The implementation of an analgesia-based sedation protocol reduced deep sedation and proved to be safe and feasible in patients on mechanical ventilation.

ABSTRACT: Deep sedation in critically ill patients is associated with a longer duration of mechanical ventilation and a prolonged length of stay in the intensive care unit. Several protocols have been used to improve these outcomes. We implement and evaluate an analgesia-based, goal-directed, nurse-driven sedation protocol used to treat critically ill patients who receive mechanical ventilation.We performed a prospective, two-phase (before-after), non-randomized multicenter study that involved 13 intensive care units in Chile. After an observational phase (observational group, n=155), we designed, implemented and evaluated an analgesia-based, goal-directed, nurse-driven sedation protocol (intervention group, n=132) to treat patients who required mechanical ventilation for more than 48 hours. The primary outcome was to achieve ventilator-free days by day 28.The proportion of patients in deep sedation or in a coma decreased from 55.2% to 44.0% in the interventional group. Agitation did not change between the periods and remained approximately 7%. Ventilator-free days to day 28, length of stay in the intensive care unit and mortality were similar in both groups. At one year, post-traumatic stress disorder symptoms in survivors were similar in both groups.We designed and implemented an analgesia-based, goal-directed, nurse-driven sedation protocol in Chile. Although there was no improvement in major outcomes, we observed that the present protocol was safe and feasible and that it resulted in decreased periods of deep sedation without increasing agitation.

Project description:BACKGROUND:Although routine administration of pharmacologic sedation or analgesia during mechanical ventilation in preterm neonates is not recommended, its use in clinical practice remains common. Alpha-2 agonists, mainly clonidine and dexmedetomidine, are used as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. Clonidine has not been systematically assessed for use in neonatal sedation during ventilation. OBJECTIVES:To assess whether clonidine administered to term and preterm newborn infants receiving mechanical ventilation reduces morbidity and mortality rates. To compare the intervention versus placebo, no treatment, and dexmedetomidine; and to assess the safety of clonidine infusion for potential harms.To perform subgroup analyses according to gestational age; birth weight; administration method (infusion or bolus therapy); dose, duration, and route of clonidine administration; and pharmacologic sedation as a co-intervention. SEARCH METHODS:We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 12) in the Cochrane Library, MEDLINE via PubMed (1966 to January 10, 2017), Embase (1980 to January 10, 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to January 10, 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials. SELECTION CRITERIA:We searched for randomized controlled trials, quasi-randomized controlled trials, and cluster trials comparing clonidine versus placebo, no treatment, or dexmedetomidine administered to term and preterm newborns receiving mechanical ventilation via an endotracheal tube. DATA COLLECTION AND ANALYSIS:For the included trial, two review authors independently extracted data (e.g. number of participants, birth weight, gestational age, all-cause death during initial hospitalization, duration of respiratory support, sedation scale, duration of hospital stay) and assessed risk of bias (e.g. adequacy of randomization, blinding, completeness of follow-up). This review considered primary outcomes of all-cause neonatal death, all-cause death during initial hospitalization, and duration of mechanical ventilation in days. MAIN RESULTS:One trial, which included 112 infants, met the inclusion criteria for this review. Term newborn infants on mechanical ventilation with the need for continuous analgesia and sedation with fentanyl and midazolam were eligible for enrollment during the first 96 hours of ventilation. Study authors administered clonidine 1 ?g/kg/h or placebo on day 4 after intubation.We found no differences between the two groups in all-cause death during hospitalization (risk ratio [RR] 0.69, 95% confidence interval [CI] 0.12 to 3.98). The quality of the evidence supporting these findings is low owing to imprecision of the estimates (one study; few events). The median (interquartile range) duration of mechanical ventilation was 7.1 days (5.7 to 9.1 days) in the clonidine group and 5.8 days (4.9 to 7.9 days) in the placebo group, respectively (P = 0.070). Among secondary outcomes, we found no differences in terms of duration of stay in the intensive care unit. Sedation scale values (COMFORT) and analgesia scores (Hartwig) during the first 72 hours of infusion of study medication were lower in the clonidine group than in the placebo group. AUTHORS' CONCLUSIONS:At present, evidence is insufficient to show the efficacy and safety of clonidine for sedation and analgesia in term and preterm newborn infants receiving mechanical ventilation.

