Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Heart Rate | heart beats for minutes | intraoperative | |
Primary | Estimated Blood Loss | 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 dividing by surgical time in hours. | end of operation assessment | |
Secondary | The Boezaart and van der Merwe intraoperative surgical field scale | Boezaart Bleeding Scale (BBS) (0 - no bleeding (cadaveric conditions), 1 - Slight bleeding, no suctioning required, 2 - Slight bleeding, occasional suctioning required, 3 - Slight bleeding, frequent suctioning required; bleeding threatens surgical field a few seconds after suction is removed, 4 - Moderate bleeding, frequent suctioning required, and bleeding threatens surgical field directly after suction is removed, 5 - Severe bleeding, constant suctioning required; bleeding appears faster than can be removed by suction; surgical field severely threatened and surgery usually not possible). | Every 15 minutes for the duration of surgery | |
Secondary | plasma norepinephrine concentrations | plasma norepinephrine concentrations measured by enzyme immunoassay as venous blood samples about 4ml will be collected from each patient under aseptic condition | baseline before Anastasia ( in the holding area with insertion of I.V. cannula) and three hours after the end of surgery. | |
Secondary | serum cortisol concentrations | serum cortisol will be measured by enzyme immunoassay as venous blood samples about 4ml will be collected from each patient under aseptic condition | baseline before Anastasia ( in the holding area with insertion of I.V. cannula) and three hours after the end of surgery. |
