Abstract

Postoperative pulmonary complications (PPCs) are a heterogeneous group of respiratory complications that significantly alter the postsurgical outcome of patients. Numerous studies have been conducted to investigate the prevalence, clinicopathologic and radiographic presentation of PPCs, and especially the risk factors for their development in humans. Risk prediction models have reduced PPC-associated postoperative patient morbidity and mortality in humans. However, a knowledge gap exists in understanding the risk factors for PPCs in veterinary small animal surgical patients. This study aims to determine the frequency, nature of PPCs and investigate the perianesthetic risk factors of PPCs among cats and dogs that underwent laparotomy in UVH from 2019 to 2021. A total of 117 animals without preoperative pulmonary pathology were analyzed for factors of patient signalment, American Society of Anesthesiologists (ASA) physical status (PS), fasting duration, perioperative vomiting, preoperative hypoalbuminemia, anesthetic and analgesic protocol, anesthesia duration, intraoperative fluids total volume, correction of intraoperative hypotension with fluids, body positioning and surgical site using Chi-square test. Correction of hypotension with fluids was statistically higher in animals that developed PPCs than those that did not (nPPC). Animals with a body condition score (BCS) of 3 or below, and those with lower abdominal surgery, were more likely to acquire PPCs from this study. Routine ovariohysterectomy cases recorded the highest PPC count (n=6), followed by pyometra (n=2) and hepatobiliary surgeries (n=2). PPCs included suspected atelectasis, pulmonary edema, ventilator-associated or aspiration pneumonia, chemical pneumonitis, bronchitis, tracheitis, bronchospasms, pneumothorax and short-term postoperative hypoxemia. Animals presented with risk factors should be closely monitored in their postoperative stage to prevent the development of PPCs.
