Endoscopy Nursing Care
On this page
Direct answer
Left lateral position, mouthguard in place, pulse oximeter on, suction within reach — the upper GI endoscopy nurse has the patient's airway and the procedure's safety in her hands while the endoscopist watches the monitor. Endoscopy nursing covers pre-procedure preparation (identity and consent check, nil per mouth six hours or more for upper procedures, bowel preparation for colonoscopy, anticoagulant and diabetes management per protocol), intra-procedure care (positioning, sedation with midazolam and often fentanyl or propofol, continuous monitoring of saturation, ECG and blood pressure, oxygen supplementation), and recovery until discharge criteria are met, with an escort mandatory. Between cases comes the invisible half of the job: scope reprocessing — leak testing, manual cleaning, then high-level disinfection, classically 2 per cent glutaraldehyde immersion per the manufacturer's contact time — because a contaminated scope infects the next patient silently.
What you must remember
- Pre-procedure checklist: correct patient and procedure, signed informed consent, fasting status (at least 6 hours solids for upper GI endoscopy; colonoscopy needs completed purgative preparation and clear fluids only), allergy and anticoagulant history, dentures and jewellery removed, IV access secured.
- Sedation and monitoring: midazolam titrated (commonly 1 to 2.5 mg IV increments) with fentanyl 25 to 50 micrograms or propofol per provider; continuous pulse oximetry and ECG with intermittent blood pressure, oxygen and reversal agents — flumazenil, naloxone — immediately available.
- Positioning: left lateral for gastroscopy (aspiration protection, head supported, mouthguard secured); left lateral with knees flexed for colonoscopy; bronchoscopy semi-recumbent.
- Recovery and discharge criteria: vital signs stable and back to baseline, awake and oriented, able to swallow and walk (or pre-procedure baseline), accompanied by a responsible adult, given written post-sedation instructions (no driving, no legal decisions, no alcohol for 24 hours).
- Complication vigilance: perforation (severe pain, subcutaneous emphysema in neck or chest, tachycardia, later peritonitis) — declaring after the patient leaves the table; bleeding after biopsy or polypectomy (melena, haematemesis, falling haematocrit); oversedation with respiratory depression; post-ERCP pancreatitis (epigastric pain at 4 to 24 hours).
- Scope reprocessing sequence: leak test, immediate manual cleaning with enzymatic detergent and channel brushing, rinse, high-level disinfection (2 per cent glutaraldehyde immersion per validated contact time, commonly 20 to 45 minutes), alcohol flush and drying, then hanging storage with documentation — traceability per scope per patient; single-use accessories where mandated and duodenoscope-specific elevator-channel protocols.
A gastroscopy morning walked through
Mrs D, 52, is booked for gastroscopy at 0900 for dyspepsia with anaemia. At 0845 the nurse verifies identity, consent, last intake (nothing since 2200), warfarin and allergies; dentures out, mouthguard ready, the throat-spray explanation repeated (numb gag for an hour, no eating until it returns). Inside the room she positions her left lateral with head supported, gives oxygen by nasal prongs, and connects monitoring. Midazolam 2 mg and fentanyl 50 micrograms later she is drowsy but rousable; the nurse's eyes stay on the saturation, the airway and abdominal distension, not the monitor screen — her job is the patient, the endoscopist's is the image. Biopsies drop into labelled formalin jars, read aloud and confirmed. In recovery, observations run every 10 to 15 minutes until she is conversent; discharge happens only with a stable pulse, oriented conversation, a passed swallow of water, and her daughter as escort, with written advice on sore throat, late bleeding signs (black stools, vomiting blood, severe pain) and a number to call. The same nurse then reprocesses the scope — leak test, brush, disinfect, dry, log — before the next patient.
Where students slip in endoscopy questions
Examiners repeatedly catch two gaps: sedation is not anaesthesia, so the answer "the nurse monitors oxygen saturation, consciousness and airway throughout, with flumazenil and naloxone at the bedside" is expected — not "the anaesthetist handles it". Second, the complication question is almost always perforation, and the winning detail is timing and sign: severe pain with subcutaneous emphysema, hours after the procedure, commoner after therapeutic than diagnostic endoscopy. Vivas probe positioning rationale (left lateral prevents aspiration), colonoscopy preparation, and post-ERCP pancreatitis. Infection-control questions reward the full reprocessing sequence with the glutaraldehyde 2 per cent figure — an Indian endoscopy-suite staple — and duodenoscopes' extra elevator-channel attention. Indian framing: endoscopy volumes in district and private centres have grown hugely, making discharge criteria and escort rules the safety net examiners want stated.
Frequently asked questions
What preparation does a patient need before upper GI endoscopy?
Identity and consent verification, nil by mouth for at least 6 hours, medication and anticoagulant review per protocol, dentures removed, IV access, and an explanation including the throat spray.
How is a patient monitored during endoscopic sedation?
Continuous pulse oximetry and ECG with intermittent blood pressure, consciousness and airway assessment, oxygen, and reversal agents — flumazenil, naloxone — at the bedside.
What are the discharge criteria after sedation endoscopy?
Stable vital signs at baseline, awake and oriented, able to swallow and walk, accompanied by a responsible adult, and given written 24-hour restrictions (no driving or alcohol).
How is perforation after endoscopy recognised and handled?
Severe chest, neck or abdominal pain with subcutaneous emphysema and tachycardia; management is nothing by mouth, IV fluids, antibiotics and urgent surgical consultation.
Why is glutaraldehyde central to endoscope reprocessing?
Two per cent glutaraldehyde is the classic high-level disinfectant for flexible endoscopes after meticulous manual cleaning, with a validated immersion contact time; proper reprocessing prevents patient-to-patient transmission of pathogens.
