Study Notes
Intravenous Access and Fluid Resuscitation
- Large-bore needles are preferred for rapid fluid resuscitation in patients with significant volume loss.
- Tachycardia is often the first clinical sign indicating acute blood loss.
- Orthostatic hypotension may appear early and can suggest substantial blood loss.
- Symptoms may include dry mucous membranes and mucosal pallor.
Diagnostic Measures
- Complete blood count (CBC) should assess hemoglobin/hematocrit levels.
- Blood typing is essential for transfusion preparation.
- Transfusion is considered when hemoglobin levels drop below 7 g/dL, particularly with ongoing blood loss.
Examination and Source Identification
- An otolaryngologist should utilize proper protective equipment, including eye protection.
- Necessary tools include towels, basins, light sources, suction devices, and varying calibers of suction tips.
Preventive Measures for Bleeding
- Topical moisturization and nasal humidification can help prevent nasal trauma.
- Patients should be cautioned against direct trauma to the nasal area, which could worsen bleeding.
Conservative Management of Epistaxis
- Firm pressure should be applied to the soft tissue portion of the anterior nose for 15 to 20 minutes while the patient leans forward.
- "No peeking" strategy emphasizes avoiding premature pressure release to check for cessation of bleeding.
- Ice packs can be applied over the forehead/face to aid in bleeding control.
Topical Treatments
- Topical vasoconstrictors like oxymetazoline should not be used for more than three days to avoid rhinitis medicamentosa.
Greater Palatine Canal Injection
- Use a long 25-gauge syringe needle, bent 1.5 cm, aimed at the greater palatine canal, administered with 1 mL diluted epinephrine.
Directed Treatment and Hemostatic Agents
- Cautery options include chemical (e.g., silver nitrate) or electrical (bipolar or monopolar) methods.
- Absorbable topical hemostatic materials promote coagulation, examples include oxidized regenerated cellulose (Surgicel) and gelatin sponge (Gelfoam).
Nasal Packing
- Anterior nasal packs are the first-line treatment; posterior nasal packing is used for severe or refractory cases.
- Posterior packing can be achieved with devices like a Foley catheter and tonsil sponges.
Advanced Interventions
- Endoscopic procedures include sphenopalatine and maxillary artery ligation.
- External carotid artery ligation is a last-resort option for severe epistaxis.
- Embolization is also considered for refractory bleeding.
Pediatric Considerations for Foreign Bodies
- Most foreign body incidents involve boys under three years old, commonly choking on peanuts or vegetable matter.
- Coins and pins are frequent esophageal foreign bodies.
- Radiographs are useful in identifying tracheal versus esophageal foreign bodies, with coins showing a single rim and button batteries exhibiting a halo appearance.
- Urgent bronchoscopy is mandated when there is suspicion of airway obstruction.
Esophageal Foreign Body Management
- Decision to remove depends on the object type, location, patient age, and time since ingestion.
- Symptomatic patients or aged children with retained sharp or caustic objects require immediate intervention.
- Major complications may arise from delays in treatment.
Recurrent Respiratory Papillomatosis
- Rare condition caused by HPV types 6 and 11; leads to hoarseness and airway obstruction.
- Surgical removal can be performed using a variety of techniques including lasers and microlaryngoscopy.
Congenital and Acquired Subglottic Stenosis
- Subglottic lumen diameter is normally 4.5-5.5 mm in full-term neonates and about 3.5 mm in preterm infants.
- Severe respiratory distress and stridor can be immediate symptoms of congenital stenosis.
- Acquired stenosis typically arises from trauma, particularly from blunt neck injuries.
- Symptoms may become pronounced following upper respiratory infections, necessitating close monitoring and evaluation.
