Does The Combined Use Of Local And Intravenous Tranexamic Acid Offer Better Surgical Field Quality...

Chronic Sinus DiseaseNasal Polyps

Functional Endoscopic Sinus surgery (FESS) is a surgery done for chronic rhinosinusitis after failure of medical treatment. Intraoperative bleeding poses a challenge to both the surgeon and anaesthetist. Although blood loss is not massive during FESS, bleeding may obscure the surgical field prolonging the time of surgery or even leading to incompletion of the surgery. Different methods have been used to improve the surgical field but none without side effects. The use of diathermy carries the risk of local tissue damage with the risk of subsequent bleeding. Local vasoconstrictors carry the risk of systemic absorption. Induced hypotension may not be suitable for all patients; besides, this may necessitates the use of more anaestheic drugs with their associated side effects. In addition, none of theses methods have provided ideal surgical field for the surgeon.1-3 Tranexamic acid, an antifibrinolytic agent, has been used to decrease surgical field bleeding in different surgeries showing effectiveness in its topical, oral and intravenous use.4-6 The aim of this study is to evaluate the effectiveness of local, intravenous and combined use of tranexamic acid in improving the surgical field quality during functional endoscopic sinus surgery.

The Effects of Steroid-eluting Stent Implant for the Treatment of Eosinophilic Chronic Rhinosinusitis...

PatientsSinusitis1 more

The treatment of eosinophilic sinusitis with nasal polyps is difficult and challenging. After endoscopic sinus surgery(ESS), complications such as edema, scar formation, adhesions, sinus stenosis and recurrence of polyps are prone to occur. Investigators aim to assess the efficacy and safety of Steroid-eluting stent when implanted in sinus in patients following ESS with eosinophilic sinusitis and nasal polyps.The randomized, double-blind, controlled clinical trial enrolled patients with eosinophilic sinusitis and nasal polyps. After endoscopic bilateral sinus surgery, the Steroid-eluting stents were randomly implanted in one side of the sinus and the other side as a control. Primary outcomes are change in the Lund-Kennedy endoscopic score.The primary outcomes will be measured in baseline, week4,week 8 and week 12. Secondary outcomes include the changes in symptoms measured by Visual analog score and nasal patency (nasal airway resistance and nasal cavity volume), exhaled nasal nitric oxide. The investigators also evaluate change in inflammatory cytokines (interleukin(IL)-4, IL-5, IL-8, IL-17, IL-22, IL-25, interferon-γ, tumor necrosis factor-α, transforming growth factor-β, Leukotriene,Eotaxin) in nasal secretions. The secondary outcomes will be measured in baseline, week4, week8 and week12. Mucosal pathology assessment will be performed at 4 weeks postoperatively.Sinus CT scan will be conducted at 8 weeks after surgery. Changes in serum cortisol are monitored at baseline,week4 and week12 postoperatively. All adverse events are recorded throughout the experiment

Comparing Budesonide Via MAD or INSI Prospective Cohort Study

Chronic Rhinosinusitis With Nasal PolypsAllergic Fungal Sinusitis

Chronic Rhinosinusitis (CRS) is a common disorder in North America, affecting more than 31 million people annually. Common therapy for CRS includes intranasal corticosteroids (INCS) such as budesonide. At our centre , the current practice is to administer budesonide two ways: the mucosal atomization device (MAD), which is a nasal spray or impregnated budesonide in nasal saline irrigation (INSI), which is a nasal rinse. Our study aims to see which method of administering budesonide has the best treatment outcomes after sinus surgery. This study will follow patients over a six-month period of time.

Anterior Ethmoidal Nerve Block in Prevention of Postoperative Agitation

Postoperative Agitation: Impaired AwarenessAbnormal Cognitive Function5 more

Postoperative agitation is an important complication of general anesthesia, moreover, it has been found with high incidence in ear, nose, throat (ENT) surgeries. We aim to study whether anterior ethmoidal nerve block will be successful in reducing postoperative agitation in those patients. Study population will be randomized into two groups, treatment and control group. Anterior ethmoidal nerve block will be done in treatment group and postoperative agitation compared between these two groups. Agitation score will be scored with Riker Sedation-Agitation Scale (SAS). Ho: Occurrence of post-operative agitation in patients undergoing nasal surgery with nasal pack under general anesthesia is equal in those with ethmoidal nerve block as compared to those without the block. Ha: Occurrence of post-operative agitation in patients undergoing nasal surgery with nasal pack under general anesthesia is not equal in those with ethmoidal nerve block as compared to those without the block.

Genetics and Genomics of Aspirin Exacerbated Respiratory Disease (AERD)

Aspirin Exacerbated Respiratory DiseaseAspirin-Sensitive Asthma1 more

Aspirin Exacerbated Respiratory Disease (AERD) is a relatively homogeneous disease characterized by adult-onset severe asthma, development of non-cancerous growths in the nasal canal (i.e. nasal polyps) and aspirin allergy. The cause of AERD is unknown, although likely results from environmental insults in combination with genetic susceptibility. AERD disease homogeneity increases the possibility of discovering narrowly-defined genetic contributors, and makes it an ideal population to study the genetic and epigenetic changes that cause asthma. Researchers recently discovered that gene expression of epithelial growth and repair (EGR) genes are substantially decreased in bronchial airway epithelial cells of severe asthmatics compared to less severe asthmatics and healthy controls. This new finding indicates that epithelial integrity and related processes may be of primary importance to the development of severe asthma, and potentially the severe asthma subtype, AERD. This finding was later supported in a subsequent lab model, which showed that blocking a central epithelial repair and differentiation gene, human epidermal growth factor receptor 2 (ERBB2), decreased healing time of bronchial epithelial cells after injury. Thus, the objective of the proposed study is to determine whether EGR gene are also down-regulated in AERD, a homogeneous severe asthma subtype. As an extension, the researchers will also determine whether genetic mutations and/or epigenetic changes relate to and potentially explain this down-regulation of EGR genes. Specifically, the researchers plan to obtain gene expression of freshly brushed nasal airway epithelial cells of 140 AERD patients, 70 non-aspirin sensitive asthma patients, and 35 healthy controls, noting that nasal epithelial gene expression has recently been shown to mirror lung epithelial changes in asthmatic airways. Swabbing the nasal canal for epithelial cells allows to evaluate airway epithelial cell gene expression non-invasively. Our experimental design contrasts AERD gene expression profiles against healthy controls, and determines whether EGR genes are depressed in AERD relative to health controls. As a corollary, the researchers look to discover an AERD-specific gene expression profile which may one-day aid in diagnosis and expand current knowledge of disease mechanisms. As an extension, the researchers will correlate gene expression changes, specifically any finding of down-regulated EGR genes, with methylation changes (i.e. epigenetic changes) and genetic mutations.

Study of the Efficacy of Topical Nasal Steroids Patients With Nasal Polyps

Size of Nasal PolypsControl of Symptoms

Topical nasal steroid sprays are the mainstream treatment for patients with nasal polyps. Polyps tend to recur after surgery and topical nasal steroid sprays are used as the primary medical management to prevent continued growth. More recently high dose topical nasal steroid sprays are used. It is thought that the higher dose will penetrate the sinus cavities at an increased dose and will allow for greater control of polyp growth. Safety studies have been performed which have shown no suppression of the pituitary axis with long term high dose topical steroid or changes in intraocular pressure. However, studies in efficacy are limited despite their widespread use. The objective of this study will be to compare the effectiveness of two topical nasal steroid sprays in patients with recurrent nasal polyps.
