Summary
Dexmedetomidine, a selective alpha(2)-adrenoreceptor agonist, provides sedation, analgesia, and hemodynamic stability without respiratory depression. This review highlights its efficacy and safety across various surgical and procedural settings, reducing the need for other sedatives.
Area of Science:
- Anesthesiology and Pharmacology
Background:
- Dexmedetomidine is a selective alpha(2)-adrenoreceptor agonist used for sedation and analgesia in intensive care units (ICU).
- It offers unique properties like sedation, anxiolysis, analgesia, and minimal respiratory depression, alongside sympatholytic and antinociceptive effects for hemodynamic stability.
Purpose of the Study:
- This review focuses on the perioperative applications of dexmedetomidine.
- It examines its utilization in premedication, general, neuro, cardiac, and bariatric surgery, as well as procedural sedation and awake fiberoptic intubation.
Main Methods:
- The review synthesizes findings from various studies on dexmedetomidine's efficacy and safety.
- It analyzes its role as an adjuvant to other anesthetic and sedative medications.
Main Results:
- Dexmedetomidine consistently reduces the requirement for opioids, propofol, and benzodiazepines.
- It has demonstrated efficacy and safety in diverse anesthetic management scenarios.
- Common side effects include bradycardia and hypotension.
Conclusions:
- Dexmedetomidine is an effective and safe adjuvant in a wide range of anesthetic management.
- Its unique pharmacological profile offers significant benefits in perioperative care.
- Further research supports its expanding role in surgical and procedural sedation.

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.
01:24General Anesthesia: Overview
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

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...
01:20Inhalational 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...
01:31Skeletal 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...
