Summary
Buffered local anesthetics significantly reduce injection pain during septorhinoplasty. This method offers a less painful, faster-acting anesthesia with no compromise on surgical outcomes.
Area of Science:
- Anesthesiology
- Plastic Surgery
Background:
- Pain during local anesthetic injection is a common patient concern.
- Septorhinoplasty procedures often require extensive local anesthesia.
Purpose of the Study:
- To evaluate patient-reported pain during septorhinoplasty using buffered versus unbuffered local anesthetics.
- To assess the impact of buffering on anesthetic efficacy, including hemostasis and duration.
Main Methods:
- A comparative study involving twenty volunteers undergoing septorhinoplasty.
- Patients compared pain perception between buffered and unbuffered local anesthetic injections.
- Surgeons assessed hemostasis and anesthesia duration.
Main Results:
- 18 out of 20 patients reported significantly less pain with buffered anesthetics.
- No difference in hemostasis or duration of action was observed.
- Buffered solutions demonstrated a faster onset of action.
Conclusions:
- Buffering local anesthetics with sodium bicarbonate effectively reduces injection pain during septorhinoplasty.
- The buffered solution provides rapid onset and full efficacy without compromising surgical hemostasis or anesthetic duration.
