Summary
Patients safely controlled their own propofol sedation for dental surgery using a target-controlled infusion (TCI) system. This patient-controlled sedation approach proved effective and highly satisfactory for minor oral procedures.
Area of Science:
- Anesthesiology
- Sedation Techniques
- Patient-Controlled Analgesia
Background:
- Target-controlled infusion (TCI) allows for precise drug delivery.
- Patient feedback can optimize sedation levels.
- Propofol is commonly used for procedural sedation.
Purpose of the Study:
- To evaluate a system enabling patients to self-administer propofol sedation via TCI.
- To assess the safety and efficacy of patient-controlled sedation for minor oral surgery.
Main Methods:
- 50 healthy adults undergoing minor oral surgery under local anesthesia participated.
- Patients were instructed on using the TCI system to manage their own sedation.
- Key outcomes included operating conditions, sedation depth, vital signs, and patient satisfaction.
Main Results:
- Good to fair operating conditions were reported in all patients.
- Sedation was achieved at a median target blood concentration of 2 mcg/ml, with no oversedation.
- High patient satisfaction (86% felt relaxed, 92% willing to repeat) and stable vital signs were observed.
Conclusions:
- Patient-controlled TCI of propofol provides a safe and effective sedation method for dental procedures.
- This technique integrates TCI benefits with patient feedback for enhanced procedural comfort.
- The system demonstrated high patient acceptance and safety for minor oral surgery.
