Filter by:Effectiveness of BIPAP is evaluated in Type-2 failure but evaluation of effectiveness of CPAP in Type-2 respiratory failure in post cardiac surgery patients was not done. So the objective of this study is to determine the acute effects of BIPAP vs. CPAP with conventional physiotherapy on Hemodynamics and Respiratory parameters in management of Type 2 Respiratory failure in post cardiac surgery patients.
Respiratory volume monitor (RVM) (ExSpiron) is superior to continuous pulse oximetry in detection of postoperative respiratory depression in high risk patients.
The execution of diagnostic-therapeutic investigations by bronchial endoscopy can expose the patient to acute respiratory failure (ARF). In particular, the risk of hypoxemia is greater during broncho-alveolar lavage (BAL). For this reason, oxygen therapy is administered at low or high flows during the course of bronchoscopic procedures, in order to avoid hypoxemia. Few clinical studies have demonstrated the efficacy and safety of high flow oxygen through nasal cannula (HFNC) during BAL procedures, and no study has evaluated, during bronchial endoscopy, the effects of HFNC on diaphragmatic effort (assessed with ultrasound) and aeration and ventilation of the different lung regions (assessed with electrical impedance tomography). Therefore, investigators conceived the present randomized controlled study to evaluate possible differences existing during bronchoscopy between oxygen therapy administered with HFNC and conventional (low-flow) oxygen therapy, delivered through nasal cannula.
To meet the unmet need of better and safer pain relief for acute pain in the post-operative setting, a Vital-signs-integrated Patient-assisted Intravenous opioid Analgesia ("VPIA") Delivery System, with novel and intelligent software algorithms and specialised hardware was developed. In the previous project, the investigators have shown that this system has the potential to increase the safety and patient satisfaction with intravenous opioid analgesia. However, opportunities to develop more robust vital signs monitoring with the goal of ensuring continual and effective analgesia are identified. The primary aim of this proposal is to advance the development of technology (through new features and functionality) and perform clinical evaluation of the VPIA system with a larger sample size to show improvements in patient's satisfaction (pain relief) and robustness of system in terms of vital signs integration. Novel technology using adaptive vital signs controller, integrated with an infusion pump and single finger probe vital signs monitor system will be developed with the aim for commercialisation.
Tramadol is opioid analgesic widely used to treat moderate to severe pain. It is metabolized by cytochrome CYP2D6 into two major metabolites: pharmacologically active metabolite O-desmethyltramadol (M1) and inactive N-desmethyltramadol (M2), respectively. Tramadol kinetics in a population of patients undergoing major abdominal surgical procedures, and in patients with a greater or lesser degree of organic failure, is still not well researched. The investigators will measure plasma concentrations of tramadol and its metabolites after usual tramadol doses in ICU patients after major abdominal surgery. Also analgesic affect and side effect of tramadol will be recorded.
The purpose of this study is to explore and compare VRH after administration of Belbuca, Oxycodone HCl and Placebo in recreational opioid users. This is a single-center, double -blind, double-dummy , placebo-controlled randomized crossover study in up to 18 men and women self identifying as recreational users. This study will consist of a screening phase, treatment phase (which includes the Naloxone Challenge test) and follow-up visit.
The mortality burden of trauma in the United States is substantial, and is currently the leading cause of death in warfare and in civilians below age 45. Infection and sepsis are leading causes of morbidity and death in early survivors. Pneumonia (PNA) occurs in 17-36% of ventilated trauma patients; far more than non-trauma patients. The long held dogmatic notion of a mechanical predisposition to development of pneumonia in trauma has lacked robust support. However, there is evidence of the innate immune response to injury plays a major role in increasing susceptibility to infection. This application is for support of a Focused Program Award addressing the role that "danger signaling" due to "danger associated molecular patterns" (or DAMPs) derived from somatic tissue injuries play in altering innate immune signaling in the lung in ways that predisposes to PNA. This innate immune response plays a pivotal role in the development and progression of lung inflammation. The organization of the Focused Program Award is into six Projects with collaborators from the Departments of Surgery, Medicine and Anesthesiology at Beth Israel Deaconess Medical Center; the Department of Surgery at Brigham and Women's Hospital and the Departments of Biology and Biological Engineering at Massachusetts Institute of Technology. The human subjects interaction portion of this project is covered in the Human Subjects & Samples Project of the Award, although the information and tissues obtained from this Project will be shared with the other Projects, and the activities planned for those Projects are outlined in this application.
Around 20% of the patients requiring hospitalization for Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) develop hypercapnia, which is associated with an increased risk of death. Once Non Invasive Ventilation (NIV) has been initiated, a reduction in Respiratory Rate (RR) and improvement in pH within 4 h predicts NIV success. If pH <7.25 and RR >35 breath per minutes persist, NIV failure is likely. Worsening acidosis, after initial improvement with NIV, is also associated with a worse prognosis. In addition, it has been shown that delaying intubation in patients at high risk for NIV failure has a negative impact on patient survival. Hence, assessing the risk of NIV failure is extremely important. NIV has some limitations: a) intolerance, discomfort and claustrophobia requiring frequent interruptions; b) poor patient-ventilator synchrony, especially in presence of air leaks or high ventilatory requirements. Since removing carbon dioxide by means of an artificial lung reduces the minute ventilation required to maintain an acceptable arterial partial pressure of carbon dioxide (PaCO2), the investigators hypothesize that applying Extra-Corporeal CO2 Removal (ECCO2R) in high-risk AECOPD patients may reduce the incidence of NIV failure and improve patient-ventilator interaction. After the beginning of ECCO2R, NIV could be gradually replaced by High Flow Nasal Cannula Oxygen Therapy (HFNCOT), potentially reducing the risk of ventilator induced lung injury, improving patient's comfort and probably allowing the adoption of a more physiologically "noisy" pattern of spontaneous breathing.
Clinical reasoning and recent data suggest that early use of venovenous extracorporeal membrane oxygenation in refractory respiratory failure may confer a survival advantage. This retrospective matched study will assess whether patients who received VV ECMO at less severe hypoxaemia had differing outcomes to those who received ECMO with very severe hypoxaemia.
This is an observational study of outcomes of the NHS England-commissioned national respiratory ECMO service, which has been active at six centres since December 2011. The primary outcome of interest is the number of patients who survive to ICU discharge at the ECMO centre. The study also aims to identify factors predictive of outcome.
