Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

968
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.

Suctioning the Oropharyngeal Airway

384
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...

Tracheostomy Suctioning I: Pre-Procedural Steps

1.1K
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

515
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Cardiopulmonary Resuscitation II: ACLS Airway Management01:22

Cardiopulmonary Resuscitation II: ACLS Airway Management

97
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Summary
This summary is machine-generated.

Low suction (LS) did not shorten air leak duration after lung resection compared to standard suction (SS). Standard suction may be preferred when air leaks are present, despite similar chest tube duration and hospital stay.

Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Critical Care Medicine

Background:

  • Chest tube management post-pulmonary resection lacks standardization.
  • Practices vary in suction levels, drain type, and removal criteria.

Purpose of the Study:

  • To compare standard suction (SS) with low suction (LS) for chest tube management after minimally invasive lung resection.
  • To evaluate the primary outcome of air leak duration and secondary outcomes including chest tube duration and length of stay.

Main Methods:

  • A randomized study compared SS (-20 cmH2O) to LS (-8 cmH2O) in patients undergoing minimally invasive lung resection.
  • Chest tubes were removed based on drainage volume (≤450 mL/24 h) and air leak (≤20 mL/min over 6 h).

Main Results:

  • No significant differences were observed in air leak duration, chest tube duration, or hospital stay between SS and LS groups.
  • The incidence of prolonged air leak was similar (8% SS vs. 11% LS).
  • Low suction was associated with more pleural interventions (11% vs. 3%) and a trend towards increased subcutaneous emphysema.

Conclusions:

  • A single 24 Fr Blake drain and a 450 cc/24 h drainage threshold are safe and effective for chest tube removal.
  • Low suction offers no advantage over standard suction for air leak duration.
  • Standard suction may be preferable due to a higher requirement for pleural interventions and a trend for increased subcutaneous emphysema with low suction.
