A 23-year-old healthy man was scheduled for extraction of his mandibular third molars under general anesthesia with nasotracheal intubation. Sudden sinus tachycardia up to 170 beats/min occurred when applying an epinephrine solution-soaked swab into the nasal cavity for preventing epistaxis during intubation. This was presumably evoked by submucosal migration of the swab into a false passage created because of the force applied during a prior failed attempt at nasal passage of the tracheal tube, and rapid epinephrine absorption by the traumatized mucosa. The causes of the unexpected severe tachycardia in our patient are discussed.

Salivary Bypass Tube is an important tool to prevent or treat some complications of laryngeal and hypopharyngeal surgery and its placement may prove difficult. In this article, we propose a new technique to simplify its management by using an Oral/Nasal Tracheal Tube Cuffed-Reinforced that allowed us to reduce operating times, complications related to prolonged general anesthesia, and the traumas on the tissues incurred during the forced positioning of the device with standard techniques.

Abstract Background: High cuff pressure can induce ischemic injury to the trachea. An esophageal stethoscope can increase the cuff pressure. The purpose of this study was to evaluate the effect of an esophageal stethoscope insertion on the cuff pressure.Methods: Patients, who were scheduled for surgeries under general anesthesia, were enrolled in this prospective observational study. After induction of anesthesia, an anesthesiologist intubated a tracheal tube into the patient’s trachea and inflated the cuff manually. Then, an investigator checked the initial cuff pressure using a manometer. Next, the cuff pressure was adjusted to 24-26 mmHg. The cuff pressure was rechecked after insertion of an esophageal stethoscope. We recorded the change in cuff pressure by esophageal stethoscope.Results: One hundred twelve patients completed this study. The cuff pressure increased by an esophageal stethoscope in almost all patients and the mean cuff pressure change was 3.0 ± 3.4 cmH2O in all patients. Among all subjects, cuff pressure change over 5 cmH2O was recorded in 24 patients. When we compared the patient characteristics between patients whose cuff pressure changed over 5 cmH2O with that of other patients, females were more affected by insertion of an esophageal stethoscope, in terms of cuff pressure increase.Conclusion: Esophageal stethoscope insertion could increase cuff pressure, and females are more affected by it. Therefore, anesthesiologists should check the cuff pressure with a manometer after insertion of an esophageal stethoscope and readjust the pressure appropriately.Trial registration: ClinicalTrials.gov Identifier NCT03375554, registered on 12 December 2017 (https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0007N0H&selectaction=Edit&uid=U00026JX&ts=2&cx=-ivu5vz)

AbstractAwake craniotomy (AC) is indicated to excise a lesion close to an eloquent area of the brain. Success of this procedure depends upon the patient’s active participation during the awake phase of the surgery, especially for brain mapping. Occasionally, a patient may refuse to remain awake during the surgical procedure and demand general anesthesia (GA). A 27-year-old male with uncontrolled seizures from recurrent brain tumor near motor area refused to consent for AC citing his past unpleasant experience; so, the decision to administer GA was taken. To avoid straining/coughing on tracheal tube, his airway was anesthetized with transtracheal xylocaine, bilateral superior laryngeal nerve block, and inflation of tracheal tube cuff with xylocaine. GA was maintained with sevoflurane, infusion of fentanyl, and rocuronium. To awaken him, anesthetics were discontinued and rocuronium antagonized with sugammadex. Intravenous lignocaine and midazolam were administered to supress cough reflex and produce amnesia, respectively. He tolerated the entire duration of 30 minutes of brain mapping with electrocorticography and neurological testing comfortably. Upon completion of brain mapping, GA was reintroduced and the lesion excised. The surgical outcome was good with no neurological deficit. When interviewed postoperatively, the patient had no recall of the awake phase.

Anesthesia Breathing

A Silky terrier weighing 4.7 kg was presented with an airway foreign body after having aspirated a fragment of an orotracheal tube that was identified on radiological examination. Due to the small size of the patient, flexible endoscopy could not be performed through the lumen of a tracheal tube. Following IV induction of general anesthesia, the airway was instrumented with a laryngeal mask airway that was attached via a three-way connector to an anesthesia breathing circuit. A flexible endoscope was passed through the free port of the connector. That arrangement allowed for the passage of an endoscope through the lumen of the laryngeal mask airway and into the trachea without interrupting the continuous supply of O2 and sevoflurane.

Alternative Method

Possible complications of nasotracheal intubation include injury to the nasal or pharyngeal mucosa. Dissection of the retropharyngeal tissue by the endotracheal tube is one of the rarer of the more severe complications. Previous studies have indicated that the Parker Flex-Tip (PFT) tracheal tube (Parker Medical, Highlands Ranch, Colo) reduces the incidence of mucosal injury. We experienced a case involving inadvertent retropharyngeal placement of a PFT tube in a 29-year-old patient during nasotracheal intubation under general anesthesia for elective dental treatment. Despite thermosoftening the PFT tube, expanding the nasal meatus, and ensuring gentle maneuvering, the tube intruded into the left retropharyngeal mucosa. However, the injury was not severe, and the only required treatment was the administration of antibiotics and corticosteroids. Even when a PFT tube is utilized, pharyngeal dissection is possible. When resistance is felt during passing of the PFT tube through the nasopharynx, an alternative method to overcome this resistance should be utilized.
