Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

972
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.

Inhalational 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...

Stages of General Anesthesia

2.5K
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...

General 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...

Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

2.2K
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives 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...

Summary

Sevoflurane sedation for geriatric colonoscopy is a safe and effective alternative to propofol. This study found fewer complications like apnea and general anesthesia with sevoflurane.

Area of Science:

  • Anesthesiology
  • Gastroenterology
  • Geriatric Medicine

Background:

  • Colonoscopy is a common procedure in geriatric patients.
  • Sedation is crucial for patient comfort and procedural success.
  • Propofol is a widely used sedative, but safety concerns exist in the elderly.

Purpose of the Study:

  • To compare the safety and efficacy of sevoflurane-based sedation versus propofol for colonoscopy in geriatric patients.
  • To evaluate complication rates, anesthetic requirements, and procedural timing.

Main Methods:

  • A prospective, controlled study involving 60 elderly patients undergoing colonoscopy.
  • Random allocation into two groups: propofol (P group) and sevoflurane (S group).
  • Monitoring of complications (apnea, airway intervention, general anesthesia, hemodynamic instability), fentanyl use, and procedure/recovery/discharge times.

Main Results:

  • The propofol group experienced significantly more apnea, airway interventions, and general anesthesia compared to the sevoflurane group.
  • No significant differences were observed between groups for other measured variables.
  • Both sedation techniques were generally well-tolerated.

Conclusions:

  • Sevoflurane provides a safe and effective sedation option for colonoscopy in geriatric patients.
  • Sevoflurane may be associated with a lower risk of respiratory complications and general anesthesia conversion compared to propofol.
  • Further research can explore optimal sevoflurane dosing and its long-term safety profile in this population.
