OPTICC: A multicentre trial of Occult Pneumothoraces subjected to mechanical ventilation: The final report - 20/05/21
Abstract |
Introduction |
Patients with occult pneumothorax (OPTX) requiring positive-pressure ventilation (PPV) face uncertain risks of tension pneumothorax or chest drainage complications.
Methods |
Adults with traumatic OPTXs requiring PPV were randomized to drainage/observation, with the primary outcome of composite “respiratory distress” (RD)).
Results |
Seventy-five (75) patients were randomized to observation, 67 to drainage. RD occurred in 38% observed and 25% drained (p = 0.14; Power = 0.38), with no mortality differences. One-quarter of observed patients failed, reaching 40% when ventilated >5 days. Twenty-three percent randomized to drainage had complications or ineffectual drains.
Conclusion |
RD was not significantly different with observation. Thus, OPTXs may be cautiously observed in stable patients undergoing short-term PPV when prompt “rescue drainage” is immediately available. As 40% of patients undergoing prolonged (≥5 days) ventilation (PPPV) require drainage, we suggest consideration of chest drainage performed with expert guidance to reduce risk of chest tube complications.
Level of evidence |
Therapeutic study, level II.
