Patients with single ventricle physiology (hypoplastic left heart syndrome, tricuspid atresia) frequently have feeding difficulties necessitating procedures such as Nissen fundoplication and G-tube placement. With advances in minimally invasive surgery, these are frequently performed using laparoscopic techniques. Although generally safe and effective, the increase in IAP during laparoscopy may increase systemic and pulmonary vascular resistance and decrease cardiac output. This prospective study will include 50 patients with single ventricle physiology presenting for laparoscopic procedures. There will be no change in the anesthetic or perioperative care of these patients. Tissue and cerebral oxygenation will be monitored using near infrared spectroscopy (NIRS).
Study Type
OBSERVATIONAL
Cerebral oxygenation monitor which is standard of care for this surgery.
Nationwide Children's Hospital
Columbus, Ohio, United States
Change in cerebral oxygenation values
Measured on the NIRS cerebral oxygenation monitor attached to the patient.
Time frame: From baseline to insufflation (average time frame of 30 mins. - 2 hrs.)
