A ventilator system provides a respiratory support to critically-ill patients. Its touch screen-based onscreen User Interface (UI) helps medical users in treatment of the patient. The usability problems in medical UIs may contribute to medical errors, affecting the patient condition. Thus, the usability evaluation of medical UIs is extremely important for patient safety. The study of usability evaluation models has revealed that there is a need of domain-specific evaluation model for medical UIs, focusing on medical context; especially critical aspects in Intensive Care Unit (ICU). The proposed UI Component Model is based on UI components, Norman’s action model and identified usability problems. © Springer India 2015.

Background: Cardiac blood flow measurements are useful in the haemodynamic management of neonates. Cardiac blood flows can be estimated with functional echocardiography as follows; flow in Superior Vena Cava (SVC), Right Ventricular Outflow (RVO) and Left Ventricular Outflow (LVO). Studies in preterm infants have shown that abnormal superior vena cava flow is associated with poor neurodevelopmental outcomes. To date, normative data on LVO, RVO and SVC flows has been established for term appropriate for gestational age neonates and preterm neonates, but no data is available on RVO, LVO and SVC flows for term small for gestational age neonates. Objective: To determine Right Ventricular Output (RVO), Left Ventricular Output (LVO) and Superior Vena Cava (SVC) flow after the transitional period in stable full term Small for Gestational Age (SGA) neonates. Design: Observational study. Setting: A tertiary care, perinatal centre in western Maharashtra, India. Participants: Full term (37 to 41 weeks) small for gestational age (weight below 10th percentile for gestational age) infants who were born during the study period. Methods: RVO, LVO and SVC flows were measured by functional echocardiography on day 7 of life in stable full term SGA neonates from January 2011 to August 2011. Infants who required respiratory or cardiovascular support and intensive care unit admissions for any indication and those with a clinical suspicion of an infection within 48 hours after data collection were excluded from the study. Statistical Analyses: Unpaired t-test was used to compare SVC flow between symmetric and asymmetric SGA neonates. Main Outcome Measure: Measurements of RVO, LVO and SVC in term SGA neonates on day 7 of life. Results: We performed measurements in 52 term SGA neonates with a median (range) birth weight of 2.190 (1.600-2.410) kg. Fifty two measurements were analyzed on day 7. The mean (SD) RVO, LVO and SVC flows were 255.59 (57.42), 214.61 (52.04) and 126.28 (31.23) mL/kg/min. Conclusion: This study provides RVO, LVO and SVC flow values in a cohort of stable term SGA neonates after the transitional period.

Introduction: Functional echocardiography, as opposed to echocardiography as performed by the cardiologist, is the bedside utilization of cardiac ultrasound to take after functional and haemodynamic changes longitudinally. Information reflecting cardiovascular capacity and systemic and pulmonary blood flow in sick preterm and term neonates can be observed utilizing this strategy. Information is lacking on its use in neonatal units in India. Aim: To characterize the impact of Functional neonatal echocardiography (FnECHO) programme on decision making in a tertiary care centre in India by evaluating its frequency of use, patient characteristics, and indications. Materials and Methods: Prospective observational study of neonates in a tertiary Neonatal Intensive Care Unit (NICU) in Pune (India) from February 2014 to January 2015. All the neonates undergoing FnECHO during this 12 month period based on clinical findings were included in the study. Data extracted from the review of the clinical notes included gestational age, birth-weight, mode of delivery, Apgar scores, details of respiratory and cardiovascular support, timing of FnECHO and any other clinical diagnosis. The findings of echocardiography were recorded and correlated with the clinical and other laboratory or X-ray findings. If these findings indicated a change in management, it was instituted. Results: A total of 348 echocardiographic studies were performed in 187 neonates (mean 1.86; SD 2.02). The most frequent indication was Patent Ductus Arteriosus (PDA) assessment (n= 174, 50%), followed by haemodynamic instability (n=43, 12.36%). The results of FnECHO modified treatment in 148 cases (42.50%) in the form of addition and/or change in the treatment or avoidance of unnecessary intervention. Conclusion: FnECHO is frequently used in the NICU setting and may be a useful tool to guide treatment. PDA assessment and haemodynamic instability are the most frequent indications. To validate its usefulness, well co-ordinated large prospective studies are needed. © 2015, Journal of Clinical and Diagnostic Research. All rights reserved.

We report a case of an extremely low birth weight (ELBW) infant presenting with pulmonary hemorrhage (PH) in which we have given surfactant after an acute episode of bleeding with severe intractable hypoxemia. Surfactant replacement therapy showed improvement in Mean Airway Pressure (MAP) and oxygenation indices. Our case suggests that surfactant replacement therapy is useful in PH. © 2015, Journal of Clinical and Diagnostic Research. All Rights Reserved.
