Abstract:
Preoperative laryngoscopic examination of the airway informs general anaesthesia management and planning. However, the same glottic opening view cannot always be obtained during direct laryngoscopy of anaesthetised patients. In this case report, a patient underwent preoperative rigid laryngoscopy due to medical history, and no problems were anticipated in performing tracheal intubation; however, the direct laryngoscopic view was a Grade 4 on the Cormack-Lehane Scale after anaesthesia induction. A jaw thrust manoeuvre to facilitate fibreoptic-assisted nasotracheal intubation was not feasible. In order to compensate, a modified method of jaw thrust was implemented, where both thumbs were placed on the floor of the patient’s mouth, leading to a successful result. Safe airway management should be implemented with proper planning based on a careful preoperative evaluation.

Abstract:
Abstract Background: Research regarding difficult mask ventilation (DMV) combined with difficult laryngoscopy (DL) is extremely limited even though each technique serves as a rescue for one another. Methods: Four tertiary care centers participating in the Multicenter Perioperative Outcomes Group used a consistent structured patient history and airway examination and airway outcome definition. DMV was defined as grade 3 or 4 mask ventilation, and DL was defined as grade 3 or 4 laryngoscopic view or four or more intubation attempts. The primary outcome was DMV combined with DL. Patients with the primary outcome were compared to those without the primary outcome to identify predictors of DMV combined with DL using a non-parsimonious logistic regression. Results: Of 492,239 cases performed at four institutions among adult patients, 176,679 included a documented face mask ventilation and laryngoscopy attempt. Six hundred ninety-eight patients experienced the primary outcome, an overall incidence of 0.40%. One patient required an emergent cricothyrotomy, 177 were intubated using direct laryngoscopy, 284 using direct laryngoscopy with bougie introducer, 163 using videolaryngoscopy, and 73 using other techniques. Independent predictors of the primary outcome included age 46 yr or more, body mass index 30 or more, male sex, Mallampati III or IV, neck mass or radiation, limited thyromental distance, sleep apnea, presence of teeth, beard, thick neck, limited cervical spine mobility, and limited jaw protrusion (c-statistic 0.84 [95% CI, 0.82–0.87]). Conclusion: DMV combined with DL is an infrequent but not rare phenomenon. Most patients can be managed with the use of direct or videolaryngoscopy. An easy to use unweighted risk scale has robust discriminating capacity.

Abstract:
A 47-year-old obese woman with GERD and COPD presents for CO2-laser excision of bilateral vocal fold masses. She had a history of progressive hoarseness and difficulty in breathing. Nasopharyngeal laryngoscopy revealed large, mobile, bilateral vocal cord polyps that demonstrated dynamic occlusion of the glottis. We describe the airway and anesthetic management of this patient with a topicalized C-MAC video laryngoscopic intubation using a 4.5 mm Xomed Laser Shield II endotracheal tube. We examine the challenges of anesthetic management unique to the combined circumstances of a ball-valve lesion and the need for a narrow-bore laser compatible endotracheal tube.

Abstract:
Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background The infant airway is particularly vulnerable to trauma from repeated laryngoscopy attempts. Complications associated with elective tracheal intubations in anesthetized infants may be underappreciated. We conducted this study of anesthetized infants to determine the incidence of multiple laryngoscopy attempts during routine tracheal intubation and assess the association of laryngoscopy attempts with hypoxemia and bradycardia. Methods We conducted a retrospective cross-sectional cohort study of anesthetized infants (age less than or equal to 12 months) who underwent direct laryngoscopy for oral endotracheal intubation between January 24, 2015, and August 1, 2016. We excluded patients with a history of difficult intubation and emergency procedures. Our primary outcome was the incidence of hypoxemia or bradycardia during induction of anesthesia. We evaluated the relationship between laryngoscopy attempts and our primary outcome, adjusting for age, weight, American Society of Anesthesiologists status, staffing model, and encounter location. Results A total of 1,341 patients met our inclusion criteria, and 16% (n = 208) had multiple laryngoscopy attempts. The incidence of hypoxemia was 35% (n = 469) and bradycardia was 8.9% (n = 119). Hypoxemia and bradycardia occurred in 3.7% (n = 50) of patients. Multiple laryngoscopy attempts were associated with an increased risk of hypoxemia (adjusted odds ratio: 1.78, 95% CI: 1.30 to 2.43, P < 0.001). There was no association between multiple laryngoscopy attempts and bradycardia (adjusted odds ratio: 1.23, 95% CI: 0.74 to 2.03, P = 0.255). Conclusions In a quaternary academic center, healthy infants undergoing routine tracheal intubations had a high incidence of multiple laryngoscopy attempts and associated hypoxemia episodes.

