Title: Enhancing Surgical Safety in Veterinary Medicine: The Importance of Surgery Checklists.

Introduction: Surgical procedures in veterinary medicine are intricate processes that demand meticulous coordination among the surgical team. Despite the significant risks involved, using surgery checklists in veterinary surgery remains uncommon. This lecture explores the importance of implementing surgery checklists in veterinary medicine, highlighting their benefits, the role of teamwork, the influence of the World Health Organization (WHO) guidelines, the structure of the checklist, and the impact of checklist implementation on veterinary professionals.

The Value of Surgery Checklists: Surgery is a collaborative effort that involves various professionals, including surgeons, anesthesia specialists, nurses, and technicians. The entire team should embrace surgery checklists to ensure a safe and efficient surgical environment. These checklists offer a systematic approach to enhancing patient safety by reducing the likelihood of errors, complications, and avoidable risks.

The Influence of the World Health Organization: The World Health Organization’s “Safe Surgery Saves Lives” initiative has pioneered surgery checklists as a vital tool to improve patient outcomes. While initially developed for human surgery, the principles apply equally to veterinary medicine. This initiative emphasizes the need for adherence to essential safety steps that minimize common and preventable surgical risks.

Structure of the Surgery Checklist: The surgery checklist, designed to be concise and straightforward, divides the surgical procedure into four phases, each corresponding to a specific time period in the surgical workflow:

1. Sign In: Before induction of anesthesia

2. Move-In: Before patient movement in the operating room

3. Time Out: Before surgical incision

4. Sign Out: During or after wound closure but before patient removal from the operating room

Each phase involves a checklist coordinator who verifies the completion of tasks before progressing to the next stage. This structured approach ensures that critical safety steps are consistently followed.

Benefits of Checklist Implementation: A survey of veterinary professionals (VSSO listserve) revealed that a significant percentage (67%, n= 48) already used surgery checklists, while others had not adopted this practice. However, we observed that many of the individual steps in the checklist were already considered routine in facilities globally, albeit often not followed comprehensively. This underscores the need for implementing surgery checklists to ensure consistency and adherence to these vital safety measures.

Impact on Veterinary Professionals: The follow-up survey results provide insights into the impact of checklist implementation on veterinary professionals. The findings suggest that surgery checklists improve communication, reduce work pressure, enhance teamwork, and better training. Most professionals felt comfortable asking questions when something was amiss and believed that patient care information was communicated effectively. However, there were still concerns about missing critical information when needed, indicating room for improvement. Moreover, the survey revealed that teamwork and training improved after checklist implementation, with a substantial percentage feeling that their facility did a good job communicating information affecting patient care. Issues such as feeling rushed while caring for patients, and the adequacy of orientation and refresher training for new staff require attention.

Conclusion: In conclusion, implementing surgery checklists in veterinary medicine ensures patient safety and minimizes avoidable risks. The World Health Organization’s emphasis on safe surgery has paved the way for adopting surgery checklists, which offer a structured approach to enhancing communication, teamwork, and training among veterinary professionals. The survey results underscore the benefits of checklist implementation while highlighting areas requiring further attention. As the WSAVA Oncology Working Group prepares to launch the WoW Cancer Surgery Checklist, the veterinary community can enhance surgical safety and patient outcomes through comprehensive surgery checklists.

Hyperthyroidism in cats

Thyroid hyperplasia in cats, known as hyperthyroidism, is a common endocrine disorder. It occurs when the thyroid glands produce an excessive amount of thyroid hormones. This often results in an increase in metabolic rate and a range of symptoms, including weight loss despite increased appetite, restlessness, increased heart rate, vomiting, diarrhea, and sometimes changes in behavior. The exact cause of feline hyperthyroidism is not fully understood, but it’s thought to be related to changes in the thyroid gland’s structure. Most cases are caused by benign tumors called thyroid adenomas, which cause the thyroid gland to enlarge and overproduce hormones. In rare cases, thyroid carcinomas (malignant tumors) can also cause hyperthyroidism. Diagnosis is typically made through blood tests that measure the levels of thyroid hormones (T3 and T4).

