Apnea is associated cfeina neurodevelopmental impairment in very low birth weight infants. Introduction Treatment of apnea of prematurity includes pharmacological approach with caffeine, a powerful stimulant of the central nervous system that reduces occurrence of neonatal apnea, promotes consolidation of a regular pattern of breathing and increases alveolar ventilation.

Serum levels of caffeine in umbilical cord and apnea of prematurity. Detected levels of caffeine in umbilical cord blood did not decrease occurrence of apnea of prematurity, but it had a borderline effect delaying its occurrence, suggesting that even a low level of caffeine cateina umbilical cord blood might delay occurrence of apnea spells.

cafeina en apnea del prematuro pdf

In the group with no detected caffeine in umbilical cord blood, gestational age was significantly lower, and they required more respiratory support, suggesting a role for immaturity in this group of patients. Definicion Apnea significa interrupcion de la respiracion. None of them showed significance Table 3.

Before the collection and inclusion, a consent term was read to the parents or person in charge. The sample was composed of preterm neonates with birth weight between 1, and 2, g and gestational age under 37 weeks, born at HCPA between March and May Neonates were divided into detectable and undetectable caffeine in umbilical cord blood.

Diagnosis and management of bacterial infections in the neonate. As caffeine is a substance that crosses the placental barrier, it could have an intrauterine stimulation of the fetus’s respiratory center. Cochrane Database Syst Rev.


In our study, caffeine detection rate and serum levels of caffeine were higher than the results of that study, probably because our population had higher caffeine ingestion. The first choice for treatment of apnea of prematurity in our unit is methylxantine, and its use would bias the result. Como citar este artigo.

Preterm infants with birth cel of to 1, g treated with caffeine during the first 10 days have a reduced rate of bronchopulmonary dysplasia, and present a better neurodevelopmental outcome at 18 to 21 months than a control group.

Discussion This study showed that neonates with detectable and undetectable levels of caffeine in umbilical cord blood had similar occurrence of apnea, and among the neonates who presented apnea, occurrence was later in preterm neonates with detectable levels of caffeine.

For the diagnosis of early sepsis, the study considered patients that presented clinical conditions and positive blood culture. A simple liquid chromatographic method applied to determine caffeine in plasma and tissues.

For the diagnosis of meningitis, those with abnormal cerebrospinal fluid and positive culture were considered. No difference was observed in occurrence of apnea between both groups, but diagnosis of apnea was obtained through pneumography, which was performed only after clinical stability and in patients that did not require ventilatory support or oxygen therapy, thus excluding patients with serious conditions.

In a retrospective study that applied questionnaires on cigarette and caffeine consumption during pfematuro after pregnancy to mothers of infants with apnea before a polysomnography as part of the patient’s assessment determined that maternal caffeine and cigarette use during pregnancy was related to central apnea.

Schreiber-Deturmeny E, Bruguerolle B. Echocardiogram was performed in all preterm neonates with clinical suspicion of PDA. High-pressure liquid chromatography HPLC was the method used to determine caffeine, which has been employed in several studies on caffeine dosage.


Results Umbilical blood was collected in preterm neonates; 21 of them were subsequently excluded seven for presenting apnea once with no need for treatment, five for remaining in mechanical ventilation until the fourth day of life, three for PIVH degrees 3 and 4, one for exchange transfusion, five for methylxantine prior to extubationand three were lost two due to insufficient sampled quantity for caffeine dosage and one due to family request. Determination of caffeine, theophylline and theobromine in serum and saliva using high performance liquid chromatography.

Níveis plasmáticos de cafeína no cordão umbilical e apneia da prematuridade

Transplacentally acquired caffeine and the occurrence of apnea, bradycardia, and periodic breathing in preterm infants: Group 1 was formed by 87 newborns and group 2 by Logistic regression analysis showed that none of those variables was associated with presence of caffeine in umbilical cord blood. Effects of maternal smoking and caffeine habits on infantile apnea: There was no association between occurrence of apnea spells and presence of caffeine in umbilical cord blood. Diagnosis of apnea was performed through patient’s monitoring, and it was defined as interruption of breathing for 20 s or more, or interruption of shorter duration if followed by cyanosis, hypotension or bradyarrhythmia.

It was a;nea that neonates chronically exposed to intrauterine caffeine could be more sensitive to occurrences of hypoxia. Newborns were followed for the first 4 days for occurrence of apnea spells.
