RESUMEN
Total knee replacement (TKR) is associated with a large amount of bleeding; therefore, the prevalence of postoperative anemia is high. In particular, patients with chronic kidney disease (CKD) are more vulnerable to postoperative anemia than are healthy individuals. Accordingly, the effect of intraoperative intravenous ferric derisomaltose (FDI) supplementation on postoperative anemia and blood transfusion volume reduction in patients with CKD was studied. Patients who underwent unilateral TKR between January 2019 and December 2020 were retrospectively reviewed. In analyzing the data, the patients fell into the CKD group (n = 85) and the non-CKD group (n = 106). Each group was divided into a group using FDI and a non-FDI group, and classified into 4 groups. The postoperative hemoglobin level for each postoperative day (POD) was determined as the primary outcome. In addition, the patient transfusion rate, volume of transfusion, and length of hospital stay were set as secondary study outcomes during the period from surgery to discharge. There was no statistically significant difference in hemoglobin levels on PODs 0, 1, 2, 7, and 14 in the CKD group. In the CKD group, the transfusion volume of the FDI group was 0.58 ± 0.91 units per person, which was statistically significantly lower than 1.28 ± 1.28 units of the non-FDI group (P = .01). In the CKD group, the transfusion rate of the FDI group was 30.2%, which was statistically significantly lower than that of the non-FDI group, which was 56.3% (P = .02). This study showed that intravenous FDI supplementation after TKR in CKD patients did not reduce postoperative anemia but was an effective and safe treatment to reduce transfusion volume and transfusion rate. There was no statistically significant difference in hemoglobin levels on POD 0, 1, 2, 7, and 14 in the non-CKD group. In the non-CKD group, the transfusion volume of the FDI group was 0.46 ± 0.88 units per person, which was lower than the 0.56 ± 0.91 units of the non-FDI group, but it was not statistically significant (P = .59). In the non-CKD group, the transfusion rate of the FDI group was 23.0%, which was lower than that of the non-FDI group, which was 31.3%, but it was not statistically significant (P = .37).

During endoscopic orthopedic surgery, epinephrine mixed with irrigation saline is frequently used to improve visualization. By monitoring hemodynamic parameters throughout the procedure, we intended to discover the hemodynamic effect of epinephrine between the normal saline irrigation fluid without epinephrine group (NS) and normal saline irrigation fluid with epinephrine group (EPI). Patients who underwent 1-level lumbar decompression or discectomy surgery without fusion between August 2019 and July 2020 were reviewed retrospectively. The hemodynamic parameters were compared between the NS group and EPI group. As a second endpoint, the incidence of hypotension and hypertension events, expected blood loss, postoperative nausea and vomiting and postoperative epidural hematoma were compared between the 2 groups. The 2 groups were homogeneous in terms of age, sex, weight, height, body mass index (BMI), ASA physical status (ASA PS), and diagnosis. The incidence of hypotension events (67.2 % in the NS group, 45.7 % in the EPI group, P =.015) and severe hypotension events (51.7 % in the NS group, 28.6 % in the EPI group, P = .015) were less frequent in the EPI group. Only epinephrine had a significant protective effect through a multivariable analysis (P = .027, OR = 2.361) and in severe hypotension events, only epinephrine had a significant protective effect through a multivariable analysis (P = .011, OR = 2.818), and EBL was the risk factor through a multivariable analysis (P = .016, OR = 1.002) We believe that the addition of epinephrine to irrigation saline has hemodynamic protective effects in patients who underwent endoscopic lumbar surgery.

RATIONALE: The prone position is commonly used in spinal surgery. There have been many studies on hemodynamic changes in the prone position during general anesthesia. We report a rare case of transient left bundle branch block (LBBB) in a prone position. PATIENT CONCERN: Electrocardiogram (ECG) of a 64-year-old man scheduled for spinal surgery showed normal sinus rhythm change to LBBB after posture change to the prone position. DIAGNOSIS: Twelve lead ECG revealed LBBB. His coronary angio-computed tomography results showed right coronary artery with 30% to 40% stenosis and left circumflex artery with 40% to 50% stenosis. The patient was diagnosed with stable angina and second-degree atrioventricular block of Mobitz type II. INTERVENTION: Nitroglycerin was administered intravenously during surgery. Adequate oxygen was supplied to the patient. After surgery, the patient was prescribed clopidogrel, statins, angiotensin II receptor blocker, and a permanent pacemaker was inserted. OUTCOME: Surgery was completed without complications. After surgery, the transient LBBB changed to a normal sinus rhythm. The patient did not complain of chest pain or dyspnea. LESSON: The prone position causes significant hemodynamic changes. A high risk of cardiovascular disease may cause ischemic heart disease and ECG changes. Therefore, careful management is necessary.

BACKGROUND: Transforaminal epidural steroid injection (TFESI) is a conservative treatment for patients with lumbar disc herniation (LDH). However, there are reports of various complications that can occur after TFESI; among these, paraplegia is a serious complication. CASE: A 70-year-old woman who was unable to lie supine due to low back pain exacerbation during back extension underwent TFESI. After injection, there was pain relief and the patient was able to lie supine; however, paraplegia developed immediately. Magnetic resonance imaging confirmed cauda equina syndrome (CES) due to nerve compression from L1-2 LDH. We determined that the patient's LDH was already severe enough to be considered CES and that the TFESI procedure performed without an accurate understanding of the patient's condition aggravated the disease. CONCLUSIONS: It is important to accurately determine the cause of pain and disease state of a patient to establish a correct treatment plan before TFESI is performed.
