Surgical Services

Stratham-Newfields Veterinary Hospital is voluntarily evaluated on 900 quality standards by the American Animal Hospital Association (AAHA). Many of these standards pertain to the safety and quality of our surgical care and pain management practices.

Our Human-Grade Surgical Facilities: SNVH is equipped with state-of-the-art surgical facilities to provide your pet with the safety of a human-grade operating environment.

Stratham-Newfields Veterinary Hospital has two separate surgery rooms to decrease the risk of infection. (Most veterinary hospitals cut corners by having multiple tables in one room, which puts your pet at greater risk for post-surgical infections.)
  • Our surgery rooms have human-hospital grade HEPA filtration which performs a complete air exchange every four minutes to reduce risk of surgical infections and increase safety.
  • Additionally, our filtration system maintains a positive pressure. This causes the air to always flow out of the surgery room when the door is opened, which makes it nearly impossible for contaminants to enter the surgical field.

Preoperative Exam
​& Blood Work

Your veterinarian at SNVH will give your pet a thorough physical examination the morning of the procedure to make sure he/she is healthy enough for the surgery and anesthesia. 

We check a complete blood count (CBC), blood sugar, liver and kidney values, and a complete biochemical profile of 25+ components including electrolytes. If the blood work is normal, we can proceed with confidence knowing the anesthetic risk is minimized.

Patient Monitoring

Stratham-Newfields Veterinary Hospital uses the most up-to-date pain management protocols, advanced monitoring equipment, and the safest anesthesia available. At SNVH, a Credentialed Veterinary Technician is dedicated exclusively to carefully monitoring your pet from the moment anesthesia is administered until your pet is recovered and awake. 

In addition, we continuously electronically monitor your pet, including: 
  • Heart (EKG)
  • Arterial Oxygen Level (spO2)
  • End-Tidal Carbon Dioxide
  • Core Temperature
  • Respiration 
  • Blood Pressure
  • Computer Controlled Ventilator Anesthesia machine (enables precise controlled inhalant drug administration)

Endotracheal Tubes (Breathing Tubes)

We use a new, sterile trach tube for your pet. Every time.
How safe is your pet's breathing tube?
  • Many vet practices re-use their disposable endotracheal tubes (the "breathing tube" that goes into your pet's windpipe) to reduce costs.
  • Not only are re-used tubes no longer sterile, reuse risks failure of the seal, which could allow fluid to enter your pet's lungs during the procedure.
  • At SNVH, your pet will always get a new, sterile endotracheal tube.
