Summary
Injectable hydrogels show promise for extending local anesthetic action, offering a potential solution for prolonged pain control. This approach aims to improve pain management with reduced toxicity.
Area of Science:
- Biomedical Engineering
- Drug Delivery Systems
- Anesthesiology
Background:
- Effective pain management, especially post-operative, remains a significant clinical challenge.
- Local anesthetics are crucial for acute and chronic pain but often have short durations of action.
- Current methods to prolong local anesthetic effects have limitations in duration and toxicity.
Purpose of the Study:
- To explore the potential of injectable hydrogels for prolonged local anesthetic delivery.
- To discuss hydrogels as a viable drug delivery system for extended neural blockade.
Main Methods:
- Review of existing literature on drug delivery systems for local anesthetics.
- Focus on injectable, responsive hydrogels for localized anesthetic administration.
- Discussion of hydrogel properties relevant to sustained drug release and neural targeting.
Main Results:
- Injectable hydrogels offer a promising platform for localized, sustained release of anesthetic agents.
- Hydrogels can be engineered to provide tunable release profiles for extended durations.
- This approach has the potential to achieve neural blockade for hours to days.
Conclusions:
- Injectable hydrogels represent a significant advancement in local anesthetic drug delivery.
- They offer a potential strategy to overcome the limitations of current pain management techniques.
- Further research into hydrogel-based systems could lead to improved patient outcomes for pain control.

01:23Local Anesthetics: Common Agents and Their Applications
1.3K
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:25Analgesia and Pain Management
3.2K
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...

7.3K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
1.0K
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...

2.7K
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...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
