Hot Saline Irrigation Study (HSI)
Many methods have been used to reduce bleeding during sinus surgery (FESS) in order to allow for the best surgical view and to reduce risk while in surgery.
Warm irrigation fluid is believed to accelerate the clotting mechanism in the human body. The investigators would like to determine if hot saline irrigation (HSI) compared to room temperature saline irrigation (RTSI) can control bleeding during FESS.
The hypothesis is that HSI is more effective than RTSI in reducing intraoperative bleeding during FESS.

|Official Title:||Hot Saline Irrigation vs Room Temperature Saline Irrigation in the Control of Intraoperative Bleeding During Functional Endoscopic Sinus Surgery (FESS)|
- The Boezaart and van der Merwe intraoperative surgical field scale [ Time Frame: Every 15 minutes for the duration of surgery.. ] [ Designated as safety issue: No ]The Boezaart intra-operative surgical field scale will be used to grade the level of bleeding during surgery. This 0 to 5-point scale will be used to outline the amount of suction required to rid the area of blood disrupting vision. A score of 0 is given for an area with no bleeding, 1 for slight bleeding with no suction required, 2 for slight bleeding requiring suction, 3 for moderate bleeding which improves for several seconds once suction has occurred, 4 for moderate bleeding which restarts directly after suctioning and 5 for severe bleeding which occurs faster then can be removed
- Total Estimated Blood Loss [ Time Frame: Duration of surgery ] [ Designated as safety issue: No ]Total blood loss will be recorded over the duration of surgery.

Experimental: Hot saline irrigation
Hot saline is prepared by first placing 2 litres of sterile normal saline (0.9%) into a basin (IntraTemp Therma BasinTM) that is wrapped in a sterile disposable drape (IntraTemp Therma Basin DrapeTM). The basin is then placed in a medical grade warmer (IntraTemp Fluid Warming SystemTM). The warmer is set to heat the saline up to a temperature of 50 degrees Celsius. An external digital thermometer is placed in the saline at all times to ensure that the temperature is between 45-50 degrees.
Procedure: Hot saline irrigation
The surgical field is flushed with 20 cc of hot saline (45-50 degrees Celsius) at five minutes intervals. This is in contrast to the standard of care, room temperature (20-25 degrees Celsius) saline irrigation.
Other Name: HSI
No Intervention: Room temperature saline irrigation
Room temperature saline is prepared in the same manner as the experimental arm except that the warmer is switched off and the temperature of the saline in the basin is left to equilibrate to the temperature of the operating room.
