Controlled Clinical Trial
Preliminary investigation of high-dose tranexamic acid for controlling intraoperative blood loss in patients undergoing spine correction surgery.
With a significant increase in the number and complexity of spinal deformity corrective surgeries, blood loss, often requiring massive intraoperative transfusions, becomes a major limiting factor during surgery. This scenario is particularly during posterior vertebral column resection (PVCR), where extensive intraoperative blood loss may pose a major risk to the patient, preventing smooth execution of the procedure. Tranexamic Acid (TXA) has been used in cardiac and orthopedic surgeries, including major spinal surgeries, to reduce blood loss and transfusion requirements for decades. ⋯ In our study, high doses of TXA have been shown to effectively control blood loss and reduce the transfusion requirement. This effect was more apparent in patients receiving PVCR. No adverse drug reaction was recorded in the study. In the future, prospective randomized controlled trials to validate our results will be necessary. Future studies conducted on older patient cohort may also be necessary to confirm the safety of extending the use of TXA to the older patients.

The North American Spine Society (NASS) publishes clinical guidelines that are taken into consideration worldwide by clinicians who have a special interest in spinal surgery. The Appraisal of Guidelines for Research and Evaluation (AGREE) II is the second version of the original AGREE instrument to assess the quality of guidelines in terms of development process. This appraisal aims to evaluate each individual NASS guideline using AGREE II tool to demonstrate its methodologic robust and weakness. ⋯ Our study showed that the quality of the NASS guidelines needs some improvement. There is a critical need for broader stakeholder involvement including patient representatives and health economists. Consideration of resource implications and monitoring process and standardization of how recommendations are implemented need to be improved. Studies analyzing facilitators and barriers would be helpful for future NASS guidelines.

Spine surgery is usually associated with large amount of blood loss, necessitating blood transfusions. Blood loss-associated morbidity can be because of direct risks, such as hypotension and organ damage, or as a result of blood transfusions. The antifibrinolytic, tranexamic acid (TXA), is a lysine analog that inhibits activation of plasminogen and has shown to be beneficial in reducing surgical blood loss. ⋯ Tranexamic acid reduces surgical bleeding and transfusion requirements in patients undergoing spine surgery. Tranexamic acid does not appear to be associated with an increased incidence of pulmonary embolism, DVT, or MI.

Current evidence suggests that neck pain is negatively associated with health-related quality of life (HRQoL). However, these studies are cross-sectional and do not inform the association between neck pain and future HRQoL. ⋯ We found that neck pain was negatively associated with physical but not mental HRQoL. Our analysis suggests that neck pain may be a contributor of future poor physical HRQoL in the population. Raising awareness of the possible future impact of neck pain on physical HRQoL is important for health-care providers and policy makers with respect to the management of neck pain in populations.

Use of bone morphogenetic protein (BMP) as an adjunct to spinal fusion surgery proliferated after Food and Drug Administration (FDA) approval in 2002. Major safety concerns emerged in 2008. ⋯ Use of BMP in spinal fusion surgery declined subsequent to published safety concerns and revelations of financial conflicts of interest for investigators involved in the pivotal clinical trials.
