The causes of postoperative respiratory complications remain unknown. Therefore, we evaluated postoperative factors associated with respiratory complications in nontrauma patients who had undergone OA management using propensity score matching, with a focus on OA-related risk factors.METHODS: This retrospective analysis included subjects who underwent OA management during a 4-y study period. Age, body mass index, and smoking history were selected as covariates. After propensity score matching, we compared postoperative factors (ie, first operative time, duration of OA, initial 3-d fluid balance, length of ICU stay, and in-hospital mortality) in 2 groups of subjects: those who had post-OA respiratory complications (PORCs) and those who did not.RESULTS: 60 subjects (33 men and 27 women) were identified; 38.3% of these subjects had PORCs. After propensity score matching, 18 subjects were matched. The 3-d fluid balance was significantly higher in subjects with PORCs than in those without PORCs (3,513 mL vs 1,087 mL; P = .03).CONCLUSIONS: To our knowledge, this is the first study to examine factors associated with respiratory complications following OA in nontrauma subjects. After adjusting for known co-factors associated with postoperative respiratory complications, the 3-d fluid balance was identified as a significant risk factor for PORCs in subjects who had undergone OA. Clinicians should pay attention to the incidence of PORCs in OA subjects with a positive fluid balance after emergency abdominal surgery. ER -
