Abstract:
Objective To observe the value of immediate CT-guided small negative pressure thoracic drainage for pneumothorax after percutaneous lung biopsy(PTLB).Methods Totally 172 patients of unilateral pneumothorax after PTLB were retrospectively enrolled,including 83 patients underwent immediate CT-guided small negative pressure(about 30 mmHg)thoracic drainage after PTLB(group A)and 89 patients underwent bedside closed thoracic drainage after PTLB(group B).Clinical data before treamtent,degree of pneumothorax,the duration of catheterization,pain degree during catheterization(visual analogue scale[VAS]),blood oxygen saturation after treatment,the ratio of immediate relief of clinical symptoms,duration of drainage retention,duration of hospitalization after treatment and the occurrence of pleural reaction were compared between groups.Results Drainage went smoothly in both groups.No significant difference of clinical data before treatment nor pneumothorax degree was found between groups(all P＞0.05).Compared with those in group B,the duration of catheterization was shorter,and pain degree was lower during drainage in group A(both P＜0.001).After drainage,blood oxygen saturation and the proportion of immediate relief of clinical symptoms in group A were both higher than those in group B,while the duration of drainage retention and hospitalization were both shorter in group A than those in group B(all P＜0.001).Pleural reaction occurred in 2 patients in group A and 1 patient in group B,and no significant difference of pleural reaction was detected between groups(P=0.520).Conclusion Immediate CT-guided small negative pressure thoracic drainage was effective and safe for pneumothorax after PTLB.
