NCT ID: NCT04959149 Completed - Obesity, Morbid Clinical Trials

Face-to-face Intubation in Morbidly Obese

Start date: March 1, 2020
Phase: N/A
Study type: Interventional

Introduction : In a typical endotracheal intubation, the patient is in the supine position, with the anesthetist standing behind his head and with adequate access to the head and neck of the patient. However, there are several situations, where traditional intubation is very difficult or even impossible. In immobilised trauma victims, with limited access to the head, suspected cervical spine injury or in sitting positioned patient an intubation performed by a person standing in front of a patient might be the only chance of airway management. Moreover, in case of general anesthesia in bariatric patients, face-to-face (inverse) method is increasingly being considered due to upper body elevation position, recommended in this group of patients. This was a parallel randomised controlled trial in patients scheduled for planned sleeve gastrectomy in Barlicki University Hospital, Lodz, Poland. Randomization and allocation to trial group were carried out by drawing envelopes by independent observer before a procedure. Randomized and recruited participants were 76 adults (typical intubation n= 36, face-to-face intubation n=40). Main outcome was a time of intubation using Airtraq video laryngoscope measured by independent assistant.

NCT ID: NCT04844723 Completed - Anesthesia Clinical Trials

Pediatric Videolaryngoscopic Intubation and Difficult Airway Classification

PeDiAC
Start date: April 12, 2021
Phase:
Study type: Observational

The study's primary aim is to develop and validate a multivariable diagnostic model for the prediction of difficult videolaryngoscopy (the 'PeDiAC classification') in children undergoing general anesthesia with tracheal intubation. The secondary aim is to compare the diagnostic performance of the PeDiAC-classification with the Cormack-Lehane classification.

NCT ID: NCT04779528 Completed - Anesthesia Clinical Trials

Awake Nasal Fiber-optic Intubation of Severely Obese Patients in Lateral Position

Start date: March 1, 2021
Phase: N/A
Study type: Interventional

Airway management in severely obese patients remains a challenging issue for anesthetists and may lead to life-threatening situations. Awake Fiber-Optic Bronchoscopy Intubation (FOBI) technique is considered as the gold standard when a difficult airway is anticipated to secure the airway and to facilitate the surgery. FOBI is usually done in supine position, while (in conscious patients) lateral position is the most recommended position to keep the upper airway patent. This prospective clinical trial study will test whether awake FOBI in Lateral position will provide a safe profile or a significant advantage over FOBI in supine position, in morbidly obese patients undergoing elective bariatric surgery.

Effect of Back up Head Elevated Position on Laryngeal Visualization.

Start date: January 18, 2021
Phase: N/A
Study type: Interventional

In patients with limited neck extension and mouth opening due to reasons including previous radiation therapy in the head and neck area or cervical spine pathology, tracheal intubation with direct laryngoscopy (DL) are challenging because of the difficulty in aligning the oral, pharyngeal, and laryngeal axes in order to visualize the cords. In contrast, video-laryngoscopes (VL) only require alignment of the pharyngeal and laryngeal axes, which lie along much more similar angles when compared with the oral axis. Thus, VL make tracheal intubation easier to accomplish in these patients. Good patient positioning also maximizes the chance of successful laryngoscopy and tracheal intubation. In difficult airway society 2015 guidelines, advantages of head-up positioning and ramping, which brings the patient's sternum onto the horizontal plane of the external auditory meatus (EAM), are highlighted. In the obese patient, the 'ramped' position should be used routinely because this improves the view during DL. This position is usually achieved by placing blankets or other devices under the patient's head and shoulders, but can also be achieved simply by configuring the operation room (OR) table into a back-up head elevated (BUHE) position. Significantly improved glottic views on DL have been reported with both obese and non-obese adult patients in BUHE position. However, the effect of this simple maneuver on laryngeal visualization with the VL in patients with limited neck extension and mouth opening has not been reported. The investigators hypothesized that BUHE position might improve laryngeal views and make intubation easier compared to the supine position with the VL in patients with simulated difficult airway (application of a cervical collar to limit mouth opening and neck movement).The investigator investigated primarily the improvement in visualization of the glottis and, secondarily, the ease of tracheal intubation after alignment of the EAM and sternal notch.

Optimal Intubating Technique Using Videolaryngoscopy in Patients With Semi-rigid Neck Collar

Start date: October 7, 2020
Phase: N/A
Study type: Interventional

In the case of tracheal intubation using a video laryngoscope, both techniques, one is 'conventional technique' in which intubation is performed by placing the blade tip on the vallecula and the other is 'sliding technique' performed by sliding the blade under the epiglottis, are commonly conducted by anesthesiologists. Investigators would like to compare if the sliding technique can improve the condition of tracheal intubation in patients wearing semi-rigid neck collars in cervical spine surgery.

NCT ID: NCT04542187 Completed - Obesity, Morbid Clinical Trials

Pre-Operative Airway Assessment of Patients With Morbid Obesity

Start date: January 1, 2019
Phase:
Study type: Observational

Backround:The incidence of difficulty in laryngoscopy and endotracheal intubation is more common in obese patients. There are conflicting data on factors predicting difficult intubation. Also, these predictors are uncertain when video laryngoscopy (VL) is used. In this study we aim to investigate the correlation between airway assessment tests, anthropometric measurements and Modified Cormack-Lehane Classification (MCLC), assessed by C-MAC-D-blade VL and predictive values for intubation difficulty in class-III patients. Methods: This prospective observational study was performed in 121 obese patients (Body mass index (BMI)≥45kg/m2) undergoing bariatric surgery. BMI, modified mallampati scores (MMS), thyromental distance (TMD), sternomental distance (SMD), interincisor distance (IID), and neck, waist, and chest circumference were all recorded preoperatively. Endotracheal intubations were performed with a C-MAC D-blade VL. The glottic view and intubation difficulty were determined according to the MCLC. MCLC I-IIa was recorded as the group with no risk of a difficult intubation, the MCLC IIb-III was recorded as the group with risk of a difficult intubation and the MCLC-IV was recorded as the group with a difficult intubation. The correlation between the airway tests, anthropometric parameters and the MCLC, as well as their sensitivity and specificity in predicting the intubation difficulty based on the MCLC, were analyzed. The duration of intubation, number of attempts, external laryngeal maneuver, the equipment requirements (style, guide), and complications during intubation were recorded.

McGRATH vs Macintosh Laryngoscopy Comparison in LMA Insertion

GRAN-PALM
Start date: August 30, 2020
Phase: N/A
Study type: Interventional

Various techniques have been developed to get a good LMA position, one of them is using a laryngoscope. The most popular laryngoscope used for LMA installation is the Macintosh type. Technological developments have brought laryngoscopes into the video era, one of which is McGRATH's laryngoscope, which from several studies about having an advantage in terms of the first attempt, time, complications, and hemodynamic stability of intubation. It needs to be proven through research on the comparison of clinical outcomes of LMA installation with McGrath laryngoscope and Macintosh laryngoscope.
