Cold vs. Hot snare
Before a hot snare polypectomy, the nurse must confirm these key steps related to the dispersive (grounding) pad.
What is verifying that the pad is correctly applied, fully adherent, and connected to the generator?
This is the general electrosurgical mode often used on ERBE units for standard hot snare polypectomy of small lesions.
What is EndoCut (blended cutting with coagulation)?
The concentration of epinephrine used for bleeds
What is 1:10,000
During a sedated colonoscopy, standard monitoring performed by the nurse includes at least these two vital parameters.
What are pulse oximetry and blood pressure (plus heart rate and respiratory rate)?
After removal of a small polyp, a few streaks of blood in the stool for a day or two are usually described to patients this way.
What is “generally expected and mild”?
The ideal site for grounding pad placement in colonoscopy is this type of area on the body.
What is a clean, dry, hair-free, well‑vascularized muscular area such as the flank?
Two types of probes used for Argon (APC)
What are straight and circumferential probes.
Name of the endoscopic hemostasis system (powder) for stopping gastrointestinal bleeding
Device measures carbon dioxide (CO2) in exhaled breath
What is Capnography
Nurses must tell patients to seek urgent care if they develop this type of bleeding after polypectomy.
What is heavy or ongoing bleeding, clots, maroon or dark blood, or feeling light‑headed or dizzy?
Grounding pads placed over scar tissue, bony prominences, or moist, oily skin increase the risk of this electrosurgical complication.
What is a patient skin burn at the pad site?
The Coagulation settings for Gold Probe (Bipolar) in endoscopy
15-20 watts
A patient becomes more deeply sedated and snoring loudly during polypectomy. The nurse’s first action should be this intervention.
What is repositioning the airway (e.g., chin lift/jaw thrust) and reassessing breathing?
Endoscopy sedation guidelines emphasize documenting these three sedation-related items before discharge.
What are stable vital signs, return to baseline mental status, and adequate pain/nausea control?
Worsening abdominal pain with fever, shivering, or a fast heart rate after polypectomy may signal this serious complication.
What is perforation?
What is the mode for Fuji colonoscopes that helps identify polyps?
What is LCI (Linked colour imaging)
These are the standard settings on the ERBE for hot snare?
Cut (watt) and Effect
Coag (watt) and Effect
What is
Cut Effect 3 / 40 Watt
Coag Effect 2 / 25 Watt
Good visualization and polyp detection are improved when the nurse actively assists with these two bedside maneuvers during colonoscopy.
What are patient repositioning and application of targeted abdominal pressure?
The Mallampati score when there is only visualization of the base of the uvula
What is Class 3
Because delayed post‑polypectomy bleeding can occur up to about this long after the procedure, nurses should include this timeframe in discharge teaching.
What is up to about 2–3 weeks (and especially the first 5–14 days)?
