Background and Aims:There is controversy regarding the ability of preoperative pulmonary functiontesting to predict postoperative pulmonary complications after elective abdominal surgery. This study wasundertaken to determine whether preoperative pulmonary function tests are helpful in stratifying the riskof developing postoperative pulmonary complications in patients undergoing elective laparotomy.Materials and Methods:We conducted a retrospective case-control study, and identified 19 patientswith postoperative pulmonary complications and compared these patients with 64 control patients matchedfor type of operation, age, and gender to compare pre- and intraoperative variables.Results:Conditional logistic regression analyses showed that none of the results from spirometry testingwere significantly associated with the development of postoperative pulmonary complications. Serum albuminlevel(<3.9g/dl)was the only variable independently associated with the development of postoperativepulmonary complications among all of pre- and intraoperative variables investigated.Conclusions:Preoperative pulmonary function testing did not predict the risk of developing postoperativepulmonary complications in patients undergoing elective abdominal surgery. Based on the results ofthis study, the routine use of preoperative spirometry should be reconsidered.
