[Tracheal stenosis following direct laryngoscopy].

The appearance of progressive and disabling dyspnoea in a 58 year old lady, beginning three months after direct laryngoscopy (LD) led to a pulmonary function assessment after six months of mistaken diagnoses. The flow/volume (V/V) curves were characteristic of a high fixed obstruction. Fibreoptic endoscopy showed a non-neoplastic stenosis by a sub-glottic diaphragm. The stenosis was treated in a lasting fashion using a Yag laser (Medilas 2). Other than a congenital stenosis presenting in adulthood, the only cause that can be considered is a traumatic stenosis (post-LD) on an inflamed larynx. Such an aetiology for tracheal stenosis has never, to our knowledge, been described. Even if this type of stenosis is extremely rare, the possibility should not be ignored.

Ventilation during laryngoscopy in chronic obstructive lung disease.

Many patients requiring direct examination of the upper airway and gastrointestinal tract under general anesthesia have chronic obstructive lung disease, yet virtually no work has been done to assess the adequacy of their ventilation during laryngoscopy and in the early postoperative period. This study demonstrates that, using the Carden tube, their blood gases are well maintained even when areas outside the endolarynx, such as the upper esophagus, are examined. The Carden tube is shown to be easy to insert and remove as well as permitting a superior view of the larynx. Also, this study pinpoints the period of maximum danger of respiratory failure as occurring postoperatively in the recovery room. This should be independent of the method of ventilation employed at surgery and indicates the need for cocainization of the vocal cords before extubation, as well as careful, early postoperative monitoring. The problems of ventilation during direct examination of the upper airway and gastrointestinal tract are discussed and alternative methods evaluated.

Recent advances in operative laryngoscopy.

Multiple techniques of operative laryngoscopy are currently available. It behooves the otolaryngologist to be knowledgeable about several methods in terms of their relative merits. In this way the anesthetic and lighting technique of choice can be used for the particular lesion and procedure planned.

The value of capnography during jet ventilation for suspension laryngoscopy.

A self made connection device with an injector of 1.5 mm in diameter and connections for the measurements of the end tidal CO2 (Datascope 500 CO2 Analyzer), expired tidal and minute volumen (Dr¿ger Spirolog), and armoured tracheal tube nr. 22 with cuff (Rüsch), has been used in 25 unselected patients submitted to diagnostic laryngoscopy. The patients have been ventilated with Wolf Injectomat 2025 with incorporated Bird's Nitrous Oxyde/Oxygen blender and general anesthesia with i.v. hypnoticum (Penthotal or Hypnomidate), analgeticum (Fentanyl) and muscle relaxant (Curalest) has been used. The patients were further monitored by means of blood pressure measurements (oscillotonometric method), simultaneous pulse count and ECG recording (Datascope 740 Recorder) and blood gases determination from a.femoralis (ABL 1, Radiometer Copenhagen).

Video laryngoscopy.

New techniques for visualing the upper and part of the lower airway provide for efficient assessment of airway dysfunction. Equipment is available for video recording during the assessment, which can be done either in the caregiver's office/clinic or during stress testing in an exercise facility. Case reports that illustrate the diagnostic use of video laryngoscopy as well as adjunct to therapy are presented in this article.

[May recurrent goiter be resected bilaterally? Value and results of intraoperative laryngoscopy].

Operations for recurrent goiter are considered to range among the most difficult procedures in thyroid surgery and are marked by unusually high subsequent damages of the recurrent nerve. Results from 89 patients with recurrent goiter operated over the last six years and our own experiences with intraoperative laryngoscopy are presented. This procedure is applicable in 60% of all cases with true bilateral thyroid recurrency and accounts for a realistic help in deciding whether to continue the operation with simultaneous resection of the contralateral side.

[Use of propofol (diprivan) for induction of anesthesia in neurosurgical patients. I. Pressor reaction to laryngoscopy and intubation of the trachea].

Pressor reaction to laryngoscopy and intubation of the trachea was studied in 32 patients with neurosurgical diseases of the brain (supratentorial tumors and arterial aneurysms) under conditions of induction anesthesia with propofol (diprivan) in the mean dose of 2.85 mg/kg. Diprivan alone did not block the development of pronounced pressor reaction to intubation. Combination of diprivan in the same dose with dipidolor (0.4 mg/kg) ensured complete blocking of the pressor reaction in neurosurgical patients. Combination of diprivan and fentanyl (2.85 mg/kg) blocked the development of a pressor reaction not so effectively and not in all the examinees.

Asystole following laryngoscopy and endotracheal intubation: a case report.

