The purpose of this study is to compare the blood loss during sinus surgery looking at two different types of anesthesia: either intravenous anesthesia with propofol or inhalational anesthesia with sevoflurane.

Condition Intervention
Blood Loss
Drug: propofol
Drug: sevoflurane

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Comparison of Intraoperative Bleeding During Endoscopic Sinus Surgery Between Patients Receiving Total Intravenous Anesthesia With Propofol and Patients Receiving an Inhalational Anesthetic With Sevoflurane

Further study details as provided by University of Chicago:

Primary Outcome Measures:
  • Estimated Blood Loss [ Time Frame: from the start of surgery to the end of surgery, up to 6 hours ]
    Estimated blood loss in milliliters per hour is calculated by subtracting the volume of total irrigation used during the case from the total amount of fluid in the suction canister at the end of surgery and dividing by surgical time in hours.

Secondary Outcome Measures:
  • Anesthesiologist Numeric Rating Scale (ANRS) [ Time Frame: at the end of surgery (up to 6 hours) ]
    The anesthesiologist numeric rating scale is to rate the ease of the anesthesia technique ranging from 0 to 10 (10 is best, 0 is worst).

  • Surgeon's Numeric Rating Scale (SNRS) [ Time Frame: at the end of surgery (up to 6 hours) ]
    The surgeon's numeric rating scale(SNRS)is to rate the surgical conditions (mucosal bleeding and visibility) on a scale ranging from 0 to 10, with 0 defined as cadaveric conditions and 10 as severe bleeding requiring constant suction.
