Conscious Sedation in Implantology
What it is
Conscious sedation is a pharmacological technique that uses anxiolytics or hypnotics to induce relaxation and analgesia while keeping the patient awake, conscious, with autonomous breathing and intact protective reflexes. The patient experiences the procedure without anxiety or pain but without completely losing consciousness.
Conscious sedation (or aware sedation) is a pharmacological technique that uses anxiolytics, hypnotics or opioids to induce a state of relaxation, anxiety reduction and analgesia, keeping the patient awake and cooperative.
The patient is conscious, breathes autonomously, maintains the protective reflexes of the airways and is able to respond to simple verbal commands. Conscious sedation is not deep sleep: the patient experiences the procedure without anxiety and without pain, but without completely losing consciousness.
How it works
Conscious sedation can be administered orally with benzodiazepines 30-60 minutes before the procedure, simple but less controllable, or intravenously with midazolam or propofol through a cannula, with immediate effect and dosage titratable in real time, ideal for moderate-severe anxiety and complex procedures.
Conscious sedation can be administered in two ways:
Oral sedation
- Administration of an anxiolytic drug (typically a benzodiazepine: diazepam, lorazepam, midazolam) about 30-60 minutes before the procedure
- Simplicity of execution (no additional staff needed)
- Less controllable: once taken, the drug follows its metabolic course
- Suitable for mild-moderate anxiety and short procedures
Intravenous sedation (I.V.)
- Controlled administration of drugs (midazolam, propofol, remifentanil) through a cannula in a vein
- Immediate effect and dosage titratable in real time by the anaesthesiologist or the surgeon with specific training
- Greater control: the sedation can be deepened or lightened based on the patient's response
- Suitable for moderate-severe anxiety and complex, prolonged procedures
Advantages
The advantages of conscious sedation include absence of anxiety during the procedure, complete analgesia in combination with local anaesthesia, reduction of the gag reflex particularly useful for the upper maxilla, cooperation of the calm and immobile patient, retrograde amnesia that makes the procedure forgotten and rapid recovery in a few hours.
- No anxiety: the patient faces the procedure in complete relaxation, without perceiving the duration of time
- No pain: the sedation is combined with local anaesthesia, completely eliminating the painful sensation
- Reduction of the gag reflex: particularly useful for procedures on the upper maxilla
- Patient cooperation: the patient is calm, does not move suddenly and does not interfere with the procedure
- Retrograde amnesia: many patients do not remember the procedure or have a vague and comfortable memory of it
- Rapid recovery: the patient can go home after a few hours (if accompanied)
Difference with general anaesthesia
Unlike general anaesthesia, conscious sedation maintains consciousness, autonomous breathing and protective reflexes. It requires only a surgeon and a nurse instead of the complete anaesthesiological team, recovery is 1-2 hours versus 4-8 hours, does not require hospitalisation and has a lower cost.
| Characteristic | Conscious sedation | General anaesthesia |
|---|---|---|
| Consciousness | Maintained | Lost |
| Breathing | Autonomous | Assisted/controlled |
| Reflexes | Present | Absent |
| Required staff | Surgeon + nurse | Anaesthesiologist + nurse + surgeon |
| Monitoring | Pulse oximetry, BP, ECG | Complete invasive monitoring |
| Recovery | 1-2 hours | 4-8 hours |
| Hospitalisation | Not necessary (day surgery) | Often necessary |
| Cost | Lower | Higher |
Use in BSS
The Bilateral Sinus Solution™ (BSS) is performed by the Nicola Lettera Team under conscious sedation as standard. The 4-6 hour procedure per arch is experienced in complete relaxation. The sedation is ideal because it requires cooperation in the delicate phases, the patient must remain immobile during the passage through the tuber and sphenoid and the rapid recovery allows immediate loading in 24-48 hours.
The Bilateral Sinus Solution™ (BSS) is performed by the Nicola Lettera Maxillofacial Team under conscious sedation as standard. The procedure, which lasts about 4-6 hours for a complete arch, is experienced by the patient in a state of complete relaxation.
Conscious sedation is particularly suitable for BSS for several reasons:
- The procedure is complex and requires the full cooperation of the patient, who however must not feel anxiety or discomfort
- The surgical technique includes delicate phases (passage through the tuber and the sphenoid) in which the patient must remain immobile
- Immediate loading (delivery of the prosthesis in 24-48 hours) requires a rapid awakening without residual effects
- Most patients treated with BSS have already had previous traumatic experiences (implant failures, removable dentures) and have a high level of anxiety
