Use of Continuous Regional Anesthesia Infusion as an Opioid-Sparing Modality in Mechanically Ventilated Patients With...

Area of Science:

• Critical Care Medicine
• Pain Management
• Anesthesiology

Background:

• Continuous regional anesthesia (CRA) is utilized for acute rib fracture analgesia.
• Evidence for CRA in mechanically ventilated (MV) patients with rib fractures is limited.
• This study evaluates CRA's impact on opioid use and MV liberation.

Purpose of the Study:

• To assess the effect of CRA on opioid consumption in MV patients with rib fractures.
• To determine if CRA influences the rate of liberation from MV in this patient cohort.

Main Methods:

• Retrospective study of MV patients with traumatic rib fractures (Jan 2022-July 2023).
• Patients received either CRA or standard care (non-CRA).
• Opioid consumption and MV liberation rates were compared pre- and post-intervention.

Main Results:

• The CRA group showed a significant decrease in opioid consumption 0-48 hours post-intervention compared to the non-CRA group.
• Specifically, opioid consumption decreased significantly at 0-24 hours (p=0.018) and 24-48 hours (p=0.001) post-CRA.
• No significant difference in liberation from MV was observed between the CRA and non-CRA groups.

Conclusions:

• CRA use is associated with reduced opioid requirements in mechanically ventilated patients with rib fractures.
• CRA did not facilitate earlier liberation from mechanical ventilation.
• The opioid-sparing effect of CRA is clinically relevant, warranting further investigation in larger prospective studies.
