Meconium Aspiration
ثبت نشده
چکیده
The decrease in the incidence of MAS in the period of a decade has been attributed to the reduction in post-term delivery, aggressive management of abnormal heart rate monitoring, and decreased number of infants with a low Apgar score. [4]Elective induction of labour for pregnancies at or beyond 41 weeks has been shown to be associated with significant reduction in the incidence of MAS and fewer perinatal deaths compared to expectant management.

Meconium aspiration syndrome in neonates
Perhaps the most significant changes in airway management over the recent years have been in the management of an infant delivered through meconium- stained amniotic fluid( MSAF). MSAF occurs in approximately 10℅ to 20℅ of all deliveries and increases to over 30℅ in deliveries after 42 weeks gestation. Meconium aspiration syndrome ( MAS) occurs in about 2℅ to 5℅ of these cases with a high morta...
متن کاملMeconium aspiration syndrome.
We agree that the passage of meconium in utero is not always due to intrauterine asphyxia and it may be a purely physiological event due to increasing maturity of the fetus. However, a bacterial endotoxin has been recently implicated in "causing the preterm labor and passage of meconium in utero(3). It is to be emphasized that only those neonates who have respiratory\distress with radiological ...
متن کاملFetal Hypoxia and Meconium in Preterm Deliveries and Stillbirth
Purpose: This study was undertaken to assess the relationship between the degree of meconium staining of the extraplacental membranes at birth, meconium aspiration, and pulmonary changes in neonates and stillbirth. Methods: The lungs, extraplacental membranes and placenta from 20 stillborn with meconium-stained membranes and 13 lungs of perinatal deaths were collected and microscopically examin...
متن کاملHemodynamic effects of periodic G(z) acceleration in meconium aspiration in pigs.
The hemodynamic effects of periodic acceleration (pG(z)), induced in the spinal axis with noninvasive motion ventilation (NIMV), were studied in a piglet model of pulmonary hypertension associated with meconium aspiration. Animals (n = 12) were anesthetized, paralyzed, intubated, and supported by conventional mechanical ventilation (CMV). Thirty minutes after tracheal instillation of meconium s...
متن کاملIndigenously designed meconium aspirator.
Meconium stained amniotic fluid (MSAF) complicates delivery in approximately 8% to 25% of live births. Approximately 5% of neonates born through MSAF develop meconium aspiration syndrome (MAS), and approximately 50% of these infants require mechanical ventilation. Meconium aspiration before or during birth can obstruct airways, interfere with gas exchange and cause severe respiratory distress [...
متن کاملCoproporphyrin in urine of newborns with meconium aspiration syndrome.
We evaluated coproporphyrin in the first urine passed by newborn infants with and without meconium aspiration, by spectrophotometric analysis and thin-layer and "high-performance" liquid chromatography. Urines of newborn infants without meconium aspiration contained only very small quantities of coproporphyrin, detected, after partial purification, by "high-performance" liquid chromatography. U...
