Medicine in ancient Rome was highly influenced by ancient Greek medicine, but also developed new practices through knowledge of the Hippocratic Corpus combined with use of the treatment of diet, regimen, along with surgical procedures. This was most notably seen through the works of two of the prominent Greek physicians, Dioscorides and Galen, who practiced medicine and recorded their discoveries. This is contrary to two other physicians like Soranus of Ephesus and Asclepiades of Bithynia, who practiced medicine both in outside territories and in ancient Roman territory, subsequently. Dioscorides was a Roman army physician, Soranus was a representative for the Methodic school of medicine, Galen performed public demonstrations, and Asclepiades was a leading Roman physician. These four physicians all had knowledge of medicine, ailments, and treatments that were healing, long lasting and influential to human history. Medicine in Ancient Rome was one of the most important influences to the modern medicine we have now.

Ancient Roman medicine was divided into specializations such as ophthalmology and urology. To increase their knowledge of the human body, physicians used a variety of surgical procedures for dissection that were carried out using many different instruments including forceps, scalpels and catheters.

A surgeon's assistant, also known as a surgical assistant, assistant in surgery or first assistant, is a healthcare professional who provides direct manual and/or instrumental assistance to meet the in-procedure demands of a surgeon during a surgical operation. Most surgical assistants are trainee surgeons or junior doctors, but In the United Kingdom, a surgical care practitioner, who is not a qualified doctor, may perform simple surgical operations under the supervision of one.

In the United States, the American College of Surgeons supports the concept that, ideally, the first assistant at the operating table should be a qualified surgeon or a resident in an approved surgical training program. Residents who have appropriate levels of training should be provided with opportunities to assist and participate in operations. If such assistants are unavailable, other physicians who are experienced in assisting may participate or a qualified practitioner licensed in the role of surgical assistant. The American College of Surgeons maintains that a physician who assists with an operation should be trained to participate in and actively assist the surgeon in safely completing the operation. When a surgeon is unavailable to serve as an assistant, a qualified surgical resident or other qualified health care professional, such as a nurse practitioner or physician assistant with experience in assisting, may participate in operations, according to the ACS Statements on Principles. A qualified practitioner is defined as any licensed practitioner with sufficient training to conduct a delegated portion of a procedure without the need for more experienced supervision, according to the ACS Statements on Principles. The U.S. Bureau of Labor defines surgical assistants as individuals that assist in operations, under the supervision of surgeons. They may, in accordance with state laws, help surgeons to make incisions and close surgical sites, manipulate or remove tissues, implant surgical devices or drains, suction the surgical site, place catheters, clamp or cauterize vessels or tissue, and apply dressings.

Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. It is frequently performed in critically injured, ill, or anesthetized patients to facilitate ventilation of the lungs, including mechanical ventilation, and to prevent the possibility of asphyxiation or airway obstruction.

The most widely used route is orotracheal, in which an endotracheal tube is passed through the mouth and vocal apparatus into the trachea. In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for airway support is anticipated.

A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent airway and to ensure the adequate exchange of oxygen and carbon dioxide.

Many different types of tracheal tubes are available, suited for different specific applications:

Minimally invasive procedures (also known as minimally invasive surgeries) encompass surgical techniques that limit the size of incisions needed, thereby reducing wound healing time, associated pain, and risk of infection. Surgery by definition is invasive, and many operations requiring incisions of some size are referred to as open surgery. Incisions made during open surgery can sometimes leave large wounds that may be painful and take a long time to heal. Advancements in medical technologies have enabled the development and regular use of minimally invasive procedures. For example, endovascular aneurysm repair, a minimally invasive surgery, has become the most common method of repairing abdominal aortic aneurysms in the US as of 2003. The procedure involves much smaller incisions than the corresponding open surgery procedure of open aortic surgery.

Interventional radiologists were the forerunners of minimally invasive procedures. Using imaging techniques, radiologists were able to direct interventional instruments through the body by way of catheters instead of the large incisions needed in traditional surgery. As a result, many conditions once requiring surgery can now be treated non-surgically.

Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method of medication administration in which a medicine is injected into the epidural space around the spinal cord. The epidural route is used by physicians and nurse anesthetists to administer local anesthetic agents, analgesics, diagnostic medicines such as radiocontrast agents, and other medicines such as glucocorticoids. Epidural administration involves the placement of a catheter into the epidural space, which may remain in place for the duration of the treatment. The technique of intentional epidural administration of medication was first described in 1921 by the Spanish Aragonese military surgeon Fidel Pagés.

Epidural anaesthesia causes a loss of sensation, including pain, by blocking the transmission of signals through nerve fibres in or near the spinal cord. For this reason, epidurals are commonly used for pain control during childbirth and surgery, for which the technique is considered safe and effective, and is considered more effective and safer than giving pain medication by mouth or through an intravenous line. An epidural injection may also be used to administer steroids for the treatment of inflammatory conditions of the spinal cord. It is not recommended for people with severe bleeding disorders, low platelet counts, or infections near the intended injection site. Severe complications from epidural administration are rare, but can include problems resulting from improper administration, as well as adverse effects from medicine. The most common complications of epidural injections include bleeding problems, headaches, and inadequate pain control. Epidural analgesia during childbirth may also impact the mother's ability to move during labor. Very large doses of anesthetics or analgesics may result in respiratory depression.

Ancient Roman surgical practices developed from Greek techniques. Roman surgeons and doctors usually learned through apprenticeships or studying. Ancient Roman doctors such as Galen and Celsus described Roman surgical techniques in their medical literature, such as De Medicina. These methods encompassed modern oral surgery, cosmetic surgery, sutures, ligatures, amputations, tonsillectomies, mastectomies, cataract surgeries, lithotomies, hernia repair, gynecology, neurosurgery, and others. Surgery was a rare practice, as it was dangerous and often had fatal results. To perform these procedures, they used tools such as specula, catheters, enemas, bone levers, osteotomes, phlebotomes, probes, curettes, bone drills, bone forceps, cupping vessels, knives, scalpels, scissors, and spathas.
