Aspirating TubesCategory: INSTRUMENTARIUM Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery Independent aspirating tubes involve delay in their use as compared to aspirating canals in the wall of the endoscopic tube; but there are special cases in which an independent tube is invaluable. Three forms are used by the author. The velvet eye cannot traumatize the mucosa (Fig. 9). To hold a foreign body by suction, a squarely cut off end is necessary. For use through the tracheotomic wound without a bronchoscope a malleable tube (Fig. 10) is better. [FIG. 9.--The author's protected-aperture endoscopic aspirating tube for aspiration of pharyngeal secretions during direct laryngoscopy and endotracheobronchial secretions at bronchoscopy, also for draining retropharyngeal abscesses. The laryngoscopes are obtainable with drainage canals, but for most purposes the independent aspirating tube shown above is more satisfactory. The tubes are made in 20 30, 40, and 60 cm. lengths. An aperture on both sides prevents drawing in the mucosa. It can be used for insufflation of ether if desired. An aspirating tube of the same design, but having a squarely cut off end, is sometimes useful for removing secretions lying close to a foreign body; for removing papillomata; and even for withdrawing foreign bodies of a soft surface consistency. It is not often that the foreign bodies can be thus withdrawn through the glottis, but closely fitting foreign bodies can at least be withdrawn to a higher level at which ample forceps spaces will permit application of forceps. Such aspirating tubes, however, are not so safe to use as the protected, double aperture tubes.] [FIG. 10.--The author's malleable tracheotomic aspirating tube for removal of secretions, exudates, crusts, etc., from the tracheobronchial tree through the tracheotomic wound without a bronchoscope. The tube is made of copper so that it can be bent to any curve, and the copper wire stylet prevents kinking. The stylet is removed before using the tube for aspiration.] [28] Aspirators.--The various electric aspirators so universally used in throat operations should be utilized to withdraw secretions in the tubes fitted with drainage canals. They, however, have the disadvantages of not being easily transported, and of occasionally being out of order. The hand aspirator shown in Fig. 11 is, therefore, a necessary part of the instrumental equipment. It never fails to work, is portable, and affords both positive and negative pressures. The positive pressure is sometimes useful in clearing the drainage canal of any particles of food, tissue, clots, or secretion which may obstruct it; and it also serves to fill the stomach or esophagus with air when the ballooning procedure is used. The mechanical aspirator (Fig. 12) is highly efficient and is the one used in the Bronchoscopic Clinic. The positive pressure will quickly clear obstructed drainage canals, and may be used while the esophagoscope is in situ, by simply detaching the minus pressure tube and attaching the plus pressure. In the lungs, however, high plus pressures are so dangerous that the pressure valve must be lowered. [Fig. 11--Portable aspirator for endoscopy with additional tube connected with the plus pressure side for use in case of occlusion of the drainage canal. This aspirator has the advantage of great power with portability. Where portability is not required the electrically operated aspirator is better.] [FIG. 12.--Robinson mechanical aspirator adapted for bronchoscopic and esophagoscopic aspiration by the author. The positive pressure is used for clearing obstructed drainage canals and tubes.] [FIG. 13.--Apparatus for insufflation of ether or chloroform during bronchoscopy, for those who may desire to use general anesthesia. The mechanical methods of intratracheal insufflation anesthesia subsequently developed by Meltzer and Auer, Elsberg, Geo. P. Muller and others have rightly superseded this apparatus for all general surgical purposes.] Next: Sponge-pumping Previous: Batteries
