A clinical outcome of using vacuum assisted dressing and conventional saline dressings in management of chronic non healing ulcer - A randomised controlled trial

After correction from the IRC&IEC, convenient sampling of patients attending op and ipd services during the study period mentioned, fulfilling the inclusion and exclusion criteria as listed will be recruited for the study, after obtaining informed written consent under the guidance of the guide and co-guide.

The nature, purpose and their roles in the study will be explained in detail, including the information that their non-participation in the study would not affect the quality of their treatment that they are to receive and that they are free to exit the study at any time. After assuring that their responses would remain confidential, an informed written consent for the same shall be obtained from all participants

Data will be collected using a pre-tested semi-structured proforma to collect sociodemographic details about the patients participating in the study.

Patients based on convenience sampling will be divided into group A& group B

Pre operatively in both the groups detailed history will be taken and routine investigations like HB, TC, DC, ESR, RBS, SEROLOGY, ECG, LFT, RFT, PUS C/S will be done.

Wound preparation will be done by removing the dressing from the wound and discarded. Aculture swab for microbiology culture will be taken before the wound irrigation with normal saline.

Surgical debridement will be done and adequate haemostas is will be achieved.

Sterile, open-cell foam dressing will be gently placed into the wound cavity. the site will be then sealed with an adhesive drape ensuring that the drapes covered the foam and the fenestrated tube inside. Drapes should be placed till three to five centimeters of surrounding healthy tissue.

Controlled pressure will be uniformly applied to all tissues on the inner surface of the wound using centralized vacuum pump. The pressure could be delivered either continuous or intermittent type, ranging from 50 to 125 mm hg. The foam dressing will get compressed in response to the negative pressure. The pressure will be applied continuously for the first 48 hours and then changed to continuos or intermittent therapy

Saline dressing daily will be done in control group

After 5 days the vac will be removed and the wound healing rate will be assesed; culture swab for microbiology will be taken

Data will be tabulated, analyased based on statistical tests

Results obtained and conclusions will be drawn
