Summary
Local anesthetic use, whether topical or infiltrated, significantly reduces pain after tonsillectomy. This meta-analysis confirms its effectiveness for managing post-tonsillectomy pain, with no significant adverse effects reported.
Area of Science:
- Anesthesiology
- Otolaryngology
- Pain Management
Background:
- Effective management of post-tonsillectomy pain is crucial for patient recovery.
- Previous meta-analyses indicated local anesthetics reduce postoperative pain.
- Current evidence needed to be reviewed and compared to prior findings.
Purpose of the Study:
- To systematically review current evidence on local anesthetic use for post-tonsillectomy pain.
- To compare current findings with a 2008 meta-analysis.
- To assess the efficacy and safety of local anesthetics in reducing post-tonsillectomy pain.
Main Methods:
- Systematic literature searches were conducted in MEDLINE, EMBASE, and PubMed.
- A meta-analysis of randomized control trials was performed.
- Studies assessed the use of local anesthetic agents for post-tonsillectomy pain.
Main Results:
- Twenty-three studies were included in the meta-analysis.
- Local anesthetic (topical or infiltrated) significantly reduced pain scores compared to controls.
- Pain reduction was significant at 4-6 hours, 24 hours, and 5-7 days post-surgery.
Conclusions:
- Peri-operative local anesthetic use improves post-tonsillectomy pain outcomes.
- Studies were generally small, suggesting a need for larger multi-centered trials.
- No significant adverse side effects were reported with local anesthetic use.

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
633
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...

01:13Local Anesthetics: Pharmacokinetics
1.1K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

1.2K
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...

01:30Local Anesthetics: Chemistry and Structure-Activity Relationship
6.2K
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...

01:12Local Anesthetics: Adverse Effects
696
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1000
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
