Presentation Transcript

Welcome…. : 


Foreign bodies : 

Foreign bodies Types- inorganic or organic.  Inorganic materials -plastic or metal eg; beads and small parts from toys.   Organic foreign bodies, including food, rubber, wood, and sponge, - more irritating to the nasal mucosa and thus may produce earlier symptoms.

Etiology: : 

Etiology: They lack molars for proper grinding of food. They tend to be running or playing at the time of aspiration. They tend to put objects in their mouth more frequently. They lack coordination of swallowing and glottis closure. Curiosity, boredom

Dignosis : 

Dignosis History ABG analysis Chest radiography CT scanning Fluoroscopy Barium or Gastrografin swallow

Foreign bodies in the ear: : 

Foreign bodies in the ear:

Clinical features : 

Clinical features May be asymptomatic Some may cause pain in the ear, redness, or drainage. Hearing may be affected if the object is blocking the ear canal.

Treatment: : 

Treatment: Emergency department care Patients in extreme distress secondary to an insect in the ear require prompt attention. The insect should be killed prior to removal, using mineral oil or lidocaine (2%).

Treatment: : 

Treatment: Methods of removal Irrigation tympanic membrane intact Irrigation with water is contraindicated - soft objects, organic matter, or seeds Suction  Suction the ear with a small catheter held in contact with the object. Avoid any interventions that push the object in deeper.

Nasal foreign bodies (NFBs) : 

Nasal foreign bodies (NFBs)

Pathophysiology : 

Pathophysiology Damage to the nasal cavity and surrounding structures.  They can produce local inflammation, which may result in a pressure necrosis.  Mucosal ulceration and erosion into blood vessels producing epistaxis.  Obstruction to sinus drainage  Secondary sinusitis.Firmly impacted and unrecognized foreign bodies can in time become coated with calcium, magnesium, phosphate, or carbonate and become a rhinolith.

Clinical features: : 

Clinical features: Unilateral nasal discharge. Nasal irritation, epistaxis, sneezing, snoring, sinusitis, stridor, wheezing, or fever.  Unusual patient presentations, such as irritability, halitosis, or generalized bromhidrosis (body malodor).

The physical examination - : 

The physical examination - otorhinolaryngologic examination. Sedation is often helpful in the pediatric population. positioning children younger than 5 years in a supine lying position and older children in a sitting "sniffing" position to allow optimal visualization.  A nasal speculum may also help to view the nasal cavity.

Planning/Pretreatment : 

Planning/Pretreatment Careful planning Necessary instruments at the bedside Emergency airway supplies - readily available - foreign body results in aspiration. Pharmacological vasoconstriction of the nasal mucosa can facilitate both examination and removal of a NFB. - 1% lidocaine

Specific Removal Techniques : 

Specific Removal Techniques For easily visualized nonspherical and nonfriable objects, - direct instrumentation. If the object is poorly visualized, spherical, or unsuccessfully removed by direct instrumentation, balloon-catheter removal is a preferred method.

Slide 16: 

Hemostats alligator forceps, bayonet forceps hooked probes Direct instrumentation

Direct instrumentation : 

Direct instrumentation Balloon catheters  Foley catheters (ie, 5, 6, or 8) and the Katz Extractor oto-rhino foreign body remover.  Positive pressure   Large and occlusive foreign bodies "forced exhalation," "parent's kiss"

Balloon catheters : 

Balloon catheters

Direct instrumentation : 

Direct instrumentation Suction   This technique is ideal for easily visualized smooth or spherical foreign bodies. The catheter tip is placed against the object, and suction is turned on to 100-140 mm Hg (readily supplied by standard medical suction equipment).  Irrigation

Journal review : 

Journal review Magnet  A case report demonstrated successful removal of a loose ball bearing from a nasal cavity using a household magnet

Foreign body airway obstruction : 

Foreign body airway obstruction

Site of Lodging of Foreign Body Right Main Bronchus : 

Site of Lodging of Foreign Body Right Main Bronchus The diameter of the right main bronchus is larger than the left, The angle of divergence from the tracheal axis is smaller on the right, Airflow through the right lung is greater than through the left, The carina is more likely to be located to the left of midline rather than to the right.

Foreign Body Aspiration : 

Foreign Body Aspiration Complete airway obstruction Respiratory distress Inability to speak or cough Partial airway obstruction Coughing Gagging Throat clearing Back blows/probing hypopharynx not recommended

Foreign Body Aspiration : 

Foreign Body Aspiration

Treatment : 

Treatment Goal Prompt endoscopic removal under conditions of maximal safety and minimal trauma

Management : 

Management Complete airway obstruction < one year Back blows > one year Gentle abdominal thrusts while supine Older children/adults Heimlich maneuver

Foreign Body Aspiration : 

Foreign Body Aspiration

Slide 29: 

Infants under 1 year of age: A combination of 5 back blows (with the flat of the hand) and 5 abdominal thrusts (with 2 fingers on the upper abdomen). Treatment

Slide 31: 

Finger sweep

Bronchoscopic removal : 

Bronchoscopic removal Bronchoscopy . Secretions proximal to peanut in left main stem bronchus

Complication : 

Complication respiratory distress, asphyxia, cardiac arrest, fever, laryngeal edema, pneumothorax, hemoptysis, pneumonia, bronchiectasis, and bronchial stricture surgical emphysema*

Complication : 

Complication Shift of mediastinum and flattening of the hemidiaphragm are signs secondary to air trapping. Normal

Esophageal foreign body : 

Esophageal foreign body

Foreign Bodies : 

Foreign Bodies Foreign body ingestion Foreign body aspiration Toddlers Oral exploration Lack posterior dentition Easy distractibility Cognitive development (edible?)

Foreign Body Ingestion : 

Foreign Body Ingestion Parental suspicion Symptoms Choking, coughing, dysphagia, odynophagia Physical exam Drooling, refuses p.o., fussy child Respiratory compromise

Diagnosis : 

Diagnosis Radiopaque Coins Cartilage/bones Radiolucent Hot dogs Barium swallow

Management : 

Management Removal General anesthesia Intubated Esophagoscopy Examine for ulceration/perforation Smooth-muscle relaxation agents may be used to relax the LES

Foreign Body Ingestion : 

Foreign Body Ingestion Balloon Catheter Extraction Effective in 90% Endoscopy for failures Complications Emesis Epistaxis Tracheal placement Laryngospasm Airway compromise

Complications : 

Complications Entrapment of object within a Meckel's diverticulum Perforation leading to peritonitis and advanced sepsis Metal poisoning (coins)
