定期灌洗鼻腔(洗鼻),減少95% COVID-19感染住院?!

【30秒重點】

  • 想洗鼻子的人可以用生理食鹽水洗鼻器;要加優碘或小蘇打,先問醫師或藥師。
  • 美國一項79名新冠門診病人的小型觀察研究:確診24小時內開始洗鼻,住院風險降低約95%。
  • 加優碘的組別恢復比較快。
  • 作者自己疫情期間每天用240毫升洗鼻,但沒有加優碘或小蘇打。

今天讀到的報告。值得試試!

從疫情以來,我定期(通常每天一次)沖洗鼻子(Neilmed Sinus Rinse; 240mL),尤其有外出購物之後。但我從沒額外添加以下試驗所提到的優碘(povidone-iodine)或碳酸氫鈉(小蘇打粉)。

以下試驗顯示加入2.5ml「優碘」似乎效果很好。


研究摘要:

Abstract

Objective: To determine whether nasal irrigation initiated within 24 hours of a positive PCR test result reduces hospitalizations for COVID-19. Design, Setting and Participants: Prospective case:cohort trial comparing clinical outcomes in patients aged 55 years or older who were PCR positive at a community testing site in Augusta, Georgia. Patients randomized to initiate one of two nasal irrigation regimens within 24 hours of testing were compared to outcomes in the CDC national database for the same time period. Interventions: Participants were assigned on alternate days to one of two pressure-based nasal irrigation systems (NAVAGE, Rhinosystems Inc.) or Neilmed Sinus Rinse (Neilmed Inc.), and randomized to include 2.5ml povidone-iodine or 0.5 teaspoon sodium bicarbonate to the standard saline rinse twice daily for 14 days with 14-day follow-up. Main Outcomes and Measures: The primary outcome was hospitalization for COVID-19 symptoms within 28 days of enrollment by daily self-report confirmed with phone follow-up and hospital records compared to hospitalization rates publicly available from the CDC. Secondary outcomes in enrolled patients compared symptom resolution and home exposure, adherence to nasal irrigation, and any impact of irrigation system or antiviral or alkalization addition to the irrigant. Of 79 patients assigned to nasal irrigation (63.99[7.96] years, 36[45.6%] female, 43[54.4%]male), 0/37 assigned to povidone-iodine and 1/42 patients in the alkalinization group had a COVID-19 related hospitalization (1.26%). From September 22 to December 21, 2020, in patients 50+ years the CDC reported 1022977 cases with 197777 hospitalizations, or 19.33% (OR:0.054, 95%CI0.0074 to 0.38, p=0.0036). Full daily diaries were completed by 62 patients, averaging 1.79 irrigations/day. There were no statistical differences in symptomatic outcomes by irrigation unit used, but symptom resolution in 14 days was more likely in the povidone-iodine group (21/27) than the alkalinization group (17/35, p=0.019). Conclusion: Patients who initiated mechanical isotonic saline nasal debridement within 24 hours of a positive COVID-19 PCR test were 19 times less likely to be hospitalized than the national rate. Further research is required to determine if adding betadine to irrigation reduces morbidity and mortality of SARS-CoV-2 infection.
