Objective: Advancement of the endotracheal tube through a fibreoptic scope can sometimes prove to be challenging in obese patients. The Parker Flex-Tip endotracheal tube was developed with a curved and tapered distal tip to facilitate easier placement in the trachea. This study examined the use of the Parker Flex-Tip tube as compared to standard endotracheal tubes in patients with a body mass index of 30 or greater.
Methods: Sixty patients undergoing surgery requiring general anaesthesia were randomised into two groups. Using the fibreoptic scope, one group was intubated with the Parker Flex-Tip tube and the other group with a standard polyvinyl Portex tube. The time for intubation and the number of attempts required to place the endotracheal tube were measured and recorded.
Results: Using the Mann-Whitney U rank sum test, the median time needed for intubation with the two types of endotracheal tubes did not show a significant difference. The chi-square analyses were conducted for the number of attempts needed to place the endotracheal tubes, which also did not demonstrate any significant difference.
Conclusions: Parker Flex-Tip endotracheal tube was not superior to the standard endotracheal tubes for fibreoptic intubation in obese patients.

Background: Advancing a tracheal tube over a tracheal tube exchanger into the trachea frequently causes difficulties because of the tube impingement on laryngeal structures. In the present study, we measured the resistance of tube advancement both objectively and subjectively with a variety of combinations of tube exchanger sizes and tracheal tubes using a manikin simulator.

Article Synopsis
- The study aimed to evaluate the risk of incomplete sealing in tracheal diverticula during intubation with different tracheal tubes, particularly focusing on tube fixation when the tube's vocal cord guide overlaps the patient’s vocal cord.
- Researchers analyzed thoracic CT scans of patients from January 2018 to July 2020 and assessed three different tracheal tube designs for their effectiveness in sealing tracheal diverticula and avoiding bronchial intubation.
- Results indicated that while tubes with longer lengths had a lower risk of incompletely sealing diverticula and bronchial intubation, no tube successfully met the requirements for both outcomes, raising concerns about tube fixation practices.

Background: Despite reported superior intubation outcomes associated with Parker Flex-Tip (PFT) tubes compared with those associated with standard polyvinylchloride tubes, the efficacy and safety of PFT tubes remain uncertain.
Objectives: To compare the intubation outcomes between PFT and conventional standard polyvinylchloride tubes.
Design: Meta-analysis of randomised controlled trials.

Introduction: The choice of endotracheal tube (ETT) is important for successful orotracheal fibreoptic intubation (OFI). The aim of this study was to compare the use of the Parker flex tip (PFT) with the unoflex reinforced (UFR) ETT during OFI.
Material And Methods: A total of 58 patients who underwent elective surgery under general anaesthesia were randomised to two ETT groups, the PFT group (n = 29) and the UFR group (n = 29), for OFI in simulated difficult intubation patients using a rigid cervical collar.
