Postoperative management of the large colon volvulus patient.
Horses with large colon volvulus (LCV) often require intensive postoperative medical management. Although early referral and surgical intervention are critical for minimal postoperative complications and a successful outcome, this is often not possible for many reasons. Endotoxemia, extensive mucosal damage with subsequent severe hypoproteinemia, and focal ischemic necrosis are the major causes of postoperative morbidity and mortality. Although fluid therapy, flunixin meglumine, and antimicrobials are still the mainstay of perioperative management, synthetic colloids are being used to maintain plasma oncotic pressure, hyperimmune antiendotoxic plasma and polymixin B are being used for management of endotoxemia, and lidocaine and constant rate infusion of butorphanol can be used for postoperative analgesia. The use of heparin, dimethyl sulfoxide, and corticosteroids for management of LCV are still controversial. Future studies are required to investigate nutritional improvement and methods to manage cases after surgery to prevent recurrence.
