Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 80 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Blood loss is a significant issue in spinal deformity surgery, often requiring allogenic blood transfusion and/or intraoperative blood salvage and leading to increased risk of postoperative morbidity, increased length of stay, and higher total hospital costs. Tranexamic acid is an antifibrinolytic agent that is used in many surgical specialties to prevent perioperative blood loss. Intravenous (ivTXA) dosing has proven effective in reducing blood loss and perioperative transfusion in spinal surgery, while the topical (tTXA) form has been shown to be at least non-inferior to IV transfusion in the total arthroplasty literature. Intravenous TXA is routinely used at the investigators' institution in spinal deformity cases, but even with ivTXA infusion, perioperative blood loss remains a significant issue, with total estimated and calculated blood loss between ~1500-3000 mL. Usage of local tTXA in addition to ivTXA may provide additional benefits including an additive effect on decreasing blood loss, allowing for lowered dosages of ivTXA, decreasing risks associated with systemic exposure. Combination ivTXA and tTXA has shown excellent results in total joint arthroplasty. The objective of this study is to determine the additive benefit and risks of co-administration of the two in spinal deformity surgery. This population of spinal patients was chosen because the estimated blood loss is high and the potential clinical benefit of the intervention is large. Patients will be enrolled if they are undergoing surgery > 5 levels with extension to the pelvis. The investigators have previously utilized topical TXA for these cases by applying operative sponges soaked with solution into the wound during routine x-ray check following instrumentation, with anecdotally good effect. However, this practice has not been prospectively studied. In this prospective, randomized, blinded, placebo controlled study, a similar combined effect of ivTXA and tTXA on decreasing perioperative blood loss as seen in total joint arthroplasty, with a similar safety profile is expected.
Experimental: ivTXA + topical TXA
TXA lavage solution (200 cc sterile normal saline + 5 g tranexamic acid 100mg/ml (50cc)) will be poured into the surgical field and left in contact for five minutes. This will occur after instrumentation. Excess solution will be suctioned away using a non-cell saver suction. IV txa will be given as (5mg/ml) loading dose (20mg/kg) over 15 minutes followed by 2 mg/kg/hr maintenance dosing as per hospital protocol
Placebo Comparator: IV TXA + topical placebo
Placebo solution (200 cc sterile normal saline + placebo TXA ampule (normal saline) (50cc)) will be poured into the surgical field and left in contact for five minutes. This will occur after pedicle screw instrumentation. Excess solution will be suctioned away using a non-cell saver suction. IV txa will be given as (5mg/ml) loading dose (20mg/kg) over 15 minutes followed by 2mg/kg/hr maintenance dosing as per hospital protocol
Drug: - Tranexamic Acid 100 MG/ML
TXA lavage solution (200 cc sterile normal saline + 5 g tranexamic acid 100mg/ml (50cc)) will be poured into the surgical field and left in contact for five minutes. This will occur after instrumentation. Excess solution will be suctioned away using a non-cell saver suction.
Drug: - Placebo
Placebo solution (200 cc sterile normal saline + placebo TXA ampule (50cc)) will be poured into the surgical field and left in contact for five minutes. This will occur after pedicle screw instrumentation. Excess solution will be suctioned away using a non-cell saver suction.
