The influence of chest tube size and position in primary spontaneous pneumothorax
2017
Background: Optimal
chest tubeposition in the
pleural cavityis largely unexplored for the treatment of primary spontaneous
pneumothorax(PSP). We investigated whether type, size and position of
chest tubesinfluenced duration of treatment for PSP. Methods: A retrospective follow-up study of all patients admitted with PSP over a 5-year period. Traumatic, iatrogenic and secondary
pneumothoraxeswere excluded. Gender, age, smoking habits, type and size of
chest tubeused (
pigtailcatheter or surgical
chest tube) were recorded from the patients’ charts. All chest X-rays upon admittance and immediately following
chest tubeplacement were retrieved and re-evaluated for size of
pneumothorax(categorized into five groups) and location of the
chest tubetip (categorized as upper, middle or lower third of the
pleural cavity). All data were analysed in a Cox proportional hazards regression model. Results: We identified 134 patients with PSP. Baseline characteristics were similar for patients treated with surgical
chest tubesand
pigtailcatheters.
Chest tubeduration was not significantly influenced by position of the
chest tubetip, but was significantly longer in females (P Conclusions: Contrary to common belief and guidelines recommendation the position of a
chest tubein the
pleural cavitydid not significantly influence
chest tubeduration, but it was significantly longer in patients who were treated with a surgical
chest tube.
