Enteral vs. intravenous ICU sedation management: study protocol for a randomized controlled trial.

ABSTRACT: A relevant innovation about sedation of long-term Intensive Care Unit (ICU) patients is the 'conscious target': patients should be awake even during the critical phases of illness. Enteral sedative administration is nowadays unusual, even though the gastrointestinal tract works soon after ICU admission. The enteral approach cannot produce deep sedation; however, it is as adequate as the intravenous one, if the target is to keep patients awake and adapted to the environment, and has fewer side effects and lower costs.A randomized, controlled, multicenter, single-blind trial comparing enteral and intravenous sedative treatments has been done in 12 Italian ICUs. The main objective was to achieve and maintain the desired sedation level: observed RASS = target RASS ± 1. Three hundred high-risk patients were planned to be randomly assigned to receive either intravenous propofol/midazolam or enteral melatonin/hydroxyzine/lorazepam. Group assignment occurred through online minimization process, in order to balance variables potentially influencing the outcomes (age, sex, SAPS II, type of admission, kidney failure, chronic obstructive pulmonary disease, sepsis) between groups. Once per shift, the staff recorded neurological monitoring using validated tools. Three flowcharts for pain, sedation, and delirium have been proposed; they have been designed to treat potentially correctable factors first, and, only once excluded, to administer neuroactive drugs. The study lasted from January 24 to December 31, 2012. A total of 348 patients have been randomized, through a centralized website, using a specific software expressly designed for this study. The created network of ICUs included a mix of both university and non-university hospitals, with different experience in managing enteral sedation. A dedicated free-access website was also created, in both Italian and English, for continuous education of ICU staff through CME courses.This 'educational research' project aims both to compare two sedative strategies and to highlight the need for a profound cultural change, improving outcomes by keeping critically-ill patients awake.Clinicaltrials.gov #NCT01360346.

Project description:PurposeTo determine whether oral sedation is as safe and effective as IV sedation for ophthalmic surgeries other than cataract surgery, we tested whether patient satisfaction with oral triazolam was non-inferior to IV midazolam for cornea and glaucoma surgeries.Patients and methodsSeventy-five cornea and 49 glaucoma surgery patients 18 years and older at Boston Medical Center (Boston, MA) were randomized within each study group (cornea or glaucoma) to receive oral triazolam + IV placebo, or oral placebo + IV midazolam before surgery in a double-masked fashion. Supplemental IV anesthesia was administered as needed during surgery. The primary outcome measure was patient satisfaction with anesthesia, compared between oral and IV sedation groups via t-test for non-inferiority, based on 70 cornea and 43 glaucoma subjects completing the study. Secondary outcome measures included surgeon and anesthesia provider satisfaction with anesthesia, rate of supplemental IV anesthesia, and incidence of adverse events and surgical complications.ResultsUsing an a priori non-inferiority margin of 0.5, initial oral sedation was non-inferior to initial IV sedation in cornea (n=70, p<0.001) and glaucoma (n=43, p=0.017) groups, even after excluding subjects administered supplemental IV anesthesia. There were no significant differences in anesthesia provider or surgeon satisfaction, intra-operative complications, adverse events, or supplemental anesthesia between groups, except for higher anesthesia provider satisfaction with oral sedation in an Ahmed or Baerveldt implant ± cataract surgery sub-group (p=0.04). Subjects receiving supplemental anesthesia included 6 oral (18.2%) and 5 IV (13.5%) in the cornea group (p=0.59), and 7 oral (29.2%) and 6 IV (31.6%) in the glaucoma group (p=0.50).ConclusionOur results suggest that an initial dose of oral triazolam is equivalent to IV midazolam for non-cataract anterior segment surgeries. However, there was a relatively high need for supplemental IV anesthesia during some surgery types, particularly with glaucoma tube shunt implantation.

Project description:BackgroundUse of sedatives and analgesics is associated with the occurrence of delirium in critically ill patients receiving mechanical ventilation. Dexmedetomidine reduces the occurrence of delirium but may cause hypotension, bradycardia, and insufficient sedation. This substudy aims to determine whether the combination of esketamine with dexmedetomidine can reduce the side effects and risk of delirium than dexmedetomidine alone in mechanically ventilated patients.MethodsThis single-center, randomized, active-controlled, superiority trial will be conducted at The First Affiliated Hospital of Nanjing Medical University. A total of 134 mechanically ventilated patients will be recruited and randomized to receive either dexmedetomidine alone or esketamine combined with dexmedetomidine, until extubation or for a maximum of 14 days. The primary outcome is the occurrence of delirium, while the second outcomes include the number of delirium-free days; subtype, severity, and duration of delirium; time to first onset of delirium; total dose of vasopressors and antipsychotics; duration of mechanical ventilation; ICU and hospital length of stay (LOS); accidental extubation, re-intubation, re-admission; and mortality in the ICU at 14 and 28 days.DiscussionThere is an urgent need for a new combination regimen of dexmedetomidine due to its evident side effects. The combination of esketamine and dexmedetomidine has been applied throughout the perioperative period. However, there is still a lack of evidence on the effects of this regimen on delirium in mechanically ventilated ICU patients. This substudy will evaluate the effects of the combination of esketamine and dexmedetomidine in reducing the risk of delirium for mechanically ventilated patients in ICU, thus providing evidence of this combination to improve the short-term prognosis. The study protocol has obtained approval from the Medical Ethics Committee (ID: 2022-SR-450).Trial registrationClinicalTrials.gov: NCT05466708, registered on 20 July 2022.

Project description:BACKGROUND:Proximal humerus fractures are the third most common fracture in the elderly population and are expected to increase due to the aging population. Surgical fixation with locking plate technology has increased over the last decade despite a lack of proven superiority in the literature. Three previous randomized controlled trials have not shown a difference in patient-centered outcomes when comparing non-operative treatment with open reduction and internal fixation. Low patient enrollment and other methodological concerns however limit the generalizability of these conclusions and as a result, management of these fractures remains a controversy. By comparing the functional outcomes of locked plate surgical fixation versus non-operative treatment of displaced three and four-part proximal humerus fractures in the elderly population with a large scale, prospective, multi-centered randomized controlled trial, the optimal management strategy for this common injury may be determined. METHODS:We will conduct a prospective, single blind randomized controlled parallel arm trial to compare non-operative management of proximal humerus fractures with open reduction and internal fixation using locked plating technology. One-hundred and sixty patients > age 60 with acute 3- or 4- part proximal humerus fractures will be randomized to either open reduction and internal fixation with locked plating technology or non-operative management treatment arms. The primary outcome measure is the Constant Score at 24 months post-operative. Secondary outcome measures include the American Shoulder and Elbow Surgeon's Score (ASES), EuroQol EQ-5D-5 L Health Questionnaire Score, short form PROMIS upper extremity score and IPAQ for the elderly score. Further outcome measures include assessment of the initial classification, displacement and angulation and the quality of surgical reduction via a standard computed tomography (CT) scan; rates of non-union, malunion, arthrosis, osteopenia or other complications including infection, nerve injury, intra-articular screw penetration, reoperation rates and hospital re-admission rates. DISCUSSION:The results of this trial will provide Level 1 evidence to guide decision-making in the treatment of proximal humerus fractures in the elderly population.
