Common Postoperative Complications-Slides

Pdf Summary

This presentation by Dennis Chang, MD, and Kurt Pfeifer, MD, addresses common postoperative complications through a detailed case study of a 60-year-old man undergoing partial colectomy for stage 1 colorectal cancer. The case highlights key postoperative issues: urinary retention, fever, ileus, and atrial fibrillation.<br /><br />Postoperative urinary retention (POUR) affects 4-13% of surgical patients, with risk factors including male gender, age, BPH, and certain medications. Management involves bladder scanning, catheterization if needed, spontaneous voiding trials, and prevention strategies such as voiding before anesthesia and withholding anticholinergic meds. Alpha-1 antagonists may reduce POUR incidence specifically in anorectal and pelvic surgeries.<br /><br />Postoperative fever is common (10-40%) and often noninfectious within the first 72 hours (inflammation). Afterward, infections following the "Rule of Ws" (Wind - pneumonia; Water - UTI; Wound - SSI; Walking - VTE; and others) are considered. Early fever evaluation relies on history and physical exam to guide diagnostics, with routine testing showing low yield unless clinically indicated.<br /><br />Postoperative ileus, defined as persistent GI dysfunction after 4 postoperative days, occurs in 12-17% of colectomy patients and is associated with surgical/medical factors like open surgery, electrolyte imbalances, and opioid use. Diagnosis is clinical with radiological confirmation. Treatment involves correcting underlying causes, minimizing opioids, encouraging early ambulation, and nutritional support. Evidence for interventions like gum chewing or coffee is limited or mixed.<br /><br />Postoperative atrial fibrillation (POAF) occurs in 2.5–4.4% of noncardiac surgeries, typically around day 3. Risk factors include age, cardiac disease, and surgery type. Management emphasizes rate/rhythm control, evaluation of triggers, and shared anticoagulation decisions based on stroke risk. Recurrence is common, warranting close follow-up.<br /><br />Overall, the presentation stresses the importance of thorough clinical assessment, timely intervention, tailored prevention, and careful patient and surgeon education to optimize postoperative outcomes.
