Monitoring During Deliberate Hypotensive AnesthesiaPPINCT03007355
Peripheral Perfusion Index (PPI) as Monitor During Deliberate Hypotensive Anesthesia
An observational study of Monitoring During Deliberate Hypotensive Anesthesia, run by Cairo University.
Trial summary
Hypotensive anesthesia is effective in reducing the intraoperative blood loss. The risk of hypoperfusion of vital organs continues to be a concern. An adequate monitoring of tissue perfusion and oxygenation is crucial issue. Read more about this study

About this study
Official title: The Use of Peripheral Perfusion Index as a Predictor for Patient's Response to Deliberate Hypotension During Functional Endoscopic Sinus Surgery A Prospective Observational Study
Hypotensive anesthesia is effective in reducing the intraoperative blood loss. The risk of hypoperfusion of vital organs continues to be a concern. An adequate monitoring of tissue perfusion and oxygenation is crucial issue. Peripheral Perfusion Index (PPI) as a noninvasive new monitoring, can reflect the peripheral perfusion dynamics.
This study is designed to explore the behaviour and trend of PPI during nitroglycerine induced deliberate hypotensive anesthesia in adult patients undergoing functional endoscopic sinus surgery (FESS).

correlation between PPI and T1
correlation of baseline values of PPI and time required to achieve target mean arterial pressure.
Measured: start of nitroglyceirn infusion till target arterial pressure is reached up to 2 hours

Questions about this trial
What is this clinical trial studying?
An observational study of Monitoring During Deliberate Hypotensive Anesthesia, run by Cairo University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
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?
correlation between PPI and T1 (time frame: start of nitroglyceirn infusion till target arterial pressure is reached up to 2 hours). 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 19 Dec 2018; AzTrials last refreshed its copy on 7 Nov 2026.
