What is being measured
The primary outcome is the main question the study is designed to answer.
Nephrogenic Diabetes Insipidus prevalence
How many patients under sevoflurane sedation ultimately develop NDI? NDI confirmed by demonstrating the absence of a urine concentrating response to exogenous Arginine Vasopressine.
Measured: up to 8 weeks
Secondary outcomes (10)
Number of patients that develop risk factors of NDI
Number of patients that develop risk factors (electrolyte disorder, urinary obstruction) for NDI.
Measured: up to 8 weeks
Amount of time patient was placed under sevoflurane sedation.
How long are they under sevoflurane sedation.
Measured: up to 8 weeks
Number of patients with electrolyte abnormalities as assessed by lab results.
Lab results of hematology and chemistry labs show an electrolyte imbalance.
Measured: during hospitalization, up to 8 weeks.
Number of patients with excessive urine output
Amount of urine output: >40 ml/kg/24h
Measured: during hospitalization, up to 8 weeks.
Number of patients with an abnormal physical examination.
Typical physical symptoms of (N)DI: tired, lethargic, tachycardia, tachypnea, hypotension and dry mucous membranes.
Measured: during hospitalization, up to 8 weeks.
Number of patients with urine with an abnormal osmolality
Lab testing of urine: osmolality < 300 mosm/kg
Measured: during hospitalization, up to 8 weeks.
Number of patients that show an abnormal amount of fluid intake
>2.5l/day
Measured: during hospitalization, up to 8 weeks.
Number of patients that have an abnormal abdominal echo of the bladder.
Echo shows an enlarged bladder.
Measured: during hospitalization, up to 8 weeks.
Number of symptoms of NDI
Number of symptoms of NDI do these patients show?
Measured: up to 8 weeks
Timing of symptoms of NDI
After how much time do these patients show symptoms of NDI?
Measured: up to 8 weeks

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Nephrogenic Diabetes Insipidus prevalence (time frame: up to 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2023; AzTrials last refreshed its copy on 8 Nov 2026.
