2.2 Participants
Patients with CTS who underwent slide tracheoplasty at our hospital
between January 2015 and August 2019 were included in the study. Same
surgeons worked throughout the study. Clinical data were collected
before and after the establishment of the closed-PICU management system
following the relocation of the hospital in May 2016 were
retrospectively reviewed. Patients were categorized into two groups: an
open-PICU group and a closed-PICU group. The open-PICU group underwent
surgery between January 2015 and April 2016 and perioperative management
was provided in an open PICU by cardiovascular and pediatric surgeons.
The closed-PICU group underwent surgery between May 2016 and July 2019
and perioperative management was provided in a closed PICU by pediatric
intensivists.
