A Survey on Transfusion Status in Orthopedic Surgery at a Trauma Center.

Arch Bone Jt Surg 2016 Jan;4(1):70-4

Anesthesiology Research Center, Guilan University of Medical Sciences, Rasht, Iran.

Background: Increased costs and mortality associated with inappropriate blood transfusions have led to investigations about blood request and blood transfusion techniques. We investigated the transfusion status in patients who underwent orthopedic surgery in Poursina Hospital (Rasht, Iran) to optimizing blood usage and determine if a scheduled transfusion program for every orthopedic surgery could improve blood transfusion management.

Method: In this descriptive-prospective study, all orthopedic surgeries in Poursina Hospital, Rasht, between April to June 2013 were reviewed. All patient information was recorded, including: demographics, type of surgery, hemoglobin level, cross-match test, duration of surgery, and blood loss, and transfusion. Based on the one-way ANOVA and independent samples test analysis, cross-match to transfusion ratio and transfusion possibility, the transfusion index, and maximal surgical blood order schedule were calculated to determine blood transfusion status.

Results: Among 872 selected orthopedic surgery candidates, 318 of them were cross-matched and among those, 114 patients received a blood transfusion. In this study, the cross-match to transfusion ratio was 6.4, transfusion possibility 36.47%, transfusion index 0.6, and maximal surgical blood order schedule 0.9.

Conclusion: We found that blood ordering was moderately higher than the standard; so it is highly recommended to focus on the knowledge of evidence based on transfusion and standard guidelines for blood transfusion to avoid over-ordering.

Hemodynamic and Arterial Blood Gas Parameters during Cemented Hip Hemiarthroplasty in Elderly Patients.

Background: Patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (BCIS) which is a leading cause of intraoperative complications. The purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.

Methods: Cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. All patients were catheterized with a radial artery catheter to assess mean arterial pressure (MAP) and arterial blood gas (ABG) in these time points: just before cementation, just after cementation (0th), 5 min (5th) and 10 min (10th) after cementation, and at the end of surgery (END). Also, systolic and diastolic blood pressure (SBP & DBP), heart rate and any arrhythmia or cardiac arrest was evaluated.

Results: Seventy-two patients (33 females, 39 males; mean age: 66.8±7 years) were evaluated. All parameters changed during cementation with a significant drop in MAP, SBP, and DBP immediately after cementation and pH and base excess decreased significantly (P<0.001) with no changes in O2 saturation. Mean heart rate rose until the 5th and then decreased dramatically with no bradycardia presentation. During cementation, 12 patients showed arrhythmia, but no cardiac-arrest was observed.

Conclusions: Under strict observation of a anesthesiology care team, hemiarthroplasty can be a safe method for femoral neck fracture in elderly osteoporotic patients without severe cardiopulmonary compromise.
