Bowel Preparation: Nursing Assessment, Patient Education, and Evidence-Based Perioperative Management
Abstract
Background: Bowel preparation is essential for high-quality colonoscopy, enabling accurate mucosal visualization and reducing missed lesions. Inadequate cleansing compromises diagnostic reliability, increases procedural risks, and necessitates repeat examinations.
Aim: To review nursing roles in bowel preparation, focusing on assessment, patient education, and evidence-based perioperative management to optimize outcomes.
Methods: This narrative review synthesizes current evidence on bowel preparation regimens, contraindications, risk factors, and nursing interventions. It examines pharmacologic classifications (isosmotic, hypoosmotic, hyperosmotic), dosing strategies, and interprofessional collaboration.
Results: High-volume polyethylene glycol (PEG) remains the safest option for complex patients, while low-volume PEG with ascorbic acid improves tolerability but requires caution in G6PD deficiency. Sulfate-free PEG enhances palatability without compromising efficacy. Hyperosmotic agents (magnesium citrate, sodium sulfate) and sodium phosphate carry significant risks, particularly in renal impairment and electrolyte imbalance. Split-dose regimens consistently outperform single-dose schedules in cleansing quality and adenoma detection. Nursing interventions—risk assessment, education reinforcement, hydration monitoring, and early escalation for intolerance—are pivotal for success.
Conclusion: Effective bowel preparation is a structured, team-based process integrating individualized regimen selection, patient-centered education, and vigilant nursing oversight. Optimizing preparation quality improves diagnostic accuracy, reduces repeat procedures, and enhances patient safety.
