SCIWOCTET is a cervical spine injury (CSI) with objective signs of myelopathy, due to trauma, without evidence of ligament injury or bone fractures on x-ray and computed tomography (CT) images. It is rare, found in about 3% of patients with CSI. Perioperative manipulation of these patients may cause secondary spinal cord injury. The challenge for the anesthesiologist is to manage an airway with as little movement of the patient\'s head and neck as possible. A patient is presented after a fall from a motorbike. At hospital admission, he had neurological deficit in the innervation area of the cervical spinal cord. Multi-slice CT of the head and cervical spine was without signs of acute bone trauma. Magnetic resonance imaging was performed and the diagnosis met the criteria defining SCIWOCTET. Elective cervical spine surgery under general anesthesia was performed, the patient was intubated with a rigid bronchoscope using manual in-line immobilization. The selection of instruments and procedures is emphasized. Other procedures, techniques and instruments that can be used for airway management and their influence on the movement of the patient\'s head and neck are listed. It is concluded that rigid bronchoscopy with the application of manual in-line immobilization is suitable for emergency and elective intubation of patients with cervical spine pathology.

UNASSIGNED: A difficult airway is one of the main causes of morbidity and mortality in patients who undergo surgical interventions. Therefore, many devices and algorithms have been developed for the management of a difficult airway. However no study has been conducted comparing Frova catheter (FC) and a Bonfils fiberoscope (BF) to date.
UNASSIGNED: To compare the effectiveness and success of two devices, a FC and BF, in difficult intubation cases.
UNASSIGNED: Design: Single-centre randomized controlled trial in patients with difficult airways. The assignment order was created by unplanned number charts, and the assignment was hidden in closed covers, which were not unlocked until case permission had been provided. Setting: The trial was undertaken in a university hospital in Turkey. The primary analysis was based on 60 participants (n = 30, n = 30) with difficult intubation. The main outcomes were the success rates of placement of the tracheal tube in the trachea and the duration of the tracheal intubation process.
UNASSIGNED: In the BF group, successful intubation was carried out in 25 of the 30 (83.3%) patients, whereas intubation was successful in 28 of the 30 patients (93.3%) in the FC group. Patients who could not be intubated with the first device were intubated with the other device. The mean duration of intubation was 109 (85-140) s in the BF group, whereas it was 38.8 (26-60) s in the FC group.
UNASSIGNED: Both devices were successful in difficult intubation cases. However, given the shorter duration of intubation using the FC and its lower cost as compared with that of the BF, the FC can be considered superior to the BF in difficult intubation cases.

Direct laryngoscopy (DL) produce tachycardia and hypertension that could be fatal in a patient with a brain injury. Bonfils fiberscope and C-MAC videolaryngoscope are associated with little hemodynamic instability compared to DL. Scientific evidence comparing these two alternatives does not exist. We conducted this study to determine the hemodynamic effects of Bonfils compared to C-MAC in patients undergoing elective surgery.
Fifty (50) patients listed for elective surgery were randomly assigned to endotracheal intubation with Bonfils or C-MAC. After a standardized induction, intubation was done via the retromolar approach (Bonfils group) or via videolaryngoscopy (C-MAC group). A research assistant, who was not blinded to the intervention, recorded heart rate (HR) and arterial blood pressure (systolic, diastolic and mean arterial blood pressure [MAP]) at induction and at every minute during the 5 min post intubation. The primary outcome was the hemodynamic response to intubation, as verified every minute for the first 5 min compared to baseline value.
After randomization, the two groups were comparable except for ASA I/II ratio which was slightly higher in the C-MAC group (p = 0.046). Heart rate (p = 0.40) and MAP (p = 0.30) were comparable between the two groups within 5 min post intubation. Intubation time was shorter with C-MAC than with Bonfils (30 ± 2 s vs 38 ± 2 s; p = 0.02).
Hemodynamic responses to tracheal intubation using the Bonfils fiberscope is comparable to the C-MAC videolaryngoscope among patients scheduled for an elective surgery. In light of these findings, using either technique appears to be a reasonable course of action.

