Medicine. 2021;100(7):e24678
Abstract
BACKGROUND This study aimed to explore the role of tranexamic acid (TXA) in blood loss control and blood transfusion management of patients undergoing multilevel spine surgery. METHODS In this meta-analysis, a comprehensive search of literatures was performed from PubMed, Embase, Cochrane Library, and Web of Science from inception to June 23rd, 2020. Weighed mean difference (WMD) was used as the effect size for measurement data, and risk ratio for enumeration data. Publication bias was assessed by Begg test. RESULTS Totally 23 studies (11 randomized controlled trials and 12 cohort studies) involving 1621 participants were enrolled in this meta-analysis. The results showed that the administration of TXA can significantly decrease the intraoperative [WMD: -215.655, 95%CI: (-307.462, -123.847), P < .001], postoperative [WMD: -69.213, 95%CI: (-104.443, -33.983), P = .001] and total [WMD: -284.388, 95%CI: (-437.66, -131.116), P < .001] volumes of blood loss of patients undergoing multilevel spine surgery. It can also significantly reduce the intraoperative [WMD: -333.775, 95%CI: (-540.45, -127.099), P = .002] and postoperative [WMD: -114.661, 95%CI: (-219.58, -9.742), P = .032] volumes of transfusion. In addition, TXA was found to significantly increase the preoperative [WMD: 0.213, 95%CI: (0.037, 0.389), P = .018] and postoperative [WMD: 0.433, 95%CI: (0.244, 0.622), P < .001] hemoglobin levels as well as the preoperative platelet count [WMD: 14.069, 95%CI: (0.122, 28.015), P = .048]. CONCLUSION The administration of TXA can effectively reduce blood loss and transfusion, and improve hemoglobin levels and preoperative platelet count in patients undergoing multilevel spine surgery.

Abstract
BACKGROUND Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common sleep-related respiratory disease. Despite reports of low-temperature plasma radiofrequency ablation of tonsils and adenoids for the treatment of OSAHS, the effects on lung function and quality of life are unclear. AIMS This study aims to explore the effects of low-temperature plasma treatment on pulmonary function in children with OSAHS. METHODS A total of 110 children with OSAHS were included in this prospective study. Low-temperature plasma radiofrequency treatment and routine surgical treatment were performed in group A and group B, respectively. Maximal voluntary ventilation (MVV), forced vital capacity (FVC), and total lung capacity (TLC) were measured. OSA-18 survey was used to evaluate the quality of life 1 year after operation. RESULTS Group A had significantly higher effective treatment rate (P < 0.05) and lower operative period, bleeding volume, visual analog score, pseudomembrane detachment time, and time required to feed after operation than group B (all P < 0.001). There were no significant difference in the incidence of postoperative complications between the groups and MVV, FVC, and TLC between the groups before and after operation (all P > 0.05), and the above indexes in both groups were significantly increased after operation (all P < 0.05). OSA-18 scores in group A were significantly lower than group B after operation (P < 0.001). CONCLUSIONS Low-temperature plasma technique performed in OSAHS children has a good clinical effect, which can reduce the operation time, intraoperative blood loss, postoperative pain, pseudomembrane detachment time, hospitalization time, and improve pulmonary function and quality of life.

Medicine. 2016;95((27)):e4122.
Abstract
INTRODUCTION Because allogeneic blood transfusion carries a risk of serious complications, erythropoietin (EPO) has been used in patients scheduled for total hip or knee arthroplasty in an effort to reduce the need for allogeneic blood transfusion; however, its efficacy, cost-effectiveness, and safety are still controversial. The purpose of this review was to determine the hematopoiesis-promoting effect and potential complications, as well as the cost-effectiveness, of preoperative use of EPO in patients scheduled for total hip or knee arthroplasty. METHODS We searched MEDLINE, EMBASE, Cochrane, and ClinicalTrials.gov databases for relevant literature from 2000 to 2015. Risk of bias was assessed for all included studies and data were extracted and analyzed. RESULTS Preoperative use of EPO was associated with lower exposure to allogeneic blood transfusion (odds ratio = 0.41) and higher hemoglobin concentration after surgery (standardized mean difference = 0.86, P < 0.001). Complications were not generally reported, but there was no significant difference between the group with and without EPO based on given data. Cost-effectiveness was also summarized but was not conclusive. CONCLUSION Preoperative administration of EPO reduces the requirement for allogeneic blood transfusion and increases hemoglobin level after surgery. The studies of cost-effectiveness were not conclusive. Further studies and guidelines specific to blood management in the perioperative stage of total knee and hip arthroplasty are expected.

