Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

565
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.

Local Anesthetics: Clinical Application as Epidural Anesthesia

677
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 Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

897
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...

Analgesia and Pain Management01:25

Analgesia and Pain Management

1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

General Anesthesia: Overview01:24

General Anesthesia: Overview

556
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...

Summary

Intra-operative corticosteroids significantly reduced postoperative pain after third molar surgery, especially when combined with nonopioid analgesics. Dexamethasone improved pain control in both opioid and nonopioid groups, suggesting its incorporation into pain management strategies.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Anesthesiology
  • Pharmacology

Background:

  • Corticosteroids are known to reduce postoperative swelling and trismus.
  • The efficacy of corticosteroids in pain management, particularly in conjunction with different analgesic types (opioid vs. nonopioid), requires further investigation.

Purpose of the Study:

  • To evaluate the impact of intra-operative corticosteroids on postoperative pain following third molar surgery.
  • To compare the pain-reducing effects of corticosteroids when used with nonopioid analgesics (NSAIDs, acetaminophen) versus opioid analgesics.

Main Methods:

  • Retrospective cohort study of 1,774 patients undergoing third molar surgery.
  • Primary predictor variables included analgesic treatment (opioid or nonopioid) and intra-operative steroid use.
  • Pain levels were assessed using a numeric rating scale on postoperative days 1, 2, and 3, with statistical analysis using mixed-effects models.

Main Results:

  • Intra-operative steroid use was associated with significantly lower pain scores on postoperative day 1 in both nonopioid and opioid groups.
  • The nonopioid analgesic group combined with intra-operative steroids demonstrated the lowest overall pain scores across all measured days.
  • Steroid administration improved pain control regardless of the analgesic regimen used.

Conclusions:

  • Intra-operative intravenous dexamethasone effectively reduces acute postoperative pain after third molar surgery.
  • Dexamethasone enhances pain management when administered with either nonopioid or opioid analgesics.
  • The findings support the integration of intra-operative IV dexamethasone with standard postoperative nonsteroidal anti-inflammatory drugs and acetaminophen for improved pain control.
