semanas (4,0; IC 95 por cento 2,1; 7,2) foram correlacionados com um aumento na incidência de DBP. A regressäo de Breslow-Cox mostrou que outros fatores, incluindo sexo, índice de Apgar, doença da membrana hialina (DMH), uso de corticóide pré-natal, doença hipertensiva específica da gravidez (DHEG), tipo de parto e idade materna näo foram associados com DBP. As médias dos dias de internaçäo e de ventilaçäo mecânica nos recém-nascidos com e sem DBP foram, respectivamente, 78,8 dias (DP = 26,67) contra 43,0 dias (DP = 14,49) (p < 0,01) e 27,2 dias (DP = 21,26) contra 3,7 dias (DP = 3,02) (p < 0,01). A média de ganho de peso por dia foi menor nos recém-nascidos com DBP (p < 0,01). A mortalidade para recém-nascidos com DBP foi de 21 por cento (p < 0,00005). CONCLUSÕES: A idade gestacional e o peso de nascimento foram fatores inversamente proporcionais à incidência de DBP. Uma vez desenvolvida a doença, os recém-nascidos necessitam maiores tempos de suporte ventilatório e de internaçäo, apresentando inadequado ganho de peso e maior mortalidade quando comparados aos recém-nascidos sem DBP

ABSTRACT

The incidence, etiology and the outcome of respiratory distress in 243 consecutive liveborn very low birth weight neonates (VLBW) were analysed. One hundred and forty six (60%) VLBW neonates developed respiratory distress. Hyaline membrane disease, congenital pneumonia and transient tachypnea of the newborn were the major underlying causes (35.6%, 28.1%, and 27.4% respectively). The mortality rate was significantly higher in neonates with respiratory distress (72 of 146, 49.3%) than in those without distress (28 of 97, 28.8%) (p < 0.05). This difference was more sharply reflected in the 1000-1249 birth weight group and in the 29-32 weeks gestation group. Respiratory distress is a significant determinant of VLBW mortality.

ABSTRACT

Introducción. La broncodisplasia pulmonar es una complicación frecuente del recién nacido prematuro que desarrolla enfermedad de membrana hialina; su repercusión sobre el neurodesarrollo incluye: alteraciones motoras, retardo en la adquisición de habilidades lingüísticas y microcefalia; recientemente se ha relacionado con el desarrollo de movimientos involuntarios de tipo coreico y temblor de origen extrapiramidal durante el primer año de vida. Caso clínico. Se reporta un caso típico de discinesia con movimientos coreicos, temblor, postura distónica y dificultades en la succión y deglución asociadas a disquinesia oro-buco-lingual que se desarrolló en los primeros 3 meses de vida en un paciente con broncodisplasia pulmonar y dependencia de suplementos de oxígeno inhalado. Conclusión. Se hace hincapié en el diagnóstico diferencial de los trastornos de la succión y deglución, los hallazgos video-electroencefalográficos y la necesidad de reconocer correctamente el síndrome, así como su tratamiento farmacológico

ABSTRACT

The goal was to study the cardiotocographic alterations due to abrupt oligoamnios which follows the premature rupture of membranes. In this way, 96 antepartum cardiotocograms were analysed in 72 pregnant women with premature rupture of membranes, between the gestational ages of 28 weeks and 41 weeks and 6 days, constituing the studied group. The cardiotocograms of the these patients were compared to 72 cardiotocograms of 72 normal pregnant women with integral membranes of gestational ages similar to the pregnant women of the studied group, constituing the control group. The compared cardiotocografic variables were: the basal fetal heart rate, periodic and nonperiodic alterations of basal fetal heart rate, and acelerated response to vibroacustic stimulation. In the studied group were still carried ou the correlation between the cardiotocogram and APGAR score in the first and fifith minute, the perinatal underliving, the gestacional age adequacy and also the membrane ruptures time. They have still evaluated the validity ot the antepartum cardiotocography concerning to the sensibility, specificity, positive and negative predictive values. They conclude that the premature rupture of membranes diminishes the variability of basal fetal heart rate the fetal reactivity to fetal corporal movements and to vibroacustic stimulation, and also predisposes to the apperearence of variable desacelarations,contributes to a greater number of subnormal, pahtological cardiotocograms, associates to lower rates fo APGAR score in the fifth minute, suggests a greater incidence fo small for the gestational age infant and finally associates with a large incidence of pathological cardiotocograms after 7 days of rupture of membranes. The antepartum cardiotocography showed to be propedeutic with a good sensibility and specificity, and also a good negative predictive value, even in patients with premature rupture of membranes. At last, before pregnant women with premature rupture of membranes in which the conservative managements is to be taken , the accomplishment of antepartum cardiotocography in imposed, aiming at the perinatal results improvement

