Filter by:Respiratory diseases are associated with high morbidity and mortality worldwide. Proper diagnosis and risk assessment of these conditions are essential for optimal management. Clinicians use three particularly useful tools to identify these conditions when assessing the patient's status: the stethoscope, the pulse oximeter, and the thermometer. The Pneumoscope is an all-in-one device including a digital stethoscope, a pulse oximeter, and a thermometer. This study aims to assess the performance and safety of the Pneumoscope in recording respiratory sounds, body temperature, non-invasive blood oxygen saturation levels and heart rate in children and adults.
The goal of this study is to evaluate the effects of steroids on the early postoperative inflammatory response in patients undergoing elective pediatric congenital cardiac surgery, requiring cardiopulmonary bypass (CPB).
Infants born with heart problems are at risk of developing gut disease due to reduced blood flow to the intestines which can result in poor weight gain, surgery and even death. At present, doctors are often unaware of any gut problems until clinical symptoms present (poor feed tolerance, blood stained stools or bloated stomach) which is often too late to prevent gut damage. Earlier diagnosis of gut disease may now be possible; calprotectin is produced when the gut is inflamed and can be found in faeces and blood. Calprotectin levels have been shown to be a reliable marker in diagnosing gut disease in premature infants. To date, calprotectin levels have not been monitored in infants with cardiac defects, who like premature infants are at high risk of gut disease but the cause of gut disease is different to that seen in premature infants and therefore requires specific monitoring. This study will implement a high risk feeding protocol which has been adapted from current feeding practices from the United States; the aim being to promote weight gain without increasing the risk of gut inflammation. Furthermore, the study will validate whether faecal calprotectin is a useful non-invasive marker in identifying gut disease in infants with cardiac defects. Currently, infants are diagnosed with necrotising enterocolitis by an abdominal X-ray (current 'Gold Standard'); infants who have a positive diagnosis will have faecal calprotectin levels cross-checked. From this data, cut-off values will be established which will provide data to diagnose necrotising enterocolitis eliminating the need for X-rays (radiation). Secondly, faecal calprotectin levels will be measured at strategic time points (longitudinal data) linked to increased risk of gut damage (following cardiac surgery and feeding) which will then be cross-checked against infants that developed NEC to identify whether high risk infants had raised calprotectin levels earlier.
Peripheral pulse oximetry allows continuous non-invasive measurement of arterial oxygen saturation, but the gold standard for arterial oxygen saturation is co-oximeter which requires an arterial blood sample. The purpose of this research study is to determine the accuracy of a pulse oximeter with a standard sensor (Masimo LNCS sensor) versus with the study sensors, namely Masimo blue sensor and Nellcor Max-I sensors and compared against co-oximetry. Currently available peripheral oximeters (standard) are inaccurate at low oxygen saturation noted in children with cyanotic heart disease. Hence therapeutic interventions (including surgery and cardiac catheterizations) based solely on peripheral oximetry can be delayed and or inadequate. By doing this study the investigators will be able to establish correct limits of peripheral pulse oximeter when using the standard and the study sensors.