Project description:IntroductionThis randomised, open-label, multicentre study compared the safety and efficacy of an analgesia-based sedation regime using remifentanil with a conventional hypnotic-based sedation regime in critically ill patients requiring prolonged mechanical ventilation for up to 10 days.MethodsOne hundred and five randomised patients received either a remifentanil-based sedation regime (initial dose 6 to 9 microg kg(-1) h(-1) (0.1 to 0.15 microg kg(-1) min(-1)) titrated to response before the addition of midazolam for further sedation (n = 57), or a midazolam-based sedation regime with fentanyl or morphine added for analgesia (n = 48). Patients were sedated to an optimal Sedation-Agitation Scale (SAS) score of 3 or 4 and a pain intensity (PI) score of 1 or 2.ResultsThe remifentanil-based sedation regime significantly reduced the duration of mechanical ventilation by more than 2 days (53.5 hours, P = 0.033), and significantly reduced the time from the start of the weaning process to extubation by more than 1 day (26.6 hours, P < 0.001). There was a trend towards shortening the stay in the intensive care unit (ICU) by 1 day. The median time of optimal SAS and PI was the same in both groups. There was a significant difference in the median time to offset of pharmacodynamic effects when discontinuing study medication in patients not extubated at 10 days (remifentanil 0.250 hour, comparator 1.167 hours; P < 0.001). Of the patients treated with remifentanil, 26% did not receive any midazolam during the study. In those patients that did receive midazolam, the use of remifentanil considerably reduced the total dose of midazolam required. Between days 3 and 10 the weighted mean infusion rate of remifentanil remained constant with no evidence of accumulation or of a development of tolerance to remifentanil. There was no difference between the groups in SAS or PI score in the 24 hours after stopping the study medication. Remifentanil was well tolerated.ConclusionAnalgesia-based sedation with remifentanil was well tolerated; it reduces the duration of mechanical ventilation and improves the weaning process compared with standard hypnotic-based sedation regimes in ICU patients requiring long-term ventilation for up to 10 days.

Project description:IntroductionFrom previous studies of pharmacodynamic data in mice, rats, beagle dogs and mini pigs, frequently in direct comparison to induction doses of propofol, ciprofol produced a rapid onset of anesthesia/sedation.MethodsA phase 1 study suggested potential clinical advantages of ciprofol as a sedation/anesthetic agent, with no evidence of drug-related toxicity. However, the sedation effects and safety of ciprofol in intensive care unit (ICU) patients with mechanical ventilation should be further confirmed in a phase 3 study with a larger cohort of patients. During a phase 3, non-inferiority, multicenter, single-blind, randomized, propofol controlled trial, Chinese ICU patients undergoing mechanical ventilation and requiring endotracheal intubation will be sedated for 6-24 h after randomization. Considering a success rate for ICU sedation of 99% for ciprofol and the positive control drug propofol, a total sample size of 120 subjects with mechanical ventilation will be required to achieve 80% power to determine non-inferiority with a margin of 8%. Finally, taking into account 10% losses, 135 patients will be enrolled and randomly assigned to ciprofol (90 cases) and propofol (45 cases) groups in a 2:1 ratio. The primary outcome will be the success rate of sedation satisfied by the following conditions: the time within the range of Richmond Agitation and Sedation Score (+ 1 ~ - 2) must account for ≥ 70% of the study drug administration time and without other rescue treatments. Secondary outcomes will include the average time to reach the sedation goal, study drug usage, rescue medication given per unit weight, extubation time, recovery time to full consciousness and nursing scores. Safety endpoints will include adverse events (AEs), drug related AEs and serious AEs.Planned outcomesThe results of this study will provide crucial information on the use of ciprofol for sedation of patients in ICUs.Trial registrationClinicalTrials.gov identifier, NCT04620031.
