Assessing the Efficacy of Photodynamic Therapy for Preventing Surgical Site Infections

This is a randomised, unblinded interventional device proof of concept pilot trial in which patients undergoing nasal surgery will be selected for either photodisinfection therapy (PDT) with the Steriwave™ ND System, or control with nares swabbed with 'photosensitizer formulation' preoperatively. This trial will primarily assess the safety and efficacy of nasal photodisinfection treatment in decreasing post-operative events in patients undergoing nasal surgery. After signing informed consent, and before surgery, participants will receive a baseline culture of the anterior nares to determine nasal bacterial colonization and will have a flexible nasendoscopy to determine their Lund-Kennedy (LK) endoscopic score. Subjects will then be randomised to nasal PDT (which includes two applications of 'photosensitizer formulation' \[0.01% methylene blue with 0.25% chlorhexidine solution\], two minutes apart), along with light therapy, or control with nares swabbed twice with 'photosensitizer formulation' with two minutes in between (no light therapy). Following treatment, participants will be re-cultured (2 weeks after the surgery ± 7 days) and reviewed for antibiotic use and surgical site infection (SSI) using LK endoscopic scoring. At 30 days, all participants will be followed up by telephone to review if they received antibiotics for presumed postoperative infection. Standard post-operative care will be provided according to the type of surgery performed. Any required interventions post-operatively will be documented.

Dexmedetomidine and Agitation After Nasal Surgery

The main objective of study is to compare dexmedetomidine single bolus dose before extubation with continuous infusion as regards their efficacy in mitigating the incidence of emergence agitation in obese adults undergoing nasal surgery.

Comparison of Remimazolam and Propofol for Recovery of Ambulatory Upper Airway Surgery

The purpose of this study is to compare the effects of remimazolam and propofol on postoperative recovery time, complications, and safety in patients undergoing ambulatory upper airway surgery under general anesthesia.

Study on the Efficacy and Safety of a Device for Post-op Recovery in Pediatric Adenectomy/Adenotonsillectomy.

The objective of this prospective pre-market interventional clinical study is to evaluate the efficacy and safety of the medical device Munatoril® Aerosol Combo in its different modalities of use, through the analysis of clinical and subjective outcomes in children operated on adenoidectomy or adenotonsillectomy, compared with a hypertonic solution and an over-the-counter isotonic solution (control group). The primary question it aims to answer is whether the components prensent in Munatoril provide a benefit and whether they play a role in the recovery of nasal homeostasis following adeinodectomy and adenotonsillectomy compared with an over-the-counter hypertonic saline solution. Endpoints Evaluation of subjective longitudinal differences (intragroup over-time change) and differences between study group and control group (intergroup difference) regarding the use of the medical device, obtained following the protocol, with assessment at 8, 15 and 30 days after surgery by Likert Scale Score for tolerability, and at 0, 15 and 30 days by SNOT22 Score and Lund-Kennedy Endoscopic Score for efficacy. In addition, there is a recording of any adverse events in both groups at 8, 15 and 30 days post-surgery, and an inter-group comparative evaluation. Participants: Pediatric patients who are candidates for adenoidectomy or adenotonsillectomy surgery at the study site facility will be systematically evaluated preoperatively for inclusion in the clinical trial and possibly recruited. Follow-up will last 30 days.

Collection of Primary Human

Treatment and prevention of respiratory infections are of great interest in many medical areas. Create a physical device covered by primary human nasal cells could be very usefull in order to analyse delivery and efficiency of drugs. In this context the aim of this project is to create a collection of primary cells from the human nasal epithelium. This collection will be realised during programmed surgery, thanks to a specific device dedicated to collect nasal cells. Then the cells will be sent to the lab in order to grow at the air-liquid interface, which is an excellent 'ex vivo' model for their study.
