The purpose of this study is to investigate whether if KatGuide (a new developed medical device) improves the placing of a large bore chest tube in the pleural cavity compared to the conventional method.

Device: KatGuide versus conventional method (forceps)
Procedure: Chest tube insertion
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Chest tube placement [ Time Frame: 3 hours ]
    X-ray examination of the chest is performed within 3 hours after the chest tube insertion, to evaluate if the placement of the chest tube is acceptable.

Secondary Outcome Measures:
  • Length of hospital stay [ Time Frame: 5 days ]
    The hospital stay depends on how long time it takes to solve the chest tube related problem. In a few patients it takes only one day, but in severe cases it may take weeks before the patient can be discharged. We predict, that the patient will be in hospital for a mean time of 5 days.

  • Time with chest tube [ Time Frame: 3 days (mean time) ]
    A few patients can have the chest tube removed in only one day, but some patients must have a chest tube for weeks. We predict that the patients will have a chest tube in a mean time of 3 days.

  • Infection in wound [ Time Frame: 4 weeks ]
    4 weeks after the chest tube insertion, the patient is contacted and the patient is asked whether there are problems with infection of the wound.

  • Number of chest tubes [ Time Frame: 7 days (mean time) ]
    It is observed whether the patient has multiple chest tubes inserted in the pleural cavity at the same side. It is predicted, that these patients are hospitalized longer than patients with only one chest tube. We predict, that these patients are hospitalized for a mean time of 7 days.

Arms Assigned Interventions
Active Comparator: KatGuide
Chest tube insertion is performed by using the KatGuide
Device: KatGuide versus conventional method (forceps)
According to randomization Chest tubes are placed in the pleural cavity by using the KatGuide device.
Active Comparator: Conventional group
Chest tubes are inserted by using conventional method (forceps) for large bore chest tube insertion.
Procedure: Chest tube insertion
The chest tube is placed in the pleural cavity by using a forceps (conventional method) or KatGuide
