Clinical Trial Summary
Surgical site infection (SSI) is one of main complication in surgery. It usually occurs
within 30 days post operation. The superficial SSI is an infection of skin and subcutaneous
layer, clinically presented by pus oozing. Furthermore, seroma hematoma and wound dehiscence
are also clinical signs of superficial SSI.
Nowadays, there are studies which report methods reducing SSI by placing negative pressure
drain within surgical wound. It can reduce serum in subcutaneous layer which is found in
every surgical wound, especially in clean-contaminated and contaminated wound. Many studies
show that placing negative pressure drainage within a surgical wound can reduce superficial
SSI and decrease hospital length of stay by comparing with the control group.
The objective in this study to compare the rate of SSI of clean-contaminated and contaminated
surgical wounds between the patients whose wounds are placed with negative pressure drainage
and patients who were not placed with negative pressure drainage.
Description:
This study is a randomized controlled trial, double-blinded and performs in the patient who
underwent intra-abdominal surgery. the investigators collect the data at the department of
surgery, Ramathibodi hospital. This study randomized the volunteer patient into 2 groups as
follow: the patient with placing negative pressure drainage within the surgical wound and the
patient without placing negative pressure drainage.
- Randomization To minimize the study bias, the investigators random patient into two
groups by the unassociated personnel opens an enclosed envelope after the surgical
procedure is completely performed and before the beginning of closing the skin layer.
- Blind process This study does not conceal information about surgical technique and drain
placing method. However, the investigators have controlled various surgical procedures
to reduce inequality in assessment and bias.
- Negative pressure drainage is a drainage catheter which is placed in surgical wound for
draining fluid such as hematoma, seroma, and pus. In this study the drainage the
catheter will be placed in the wound for 5 days and/or removed if fluid content is less
than 20 ml per day. Jackson-Pratt or Redivac catheter is used in this study because it
is cheap and widespread in all hospitals. The drainage catheter is placed after
completion of surgery and before skin closure.
- Surgical site infection (SSI) is infection at surgical wound which happens within 30
days post operatively and in this study will use in term of superficial SSI (pus oozing,
cellulitis and wound culture positive) If patients have SSI, the investigators remove
the drain from the patients (intervention group) and may total stitch off suture then
wet dressing combine with antibiotic.
the investigators evaluate and collect data by physical examination at post operation day 3,
day 5,day 7 and the day that patient is discharged from hospital. Then investigators follow
up the patients at 14 days and 30 days after discharged from hospital.The complication of SSI
is seroma, hematoma and wound dehiscence.
- Seroma is the retention of clear fluid in the cavity of the body such as a surgical
wound. Typical clinical presentation is fluid oozing from the wound.
- Hematoma is the retention of bloody fluid in the cavity of the body such as a surgical
wound. It can be infected which is possible to prevent by stop bleeding intraoperatively
and evaluate surgical wound every day.
- Wound dehiscence is partial or total separation of previously approximated wound edges,
due to failure of proper wound healing.
In patient case with infected wound and the investigators give antibiotics along with
dressing, but does not stitch off suture, we do not include as SSI in this study.
