Jiyoung Lee, Jong Yeop Kim, Se Yoon Kang, Hyun Jeong Kwak, Dongchul Lee, Sook Young Lee
BACKGROUND: The McGrath videolaryngoscope (VL) provides excellent laryngoscopic views, but directing an endotracheal tube can be difficult, and thus the routine use of a stylet is recommended. The goal of this study is to determine the appropriate angle (60° vs 90°) of the stylet when using the McGrath VL by comparing the time to intubation (TTI). METHODS: One hundred and forty patients aged 19 to 70 years (American Society of Anesthesiologists classification I or II) who required tracheal intubation for elective surgery were randomly allocated to 1 of 2 groups, at the 60° angle (n = 70) or the 90° angle (n = 70)...

OBJECTIVES/HYPOTHESIS: Current rhinologic practice is devoid of minimally invasive procedures dedicated to the treatment of ethmoid sinusitis to improve ventilation and topical drug delivery. We have recently described a handheld spiral punch to create minimally invasive ethmoid punch sinusotomy (EPS) sites into the ethmoid bulla and basal lamella, which significantly increased irrigant access to the ethmoid sinuses in cadaver models. Here, we conducted a clinical feasibility study to determine the initial safety evaluation of EPS in chronic rhinosinusitis without polyposis (CRSsNP) patients with active ethmoid disease...

BACKGROUND: Securing the airway in severely ill patients is associated with a high rate of complications. So far, no information exists about the equipment readily available for airway management in German intensive care units (ICUs). It is also unknown if the range of material has improved over time. OBJECTIVES: In the present trial the availability of equipment for airway management in ICUs in Rhineland-Palatinate was evaluated at two different times. MATERIALS AND METHODS: Using a structured questionnaire, all ICUs in the state were contacted in the years 2010 and 2015...

OBJECTIVE: The tumor microenvironment frequently displays abnormal cellular metabolism, which contributes to aggressive behavior. Metformin inhibits mitochondrial oxidative phosphorylation, altering metabolism. Though the mechanism is unclear, epidemiologic studies show an association between metformin use and improved outcomes in head and neck squamous cell carcinoma (HNSCC). We sought to determine if metformin alters metabolism and apoptosis in HNSCC tumors. STUDY DESIGN: Window of opportunity trial of metformin between diagnostic biopsy and resection...

STUDY OBJECTIVE: Morbid obesity is associated with a difficult management of the airway. There is no agreement on these patients being difficult to intubate, but if they are difficult to ventilate with facial mask, then the fast control of their airway becomes a priority. This study compares the quickness and success in tracheal intubation, glottic view, hemodynamic response, and complications from the use of the Macintosh and Airtraq laryngoscopes in morbidly obese patients for scheduled surgery...

BACKGROUND: Neonatal endotracheal intubation is a life-saving procedural skill where best practices have been developed from expert opinion. Few empirical studies have examined how this skill should be taught. OBJECTIVE: To determine whether a video laryngoscope (VL) assisted intubation training curriculum compared to a traditional direct laryngoscope (DL) assisted curriculum improves neonatal intubation performance of novice intubators in a simulated setting. METHODS: A randomized trial of novice intubators was conducted at the University of Texas-Houston from 6/2013-8/2013...

OBJECTIVES/HYPOTHESIS: Local anesthetic with epinephrine is commonly injected into the nasal mucosa during functional endoscopic sinus surgery (FESS). Systemic absorption of epinephrine following local injection may occur, resulting in a mild sympathetic response. This study seeks to determine whether an exaggerated sympathetic response to epinephrine is demonstrated in patients undergoing FESS treated preoperatively with established pharmacologic beta (β) adrenoceptor blockade. STUDY DESIGN: A retrospective analysis of adult patients undergoing FESS at a tertiary care university hospital...

Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver)...
