  1. 1. Birth asphyxia Fetal scalp blood sampling and risk factors for hypoxic ischemic encephalopathy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lena Liljeström; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asphyxia; fetal scalp blood sampling; hypoxic ischemic encephalopathy; obstetric emergencies; operative deliveries for fetal distress; overweight; short stature; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Preventing birth asphyxia is a major challenge in delivery care. The aims of this thesis were to evaluate fetal scalp blood sampling (FBS) and explore risk factors for moderate to severe neonatal hypoxic ischemic encephalopathy (HIE). READ MORE

  2. 2. Pathophysiology of intrauterine asphyxia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna-Karin Welin; Göteborgs universitet.; Gothenburg University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asphyxia; ECG; endotoxemia; fetal sheep; inflammation; melatonin; periventricular leukomalacia; preterm;

    Abstract : Background: The premature infant is at increased risk of cerebral white matter damage, oftenreferred to as periventricular leucomalacia, PVL, which is associated with later developmentof cerebral palsy and cognitive impairment. The etiology of PVL remains unclear, but ischemia-reperfusion followed by generation of free radicals and intrauterine infections havebeen suggested to play an important role. READ MORE

  3. 3. Perinatal brain injury - markers and mediators. Non-protein-bound iron and pro-inflammatory cytokines in newborn infants and neonatal pigs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Sävman; Göteborgs universitet.; Gothenburg University.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asphyxia; hypoxia; posthemorrhagic ventricular dilatation; preterm; newborn; perinatal; brain; cerebrospinal fluid; cytokines; IL-1ß; IL-6; IL-8; TNF-a; non-protein-bound-iron;

    Abstract : Two groups of newborn infants have an increased risk for perinatal brain injury; preterm infants and term infants subjected to birth asphyxia. Experimental studies indicate that hypoxic-ischemic insults in the perinatal period initiate a secondary neurotoxic cascade including formation of toxic reactive oxygen species as well as an inflammatory response with elevated levels of potentially neurotoxic cytokines.

  4. 4. Inflammation and ischemia in the developing brain - modifying effects of hyperoxia and adrenoceptor activation

    University dissertation from Department of Pediatrics, Lund University

    Author : Tina Markus; Lunds universitet.; Lund University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenergic; preconditioning; excitotoxicity; tissue culture; hyperoxia; resuscitation; asphyxia; sensitization; TNF-alpha; inflammatory mediators; hippocampus; neonate;

    Abstract : Inflammation and ischemia are common causes of perinatal brain damage. Ventilation with pure oxygen has previously been the prime choice during resuscitation following fetal asphyxia. READ MORE

  5. 5. Fetal reactivity assessment during intrapartum stress by analysis of the fetal ECG signal

    University dissertation from Department of Pediatrics, Lund University

    Author : Sofia Blad; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FHR variability; fetal ECG; Asphyxia; Intrauterine infection; Residual method; STAN;

    Abstract : Fetal responses to the stress of labour and delivery are constituted by a combination of changes in neuronal, hormonal and organ based reactions. The aim of electronic fetal monitoring is to identify fetuses at risk of hypoxia during birth, thus enabling timely intervention to avoid an adverse outcome. READ MORE
