简要总结
The goal of this interventional study is to compare the efficacy (surgical field quality and intra-operative blood loss) or cost of TIVA alone to general inhalational anesthetics with intravenous TXA in patient participants who are undergoing endoscopic sinus surgery.
The main questions the study aims to answer are:
- Is the surgical field quality better when using TIVA alone compared to general inhalational anesthetics with intravenous TXA?
- Is one method more financially advantageous to the participant and the institution compared to the other method?
Participants will be randomized into one of the two anesthesia cohorts prior to sinus surgery. One group will be given total intravenous anesthesia (TIVA) alone and the other will be given intravenous tranexamic acid (TXA) followed by general inhalational anesthesia.
Researchers will compare the TIVA group to the TXA group to see if one group exhibits a better surgery field viewing quality through a subjective evaluation and measurement of blood loss and also which anesthesia regimen is most cost effective upon conducting a cost analysis.
详细描述
This study aims to prospectively compare surgical field quality and intraoperative blood loss between patients treated with perioperative intravenous tranexamic acid (TXA) followed by general inhalational anesthesia (sevoflurane, isoflurane, or desflurane) to total intravenous anesthesia (TIVA) alone, which consists of propofol and remifentanil. A secondary objective would be to perform a cost analysis between these two groups to determine whether one method is financially more advantageous than the other.
This study will be a prospective double-blinded randomized control trial consisting of patients undergoing endoscopic sinus surgery to assess intraoperative blood loss, surgical field quality, and cost of the medications administered. The control group will receive total intravenous anesthesia without tranexamic acid during surgery. The study group will receive preoperative tranexamic acid with general inhaled anesthetics during surgery (detailed below). Randomization will be conducted via a pre-determined permuted block system (e.g. AABB, ABAB, BBAA, AABB, etc, where A is TIVA and B is general inhalational anesthetics with preoperative TXA). Subjects who consent to participate will be assigned to the A or B arm depending on whichever arm is listed next in the order.
Subjects will be informed about the study and consented during pre-operative clinic visits. The patient consent and HIPAA authorization forms will be presented at that time where the subject can read about the study followed by any verbal conversation or questions needed between the subject and the study team. This will be done in a private patient room setting. The subject will be notified that participation in the study is completely voluntary and that their medical care will not be affected regardless of their decision to participate. Of note, if patients decline to participate, they will undergo general anesthesia using TIVA without TXA, as this is the standard choice at our institution. Subjects will not receive payment or compensation for their participation.

盲法说明
The operating surgeon will be blinded to the type of anesthesia used by applying a surgical drape between surgeon and patient and anesthesia team. The patient will also not know which anesthesia arm they will be placed in as the randomization will occur prior to surgery and will only be known to the anesthesia team and other study team members who are not operating on the patient.

研究组 & 干预措施
Total Intravenous Anesthesia (TIVA)
Patients will be induced with fentanyl 1-2µg/kg, propofol 2mg/kg, and lidocaine 1mg/kg. After orotracheal intubation, anesthesia will be maintained with propofol 150mg/kg/min, remifentanil 0.05-2µg/kg/min, and rocuronium or succinylcholine as indicated. This is standard of care for this procedure. Within 10 minutes of induction, patients in the control group will be administered a 100mL bolus of normal saline as placebo.
干预措施: Total Intravenous Anesthesia (Drug)
Transexemic Acid (TXA) and Inhalational Anesthesia
Patients will be induced with fentanyl 1-2µg/kg, propofol 2mg/kg, lidocaine 1mg/kg. After orotracheal intubation, anesthesia will be maintained with isoflurane 1.5-2% or sevoflurane 1-2%, as well as rocuronium or succinylcholine as indicated. Again standard of care procedure is applied. Within 10 minutes of induction, patients in the study group will be administered 15mg/kg TXA suspended in 100mL of normal saline intravenously.
干预措施: Tranexamic acid injection (Drug)
Transexemic Acid (TXA) and Inhalational Anesthesia
