Filter by:The objective of this project is to create deep learning and machine learning models capable of recognizing patient visual cues, including facial expressions such as pain and functional activity. Many important details related to the visual assessment of patients, such as facial expressions like pain, head and extremity movements, posture, and mobility are captured sporadically by overburdened nurses or are not captured at all. Consequently, these important visual cues, although associated with critical indices, such as physical functioning, pain, and impending clinical deterioration, often cannot be incorporated into clinical status. The study team will develop a sensing system to recognize facial and body movements as patient visual cues. As part of a secondary evaluation method the study team will assess the models ability to detect delirium.
The goal of this clinical trial is to investigate the effectiveness of sedation guided by the bispectral index (BIS) in reducing the incidence of delirium and the doses of sedative drugs used in critical patients who require deep sedation. The main questions this study aims to answer are: - Does sedation guided by BIS lead to higher delirium and coma-free days compared to clinical monitoring? - Does sedation guided by BIS result in reduced doses of sedative drugs compared to clinical monitoring? Participants in this study will be randomly assigned to one of two groups: Clinical Monitoring Group: Participants in this group will receive sedation based on clinical scales. These participants will also be fitted with a BIS sensor, but the sensor will be covered. Sedation Guided by BIS Group: Participants in this group will receive sedation guided by the bispectral index. The study will be conducted as a prospective, controlled, blind intervention trial with random distribution and intention to treat. The primary outcomes to be evaluated include: - Delirium and coma-free days after the end of deep sedation using the Confusion Assessment Method for the ICU (CAM-ICU) scale. - Total dose of sedative drugs administered. - BIS values Researchers will compare the two groups to determine if sedation guided by BIS is associated with a higher number of delirium and coma-free days, reduced sedative drug doses, and higher values of BIS compared to clinical monitoring.
Delirium is the most common neurological adverse outcome in elderly surgical patients. It is associated with an increased mortality and morbidity, including need for prolonged hospital stay and institutional care. Despite this, there are no effective preventive strategies. Melatonin is a hormone released from the pineal gland. It is used to improve sleep quality and to treat jet lag. Small studies have suggested that it can decrease the chances of delirium. Since the existing literature is small and uncertain, it is important to test its benefit in a large sample to help guide clinicians. This proposed trial is aimed at testing assessing the feasibility of a large, multi-center, randomized control trial to decrease the incidence of postoperative delirium.
This phase II/IIII trial studies how well haloperidol and lorazepam work in controlling symptoms of persistent agitated delirium in patients with cancer that has spread to other places in the body undergoing palliative care. Haloperidol and lorazepam may help in controlling symptoms of agitated delirium in patients with cancer and may lessen any distress that their caregivers may be experiencing.
Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common after surgeries in the elderly, especially after cardiothoracic surgery. These conditions are associated with adverse short- and long-term outcomes. Multiple conditions in the perioperative period have been proposed as risk factors of POD and POCD. Incidences vary across institutions due to differences in screening and diagnostic tools.
Delirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. The investigators hypothesize that, for elderly patients after orthopedic surgery, dexmedetomidine supplemented intravenous analgesia can reduce the incidence of delirium and improve the long-term outcomes.
Delirium is an acutely occurred and fluctuating cerebral dysfunction characterized with inattention, altered consciousness, cognitive decline and/or abnormal perception. It is common in the elderly after cardiac surgery and is associated with worse outcomes. Causes leading to delirium are multifactorial but sleep disturbances remains an important one. In previous studies, sedative-dose dexmedetomidine improves sleep quality in ICU patients with mechanical ventilation; and low-dose dexmedetomidine improves sleep quality in postoperative patients without mechanical ventilation. In recent studies of elderly after noncardiac surgery, night-time infusion of low-dose dexmedetomidine reduces delirium and improves 2-year survival. The investigators hypothesize that, for elderly patients after cardiac surgery, night-time infusion of dexmedetomidine may also improve sleep quality, reduce delirium development and improve 2-year survival.
Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.
Delirium is a frequent condition in the Intensive Care Unit (ICU) with no existing evidence-based treatment. The aim of the AID-ICU study is to assess the benefits and harms of haloperidol treatment for the management of ICU acquired delirium.
Postoperative delirium is a condition in which patients develop temporary difficulties in maintaining attention and thinking clearly. These new problems can appear after surgery and change throughout the day. This confusion can last several days. The overall purpose of this study is to measure brain activity during sleep and wakefulness to learn about their relationships to delirium after surgery. While participants may not feel like their normal self during the study, they are in the best position to help us learn how to improve the recovery of brain function and sleep in others having surgery. The investigators need to learn from those who have and have not become confused after their surgical procedure.
