Evaluating Patient Tolerability for Urological Procedures Under Conscious Sedation: A Prospective Study.

OBJECTIVE

To prospectively evaluate patient-reported tolerability and surgical outcomes of urologic procedures with conscious sedation with or without local anesthesia. Administration of general or spinal anesthesia is associated with anesthetic-related complications, long wait times, and high costs. Using intravenous conscious sedation and/or local anesthesia is an emerging alternative for a myriad of urologic procedures.

METHODS

Patients were enrolled from June-August 2021 at a tertiary care hospital. All procedures were completed using fentanyl, midazolam, or both with patient and procedural data recorded upon completion. Patients were telephoned 4-6 weeks post-procedure with a standardized patient tolerability questionnaire. A multivariable adjusted logistic regression analysis was performed to evaluate whether a patient would opt for conscious sedation again as opposed to general anesthesia.

RESULTS

A total of 196 procedures were performed by 6 attending urologists with an overall success rate of 98.5% and 0% intraoperative complication rate. At 4-6 weeks follow-up, 85.6% of patients reported they would opt for conscious sedation as opposed to general anesthesia. Predictors of opting for conscious sedation in the future were older age (Odds Ratio (OR): 1.049; P = .017) and surgeon perceived level of patient tolerability (OR: 2.124; P <.001, scored 1-10).

CONCLUSION

Physician directed, nursing administered IV conscious sedation is a viable alternative for various urologic procedures and has minimal risk of perioperative complications.
