Drainage volume of thoracic or nasogastric tube before and post E-TNPD. (A) Before the E-TNPD therapy intervention, the median thoracic drainage volume was 252 ml (range: 201 to 283 ml) with purulent effusion. After institution of the E-TNPD therapy, the median thoracic drainage volume markedly decreased to 94 ml per day (range: 9 to 163 ml). (B) E-TNPD promoted resolution of nasogastric tube drainage. Nasogastric tube mean drainage decreased from 202 ml per day (range: 124 to 311 ml) to 115 ml per day (range: 63 to 176 ml) for Cases 1 to 4. For Case 5, the mean nasogastric tube drainage increased from 168 ml to 252 ml, but the mean thoracic drainage decreased from 283 ml to 163 ml. Vol, volume.
