简要总结
The objective of this study was to assess the effectiveness of the intraoperative periarticular solution in reducing blood loss and minimizing transfusion requirements in patients with femoral neck fractures who underwent hemiarthroplasty.
详细描述
Hip fractures in the elderly represent a significant public health challenge, marked by elevated rates of morbidity and mortality. The worldwide increase in life expectancy has led to a corresponding rise in the incidence of hip fractures. Notably, increased perioperative blood loss has been identified as a critical factor that heightens the risk of complications and mortality. Consequently, contemporary research efforts have focused on addressing this pivotal issue. Various strategies have been developed, including controlled hypotensive anesthesia and the utilization of pharmacological agents aimed at reducing the perioperative blood products. The necessity for the efficacy of tranexamic acid (TXA) in mitigating blood loss has been well-established across numerous surgical specialties. This study is motivated by the need for an effective and safe approach to perioperative blood salvage. To date, there appears to be a lack of research examining the effectiveness of the intraoperative periarticular injection technique (100 mL periarticular solution comprising 200 mg of bupivacaine (40 mL), 60 mg of ketorolac (2 mL), 8 mg of dexamethasone (2 mL), 2 mg of 1:1000 epinephrine (2 mL), and standard saline solution (54 mL). This solution was prepared in two 50 mL syringes. The first syringe containing 50 mL of the cocktail was injected into the capsule and gluteal muscles before femoral stem insertion. Following joint capsule closure, the second syringe containing 50 mL of the periarticular injection cocktail was infiltrated into the fascia lata muscle, subcutaneous tissue, and wound layers) regarding blood loss reduction. Therefore, this study aims to investigate the following questions: 1) Is intraoperative periarticular injection an effective technique for minimizing blood loss in patients with hip fractures? and 2) What proportion of the salvaged blood loss can be attributed to hidden blood loss?

研究组 & 干预措施
Periarticular injection group
Patients in the periarticular injection group were administered a 100 mL periarticular solution comprising 200 mg of bupivacaine (40 mL), 60 mg of ketorolac (2 mL), 8 mg of dexamethasone (2 mL), 2 mg of 1:1000 epinephrine (2 mL), and standard saline solution (54 mL). This solution was prepared in two 50 mL syringes. The first syringe containing 50 mL of the cocktail was injected into the capsule and gluteal muscles before femoral stem insertion. Following joint capsule closure, the second syringe containing 50 mL of the periarticular injection cocktail was infiltrated into the fascia lata muscle, subcutaneous tissue, and wound layers.

结局指标
主要结局
Total Blood Loss
时间窗: Preoperative and postoperative hematocrit (HCT) and hemoglobin (Hb) levels measured over the first three days
The calculation of Total Blood Volume (TBV) was conducted using the following manner: TBV= k1 x H3 + k2 x W+ k3 For males, k1 = 0.3669, k2 = 0.03219, and k3 = 0.1833; for females, k1 = 0.3561, k2 = 0.03308, and k3 = 0.1833; H=height (m) and W=weight (kg) The calculation of Total blood loss (TBL) was conducted using the Gross formula method as follows: TBL= TBV x (Preoperative HCT (Hematocrit) - Postoperative 3-day HCT) / Mean HCT
次要结局
- Hidden Blood Loss(Postoperative first three days)
