Abstract Published in Canadian Journal of Surgery Reports Key Preliminary Findings of Major Prospective Study of the KCI ABThera™ Open Abdomen Negative Pressure Therapy System

Released : 17 Nisan 2012

Kinetic Concepts, Inc. announced today that an abstract referring specifically to the KCI ABThera Open Abdomen Negative Pressure Therapy System (ABThera OA NPT), states that this "prospective cohort study observed a reduction in mortality (RR 0.48, 95% CI 0.25-0.92) and an increased fascial closure rate (RR 1.5, 95% CI 1.1 – 2.0) in patients who received the ABThera versus [Barker's technique] vacuum pack."

SAN ANTONIO—April 17, 2012— Kinetic Concepts, Inc. announced today that an abstract referring specifically to the KCI ABThera Open Abdomen Negative Pressure Therapy System (ABThera OA NPT), states that this "prospective cohort study observed a reduction in mortality (RR 0.48, 95% CI 0.25-0.92) and an increased fascial closure rate (RR 1.5, 95% CI 1.1 – 2.0) in patients who received the ABThera versus [Barker's technique] vacuum pack."

This data was presented in greater detail at the 2011 World Congress of Abdominal Compartment Syndrome (WCACS). The presentation described this KCI-funded on-label study, called ABTAC, which was a prospective, observational, open-label parallel study performed to evaluate two temporary abdominal closure (TAC) techniques: ABThera OA NPT and the Barker's vacuum-packing technique. There were 280 study participants enrolled from 20 participating hospitals in the United States. Participants consisted of trauma and surgical patients who required TAC following a damage control laparotomy or treatment of either intra-abdominal hypertension or severe sepsis. A smaller subset of the study population (138 patients) received at least 48 hours of consistent TAC therapy with either ABThera OA NPT (n=94) or the Barker's vacuum-packing technique (n=44). The two groups were analyzed in terms of age, BMI, SOFA, APACHE III, and ISS scores (three well-established severity of illness grading scales) with no statistically significant differences detected across these variables.

Two important outcome measures from ABTAC were rate of primary fascial closure (primary measure) and 30-day All-Cause Mortality rate (secondary measure). Among the patients treated with at least 48 hours of consistent TAC therapy, the rate of primary fascial closure (within 30 days) was 76% for the ABThera OA NPT group and 57% for the Barker's vacuum-packing technique (p=0.03). In this same patient group, the 30-day All-Cause Mortality rate was 15% for patients treated with ABThera OA NPT and 34% for those treated with Barker's vacuum-packing technique (p=0.01).

The abstract, was also presented at the 2012 Trauma Association of Canada Annual Scientific meeting on April 13, 2012.

The ABThera Open Abdomen Negative Pressure Therapy System is indicated for temporary bridging of abdominal wall openings where primary closure is not possible and/or repeat abdominal entries are necessary. This system is intended for use in open abdominal wounds, with exposed viscera, including but not limited to abdominal compartment syndrome (ACS).
