What are the indications of under water seal drainage?


  • Pneumothorax (spontaneous, tension, iatrogenic, traumatic)
  • Pleural collection – Pus ( empyema), blood ( hemothorax), chyle ( chylothorax)
  • Malignant effusions (pleurodesis)
  • Postoperative.
  • Thoracotomy.
  • Video-assisted thoracoscopic surgery (VATS)

What is a water seal drainage?

Chest drains also known as under water sealed drains (UWSD) are inserted to allow draining of the pleural spaces of air, blood or fluid, allowing expansion of the lungs and restoration of negative pressure in the thoracic cavity. The underwater seal also prevents backflow of air or fluid into the pleural cavity.

What are the indication for a patient to need a chest or Intrapleural drain?

Chest drains are inserted as an invasive procedure to; Remove fluid/air from the pleural space/mediastinum, and/or Re-expand the lungs and restore negative intrapleural pressure and respiratory function. Conditions that require a chest drain include; Pneumothorax – “Air in the pleural cavity”.

What are the types of underwater seal drainage?

Three types of underwater seal drainage systems are available: the 1-bottle, the 2-bottle, and the 3-bottle system. o In the 1-bottle system the chest drain is connected by collecting tubing to a tube approximately 3 cm under water (the seal) in the underwater-seal bottle while another vent tube is open to atmosphere.

What are the complications of water seal drainage?

Pleural drain complications

  • Tension pneumonthorax.
  • Trauma to intrathoracic structures, intra-abdominal structures and intercostal muscles.
  • Re-expansion pulmonary oedema.
  • Haemorrhage.
  • Incorrect tube position.
  • Blocked tube.
  • Pleural drain falls out.
  • Subcutaneous emphysema.

What are the complications of underwater seal drainage?

Why is a water seal so important in drainage systems?

The middle chamber of a traditional chest drainage system is the water seal. The main purpose of the water seal is to allow air to exit from the pleural space on exhalation and prevent air from entering the pleural cavity or mediastinum on inhalation.

Is water Seal suction?

The water chamber holds a column of water, which prevents air from being sucked into the pleural space with inhalation. The suction chamber can be attached to continuous wall suction to remove air or fluid, or it can be placed on “water seal” with no active suction mechanism.

What is the difference between wet and dry suction?

Wet suction control systems regulate suction pressure by the height of the column of water in the suction control chamber. Dry suction control systems regulate suction pressure mechanically rather than with a column of water.

What is the definition of a water seal drainage system?

Water seal drainage. 3. Definition Water seal drainage system is a closed chest drainage system used to allow air and fluid to escape from the plural space with each exhalation and to prevent their return flow with each inhalation watersealdrainage.

What does water seal mean for chest drainage?

Water seal chest drainage means that a column of water in a bottle seals off the atmospheric air preventing from entering the chest drainage tube and thereby in the pleural sac

What does watersealdrainage stand for in chest tube?

How is fluid collected in an underwater seal drain?

Placed in series between first chamber and ICC Collects fluid from pleural cavity Level of fluid in chamber limits the amount of suction applied from external suction Excess suction draws air into chaber through vent rod which is then suctioned out
