About this study
Official title: The Effects of Endotracheal Intubation Via McGrath Videolaryngoscope on Intraocular Pressure
In this study, the investigators aimed to compare the effects of endotracheal intubation via direct laryngoscope (DLS) and McGrath Videolaryngoscope (VL) on intraocular pressure.
Read the detailed description
Total of 50 American Society of Anesthesiologist Grade 1-2, Mallampati score 1 or 2, age between 18 to 65 patient planned to undergo nonopthalmic surgery will be included to study. Patients with glaucoma, diabetes mellitus, cardiovascular and pulmonary diseases, American Society of Anesthesiologist Grade III and IV, Body mass index more than 35, difficult intubation, undergo obstetrical surgery and propofol, fentanyl, rocuronium contraindicated will be excluded from the study. Patients will be divided randomly into 2 groups as direct laryngoscopic and videolaryngoscopic intubation group. Patients will be preoxygenated with %100 O2 for 3 minutes then anesthesia will be induced using propofol 2 mg / kg, fentanyl 1 mcg/kg, and rocuronium 0,5 mg / kg in both groups. After 3 minutes mask ventilation, patients will be intubated (women with No:7-7,5, men with No:8-8,5 intubation tube) by oral route. systolic blood pressure, diastolic blood pressure, mean arterial pressure, peripheral oxygen saturation, perfusion indexwill be recorded and intraocular pressure measured by ophthalmologist by tonopen device will be recorded pre-induction (basal), after induction, 1,2,3,5 minutes after intubation, respectively. Period between handling of laryngoscope or videolaryngoscope after termination of mask ventilation and obtain end tidal carbon dioxide will be accepted as application time and recorded. Study will be terminated after 5th minute values taken.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
VideolaryngoscopeOther
This device is used in endotracheal intubation and tonopen device for measuring of intraocular pressure. The investigators want to evaluate which one is better.

| Videolaryngoscopy | Active comparator | Evaluate the difference between the two groups about hemodynamic and intraocular pressure responses. Receives: Other: Videolaryngoscope |
| Direct laryngoscopy | Active comparator | Evaluate the difference between the two groups about hemodynamic and intraocular pressure responses. Receives: Other: Direct laryngoscope |

Questions about this trial
What is this clinical trial studying?
A study testing Videolaryngoscope and Direct laryngoscope in people with Intraocular Pressure, run by Inonu 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 4 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 5 Apr 2017. 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?
Systolic blood pressure (time frame: From Beginning of Anesthesia induction to 5th minutes of intubation). The study lists 4 primary outcomes in all. 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 5 Apr 2017.
