Abstract

OBJECTIVE To explore the effects of two different hemostasis methods, namely, arterial compression devices and vascular closure devices, in the ischemic cerebrovascular intervention to provide a theoretical basis for clinical selection of hemostasis methods. METHODS A total of 302 patients who underwent ischemic cerebrovascular intervention in our hospital from January 2016 to December 2020 were selected as the research subjects and randomly divided into the control group (n = 151) and the observation group (n = 151). The patients in both groups underwent cerebrovascular intervention. The patients in the control group were treated with an artery compressor for hemostasis after the operation, while those in the observation group were treated with vascular closure devices for hemostasis. The hemostatic indexes and vascular parameters at the puncture site before and after the operation were compared between the two groups. The comfort level of the patients was assessed at 6, 12, and 24 h after the operation with the Kolcaba Comfort Scale score, and the postoperative complications were recorded. RESULTS There was no significant difference in the success rate of hemostasis between the two groups (p > 0.05). The hemostatic time and immobilization time of (2.69 ± 0.62) min and (4.82 ± 0.93) h in the observation group were lower than those in the control group with (16.24 ± 3.58) min and (7.94 ± 1.86) h (p < 0.05). The differences in the minimum inner diameter of the puncture site and its nearby vessels and the peak velocity of blood flow between the two groups before and after the operation were not statistically significant within or between groups (p > 0.05). The scores of the Kolcaba comfort scale in the observation group (80.16 ± 8.49) and (93.65 ± 9.26) at 6 and 12 h, respectively, after the operation, were higher than those in the control groups (72.08 ± 7.54) and (85.49 ± 8.63) (p < 0.05). The 24 h postoperative Kolcaba comfort scale score was (97.54 ± 9.86) in the observation group and (96.82 ± 9.64) in the control group, and the difference was not statistically significant (p > 0.05). In the control group, there were 7 cases of dysuria, 12 cases of low back pain, 14 cases of sleep disorder, 20 cases of mental stress, and 5 cases of wound bleeding, and the total incidence of complications was 38.41% (58/151). In the observation group, there were 4 cases of dysuria, 8 cases of low back pain, 10 cases of sleep disorder, 14 cases of mental stress, and 3 cases of wound bleeding, and the total incidence of complications was 25.83% (39/151). The total incidence of complications in the observation group was lower than that in the control group (p < 0.05). CONCLUSION For patients with ischemic cerebrovascular disease undergoing femoral artery puncture intervention, the use of vascular closure devices can stop the bleeding quickly, which can significantly shorten the bleeding time, and the postoperative braking time of patients is short, with high comfort and fewer complications.

Abstract

OBJECTIVE The aim of this study is to analyze the clinical effect of small bone-window craniotomy with microscope combined postoperative ICP monitoring, and further explore an appropriate treatment for HICH patients. METHODS One hundred fifty patients with HICH were selected according to inclusion and exclusion criteria and divided into 3 groups at random, 50 each group. Patients in 3 groups were treated with conventional craniotomy, small bone-window craniotomy and small bone-window craniotomy combined ICP monitoring respectively. The surgical efficiency, treatment effect and outcomes were recorded and analyzed. RESULTS The intraoperative blood loss and operation time of small window groups were significantly less than that of conventional group, and the hematoma clearance rate in small window groups were significantly higher than in conventional group (P < 0.05). Compared with conventional group, the hospital stays and mannitol dose used were less in small window groups and least in small window combined ICP monitoring group (P < 0.05). The complication rate in small window combined ICP monitoring group was 10%, which was significantly lower than in conventional group (26%, P < 0.05), while no significant difference was found between small window group (18%) compared with the other 2 groups respectively (P > 0.05). The difference of morality rate between 3 groups wasn't significant (P > 0.05). Three treatment significantly increased the Barthel index score, and the improvement of small window combined ICP monitoring group was significantly higher than in other 2 groups respectively (P < 0.05), while the difference between this two groups wasn't significant (P > 0.05). CONCLUSION Small bone-window craniotomy is more efficient and convenient than conventional craniotomy in the treatment of HICH. In the meantime, small bone-window craniotomy simultaneous with ICP monitoring significantly improved clinical effect and treatment outcomes of HICH patients.

