Purpose: Novel designs of the endotracheal tube (ETT) are emerged to reduce the risk of ventilator-associated pneumonia (VAP). We evaluated the effect of two different types, namely silver-coated (Bactiguard) and subglottic suctioning (Taperguard) ETTs, on the incidence of VAP in critically-ill patients.
Methods: A total of 90 patients, mechanically ventilated for >72 h, were randomly assigned to Bactiguard and Taperguard groups. They otherwise received routine care, including VAP prevention measures during their intensive care unit (ICU) stay. Subglottic suctioning was performed in Taperguard group. Statistical analyses were performed using SPSS 25 for iMacs.
Results: Both groups had similar demographics and did not differ in the prevalence of comorbidities and the severity of underlying illness. There was no difference in the frequency of reintubation (P = .565), the duration of ventilation, ICU and total hospital length of stay. VAP developed in 31% of the Bactiguard group and 20% of the Taperguard group (P = .227). Nearly twice the number of patients died in the Bactiguard group compared to the Taperguard group. This difference was not significant either (P = .352).
Conclusions: The use of Bactiguard or Taperguard ETTs was not associated with any difference in the incidence of VAP or ICU mortality.

Aim: To assess the difference between endotracheal tubes (ETT) with continuous suction of subglottic secretions (CASS) and standard ETT in preventing secretions movement from the pharynx into the trachea, past the inflated cuff during general anesthesia.
Methods: This randomized, controlled trial enrolled 50 patients who underwent general anesthesia for elective abdominal surgery lasting longer than two hours. They received either ETT with CASS: Teleflex ISIS HVT (GISIS, n=17) or Mallinckrodt TaperGuard Evac (GEvac, n=17), or ETT without suction: Mallinckrodt Intermediate Hi-Lo (GStand, n=16).

Background: The proper cuff pressure of endotracheal tube (ET) plays an important role in sealing the airway and preventing airway complications during mechanical ventilation. The ET cuff shape affects the cuff pressure after positional change.
Aim: To investigate cuff pressure between tapered and cylindrical cuff after extension of head and neck during nasal endotracheal intubation.

Background: Endotracheal tube (ETT) with a tapered-shaped cuff had an improved sealing effect when compared to ETTs with a conventional cylindrical-shaped cuff. Positional change and neck movement typically displace an ETT and change the intracuff pressure. The aim of the current study was to compare the ETT cuff pressure in the TaperGuard ETT vs the conventional ETT after a change from the supine, neutral position to the extension of the neck and semi-Fowler position for thyroid surgery.

Background: Maintaining optimal intracuff pressure of the endotracheal tube is important during airway management. Rotation of the head can affect the cuff pressure of the endotracheal tube. We investigated the change in cuff pressure and the degree of tube displacement according to the direction of head rotation (toward the same side vs opposite side of tube fixation) using a TaperGuard endotracheal tube.
