G-O015 - COMPLICATIONS AND RISK FACTORS IN PAEDIATRIC ANAESTHESIA FOR PLACEMENT OF A PERCUTANEOUS ENDOSCOPIC GASTROSTOMY (PEG) IN CHILDREN (ID 1411)
Objectives and Study
PEG feeding has become standard of care for a select group of chronically ill and often small children. Peri- and post-interventional complications of tube insertion are well described. Only limited data exist about the anaesthetic risks in adults but none in this specific paediatric cohort.
The aim of this study is the evaluation of complications and risk factors in paediatric anaesthesia for the PEG placement in our own center.
Patient case notes of all children receiving PEG insertion at our institution were analyzed. Included were all consecutive cases from February 2020 to April 2022. No exclusion criteria applied. All patients underwent the procedure as in-patient cases. Ethical approval for this retrospective analysis was granted by the ethical committee of the Hannover Medical School (10615_BO_K_2022).
Thirty-one patients, aged 2 months to 17 years, have been identified. The underlying diagnosis for PEG placement was predominantly feeding difficulties due to various pediatric conditions. Weight ranged from 2.0 to 47.0 kg. Thirty-seven-point five percent of these patients were under the age of 1 year and 75.0% had an American Society of Anesthesiologist’s physical status classification (ASA) of III or higher. In 51.6% cases, pulmonary complications were detected.
Laryngospasm and bronchospasm occurred in 3.2% each with desaturation below 90 %. Ventilation problems with increased ventilation pressure > 10 points above the initial value and hypercapnia > 60 mmHg occurred in 35,5%. Fifty percent of the children with compromised oxygenation or ventilation were younger than one year of age.
Twelve-point nine percent of all patients needed mechanical ventilation post intervention and 19.4% had a newly occurred demand for oxygen supply.
Although considered a routine procedure with a good safety record, the PEG insertion can cause significant anaesthetic complications in children. Especially younger children and patients with a higher ASA are more likely to suffer severe pulmonary complications.
