Summary
Patient-controlled sedation with propofol is safe and effective for extracorporeal shock wave lithotripsy (ESWL). Most patients reported satisfaction with this method for pain and sedation management during the procedure.
Area of Science:
- Anesthesiology
- Urology
- Pharmacology
Background:
- Extracorporeal shock wave lithotripsy (ESWL) requires effective sedation for patient comfort.
- Propofol offers rapid onset and offset, making it suitable for procedural sedation.
Purpose of the Study:
- To evaluate the efficacy and safety of patient-controlled sedation (PCS) with propofol during ESWL.
- To assess patient satisfaction with propofol-induced PCS.
Main Methods:
- A prospective clinical study involving 50 patients undergoing ESWL with an EDAP LT01 lithotriptor.
- Propofol was administered initially, followed by patient-controlled boluses with a lockout interval.
- Pain (VAS) and sedation levels were monitored, and patient satisfaction was recorded.
Main Results:
- The mean propofol dose was 147 ± 68 mg over a mean procedure duration of 47 ± 8 minutes.
- Mean maximal pain scores were 40 ± 20 mm on the VAS, with a median sedation score of 2 (drowsy).
- 83% of patients reported satisfaction or high satisfaction with PCS; no complications occurred.
Conclusions:
- Patient-controlled sedation with propofol is a safe and effective method for hypnotic agent administration during ESWL.
- PCS with propofol provides adequate sedation and pain control, leading to high patient satisfaction.
