Personalizing Preprocedural Sedation for Regional Anesthesia: a Randomized Trial and Qualitative Assessment of Patient-Centered Outcomes and Experience
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.
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.