Feline hyperthyroidism can be treated through various methods, depending on the cat’s age, overall health, and the preferences of both the cat owner and the veterinarian. Here are the common treatment options:

1. **Medication**: Anti-thyroid medications, such as methimazole or carbimazole, are commonly prescribed. These medications help to control the overproduction of thyroid hormones. However, they require ongoing administration and monitoring of thyroid levels.

2. **Radioactive Iodine Therapy**: This treatment involves administering a small, controlled amount of radioactive iodine, which selectively targets and destroys the overactive thyroid tissue. It’s considered a very effective treatment, often resulting in a permanent resolution of hyperthyroidism. Cats receiving this treatment are usually hospitalized briefly to ensure proper handling of radioactive material.

3. **Surgical Removal of the Thyroid Glands**: Surgical removal of the affected thyroid gland(s) can be an option, especially if only one gland is affected or the cat is not suitable for radioactive iodine treatment. However, surgery carries risks and may require life-long hormone supplementation if both glands are removed.

4. **Prescription Diet**: Some specialized diets (Hill’s Prescription Diet y/d) are formulated to manage hyperthyroidism. These diets are low in iodine, essential for thyroid hormone production. Restricting iodine intake reduces the thyroid’s ability to produce excess hormones.

Treatment choice depends on factors like the cat’s age, overall health, the severity of the hyperthyroidism, and the owner’s preferences. If left untreated, hyperthyroidism can lead to severe complications such as heart problems, kidney issues, and high blood pressure. Regular veterinary check-ups and early detection are important for managing this condition effectively.

VetGirl U Lectures

It was so awesome to give 6 lectures at VetGirl U! I just had the best time, here are some of my fav pics

On a serious note, I talked about wound management and specifically the use of honey in wound healing. I was referencing a specific article:

Which showed us that after a thorough review there is not enough good research to support its use in cats and dogs. I also have incidental evidence that it worked on some cases but we really need to do some good and independent research. Interesting was that most articles came from Iran or Malaysia! BTW there is some great research in mice and rats, but if a cat is not a dog, dogs&cats are definitely not mice or rats.

Gall bladder mucocele

Dr Jaffey at VetGirlU

A great lecture from Dr. Jaffey at VetGirl Uni. He says that we are all accustomed to the kiwi pattern. The “kiwi pattern” is associated with gallbladder mucoceles in dogs. Gallbladder mucoceles are often visualized on ultrasound with a central anechoic area surrounded by a thickened, echogenic wall, resembling a kiwi fruit. This pattern can be indicative of mucous accumulation within the gallbladder. However there are truly 6 patterns and most do not look like a kiwi at all.

VI looks like a kiwi!!!

Treatment of acutely sick dogs:
Cholecystectomy is recommended in majority of cases regardless of the severity of signs. Always check for biliary obstruction during the surgery

If you can not do surgery, you can try medical therapy including urosdiol, a low fat diet and broad spectrum antibiotics.

  • Ursodiol
  • Broad-spectrum antibiotics
  • Other supportive care therapy varies case-by-case


For dogs without clinical signs you either need to keep a very close eye on it with multiple evaluations or take them out prophylactically. Prophylactic cholecystectomy is a procedure with less than 5 percent complication rate and can even be done laparoscopically if the gallbladder is not too big.

Thank you Dr. Jaffey

Dr. Natalie Marks

Just arrived in Scottsdale Arizona where I am speaking at VetGirl Uni. Currently I am listening to the excellent Dr. Natalie Marks talking about hypoglycemia. Do you know what the most common causes are?

Common causes are: 1. Sepsis; 2. Tumors outside of the pancreas; 3. Liver disease; 4. Hypoadrenocorticism; 5. Insulinoma 6. Iatrogenic (too much insulinoma).

This is a great conference! Put it on your todo list for next year!
