Airway Responsiveness, Intubation; Difficult or Failed
Conditions
Brief summary
Endotracheal intubation plays an important role in general anesthesia. Complications can be prevented by using alternative airway devices in predetermined difficult intubation cases. In this study, the investigators aimed to compare the results of endotracheal intubation with video fiberscope and DCI video laryngoscope devices of two different experienced physicians (E and H).
Detailed description
In this randomized and prospective study, 60 patients with EGRI score\> 4 and ASA score \<4, operated between 1 October 2018 and 1 March 2019 in Ondokuz Mayıs University Medical Faculty Hospital were included. Endotracheal intubation was performed by two practitioners using two different devices. Intubation times, number of attempts, failed attempts, postoperative complications and hemodynamic responses were recorded.
Interventions
DEVICEGroup video fiberscope of experienced practitioner
One of the classical alternatives to laryngoscopy in difficult endotracheal intubation is video laryngoscopyvideo fiberscope( Karl Storz GmbH &Co. KG, Tuttlingen, Germany). Reaching the image from the patient with pre- and from the cervical point of view, or from the cervical point of view, to be completed with a good view from a large screen to be completed with an image before and within intubation. It also facilitates learning in education.

Intubation Pending Difficult as well as challenging . Fiberoptic (fiberscope) intubation is the gold standard in difficult airway. Lacking this supplement, it will be widely used for practice, as it is suitable for video laryngeal.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intubation times, | during intubation | The moment when the endotracheal intubation tube was passed between the vocal cords following the vocal cord image obtained with the device was recorded in seconds. In endotracheal intubation performed with a video fiberscope, the end of the fiberscope with a camera passing through the vocal cords, and in endotracheal intubation performed with a DCI video laryngoscope, the intubation tube passing between the vocal cords was counted as successful intubation time. |
| Number of attempts | during intubation for patients, | The procedure will be considered unsuccessful if intubation is unsuccessful in three attempts, if the intubation process exceeds three minutes, or if the peripheral oxygen saturation (SpO2) is \<90% during this period. If this situation was encountered, it was planned to ventilate the patient with an anesthesia mask until the oxygen saturation approached 100% and to use alternative airway devices. |
| Time to find the glottis: | during intubation for patients | The time from the moment the device entered between the patient's anterior incisors until the vocal cords were seen was recorded in seconds. |
| Blood pressure | During intubation, at 1st, 2nd and 5th minutes after intubation | Hemodynamic parameters; heart rate (/min), systolic blood pressure (mmHg), diastolic blood pressure (mmHg), mean arterial pressure (mmHg), and SpO2 were recorded before induction (baseline), during intubation, at 1st, 2nd and 5th minutes after intubation |
| Pulse oximeter | Before induction (baseline), during intubation, at 1st, 2nd and 5th minutes after intubation | Oximetry is a convenient and painless alternative to needlesticks, is simple to use, and provides immediate data. These advantages make oximetry an invaluable tool for determination the client's need for oxygen therapy and assessing effectiveness of therapy. The oximeter registers arterial oxygen saturation (SaO2). An SaO2 greater than 95% is considered normal, whereas values lower than 93% usually indicate the need for oxygen therapy and further assessment. |
