简要总结
Antecedentes In patients with expected difficult airways undergoing surgery, tracheal intubation must be performed with a fiberoptic bronchoscope or video laryngoscope while keeping the patient awake and under the effects of anesthetic sedation.
Objective: To determine and compare the existence of postoperative memories of the patients and the different levels of sedation (Ramsay scale) obtained during the intubation procedure.
Methods Prospective observational study that includes 100 patients older than 18 years who are going to undergo surgery, who need fiberoptic bronchoscopy/videolaryngoscopy for tracheal intubation due to the planned difficult airway and intravenous sedation. Patients with an unexpected difficult airway, under 18 years of age and/or with cognitive impairment will be excluded. After checking the tracheal intubation, the general anesthesia indicated for each patient will be used.
Twenty-four hours after tracheal extubation, the patient will be questioned about the pain presented during the fiberoptic bronchoscopic/videolaryngoscopic procedure and postoperative memories based on a modified Brice questionnaire. At 30 days after surgery, the postoperative memories of the patients will be evaluated again by telephone interview.
详细描述
Background In patients with expected difficult airways undergoing surgery, tracheal intubation must be performed with a fiberoptic bronchoscope or video laryngoscope while keeping the patient awake and under the effects of anesthetic sedation. The intravenous sedation has the advantages of relieving anxiety, providing maximum comfort to the patient, facilitating examination, and producing amnesia of the episode. As an inconvenience, it can produce a depression of the respiratory system, fearsome in patients with expected difficult airway. Given the fear of the appearance of respiratory depression in these patients, the levels of sedation achieved are usually not very deep, and there may be pain and the presence of unpleasant postoperative memories in relation to the intubation technique using bronchoscopy/videolaryngoscopy.
Main objective: To determine and compare the existence of postoperative memories of patients who need conscious tracheal intubation, but under the effects of sedation, due to the planned difficult airway, depending on whether intubation was performed with a fiberoptic bronchoscope or video laryngoscope.
Secondary objective: To determine if there is a relationship between the appearance of postoperative memories and the different levels of sedation (Ramsay scale) obtained during the intubation procedure.
Other objectives: To determine if the duration of tracheal intubation time influences the incidence of postoperative memories. Determine the incidence of respiratory depression (SpO2 <90%) during the tracheal intubation procedure. Pain presented by patients during the procedure.
