Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In our study, we aim to compare the efficacy and ease of placement of Arndt and Tappa blocker for pediatric one lung ventilation. Our primary outcome is the time from laryngoscopy to successful insertion of the bronchial blocker by an experienced anaesthetist. Secondary outcomes are effects of two different bronchial blockers on lung isolation score, ease of placement of the bronchial blocker, mechanical ventilation parameters (tidal volume, respiratory rate, peak airway pressure, plateau pressure, compliance), intraoperative blood gas analysis (paO2, pCO2, saO2, lac), frequency of malposition after successful blocker placement, surgical exposure and complications. The difficulty of placement of the blocker will be assesed by a 5-point scale (1:very easy, 5:impossible) and the lung collapse will be evaluated by using a 10-point scale (10: complete collapse).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Tappa Blocker Group
After orotracheal intubation, Tappa endobronchial blocker will be inserted using a broncoscope by an experienced anaesthetist. Time from laryngoscopy to successful placement of the endobronchial blocker will be recorded.
Tappa Endobronchial Blocker
After intubation, the Tappa bronchial blocker will be advanced either through the intubation tube or outside the tube using a fiberoptic broncoscope. Once the position of the blocker is confirmed, the cuff of the blocker will be inflated with 1-3 mL of air. Since Tappa blocker has an autoinflation system, the anaesthetist can both inflate the cuff with one hand and operate the fiberoptic broncoscope at the same time.
Arndt Blocker Group
After orotracheal intubation, Arndt endobronchial blocker will be inserted using a broncoscope by the experienced anaesthetist. Time from laryngoscopy to successful placement of the endobronchial blocker will be recorded.
Arndt Endobronchial Blocker
After intubation, the endobronchial blocker will be passed through a multiport airway adapter that is placed at the proximal end of the tracheal tube.The fiberoptic broncoscope will be passed through the port and then through the guidewire loop at the end of the blocker. The bronchial blocker and the broncoscope will be advanced as a single unit into the target part of a right or left lung. The broncoscope will be withdrawn into the trachea and the blocker cuff will be inflated and the position of the blocker will be confirmed using the fiberoptic broncoscope. The wire loop will be removed after correct placement of the blocker. Once the guide wire is removed, the blocker can't be replaced.
