All foreign body cases should be watched day and night by special nurses until all danger of complications is passed. Complications are rare after careful work, but if they do occur, they may require immediate attention. This applies especially to the subglottic edema associated with arachidic bronchitis in children under 2 years of age. _General Reaction_.--There is usually no elevation in temperature following a short bronchoscopy for the removal of a recently lodged metallic foreign body. If, however, an inflammatory condition of the bronchi existed previous to the bronchoscopy, as for instance the intense diffuse, purulent laryngotracheobronchitis associated with the aspiration of nut kernels, or in the presence of pulmonary abscess from long retained foreign bodies, a moderate temporary rise of temperature may be expected. These cases almost always have had irregular fever before bronchoscopy. Disturbance of the epithelium in the presence of pus without abscess usually permits enough absorption to elevate the temperature slightly for a few days. _Surgical shock_ in its true form has never followed a carefully performed and time-limited bronchoscopy. Severe fatigue resulting in deep sleep may be seen in children after prolonged work. _Local reaction_ is ordinarily noted by slight laryngeal congestion causing some hoarseness and disappearing in a few days. If dyspnea occur it is usually due to (1) Drowning of the patient in his own secretions. (2) Subglottic edema. (3) Laryngeal edema. _Drowning of the Patient in His Own Secretions_.--The accumulation of secretions in the bronchi due to faulty bechic powers and seen most frequently in children, is quickly relievable by bronchoscopic sponge-pumping or aspiration through the tracheotomic wound, in cases in which the tracheotomy may be deemed necessary. In other cases, the aspirating bronchoscope with side drainage canal (Fig. 1, E) may be used through the larynx. Frequent peroral passage of the bronchoscope for this purpose is contraindicated only in case of children under 3 years of age, because of the likelihood of provoking subglottic edema. In such cases instead of inserting a bronchoscope the aspirating tube (Fig. 9) should be inserted through the direct laryngoscope, or a low tracheotomy should be done. _Supraglottic edema_ is rarely responsible for dyspnea except when associated with advanced nephritis.
