Anchoring The Foreign Body Against The Tube Mouth
If withdrawal be made a bimanual procedure it is almost certain that the foreign body will trail a centimeter or more beyond the tube mouth, and that the closure of the glottic chink as soon as the distal end of the bronchoscope emerges will strip ... Extraction Of Soft Friable Foreign Bodies From The Tracheobronchial Tree
The difficulties here consist in the liability of crushing or fragmenting the object, and scattering portions into minute bronchi, as well as the problem of disimpaction from a ring of annular edema, with little or no forceps space. There is usually... Extraction Of Tacks Nails And Large Headed Foreign Bodies From The Tracheobronchial Tree
In cases of this sort the point presents the same difficulty and requires solution in the same manner as mentioned in the preceding paragraphs on the extraction of pins. The author's inward-rotation method when executed with the Tucker forceps is id... Inward Rotation Method
When the point is found to be buried in the mucosa, the best and usually successful method is to grasp the pin as near the point as possible with the side-grasping forceps, then with a spiral motion to push the pin downward while rotating the forcep... Mechanical Problems Of Bronchoscopic Foreign Body Extraction*
* For more extensive consideration of mechanical problems than is here possible the reader is referred to the Bibliography, page 311, especially reference numbers 1, 11, 37 and 56. The endoscopic extraction of a foreign body is a mechanical pr... Penetrating Projectiles
Foreign bodies that have penetrated the chest wall and lodged in the lung may be removed by oral bronchoscopy if the intruder is not larger than the lumen of the corresponding main bronchus (see Bibliography, 43) [FIG. 90.--Schematic illustration... Removal Of Double Pointed Tacks
If the tack or staple be small, and lodged in a relatively large trachea a version may be done. That is, the staple may be turned over with the hook or rotation forceps and brought out with the points trailing. With a long staple in a child's trach... Removal Of Foreign Bodies From The Larynx
Symptoms and Diagnosis.--The history of a sudden choking attack followed by impairment of voice, wheezing, and more or less dyspnea can be usually elicited. Laryngeal diphtheria is the condition most frequently thought of when these symptoms are pre... Removal Of Open Safety Pins From The Trachea And Bronchi
Removal of a closed safety pin presents no difficulty if it is grasped at one or the other end. A grasp in the middle produces a toggle and ring action which would prevent extraction. When the safety pin is open with the point downward care must be ... The Extraction Of Tightly Fitting Foreign Bodies From The Bronchi
Annular Edema Such objects as marbles, pebbles, corks, etc., are drawn deeply and with force by the inspiratory blast into the smallest bronchus they can enter. The air distal to the impacted foreign body is soon absorbed, and the negative pressure... The Light Reflex On The Forceps
It is often difficult for the beginner to judge to what depth an instrument has been inserted through the tube. On slowly inserting a forceps through the tube, as the blades come opposite the distal light they will appear brightly illuminated; or s... The Use Of Forceps In Endoscopic Foreign Body Extraction
Two different strengths of forceps are supplied, as will be seen in the list in Chapter 1. The regular forceps have a powerful grasp and are used on dense foreign bodies which require considerable pressure on the object to prevent the forceps from s...
