Active clinical trials for "Delirium"

The aim is to study the effectiveness of Quetiapine in preventing delirium in the elderly patients with multiple risks for delirium.

The aim is to evaluate the impact of visual projection of images of relatives or loved ones in patients undergoing cardiac surgery in the immediate postoperative period, and its influence on the incidence and development of postoperative delirium. A randomized, double-blind clinical trial was designed in the immediate postoperative period of adult patients undergoing cardiac surgery. CONSORT guidelines were followed. A control group and an intervention group were established. In the intervention group, the patients underwent a visual projection, while the usual unit treatment was carried out with the control group. Sociodemographic, anthropometric, anesthetic, and surgical variables were also recorded. The postoperative delirium assessment scale used was the "Confusion Assessment Method for the Intensive Care Unit scale" (CAM-ICU). The projection of visual material could reduce the incidence of postoperative delirium in patients undergoing cardiac surgery, although it cannot be established that it is effective as a treatment once the pathology is already established. The results obtained suggest that the visual projection of images is an effective and economical tool to address an increasingly incidental problem due to the aging of the population.

The purpose of this study is to assess the efficacy of dexmedetomidine versus propofol for prolonged sedation in trauma and surgical patients.

Myringotomy tube placement is one of the most commonly performed operations in children. Emergence delirium after such procedures is common. During emergence delirium children can become both a danger to themselves and others around them, including family members and hospital staff. The primary objective of this study is to determine if acupuncture, when used in combination with standard anesthetic management, decreases the incidence of emergence delirium in pediatric patients following myringotomy tube placement. Patients with and without premedication of midazolam will be included. A secondary objective of this study is to determine our institution's actual incidence of emergence delirium for this operation using a validated scale, the Pediatric Anesthesia Emergence Delirium (PAED) scale. We will also compare rates of emergence delirium in patients that received a premedication of midazolam versus (V) those that did not (NV). This is a randomized double-blinded trial. We will enroll 100 children aged 1-6 years old. Premedication with midazolam will be decided by the anesthesiologist. If needed, the patient will receive a standard does of oral midazolam plus acetaminophen (V). If the patient does not require premedication with midazolam, oral acetaminophen will be given alone (NV). Patients will then be randomized to receive either acupuncture with standard general anesthesia care (A) or to receive standard anesthetic care alone (S). Patients, their family members and recovery registered nurses (RNs) will not know if acupuncture was performed. Intraoperative anesthetic techniques will be standardized and include inhaled inductions with nitrous oxide and sevoflurane. Anesthesia maintenance will be inhaled sevoflurane and the usual pain medication ketorolac will be given intramuscularly prior to emergence. Acupuncture needles will be placed after anesthesia induction and removed prior to leaving the operating room. A total of 4 needles will be placed, one in each wrist at the Heart 7 (HT7) point and one in each ear at the Shen Men point. The needles will be inserted bilaterally to a depth of 1.8 mm. In the PACU, a blinded study observer will evaluate the patient at four time points using the PAED scale: time of awakening and 5, 10 & 15 minutes after awakening. Follow up phone calls will be made one day and one week after surgery. Families will be asked about behavior after discharge, sleep and bed-wetting.

The purpose of this study is to determine whether the incidence of emergence delirium will be reduced when end-tidal concentration of sevoflurane decreases.

Sevoflurane with its rapid induction and emergence, hemodynamic stability, and nonirritating airway properties, has acquired widespread acceptance in children. However, sevoflurane has been reported to be associated with emergence agitation in children, with a reported incidence of up to 80%. The purpose of this study is to verify that the prophylactic use of midazolam, which is a GABA A receptor inhibitor, given five minutes before the end of strabismus surgery reduces the incidence of emergence agitation after sevoflurane anesthesia in children. Simultaneously, this study aims to find out the proper dose of midazolam with minimum disturbance to patient's emergence time.

Assessment of sedative effects of sevoflurane, dexmedetomidine and propofol on the clinical course of delirium, SIRS and neuroinflammation in mechanically ventilated patients using CAM-ICU scale, GSK-3beta and protein S100b in serum.

Reconstruction using microvascular free tissue flap has been an important management in patients with maxillofacial tumor. It is often characterised as long operation time, more traumatic and require restriction of patient's head movement postoperatively in order to prevent disruption of microvascular anastomosis. Agitation and delirium are common in patients with free flap surgery, which may lead to serious consequences such as self extubation, injury or even failure of the flap. Dexmedetomidine is a sedative and co-analgesic drug with high specificity for α2-adrenoceptor. It is widely used in ICU sedation in general hospital. However its use after free flap surgery is not well documented. Furthermore the effect of Dexmedetomidine on preventing delirium has not been proved. The investigators hypothesized that the use of Dexmedetomidine would reduce emergence agitation and prevent delirium in patients after free flap surgery.

This study is trying to see if using precedex pre-operatively prevents emergence delirium in pediatric (ages 1-7) patients undergoing strabismus surgery.

Delirium is a serious medical condition associated with increased mortality, longer hospital stay, increased rates of institutionalisation, and declines in post-admission functionality. Despite the prognostic utility of diagnosing delirium and its utility as an important indicator of health quality in elderly patients in developed countries, it is not routinely screened for in many busy general medical in-patient settings, especially in developing countries. Unpublished data from a recent study of general medical in-patients in Groote Schuur Hospital, Cape Town, South Africa, found that no patients admitted during an 8-week period received any formal cognitive testing or had documentation of the presence/absence of delirium in routine clinical notes. This under-recognition is largely the result of the length and complexity of available delirium diagnostic tools e.g. Mini-mental state exam (MMSE), although the perceived lack of clinical importance and conflicting results about specific treatment modalities also contribute. The investigators recently developed the simple 4-question "RACY" delirium screening tool for use in general medical in-patients. Preliminary data show the test to be simple and effective with a sensitivity and specificity of 78% and 85% respectively using a ROC-selected cut-point of RACY≤2. The investigators hypothesis that the RACY screening tool has the potential to be a simple and effective bedside delirium diagnostic instrument for use in non-geriatric, busy general medical in-patient settings. This study is a two-centre validation study to evaluate the diagnostic accuracy of this tool.
