Internal Jugular Vein Distensibility in Assessment of Fluid Responsiveness in Donors of Living Donor Liver Transplantation

Completed

• Conditions: Monitoring During Anesthesia
• Interventions: Diagnostic Test: Internal Jugular Vein Distensibility

• Registration Number: NCT03391037
• Lead Sponsor: Ain Shams University

Brief Summary

Egypt has a very high prevalence of HCV and a high morbidity and mortality from chronic liver disease, cirrhosis, and hepatocellular carcinoma. Approximately 20% of Egyptian blood donors are anti-HCV positive. Egypt has higher rates of HCV than neighboring countries as well as other countries in the world with comparable socioeconomic conditions and hygienic standards for invasive medical, dental, or paramedical procedures.

Donor safety is on the top of our priorities as a team and it is widely recognized intraopertively during hepatectomy, there are several potential risks during the Perioperative period .

Detailed Description

to a conclusion that intraoperative fluid management aids to the reduction of the intraoperative bleeding during the procedure, adequate and guided fluid management is considered one of the important strategies to reduce the blood loss besides of the other anesthetic techniques like hemodilution, normovolemia, cell salvage usage , high Stroke volume variation (SVV) method ,and low CVP technique , the last method is considered the most applicable, simpler, and cost effective technique which could be easier to be performed.

Arm && Interventions

Group	Intervention	Description
Intervention	Internal Jugular Vein Distensibility	diagnostic criteria for volume assessment were heart rate (HR), mean arterial blood pressure (MABP), central venous pressure (CVP), and urine output hourly (UOP) in ml/hr. During period of hypovolemia, all enrolled patients had left IJV scanned (T0) and measured by one anesthesiologist experienced in point-of-care ultrasound. This point-of-care anesthesiologist is not involved in the anesthetic management of the patient and blinded to the volume status of the patient values. Hypovolemic patients were given a fluid bolus in the form of ringer acetate 5 ml / Kg. Ultrasonic and hemodynamic measurements are reassessed 10 minutes (T 10) after the fluid resuscitation.

Primary Outcome Measures

Name	Time	Method
correlation between CVP and IJV distensibility	10 min	IJV distensibility is the difference between maximum diameter of IJV and minimum diamter in Manchester mode divided by minimum diameter
