Introduction
Standard Framework and Technology Evolution
As my country's first national standard for companion animal sterilization surgery, GB/T40449-2021 fills the gap in technical operation specifications in the field of pet medicine. The standard was formulated by the National Companion Animal Standardization Technical Committee (SAC/TC541) and integrates the clinical practice experience of 9 institutions including the Beijing Small Animal Diagnosis and Treatment Industry Association.
Definition of core terms
| Terms | Definition | Scope of surgery |
|---|---|---|
| Neuter and neuter male dogs/cats | Orchiectomy | Scrotal or midline abdominal incision |
| Neuter and neuter female dogs/cats | Ovariectomy | Midline abdominal incision behind the umbilicus |
| Management of cryptorchidism | Requires special positioning for removal | Included in the mandatory preoperative inspection items |
Key points of preoperative preparation
Four elements of health check: medical history investigation + physiological index detection + blood test + testicular palpation. The fasting time of young animals is shortened to 4-8 hours, reflecting the principle of age-differentiated treatment.
Instrument sterilization requirements: Clearly lists the disinfection standards for 11 types of surgical instruments, including easily overlooked instruments such as towel forceps.
Comparison of surgical differences between male dogs and cats
| Parameters | Male cats | Male dogs |
|---|---|---|
| Incision location | Bottom of scrotum | Anterior ventral midline of scrotum |
| Spermatic cord management | Double ligation + self-knotting method | Conventional double ligation |
| Wound suturing | Optional | Must suturing |
Main surgical techniques for female dogs and cats
Incision positioning: The incision range for dogs is 3-10cm, while for cats it is strictly controlled at 0.5-3cm, reflecting the anatomical differences of species. The uterine artery and vein need to be double ligated to prevent bleeding.
Implementation recommendations
- Establish a standardized surgical kit to ensure that all instruments are available
- Laparoscopy is recommended for cases of cryptorchidism
- Use an Elizabethan collar to prevent licking and biting within 3 days after surgery
- Regular follow-up visits to monitor wound healing
