Objective To prepare a self-made compound, hemostatic jelly with polylactic acid(PLA), which has the hemostatic and absorbable effect on injured cancellous bone. Methods Two bone defects of 5 mm in diameter and 4 mm in depth were subjected on 20 health rabbits by drilling through their either outside plate of the iliac, and were filled with hemostatic jelly(group A), bone wax(group B) and blank(group C) respectively. Hemostasis were observed and recorded after 1 and 10 minutes. Five specimens were harvested at 2, 4, 8 and 12 weeks postoperatively for histological observation. Results ① Hemostatic effect: Bleeding of injured spongy bone stopped within 10 minutes after the treatment of hemostatic jelly and bone wax, but bleeding of balnk did not stop. Hemostatic jelly and bone wax adhered to bone defects firmly within 10 minutes was after the treatment. ② Absorbable effect: Hemostatic jelly and bone defects have not changed visibly in the first 2 weeks. With histological observation 4 to 8 weeks after the operation, hemastatic jelly was absorbed gradually and replaced by osteogenous tissue. It was absorbed completely after 8 to 12 weeks. Bone wax was not absorbed after 12 weeks, no new bone tissue was observed at bone wax area. The blank was replaced by connective tissue and osteogenous tissue partially after 12 weeks. Conclusion The compound hemostatic jelly manifests both hemostatic and absorbable effects on injured cancellous bone and may substitute for bone wax in clinical application.
Objective To investigate the effectiveness in the treatment of single segment thoracic vertebra tuberculosis by limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation. Methods Between September 2005 and March 2010, 90 cases of single segment thoracic vertebra tuberculosis were treated by using limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation in 44 patients (treatment group) and by one-stage posterior approach, bone fusion, and internal fixation in 46 patients (control group). There was no significant difference in gender, age, disease duration, affected segment, Cobb angle, Frankle grade, erythrocyte sedimentation rate (ESR), and Oswestry disability index (ODI) between 2 groups (P gt; 0.05). Results All incisions healed by first intension. All 90 cases were followed up 24-44 months (mean, 38 months). There was no significant difference in ESR between 2 groups at 1 week and 3 months after operation (P gt; 0.05). Postoperative iconography indicated that the bone fusion rate of the treatment group was 100% and no epidural cicatricial tissue or failure of internal fixation was observed, showing significant difference when compared with control group (3 cases having failure of internal fixation) (P=0.032). The Cobb angles were significantly corrected after operation when compared with preoperative angles in 2 groups (P lt; 0.05). At 2 years after operation and at last follow-up, the Cobb angle and correction loss in treatment group were significantly better than those in control group (P lt; 0.05). The ODI and Frankel grade were significantly improved at last follow-up when compared with preoperative ones in 2 groups (P lt; 0.05); the treatment group was significantly better than the control group in the ODI, improvement rate of ODI (P lt; 0.05), and in Frankel grade (Uc=4.368, P=0.000). Conclusion Compared with conventional operation method, it is an ideal operation method to use limited decompression combined with epidural absorbable haemostat covering and vertebral plate reconstruction based on one-stage posterior approach, debridement, bone fusion, and internal fixation for treatment of single segment thoracic vertebra tuberculosis, with minimal wound, less complications, and good function recovery.
ObjectiveTo systematically review the hemostatic effect of traditional class Ⅲ hemostatic powder and aggregate absorbable hemostat in surgeries. MethodsThe PubMed, Embase, CENTRAL, CNKI, VIP and WanFang Data databases were electronically searched to collect controlled studies related to the objectives from inception to September 18th, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. ResultsA total of 7 randomized controlled trials, 5 cohort studies and 9 animal experiments were included. The results of analysis showed that the group with traditional class Ⅲ hemostatic powder or aggregate absorbable hemostat had a higher hemostatic success rate and shorter hemostatic time than those with no hemostatic material in animal surgeries. And the group with aggregate absorbable hemostat had a higher 10 min hemostatic success rate than those with traditional hemostatic measures. The application of traditional class Ⅲ hemostatic powder in human cardiothoracic surgeries shortened the hemostatic time and reduced drainage after surgeries, but caused more blood loss during knee arthroplasties. Aggregate absorbable hemostat caused less blood loss than traditional hemostatic measures in human hip arthroplasties, and the 5 min and 10 min success rates of aggregate absorbable hemostat group were not worse than those of hemostatic gauze. ConclusionCurrent evidence shows that the hemostatic effect of both traditional class Ⅲ hemostatic powder and aggregate absorbable hemostat are better than that of no hemostatic material in animal and human surgery, but the comparison results between the two and with other hemostatic measures are still not clear. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo review trauma-induced coagulopathy and use of tranexamic acid in patients with traumatic hemorrhage. MethodsThe relevant literatures about the definition and pathogenesis of trauma-induced coagulopathy, and the use of tranexamic acid in patients with traumatic hemorrhage were reviewed. ResultsTraumatic-induced coagulopathy was a coagulation disorder in the early stage after injury, which was associated with the anticoagu-lation and increasing activity of fibrinolysis. Tranexamic acid as an anti-fibrinolytic drug, it had a good result in clinical application, which could reduce the mortality due to bleeding in use within 3 h after injury, the effect was the best in use within 1 h after injury, but it had no benefit or even would increase the mortality due to hemorrhage in use >3 h after injury. There was no standardized dosage of tranexamic acid, but the volumes of blood loss and blood transfusion had no difference under the different dosages. However, high dosage or long-term use of tranexamic acid might increase the risk of the thrombosis or epilepsy. ConclusionEmergency traumatic patients face a series of death threats related trauma. Appropriate and timely hemostasis is important for prognosis. Early, short-term, and appropriate dosage of tranexamic acid could obviously reduce mortality and adverse events, but its timing and dosages need to be further optimized.
Objective To investigate the hemostasis of thermosensitive chitosan hemostatic film. Methods Fifty adult Sprague Dawley rats, male or female and weighing 190-210 g, were made the models of liver injury. The models were randomly divided into 5 groups (n=10) depending on different hemostatic materials. The incision of the liver was covered with the hemostatic materials of 2.0 cm × 1.0 cm × 0.5 cm in size: thermosensitive chitosan hemostatic film (group A), chitosan hemostatic film (group B), cellulose hemostatic cotton (group C), gelatin sponge (group D), and no treatment (group E), respectively. The bleeding time and bleeding amount were recorded. After 4 weeks, the incisions of the liver were observed with HE staining. Results Gross observation showed better hemostatic effect and faster hemostatic time in groups A, B, and C; group D had weaker hemostatic effect and slower hemostatic time; group E had no hemostatic effect. The bleeding time and bleeding amount of groups A, B, C, and D were significantly lower than those of group E (P lt; 0.05). The bleeding time and bleeding amount of groups A, B, and C were significantly lower than those of group D (P lt; 0.05), but no significant difference was found among groups A, B, and C (P gt; 0.05). The liver cells of group A had milder edema and ballooning degeneration than other 4 groups through histological observation. Conclusion The thermosensitive chitosan hemostatic film has good hemostasis effect on the liver incision of rats.

ObjectiveTo investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique.MethodsBetween July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction.ResultsThe operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant (P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension.ConclusionUsing WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient’s own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.
