Q. When lidocaine is given as a heart medication, does the entire chest go numb?
Doctor Answer is medically reviewed by SecondMedic medical review team.
No, lidocaine is not a strong enough anesthetic to cause complete numbness in the chest. However, it can be used to provide localized relief from pain in certain areas of the chest. Studies have shown that lidocaine can reduce myocardial infarction-related ischemic pain, as well as angina-related chest pain caused by increased oxygen demand on cardiac muscle due to physical activity or emotion. Localized use of lidocaine for cardiac causes has been found to work because its effects are limited in scope and duration without significant systemic absorption (as compared with other medication such as opioid analgesics). The drug inhibits sodium influx into nerve cells, thereby reducing conduction frequencies and amplitudes throughout myocardium, resulting in decreased excitability and diminished sensory impulses leading to a reduction of anginal episodes. Not only does this have clinical benefits for people suffering from heart conditions; it also offers unique insight into how drugs help treat different forms of cardiovascular disease.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
