Objectives: The amount of blood transfusion after knee arthroplasty seem to vary in different reported study. We carried out a retrospective study to analysis pre-operative risk factors for blood transfusion in patient whom underwent knee arthroplasty in our institution. Methods: A retrospective study of 190 patients treated with 194 procedure (186 unilateral knee arthroplasty, 4 bilateral knee arthroplasty) from November 2014 to October 2015 was analyzed. A univariate analysis was performed to establish the relationship between all variables and the need for postoperative transfusion. Variables that were determined to have significant relationship were include in a multivariable analysis.. Results: The univariate analysis revealed a significant relationship between need for postoperative blood transfusion and preoperative hemoglobin levels, surgical technique, arthrotomy approach, DVT prophylaxis, operative blood loss, surgical technique and surgeon experience. The multivariate analysis identified a significant relationship between need for transfusion and preoperative hemoglobin level, surgical technique and operative blood loss. Patients with a preoperative hemoglobin less than 12 g/dL had a 5.1 times greater risk of having a transfusion than those with a hemoglobin level ≥ 12 g/dL. The surgical technique with computer assisted surgery had a 0.15 times lesser risk of having a transfusion than those with the conventional technique. Conclusion: The preoperative hemoglobin level < 12 g/dL was shown to increase risk of the need for blood transfusion after knee arthroplasty, while computer assist surgery total knee arthroplasty was shown to decrease risk of blood transfusion. We suggest that patients with preoperative hemoglobin < 12 g/dL need to be crossmatching PRC in pre-operative steps.

Background Splenectomy is sometimes indicated for portal hypertension caused by cirrhosis, which is a risk for hepatic carcinogenesis. This study aimed to identify risk factors for hepatocellular carcinoma (HCC) development after splenectomy. Methods This retrospective study included 65 patients who underwent splenectomy for portal hypertension between 2009 and 2017. Cox regression analyses were performed to identify factors related to HCC development after splenectomy. The predictive index for HCC development was constructed from the results of multivariate analysis, and 3 risk-dependent groups were defined. Discrimination among the groups was estimated using Kaplan-Meier curves and the log-rank test. Results Post-splenectomy, 36.9% of patients developed HCC. In the univariate analysis, the etiology of cirrhosis (hepatitis C virus antibody, P = .005, and hepatitis B surface antigen, P = .008, referring to non-B and non-C patients, respectively), presence of HCC history ( P < .001), and preoperative hemoglobin level ( P = .007) were related to HCC development, and the presence of HCC history ( P = .002) and preoperative hemoglobin level ( P = .022) were independent risk factors. The predictive index classified three groups at risk; the hazards in each group were significantly different (low vs middle risk, P = .035, and middle vs high risk, P = .011). Discussion The etiology of cirrhosis, presence of HCC history, and hemoglobin level were associated with HCC development after splenectomy. The predictive model may aid in HCC surveillance after splenectomy for patients with portal hypertension.

Abstract Background This study was designed to explore the prevalence and risk factors of preoperative deep venous thromboembolism (DVT) in Chinese elderly with hip fracture. Methods From January 1, 2012, to December 31, 2018, 273 elderly patients over 70 years old with elective hip surgery were collected from the electronic medical records. Collected data included demographic characteristics, comorbidities, ASA classification, types of previous operations, types of anesthesia, operation time, fracture to operation time, preoperative hemoglobin level, anemia, blood-gas analysis, cardiac function, whether transfusion, preoperative hospitalization, postoperative hospitalization, electrocardiograph, lower limb venous ultrasonography and total hospitalization time. Results In these 273 patients, 15(5.6%) had ultrasonography evidence of DVT in affected limbs before surgery. Three of all patients received an temporary inferior vena cave filter placement preoperatively. Fracture to surgery time, preoperative hemoglobin level, anemia, preoperative hospitalization, pulmonary disease and total hospitalization time were statistically different between DVT group and non-DVT group (P < 0.05 for all). Moreover, preoperative anemia (OR: 0.144, 95%CI: 0.026–0.799, P = 0.027) and total hospitalization time (OR: 1.135; 95%CI: 1.023–1.259, P = 0.017) were the two independent risk factors for preoperative DVT. Conclusion Preoperative anemia and total hospitalization time were independent risk factors for venous DVT in Chinese elderly with hip fracture.

Preoperative Hemoglobin Level

Aim: To find out the incidence and correlation of preoperative hemoglobin level (Hb %) with hemoperitoneum in cases of ectopic pregnancy (EP). Methods: This was a prospective study carried out in Tribhuvan University Teaching Hospital (TUTH), Nepal during the period of 5 years; 15 April 2002-14 April 2007 (Baisakh 2059 - Chaitra 2063). All the cases of hemoperitoneum from rupture of EP confirmed at laparotomy were analyzed. Unruptured ectopic EP undergoing medical management or ruptured organized EP forming tubo-ovarian mass and ruptured rudimentary horn pregnancy without hemoperitoneum were all excluded. Datas were collected from patient's interview, reviewing the operation record and record file. Result: Of the total 167 EP constituting 0.963 % of all deliveries, managed during the five years period, 150 (90%) cases with hemoperitoneum were analyzed. Further excluding five cases not mentioning the amount of hemoperitoneum 145 [ < 1500ml (98) or >1500ml ->3000ml (47)] was categorized to have different degrees of anaemia was ascertained in 90 (62.1%): Severe (13), moderate (55) and mild (22). Results depicted a negative (inverse) correlation between pre operative Hb level and hemoperitoneum. Conclusion: In conclusion there is negative (inverse) correlation between pre-operative Hb percentage and hemoperitoneum which is statistically significant.
