Related to meconium aspiration: meconium staining


inhalation of some foreign material; aspiration of vomitus, blood, or mucus may occur when a person is unconscious or under the effects of a general anesthetic, and can be avoided by keeping the head turned to the side and removing all such foreign material from the air passages.
A, Types of aspiration. A, Aspiration before swallow caused by reduced tongue control. B, Aspiration before swallow caused by absent swallow response. C, Aspiration during swallow caused by reduced laryngeal closure. D Aspiration after swallow caused by pooled material in pyriform sinuses overflowing into airway. From Logemann J: Evaluation and Treatment of Swallowing Disorders, San Diego, College-Hill Press, 1983.
withdrawal of fluid by an aspirator; the method is widely used in hospitals, especially during surgery, to drain the area of the body being operated on and keep it clear of excess blood and other fluids to facilitate visualization of the surgical field. Sometimes after extensive surgery, suction drainage under the skin is used to speed the healing process.
meconium aspiration inhalation of meconium by the fetus or newborn, which may result in atelectasis, emphysema, pneumothorax, or pneumonia.
risk for aspiration a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as a state in which an individual is at risk for entry of gastric secretions, oropharyngeal secretions, solids, or fluids into the tracheobronchial passage.
vacuum aspiration a form of induced abortion in which the uterine contents are removed by application of a vacuum through a hollow curet or a cannula introduced into the uterus.

* To find out the rate of Meconium aspiration syndrome (MAS) in babies born with Meconium-stained amniotic fluid (MSAF) in GGH, Guntur.
Various demographic characteristics (e.g., name), the mother's medical history (e.g., maternal diabetes, pulmonary disease, idiopathic hypertension), pregnancy conditions (e.g., pregnancy induced hypertension and use of drugs etc.), fetal distress, mode of delivery, need of resuscitation, clinical evidence of hypoxsic ischemic encephalopathy supported by birth history, neonatal lung diseases (e.g., meconium aspiration syndrome, respiratory distress syndrome, etc.), were recorded for all the babies (Table-I).
Mean and Standard Deviation calculated for age; while frequency was calculated for mode of delivery (vaginal, caesarian section) and early neonatal complications (no complications, meconiumst- ained liquor, meconium aspiration and neonatal death).
The risk of meconium aspiration rose steadily up until 2007, when it dropped sharply.
Meconium stained amniotic fluid (MSAF) is associated with higher rate of caesarian delivery, increased need for neonatal resuscitation and meconium aspiration syndrome.2 Higher maternal age, prolonged or premature labour, post-term pregnancy, cholestasis of pregnancy, low-birth weight babies, growth retardation and hypertensive disorders of pregnancy are the major risk factors for the passage of meconium.3 Aspiration of meconium by the foetus remains a relatively common cause of perinatal morbidity and mortality because it is difficult to prevent.4
Meconium aspiration syndrome (MAS) is not prevented by intrapartum ONPS and post-natal endotracheal suctioning of vigorous meconium stained infants.
No differences in outcome were observed between the two groups--including no difference in the incidence of meconium aspiration syndrome; need for mechanical ventilation or duration of mechanical ventilation; oxygen dependency; and length of stay.
"We hardly ever see meconium aspiration syndrome in our institution anymore," said Dr.
Cause of death was meconium aspiration syndrome and septicaemia.
It complicates 10% of all deliveries and is associated with increased perinatal and neonatal morbidity and mortality, including stillbirth, birth injury, meconium aspiration syndrome, neonatal encephalopathy and infant mortality.
[6] Those who had meconium aspiration or were subsequently proven to have neonatal sepsis were included.
Results: Teenage mothers were more likely to suffer from severe anaemia (8% versus 4.3%; p = 0.03) and chorioamnionitis (2.8% vs 0.8%, p = 0.01) and their infants were more likely to suffer from post maturity (4.6% vs 1.8%, P = 0.02) and meconium aspiration syndrome (6.5% vs 2.4%, p less than 0.01) compared to non-teenage mothers.
