Filter by:Anesthesia management of preterm infants is challenging for the anesthesiologist. Because of rudimentary build, many medical and physical problems have shown in treatment of disease such as complications, airway problems, temperature disregulation and deficient drug metabolism. This retrospective study evaluates the perioperative management and postoperative course in premature infants undergoing diode laser photocoagulation (DLP) for retinopathy of prematurity (ROP).
Retinopathy of prematurity (ROP) is a disorder of development of the neural retina and its vasculature that may impact vision in vulnerable preterm neonates for a lifetime. This study utilizes new technology to determine visual and neurological development of very preterm infants in the intensive care nursery, during a period of rapid growth of the retina, optic nerve and brain. The long-term goal of this study is to help improve preterm infant health care via objective bedside imaging and analysis that characterizes early critical indicators of poor vision, neurological development and ROP, which will rapidly translate to better early intervention and improved future vision care.
The development of the retinal vascular network is generally complete during the 3rd trimester of pregnancy but may continue during the first 15 days of life. This late maturation may cause problems in pre-term births and may result in immature vascularization of the retina, a condition called retinopathy of prematurity. Among the different factors affecting the development of the retinal vasculature, the tissue level of omega-3 polyunsaturated fatty acids (PUFA) appears to be a crucial element, as does the form of the PUFA present in the tissues (nature of the phospholipids in their membranes). This project aims to show a possible association between levels of omega-3 PUFA and the onset of retinopathy of prematurity (ROP).
The study includes preterm infants who are being screened for ROP between April 1,2016 and April 30, 2017 in 69 neonatal intensive care units (NICUs) in Turkey. Infants with birth weight (BW) of ≤1500 g or ≤32 weeks' gestation and those with a BW of greater than 1500 g or gestational age (GA) >32 weeks with an unstable clinical course are included. The incidence of any ROP, severe ROP and treatment modalities will be determined. The risk factors for ROP development will also be evaluated.
Retinopathy of prematurity (ROP) is a feared complication of premature birth. If discovered in time, the disease can be treated, and impaired vision or blindness can be reduced. Premature infants are therefore examined regularly after birth. However, the examination is painful and stressful for the infant. Painful experiences might lead to a pathological stress response later in life and should therefore be prevented. In this study skin-to-skin contact with a parent is tested for relief of pain and stress in preterm infants being examined for retinopathy of prematurity.
Most fatty acids, important for development and especially the Omega-3 fatty acids for the brain development are transferred in the third trimester with means that in the premature infant this transport via the placenta is interrupted and the infant is dependent on the concentrations in breast milk which vary depending on the mother's diet and her stores. It has even been suggested that low Omega-3 would be a cause of premature delivery. Many countries have much higher levels of Omega-3 fatty acids in breast milk than found in Sweden and breast milk substitutions are generally now supplemented with the Long Chained Poly Unsaturated Fatty Acids (LCPUFA). Therefore the supplementation to be given can not be seen to give any risks for the infant. On the contrary, several studies have shown that mother who eat equal to or less than twice fish a week during pregnancy give birth to infants with impaired development. Low Omega-3 levels in premature infants between gestational ages of 23 and 40 weeks can be one reason for Retinopathy of Prematurity (ROP) development. Restoration of Omega-3, Dokosahexaenacid (DHA) and Eikosapentaenacid (EPA) to normal in utero levels may prevent ROP by allowing normal vessel growth and survival. An increase of Omega-3 levels bringing levels to within physiological range may prevent development of ROP.
The purpose of this study is to evaluate whether docosahexaenoic acid given by enteral feeding prevent retinopathy of prematurity and/or diminish its severity in preterm infants.
The purpose of this study was to evaluate the long term efficacy and safety of intravitreal ranibizumab compared with laser ablation therapy in patients who were treated for retinopathy of prematurity (ROP) in the core study CRFB002H2301 (NCT02375971)
The aim of the present study is to evaluate the safety and efficacy of propranolol 0.2% eye drops in treating preterm newborns with a precocious stage of retinopathy of prematurity (ROP). Preterm newborns (gestational age 23-32 weeks) with a stage 1 ROP will receive propranolol 0.2% eye drops treatment until retinal vascularization will be completed, but no more than 90 days. Propranolol concentrations will be measured on dried blood spots at the steady state (10th day). Cardiovascular and respiratory parameters will be continuously monitored. Blood samplings checking metabolic, renal and liver functions will be performed periodically, as well as cardiac function, in order to verify the treatment safety. Serial ophthalmological evaluations will be planned to monitor the efficacy of the treatment, the ROP progression and the possible complications.
Retinopathy of prematurity (ROP) is a blinding disease affecting infants born prematurely. These infants do not have enough essential fatty acids to structurally support the retina, the nerve tissue in the eye which allows us to see. A recent study showed that giving omega-3 (n-3) fatty acids to these infants soon after birth made them less likely to need invasive treatments for eye disease. This research trial will give young infants born prematurely n-3 fish oil treatment and look at how this changes factors in the blood that promote disease. Detailed blood studies comparing infants with and without ROP will be performed and the infants will be followed over time to assess their eye development.
