Objectives/Interrogation: Many wounds of extremity were intractable despite of adequate debridement and wound closure which it formed dead space or infectious focus. We tried to treat these intractable wound effectively with strong negative pressure suction using 50cc disposable syringe. We report the method and result of this treatment.

Methods: From Sep 2007 to Aug 2015, 150 wounds of 121 patients were treated with NPST. Average age was 49 years with 87 men. Location of wounds were 98 cases of hand, 27 forearm and arm, 11 foot, 10 thigh and leg and 4 trunk. After through debridement of dead or infected tissue, suction tube using connecting tube for IV fluid or butterfly needle was insertion into the wound with multiple hole. Wound was closed with airtight and 50cc disposable syringe was connected to the tube. Negative pressure suction was applied with drawback of piston of syringe to 50mm marking line. Negative pressure was adequately controlled remaining 0~5cc air into the syringe. Syringe was emptied out more than 10 cc of drainage and maintained from 3 to 14 days.

Results and Conclusions: 134 of 150 wounds were treated with this method despite of infectious or dirty wound. 110 of 121 patients were treated by 1st try of NPST, 7 patients were 2nd try, 3 patients were 3rd try, and one patient was 4th try of NPST.

NPST with 50cc disposable syringe was useful method for the treatment of intractable wound due to through removal of hematoma and infection exudate, obliteration of dead space, and tight contact of separated wound with strong negative pressure into the wound. NPST had the great advantage than can be easy done without any special equipment.