ABSTRACT

Se presentan los resultados de un estudio realizado con el propósito de conocer la morbilidad y mortalidad de 18 recién nacidos (RN) prematuros con enfermedad de membrana hialina (EMH) a los cuales se les aplicó surfactante exógeno (grupo A) comparados con un grupo histórico de 20 niños sin surfactante (grupo B). Al confrontar las diversas variables en estudio no se encontró una diferencia estadística en cuanto a edad de gestación (29.0 ñ 2.5 ñ 3.2 semanas) y peso (1,210 ñ 350 vs 1,120 + 330g); tampoco hubo diferencias en cuanto a la vía de nacimiento, Apgar, sexo y trofismo. En relación a la morbilidad y letalidad, se encontró una mayor frecuencia de niños con persistencia del conducto arterioso en el grupo A (p<0.01) al igual que para neumonía (p<0.01). Hubo mayor letalidad en el grupo B (p<0.01) y mayor incidencia de displasia broncopulmonar. Se concluye que el uso de surfactante exógeno es imperativo para modificar el curso de la EMH en neonatos con deficiencia de surfactante; con su uso disminuye la letalidad y la displasia broncopulmonar

ABSTRACT

El uso del catéter arterial umbilical continúa siendo de amplia utilización en los recién nacidos críticamente enfermos, con riesgo de complicaciones como sangrado, arritmias cardiacas, onfalitis, trombosis, sepsis, enterocolitis, hemorragia intraventricular, etc. Presentamos el caso de un neonato prematuro de 990g con enfermedad de membrana hialina grave que presentó, trombosis arterial aguda que involucró el miembro inferior izquierdo, Se manejó con estreptoquinasa (trombolítico) y finalmente la lesión se limitó con pérdida de la articulación tarso-metatarsiana y del calcáneo. El diagnóstico de trombosis en la actualidad se realiza por ultrasonido-doppler, el manejo puede ser heparina, trombolíticos y/o quirúrgico. Existe escasa experiencia con el uso de trombolíticos en la etapa neonatal

ABSTRACT

Os autores estudaram 162 recem-nascidos prematuros com DMH, internados de marco de 1982 a dezembro de 1987 na Unidade de Terapia Intensiva Neonatal do Hospital Santa Lucia, Brasilia - DF. O diagnostico da DMH foi feito considerando-se o quadro clinico, radiologico e gasometrico. Os recem-nascidoscom DMH eram submetidos a pressao positiva continua de vias aereas (PPCVA) com intubacao orotraqueal, se a PaO2 fosse menor do que 100 mmHg, com o neonato numaFiO2 de 60% sob capacete. Alguns necessitaram tambem de ventilacao com pressao positiva intermitente (VPPI). Dos 126 recem-nascidos, 132 (81,5%) foram submetidos a PPCVA, com ou sem VPPI. Ocorreram 45 (27,8%) obitos, com a letalidade sendo maior nos grupos de menor peso. As complicacoes mais frequentes foram a atelectasia pos-extubacao e o pneumotorax .

ABSTRACT

Com base em nove autópsias, sete de recém-nascidos e duas de lactentes, cujo tempo de sobrevida variou de quatro dias a cinco meses, os autores procedem a uma revisäo dos conceitos fundamentais relativos à displasia broncopulmonar. As necropsias foram completas de acordo com as normas vigentes no Departamento de Patologia e Apoio Clínico da Universidade Federal Fluminense, Hospital Universitßrio Antonio Pedro. Graças a tal procedimento pudemos concluir que a DBP integra uma constelaçäo patológica que compromete o organismo em sua totalidade. E, a propósito, vale lembrar que a descriçäo de Northway ocupava-se apenas das lesöes pulmonares. Os autores analisam o complexo causal da DBP, destacando a prematuridade, a DMH, a oxigenoterapia e o barotrauma, este último responsável por complicaçöes pulmonares da maior gravidade. As lesöes pulmonares säo representadas por atelectasia, enfisema, espessamento septal por fibrose que se instala precocemente, além das que comprometem brônquios e bronquíolos. As lesöes vasculares sugerem a importância da hipertensäo pulmonar em sua gênese. A persistência do canal arterial foi fator de agravamento do quadro mórbido, observado na maioria dos nossos pacientes. As lesöes observadas ao nível de fígado, rins e coraçäo foram analisadas, bem como os fenómenos hemorrágicos de difícil e discutível interpretaçäo.

ABSTRACT

Ten critically-ill preterm infants with severe hyaline membrane disease received tolazoline because of persistent hypoxemia refractory to the administration of 100% oxygen and mechanical ventilation. Seven infants (70%) responded immediately with an increase in PaO2 greater than or equal to 20 mmHg in the umbilical arterial gas within 60 minutes after bolus infusion (1 to 2 mg/kg) of tolazoline. Twenty-four hours later after the tolazoline infusion, the FiO2 had been decreased from 1.0 to a mean of 0.82 +/- 0.16, and the MAP from 16.5 +/- 1.8 to 15.6 +/- 4.5 cm H2O. Four of 7 infants (57%) who had an immediate response survived, whereas none survived out of 3 infants who failed to respond initially. Three infants experienced relatively severe complications possibly related to tolazoline. There appears to be a place for the use of tolazoline in a severely hypoxemic infant with hyaline membrane disease who is being ventilated, and in whom arterial oxygenation cannot be improved by a further increase in the inspired oxygen concentration or by an alteration of ventilator settings.
