Filter by:Preterm birth and perinatal events related can interrupt microscopic maturation of the developing white matter leading to diffuse injury and subsequent neurocognitive impairments. Brain maturation can be studied using diffusion tensor imaging but is difficult to assess early after birth, repeatedly and at the bedside. Supersonic Shear wave Imaging (SSI) could be of interest in this clinical setting. This technique, already investigated in adults (breast, thyroid or liver fibrosis staging), has not been yet evaluated in neonates. Objective: To describe the feasibility and reproducibility of quantitative elasticity mapping in preterm infants and to correlate to gestational age. Methods: SSI is a quantitative stiffness imaging technique based on the combination of a remote palpation induced into tissues by the radiation force a focused ultrasonic beam and an ultrafast ultrasound imaging sequence. Such ultrafast frame rates permit to track in real time the displacements induced by the propagation of the resulting shear waves. For each pixel, the shear wave speed can be estimated locally and enables quantitative mapping of the local shear elasticity (characterizing the stiffness in kPa). In this study, we will use a new generation of ultrafast ultrasound scanners (Aixplorer®, Supersonic Imagine, Aix en Provence, France) with a linear L10-2 probe (256 elements, 6 MHz) in neonates born between 25 and 40 weeks' gestation (n=100). Three separate acquisitions will be obtained for each area of interest both on right and left sides and stiffness was measured using a unique ROI of 2.5 cm².
- Hypothermia, infections ,and ineffective breastfeeding are some of the commonest causes of deaths among premature and low birth weight LBW infants. Even if the infants are born in facilities, incidences of cold stress are possible due to insufficient resources, space and incompetent practices to manage hypothermia in the immediate postnatal period. Kangaroo Mother Care is a well-known intervention to address the issues related to preterm births, such as hypothermia, infection and prolong hospitalization.Besides significant outcome of KMC interventions for preterm infants, no interventional study has been found in literature in Pakistani context. Looking at the potential benefits of KMC in reducing the related complications of prematurity, the study aims to identify the effectiveness of KMC among preterm and LBW infants born in secondary hospital of Aga khan University hospitals. Hypothesis I Ha: KMC is effective in reducing the incidences of hypothermia among preterm and LBW infants as compared to the usual care. Hypothesis II Ha: There is a difference in breastfeeding behavior and breastfeeding outcome among experimental and control group. Secondary Hypothesis Hypothesis I Ha: There is an association between KMC and frequency of suspected infections during hospitalization. Hypothesis II Ha: There is a difference in length of stay among experimental group and control group. Hypothesis III Ha: There is a relationship between KMC and weight gain of infants till four weeks. Hypothesis IV Ha: There is difference in rate of hypothermia among experimental group and control after discharge from hospital.
The purpose of this study is to examine the influence of premedication drugs Atropin, Fentanyl and Mivacurium and of endotracheal intubation on cerebral oxygenation and cardiac output in term and preterm newborn infants. Two different protocols of premedication are compared.
