以下是一隻受惠於輸血的狗狗的故事:
Dodge is a 3 year old cocker spaniel from our Flitwick branch he was bought in in September with a swollen neck, the vet suspected that this was due to a foreign body so dodge was sedated and two grass blades were removed from near his tonsils. There was no other obvious wounds so the vet sent dodge home with antibiotics and anti- inflammatories.
Over the next few days dodge started drooling blood at first this was thought to be an abscess that was draining, but due to the significant amount of blood that started draining dodge was admitted for intensive treatment to our Hendon branch.
A CT scan (hundreds of x-rays are taken at once to build a 3d view of the area) was performed. The CT scan showed two large structures one by the right tonsil and one by the right parotid gland. The vet performed a exploratory surgery and found these structures were pockets of clotted blood. This was removed and packed. After surgery dodge was still bleeding and his blood results showed that his red blood cell count was extremely low. Dodge needed an emergency blood transfusion as he had lost so much.
The practice rang vet blood supplies and ordered a bag of packed cells which were sent to Hendon urgently and the blood transfusion was performed.
A further CT scan was performed and a piece of wood was noticed adjacent to the internal carotid (major artery). Dodge underwent a further surgery to remove this piece of wood. Whilst in recover dodge started to bleed so had to have another anaesthetic at 4am to suture and pack the area. Due to the nature of the wound there was a chance the bleeding would continue.
Dodge then needed another blood transfusion due to the continued blood loss so again vet blood supplies were called this time the packed cells had to be the correct type. (e.g. positive or negative) as only the first transfusion a dog has can be either, the second and subsequent ones have to be correctly typed as there could be a reaction to the blood. Dodge needed positive blood so this was sent urgently to Hendon and another transfusion was performed.
The next day dodge had an endoscopy to look at the area and the bleeding had stopped but there was a small amount of oozing.
Dodge stayed on intravenous fluid therapy and also had a plasma transfusion that was ordered from vet blood supplies this was due to his blood levels being extremely low still.
After a lengthy stay in hospital and a couple of set backs dodge has now been able to go home. He's on some medication and is having regular check ups at Flitwick but currently he is doing very well.
The blood that dodge received was from two of our donors Tommy and Henry, their blood was collected on a donor day at our Welwyn garden city branch. As you can see with dodge, blood donation is a life saving process, dodges owners have now been able to take their baby home due to the blood transfusions he has had.
Currently we are in high demand for blood and have a shortage of donors. Which we are trying to rectify with education and advertisement of our blood donor days.

直接抗球蛋白試驗(direct antiglobulin test,簡稱DAT),又叫直接庫氏試驗(direct Coombs’ test),是一種血庫及血液化驗室中常做的檢查,用來測試紅血球的表面是否有抗體。
抗球蛋白試驗由英國免疫學家Robin Coombs提出。當年是血清學剛剛萌芽的時期,當要偵測血清中的ABO抗體時,只要把血清與A型紅血球或者B型紅血球混合,就會有凝集。但要偵測血清中的恆河猴(Rhesus)抗體時,紅血球似乎會被抗體給黏到,卻沒有發生凝集,令偵測很困難。Coombs想到,只要加入的抗人類免疫球蛋白抗體(anti-human globulin)就可以令紅血球凝集了(據聞他是在英國倫敦到劍橋的火車延誤期間想到的,所以下次大家搭車有延誤的話,不妨趁機思考一下醫學問題,可能可以意外地造福醫學界😂)。今天我們知道,這是因為ABO抗體是IgM抗體,有一個五角星型結構,所以可以令紅血球凝集,而恆河猴抗體是IgG抗體,是一個Y字型結構,不能令紅血球凝集,所以需要抗人類免疫球蛋白抗體這種IgM抗體的幫助。
抗球蛋白試驗分為直接與間接兩種,剛才提及偵測血清中恆河猴抗體的方法是屬於間接抗球蛋白試驗(indirect antiglobulin test),我們有空再詳談。直接抗球蛋白試驗則是把病人的紅血球清洗後再加入抗人類免疫球蛋白抗體。如果紅血球發生凝集,就表示病人的紅血球表面本身就黏有抗體,常見的成因包括自身免疫抗體(autoimmune antibodies)、遲發性溶血性輸血反應(delayed haemolytic transfusion reaction)及新生兒溶血猩(haemolytic disease of newborn)。

有些病人在輸血之後很容易有發燒及打顫等反應,應該如何處理呢?
輸血後出現發燒及打顫有幾個可能性,包括非溶血性發熱性輸血反應(febrile non-haemolytic transfusion reaction)、溶血性輸血反應(haemolytic transfusion reaction)、感染引起的敗血反應(septic reaction)等。
醫生一般會先暫停輸血,檢查病人的情況,如果病人維生指數穩定,發燒溫度不很高,沒有注射位置疼痛、腰痛、血尿等的病徵,那最大的可能是非溶血性發熱性輸血反應。確定病人情況穩定後,可以給病人退燒藥,然後再繼續輸血。以後也可以考慮在輸血前使用類固醇及抗組織胺類藥物去預防輸血反應。
非溶血性發熱性輸血反應是由於病人對血液製品中的白血球產生反應(例如產生了HLA抗體),或對血液製品儲存時釋出的細胞激素(cytokines)有反應而引起的。
如果病人經常出現非溶血性發熱性輸血反應,那病人可能已經接觸過不同的HLA蛋白,產生了很多HLA抗體,這情況在經常輸血的病人中特別容易出現。所以對經常出現輸血反應的病人或需要長期輸血的病人,我們可以為他們安排白血球減除血液製品(leukocyte reduced blood product)(下圖),用過濾的方法減少血液製品中的白血球,從而減少輸血反應。
