Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
Equipment Required

Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Endotracheal Tube Extubation

Endotracheal Tube Extubation

Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.

Tracheostomy Decannulation

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Endotracheal Intubation II: Nursing Management

Endotracheal Intubation II: Nursing Management

Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Suctioning the Oropharyngeal Airway

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Summary

Air reflux is common after external dacryocystorhinostomy (DCR) surgery, persisting in most cases but rarely causing issues. This reflux is linked to successful symptom relief, not surgical failure.

Area of Science:

Ophthalmology
Oculoplastics
Surgical Outcomes

Background:

External dacryocystorhinostomy (DCR) is a common surgical procedure for nasolacrimal duct obstruction.
The occurrence and significance of postoperative air reflux following DCR are not well-established.

Purpose of the Study:

To determine the prevalence and natural history of air reflux after external DCR.
To investigate the relationship between air reflux and successful symptomatic outcomes.

Main Methods:

A structured telephone interview was conducted with patients over one year post-lacrimal surgery.
Patients were questioned about the presence of air reflux and experienced lacrimal symptoms.

Main Results:

Air reflux was observed in 47% of 98 external DCR operations and persisted in 78% of affected eyes at a mean follow-up of 58 months.

Membranectomy did not significantly alter the incidence of air reflux compared to procedures without membranectomy.

Air reflux was associated with a higher success rate (RR 1.22, P=.02) and was less likely to be associated with unchanged or worse symptoms (RR 0.28, P=.03).

Conclusions:

Air reflux is a frequent finding after external DCR, typically persisting but rarely problematic.
The presence of air reflux correlates with successful symptomatic improvement following DCR.
The findings suggest the valve of Rosenmüller may not function as a strict one-way valve for air.
