Trial summary

Extubation and emergence from anesthesia lead to systemic and cerebral hemodynamic changes that can cause cerebral edema and hemorrhage. The hemodynamic profile on emergence is more favorable if a laryngeal mask airway (LMA) is inserted before neurosurgical patients emerge from anesthesia. Read more about this study

About this study

Official title: Proseal Laryngeal Mask Airway Attenuates Systemic and Cerebral Hemodynamic Response During Awakening of Neurosurgical Patients

Extubation and emergence from anesthesia lead to systemic and cerebral hemodynamic changes that can cause cerebral edema and hemorrhage. The hemodynamic profile on emergence is more favorable if a laryngeal mask airway (LMA) is inserted before neurosurgical patients emerge from anesthesia. We aimed to compare the impact of awakening neurosurgery patients after insertion of a ProSeal LMA to replace the endotracheal tube (ETT).

Read the detailed description

At the end of surgery, the anesthesiologist opened a sealed envelope labeled with software-generated randomized numbers to learn the patient's assignment to one of two groups to emerge from anesthesia with the ETT still in place or after it had been replaced by an LMA.

Hemodynamic variables were recorded at 8 moments: baseline, in the operating room one minute before anesthetic induction; 5 minutes after the end of surgery before awakening (ETT group) or before tube replacement (LMA group); and 1, 5, 10, 15, 30 and 60 min after extubation or LMA removal (according to group assignment).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Endotracheal tubeProcedure or surgery

    Hemodynamic variables were recorded at 8 moments: baseline, in the operating room one minute before anesthetic induction; 5 minutes after the end of surgery before awakening (ETT group) and 1, 5, 10, 15, 30 and 60 min after extubation . The last blood pressure and heart rate measurements were taken in the postoperative recovery room.

  • LMAProcedure or surgery

    Also called Laryngeal mask

    Hemodynamic variables were recorded at 8 moments: baseline, in the operating room one minute before anesthetic induction; 5 minutes after the end of surgery before tube replacement (LMA group); and 1, 5, 10, 15, 30 and 60 min after LMA removal. The last blood pressure and heart rate measurements were taken in the postoperative recovery room.

What is being measured

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

  1. systolic blood pressure change

    Measured: 1 minute before anesthesia induction, 5 minutes before extubation, and minute 1, 5, 10, 15, 30 and 60 after extubation

Secondary outcomes (1)
  1. heart rate change

    Measured: 1 minute before anesthesia induction, 5 minutes before extubation, and minutes 1,5,10,15,30 and 60 after extubation

Questions about this trial

What is this clinical trial studying?

A study testing Endotracheal tube and LMA in people with Hypertension on Emergence, run by Ricard Valero at 1 site in Spain.

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 3 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 31 Oct 2012. 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 Spain. 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?

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?

systolic blood pressure change (time frame: 1 minute before anesthesia induction, 5 minutes before extubation, and minute 1, 5, 10, 15, 30 and 60 after extubation). 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 NCT01718470, 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 31 Oct 2012.
