OVERVIEW OF ANEMIA AFTER SCOLIOSIS SURGERY IN THE INTENSIVE CARE UNIT (ICU) SOEHARSO ORTHOPEDIC HOSPITALINDONESIA

Abstract

Anemia is a condition where the hemoglobin concentration is lower than normal. This condition reflects the lack of the normal number of erythrocytes in the body's circulation and consequently the amount of oxygen delivered to the body's tissues is also reduced. Miller & Thompson (2019) scoliosis comes from the Greek word "scoliosis" which means crooked. Scoliosis is a complex three-dimensional deformity of the spine characterized by a lateral deviation of at least 10 degrees with spinal rotation and is usually associated with a reduction in the normal kyphotic curvature of the spine / hypokyphosis. The cause of bleeding in spinal surgery usually occurs more in cases of rigid scoliosis, pedicle subtraction osteotomy and vertebral column resection often referred to as triple column osteotomy and is considered a procedure with a high risk of complications with massive blood loss, reaching more than 10 liters (Jun. 2019). Based on its classification, this type of research is retrospective descriptive research. studies that discuss one or more variables separately, one-by-one, but do not examine the relationship between these variables, using the observation method with the subject being observed by looking at past conditions (Harlan &Sutjiati, 2022). Using total sampling technique in sampling, the population is the medical records of patients admitted to the ICU, postoperative diagnosis of scoliosis with anemia, the sample size is 58 patient medical records. The variables observed were: indications for ICU admission and postoperative scoliosis, the inclusion criteria were medical record data for postoperative scoliosis patients with anemia admitted to the ICU for the period January 1 - December 31, 2022 and patients with the first scoliosis surgery. Based on this study, the following results were obtained: Most respondents were female (81%), the average age of respondents was 17 years. The most common type of scoliosis is adolescence idiopathic scoliosis (89.7%). The most Lenke classification is Lenke 3 (44.8%), the most types of surgery are stabilization, fusion, discectomy, laminectomy and osteotomy (56.9%). The duration of surgery was mostly 180-240 minutes (46.6%) with an average duration of surgery of 257 minutes, the average amount of bleeding was 884.5 ml, the average preoperative Hb was 13.3g/dL, the average postoperative Hb was 8.8 g/dL. The average postoperative Hemoglobin decrease was 5.3 g/dL, patients who were given blood transfusions (87.9%) with an average of 2.9 bags per patient, the most common type of transfused blood was PRC (90.2%).
