Filter by:The current study proposes to investigate Point of Care Testing (POCT) (Coagcheck®) and compare obtained results versus standard laboratory coagulation parameters prothrombin time (PT) and partial thromboplastin time (PTT). The time difference in obtaining the two results will also be examined. A total of 100 pediatric patients undergoing spinal surgery will be enrolled and consented per protocol. Blood samples will be obtained simultaneously tested on both the standard laboratory apparatus and the Coagcheck® device. If the two results are comparable, this could have immediate clinical application and impact in the operating room as POCT results are available within 2-3 minutes compared to 1-2 hours for standard laboratory samples.
This is a retrospective chart review of patients undergoing spinal fusion surgery to see the prevalence of hyperventilation.
Current evidence regarding the efficacy and safety of perioperative administration of tranexamic acid for antifibrinolysis does not suffice to support its use in major spinal surgery. OBJECTIVES: To evaluate the effectiveness of tranexamic acid for decreasing transfusion requirements and bleeding in this patient population. To evaluate the safety of this antifibrinolytic agent in the intraoperative and mid-term postoperative period. METHODS: Multicenter, randomized, double-blind, placebo-controlled clinical trial with parallel groups. The main outcome measure is intraoperative and postoperative transfusion requirements; blood loss and safety will also be evaluated. Previous results in other types of surgery suggest that tranexamic acid reduces transfusion requirements and blood loss. Hence, the hypothesis of this study is that tranexamic acid will significantly reduce blood loss in comparison to a placebo in major spine surgery.
Spine fusion is an involved procedure during which patients are at risk for significant intra-operative blood loss.This study will compare 2 ways of determining fluid status and response to fluid administration. One way is to measure the changes in the arterial wave form from the special IV that is usually placed in an artery (PPV). The second way is to use a non-invasive method of a finger probe that measures changes in the plethysmogram or the pleth variability index (PVI). No actual patient treatments will be based on these values during surgery.
The main aim is to evaluate the long-term safety and bone healing in the operated area and to compare bioactive glass granules with autogenous bone as a filler material.
This study plans to learn more about preventing pain in children who are having posterior spinal fusion surgery using two different kinds of morphine (a pain medicine). Also, this study plans to learn about individual differences in the how the different kinds of morphine work in children. Subjects are being asked to be in this research study because they are having spinal fusion surgery, will have pain some of the time and will be getting morphine during and after surgery to help control their pain.
Total intravenous anesthesia(TIVA) is a commonly used anesthetic technique. Although TIVA can be accomplished with a variety of drug combinations, infusions of Propofol and Remifentanil are often used with dosage adjusted manually by the anesthesia provider.The pharmacokinetics of these drugs are well understood, and that knowledge has led to the development of computer controlled infusion pumps that can administer the drugs based upon pharmacokinetic models. Computer controlled infusion schemes automatically adjust the drug administration based upon pharmacokinetic models which typically dictate a tapering infusion scheme. When one considers the dosage of a computer controlled infusion it is obvious that manually imitating a similar scheme may be difficult.This study will evaluate manually controlled infusion schemes using the models built into the Applied Medical Visualizations (Medvis) display and compare the manual dosage schemes to the predicted effect site concentrations and pharmacodynamic effect.
Twelve subjects will be sought for this study. Six subjects will receive the DYNESYS system and six subjects will receive a posterior lumbar interbody fusion (PLIF) with the Silhouette device. All subjects will already be participating in the DYNESYS multi-center study (under IRB #4884) and will have been randomized to either group. Five tantalum beads will be inserted into each vertebra associated with the DYNESYS or fusion surgery. Subjects will be followed in conjunction with the multi-center follow-up schedule and will have RSA exams at the following time points after surgery: 3, 6, 12, 18, and 24 months. Standing neutral, flexion, extension, and lateral bending films will be collected at each time point and the amount of motion in each direction of the "marked" vertebrae will be measured. The time points have been selected based on their clinical relevance for comparison against the standard of care, which is the fusion procedure. Depending on the initial tension of the annular fibers, it is possible the DYNESYS will exhibit more motion with time. The time points are important to track the potential changes.
Radiostereometric Analysis (RSA) is a new imaging technique used to measure motions in the spine. It provides more accurate measurements that could help in diagnosing problems in the spine earlier than standard xray techniques.
This trial is conducted in the United States of America (USA). The purpose of this clinical research trial is to understand how safe and effective Recombinant Activated FVII is for reducing bleeding and blood transfusions in patients undergoing spinal fusion surgery.
