Certain diseases relating to the heart can only be definitively treated with surgery. When untreated, these can lead to heart failure with a lack of supply of oxygen-rich blood to the tissues, leading to damage to other organs. Adults who undergo heart surgery vary greatly in terms of age and relative health. This has significant implications when predicting outcomes in the aftermath of surgery. For example, a 90-year-old man with a variety of comorbidities such as diabetes and high cholesterol who requires a heart valve replacement may have an unfavourable chance of surviving the postoperative period when compared to an 18-year-old woman with no significant medical history undergoing the same procedure. Almost invariably, patients are admitted to an Intensive Care Unit (ICU) following heart surgery. This is done to facilitate close monitoring of the patients' vital organ functions and to also provide organ support if needed. For the heart, this can include the administration of drugs to help a heart pump forcibly, cause blood vessels to contract and increase blood pressure. Patients who have undergone heart surgery have been placed on a mechanical ventilator, following a tube placed in their windpipe. This form of ventilation often continues in ICU for a period of time, depending on the patient's condition. One specific type of ICU level monitoring that occurs in patients who have undergone heart surgery is cardiac output monitoring. This involves a thin tube, called a pulmonary artery catheter, that extends from the skin to the heart, via large blood vessels. Cardiac output monitoring is essential in this patient group to guide organ support and to provide information of how well the heart is functioning. In this observational study, the investigators wish to study patients who have undergone cardiac surgery, are receiving mechanical ventilation and have pulmonary artery catheters inserted. The investigators will collect cardiopulmonary data in these patients and compare these data with values of exhaled and inhaled gases (oxygen and carbon dioxide) over the same time period. This will enable the investigators to investigate the link between cardiopulmonary data and respired gas values. A better understanding of this link between cardiopulmonary function and oxygen/carbon dioxide values will then inform future studies aiming to determine the effect of various interventions in similar patient groups.
The investigators intend to assess the predictive value of early (first 48 hours) multimodal neuromonitoring parameters concerning late survival in critically ill intracerebral hemorrhage (ICH) patients.
Acute kidney injury (AKI) in Covid-19 patients is a topic that receives little attention in the literature, although being important in clinical practice in the ICU, particularly in Oman. Our objective was to determine the incidence of AKI, risk factors, and the requirement of renal replacement treatment. Methods: All adult patients hospitalized at Sultan Qaboos University Hospital in the critical care unit (ICU) between March 2020 and September 2021 with laboratory-confirmed Covid-19 had their medical records retrospectively reviewed. All patient characteristics, their course of events, and the treatment received in ICU were noted. The incidence of AKI, its association with the glycemic index, and other possible risk factors will be studied. Those requiring renal replacement therapy will be studied in terms of its predictors and outcomes.
High flow nasal cannula administration in critically ill patients is frequently used to improve acute respiratory failure or to prevent respiratory failure after extubation. It acts generating a mild positive pressure in the airways and by reducing respiratory effort of patients. However to the best of our knowledge, no study to date has directly measured the amount of positive pressure generated in the trachea of patients. The primary aim, therefore, of this study measures this positive pressure after extubation in critically ill patients.
The only supportive therapy for patients with AKI is renal replacement therapy (RRT). In the ICU setting, continuous RRT (CRRT) is mostly favored. In a post-hoc analysis of the RICH trial (regional citrate versus systemic heparin anticoagulation for CRRT in critically ill patient with AKI), it was shown that the filter life span is associated with an increased rate of new infection and that the type of anticoagulants did not directly affect infection rate. The mechanisms of this infection rate is unknown.
The purpose of this study is to evaluate the safety and feasibility of kefir administration in critically ill adults.
Intubation is a common procedure in the intensive care unit. Hypoxemia is the most frequent complication of this procedure. Monitoring the end-tidal of oxygen is recommended in operating room (OR). End-tidal of oxygen (EtO2) >90% is an indication of a correct preoxygenation. This monitoring is not used in routine in intensive care unit (ICU). There is no recommendation on the monitoring of end-tidal of oxygen in intensive care unit. In practice, clinicians use pulsed oxygen saturation (SpO2) to determine whether the patient is sufficiently preoxygenated. However, this parameter is not a good indicator of a correct preoxygenation. In the OR, patients are compliant during the preoxygenation period and the measure of EtO2 with the face mask monitor is considered reliable because i) mask leakage is minimal and ii) the patient can breathe slowly and regularly. Theses conditions are not available in critical ill patients requiring emergency intubation. EtO2 measured on the facemask may not reflect true EtO2. This concern about the reliability of EtO2 measurement via the facemask justifies that we conduct a study to compare EtO2 measured on a facemask (facemask EtO2) to EtO2 measured in pharynx (via e nasopharyngeal catheter). The aim of this study is to determine whether the measurement of EtO2 on facemask is reliable in patients in ICU.
In mechanically ventilated patients in intensive care unit, anemia is commonly seen and it is probably associated with adverse outcomes including mortality. We aim to investigate the impact of duration of anemia and the duration of mechanical ventilation as well as clinical outcomes in critically ill patients in intensive care unit who required ventilatory support >96 hr.
Objective: Test the ability of vibration to produce physiologic, biochemical, and anatomic changes consistent with exercise that would help prevent the development of muscle weakness that occurs when patients are immobile for long periods of time.
