RESUMEN
BACKGROUND: Autologous blood transfusion device has been widely used in the clinic, reduces al ogeneic blood transfusion, and avoids the occurrence of blood transfusion complications, and effectively improves the patient’s blood safety, but the application of autologous blood transfusion after total hip arthroplasty has been seldom reported. OBJECTIVE: To discuss the safety and effectiveness of autologous blood transfusion after total hip arthroplasty. METHODS: 200 patients were treated by primary unilateral total hip arthroplasty from March 2013 to March 2015. They were randomly divided into two groups. 127 patients in the autologous blood transfusion group received autologous blood transfusion by a drainage tube. 73 patients in the negative pressure drainage bal group received a negative pressure drainage tube. The standard for al ogeneic blood transfusion after replacement was hemoglobin 0.05). Hemoglobin levels were significantly higher in the autologous blood transfusion group than in the negative pressure drainage bal group at 1 day after replacement (P < 0.05). In the autologous blood transfusion group, autologous blood transfusion volume was averagely 324.2 mL. Al ogeneic blood transfusion volume was averagely 146.7 mL in 31 patients. No reaction was found after autologous blood transfusion. In the negative pressure drainage bal group, 49 patients received al ogeneic blood transfusion (averagely 261 mL). The volume and proportion of al ogeneic blood transfusion were significantly lower in the autologous blood transfusion group than in the negative pressure drainage bal group (P < 0.05). Among patients receiving al ogeneic blood transfusion, seven patients affected pyrogenetic reaction during blood transfusion. These findings suggested that autologous blood transfusion is simple and effective, can effectively reduce the volume and reaction of al ogeneic blood transfusion after total hip arthroplasty and avoid blood-borne diseases, with good prospects.
RESUMEN
For the purpose of clinical application, this article presents a preliminary observation on the arterial supply of the knee joint in 57 fixed and fresh lower limbs, adopting topography, arterial cast, a rteriography and clearing of the specimens. There are more variations and common-stems of the articular branches on the right side. Each artery of the knee has its own characteristic morphology and special distribution. Whenever a local area has several sources of arterial supply, relationships between primary and secondary, superficial and deep arteries exist. According to their caliber, arteries of the knee may be divided into 3 groups. Besides the possibility for evaluating the degree of blood supply, variations in caliber are indications for estimating the size of neighboring arteries. Arterial blood supply of the whole knee area is comparatively even and symmetrical. The level of origin of all arteries supplying the Same area of the knee joint is constant, bearing a certain relation to one another. Besides, a brief discussion about the concept of "pure articular branch" and "musculoarticular branch", collateral arterial anastomosis, local "nonvascular area", relationship between prepatellar arterial network and the blood supply of patella is given.
