Filter by:The aim of this study is to investigate the effect of baby massage applied to babies with retinopathy of prematurity on the pain and comfort of the newborn. This was randomised-controlled study in the NICU at the Health Sciences University Bursa High Specialization Training and Research Hospital, Bursa, Turkey. The population of the study will consist of preterms hospitalized in the neonatal intensive care unit during the time period of the study. In the calculation of the sample size, the power level was 80% and the significance level was 5%. When the effect size was determined as 0.8 in the examination of the difference between the experimental and control groups in terms of the premature infant pain profile (PIPP) variable, it was determined by the statistical expert that the number of babies to be included in each group was 26 and 52 babies in total should be included in the study. Based on this, the study sample was determined as 60 preterm infants in 30 experimental and 30 control groups. Block randomization method will be applied in the randomization of the groups. Case report form, PIPP=Premature Infant Pain Scale and Premature Infant Comfort Scale (PBIQ) will be used to collect the study data. Patients included in the study will be examined by the same ophthalmologist. The infant massage to be applied before the examination will be applied by a single nurse=researcher. Video recordings will be taken before and during the ROP examination and evaluations will be made by two neonatal nurses other than the researcher. Infants will be massaged by the researcher in accordance with IAIM guidelines and massage techniques. Total massage time will be equal for each infant. The researcher has an IAIM infant massage certificate. Before starting the infant massage, jewelry will be removed and hands will be washed. In the study, leg and face massage will be applied among the massage techniques in the IAIM guidelines.
Background: Preterm infants undergo serial eye examinations during their hospital stay to monitor for the development of a specific disease termed "retinopathy of prematurity". While those examinations are known to cause significant pain and stress, the current standard of care (sucrose and local anesthesia) is not adequate in terms of alleviation of pain. Purpose: The goal of this clinical trial is to test the effectiveness of dexmedetomidine for pain management in preterm infants undergoing routine eye examinations. The main questions it aims to answer are: - Does dexmedetomidine reduce the pain scores of preterm infants during and shortly after eye assessments in comparison to placebo (saline 0.9%). - Does dexmedetomidine cause more adverse effects than placebo. In this crossover study participants will receive either dexmedetomidine or saline 0.9% intranasally 30 minutes before the examination, on top of the current standard of care. The participants will be monitored closely for 5 hours to note differences in adverse effects. The researchers will use video monitoring to assess the pain scores using a standardized and validated scoring system.
Retinopathy of prematurity (ROP) is a widely known retinal vascular disorder in preterm infants and a leading cause of visual disability or blindness in children. Advances in antenatal care have resulted in an increase in the survival rate of infants with extremely low birth weight (BW). Approximately 90% of infants who develop ROP do so by a postmenstrual age of 46.3 weeks. In certain patients with or without treatment, the retina may fail to fully vascularize or may develop vascular abnormalities, thus demonstrating persistent avascular retina (PAR) or anomalous vessel findings at the periphery. Because of the advent of technologies such as ultrawide-field fluorescein angiography (UWFFA) persistent vascular abnormalities can be detected more readily and investigated.
The goal of this retrospective observational study is to [learn about the correlation between hyperbilirubinemia and retinopathy of prematurity in preterm infants. The main question it aims to answer are: • To evaluate the possible effect of neonatal jaundice linked to the presumed protective antioxidant action of bilirubin on the development of ROP, compared to a control group which, although presenting ROP, did not develop jaundice.
The main goal of this trial is to test if: automated adjustment of supplemental oxygen to preterm infants in noninvasive respiratory support based on feedback from a measurement of blood-oxygen saturation results in more stable blood-oxygenation compared to routine nurse controlled adjustment of oxygen
Retinopathy of prematurity is a leading cause of childhood blindness worldwide. The fovea, a critical location in the retina determining visual acuity and visual function, and the blood vessels around it, are abnormally developed in infants with retinopathy of prematurity. However, how these blood vessels form during development of the human fovea remains unclear. This research will advance our understanding of the fundamental knowledge of how the blood vessels around the fovea form in infants, and how they change in diseased states such as preterm birth or retinopathy of prematurity.
Cord blood will be taken after birth for evaluation of cytokines level. At age of 4-6 weeks, we will do fundus examination for babies . Retrograde, we will study the perinatal risk factors in subjects found to have retinopathy. Follow up fundus will be done according to results of the first examination. By this study,we will be able later on to predict whom of preterm infants are more prone to develop retinopathy of prematurity.
Premature birth is a major cause of neonatal death in addition to neonatal asphyxia and infections. Early in life, premature babies must get aggressive nutrition so that there is no extrauterine growth restriction (EUGR) in the Intrauterine Growth Restriction (IUGR) group compared to the non-IUGR group. Other factors that also play a role are long episodes of fasting, the fulfillment of nutrition (macro and micronutrients) from the start, time to start breastfeeding (ASI), duration of parenteral total administration, the incidence of respiratory distress syndrome and incidence of necrotizing enterocolitis. Zinc is one of the micronutrients which is very risky for deficiency in premature babies. Babies with zinc deficiency experience growth disorders as much as 67%. In India, infants who received zinc supplementation increased after being given 10 days of zinc supplementation and lower mortality rates in the group with supplementation. Very low birth weight babies and bronchopulmonary dysplasia who received zinc supplementation during the week showed good clinical progress and the growth rate also increased. The investigators believe this study has the potential for decreasing infant mortality from its current level and can be a growth indicator for preterm babies.
The purpose of this study is to evaluate the safety and efficacy of oral/local propranolol in preterm newborns who diagnosed as early phase of retinopathy of prematurity (ROP).
Periventricular leukomalacia (PVL) is one of the most common brain injuries that occur in preterm infants. Inflammation, hypoxia-ischemia, free oxygen radical formation and excitotoxicity are all known pathogenic mechanisms that mediate this injury. Erythropoietin (EPO) has been shown to be protective against hypoxic-ischemic and inflammatory injuries. During the past decade, recombinant human Epo (rhEpo) has been widely used in preterm infants to prevent or treat the anemia of prematurity, in general, rhEpo has been considered to be safe and well tolerated in preterm infants. EPO was considered not capable of passing through blood-brain-barrier at low dose. Evidence from animal experiments reveals that rhEpo must be given in high doses at the beginning or within a short (up to 6 hours), critical time period after the onset of brain injury to achieve a significant neuroprotective effect. A recent study using high-dose rhEpo (3000 U rhEpo/kg body weight at birth) for neuroprotection in very preterm infants revealed that no signs of adverse effects of early high-dose rhEpo treatment in very preterm infants were identified. Contrary to this, a recent study in PVL of a rat model revealed that using a low dose rhEpo (50-100 U/kg) was effective in the treatment of brain damage induced by hypoxia-ischemia and did not affect normal oligodendrocyte maturity. On this basis, the researchers intent to investigate (1) whether low-dose rhEpo (100 U/kg) or high-dose rhEpo (3,000 U/kg) given to very preterm infants (gestation age < 32 weeks) immediately after birth and subsequently during the first 2 days is safe and possesses neuroprotective properties;(2) whether there are gender differences in response to the hypoxia-ischemic insult and EPO treatment; (3)the pharmacokinetics of low dose and high dose rhEPO. Very preterm infants with gestational age of < 32 weeks and admitted to the NICU are eligible for enrollment.
