Remimazolam tosylate's long-term sedative properties in ICU patients on mechanical ventilation: effectiveness and safety.

ABSTRACT:

Objective

This study compared remimazolam tosylate with propofol or midazolam to assess its safety and effectiveness for long-term sedation of intensive care unit (ICU) patients requiring mechanical ventilation.

Methods

Adult patients in the ICU receiving sedation and mechanical ventilation for longer than 24 h were included in this single-center, prospective, observational study. Depending on the sedatives they were given, they were split into two groups (midazolam or propofol group; remimazolam group). ICU mortality was the main result. Laboratory tests, adverse events, and the length of ICU stay were considered secondary outcomes.

Results

A total of 106 patients were involved (46 received propofol or midazolam versus 60 received remimazolam). Age (P = 0.182), gender (P = 0.325), and the amount of time between being admitted to the ICU and receiving medication infusion (P = 0.770) did not substantially differ between the two groups. Multivariate analysis revealed no statistically significant difference in ICU mortality between the two groups. The remimazolam group showed less variability in heart rate (P = 0.0021), pH (P = 0.048), bicarbonate (P = 0.0133), lactate (P = 0.0002), arterial blood gas analyses, liver, and kidney function. The Richmond Agitation and Sedation Scale scores, length of ICU stay, and occurrence of adverse events did not exhibit significant differences between the two groups.

Conclusion

Remimazolam tosylate did not increase the total inpatient cost, the incidence of adverse events, and ICU mortality in patients with mechanical ventilation. These findings suggest that remimazolam may represent a promising alternative for sedation in the ICU setting.

Project description:BackgroundThe probability of weaning and of long-term survival of chronically mechanically ventilated cancer patients is unknown, with incomplete information available to guide therapeutic decisions. We sought to determine the probability of weaning and overall survival of cancer patients requiring long-term mechanical ventilation in a specialized weaning unit.MethodsA single-institution retrospective review of patients requiring mechanical ventilation outside of a critical care setting from 2008 to 2012 and from January 1 to December 31, 2018, was performed. Demographic and clinical data were recorded, including cancer specifics, comorbidities, treatments, and outcomes. Overall survival was determined using the Kaplan-Meier approach. Time to weaning was analyzed using the cumulative incidence function, with death considered a competing risk. Prognostic factors were evaluated for use in prospective evaluations of weaning protocols.ResultsBetween 2008 and 2012, 122 patients required mechanical ventilation outside of a critical care setting with weaning as a goal of care. The cumulative incidence of weaning after discharge from the intensive care unit was 42% at 21 days, 49% at 30 days, 58% at 60 days, 61% at 90 days, and 61% at 120 days. The median survival was 0.16 years (95% CI, 0.12 to 0.33) for those not weaned and 1.05 years (95% CI, 0.60 to 1.34) for those weaned. Overall survival at 1 year and 2 years was 52 and 32% among those weaned and 16 and 9% among those not weaned. During 2018, 36 patients at our institution required mechanical ventilation outside of a critical care setting, with weaning as a goal of care. Overall, with a median follow-up of 140 days (range, 0-425 days; average, 141 days), 25% of patients requiring long-term mechanical ventilation (9 of 36) are alive.ConclusionsCancer patients can be weaned from long-term mechanical ventilation, even after prolonged periods of support. Implementation of a resource-intensive weaning program did not improve rates of successful weaning. No clear time on mechanical ventilation could be identified beyond which weaning was unprecedented. Short-term overall survival for these patients is poor.

Project description:Rationale: In patients who are mechanically ventilated, diaphragm thinning on ultrasound is thought to correlate with diaphragm atrophy and has been associated with prolonged intubation. Factors other than atrophy, however, may cause changes in diaphragm thickness, which may confound studies examining changes in diaphragm thickness over time. Objectives: To determine if changes in the mode of mechanical ventilation or an interruption of sedatives have immediate effects on diaphragm thickness measurements in adult patients in the intensive care unit who are mechanically ventilated. Methods: Adult patients receiving invasive mechanical ventilation for less than 48 hours were included. Diaphragm thickness was measured at end-expiration and peak inspiration using ultrasound while patients were receiving both volume assist-control and pressure-support modes in a randomized crossover fashion. In patients receiving sedatives, additional measurements were taken after an interruption of sedatives. Measurements were compared between modes and on assist-control before and after an interruption of sedatives. Results: Of 85 patients enrolled, 66 had measurements on assist-control and spontaneous modes, and 40 had measurements before and after an interruption of sedatives. End-expiratory diaphragm thickness increased by a median of 0.08 mm after an interruption of sedatives (95% confidence interval [CI], 0.002 mm to 0.164 mm; P = 0.017), corresponding to a median increase of 6.5%. No difference was seen when comparing measurements taken on volume assist-control and pressure support (median difference, 0 mm; 95% CI, -0.07 mm to 0.08 mm; P = 0.98). Conclusions: End-expiratory diaphragm thickness increased by 6.5% after an interruption of sedatives. The effect of sedatives on measured diaphragm thickness should be considered in future studies examining changes in diaphragm thickness over time. Clinical trial registered with Clinicaltrials.gov (NCT04319939).
