Kneel for a solution! My family Zhuizhu (1 year-old, female cat, 5.5kg) went to change the dressing for the second time on the fifth day after sterilization, and found that the wound did not heal, not only oozing blood, but also the place where the needle was stitched was cracked.

The chase is usually super good. Friends around her often regard her as a fat cat model. I wonder why she didn't survive sterilization because she is so tall and strong. With so many cats sterilized, I haven't heard of anyone whose cat can't recover after sterilization.

It's lying down now, with no strength at all, which worries me! What should I do? !

Understand your anxiety. If it's a regular hospital and experienced doctors chase after sterilization, will the problem lie in chasing a fat cat? Because, in one case, fat is liquefied after surgery.

What is cat fat liquefaction?

Cat fat liquefaction usually occurs 5 ~ 7 days after abdominal surgery. The subcutaneous tissue of the cat surgical incision is free, and yellow liquid can ooze from the eye of the needle or incision after extrusion. In severe cases, you can see all the skin cracking from the eye of the needle.

Although there is fluid exudation, the muscle tissue heals well, the incision has no inflammatory manifestations such as redness, swelling and heat pain, and the subcutaneous tissue has no necrosis. At the same time, there was no obvious abnormality in routine white blood cells, and no bacteria were found in exudate puncture microscopy.

Why is there fat liquefaction after operation?

1. Obesity factors

Obesity is the main cause of fat liquefaction in cat incision. Fat cats have thick subcutaneous fat, which is easy to cause adipose tissue ischemia during operation, leading to aseptic necrosis and exudation.

2. Surgical factors

Possibility 1: During the operation, alcohol enters the incision and dissolves the fat, resulting in fat liquefaction.

Possibility 2: Rough operation, squeezing and clamping to destroy adipose tissue.

Possibility 3: The suture is too tight and too dense, and tissue ischemia leads to fat liquefaction.

Possibility 4: Incomplete hemostasis during operation may lead to hematoma or fat liquefaction.

Possibility 5: The use of high-frequency electrotome leads to necrosis of adipose tissue after combustion, leading to fat liquefaction.

Possibility 6: the operation time is too long, the probability of incision infection increases, and the adipose tissue is exposed to the air for a long time, which leads to dry injury and poor blood supply, which may lead to fat liquefaction.

3. Nutritional factors

Diabetes, anemia and low protein will all affect wound healing. Even for sterilized cats, preoperative blood routine and biochemical examination are helpful to screen potential risks, thus reducing the occurrence of postoperative fat liquefaction.

How to prevent postoperative fat liquefaction?

1. Parents should communicate with doctors before operation and know the operation process clearly in the hospital. Routine blood tests and biochemical tests are needed before operation. Animals with anemia, low albumin and diabetes should be corrected before operation, or the operation should be postponed according to the situation.

2. For obese cats, infrared irradiation can be carried out on the second day after operation for half an hour every day for three consecutive days, which is helpful to prevent fat liquefaction.

The following are the requirements for doctors, which parents can understand. During the operation, doctors should strictly carry out aseptic operation; Move gently, stop bleeding carefully, protect the incision and reduce the exposure time of the incision; Before suturing subcutaneous tissue, rinse with normal saline to remove necrotic tissue and fat; When subcutaneous suture, try to avoid the formation of dead space, and suture should not be too tight or too dense.

What should I do if there is fat liquefaction after operation?

If the incision doesn't crack, puncture and extract exudate from the cavity while dressing the wound every day, inject appropriate amount of prednisolone ointment, pressure bandage and give antibiotics to prevent secondary infection.

If the incision is cracked, remove the suture after local anesthesia, rinse the incision with metronidazole to remove necrotic tissue and excess fat, and gently fix the suture with adhesive tape in the middle of the wound. At the same time, the incision was coated with sugar, pressurized, and the gown and Elizabeth collar were worn.

It's best to clean and change the dressing once a day, and irradiate the incision with infrared rays for half an hour, and replenish energy, vitamin C, amino acids and other nutrients intravenously to speed up wound healing, and inject Sumono to prevent secondary infection.

I wish your cat a speedy recovery.
