ClinConnect Summary

This study is testing whether using ultrasound to guide a lung-reopening technique at the end of surgery can help reduce lung collapse (atelectasis) and related breathing problems in children. Involving kids aged 1 to 14 who are having surgery that is expected to take at least 2 hours, participants are randomly put into three groups: Group 1 receives a standard small amount of breathing support (PEEP) during the operation; Group 2 gets the same support plus a short “recruitment maneuver” at the end of surgery to reopen any collapsed airways; Group 3 gets the same standard support plus a similar maneuver performed while the child lies on their side. The lungs will be checked with ultrasound before anesthesia, shortly after induction, before the end-of-surgery maneuver, and shortly after extubation to measure lung appearance and any blocks in air flow. Researchers will monitor heart rate, blood pressure, oxygen levels, and other breathing-related measures during surgery and for 24 hours afterward.

Eligible children include those 1–14 years old with an ASA health status of 1–3 and a planned surgery lasting at least 2 hours. Exclusions include more serious heart or lung conditions, a history of prematurity with lung problems, cystic fibrosis, certain chest or spine issues, previous chest surgery, or procedures done with a laparoscope. The study is randomized and double-blind (the child and some researchers don’t know which group the participant is in). Results are not yet available. It is being conducted at Istanbul University-Caerrahpasa in Turkey, with about 78 participants planned and results expected in early 2025.
