objective: asphyxia  is  a  major  cause  of  acute  mortality  and  chronic  neurologic  disability  in  neonates. we sought to  define  the  predictive  values  of  serum  concentrations  of  interleukin-1β  in  newborns  with perinatal asphyxia to see if there is a relation between interleukin-1β (il-1β) levels to the short term neurological deficit.  methods: this was a prospective (case-co...

Intracellular potentials were recorded from inner hair cells in the guinea pig cochlea. Transient asphyxia was induced by interrupting respiration for brief periods. Asphyxia caused a hyperpolarization of the resting membrane potential (resting Em). The hyperpolarization averaged 2.9 mV for 30 s asphyxias and 5.7 mV for 45 s asphyxias. The membrane potential recovered quickly after normal venti...

background: perinatal asphyxia is a common cause of infant morbidity and mortality and long-term neurological disabilities. due to the high costs of admission, a large proportion of births and neonatal deaths occur in non-hospital settings. this study aimed to evaluate the incidence rate of perinatal asphyxia before and after the implementation of the health improvement program. methods: this d...

This study examined the hypothesis that the development of hydrops fetalis after asphyxia in the 0.6 gestation sheep fetus would be associated with activation of the fetal renin-angiotensin system (RAS). Fetuses were randomly assigned to either sham occlusion (n = 7) or to 30 min of asphyxia induced by complete umbilical cord occlusion for 30 min (n = 8). Asphyxia led to severe bradycardia and ...

About four million newborn children die annually. Almost one quarter (23%) of these deaths are caused by perinatal asphyxia, most of them in developing countries [1-3]. The clinical signs following perinatal asphyxia have been called hypoxic ischemic encephalopathy (HIE). HIE occurs in 1 to 3 per 1,000 live births in high income countries, and up to 20 per 1,000 live births in low and middle-in...

Background: Asphyxia is one the most important causes of neonatal mortality and morbidity. It is suggested that magnesium may have a protective role against cellular damage during hypoxic brain insult, or change effect post-asphyxia consequences. Our study was performed for comparison of serum magnesium in neonates with and without asphyxia. Methods: This study was done in Neonatal Ward of Ali-...

Perinatal asphyxia during delivery produces long-term disability and represents a major problem in neonatal and pediatric care. Numerous neuroprotective approaches have been described to decrease the effects of perinatal asphyxia. Enriched environment is a popular strategy to counteract nervous system injuries. The aim of the present study was to investigate whether enriched environment is able...
