Background: Preterm infants with Intra-Ventricular Hemorrhage (IVH) are at risk for developing significant complications, including post hemorrhagic hydrocephalus and seizures. Neonatal seizures are the most common overt manifestation of neurological dysfunction in the newborn, and is associated with short- and long-term adverse effects.
Objective: The aim of the study is to evaluate the value of Peripheral Neutrophil- lymphocyte ratio (NLR) as a predictor of seizure in preterm infants with intra-ventricular hemorrhage.
Methods: This prospective cohort study that comprised 60 Preterm infants with IVH admitted at NICU pediatric department Tanta university hospital from November 2019 to May 2020, Preterm infants were divided into two groups according to incidence of seizure.
Preterm infants in this study subjected to Careful history taking, clinical examination and investigations (laboratory and Trans-cranial ultrasound) as well as analysis of result and follow up clinical status for development of seizure.
Results: There was a statistically highly significant difference regarding NLR and development of seizure with p value <0.001 (NLR ≥ 2.3 with sensitivity 96%, specificity 93%, Area under the curve 0.849 and accuracy 84.9%).
Conclusion: NLR is a predictor of seizure in preterm infants with intra-ventricular hemorrhage.
To determine the efficacy of papaverine in improving myocardial protection by causing a uniform distribution of the cardioplegic solution, a prospective study was carried out in 200 consecutive patients undergoing various open heart procedures. Several parameters (creatine kinase MB, electron microscopy of myocardium, perioperative myocardial infarction rate, frequency of postoperative arrhythmias) were monitored and compared with those of a control group which consisted of the previous 200 consecutive patients in whom the same cardioplegic solution was used, but without papaverine. In the papaverine group the operative mortality due to low cardiac output was 0.5% compared to 3%, and the spontaneous recovery of the heart after release of the aortic cross-clamp was 89% compared to 47% in the control group (P less than 0.01). The perioperative myocardial infarction rate was 5% and the incidence of postoperative temporary arrhythmias was also 5% in the papaverine group, while in the control group the perioperative myocardial infarction rate was 10% and the postoperative arrhythmia incidence was 13% (P less than 0.01).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
