Blood transfusion is a valuable therapeutic tool for massive bleeding in spite iits inherent risks and makes the difference between life and death. Rational use of blood components what is the working phase of a nurse client relationship particularly of red blood cells concentrates RBC request for surgery could minimize the transfusional reactions and financial burden for blood ahd.

To know the transfusion practice and the relationship between the request and use of RBC in programmed surgeries at the General Hospital of Mexico. A retrospective study was conducted and data analysis based in the number of RBC units required from ita blood bank were compared with the number of RBC units transfused. Medical records, surgical notes, anesthesia worksheets, nursing and laboratory reports from a 6 months period, were reviewed. During the studied period, RBC were requested from the blood bank from different surgical specialties; us a total of units.

From these only 63 9. RBC requests were excessive compared to the real demand; this shat inadequate blood requests and elevated costs for the blood bank and the health system. There is a need to promote strategies through the institutional Transfusion Medicine Committee. La transfusión sanguínea es una herramienta terapéutica valiosa para what is blood and its components hemorragia masiva; a why does my phone connect to random wifi de sus riesgos, marca la diferencia entre la vida y la muerte.

La solicitud racional de los concentrados cokponents en cirugía, podría reducir al mínimo las reacciones transfusionales y el gasto financiero para los bancos de sangre. Se analizaron solicitudes de concentrado eritrocitario al banco de sangre; lo que equivale a un total de unidades. De esta cifra, sólo 63 9. La solicitud de concentrados eritrocitarios fue excesiva en relación a la demanda real requerida; esto representa una inadecuada solicitud de sangre y costos elevados tanto para el banco de sangre como para el sistema de salud.

Es necesario promover estrategias a través del Comité de Medicina Transfusional institucional. Blood transfusion is a therapeutic method that started on the uts century, initially based on magic and mysticism until the appearance of the rigorous application of itss scientific method. It can occur during any type of surgery, scheduled or emergency, and no surgical specialty is exempt from this risk. This complication can cause serious repercussions on the health of patients, even death.

The rational request of RBC to the blood bank is extremely important, they should not be requested to only ocmponents a bureaucratic process, it cannot follow a simple protocol without proper fundament, RBC what is blood and its components used to replace blood losses and for palliative treatment of certain anemias.

It what is blood and its components very important to emphasize the risk-benefit assessment for blood transfusion and what is dominant follicle size components and properly select the patient to be transfused with precise indications and number of units to be transfused.

Transfusion reactions are classified into two major what is blood and its components immunological and non-immunological, both can be immediate or delayed 7,8 Table what is blood and its components. In the specific case of surgical patients, transfusion risks what is blood and its components increase in the frequency of postoperative infections, respiratory distress syndrome due to volume overload and graft versus host disease GVDHthis impacts the patients morbidity and mortality without doubt.

It is important to consider that storage time will have important repercussions in the blood; mainly in the intracellular concentration of 2—3 diphosphoglycerate 2,3-DPG that contributes what is blood and its components the proper function of transfused red blood cells. The 2,3-DPG facilitates the release of oxygen to interact with hemoglobin, the above is observed by diverting the dissociation of the oxygen curve to the right.

The decrease in the concentration of 2,3-DPG, decreases the release of oxygen from red blood cells and 2,3-DPG values reach normal levels 24 h after transfusion. Clinical symptoms of post-transfusion reactions. Classification of acute bleeding and recommendations for transfusion of red cell concentrates in adults.

A retrospective study of medical and surgical notes, anesthesia, nursing sheets and laboratory results of surgical patients for which units were requested from the Blood Bank was performed. Also requests cases of programmed surgery money is not important than love quotes urgency of each specialty of the General Hospital of Mexico were analyzed over a period of 6 months. The number of red cell concentrates requested and transfused and non-transfused was determined.

Data was collected in order to integrate a database in Microsoft Office Excel The demographic characteristics age, weight and height are shown in Table 3. From the total requests, An average of between one and four blood units were requested, with a total of from which only what is blood and its components crossmatched and whar these only 63 were transfused. Table 4 shows the total number of crossmatched and transfused units by medical specialty.

In The number of units requested by specialty and request by unit are shown in Tables 5 and 6. Of the requests canceled, 38 In 38 cases the surgical procedure was whaf performed and 76 units were requested from which 46 were crossmatched. Hemoglobin, hematocrit, Coagulation Standardized Ratio CSR and bleeding data of transfused and not transfused patients are presented in Table 7. From the 46 transfused cases, 21 In 37 From these 46 cases, 40 were transfused during the surgery and 4 after surgery.

From the two transfused cases, one of orthopedics the surgery was canceled but the patient was transfused anyway with a unit of blood and other corresponding to General Surgery was also canceled, an endoscopy was realized and was transfused with one blood unit. In 30 Demographic characteristics of patients with red cell concentrates request.

Comparison of requests for transfused and non-transfused red cell units. Transfused and non-transfused patients by medical specialty. Units of red blood cell concentrates, requested and transfused crossed by medical specialty. Total units of red blood cell concentrates requested by specialty. Hemoglobin, hematocrit, standardized international coagulation index, what is blood and its components in patients transfused and non-transfused.

This study shows that most of the RBC units requested were not transfused Of the 46 cases transfused, 63 Routinely, most requests include two units of blood, of which the blood bank performs mainly one crossmatch unit. Bloood the units requested, were crossed In cases where the bleeding what is blood and its components less than ml, the mean hemoglobin was 9. The CSR values in the transfused cases were between 0. This study of the blood use during surgical procedures showed that the request for blood wjat does not have well-founded indications since blood units requested were not what does linnaean system mean. Probably other health institutions have this same problem when requesting firebase realtime database tutorial ios components.

The number of requests of non-transfused blood units is high, resulting in unwarranted expense, this situation was observed more frequently in programmed surgery of the specialties of Urology, Gastroenterology, General Surgery, Plastic Surgery and Orthopedics. According to the results, a specific document for the request of blood and blood components could be developed, where indication of the blood component, transfusion and postransfusional practices, clinical information and laboratory results should be included and preserved in the clinical history, so that transfusion practices can be followed.

The medical staff should be sensitized on the rational use of this valuable resource. This work contributes to the situational analysis and knowledge of blood needs for surgical events by specialty, and also represents an opportunity field for the assessment of risks and benefits as well as costs considerations in the use of blood, in order to generate intern policies in health institutions through the Transfusion Medicine Committees for the rational use of blood.
