Personalizing Preprocedural Sedation for Regional Anesthesia

Personalizing Preprocedural Sedation for Regional Anesthesia: A Randomized Trial and Qualitative Assessment of Patient-Centered Outcomes and Experience
This is a prospective, randomized study in patients who receive a nerve block prior to surgery.
The aim is to investigate whether individual differences in psychosocial and pain profiles may play a role in how patients experience sedation for regional anesthesia.
The study will utilize a mixed-methods approach, including a randomized controlled intervention and semi-structured interviews, in order to systematically investigate the relationship between an individual patient's level of catastrophizing and efficacy of procedural sedation, while exploring patient satisfaction with the preoperative nerve block experience.

Detailed Description
The primary quantitative outcome will be pain severity during nerve block placement.
Secondary quantitative outcome is patient satisfaction.
Validated psychometric assessment tools (pain catastrophizing scale) will be used to stratify patients according to baseline degree of pain catastrophizing (high versus low baseline pain catastrophizing).
These groups will then be randomized to receive either titrated pharmacologic sedation (i.e., additional midazolam and fentanyl beyond a standard low midazolam dose) or intraprocedural educational reassurance.
Semi-structured interviews and qualitative analysis will be used to explore patient's experiences with nerve block placement and identify themes regarding what makes this experience more positive or negative for individuals with different characteristics.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: High Pain Catastrophizing
Based on the Pain Catastrophizing Scale (PCS)
|
Prior to the start of the nerve block, patients in Arm 1 will receive titrated pharmacological sedation with IV midazolam with a goal of achieving moderate sedation.
If pain is felt despite subcutaneous lidocaine, IV fentanyl may be administered with a goal of achieving moderate sedation with analgesia.
Other Names:
Patients in the nonpharmacologic group will receive intraprocedural education and reassurance without pharmacologic sedation.
They will have the option to receive more pharmacologic sedation at any point during the nerve block (cross-over to titrated sedation group).
|
Experimental: Low Pain Catastrophizing
Based on the Pain Catastrophizing Scale (PCS)
|
Prior to the start of the nerve block, patients in Arm 1 will receive titrated pharmacological sedation with IV midazolam with a goal of achieving moderate sedation.
If pain is felt despite subcutaneous lidocaine, IV fentanyl may be administered with a goal of achieving moderate sedation with analgesia.
Other Names:
Patients in the nonpharmacologic group will receive intraprocedural education and reassurance without pharmacologic sedation.
They will have the option to receive more pharmacologic sedation at any point during the nerve block (cross-over to titrated sedation group).

Measure Description |
Time Frame |
---|---|---|
Pain scale
Time Frame: Immediately following procedure
|
Procedural pain rating during the nerve block procedure on a 0 (no pain) to 10 (severe pain) Likert scale.