Abstract

Sickle Cell Disease (SCD) is a chronic hemolytic disorder associated with frequent pain episodes, end organ damage and a shortened lifespan. Currently there exist no disease specific targeted therapies for the treatment of acute vaso-occlusive crisis (VOC) and management with analgesics and hydration is purely supportive. Improvement in understanding of disease pathophysiology has resulted in a great interest in disease modifying novel therapies and many are being evaluated in clinical trials. Here we report the results from the pre-specified mid-point analysis of the Phase 2 study of Intravenous Gamma Globulin (IVIG) for the treatment of acute VOC in patients with SCD and lessons learned.

Abstract

BACKGROUND Preoperative platelet rich plasma (PRP) harvest has been used in cardiopulmonary surgery for more than 10 years. There is no previous study dealing with PRP in bilateral total hip replacement. This study was to investigate the effects of PRP on blood saving and blood coagulation function in patients with bilateral total hip replacement. PATIENTS AND METHODS A prospective, randomized, clinical trial was conducted. Sixty patients were enrolled, including 30 patients undergoing PRP in the PRP group and 30 controls. The surgery time, total transfusion volume, blood loss, allogenic blood transfusion, autologous blood transfusion, urine volume, drainage volume, some blood parameters (including Fibrinogen, D-dimer, Prothrombin time, international normalizedratio, activated partial thromboplastin time, Platelet, Haemoglobin B), thrombelastogram (TEG) and blood-gas parameters were studied in the perioperative stage. The measurement data were analyzed statistically. RESULTS There was no statistical difference between the two groups in baseline characteristics, surgery time, total transfusion volume, blood loss, autologous blood transfusion, etc. Allogenic blood transfusion in the PRP group was less than the control group with statistical difference (p=0.024). Fibrinogen in the PRP group was higher than the control group (p=0.008). Among the TEG indicators, activated clotting time and coagulation time K in the PRP group were less than the control group. Clotting rate and maximum amplitude in the PRP group were higher. The blood-gas parameters presented no statistical difference. CONCLUSION The results suggested that PRP probably played a positive role in blood coagulation function as well as blood saving in patients with bilateral total hip replacement.

Abstract

BACKGROUND Adolescent idiopathic scoliosis surgery is often associated with significant blood loss and blood transfusion. In this clinical trial, the authors investigated the efficacy of reducing blood loss and allogeneic blood transfusion by using batroxobin, tranexamic acid (TXA) and the combination of the two agents. METHODS 80 adolescent patients undergoing scheduled idiopathic scoliosis surgery were randomly divided into four groups to receive 0.9% saline (group A), batroxobin (group B), TXA (group C), and both two agents in the same manner (group D). The amounts of blood loss, transfusion requirements, frozen fresh plasma (FFP) and overall drainage were assessed. The hemoglobin concentration (Hb), hematocrit and platelet counts were recorded preoperative y, postoperatively and on the first operative day. The coagulation parameters were measured meanwhile. Deep vein thrombosis (DVT) was diagnosed by ultrasound. RESULTS Blood loss of group B and group C decreased similarly by 35.3 and 42.8% (p = 0.212) compared with group A, while group D was reduced by 64.5, 45.1 and 37.8% compared to group A, B and C, respectively. The amount of allogeneic blood transfusion of group B and group C was comparably reduced by 57.6 and 72.4% compared to group A (p = 0.069), while group D decreased by 94.7, 87.5 and 80.9% compared to group A, B and C. Overall drainage of group B, C and D decreased by 23.0, 45.1 and 67.9% compared with group A, respectively, while group C was reduced by 28.7% compared with group B (p < 0.001). The FFP of group B, C and D was reduced by 63.4, 80.2 and 95.0% as compared with group A, while group C decreased by 45.9% as compared to group B (p = 0.025). There were no urgent coagulation disorders or DVT reported. CONCLUSIONS In our study, batroxobin and TXA can markedly reduce the blood loss and the transfusion requirements equivalently. However, TXA performs better in minimizing FFP and the overall drainage than batroxobin. The combination seems to achieve best results and was more effective than either of the two drugs alone. No apparent adverse events were detected in these groups.
