Is The Damage To The Lungs In Bronchopulmonary Dysplasia Permanent
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
No: Meconium aspiration, per se, is uncommon, and many cases of so-called meconium aspiration are simply other forms of respiratory distress noted in newborns who also passed meconium prior to delivery. True meconium aspiration does cause acute lung injury but most, if not all, cases heal completely within days to weeks. ...Read moreSee 1 more doctor answer
In glaucoma, please define what minimal damage to the optic nerve is. A certain percentage of damage?
Detectable: The best research indicates that the optic nerve (as studied by scanning of its structure and observation of it surface architecture) will have some change indicating damage well before there is any functional problem. In this context then, minimal damage is observable change, prior to the onset of visual or functional measured change. ...Read more
What duration of full body Anesthesia will cause damage to the brain? Will that decrease your IQ? Is the brain unrecoverable from the damage?
Odd question: Where did you get the idea that anesthesia causes brain damage? Anesthesia is a controlled sequence of dropping sensation but while preserving/supporting body functions like breathing, oxygen exchange, fluid balance. These do not damage if done properly. If your question is really about coma, the involuntary loss of consciousness,outcome is determined by the cause of the coma. ...Read more
Can lung scar(granulomas) can removed in the lungs?Is there other option to lessen the scar in the lungs? Medications?Operation?
Varies: If you have acute inflammation causing spinal cord symptoms, this represents a relapse, which can be controlled and reversed by steroids, ACTH, or plasmapheresis. If this is old and chronic, currently, we lack good therapeutic success, but stem cells are potentially an answer, and some therapies to restore myelin are on horizon. Best approach remains prevention: Tysabri, (natalizumab) Gilenya, or Lemtrada ...Read more

Surfactant: I believe that you are referring to something called the surfactant layer. Surfactant is composed of lipoproteins. Alveoli are the tiny structures shaped like bubbles which are the location of oxygen exchange in the lungs. Without them, we cannot oxygenate our blood. A layer of this surfactant is critical in keeping these tiny "bubbles" from collapsing in on themselves. ...Read more

Aerobic, arm/depends: There are 2 separate questions here, both great! exercise is recommended for lung patients, with an emphasis on aerobic conditioning but also upper body weight training--which helps when short of breath. For fibrosis, chances of "removal" or cure depends on the cause. If no cause is known, less chance for resolution. See a pulmonologist (lung specialist) for evaluation. ...Read more
How to handle/treat eustachian tube dysfunction? In the worst case, does surgery necessary?Could it gives permanent damage in ear/nerve/etc?
Relieve or bypass: The eustachian tube is the connector between the back of the nose and the middle ear. It's function is to allow pressure to equilibrate in the middle ear. Acutely it can be block by uris or acute allergic nasal congestion. Chronically enlarged adenoids and allergic or non-allergic nasal congestion is most common. Consider treating those. Other option is tympanostomy tube(s) to bypass eustachian t. ...Read moreSee 1 more doctor answer
If the genitofemoral nerve is suspected to be damaged, then can the presence of cremasteric reflex b used to sense that injury is not severe in nature?
Complex: I think there are too many possibilities to give a good answer. I can say that if that works it is a good thing and if it wasn't working and is returning to function that is also a very good thing. ...Read more
Bronchopulmonary dysplasia is a form of chronic lung disease that affects newborns (mostly premature) and infants. It results from damage to the lungs caused by mechanical ventilation and long-term use of oxygen for more than 28 days. Most infants recover from BPD, but some may ...Read more
