Pre-Op Testing

Flu-Symptoms

Pre-op Testing

Medical consultants are generally asked to assess preoperative risk in most patients who are to undergo surgery. Even if you are a relatively healthy person, pre-op testing and laboratory is often necessary if you are to undergo an elective surgical procedure. A general systems examination should identify obvious abnormalities:

  • Cardiovascular system – heart murmur. With the exception of emergency surgery, patients should be hemodynamically stable and their vital signs normal before starting anesthesia
  • Respiratory system – abnormal breath sounds
  • Gastrointestinal system – abdominal masses, previous scars
  • Musculoskeletal system – skeletal malformations such as kyphoscoliosis
  • General – local skin infection

PREOPERATIVE TESTS

Routine preoperative testing (preoperative screening) of healthy people undergoing elective surgery is not recommended. Instead, a selective strategy, as outlined above, is safe and cost-effective as long as a complete medical history and physical examination are obtained. Based on the available evidence, our primary care doctors and healthcare professionals recommend the following preoperative tests:

  • Hemoglobin level for major surgery with significant expected blood loss or in patients 65 years or older
  • Serum creatinine level for people older than 50 years
  • Pregnancy testing in all reproductive age-group women
  • ECG in patients undergoing high-risk surgery (eg, vascular surgery) or intermediate-risk surgery and with at least one risk factor
  • CXR in patients older than 60 years

Gerardo C. Perez, D.O​

Doctor

Born in Cuba, Dr. Perez immigrated to the United States as a young boy, settling in New Jersey with his family. He attended Long Island University and earned a Bachelor of Science, while majoring in both Biology and Chemistry. In 1984, Dr. Perez graduated from the University of Medicine and Dentistry of New Jersey. He completed his family practice residency at Southeastern Medical Center in Miami and received his board certification in Family Medicine. Shortly after starting his private practice in 1987, Dr. Perez qualified and passed his Geriatric Board exam, an area of medicine that had always interested him and one that he felt was under-represented in the community. His interest in treating the older patient population stems from the extensive size of his family and the many experiences he had as a young man with his older relatives. 

For the past 30 years, Dr. Perez has proudly served the Hialeah-Miami Lakes community with the best quality and personal care available. His approach remains the same, “Keep it simple, and don’t over medicate.” He is a strong believer in preventative care and feels that nutrition and exercise are the best forms of medication. He tries to set an example for his patients in the way he cares for his own health.

Dr. Perez has been married to his wife Madeline for 27 years and has three sons, whom he credits for keeping him young and on his toes. Dr. Perez has coached travel baseball for many years, loves to landscape and is a culinarian. His latest interest, and one that he says stimulates him both physically and mentally, is Brazilian Jiu Jitsu.
