Context The Edmonton Symptom Assessment System (ESAS) is one of the most commonly used symptom batteries in clinical practice and research. Objectives We used the anchor-based.approach to identify the minimal clinically important difference (MCID) for improvement and deterioration for ESAS physical, emotional and total symptom distress scores. Methods In this multicenter prospective study, we asked patients with advanced cancer to complete their ESAS at the first clinic visit and at a second visit three weeks later. The anchor for MCID determination was Patient's Global Impression regarding their physical, emotional and overall symptom burden (“better,” “about the same,” or “worse”). We identified the optimal sensitivity/specificity cutoffs for both improvement and deterioration for the three ESAS scores and also determined the within-patient changes. Results A total of 796 patients were enrolled from six centers. The ESAS scores had moderate responsiveness, with area under the receiver-operating characteristic curve between 0.69 and 0.76. Using the sensitivity-specificity approach, the optimal cutoffs for ESAS physical, emotional and total symptom distress scores were ≥3/60, ≥2/20 and ≥3/90 for improvement, and ≤−4/60, ≤−1/20 and ≤−4/90 for deterioration, respectively. These cutoffs had moderate sensitivities (59%-68%) and specificities (62%-80%). The within-patient change approach revealed the MCID cutoffs for improvement/deterioration to be 3/−4.3 for the physical score, 2.4/−1.8 for the emotional score, and 5.7/−2.9 for the total symptom distress score. Conclusion We identified the MCIDs for physical, emotional and total symptom distress scores, which have implications for interpretation of symptom response in clinical trials.

Our outpatient palliative care consultation was associated with improvement in ESAS, particularly for patients who presented with moderate to severe symptoms. Further studies are needed to examine predictors of symptom response, longer term outcomes, and how to improve access to outpatient palliative care in the Middle East.

Imminent upper airway obstruction due to life-threatening tracheal stenosis of any cause is a challenging situation. We present a challenging case of total thyroidectomy for a malignant, invasive, and highly vascularized thyroid carcinoma that has invaded the surrounding tissues, including the sternum and mediastinum, resulting in compression of the trachea with indentation. The patient presented with a significant symptomatic tracheal stenosis, the narrowest area of that was 4 mm. Airway management in such cases presents a particular challenge to the anesthesiologists, especially considering that the option of tracheostomy is very difficult most of the time due to the highly swollen thyroid and distorted anatomy. A meticulous history of the patient's illness had been taken, and a comprehensive preoperative evaluation was conducted, including construction of a 3D model airway, virtual endoscopy, and transnasal tracheoscopy. On the day of the surgery, the airway was managed through spontaneous respiration using intravenous anesthesia and the high-flow nasal oxygen (STRIVE-Hi) technique. It was then secured with intubation using a straw endotracheal tube (Tritube®) with an internal diameter (ID) of 2.4 mm and an outer diameter of 4.4 mm with the help of a fiberscope and D-MAC blade of a video laryngoscope. At the end of the procedure, the airway was checked with a fiber optic scope, which showed an improvement in the narrowed area. This enabled us to replace the Tritube with an adult cuffed ETT of size 6.5 mm ID, and the patient was transferred intubated to the surgical ICU. Two days later, the patient's tracheal diameter was evaluated with the help of a fiberoptic scope and extubated successfully in the operating theater.

This topic aims to discuss key aspects of anesthetic and airway management for head and neck surgery. Airway management is a central part of patient care and management in Head and Neck Surgery. Common challenges in Head and Neck surgery are shared airway, distorted airway anatomy due to existing pathology; risk of airway obstruction, disconnection or loss of airway intra-operatively; risk of soiling of the airway due to bleeding and surgical debris; and the potential for airway compromise post-operatively. The option for airway management technique is influenced by patient’s factors, anesthetic needs, and surgical requirements. Intubation technique necessitating either a small or large cuffed tracheal tube with a throat pack provides the highest level of airway protection Non-intubation or open airway techniques involve mask ventilation, apneic techniques, and insufflation techniques, or the use of a laryngeal mask airway. Lastly, jet ventilation techniques may be conducted via a supraglottic, subglottic or transtracheal routes. It is essential to have clear airway management plans including rescue airway strategies that should be communicated with the surgeons and patients at the earliest opportunity.
