Anesthesia Options in Plastic Surgery: General, Local, or Sedation?
Balancing comfort, hemodynamic control, and procedural scope, plastic surgeons select between general anesthesia, intravenous twilight sedation, and local infiltration.
Key points
- General Anesthesia: Standard for rhinoplasty, abdominoplasty, and breast surgery, providing total airway protection, complete muscle relaxation, and amnesia.
- Intravenous Sedation (Twilight Sleep): Administered via infusion; maintains spontaneous respiration in a deeply relaxed, dream-like state without endotracheal intubation.
- Local Anesthesia: Indicated for circumscribed procedures (blepharoplasty, otoplasty, hair transplantation) numbing exclusively the target anatomical field.
Clinical Algorithm Dictating Anesthetic Modality
The definitive choice balances anatomical airway safety, procedural duration, hemorrhage control, and patient anxiety. In rhinoplasty, cuffed endotracheal general anesthesia is mandatory to prevent blood aspiration into tracheobronchial trees. Conversely, during upper blepharoplasty, patient cooperation (opening/closing eyes for intraoperative symmetry checks) favors local anesthesia. The anesthetic blueprint represents an individualized consensus between the plastic surgeon and anesthesiologist.
Advances in TIVA (Total Intravenous Anesthesia) and Safety Monitors
Modern surgical suites increasingly utilize Total Intravenous Anesthesia (TIVA) in place of volatile inhalational gases. Target-controlled infusions of short-acting agents like propofol and remifentanil allow patients to awaken lucidly within minutes of surgery conclusion. Postoperative nausea and vomiting (PONV) are diminished by over 90%. Real-time Bispectral Index (BIS) electroencephalographic monitoring continuously quantifies anesthetic depth, entirely preventing intraoperative awareness.
