Insights

Remifentanil, a potent opioid, offers rapid metabolism and predictable effects, unaffected by organ dysfunction. Its unique profile necessitates changes in postoperative pain management strategies for enhanced patient safety.

Area of Science:

  • Anesthesiology and Pharmacology

Background:

  • Remifentanil is a potent mu-opioid agonist with rapid metabolism by tissue esterases.
  • This unique pharmacokinetic profile is independent of renal or hepatic function.

Purpose of the Study:

  • To evaluate the implications of remifentanil's pharmacokinetic profile on its use in general anesthesia and cardiac surgery.
  • To discuss modifications needed for postoperative pain control and sedation.

Main Methods:

  • Pharmacokinetic analysis of remifentanil metabolism.
  • Review of clinical applications in general anesthesia and cardiac surgery.
  • Assessment of impact on emergence times and postoperative pain management.

Main Results:

  • Remifentanil pharmacokinetics are unaffected by severe renal or hepatic dysfunction.
  • Dosage adjustments are not required during general anesthesia, with no undue lengthening of emergence times.
  • Rapid offset of action requires revised approaches to early postoperative pain control.

Conclusions:

  • Remifentanil can be used safely in various surgical settings, including cardiac surgery, due to predictable pharmacokinetics.
  • Its use as a sedative or postoperative analgesic requires careful administration, avoiding bolus doses.
  • Implementation of remifentanil necessitates significant changes in prescribing habits to maximize patient safety and optimize outcomes.

Skeletal 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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
Parenteral Anesthetics: Overview01:24

Parenteral 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.
Inhalational Anesthetics: Overview01:20

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...
Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
