No Control Group
Topical lidocaine and bupivacaine alone

This trial requires 40 total participants across 4 different treatment groups

This trial involves 4 different treatments. Aminocaproic Acid is the primary treatment being studied. Participants will be divided into 4 treatment groups. There is no placebo group. The treatments being tested are in Phase 4 and have been shown to be safe and effective in humans.

Topical lidocaine and bupivacaine aloneIn this treatment group, each solution will include 5 ml of 1% lidocaine, 5 ml of 0.25% bupivacaine
Topical lidocaine and bupivacaine with thrombinIn this treatment group, each solution will include 5 ml of 1% lidocaine, 5 ml of 0.25% bupivacaine, 10000 units of thrombin
Topical lidocaine and bupivacaine with thrombin and tranexamic acidIn this treatment group, each solution will include 5 ml of 1% lidocaine, 5 ml of 0.25% bupivacaine, 10000 units of thrombin, and 500 mg of tranexamic acid

What are common treatments for opioid pain medication?

Add answer

Most often, treatments for opioid pain relief are not prescribed by the healthcare provider or the patient, although it's possible that they take place at their home. Some patients may be prescribed opioids at home.\n

Unverified Answer

What is opioid pain medication?

Add answer

It is important that all physicians and patients adequately understand what opioid medications are to be used for which conditions and what safety precautions are necessary when opioid medications are being prescribed to patients.

Unverified Answer

How many people get opioid pain medication a year in the United States?

Add answer

About 18% of American Americans take pain medication every day, and over 14% take opioid pain medication every day. While only 5% of US adults have had a period of non-medical opioid use, about 7% of US adults have had one or more major opioid prescription drug interactions, with a quarter of those taking opioids. Only 10% of opioid prescribed patients received information regarding drug interactions. Therefore, over 90% of prescription opioid use in real-world practice may be associated with potentially lethal opioid drug interactions.

Unverified Answer

Can opioid pain medication be cured?

Add answer

Pain is common/endorphine use is common. A very large proportion of users experience a long-lasting reduction of opioid use and a cure. Clinically relevant benefits of opioid medication are rare and more likely to be side effects and addiction than good, perhaps life-long, reductions in pain. Results from a recent paper supports the use of a cure-focused approach to pain management.

Unverified Answer

What are the signs of opioid pain medication?

Add answer

Many different signs are associated with opioids. Most of the signs are vague, while others are more specific. Common symptoms include dizziness or lightheadedness, shortness of breath, and constipation or nausea/vomiting. An increased heart rate, sweating, drowsiness and decreased alertness may be observed. There may also be increased pain when the subject experiences pain with or without opioid use. Severe withdrawal is associated with a severe flu-like reaction. Alcohol use is often combined with opioid use, making signs of alcohol use in combination with opioid use more subtle. Opioid-related signs and symptoms are often overlooked or mistaken for other conditions.

Unverified Answer

What causes opioid pain medication?

Add answer

It appears that factors such as family history, sex and genetics, health and social factors, and psychosocial stress may contribute to which individuals use opioid medications. Despite this complex relationships the use of opioids to treat pain in the elderly is still a major issue.

Unverified Answer

How does aminocaproic acid work?

Add answer

Aminocaproic acid seems to induce an antiinflammatory response, thereby lowering blood-proteins levels and relieving pain. However, due to the low number of randomized double-blind studies with appropriate design, little can be said about the absolute indications, effects, and side-effects of this drug compared with other analgesics. The authors' opinion is that the absolute data need to be pooled from random double-blind trials and compared with placebo for further evaluation.

Unverified Answer

Is aminocaproic acid typically used in combination with any other treatments?

Add answer

ACP is prescribed as a first-line treatment for a broad spectrum of dermatologic conditions, and is usually combined with an antipruritic. Although this study identified several small trials showing the safety and effectiveness of ACP with standard analgesic treatment, as of February 2013, no placebo-controlled trials that studied the combination of ACP and a standard analgesic had been published, and we could not identify any clinical trials specifically investigating the use of ACP with analgesics for treatment of HNP. In a recent study, findings could have been different had ACP been used alone. The study was largely based on individual patient cases and small trial designs, some used to investigate the mechanism of action of ACP alone.

Unverified Answer

What is the primary cause of opioid pain medication?

Add answer

Recent findings found that many patients had been prescribed opioids for reasons other than their primary complaint of pain. This finding would suggest that there is a group of patients who are misdiagnosed as having a primary complaint of pain and receive treatment with opioids based on that misdiagnosis. The use of a pain specialist as part of a comprehensive medical panel should assist physicians in assessing and managing the patients' pain.

Unverified Answer

Does opioid pain medication run in families?

Add answer

Significant heritability was noted for pain scores, tolerance to morphine, physical dependence and opioid-induced hyperalgesia (OIHA). Data from a recent study also suggest that the heritability of OIHA is largely unrelated to that of baseline pain scores and morphine tolerance and that OIHA may be a functional somatic symptom, possibly due to dysregulation of brain endorphin systems.

Unverified Answer

Is aminocaproic acid safe for people?

Add answer

ACPA is an antidote for most agents (except for sodium fluoroacetate, a medication of veterinary origin). However, the dose-toxicity information available is too poor to allow safe use as an antidote. The only reliable data show that intravenous injection of ACPA is not teratogenic, that is, it does not cause birth defects.

Unverified Answer

What does aminocaproic acid usually treat?

Add answer

Aminocaproic acid is used in a number of conditions, and it's safety profile has been well studied. It has been shown to decrease pain in many chronic conditions and also for acute pain. It is sometimes used in patients who have a high dose of pain medication in their treatment plan (such as opioids), as a short-term add on therapy. Aminocaproic acid is also used during dental procedures to control bleeding from nerves. There are a number of reports of patients having adverse responses to aminocaproic acid resulting in the death of the patient including two of the authors (a dentist and a dentist assistant).
