According to the American Society of Anesthesiologists, many factors determine the level of anesthesia or sedation required for a biopsy, primarily the procedure's invasiveness and the patient's overall health. The most appropriate option is carefully selected based on these factors to ensure patient comfort and safety, addressing what kind of sedation is used for biopsy.

The incidence of fetal bradycardia, a drop in the fetal heart rate, is approximately 15% following a paracervical block, making it the procedure's most significant side effect [1.3.2]. So, what is the most common adverse effect of a paracervical block? It is this transient change in heart rate [1.2.3].

For most patients, dental numbness from local anesthesia lasts between two and three hours. However, the duration of numbness depends on several factors, including the type of anesthetic used, the injection site, and individual metabolism, all of which determine how long until anesthesia numbness goes away.

Millions of people suffer from localized pain, and for many, a combination of anti-inflammatory and nerve-numbing therapies can provide more comprehensive relief. Understanding if and how you can safely use diclofenac and lidocaine together is crucial for effective pain management, which may involve prescription compounded products or careful sequential application.

Lidocaine works by blocking the influx of sodium ions into nerve endings, effectively preventing pain impulses from traveling to the brain. However, the answer to the question, "Can you still feel pain with lidocaine?" is not a simple 'no'; it's possible to feel other sensations or, in certain circumstances, still perceive some level of pain.

While millions use lidocaine patches for localized pain, a common question arises: are lidocaine patches an anti-inflammatory? Primarily, they are local anesthetics that block pain signals, though research shows lidocaine does possess some anti-inflammatory properties [1.3.6, 1.2.3, 1.2.1].

Local anesthetics are used extensively, with recent studies showing a systemic toxicity (LAST) rate of about 1-2 events per 1,000 peripheral nerve blocks [1.11.1]. So, does lidocaine stop pain before it happens? Yes, by blocking pain signals at the nerve level, it can prevent the sensation of pain from ever reaching the brain [1.2.1, 1.2.2].

While nearly 99% of patients undergoing total knee arthroplasty at specialized centers like HSS receive a nerve block, the national average is only about 1 in 4 [1.7.4]. So, how long does it take for a nerve block to get out of your system after a procedure?

Most nerve blocks for ankle surgery provide pain relief for 12 to 24 hours, though some can last up to 36 hours. The duration of a nerve block depends on the anesthetic used and the specific type of block administered to the ankle region.

According to studies, patients using an On-Q pain pump after surgery can experience significantly lower pain scores and higher satisfaction compared to those using traditional pain medication alone. To benefit fully from this technology, it is crucial to know how to verify its proper function, a common concern that prompts the question, 'how do I know if my on-q pain pump is working?'
