Filter by:We plan to investigate the relationship between hypotensive epidural anesthesia for hip arthroplasty and cerebral oxygen saturation.
The purpose of this study is evaluate postoperative delirium after general anesthesia and regional anesthesia in elderly patients undergoing hip fracture surgery. Our research hypotheses are: (1) regional anesthesia may contribute to decrease the incidence of postoperative delirium. (2) Regional anesthesia may improve the outcome of elderly patient and reduce healthcare costs associated with postoperative delirium. (3) Postoperative delirium may result in poor long-term functional outcomes.
Children who receive general anesthesia may become agitated (emergence delirium) in the recovery period. This occurs more often after inhalational anesthetics, particularly sevoflurane and desflurane than after propofol. However, agitation after anesthesia in children may be difficult to distinguish from pain; accordingly studies are ideally designed during MRI to obviate the contribution of pain during emergence. Airway complications have been reported after LMA and isoflurane more commonly than with IV propofol and nasal prongs. Whether the airway complications were due to the LMA or the isoflurane was unclear. Therefore, this study was designed to study the incidence of 1. agitation after sevoflurane compared with IV propofol and 2. airway complications after LMA or nasal prongs.
Rationale: Pediatric Adenotonsillectomy is a common procedure of brief performed on a day-case basis, in which rapid recovery with safe airway after extubation is crucial. Sevoflurane is considered the inhaled anesthetic of choice in such procedures, however it has been reported that emergence agitation (EA) is a frequent complication in 30-80% of children receiving sevoflurane general anesthesia. The possible effect of magnesium sulphate on decreasing the incidence of EA in children was not adequately investigated. Objective: To assess the possible effects of intraoperative intravenous magnesium sulphate (MgSO4) infusion on the incidence of sevoflurane-induced EA in children undergoing adenotonsillectomy. Study population and sample size: Children 4-7 years, ASA physical status I or II, undergoing Adenotonsillectomy under sevoflurane general anesthesia. 64 patients (32/group) is required to detect a significance difference of 40% in the incidence of agitation between two groups, with a power of 80% and alpha error of 5%. Study design: A double blind, randomized, placebo controlled study. Method: In the placebo group, a normal saline bolus dose 0.3ml/kg will be iv infused followed by a continuous infusion of 0.1 ml/kg/h. In the MgSO4 group, a MgSO4 bolus dose 0.3mL/kg will be iv infused followed by a continuous infusion of 0.1 ml/kg/h. infusion terminated by the end of surgery. Post operative emergence agitation will be assessed by using the Pediatric Anesthesia Emergence Delirium scale. Possible risks: Drug side effects such as facial warmth, flushing, dry mouth, and malaise. Outcome parameters: The primary outcome: incidence of sevoflurane-induced EA measured using the Pediatric Anesthesia Emergence Delirium (PEAD). Secondary outcome: postoperative pain and rescue analgesic requirements, perioperative hemodynamics, durations of recovery, postoperative complications Statistical analysis plan: Student's t-test or Mann Whitney-U and Chi square or Fisher's exact tests will be used as appropriate. The possible relationship between EA and pain scores will be evaluated with the use of Spearman's rank correlation coefficient Time plan: 6-9 months.
The investigators are inviting your child to participate in this research study because your child is having myringotomy (putting a tiny incision in the eardrum with or without tube insertion) under general anesthesia. The purpose of this study is to determine whether a single injection of Dexmedetomidine (study medication) decreases the frequency of awaking from anesthesia frightened or agitated in children having myringotomy surgery as compared to those children who receive placebo (sterile saltwater).
To Determine The Efficacy of a Rapid Bolus Injection of Dexmedetomidine on the Incidence of Emergence Agitation in Anesthetized Children and the Cardiovascular Profile of a Rapid Bolus Injection of Dexmedetomidine.
This prospective, double blind, placebo-controlled, parallel group study will be conducted in three study centers in Guangzhou, China. Patients aged older than 65 (ASA I-III) undergoing primary elective abdominal surgery with general anesthesia will be involved in this study. According to previous studies and our pilot trial, the sample size was estimated to be 900 subjects (each center recruiting 300 patients). All eligible patients will be randomly assigned to one of two groups: study group receiving parecoxib and control group receiving normal saline. All patients will be managed with by a standard clinical anesthesia protocol with a sevoflurane-based general anesthesia with continuous intravenous remifentanil, followed by a postoperative PCA with morphine. The emergence delirium will be evaluated by two persons blinding to medication and grouping using Riker sedation-agitation scale immediately since tracheal extubation and at specific time points until patients being discharged from PACU. Pain intensity assessments and pain relief assessments will also be conducted by the patients at given time points in 2 days postoperatively. The morphine-sparing effect, tolerability and safety of parecoxib will be investigated as well.
The purpose of this study is to determine the incidence of pain, emergence delirium and the combination of those postoperative negative behaviours during the first 15 minutes after awakening from sevoflurane anesthesia in pre-school children. Additionally this study will evaluate the relationship between emergence delirium and postoperative pain behaviour after adenotonsil surgery.
Emergence delirium (ED) refers to a wide variety of behavioural disturbances that are commonly seen in children following emergence from anesthesia. ED can potentially be dangerous and have serious consequences for the child such as injury, increased pain, and dislodgement of medical devices, often requiring physical restraint or pharmacological control. Witnessing this behaviour can be stressful for parents, which can negatively affect their interaction with the healthcare system, and their relationship with the child, nursing staff and other healthcare providers. The investigators aim to minimize ED to reduce the distress experienced by patients and their parents. This study will compare the recovery profile of sevoflurane with that of propofol remifentanil and their associated incidence of ED. This study should enable us to determine which form of anesthesia is associated with the fewest incidences of ED in children.
Emergence delirium (ED) from general anesthesia posts risk and harm to pediatric population undergo general anesthesia. The purpose of the study is to compare the use of dexmedetomidine versus placebo in reducing the incidence and severity of ED in a pediatric neurosurgical population.
