Premedication is using medication before some other therapy (usually surgery or chemotherapy) to prepare for that forthcoming therapy.Typical examples include premedicating with a sedative or analgesic before surgery; using prophylactic (preventive) antibiotics before surgery; and using antiemetics or antihistamines before chemotherapy.
Depending on the type of surgery and anticipated contamination associated with it, combinations of different agents or different routes of administration (e.g. intravenous and oral antibiotics) might be beneficial in reducing perioperative adverse events. [6] [7] For prophylaxis in surgery, only antibiotics with good tolerability should be used.
Since polyps often take 10 to 15 years to transform into cancer in someone at average risk of colorectal cancer, guidelines recommend 10 years after a normal screening colonoscopy before the next colonoscopy. (This interval does not apply to people at high risk of colorectal cancer or those who experience symptoms of the disease.) [28] [29]
For non-emergent procedures, patients are typically instructed to follow a clear liquid diet or fast and take a mechanical bowel preparation (oral osmotic agents or laxative) to clear the bowels before surgery. [4] [1] Antibiotics may also be prescribed ahead of surgery to reduce risk of post-operative infection. [2]
At some point before surgery a health care provider conducts a preoperative assessment to verify that a person is fit and ready for the surgery. [ 1 ] [ 2 ] For surgeries in which a person receives either general or local anesthesia, this assessment may be done either by a doctor or a nurse trained to do the assessment. [ 2 ]
Although perforation generally requires surgery, certain cases may be treated with antibiotics and intravenous fluids. Bleeding may occur at the site of a biopsy or polyp removal. Such typically minor bleeding may simply stop on its own or be controlled by cauterisation. Seldom does surgery become necessary.
Before the procedure, the physician might ask the patient to stop taking certain medications including blood thinners, aspirin, diabetes medications, or nonsteroidal anti-inflammatory drugs. A bowel prep is usually taken the night before and into the morning of the procedure which consists of an enema or laxatives , either pills or powder ...
Prophylactic surgery (also known as preventive surgery or risk-reducing surgery) is a form of surgery most commonly intended to minimize or eliminate the risk of a patient developing cancer in an organ or gland before development occurs. This is a life-saving procedure for those at high risk of developing cancer in certain organs.
