The aim of the study was to investigate whether orally administered steroids might improve surgical field conditions during functional endoscopic sinus surgery.
Total blood loss and visualization of the surgical field during the surgical procedure were compared in 2 groups of 18 patients each with severe nasal polyposis. The groups were similar in respect to age, body mass index, general health status, incidence of allergy, bronchial asthma, aspirin triad, and stage of disease. One group received 30 mg of prednisone daily for 5 consecutive days before the operation. The second group served as a control.
Although the total blood loss was only slightly less in the steroid group, the visual conditions of the surgical field improved significantly.
Better surgical field conditions were the results of the powerful anti-inflammatory and antiedematous activity of the drug, which facilitated blood and secretion evacuation from the operated area and prevented the optic system from staining.

    • "Pre-operative steroid administration in cases of severe nasal polyposis improves visibility due to its anti-inflammatory and anti-edematous effect.[11] Topical vasoconstrictors are applied to decrease blood loss and mucosal congestion, but hypertension and tachycardia may occur,[12] controlled hypotension is commonly used to achieve blood less operative field.[13] "

    ABSTRACT: This study was conducted to evaluate the effect of tranexamic acid (TA) on the intra-operative bleeding during the functional endoscopic sinus surgery (FESS) in children. A total of 100 children recruited to undergo FESS were randomized into two groups. Group I: Was given just after induction, intra-venous 25 mg/kg TA diluted in 10 ml of normal saline. Group II: Was given 10 ml of normal saline. Non-invasive blood pressure, heart rate, and quality of the surgical field were estimated every 15 min. Volume of bleeding and duration of the surgical procedure were recorded. Surgical field quality after 15 min revealed that seven patients in group I had minimal bleeding versus no one in group II, P=0.006. Meanwhile, 35 patients in group I had mild bleeding versus 26 patients in group II, P=0.064. Higher number of patients in group II than in group I had moderate bleeding, P=0006. Also, at 30 min, revealed that 10 patients in group I had minimal bleeding versus one patient in group II, P=0.004. Meanwhile, 37 patients in group I had mild bleeding versus 28 patients in group II, P=0.059. Higher number of patients in group II than in group I had moderate bleeding, P<0001. Duration of the surgeries and volume of bleeding were significantly less in tranexamic group than the placebo group, P<0.0001. Single intra-venous bolus dose of tranexamic in children during the FESS improves quality of surgical field, reduces intra-operative bleeding, and duration of surgery.

    ABSTRACT: Glucocorticoids (GC) are the drugs of choice for the clinical treatment of nasal polyposis, according to the medical literature. Its mechanism of action in the regression of clinical symptoms and polyps, however, is not fully understood. The topical and/or systemic use of glucocorticoids lead to variable expression of cytokines, chemokines and lymphokines, as well as changes in cells. It is known that GC suppresses the expression of pro-inflammatory cytokines, chemokines and adhesion molecules such as ICAM-1 and E-selectin; GC also stimulate the transcription of anti-inflammatory cytokines such as TGF-b. GC suppress pro-fibrotic cytokines related to polyp growth, such as IL-11, the basic fibroblast growth factor (b-FGF), and the vascular endotelial growth factor (VEGF). The action of GC depends fundamentally on their interaction with receptors (GR); certain subjects have a degree of resistance to its effect, which appears to be related with the presence of a b isoform of GR. GC also act variably on the genes involved in immunoglobulin production, presentation, and antigen processing. AIM: We present a review of the literature on the mechanisms of GC action in nasal polyosis. CONCLUSION: Understanding the mechanism of action of GC in nasal polyposis will aid in the development of new, more efficient, drugs.
