Background: Control of bleeding is very important during endoscopic sinus surgery. Saline heated up to 50 °C causes dilatation of vessels and edema without nasal mucosa necrosis. It also promotes the clotting cascade so helps in having a bloodless procedure.
Methods and materials: This randomized controlled trial was conducted on 60 patients divided into two groups (30 each). Group A was the interventional group in which patients were irrigated with saline of 50 °C during surgery. Group B was the control group where room-temperature saline was used. The operative field was assessed using the Boezaart score, duration of surgery, and bleeding in ml.
Results: The Boezaart score in group A came out to be 2.23 ± 0.72 whereas it was 3.43 ± 0.72 in group B. Most of the patients who were in the interventional group had their surgery completed within 60 min with comparatively less bleeding (mean bleeding = 221.83 ml). Patients of the control group had increased duration of surgery mostly and bleeding (mean = 265.67 ml). Our study showed a strong correlation amongst the Boezaart score, duration of surgery, and bleeding in ml with a p value of < 0.001 where all three variables significantly improved in the interventional group due to a good operative field provided by warm saline heated up to 50 °C.
Conclusion: Normal saline heated up to 50 °C is a cost-effective way to achieve a bloodless operative field during endoscopic sinus surgery. Reduced bleeding also decreases the duration of surgery.
