Post Graduate Institute of Medical Education and Research, Chandigarh

Status: Completed

Conditions: Anesthesia, General; Mechanical Ventilation; Anesthesia, Endotracheal; Fluid Responsiveness

Treatments: Other: Measurement of aortic and carotid Doppler peak systolic velocity variation

Study type: Observational

Funder types: Other

Identifiers

NK/3046/MD/400

Details and patient eligibility

About

The purpose of this study is to evaluate whether carotid Doppler peak systolic velocity can be an easy to measure possible surrogate for echocardiographic measurement of aortic peak systolic velocity variation which is an index of fluid responsiveness in mechanically ventilated children intra-operatively.

Enrollment: 52 patients

Sex: All

Ages: 1 to 12 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients scheduled for mon-cardiac surgeries under general endotracheal anaesthesia in supine position with expected duration more than 1 hour

Exclusion criteria

• Known congenital heart disease
• Any non-sinus rhythm, arrhythmias
• Patients on vasoactive medications
• Chest wall deformities, situs non solitus (eg. dextrocardia)
• Patients scheduled for open chest surgeries
• History of neck surgery/ carotid interventions

Trial design
