Summary
Target-controlled anesthesia delivery systems significantly reduce anesthetic gas consumption, lowering costs and environmental pollution compared to manual control. This efficiency makes end-tidal control a valuable method for modern anesthesia.
Area of Science:
- Anesthesiology
- Pharmacokinetics
- Environmental Health
Background:
- General anesthesia poses significant cost and environmental pollution challenges.
- Target-controlled (TC) anesthesia delivery, also known as end-tidal (ET) control, is proposed as a solution.
Purpose of the Study:
- To evaluate the efficacy and safety of TC anesthesia delivery systems.
- To determine if TC systems reduce anesthetic agent consumption, cost, and environmental impact compared to manual control.
Main Methods:
- A randomized study of 200 patients undergoing laparoscopic surgery, divided into TC and manual-controlled (MC) groups.
- Comparison of gas consumption, time to achieve target sevoflurane levels, maximum inspired concentration, and number of adjustments.
Main Results:
- TC group showed significantly lower nitrous oxide and sevoflurane consumption (P < 0.05).
- TC systems required fewer adjustments and achieved target anesthetic levels faster.
- Reduced consumption in the TC group led to an approximate cost saving of $1.12 per hour and decreased environmental pollution.
Conclusions:
- End-tidal (ET) control is an efficient anesthesia delivery system.
- TC anesthesia conserves anesthetic gases, leading to significant reductions in both cost and environmental pollution.

1.7K
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...

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...

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.

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

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...

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
