Canine GDV Bloat Emergency Treatment

Cole here. Classic presentation. This is a surgical emergency, and time is tissue. Our job is to get this dog to the OR alive in the next 60-90 minutes. Don't delay surgery for perfect numbers.

Here’s the stabilization plan:

IV Access & Resuscitation: Place two large-bore (16-18g) intravenous catheters in the cephalic or saphenous veins. Avoid the jugular if you can, as it may be compromised by abdominal pressure. Start aggressive fluid resuscitation with an isotonic crystalloid like Plasmalyte or LRS. Begin with a 10-20 mL/kg bolus over 15 minutes and reassess perfusion parameters (HR, pulse quality, BP, mentation). Repeat boluses as needed. A concurrent hypertonic saline bolus (7.5% NaCl at 4 mL/kg over 10 min) can rapidly expand intravascular volume while you get crystalloids on board.

Decompression: While fluids are running, decompress the stomach immediately. If the patient is too unstable or you can't pass an orogastric tube quickly, perform percutaneous gastrocentesis (trocarization). Use a 14-16g catheter over the most tympanic area on the right paracostal flank. This buys you time and improves venous return.

Diagnostics & Monitoring: Get a baseline lactate, PCV/TS, BUN, and electrolytes. A right lateral abdominal radiograph is all you need for confirmation (pylorus dorsal to the fundus, "double bubble"). Place an ECG immediately and monitor continuously. Ventricular arrhythmias are common pre- and post-op due to myocardial ischemia.

Medications: Start analgesia now with a pure mu-agonist like methadone (0.2 mg/kg IV) or a fentanyl CRI. Pain management is critical for stability. Administer a broad-spectrum antibiotic like ampicillin/sulbactam (30 mg/kg IV). If you see significant ventricular ectopy (>10-15 VPCs/min, R-on-T, or runs of V-tach) causing hypotension, treat with a lidocaine bolus (2 mg/kg IV) followed by a CRI.

James, my goal is to correct the hypovolemic shock and mitigate the obstructive shock before he gets to you. I'll be managing the perfusion and arrhythmias. Over to you for your preferred anesthetic protocol considerations and the surgical plan for derotation and gastropexy. Let me know what parameters you want to see before you induce.

This is a classic presentation, and time is critical. Dr. Cole will cover the initial stabilization; my focus is on getting this dog to the OR and performing a successful derotation and gastropexy.

Once ECC has initiated fluid resuscitation and attempted decompression, I'm ready to proceed to surgery. I don't need a perfectly stable patient—I need one that can survive induction. The definitive treatment for GDV is surgical.

My surgical approach is a standard ventral midline celiotomy. First, I de-rotate the stomach, which is typically rotated clockwise when viewed from my position at the patient's side. The key is to grab the pylorus with my right hand and the fundus with my left, then push the pylorus ventrally and to the right while pulling the fundus dorsally and to the left.

Once de-rotated, I assess viability. I'm looking at the color of the gastric wall, assessing for peristalsis, and checking for bleeding after a serosal incision. If there are any non-viable, gray-green or black sections, a partial gastrectomy is required. Similarly, I'll evaluate the spleen. If it's torsed, thrombosed, or has avulsed vessels, a splenectomy is necessary. These findings significantly alter the prognosis, and it's a conversation I have with owners pre-operatively.

The final and most crucial step is the gastropexy to prevent recurrence. My preferred technique is an incisional gastropexy. I create a seromuscular incision in the antrum of the stomach, parallel to the long axis, and a second incision through the transversus abdominis muscle on the right body wall, just caudal to the last rib. I then suture the edges of the gastric incision to the edges of the body wall incision in a simple continuous pattern with a long-lasting absorbable suture like 2-0 PDS. This creates a permanent adhesion.

Post-operatively, the ECC team will manage the arrhythmias, but from a surgical standpoint, we monitor for signs of peritonitis from gastric necrosis or dehiscence. We'll start with water 12-24 hours post-op, followed by small, frequent meals of a bland diet.
