Summary

Patient-controlled sedation with propofol provided stable vital signs and satisfactory patient cooperation during third molar surgery. Most patients experienced amnesia for the procedure and reported high satisfaction, preferring self-administration for future dental procedures.

Area of Science:

  • Dental Surgery
  • Anesthesiology
  • Sedation Techniques

Background:

  • Patient-controlled sedation (PCS) offers tailored anesthesia.
  • Propofol is a widely used intravenous anesthetic agent.

Purpose of the Study:

  • To evaluate the efficacy and safety of patient-controlled sedation using propofol for third molar extractions.
  • To assess patient cooperation, satisfaction, and amnesia with this sedation method.

Main Methods:

  • Twenty-three ASA 1 patients undergoing surgical third molar extraction received propofol via patient-controlled sedation.
  • Cardiovascular and respiratory parameters were monitored throughout the procedure.
  • Sedation depth was assessed by eyelid closure and response to verbal commands.
  • Postoperative amnesia and patient satisfaction were evaluated.

Main Results:

  • Cardiovascular and respiratory stability were maintained during propofol sedation.
  • Sedation depth was generally light, with patients responsive to verbal commands.
  • Seventy percent of patients experienced amnesia for the extraction procedure.
  • Intra-operative cooperation was good, and postoperative patient satisfaction was high.
  • Propofol dose correlated significantly with procedure length and surgical difficulty (p < 0.010).

Conclusions:

  • Patient-controlled sedation with propofol is a safe and effective technique for third molar surgery.
  • This method ensures hemodynamic stability and patient comfort.
  • High patient satisfaction and preference for self-administration suggest its suitability for routine dental practice.
