[Patient-controlled sedation with propofol for extracorporeal shock wave lithotripsy].
OBJECTIVE
Evaluation of patient-controlled sedation with propofol for extracorporeal shock wave lithotripsy (ESWL) using an EDAP LT01 lithotriptor.


METHODS
Prospective clinical study.


METHODS
Fifty consecutive patients, ASA I or II, aged 18-65 years.


METHODS
Patients received 50 mg of propofol five minutes before ESWL, then they self-administered 50 mg bolus doses of propofol with a ten minutes lock-out interval. Pain (1-100 mm VAS) and sedation (four points scale) were assessed every five minutes. Patient satisfaction was recorded at the end of the procedure. Pharmacokinetic simulation was done with the Marsh's data set.


RESULTS
Three patients were excluded. Patients received a mean propofol dose of 147 +/- 68 mg during the procedure with a mean duration of 47 +/- 8 minutes. The median of the higher sedation scores was 2 (drowsy) and mean maximal VAS was 40 +/- 20 mm (10-70). No complications were recorded. Thirty-nine patients (83%) were satisfied or very satisfied by patient-controlled sedation.


CONCLUSIONS
Patient-controlled sedation with propofol is a safe and efficient mode of administration of an hypnotic agent for ESWL.
