Nasal irrigation with salt water is recommended by 87% of family doctors as an adjunctive treatment to relieve the symptoms of nasal congestion and sinusitis. The simplest method is to hold salt water in your cupped hand, block one nostril while you inhale the water into the other nostril, then blow your nose. The high-tech version is to use a Neti pot, a little jug with a spout. You pour the salt solution from the Neti pot into one nostril and it drains out the other nostril. The technique is described here.
The Neti pot originated in India in Ayurvedic medicine. Neti is Sanskrit for “nasal cleansing.” Other related ancient techniques that have not been adopted by scientific medicine include using a string instead of water and a yoga technique where you close one nostril, pour the solution into the other nostril and allow it to run out of the mouth.
Nasal irrigation provides short-term symptomatic relief and may improve nasal mucociliary clearance. It removes mucus not only from the nose but also from the maxillary and ethmoid sinuses. (more…)
You’re a patient. That cold just isn’t getting better and you have purulent drainage from your nose, and your face hurts and your teeth hurt. You probably have sinusitis, right? You go to a doctor to get an antibiotic.
You’re a doctor. Deep down, you know there’s a good chance the patient has a self-resolving condition. You’d rather not do x-rays on every patient who presents with these symptoms, because x-rays are expensive, expose the patient to harmful radiation, and they are not always accurate. You could puncture the sinuses and take a sample for bacteriological culture, but that’s expensive, painful, and the patient would NOT appreciate it. The patient may not really need treatment, but you want very much to do something to help. If you can find a reason to give the patient an antibiotic, you can feel that you have done something worthwhile. Antibiotics don’t work for a viral infection, but you rationalize that you’re not 100% sure it’s not bacterial, and that sometimes a bacterial infection develops superimposed on a viral infection and mild bacterial infections can develop into severe ones with complications, and maybe you could ward that off. You convince yourself that it really would be prudent to prescribe an antibiotic. Both you and your patient are happy. The patient gets better. You remember this pleasant experience and are reinforced to do the same next time.
Maybe that’s not such a good idea.
A recent study in JAMA showed that antibiotics were not superior to placebo for treating bacterial sinusitis diagnosed by the clinical criteria used by many primary care physicians. There is a growing concern that we have been overtreating sinus infections. Recent research has also shown that we were overtreating ear infections in children, that many of them resolve just as fast without treatment. That doesn’t mean antibiotics should never be used for ear infections. There are now guidelines for using age and clinical presentation to determine which children to treat and which ones can be safely observed without antibiotics. Most of these observed ear infections will resolve but some will eventually require antibiotics too. The situation with sinusitis is similar: most patients may not need antibiotics, and we’re trying to thrash out better criteria for identifying those who will.
Critics point to this kind of thing as a defect of conventional medicine. We use treatments that are not based on good evidence. We do things for years and then find out we were wrong. New studies are constantly contradicting older studies. We keep changing our minds. (more…)
