Trial Outcomes & Findings for Intraoperative Bleeding During Endoscopic Sinus Surgery (NCT NCT01014728)

NCT ID: NCT01014728

Last Updated: 2014-02-14

Results Overview

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.

Measure
Intravenous Anesthesia
After induction, the intravenous anesthesia group received an infusion of propofol (100-200 μg/kg/min) for endoscopic sinus surgery.
Inhalation Anesthesia
After induction, the inhalation anesthesia group received sevoflurane (1% to 3%) for endoscopic sinus surgery.

SECONDARY outcome

Timeframe: at the end of surgery (up to 6 hours)

Population: There were three patients in the inhalation anesthesia group with missing values.

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).

SECONDARY outcome

Timeframe: at the end of surgery (up to 6 hours)

Population: There were three patients in the inhalation anesthesia group with missing values.

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.
