Background and Aims: Awake fibre-optic intubation (AFOI) is an integral part of anaesthetic management of difficult airways. Conscious sedation is essential to assist AFOI. This study compared two different doses of dexmedetomidine in combination with topical spray and airway blocks for awake orotracheal fibre-optic intubation in patients undergoing elective cervical spine surgery with rigid cervical collar in situ . Methods: A randomized, prospective, comparative study design was conducted in sixty patients divided into two groups: Group (L) ( n = 30) patients received low dose of dexmedetomidine (0...

Bravo® capsule (BC) (Medtronic, Minneapolis, MN) endoscopy is a reliable, viable, and well-tolerated diagnostic modality for resistant gastroesophageal reflux disease (GERD). Common complications of the procedure include early dislodgment, poor transmission, and premature removal due to intractable pain, while aspiration of the capsule is exceedingly rare. This paper reports a case of BC aspiration in a 52-year-old female who presented after being ventilated when her oxygen saturation dropped. The initial chest radiograph revealed that the BC was in the right main bronchus; the site was further elaborated by flexible endoscopy and the capsule was found to be in the right lower lobe bronchus distal to the bronchus intermedius...

OBJECTIVES: The management of paediatric airway stenosis is complex, and requires a dedicated team, consisting of thoracic surgeons, phoniatricians, logopaedics, paediatricians and anaesthetists. The majority of paediatric laryngotracheal stenosis is a sequela of prematurity and prolonged post-partal intubation/tracheostomy. Surgical correction is often difficult due to a frequent combination of glottic and subglottic defects. METHODS: In 2012, the Laryngotracheal Program Vienna was launched...

Subglottic stenosis is among the most common causes of airway obstruction in children, 90% of which resulting from endotracheal intubation. The diagnosis is based on the patient's clinical, radiologic evaluation, flexible laryngoscopy and rigid airway endoscopy under general anesthesia. It must be suspected in children with respiratory distress after extubation. The therapeutic approach depends on the severity of the subglottic stenosis and the patient's symptoms. We describe our experience with the subglottic stenosis etiologies, diagnosis, treatment and outcome of patients with this condition...

BACKGROUND: Tracheal follicular pattern or so-called tracheal cobblestoning is a poorly described entity in the literature and is depicted as a nodular or lumpy appearance of the tracheal wall mucosa suggesting tracheal irritation from factors like gastro-esophageal reflux (GERD) or pulmonary infection. The aim of the present study was to investigate the prevalence and characteristics of tracheal cobblestones in a large pediatric population. METHODS: A large database of rigid tracheoscopies recorded in children (0-6 years of age) undergoing general anesthesia with planned tracheal intubation for elective surgical procedures was retrospectively analyzed...

BACKGROUND: Despite numerous attempts, synthetic materials and heterologous tissues failed to replace durably the trachea. Autologous tracheal substitution (ATS) without synthetic material or immunosuppression was investigated to replace extended tracheal defect. We present our experience regards to this innovative challenge. METHOD: After a previous research study, we developed a novel reconstruction technique for extended tracheal defects on animals. Through a single stage operation, a tube from a forearm free fascio-cutaneous flap vascularized by radial vessels is re-anastomosed to cervical vessels...

BACKGROUND: Cricopharyngeal foreign bodies (FBs) impaction in adults is a common clinical problem; without treatment, the sequelae may be lethal due to local and/or mediastinal infection. When direct laryngoscopy and flexible fiberoptic endoscopy are ineffective, rigid endoscopy is the method of choice requiring general anesthesia. The new video laryngoscopes represent a great advancement in the assessment of the laryngeal inlet. Aim of the study was to assess the feasibility of identifying and removing FBs impacted at crycofaringeal and upper oesophageal sphincter by the video laryngoscope...

We describe two patients with laryngeal cyst who underwent microlaryngeal surgery. Peroral rigid laryngoscopy, as an indirect endoscopy, performed via the transoral route, was evaluated as a routine screening tool of the difficult airway in patients with laryngeal neoplasm, in our hospital preoperatively. Peroral rigid laryngoscopy had led to two different procedures: One patient was misdiagnosed as having a difficult airway by the ear, nose and throat surgeon resulting in an unnecessary awake tracheotomy. The other patient was found to be with an unanticipated difficult intubation following routine anaesthesia, successful on the third attempt...

We report the successful use of a 2-mm rigid Bonfils intubation endoscope as a rescue device in a 5-week-old baby presenting with an unstable airway due to massive macroglossia and multiple hemorrhagic lymphangiomata compressing the airway and resulting in a Cormack and Lehane grade 4 view. The limited intraoral space rendered it impossible to visualize the laryngeal inlet or insert a laryngeal mask, Glidescope or Airtraq blade into the patient's mouth. A 2-mm Bonfils fibrescope passed easily into the patient's mouth and facilitated a grade 1 view of the laryngeal inlet with subsequent successful intubation at first attempt with a 3...

BACKGROUND: It is important to determine the size and proportion of the larynx as such information is useful in procedures such as intubation, endoscopy and surgical manipulations. Recent interest in the cases of subglottic stenosis and postintubational stenosis of the lower respiratory tract has led to renewed interest in ascertaining the measurements of the various laryngeal cartilages. The aim of the present study was to collect morphometric data of cricoid cartilage from a regional population...

BACKGROUND: Airway alterations found after endotracheal intubation are usually associated with mechanical trauma from the tube. However, no studies are available concerning alterations in airways that have never been intubated before. It was the aim of the study to compare endoscopic findings in the larynx and trachea of children who had undergone prior endotracheal intubation with findings in children who had not been intubated before. METHODS: In 1021 children aged from 0 to 6 years, rigid endoscopies were performed before planned elective endotracheal intubation...

BACKGROUND: The use of a flexible or rigid fiberoptic bronchoscope belongs to the standard repertoire in anesthesiology. Besides a lack of training these procedures may be considerably compromised by endoscopic lens fogging. Several antifogging approaches are commercially available but to date no controlled studies regarding the efficacy of these devices in bronchoscopes exists. The aim of the present study was to compare the efficacy of different commercially available anti-fogging techniques for rigid and flexible bronchoscopes...

Children swallow coins more than any other object. Many methods for removal of impacted coins at the upper end of the oesophagus are enumerated in literature, each having it's own merits and demerits. This retrospective study in 100 consecutive paediatric patients presents a magill forcep technique for removal of coins under inhalational anaesthesia using Mc-Intosch laryngoscope. Intubation and rigid endoscopy both were avoided, thereby minimizing hospital stay and cost of treatment. This also decreases the chances of complications...
