Filter by:Muscle atrophy and diaphragm dysfunction are common with prolonged mechanical ventilation (PMV). Electrical stimulation has been shown to be beneficial in severe chronic heart failure and chronic obstructive pulmonary disease. However, its effect on PMV is unclear. This study examined the effects of transcutaneous electrical diaphragmatic stimulation (TEDS) on respiratory muscle strength and weaning outcomes in patients with PMV.
Open heart surgeries are one of the major and complicated surgeries performed frequently in the world due to the prolongation of life expectancy and developments in medicine. As a result of these operations, not only the heart and vessels, but also all organs and systems depending on the systemic circulation are affected. Some biological inflammation markers have been determinant in determining cardiovascular risk. High neutrophil count was associated with increased mortality, while low lymphocyte count was a strong constant predictor of mortality. In addition, increased serum uric acid (UA) levels have been found to be associated with obesity, dyslipidemia, and hypertension, which is associated with cardiovascular disease risk. The aim of this study is to investigate the effects of patients who underwent coronary bypass surgery under elective conditions in Karadeniz Technical University Faculty of Medicine between 2008-2020 on in-hospital and 1-year mortality based on preoperative neutrophil / lymphocyte ratios and uric acid values.
Elderly patients have a higher incidence of morbidity and mortality due to the interaction of various factors such as decreased physiological reserves, concomitant comorbidities, multiple drug use, cognitive dysfunction, and frailty. Surgical stress, pain and associated lung complications are common problems in open heart surgeries that can affect morbidity and mortality. With a good postoperative pain control and improved respiratory mechanics, complications that may develop in patients can be significantly prevented, and the hospital cost can be reduced and the workforce loss of patients can be reduced by reducing the length of hospital stay in the intensive care unit. Thoracic epidural analgesia (TEA) is an anesthetic analgesia method that has positive effects on many organ systems as well as providing good pain control and is frequently used in open heart surgery. The aim of this study is to investigate the effects of TEA on postoperative respiratory mechanics in geriatric patients, based on analgesia levels, extubation times, length of stay in intensive care, arterial blood gases, morbidity and mortality.
For the infant participating the study, ventilator settings and respiratory variables will be recorded every day and exported to a specific computer using the Servo Record Viewer version 1.0 (Maquet Critical Care AB, Getinge, Gothenburg, Sweden). Collected data gives the value for peak inspiratory pressure (PIP), expiratory tidal volume (Vt), peak Edi, minimum Edi, measured respiratory rate (RR), neural respiratory rate (nRR) and percentage of backup breaths for each minute. All the ventilator data will be inspected and compared with the event logs recorded automatically from the ventilator, which includes all the alarm notification, mode and setting changes, cables connection and disconnection data. Data during disconnection of the Edi cable, malfunction or dislocation of Edi catheter will be excluded from the analysis. The mean values during each day will be computed for each ventilatory variables. If there is a change in the ventilatory setting parameters, we will choose the one which was applied for longer duration in the 24-hour time period. The following clinical characteristics will be collected from medical records: gestational age at birth, birth weight, gender, the time and amount of feeding, medication during the study days, desaturation events, bradycardia events, suction time and methods.
The main objective of the present study is to determine ICU and in-hospital mortality associated with COVID-19 infection and its independent predictors, in patients admitted to adult ICUs in Argentina with a requirement for mechanical ventilation. Secondary objectives include: determining epidemiological and clinical data in patients with COVID-19 disease; the associated morbidity, the support and therapeutic measures implemented, and the evolution of these patients upon discharge from the ICU. Likewise, characteristics of each ICU will be recorded, and a survey will be carried out on the management of the COVID-19 pandemic, which will require information on the additional availability of critical resources for the care of patients admitted to the ICU. Likewise, characteristics of the ICU and hospitals will be registered.
The aim of this study is to compare the diameter of accessory respiratory muscles in patients with respiratory diseases and patients without such diseases, and to determine whether there is a connection between the ultrasound-measured thickness of accessory respiratory muscles and time of mechanical ventilation, as well as whether there is a the connection between the measured thickness and the treatment outcome of patients in the Intensive Care Unit (ICU).
The COVID-19 pandemic has led to shortages of intravenous sedatives due to increased ICU patient admissions and greater use of mechanical ventilation. A shortage of sedatives is as concerning as a shortage of mechanical ventilators since critically ill patients require sedation for comfort and to tolerate mechanical ventilation. Anti-adrenergic medications are increasingly recognized for their role in sedation of critically ill patients. Propranolol is a plentiful and inexpensive, non-selective beta-adrenergic blocker with good penetration of the blood-brain barrier, which can reduce agitation and arousal. The study team published a single-centre retrospective study of 64 mechanically-ventilated patients which found the initiation of propranolol was associated with an 86% reduction in propofol dose and a roughly 50% reduction in midazolam dose while maintaining the same level of sedation. Propranolol has the potential to mitigate the threat posed by worldwide sedative shortages and improve critical care management of patients who require mechanical ventilation. This study seeks to evaluate whether the addition of propranolol to a standard sedation regimen reduces the dose of sedative needed in critically ill patients requiring mechanical ventilation. This study is an open-label randomized controlled trial, single-blinded with 1:1 allocation. Both arms will receive sedation according to usual intensive care unit practice with a sedative agent. The intervention arm will additionally receive enteral propranolol 20-60mg q6h titrated up over 24-48h until intravenous sedative doses have fallen to a minimal level (propofol <0.5mg/kg/h or midazolam <0.5mg/h) or the maximum dose of propranolol is reached. Intravenous sedative doses will be titrated downwards in response to sympatholysis produced by the propranolol, as evidenced by a decreasing heart rate or blood pressure. The control arm will receive sedation without the addition or propranolol. The primary outcome will be the change in primary sedative dose from baseline to Day 3 of enrollment. Analysis of the primary outcome will be a difference in differences; the change in sedative dose from baseline to Day 3 in the intervention group versus the same change in the control group. The Mann-Whitney U test will be used as a nonparametric test of independent samples for this outcome.
Central venous pressure (CVP) is characterized by a low-frequency pleural-dependent as well as a high-frequency cardiac pulsatile component. The aim of the study is to compare the low-frequency component of CVP with the esophageal pressure (Pes), as surrogate of pleural pressure, to estimate trans-pulmonary pressure (PL).
Chest radiography is the gold standard for confirming tracheal intubation. Bedside ultrasound can be a useful alternative. The investigators are conducting a multi-center, observational study from January 2019 to May 2020 (COVID-US Study) to determine the feasibility of tracheal and lung ultrasound in confirming endotracheal tube placement in the critically ill.
During surgery, researchers use different methods in respiratory equipment. In the study researchers examine the effects of these methods on intraocular pressure changes by looking at the intraocular nerve diameter. Then look at the effects of these effects on patients conscious functions by asking some questions.
