The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.
FAQs
Atomization breaks a liquid, suspension, or powder feed into fine droplets or particles that can reach the target surface. Spray pressure helps propel this dispersed material through the nozzle, while particle size influences how the coating is distributed. Controlling these variables is therefore important for producing a consistent layer rather than an uneven surface treatment.
The substrate provides the surface to which the deposited material must adhere, so its condition directly affects coating attachment. Surface characteristics should be considered alongside spray pressure and particle size when seeking a uniform result. In engineering components, appropriate substrate preparation supports the intended protective, functional, or decorative performance of the finished coating.
Drying or curing determines how the applied material develops into a stable coating layer after deposition. These stages influence the final uniformity and adhesion of the coating, and therefore affect whether the surface delivers its intended property. Engineers must account for them when applying coatings for corrosion resistance, wear resistance, insulation, appearance, or biocompatibility.
Spray coating can accommodate liquid materials, suspensions, or powders, so the feed form is a major process consideration. Each form must be dispersed and propelled through the nozzle as droplets or particles before reaching the substrate. This flexibility allows engineers to match the coating material and its delivery form to the required surface function and component material.
A basic workflow includes selecting the coating material, considering the substrate condition, dispersing the feed through a nozzle, and controlling spray pressure and particle size during deposition. The applied layer then undergoes drying or curing. These linked steps determine coating uniformity and adhesion, making process control important from surface preparation through final treatment.
The method is useful when a component needs a surface property that differs from the bulk material, such as corrosion resistance, wear resistance, insulation, appearance, or biocompatibility. It can be applied to metals, polymers, ceramics, and composites. Because it can cover complex geometries, engineers can use it across varied component designs and manufacturing needs.
Spray coating supports scalable manufacturing because it can cover complex geometries while accommodating diverse coating materials. The resulting layer can be designed to provide protective, functional, or decorative performance without limiting the approach to one substrate class. Engineers can therefore adapt the method to different component materials and surface requirements while monitoring uniformity and adhesion as key outcomes.