Abstract:
Increasingly, third party payers are challenging the necessity of a hospital admission for endoscopic procedures. Direct laryngoscopy (DL), with or without open, rigid esophagoscopy or flexible, fiberoptic bronchoscopy, was evaluated for the incidence of perioperative complications and associated risk factors. A retrospective review of 200 in-patient admissions between 1987 and 1990 for direct laryngoscopy or panendoscopy is presented. Complications were classified as major for untoward events that required hospitailzation for proper management. Complications were otherwise considered minor. The incidence of major complications was at least 19.5%, with minor complications occurring in 21% of patients. The total population was partitioned into subsets according to the occurrence of major complications, minor complications, and no complications. For the total population and each subset, distributions were developed by age, sex, habitus, physical status level, diagnosis of molignancy, presence of a malignant lesion in the aerodigestive tract, or medical history of head and neck surgery or radiation therapy. Statistical analysis indicates that these parameters do not offer reliable predictors of which patients are at risk for minor or major complications. It is concluded that all patients who undergo direct laryngoscopy are most safety managed in an in-hospital setting for a period on the order of 24 hours.

Abstract:
Objective Postoperative pain is an important part of the patient’s surgical experience. The objective was to evaluate patient perception and duration of pain after microdirect laryngoscopy (MDL). Study Design Case series with planned data collection. Setting Tertiary care, academic center. Subjects and Methods Adult patients undergoing MDL were administered the short-form McGill Pain Questionnaire (SF-MPQ) before surgery and on postoperative days (PODs) 1, 3, and 7. Demographic and clinical data were collected. Results In total, 130 patients (mean age 52.6 years, 84 male) participated in the study. About 46.2% required analgesia on POD 1, but only 23.1% required opioids. Overall, mild levels of pain were reported on the SF-MPQ: sensory score, affective score, total score, present pain intensity (PPI), and visual analog scale (VAS). Patients reported a significant increase in pain on POD 1, with decreases in pain on PODs 3 and 7. Pain score returned to preoperative values for total score and affective score on POD 7 but remained significantly elevated for PPI, VAS, and sensory score. None of the following factors were associated with increased pain: age, sex, body mass index, Mallampati score, Cormack score, laryngoscope used, type of MDL, time under anesthesia, employment status, intubation, Voice Handicap Index 10, and chronic pain history. Conclusion Although mild levels of pain were reported after MDL, the pain persisted for up to 7 days. No demographic or clinical factors were found to be associated with increased pain. This study was one of the few prospective studies evaluating pain after MDL.

Abstract:
Background: The prevalence of opioid abuse has become epidemic in the United States. Microdirect laryngoscopy (MDL) is a common otolaryngological procedure, yet prescribing practices for opioids following this operation are not well characterized. Objective: To characterize current opioid-prescribing patterns among otolaryngologists performing MDL. Methods: A cross-sectional survey of otolaryngologists at a national laryngology meeting. Results: Fifty-eight of 205 physician registrants (response rate 28%) completed the survey. Fifty-nine percent of respondents were fellowship-trained in laryngology. Respondents performed an average of 13.3 MDLs per month. Thirty-four percent of surgeons prescribe opioids for over two-thirds of their MDLs, while only 7% of surgeons never prescribe opioids. Eighty-eight percent of surgeons prescribed a combination opioid and acetaminophen compound, hydrocodone being the most common opioid component. Many surgeons prescribe non-opioid analgesics as well, with 70% and 84% of surgeons recommending acetaminophen and ibuprofen after MDL respectively. When opioids were prescribed, patient preference, difficult exposure and history of opioid use were the most influential patient factors. Concerns of opioid abuse, the physician role in the opioid crisis, and literature about postoperative non-opioid analgesia were also underlying themes in influencing opioid prescription patterns after MDL. Conclusions: In this study, over 90% of practicing physicians surveyed are prescribing opioids after MDL, though many are also prescribing non-opioid analgesia as well. Further studies should be completed to investigate the needs of patients following MDL in order to allow physicians to selectively and appropriately prescribe opioid analgesia postoperatively.

Abstract:
This chapter describes a presurgical protocol for patients with moderate to severe obstructive sleep apnea (OSA) who plan to undergo treatment with upper airway stimulation (UAStim). Patients must receive an initial evaluation including a medical and sleep history and physical examination focused on characteristics suggestive of upper airway narrowing. Criteria related to UAStim therapy and possible exclusion from implantation may be considered at this point. Some patients may be referred to a sleep specialist, but all must undergo in-laboratory or at-home polysomnography to diagnose OSA. Following an OSA diagnosis, treatment with continuous or auto-titrating positive airway pressure should be initiated. Unfortunately, CPAP adherence is low, and while there are several nonsurgical alternatives, many patients who are unable or unwilling to use CPAP will seek surgical treatment. Patients who are referred to otolaryngology for evaluation for UAStim therapy should undergo a medical and sleep history and physical examination including flexible fiberoptic laryngoscopy to evaluate upper airway anatomy. Patients must next undergo drug-induced sleep endoscopy (DISE), during which the upper airway is directly visualized in the operating room with fiberoptic endoscopy under sedation. The most common classification system to describe the location and pattern of upper airway collapse observed during DISE is the Velum, Oropharyngeal walls, Tonsils, Epiglottis (VOTE) system. Patients older than 22 years of age, with an apnea–hypopnea index between 15 and 64 (with central/mixed apneas &lt;25% of the total), a body mass index &lt;32 m/kg<sup>2</sup>, and without palatal complete concentric collapse may be offered UAStim treatment.