Abstract
BACKGROUND AND OBJECTIVE Extreme haemodilution occurring with cardiopulmonary bypass imposes a primary risk factor for blood transfusion in small adult cardiac surgical patients. Priming of the cardiopulmonary bypass circuit with patients' own blood [retrograde autologous priming (RAP)] is a technique used to limit haemodilution and reduce transfusion requirements. We designed this study to evaluate the effects of RAP on reducing perioperative blood transfusion in small adults. METHODS One hundred and twenty patients with a body surface area of less than 1. 5 m undergoing first-time, nonemergency cardiac surgery were randomized to either the standard priming group or the RAP group. All patients followed strict transfusion criteria. Homologous transfusion, haematocrit, plasma colloid osmotic pressure and postoperative clinical outcomes were evaluated perioperatively. RESULTS Patient characteristics and operative parameters were equal for patients in both groups. With autologous priming, a mean volume of 614. 8 +/- 138. 8 ml of priming solution was replaced with autologous blood. This allowed a significantly higher haematocrit value during cardiopulmonary bypass (P < 0. 05). Red blood cell transfusion was necessary in 83. 3% of patients of the standard priming group on pump, whereas only 26. 7% of patients of the RAP group required transfusion (P < 0. 01). The overall transfusion rate of the RAP group was significantly less than that in the standard priming group during the hospitalization (90. 0 vs. 50. 0%, P < 0. 01). Amongst patients who received transfusion on pump, the number of homologous units of packed red blood cells was less in the RAP group than that in the standard priming group intraoperatively and perioperatively (0. 94 +/- 0. 32 vs. 1. 48 +/- 0. 68 units, P = 0. 03; 1. 24 +/- 0. 54 vs. 1. 69 +/- 0. 69 units, P = 0. 15). Ten minutes after aortic cross-clamp, colloid osmotic pressure was reduced by 39. 7 +/- 2. 8% in the standard priming group and by 28. 6 +/- 3. 2% in the RAP group (P < 0. 05). Clinical outcomes were similar with respect to pulmonary, renal and hepatic function, length of ICU stay and hospital stay. CONCLUSION RAP resulted in a significant decrease in intraoperative haemodilution and conserved the use of blood. This technique should be considered for patients with a small body surface area (<1. 5 m) undergoing open heart surgery.

Abstract
BACKGROUND The objective of the study was to evaluate the quality of salvaged blood retrieved during craniotomy after the processing by autotransfusion devices and to compare the processing effects of 2 autotransfusion devices: ZITI-2000 (Jingjing Medical Equipment Limited, Beijing, PR China) and BRAT 2 (Cobe Cardiovascular Inc, Division of Sorin Biomedica Arvada Co, Arvada, Colo). METHODS Twenty-four patients scheduled for elective craniotomy were randomly allocated into 2 groups, and 1 of the 2 autotransfusion devices (ZITI-2000 and BRAT 2) was used for each group. The blood samples were collected, washed, and tested for select blood components. The efficacy of centrifugation and washing was assessed by determining the ER of PLTs, WBCs, K+, and fHb. The morphology of the washed erythrocytes and the 2-week-old PRBCs was evaluated by means of SEM. RESULTS Extensive hemolysis was observed in the collected blood of both ZITI-2000 and BRAT 2 groups, with fHb being 464. 8 +/- 111. 6 and 459. 0 +/- 91. 6 mg/dL, respectively. The ERs of PLTs, WBCs, K+, and fHb were >35%, >80%, >90%, and >90%, respectively. Although some shape-changed red cells were observed in the washed blood, discocytes were the dominant form in both groups, with the percentages of discocytes being 58. 0% +/- 8. 0% and 59. 7% +/- 8. 3%, respectively. A greater number of shape-changed red cells were found in 2-week-old PRBCs (P < . 01). CONCLUSION For craniotomies, the quality of salvaged blood processed by both devices (ZITI-2000 and BRAT 2) is equally satisfactory. Although extensive hemolysis is noted in the salvaged blood, IBS can be effectively and safely used.
