discussion the vigilance and experience of medical personnel in the icu, appropriate iv sedation, and using a bite block are the best ways to prevent mortality caused by aspiration of an ett in all intubated patients. case presentation we report a case of death caused by tracheal tube aspiration, where it was located distal to the vocal cords, with a part of it entering the right bronchus and t...

Recently, endotracheal stenting has become critical in treating respiratory diseases. Due to the COVID-19 pandemic recent years, many patients had stenosis because of long-term intubation, and silicone stents can be used treat tracheal these patients. Standard airway are tubes that provide immediate relief but prone migration. In this work, we design different analyze them trachea evaluate sten...

  Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...

conclusions in this case, after failure of awake fiberoptic intubation, awake direct laryngoscopy and blind nasal intubation, finally awake nasal intubation in sitting position, using fiberoptic led to success. case presentation the present case discusses a patient with severe deformity of mandible that was admitted for correction with free-flap. the following intubation techniques were used fo...

Silicone stents are routinely used for the maintenance of patent mucosal passages in patients with nasolacrimal disorders. A common complication associated with the use of silicone stents is lateral migration or displacement of the tubes, which can be difficult to correct. This report describes a modified Quickert-Dryden approach with fixation of the tubes by an intrasac suture. From 1990 to 19...

AIM: To investigate the feasibility of endoscopic dacryocystorhinostomy (En-DCR) with bicanalicular silicone tube intubation for treating chronic dacryocystitis secondary to nasolacrimal duct stent (NDS) incarceration. METHODS: En-DCRs were performed on 44 patients (46 eyes) NDS incarceration from April 2016 October 2022. The granuloma and scar tissues separated, removal was achieved during sur...

The leading cause of anesthesia-related injury is the inability to intubate the trachea and secure the airway.1 Improvements in video and optical laryngoscopy have allowed to obtain an indirect view of the glottis in a more simple way but sometimes this advantage occurs together with a difficult or impossible endotracheal tube (ETT) insertion.2 This is because indirect techniques do not require...

purpose: to evaluate the efficacy of silicone oil injection after deep vitrectomy in infectious endophthalmitis regarding visual acuity. methods: this single-blind randomized clinical trial was performed on 50 cases of infectious endophthalmitis undergoing deep vitrectomy. patients were randomly assigned to two groups: in one group silicone oil was injected into the eye at the end of the operat...

OBJECTIVE To determine whether prior silicone injection increases the risks associated with carbon dioxide laser resurfacing. DESIGN Laboratory determination of the effect of laser energy on liquid silicone; histologic evaluation of silicone-injected skin after lasing; and histologic demonstration of silicone deposits in all layers of dermis years after injection of silicone as filler fluid. ...

PURPOSE To evaluate surface properties of various intraocular lenses (IOLs), including a newly fabricated heparin-surface-modified (HSM) silicone IOL, with special reference to their efficiency in reducing potential silicone oil adherence to the IOL optics. SETTING Center for Research on Ocular Therapeutics and Biodevices, Department of Ophthalmology, Storm Eye Institute, Medical University o...
