Surfactant Positive Airway Pressure and Pulse Oximetry Trial

InfantNewborn7 more

This study compared the use of continuous positive airway pressure initiated at birth with the early administration of surfactant administered through a tube in the windpipe within 1 hour of birth for premature infants born at 24 to 27 weeks gestation. In addition, these infants within 2 hours of birth, had a special pulse oximeter placed to continuously monitor their oxygen saturation in two different target ranges (85-89% or 91-95%). This study helped determine whether or not these two management strategies affect chronic lung disease and survival of premature infants.

Infant-parent Skin-to-skin Contact During Screening for Retinopathy

Retinopathy of Prematurity

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.

Anesthesia for Retinopathy of Prematurity

Retinopathy

Premature infants experience more respiratory problems after surgical procedures. The investigators aimed to compare general anesthesia with sedation on the need for post-operative mechanical ventilation in infants undergoing retinopathy of prematurity surgery.

Effect of Vitamin E for Prevention of Retinopathy of Prematurity: A Randomized Clinical Trial.

Retinopathy of Prematurity

The retinopathy of prematurity (ROP) is a public health problem, the main causes of ROP are prematurity, use of oxygen, malnutrition and oxidative stress. Vitamin E was used beforehand however its use was stopped because of its association with sepsis and enterocolitis caused by the excipient of vitamin E. The purpose of this study is to use vitamin E to prevent ROP, without the previously used excipients.

Multi-Center Study to Determine the Role of Fatty Acids in Serum in Preventing Retinopathy of Prematurity...

Ophthalmological Disorder

The study is a Randomized Intervention, Multi-Center Study to Determine the Role of Fatty Acids in Serum and Breast Milk in preventing Retinopathy of Prematurity Subjects who meet all inclusion and none of the exclusion criteria will be enrolled into the study. Upon entry into the study, subjects will be randomized and given a unique subject number. A randomized intervention study of 105+105 (number based on power analysis regarding up to date ROP frequency, see 5.1 and 11.1) infants without major malformations born with a gestational age less than 28 weeks + 0 days will be performed.

Skin and Serum Carotenoids in Preterm Infants Fed on a Formula Supplemented With Carotenoids

Retinopathy of Prematurity

The primary objectives of this study are to compare the serum and skin concentrations of beta-carotene, lutein, and lycopene in preterm infants fed preterm formulas with mixed carotenoids to serum concentrations in preterm infants fed preterm formulas with no added carotenoids and to human milk fed infants. The secondary objective of this study is to evaluate the effects of dietary carotenoids on the developing eye. Stages and zones of retinopathy of prematurity (ROP), retinal function, and retinal characteristics will also be examined.

Study on Effective Mydriasis in Premature Infants

Retinopathy of Prematurity (ROP)

The purpose of this study is to compare the dilating effect of 0, 1, 2 or 3 drops of mydriatic (pupil dilating) in premature infants undergoing routine retinal (eye) screening exams for Retinopathy of Prematurity (ROP).

Efficacy and Safety of Mydriatic Microdrops Compared With Standard Drops for Retinopathy of Prematurity...

Retinopathy of Prematurity

The purpose is to assess whether the use of microdrop instillation of phenylephrine 1.67% and tropicamide 0.33% maintains mydriatic efficacy while presents an improved safety profile compared with standard drops of phenylephrine 1.67% and tropicamide 0.33%, which is routine care for pupil dilation during retinopathy of prematurity (ROP) screening in our neonatal intensive care unit.

Changes in Vital Signs and Pupil Diameter Related to Pharmacologic Mydriasis in Premature Infants:...

Retinopathy of Prematurity

Retinopathy of prematurity (ROP) is one of the common anatomic causes of blindness among Filipinos, accounting for 47.7% of the cases. With this retinopathy being preventable and treatable, ROP screening has been proven to be effective in preventing blindness, which is achieved with the usage of mydriatics. Even if the regimen of multiple alternate instillations of 0.5% tropicamide and 2.5% phenylephrine is the one recommended by international guidelines for ROP screening, the mydriatic regimen used by many of the country's institutions is the single instillation of 0.5% tropicamide + 0.5% phenylephrine applied via a cotton wick placed in the inferior fornix (SIW). There have been no studies yet on the safety and efficacy in premature infants of this mydriatic preparation and method, although it is hypothesized that the usage of a cotton wick promotes the possible systemic effects of the mydriatic combination used. This study then aims to determine the safety and efficacy of different mydriatic regimens in premature infants referred for screening of ROP using (1) multiple alternate instillations of 0.5% cyclopentolate hydrochloride and 2.5% phenylephrine (MAI), (2) single instillation of 0.5% tropicamide + 0.5% phenylephrine (SI), and (3) single instillation of 0.5% tropicamide + 0.5% phenylephrine with a cotton wick placed in the inferior fornix (SIW) in a tertiary Philippine hospital. This study was designed as a randomized, double blind, clinical study which enrolled sixty preterm infants referred for ROP Screening from January to July 2011. With instillations via MAI, SI, and SIW, systolic blood pressure (SBP), diastolic pressure (DBP), mean arterial pressure (MAP), heart rate, and oxygen saturation were monitored from ten minutes prior to instillation up to forty-five minutes after instillation. Pupil dilations were also measured at the forty-fifth minute.

Pan-VEGF Blockade for the Treatment of Retinopathy of Prematurity (BLOCK-ROP)

Retinopathy of Prematurity

The purpose of this study is to determine whether a single intravitreal (into the gel of the eye) injection of Avastin 0.625mg or 0.75mg is equivalent (non-inferior) to treatment with standard of care laser in infants with Type I pre-threshold retinopathy of prematurity (ROP) diagnosed at 30-36 weeks gestational age.