Severe bradycardia and asystole are very rare complications following laryngoscopy and endotracheal intubation. In this report, we describe a case in which these life-threatening complications occurred in a healthy male during induction of general anaesthesia. Activation of vagal reflexes during manipulation of the airway and the use of vagotonic drugs at induction are the mechanisms postulated to be responsible for these phenomena. Analysis of heart rate variability measurements may be useful in identifying patients at risk for development of these haemodynamic alterations during the induction of anaesthesia so that appropriate drugs and monitoring can be administered.

[Inflation of the endotracheal tube cuff as an aid for blind nasotracheal intubation in patients with predicted difficult laryngoscopy].

HYPOTHESIS AND OBJECTIVES: Inflation of the tracheal tube cuff to facilitate blind nasal intubation as described by Gobarck in 1987 has been shown to be effective for increasing the rate of successful intubation from 45 to 95% in patients with no airway alterations. We aimed to assess the usefulness of this technique in patients with anatomical alterations of the airway, in whom difficult intubation was predicted. PATIENTS AND METHODS: We enrolled 25 patients with airway alterations that made laryngoscopy likely to be difficult and who were scheduled for neoplastic maxillofacial surgery. RESULTS: Twelve patients (48%) were intubated on the first try, 5 (20%) on the second try and 6 (24%) on the third try. We were unable to intubate 2 patients (8%) after three tries, and therefore opted to intubate with a fiberoptic endoscope. CONCLUSIONS: Inflation of the tracheal tube cuff is useful for facilitating nasotracheal intubation in the awake patient.

Inhaled lidocaine for prevention of hemodynamic changes in laryngoscopy and intubation.

This study was undertaken to examine the efficacy of lidocaine aerosol pretreatment in attenuating hemodynamic (HD) responses secondary to laryngoscopy and tracheal intubation in patients undergoing surgery for intracranial space occupying lesions (ICSOL). A semiclosed breathing system was improvised to generate aerosol of consistent density. Five percent lidocaine was nebulized in two different dosages (0.2 and 0.1 ml/kg in groups A and B, respectively); group C (control) received aerosol of normal saline. The average aerosol-treatment time was 24, 12, and 16 min in groups A, B, and C, respectively. Changes in heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), and rate pressure product (RPP) were analyzed by analysis of variance (ANOVA). In group A, tracheal intubation did not cause significant HD changes. In group B, a significant increase was observed in each HD parameter which, when compared with control, was less severe. Lidocaine toxicity, regurgitation, nausea, vomiting, or aspiration did not occur in any patient. Patients accepted the procedure well. This study found efficacy of the technique to be related to duration of aerosol treatment.

Evaluation of the Bullard laryngoscope using the new intubating stylet: comparison with conventional laryngoscopy.

The Bullard laryngoscope (BL) is a new device for managing the difficult airway. Previous publications on the BL are primarily descriptive, and fail to use internal controls (i.e., determine the best intubating mechanism) or external controls (i.e., compare the BL to a known standard such as conventional laryngoscopy). Therefore, we attempted to determine the best of four intubating mechanisms described for the BL (independently styletted endotracheal tube [ETT], the Bullard intubating forceps, an ETT with a directional tip or the new dedicated intubating stylet) and to determine whether time to successful intubation with the BL using the best intubating mechanism correlates with conventional grade of laryngoscopic view. The new intubating stylet provided the optimal intubating method; fewer attempts were required (1.1 vs 1.7, P = 0.005), and it took less time to successful tracheal intubation (39 +/- 34 s vs 83 +/- 74 s, P = 0.004) compared to the three other intubating mechanisms. Our results also suggest that the time to successful intubation with the BL using the intubating stylet was not affected by the conventional laryngoscopic grade; it was just as easy (and difficult) to intubate a conventional Grade I laryngoscopic view patient (full glottic view) as it was to intubate a conventional Grade III laryngoscopic view patient (visualization of just the epiglottis) with the BL. There were two failed intubations with the BL (3%) due to an inability to trap the epiglottis.(ABSTRACT TRUNCATED AT 250 WORDS)

Laryngoscopy in neonates and infants: experience with the flexible fiberoptic bronchoscope.

A small flexible fiberoptic bronchoscope was used for laryngeal examination in a series of neonates and infants; 104 laryngoscopies were performed in 59 patients. A high yield of diagnostic information was obtained in both postextubation patients and patients presenting with upper airway obstruction. No major complications were observed. This technique is useful in the evaluation of neonates and infants with potential upper airway problems.

Direct Laryngoscopy in Mice.

This report describes a noninvasive method for direct laryngoscopy in mice as small as 20 g by using commercially available equipment. A pediatric otoscope is inserted into the mouth of an anesthetized mouse to provide a clear view of the vocal cords. The procedure takes less than a minute and has been successful without complications in the 65 mice studied to date. The technique can be used to instill test substances into the lungs or to perform oral endotracheal intubation for resuscitation, airway support, or controlled ventilation.
