The requests for blood products in elective surgeries exceed actual use, leading to financial wastage and loss of shelf-life. In this study, we assessed the blood transfusion indices in elective surgeries performed in the operating rooms.
In this cross-sectional study, from January to June 2017, a total of 970 adult patients who underwent elective surgeries in the operating rooms of Nemazee hospital, a general referral hospital in southern Iran, were investigated. Demographic, clinical, and laboratory data, such as hemoglobin (Hb), hematocrit (Hct), platelets, prothrombin time (PT), and partial thromboplastin time (PTT) were gathered from medical records. Blood utilization was evaluated using the following indices: cross-match to transfusion ratio (C/T ratio), transfusion probability (T%), transfusion index (TI), and Maximum Surgical Blood Order Schedule (MSBOS).
The overall C/T, T%, and TI ratios were 2.49, 46.6%, and 0.83 for all procedures, and the highest and lowest ratios pertained to the thoracic and cardiac surgeries, respectively. The C/T ratio was ≥2.5 for all surgical procedures except for cardiac surgeries. T% was <30 for thoracic and orthopedics surgeries and ≥30 for other surgical procedures. In all surgical procedures, TI was less than 0.5, except for cardiac surgeries. Also, the MSBOS was about 3 units for cardiac surgeries and ranged from 0.5 to 1 units in other surgeries.
The results of this study showed a high quality blood transfusion practice in cardiac surgeries, possibly due to more focus on this critical ward. Assessing difficulties in the process of reservation, utilization, and preparation of standard protocols and policies are required to improve the blood utilization practice in operating rooms.
择期手术中对血液制品的需求超过实际使用量,导致浪费和保质期损失。本研究评估了手术室择期手术中的输血指标。
本横断面研究于 2017 年 1 月至 6 月期间,调查了伊朗南部综合转诊医院 Nemazee 医院手术室接受择期手术的 970 例成年患者。从病历中收集了人口统计学、临床和实验室数据,如血红蛋白(Hb)、血细胞比容(Hct)、血小板、凝血酶原时间(PT)和部分凝血活酶时间(PTT)。使用以下指标评估血液利用情况:配血与输血比例(C/T 比)、输血概率(T%)、输血指数(TI)和最大手术血液订购计划(MSBOS)。
所有手术的总 C/T、T%和 TI 比值分别为 2.49、46.6%和 0.83,最高和最低比值分别与心胸手术和心脏手术有关。除心脏手术外,所有手术的 C/T 比值均≥2.5。T%在心胸和骨科手术中<30%,在其他手术中≥30%。除心脏手术外,所有手术的 TI 均小于 0.5。此外,心脏手术的 MSBOS 约为 3 单位,其他手术的范围为 0.5 至 1 单位。
本研究结果显示心脏手术中输血质量较高,可能是因为对这个关键病房的关注更多。评估预订、利用和准备标准协议和政策方面的困难,需要改进手术室的血液利用实践。
