Q. How does general anaesthesia affect the body and brain during surgery?
Doctor Answer is medically reviewed by SecondMedic medical review team.
General anaesthesia is a medically induced state of unconsciousness that ensures patients do not feel pain or remember the surgical procedure. It works by affecting both the brain and body, altering normal physiological functions temporarily. Here’s how it impacts different systems:
1. Effects on the Brain
-
Loss of Consciousness – General anaesthesia suppresses brain activity, preventing awareness, movement, or response to pain.
-
Memory Suppression – The drugs interfere with the brain's ability to form memories, ensuring patients do not recall the procedure.
-
Slowed Brain Function – Neural communication is significantly reduced, leading to a deep sleep-like state. Some patients may experience temporary confusion or grogginess upon waking up.
2. Effects on the Cardiovascular System
-
Lowered Blood Pressure – Anaesthetic agents cause blood vessels to relax, leading to a drop in blood pressure. This is closely monitored during surgery.
-
Altered Heart Rate – Some anaesthetics may slow down or, in rare cases, increase heart rate, requiring careful regulation by anaesthesiologists.
3. Effects on the Respiratory System
-
Temporary Breathing Suppression – Since anaesthesia can slow or stop breathing, a breathing tube is often placed to maintain oxygen flow.
-
Reduced Airway Reflexes – Protective reflexes like coughing and swallowing are temporarily inhibited, making it essential for medical professionals to manage airway support.
4. Effects on the Muscular and Nervous System
-
Muscle Relaxation – Many anaesthetic drugs induce muscle relaxation, which is crucial for certain surgeries but requires controlled breathing support.
-
Suppressed Pain Signals – The nervous system’s ability to transmit pain signals is temporarily blocked, ensuring a painless surgical experience.
5. Effects on the Digestive System
-
Delayed Stomach Emptying – General anaesthesia slows down digestion, which is why fasting before surgery is crucial to prevent aspiration (inhaling stomach contents into the lungs).
-
Post-Surgery Nausea and Vomiting – Some patients experience nausea after waking up, often managed with medications.
Post-Anaesthesia Recovery
After the surgery, patients are gradually awakened as anaesthetic drugs wear off. The recovery process may involve:
-
Drowsiness and confusion for a few hours
-
Mild nausea or dry mouth
-
Temporary memory gaps or grogginess
Conclusion
General anaesthesia is a highly controlled medical procedure designed to ensure patient comfort and safety during surgery. While it affects multiple body systems, medical professionals continuously monitor and adjust anaesthetic levels to minimize risks. If you have concerns about anaesthesia before a procedure, consult your healthcare provider for personalized guidance.
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.
