Development of New Predictive Model to Reduce Postoperative Respiratory Complication
(June 22, 2011)
A new study in the July issue of Anesthesiology
helped developed a model that could determine which patients are at high risk of developing acute lung injury (ALI). Postoperative ALI is a life-threatening respiratory complication, with an estimated mortality exceeding 45 percent in certain surgical populations. Since ALI has limited treatment options, prevention may be more effective than treating the syndrome.
Researchers from Mayo Clinic in Rochester, MN, performed a secondary analysis of a prospective database and compared patients who developed ALI versus those who did not. From the analysis, preoperative risk factors for postoperative ALI were identified and evaluated for inclusion in the surgical lung injury prediction (SLIP) model.
“The SLIP model will help physicians study targeted prevention strategies in patients who are at moderate or high risk of ALI, while avoiding potential harm in patient’s who are at low risk,” said lead study author Daryl J. Kor, M.D.
Findings revealed that out of 4,366 patients, 2.6 percent developed early postoperative ALI. Patients who developed ALI were older and more likely to undergo high-risk cardiac, vascular, and thoracic surgery. Patients with diabetes mellitus, chronic obstructive pulmonary disease, gastroesophageal reflux disease, and alcohol abuse also were discovered to be at risk for ALI.
The model categorized all SLIP scores into three groups of patients: low risk (SLIP score ≤9), moderate risk (SLIP score 10 to 26), and high risk (SLIP score ≥27). “Future research will go one step further and test strategies to prevent postoperative ALI in patients who are determined to be at high risk using the SLIP score,” continued Dr. Kor.

THE AMERICAN SOCIETY OF ANESTHESIOLOGISTS
Founded in 1905, the American Society of Anesthesiologists (ASA) is an educational, research and scientific society with more than 52,000 members organized to raise and maintain the standards of the medical practice of anesthesiology. ASA is committed to ensuring physician anesthesiologists evaluate and supervise the medical care of patients before, during and after surgery to provide the highest quality and safest care every patient deserves.
