In orthopedic surgery, bleeding is an inevitable side effect. The study's aim was to provide estimated blood loss values in various orthopedic procedures and take a step towards developing statistically reliable formulae. This can provide blood loss values in orthopedic surgery, which will be a very good tool for operative planning.
We reviewed case notes of 282 patients in a UK based trauma center from December 2020 to March 2021,who had undergone a various orthopedic procedures. The results were analyzed using SPSS version 25.
Most common fracture was neck of femur (37.5%)followed by intertrochanteric fractures(27.6%). Paired -test was used, and there is good evidence (t281 = 14.957, p = 0.000) that intraoperative transfusions increased HB levels in patients (t281 = 14.957, p = 0.000) by an average of 1.331 points, with a 95% confidence interval of 1.156-1.506. As a result, the variation between the Pre-op and Post-op HB levels is statistically important but minimal. We can see that the mean blood loss is statistically different in different age groups (0.03) of patients and by the existence of co-morbids using analysis of variance (0.04). The average number of days spent in the hospital varies by surgical type (0.01) performed on patients.
Orthopedic surgery can be associated with high levels of blood loss. There is a significant relation between fracture form and age groups, change of wound dressing (COD), use of a tourniquet, and drain insertion, no connection was noted between gender and fracture types.
在骨科手术中，出血是不可避免的副作用。本研究的目的是提供各种骨科手术中的估计失血量，并朝着开发具有统计可靠性的公式迈出一步。这可以提供骨科手术中的失血量值，这将是手术规划的一个非常好的工具。
我们回顾了2020年12月至2021年3月在英国一家创伤中心接受各种骨科手术的282例患者的病历。使用SPSS 25版对结果进行分析。
最常见的骨折是股骨颈骨折（37.5%），其次是转子间骨折（27.6%）。采用配对检验，有充分证据（t281 = 14.957，p = 0.000）表明术中输血使患者血红蛋白（HB）水平平均提高1.331个点，95%置信区间为1.156 - 1.506。因此，术前和术后HB水平之间的差异在统计学上具有重要意义，但很小。我们可以看到，不同年龄组患者的平均失血量在统计学上存在差异（0.03），并且通过方差分析可知合并症的存在也会导致差异（0.04）。患者住院的平均天数因所进行的手术类型而异（0.01）。
骨科手术可能伴有大量失血。骨折类型与年龄组、伤口换药（COD）、止血带的使用和引流管插入之间存在显著关系，未发现性别与骨折类型之间存在关联。
