About this study

Intraocular pressure is significantly increase during robot-assisted laparoscopic radical prostatectomy which is performed in a steep trendelenburg position at prolonged times of pneumoperitoneum. Therefore investigators decided to evaluate the impacts of surgical visibility through deep neuromuscular blockade on intraocular pressure in patients undergoing Robot-Assisted Laparoscopic Radical Prostatectomy.

Being tested
deep neuromuscular blockade, moderate neuromuscular blockade, Rocuronium, Sugammadex, Atracurium
Keywords
deep neuromuscular blockade, intraocular pressure

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum Intraocular Pressure During RALRP Under Deep Neuromuscular Blockade

    maximum intraocular pressure during RALRP under deep neuromuscular blockade after being positioned in the steep Trendelenburg position with CO2 pneumoperitoneum under deep neuromuscular blockade

    Measured: Maximum intraocular pressure was measured at 60 minutes after CO2 pneumoperitoneum in the ST position

Secondary outcomes (1)
  1. Overall Surgical Condition

    overall surgical conditions using the 5-point rating scale as previously described: Grade 5 (optimal), optimal surgical conditions; grade 4 (good), nonoptimal conditions, but an intervention is not required; grade 3 (acceptable), wide surgical view, but an intervention can improve surgical conditions, grade 2 (poor), inadequate conditions, there is a visible view, but an intervention is necessary to ensure acceptable surgical conditions; grade 1 (extremely poor), inability to perform surgery; therefore, intervention is necessary.

    Measured: At the end of the Steep trendelenburg position, an average of 1 hour

Questions about this trial

What is this clinical trial studying?

A study testing deep neuromuscular blockade, moderate neuromuscular blockade and Rocuronium in people with Robot-Assisted Laparoscopic Radical Prostatectomy, run by Yonsei University at 1 site in South Korea.

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 3 inclusion and 16 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 24 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 24 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximum Intraocular Pressure During RALRP Under Deep Neuromuscular Blockade (time frame: Maximum intraocular pressure was measured at 60 minutes after CO2 pneumoperitoneum in the ST position). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02109133, which also lists 1 linked publication.

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 24 Jun 2015.
