Summary
Intranasal dexmedetomidine effectively sedated patients undergoing third molar extraction. This method proved safe and convenient, offering a viable alternative for dental sedation.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Sedation is crucial for managing patient anxiety and comfort during dental procedures.
- Mandibular third molar removal often requires effective sedation techniques.
Purpose of the Study:
- To assess the efficacy and safety of intranasal atomized dexmedetomidine for sedation during mandibular third molar extraction.
Main Methods:
- A randomized, crossover study involving 18 patients undergoing third molar removal.
- Patients received either intranasal dexmedetomidine (1.5 μg/kg) or placebo (water) in two sessions.
- Sedation levels were monitored using the Observer's Assessment of Alertness/Sedation (OAA/S) scale and bispectral index (BIS).
Main Results:
- Intranasal dexmedetomidine significantly improved sedation compared to placebo starting at 20-30 minutes post-administration.
- Peak sedation effects were observed between 40-50 minutes.
- Minor decreases in heart rate and blood pressure were noted, remaining within safe limits (<20% of baseline).
Conclusions:
- Intranasal atomized dexmedetomidine is an effective, safe, and convenient sedative for mandibular third molar extraction.
- This administration route offers a promising alternative for procedural sedation in dentistry.

01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
01:31Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
01:20Inhalational Anesthetics: Overview
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:22Stages of General Anesthesia
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
01:19Depolarizing Blockers: Pharmocokinetics
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
