Analgesia-First Sedation in Trauma Patients

Detailed Description
A significant proportion of patients admitted to the intensive care unit (ICU) require mechanical ventilation (MV). To facilitate care and maintain comfort for patients requiring MV, the utilization of a large quantity of sedatives and analgesics is required with either continuous infusion or intermittent dosing. However, prolonged continuous administration of sedatives and analgesics can contribute to prolonged MV. Numerous studies have shown that instituting protocol-directed sedation (PDS) by continuous infusion of sedatives and analgesics using a protocol that includes a daily interruption (DI) of the sedative will improve MV outcomes, specifically the duration of MV.
Protocol-directed sedation and daily sedation interruption:
Brook AD et al. performed a randomized, single-center, clinical trial; comparing protocol-directed sedation versus non-protocol-directed sedation in 321 mechanically ventilated patients. They included patients greater than the age of who were admitted to the medical intensive care unit. Based on randomization, 162 patients received protocol-directed sedation and 159 patients received non-protocol-directed sedation. The primary outcome measure was the duration of mechanical ventilation and secondary outcomes included: the length of ICU and hospital stay. The results revealed a reduction in the mean duration of mechanical ventilation for the protocol-directed sedation group (89.1 ± 133.6 hrs vs. 124.0 ± 153.6 hrs; p = .003). In addition, the protocol-directed sedation group had a reduced length of stay in the intensive care unit and hospital {5.7 ± 5.9 days vs. 7.5 ± 6.5 days (p = .013) and 14.0 ± 17.3 days vs. 19.9 ± 24.2 days (p < .001); respectively}. The protocol-directed sedation group (n = 66) had a reduced duration of continuous intravenous sedation (3.5 ± 4.0 days vs. 5.6 ± 6.4 days; p = .003). Brook's study demonstrated the clinical benefits of having protocol-directed or nurse-directed sedation in the medical intensive care unit. Since the study only involved patients in the medical intensive care unit, it is uncertain if the results are applicable to patients in the surgical unit.
Kress JP, et al. performed a randomized, single-center, clinical trial to evaluate daily interruption of continuous infusion of sedation in 128 mechanically ventilated adult patients. Notable exclusion criteria included patients already on sedative agents upon transfer to the ICU and admission due to resuscitation from cardiac arrest. The primary endpoints of the study included: the duration of mechanical ventilation, the length of stay in the intensive care unit, and the length of stay in the hospital. Total doses of sedatives (i.e. midazolam, propofol) and analgesic agents (i.e. morphine) were additional measured outcomes. Results from the study revealed a reduction in the median duration of mechanical ventilation for the daily interrupted group (4.9 vs. 7.3 days, p=.004). In addition, there was a reduction in the median length of stay in the ICU and hospital (6.4 vs. 9.9 days, p=.02 and 13.3 vs. 16.9 days, p=0.19; respectively). The total dose of midazolam was lesser in the daily interruption group (229.8 vs. 425.5 mg; p=.05). The study found no difference in regard to the incidence of self-extubation. Kress' study showed positive clinical outcomes with DI in the medical intensive care unit. However, many clinicians are concerned with the risk-related complications from DI (i.e. posttraumatic stress disorder and enhanced catecholamine response leading to cardiac complications). The study did contain limitations: it was limited to a single center and only included patients that were admitted to the medical intensive care unit. Thus, it is not clear if the results can be reproduced in other centers or applied to critically-ill surgical patients. Additionally, there was no mention of the use of PD-SBTs
Can analgesia first effectively facilitate mechanical ventilation for critically ill patients?
Strøm T et al evaluated the analgesia first in critically ill patients requiring mechanical ventilation. This was a randomized controlled trial involving 140 patients who were assigned in a 1:1 ratio to no sedation with analgesia (analgesia-first) group or sedation with DI group. The analgesia-first group or intervention arm received analgesics for pain control and sedation only if the analgesia-first approach failed. The intervention arm had significantly more days without ventilation (13.8 days ± 11.0 vs. 9.6 ± 10.0; p=0.0191) and shorter ICU days and hospital days. No difference was recorded in the occurrences of accidental extubations, but delirium was significantly higher in the analgesia-first group (20% vs. 7%, p=0.04).
Conclusion:
A literature search did not reveal any published studies demonstrating whether trauma patients should be managed with an AFS approach. This study will evaluate mechanical ventilation and ICU outcomes associated with the AFS approach to facilitate mechanical ventilation in critically ill patients. All patients will be managed with institutional-approved PDS-DSI or AFS protocols in the ICU.
- Rationale for the study
A limited number of randomized controlled trials:
Using the terms sedation and analgesia, mechanical ventilation discontinuation/weaning, critically ill, and trauma adult patients, a literature review was conducted to identify peer-reviewed articles in MEDLINE (1966-November 2021). Articles reviewed included those published in the English language, review articles, and trials with an emphasis on prospective, randomized, double-blind, placebo-controlled clinical trials. Reference citations were reviewed as an additional resource. The literature search revealed no studies that included the implementation of an AFS in trauma patients.
Which approach is preferred? There are no published studies demonstrating whether patients should be on AFS versus PDS-DSI for the management of trauma patients requiring mechanical ventilation beyond 48 hours.
How will this trial help? - Literature review
The above-mentioned literature review and search revealed no studies that included the implementation of an AFS versus PDS-DSI in ICUs. In addition, under these circumstances, it is uncertain if an AFS allowing minimal sedation is as efficacious and safe in comparison to a PDS-DSI.
- Use of trial results
The results of this study are clinically and economically relevant. The clinical data will provide information on what is the preferred sedation practice during mechanical ventilation weaning. In addition, the study will support a multi-disciplinary approach to managing mechanically ventilated patients. The measured outcomes from the study will generate further research to improve patient outcomes, specifically in mechanically ventilated patients. The economic implications can be potentially derived from the length of ICU or hospital stay.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Analgesia First Sedation
Subjects will be randomized to receive analgesia-first sedation by intermittent doses of Fentanyl (25 mcg), instead of continuous IV infusions.
If the intermittent IVP x4 fails to achieve the target pain score, an infusion starts at 50 mcg/hr and titration by 25 mcg q15 minutes.
If sedation score is not achieved, propofol infusion starts at 5 mcg/kg/min to achieve goal RASS of 0 to -2.
Subjects will be assessed for a ventilator weaning trial daily.
|
The Intervention is using a sedation strategy for MV trauma that initially targets pain by intermittent boluses followed by an IV drip only if required.
Sedatives are limited to agitation management and for a limited duration as needed.
This "analgo-sedation" approach differs from the approach of using IV drips of analgesics and sedatives simultaneously and discontinuing both once daily to assess subjects.
|
Active Comparator: Protocol Directed Sedation and Daily Sedation Interruption
Subjects will receive Fentanyl for analgesia and midazolam for sedation management.
The RASS score is used to guide sedation to a goal of 0 to -2 and daily sedation by IV Midazolam at 1 mg/hr and titrated by 1 mg/hr q60 mins.
Midazolam boluses are allowed by 1 mg IVP q5 mins x2 before increasing the infusion rate.
Propofol and dexmedetomidine are permitted under existing institutional sedation protocol.
Fentanyl IV starts at 50 mcg/hr and is titrated by 25 mcg/hr q15 mins to achieve target pain score.
Fentanyl bolus of 25 mcg IVP q5 min x2 doses is given before increasing the infusion rate.
Daily sedation interruption (DSI) is performed daily and ventilator weaning trial if they pass.

The active comparator in this study is using a sedation strategy for MV trauma that uses IV drips of analgesics and sedatives simultaneously and discontinues both once daily to assess subjects.
