1. 中醫如何診斷「長新冠」後遺症?哪方面對新冠肺炎康復者的影響最大?

第五波新冠肺炎疫情下本地確診宗數已累積過百萬宗,有患者康復後出現「新冠肺炎長期綜合後遺症 (Post COVID-19 condition)」(簡稱「長新冠 (Long COVID)」症狀。世界衛生組織(WHO)去年10月公佈臨床定義:「這種症狀通常發生在確診者或曾被新冠病毒感染的人士身上,通常在染疫後3個月內出現,徵狀持續至少2個月,並且無法由其他診斷解釋由來」。就臨床所見,感染2019冠狀病毒病檢測轉陰性後,康復期間常見病徵包括呼吸道症狀如下:持續或反覆咳嗽、痰黏、咽乾丶咽痛丶咽癢,或有胃腸道症狀如腹脹、胃口差,大便溏或易腹瀉;又患者或出現如下精神症狀:常感焦慮、緊張、心慌、心悸、睡眠差、難以入睡、半夜易醒、精神差、集中力差、記性差;部分患者還可以出現嗅覺或味覺減退、氣短、眩暈、頭痛、肌肉痛、皮膚出疹、盜汗、自汗、視力模糊、眼睛瘙癢;育齡女性可出現月經失調。

大部分長新冠患者均感疲倦、體能轉差、思維變慢,導致工作效率下降。利用中醫藥進行調理,可改善相關症狀之餘,更能改善體質,從而促進復元。

 

2. 針對「長新冠」,中醫建議新冠肺炎康復者應如何調理身體?請舉出日常生活需要注意的地方?

一旦感染2019冠狀病毒病,無論在發病期間或檢測已轉為陰性而處於康復期,尤須注意飲食,保持居所空氣流通,多休息。《內經》說:「正氣存內,邪不可干」,意思就是只要身體正氣充足,邪氣就不容易侵犯,同時強調:「虛邪賊風,避之有時」,意思就是儘管人體正氣充沛,遇到病邪時,還是需要留神警惕,避之則吉,方為上策。

就扶助正氣而言,起居方面,宜保持室內空氣流通,冷氣溫度不宜調至過低,減少出席公共場所的活動;作息定時,早睡早起,避免遭雨弄濕身體及過度疲勞,做適量運動使身體微微出汗,舒展陽氣,讓陽氣充分發揮防衛的功能;飲食方面,講究飲食均衡,清淡節制,避免進食煎炸、辛辣、燥熱、生冷及肥膩食物,切忌暴飲暴食,保持胃腸清靈;情緒方面,宜保持心境平靜,避免過度思慮,注意情志養生,不要導至情緒過分激烈而損傷「臟氣」。如此保養正氣,可防邪氣入侵。

根據筆者的經驗,常用於新冠康復者的中醫方藥如下:

  1. 杞菊地黃丸:屬補益劑,出自《麻疹全書》.即六味地黃丸(熟地黃、山茱萸、乾山藥、澤瀉、牡丹皮、茯苓)加枸杞子、菊花,能「滋腎養肝明目」,能針對兩目昏花,視物模糊,眼睛乾澀屬「肝腎陰虛」者。
  2. 藿香正氣散:屬祛濕劑,出自《太平惠民和劑局方》,以廣藿香為君藥,配伍大腹皮、白芷、紫蘇、茯苓、半夏曲、白朮、陳皮、薑厚朴、桔梗、炙甘草,能「解表化濕,理氣和中」,適用於惡寒發熱,頭痛,胸膈滿悶,脘腹疼痛,噁心嘔吐,腸鳴泄瀉,舌苔色白厚膩屬於「外感風寒,內傷濕滯」者。
  3. 此外,還包括具有益氣健脾、燥濕化痰功效的六君子湯;辛涼透表、清熱解毒的銀翹散;宣利肺氣、疏風止咳的止嗽散;發汗解表、散風祛濕的荊防敗毒散;和解少陽的小柴胡湯及具有清養肺胃、生津潤燥作用的沙參麥冬湯等。

3. 由於疫情的關係,遙距診症模式應運而生。請分享中醫如何透過遙距診症保證醫療質素和醫療安全?市民於求診時有什麼需要留意的事項?

中醫重視四診合參,透過望、聞、問、切 (inspecting, listening and smelling, questioning and palpating),按照病人的年齡、性別、職業、體質強弱之不同,同時參考季節氣候特點、病邪的屬性和感染力的強弱,判斷病人的病情及病勢;並根據患者發病的緩急輕重,作出最佳的治療方案。

遙距診症側重精準的望診和全面的問診。如情況許可,盡量為醫師提供面部及舌象相片各一。若以手機拍攝的話,相片清晰要點如下:面向自然充足的光線,不背光,不開美圖功能,點按屏幕一下對好焦才按下快門。對話前,宜主動為醫師提供所需資料,包括病史、手術史、中西藥物敏感史,以至正在服用的藥物清單;此外,接種新冠疫苗的劑數及接種日期;確診新冠肺炎或首次轉陰日期等基本資料,亦屬需要,好讓醫師能有效掌握患者的病情及身體狀況,有助提高診療的成效。
