Esophagus is intentionally intubated with a cuffed endotracheal tube, the cuff inflated to >30cm water pressure, a force transducer attached, and force of extubation recorded. Then Trachea is intentionally intubated the cuff inflated to >30cm water pressure, and force of extubation recorded.

Esophagus is intentionally intubated with a cuffed endotracheal tube, the cuff inflated to >30cm water pressure, a force transducer attached, and force of extubation recorded. Then Trachea is intentionally intubated the cuff inflated to >30cm water pressure, and force of extubation recorded.
Measuring extubation force: Intubation of the esophagus of anesthetized participants who are having planned endotracheal intubate for surgery; inflation of the cuff; attachment of a force transducer to the tube connector; and gently tugging the tube out of the mouth. Then intubating the esophagus and repeating the tugging procedure. Meanwhile, the force of resistance to tugging is measured with a force transducer.

Force of Endotracheal Tube Extubation; Esophagus vs. Trachea; an Exploratory Crossover Clinical Trial

Our intubation studies have generated a large database of tracheal length measurements that, with this study added, should probably be published separately.

Transnasal endoscopy without sedation with ultra-thin endoscopes in patients who are candidates for bariatric surgery

transnasal endoscopy

Will be carried out topical anesthesia of the pharynx with lidocaine spray (10%) 6 puffs and instillation of nasal vasoconstrictor 4 drops.

Transnasal Endoscopy in Obese Patients Are Candidates for Bariatric Surgery

Transnasal Endoscopy in Obese Patients Are Candidates for Bariatric Surgery: Feasibility, Tolerance, Security and Cost-effectiveness.

The exam will be considered feasible if the appliance reaches the second duodenal portion and is performed retroflexão, allowing the visualization of all portions of the digestive system and the achievement of biopsies if necessary.
All patients will complete a questionnaire 15 to 30 minutes after the transnasal endoscopy and will be released next to the house.
All of this information and the results will be compared with the main data in the literature. Bivariate analyzes shall be calculated from the test "t" test for continuous variables and the chi-square test or Fisher exact test for categorical variables. Proportions will be reported by categorical data; and mean, median and standard deviation for continuous variables. P values less than 0.05 are considered statistically significant.

Participants can be identified by the number of medical records and phone contacts have been duly authorized by the institution responsible.
