MINI: Intraoperative cell salvage (ICS) is used to reduce blood loss in scoliosis spinal fusion. We report one case of hemolysis induced acute renal failure following ICS. This is the first reported case of acute renal failure associated with hemolysis following ICS in a scoliosis patient with sickle cell trait.
Case report.
To describe a novel presentation of acute renal failure associated with hemolysis after intraoperative cell salvage (ICS) in a neuromuscular scoliosis patient with sickle cell trait (SCT).
Hemolysis-associated acute renal failure after ICS in patients with SCT has not been previously reported. Sickle cell disease is regarded as a relative contraindication for ICS due to the risk of red blood cell sickling in the hypoxic cell saver reservoir. A previous case series demonstrated successful ICS reinfusion after elective caesarean section in two patients with SCT. However, a decision to not reinfuse ICS collected blood due to increased sickling after blood processing was reported in general surgery.
A 14-year-old female with Group I neuromuscular scoliosis underwent a navigated T3-S1posterior spinal instrumentation fusion. Three hundred milliliters of blood collected by ICS was reinfused intraoperatively along with two units of packed red blood cells.
Postoperatively, the patient had delayed emergence from the general anesthetic and gross hematuria was observed in the urinary catheter bag. The patient was transferred to the intensive care unit and was treated successfully for hemolysis-induced renal failure.
Given the potential seriousness of hemolysis-associated acute renal failure associated with ICS, we recommend against the use of ICS in patients with SCT.
MINI:术中细胞回收(ICS)用于减少脊柱融合术的失血量。我们报告了一例 ICS 后引起溶血的急性肾衰竭病例。这是首例报道的伴有镰状细胞特征的脊柱侧凸患者 ICS 后发生溶血相关急性肾衰竭的病例。
病例报告。
描述一例伴有镰状细胞特征的神经肌肉脊柱侧凸患者 ICS 后发生溶血相关急性肾衰竭的新表现。
ICS 后伴有镰状细胞特征的患者发生溶血相关急性肾衰竭尚未有报道。由于在低氧细胞保存器中红细胞镰状化的风险,镰状细胞病被认为是 ICS 的相对禁忌症。以前的病例系列研究表明,在两例镰状细胞特征的患者行择期剖宫产术后,成功进行了 ICS 再输注。然而,在普通外科手术中,由于血液处理后镰状化增加,报告了决定不进行 ICS 回收血液的再输注。
一名 I 组神经肌肉脊柱侧凸的 14 岁女性患者接受了导航 T3-S1 后路脊柱器械融合术。术中重新输注了 300 毫升通过 ICS 收集的血液,同时输注了 2 个单位的浓缩红细胞。
术后,患者全麻苏醒延迟,并在导尿管袋中观察到肉眼血尿。患者被转至重症监护病房,并成功治疗了溶血引起的肾衰竭。
鉴于 ICS 相关溶血引起的急性肾衰竭的潜在严重性,我们建议不将 ICS 用于镰状细胞特征的患者。
