Acute Awake Fiberoptic Intubation in the ICU in a Patient with Limited Mouth Opening and Hypoxemic Acute Respiratory Failure

Airway Management Failure after Delayed Extubation in a Patient with Oral Malignant Melanoma Who Underwent Partial Mandibulectomy and Reconstruction with a Free Flap

Maxillofacial surgery may cause severe complications in perioperative airway management. We report a case of failed airway management in a patient who underwent segmental mandibulectomy, radical neck dissection, and reconstruction with a free flap. The patient was extubated approximately 36 hours after surgery. Approximately 7 hours after extubation, the patient complained of dyspnoea, and respiratory failure followed. Bag-mask ventilation, direct laryngoscopy, video laryngoscopy, and supraglottic airway access were ineffective. The surgical airway was secured with an emergency tracheostomy while performing cardiopulmonary resuscitation. However, the patient experienced permanent hypoxic brain damage. The airway of patients with oral cancer may be compromised postoperatively due to surgical trauma and bulky flap reconstruction. Patients should be closely monitored during the postoperative period to prevent airway failure. Early diagnosis and airway management before airway failure occurs are important. Medical staff should be aware of airway management algorithms, be trained to perform difficult airway management, and have the required equipment readily available.

Managing Known Difficult Airways in Obstetric Patients Using a Flexible Bronchoscope and IRRIS: A Case-Illustrated Guide for Nonexpert Anesthesiologists, without Surgical Backup

Pregnancy is associated with anatomical and physiological changes leading to potential difficult airway management. Some pregnant women have known difficult airways and cannot be intubated even with a hyperangulated videolaryngoscope. If neuraxial techniques are also impossible, awake tracheal intubation with a flexible bronchoscope may be one of the few available options to avoid more invasive techniques. The Infrared Red Intubation System (IRRIS) may help nonexpert anesthesiologists in such situations and may enhance the chance of successful intubation increasing safety for the mother and the fetus, especially in hospitals without the ear, nose, and throat surgical backup.

Diagnosis and management of temporomandibular joint dysfunction before surgery: a case report

We present a case of colorectal cancer with temporomandibular joint dysfunction and discuss the management of the case. Type IIIb temporomandibular disorder involves anterior dislocation of the articular disk, trismus and difficult intubation. A 68-year-old woman was scheduled for colectomy. The day before surgery, the patient had temporomandibular pain. On examination, the mouth opening was 13 mm. We diagnosed type IIIb temporomandibular disorder. A simple splint was fabricated with gauze and she bit it. The mouth opening was 55 mm on the day of surgery. The pain disappeared, and intubation was uneventful. Temporomandibular disorders are generally treated by dentists. It is beneficial for general hospitals without a dentistry department to employ a dental anaesthesiologist to assist in potentially difficult intubations in patients with temporomandibular disorders.
