Predictors of Clinically Relevant Hypotension and Hypoxemia During Propofol-Based Diagnostic Gastrointestinal Endoscopy (PRO-GI SAFE)

Descrição detalhada
Propofol is widely used for diagnostic gastrointestinal endoscopy because of its rapid onset and recovery profile, but it may be associated with cardiopulmonary adverse events, particularly hypotension and hypoxemia. The reported incidence of these events varies substantially across studies because of differences in patient populations, definitions, monitoring intensity, and sedation/anesthesia practice.
This single-center prospective cohort study will enroll adult patients undergoing diagnostic gastrointestinal endoscopy with propofol as the primary sedative/anesthetic agent. Eligible participants will be consecutively recruited at Bach Mai Hospital. Baseline demographic characteristics, comorbidities, airway assessment findings, obstructive sleep apnea risk, procedural characteristics, and sedation/anesthesia-related variables will be collected using a standardized case report form.
The two co-primary outcomes are clinically relevant hypotension and clinically relevant hypoxemia during the peri-procedural period. Participants will be monitored from pre-procedure baseline through the procedure and until discharge from the recovery area. If early post-procedure observation is prolonged because of a sedation/anesthesia-related event, follow-up for that participant will continue until initial stabilization and an immediate post-procedure management decision are completed.
Two separate multivariable logistic regression models will be developed to identify independent predictors of clinically relevant hypotension and clinically relevant hypoxemia. The study is intended to inform risk stratification and improve patient safety during propofol-based diagnostic gastrointestinal endoscopy

Cohort Description
Adult patients undergoing diagnostic esophagogastroduodenoscopy, diagnostic colonoscopy, or combined diagnostic upper and lower gastrointestinal endoscopy with propofol as the primary sedative/anesthetic agent at a tertiary referral hospital.
All enrolled participants will receive standard peri-procedural monitoring and will be followed from pre-sedation assessment through discharge from the recovery area.
If early post-procedure observation is prolonged because of a sedation-related cardiopulmonary event, follow-up for that participant will continue until initial stabilization and an immediate post-procedure management decision are completed.
|
Propofol is the primary sedative/anesthetic agent used for diagnostic gastrointestinal endoscopy according to routine clinical practice.
The loading dose, incremental bolus doses, maintenance infusion rate if used, total dose, weight-normalized total dose, timing of administration, and any adjunct sedative or analgesic medications will be recorded as observational exposure variables.
Diagnostic gastrointestinal endoscopy includes esophagogastroduodenoscopy, colonoscopy, or combined diagnostic upper and lower gastrointestinal endoscopy performed without therapeutic intervention.