BACKGROUND: Pediatric otolaryngologists are frequently called to assist in difficult airway management in newborns with Pierre Robin Sequence (PRS) who have microretrognathia, glossoptosis, and an anterior larynx. The Bonfils fiberscope (BF) is a curved rigid scope designed to provide superior visualization in the anterior larynx.
OBJECTIVE: (1) to assess whether BF provides an improvement in intubation success rate, time to intubation, or airway visualization as compared to rigid fiberscope (RF) in a difficult airway simulation setting and (2) to determine whether a training program for BF can improve time to intubation through practice trials.
METHODS: Six right-handed trainees completed five trials on each of the three following airway models using the BF and RF: normal anatomy, anterior larynx and PRS. The normal larynx model was intubated only with RF. Main outcome measures were the time needed for tracheal intubation and Cormack-Lehane classification (1-4).
RESULTS: The majority of the intubation trials showed a statistically significant difference between first and last completion times (p < .05) suggesting construct validity. Only the anterior larynx trials with BF did not demonstrate an improvement in time to intubation between first and last attempts (p < .3125). For the PRS retrognathia model, there was no statistically significant difference in time to intubation between using the BF and the RF (p < .44); in the anterior larynx model, the RF yielded a faster time to intubation than the BF on the final trial attempts (p < .0313). By Cormack-Lehane classification measures, laryngeal visualization by the BF was better than RF in the PRS manikin (p < .0022) while there was no significant difference in grade scores for the anterior larynx manikin (p < .45). All six trainees reported an improved visualization of the larynx with the BF compared to the RF for both the anterior larynx and PRS manikins; at the end of the trial runs, all participants noted an improvement in comfort level using the BF.
CONCLUSIONS: The difficult airway simulation model is feasible for surgical training. BF adds superior visualization of the anterior larynx in PRS. Otolaryngology training programs may include BF as a supplemental tool in addition to RF as a part of the airway equipment training since there is significant improvement in time to intubation with consecutive practice trials and superior laryngeal visualization.

OBJECTIVE: This study aimed to determine the effectiveness, safety, and oral intubation time (IT) using a retromolar Bonfils fiberoptic scope compared with a conventional Macintosh laryngoscope.
METHODS: Sixty patients (16-60 years old, American Society of Anesthesiology I/II) scheduled for general anesthesia for elective ear-nose-throat and plastic surgery were randomly divided into a Bonfils group (Group B, n = 30) and a Macintosh group (Group M, n = 30). Exclusion criteria included Mallampati IV, thyromental distance ≤4 cm, mouth <4 cm, cervical spine problems, body mass index >35, sleep apnea, reflux esophagitis, coronary artery disease, intracranial vascular malformation, elevated intracranial pressure, bleeding disorders, allergies to planned drugs, and patient refusal. Mallampati scoring, mouth opening, and thyromental distance were used for airway assessment. The time needed for successful intubation (IT), number of attempts, number of failures, systolic (SBP), diastolic (DBP), mean blood pressure (MBP), heart rate (HR) and Oxygen saturation (O2) and damage to the lips, dentures, and pharyngeal or laryngeal structures were recorded. Continuous variables are presented as mean ± standard deviation and categorical variables are presented as frequency and percentage. Chi-square tests and Student\'s t-tests were used to compare the groups. P < 0.05 was considered statistically significant.
RESULTS: The groups were comparable regarding demographic data, preoperative airway parameters, IT, the number of attempts, O2, and the incidence of complications (P > 0.05). However, Bonfils intubation was associated with more stable HR, SBP, DBP and MBP (P < 0.05).
CONCLUSIONS: The Bonfils fiberoptic scope is comparable to a Macintosh laryngoscope but assures better hemodynamic stability. In difficult cases, the Bonfils scope is a better choice because of its ability to navigate.

Awake intubation with a flexible fibrescope is usually done electively in patients with a known difficult airway. Herein, we describe the case of an elective awake tracheal intubation that was performed on a patient with a large, obstructive supraglottic mass. The intubation was successfully performed using the Bonfils fibrescope after several failed attempts with a flexible fibrescope. This case highlights the usefulness of the Bonfils fibrescope and the limitations of the flexible fibrescope in certain clinical situations.

The role of various airway adjuncts in the management of difficult airway has been described in the literature. Bonfils rigid fiberscope is one of the airway assist devices widely used for endotracheal intubation in the individuals with cervical instability warranting limited neck movements. With our experience in the utilization of Bonfils for single lumen endotracheal tube placement, we are increasingly using for double lumen endobronchial (DLT) intubation as well. We would like to describe our experience in the use of Bonfils for DLT placement and outline the merits and limitations of the other suitable airway assist devices in this report. The double lumen tube has to be modified by decreasing the length of DLT to accommodate the Bonfils fiberscope and this is applicable only in certain type of double lumen tubes for e.g. Bronchocath.
