The purpose of this study is to determine whether Kidney injury happens in controlled hypotension during brain operations by using Neutrophil Gelatinase Associated Lipocalin ELISA Kit and if so, does VitaminE+Selenium prevent it

Condition Intervention Phase
Acute Kidney Injury Drug: vitamin E +Selenium Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Assessment of Preventive Effect of Vitamin E +Selenium on Acute Kidney Injury Through NGAL in Patients Undergoing Controlled Hypotension During Neurosurgery Operations

Further study details as provided by Zahed Hosein Khan, Tehran University of Medical Sciences:

Primary Outcome Measures:
  • increased amount of urinary or serum NGAL after controlled hypotension [ Time Frame: from 2 hours to 24 hours after controlled hypotension ]

Estimated Enrollment: 60
Study Start Date: June 2011
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: vitamin E +Selenium
    vitamin E 400 IU once 8 hrs before operation selenium 150 mic once 8 hrs before operation
Detailed Description:
NGAL(Neutrophil Gelatinase Associated Lipocalin) is a 25KD protein which bounds with Gelatinase in Neutrophil granules.It is also expressed in epithelial cells of kidney tubules.NGAL increases in ischemic and toxic injuries of kidney. During controlled hypotension in brain operations injury to the kidneys might occur . This study is designed to assess this possibility and evaluate the effect of VitaminE+Selenium on prevention of this problem

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
