Because the provided reference material is extremely limited, a comprehensive guide to posterior nasal packing is assembled from general medical knowledge. Posterior nasal packing aims to control bleeding originating from the back of the nasal cavity. It's crucial to note that posterior nasal packing should be performed by trained medical professionals, such as ENTs (Ear, Nose, and Throat specialists) or emergency medicine physicians, and requires appropriate analgesia and monitoring.
Here's a breakdown of how posterior nasal packing is typically performed:
Steps for Placing Posterior Nasal Packing
-
Preparation:
- Explain the procedure to the patient and obtain informed consent.
- Ensure adequate analgesia is provided. This might involve topical anesthetics, intravenous analgesics, or conscious sedation depending on the patient's condition and institutional protocols.
- Gather necessary equipment:
- Posterior nasal pack (e.g., Foley catheter, pre-made posterior pack, or rolled gauze)
- Tape or umbilical clamp
- Scissors
- Lubricant (e.g., K-Y jelly)
- Nasal speculum
- Bayonet forceps
- Anterior nasal packing material (e.g., nasal tampons, Merocel sponges)
- Suction and appropriate suction catheters
- Local anesthetic with vasoconstrictor (e.g., lidocaine with epinephrine)
- Gloves, mask, and eye protection
-
Anterior Nasal Examination:
- Use a nasal speculum and light source to visualize the nasal cavity and identify any potential anterior bleeding sites.
- Control anterior bleeding with direct pressure, topical vasoconstrictors (e.g., oxymetazoline), or anterior nasal packing, if present.
-
Posterior Nasal Pack Placement (Foley Catheter Method):
- Lubricate the tip of a Foley catheter (typically 10-14 French).
- Gently insert the catheter through the bleeding nostril until the tip is seen in the oropharynx (back of the throat).
- Inflate the balloon with saline (typically 5-10 mL, but follow the manufacturer's recommendations). Do not overinflate.
- Gently pull the catheter anteriorly until the balloon is seated snugly in the posterior nasal choana (the opening between the nasal cavity and the nasopharynx). This tamponades the posterior nasal bleeding.
- Secure the catheter at the nostril with tape or an umbilical clamp to maintain tension. A small piece of gauze or padding between the clamp/tape and the nostril skin can prevent pressure sores.
- Alternatively, a commercially available pre-formed posterior nasal pack may be used and placed according to manufacturer's instructions.
-
Anterior Nasal Packing (if needed):
- Following posterior pack placement, anterior nasal packing is usually placed to provide further compression and support.
- Insert appropriate anterior nasal packing materials (e.g., nasal tampons or Merocel sponges) into the affected nostril to fill the nasal cavity.
-
Bilateral Packing Considerations:
- If bleeding continues despite unilateral posterior packing, bilateral posterior packing may be necessary.
- Important: Bilateral posterior packing increases the risk of complications such as hypoxia, bradycardia, and increased blood pressure. Continuous cardiac monitoring and pulse oximetry are essential.
-
Post-Procedure Care and Monitoring:
- Monitor the patient's vital signs, including heart rate, blood pressure, and oxygen saturation.
- Provide supplemental oxygen if needed to maintain adequate oxygen saturation.
- Administer analgesics as needed for pain control.
- Consider antibiotics to prevent sinusitis or toxic shock syndrome.
- Consult an ENT specialist for further evaluation and management.
-
Pack Removal:
- Posterior nasal packs are typically left in place for 48-72 hours.
- The balloon of the Foley catheter is deflated and the catheter is gently removed by a trained medical professional.
- Anterior nasal packing is also removed at this time.
- The patient should be monitored for re-bleeding after pack removal.
Potential Complications:
- Pain and discomfort
- Nasal necrosis (tissue death)
- Sinusitis
- Septal perforation
- Hypoxia and bradycardia (especially with bilateral packing)
- Toxic shock syndrome
