Plain-language summary
The aim of this prospective, randomized, pilot study is compare ease of tracheal intubation, amount of microaspiration and efficacy of secretion removal using three FDA (Food and Drug Administration)-cleared endotracheal tubes (ETT) after the induction of general anesthesia in the operating room (OR). Studies in the intensive care unit (ICU) have demonstrated a significant reduction in the incidence of ventilator acquired pneumonia when a ETT with suction above the cuff is used to remove secretions that accumulate above the inflated cuff. This will be the first study to evaluate the efficacy of above the cuff suctioning during general anesthesia and surgery.
One hundred and ten adult patients undergoing elective abdominal surgery (general, colorectal or gynecological) requiring general anesthesia with an endotracheal tube and mechanical ventilation will be randomized into 3 groups to receive one of the following three endotracheal tubes:
1. Teleflex ISIS HVT Cuffed Tracheal Tube with Subglottic Secretion Suction Port Endotracheal Tube (Teleflex ISIS ETT).
2. Mallinckrodt TaperGuard Evac Endotracheal Tube (TaperGuard Evac ETT).
3. Mallinckrodt Intermediate Hi-Lo Endotracheal Tube. (Standard ETT)
The first two groups will be compared to standard ETT (third group) regarding easy of tracheal intubation, efficacy of suctioning of secretions, efficacy of sealing the trachea with an inflated ETT cuff by preventing the movement of test dye (methylene blue) from the pharynx into the trachea and incidence of post-operative respiratory complications.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Scheduled for elective abdominal surgery with an anticipated duration longer than 2 hours.
* ASA (American Society of Anesthesiologists) Physical status Classification 1 to 3. (1 - normal healthy patient, 2 - patients with mild systemic disease, 3 - patients with severe systemic disease)
* Endotracheal intubation anticipated to be routine (not difficult) based upon preoperative airway assessment
Exclusion Criteria:
* Short duration surgery (anticipated \< 2 hours) or emergency (non-elective) surgery
* ASA Physical status Classification 4 to 5. (4 - patients with severe systemic diseases that is a constant threat to life, 5 - Moribund patients who are not expected to survive without the operation)
* Anticipated difficult airway requiring technique other than direct laryngoscopy for intubation of the trachea.
* Pregnancy
* History of allergic reaction to Methylene Blue medication
* Methemoglobinemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency
* History of symptomatic chronic obstructive pulmonary disease (asthma, bronchitis, emphysema) or recent pneumonia (\< 6 months prior to surgery).
* Hypoxemia (hemoglobin oxygen saturation \< 90% room air or on O2 at home or in hospital)
* History of coagulopathy, IV heparin therapy, or coumadin therapy (INR \> 2.5)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
