changes in the light intensity of the Fiberoptic Laryngoscope blade by steam sterilization
Anesthesia & Analgesia, 2007Co-Authors: Tomoki NishiyamaAbstract:BACKGROUND: I investigated the effects of steam sterilization on light intensity of reusable Fiberoptic Laryngoscope blades. METHODS: Six new reusable Fiberoptic Macintosh Laryngoscope blades were steam sterilized. The light intensity was measured, the tip of the blades was photographed, and the light intensity of six new plastic disposable Macintosh Laryngoscope blades was also measured. RESULTS: The light intensity of reusable blades exceeded that of the disposable blades after 20 sterilizations, but was significantly lower after 80 sterilizations. The photographs showed irregular lighting of the blades, which increased with repeated sterilization. CONCLUSIONS: Disposable plastic blades provide more illumination than reusable Fiberoptic blades subjected to repeated sterilization.

laryngeal mask anesthesia with intraoperative laryngoscopy for identification of the recurrent laryngeal nerve during thyroidectomy
Laryngoscope, 2002Co-Authors: Michael C Scheuller, David EllisonAbstract:Objectives/Hypothesis: A critical step in thyroidectomy involves definitive identification of the recurrent laryngeal nerve (RLN). Using the laryngeal mask airway, identification of the RLN can be facilitated by stimulation of the nerve while monitoring vocal cord movement with a Fiberoptic Laryngoscope. We present this technique as an effective and safe means to identify the RLN during thyroid surgery, with significant advantages over existing techniques in appropriately selected patients. Study Design: Retrospective case series. Methods: We performed thyroidectomy on 8 patients (13 RLN identifications) in which laryngeal mask airway anesthesia with Fiberoptic laryngoscopy was used to identify the RLN. Results are reviewed with regard to postoperative vocal cord function, as well as intraoperative and postoperative courses with laryngeal mask airway anesthesia. Results: In all 13 cases in which the RLN was sought, it was definitively identified by witnessing brisk vocal cord movement on a video screen with stimulation of the RLN. No patient had postoperative vocal cord paresis or paralysis. Overall recovery from laryngeal mask airway anesthesia was uneventful and had advantages when compared with general anesthesia with endotracheal intubation. Conclusions: Laryngeal mask airway anesthesia with intraoperative Fiberoptic laryngoscopy to identify the RLN is effective and safe in carefully selected patients. Advantages include decreased postoperative throat discomfort, absence of coughing during emergence from anesthesia, and elimination of the possibility of vocal cord mobility impairment secondary to RLN ischemia from the endotracheal tube balloon. In addition, this technique is applicable in operations besides thyroid surgery, in which definitive identification of the RLN is indicated.

A technique for visual confirmation of intrathoracic placement of tube thoracostomy using a Fiberoptic Laryngoscope in a cadaver
European Journal of Trauma and Emergency Surgery, 2015Co-Authors: J. M. Aho, R. K. Ruparel, H. J. SchillerAbstract:Purpose Safe intrathoracic placement of chest tubes is a continual challenge. Current techniques for determining the intrathoracic location of the thoracostomy site include blunt dissection and digital exploration, with subsequent tube placement. Using current techniques, complication rates for this procedure approach 30 %. We present a novel technique using available endotracheal intubation technology for determining intrathoracic placement of tube thoracostomy. Methods One cadaver was used for placement of tube thoracostomy. Both sides of the thorax were prepared in the standard fashion for tube thoracostomy placement, and tube thoracostomy was performed on each hemithorax at interspaces 3 through 7. The right side of the thorax was used for standard thoracostomy placement, and the left side was used for Fiberoptic visualization of thoracostomy placement using a video Laryngoscope. Thoracic wall thickness was measured at all thoracostomy sites. Proper placement and any injuries were documented for each site. Results Chest wall thickness ranged from 2.4 to 3.8 cm on the right and 2.8 to 4.0 cm on the left. With use of Fiberoptic thoracostomy, no injuries were generated. During the standard thoracostomy placement in the sixth intercostal space, a pulmonary laceration was caused using blunt dissection. Conclusions Use of a Fiberoptic Laryngoscope offers a novel technique for direct visualization the thoracic space during tube thoracostomy. Further studies are needed to determine the safety of this technique in patients.

chondrolaryngoplasty under general anesthesia using a flexible Fiberoptic Laryngoscope and laryngeal mask airway
Archives of Otolaryngology-head & Neck Surgery, 2008Co-Authors: Jeffrey H Spiegel, Gerardo RodriguezAbstract:Objectives To describe a surgical and anesthetic technique for chondrolaryngoplasty (“tracheal shaving”) involving external translaryngeal needle insertion under general anesthesia, using a flexible Fiberoptic bronchoscope and laryngeal mask airway. Design Retrospective review of 31 patients who underwent chondrolaryngoplasty performed by a single surgeon. Setting Academic medical center. Patients Thirty-one consecutive patients presenting for aesthetic treatment of their thyroid cartilage. Results The procedures were all successful, with no voice complications and only 1 transient anesthetic complication. Conclusion Chondrolaryngoplasty with translaryngeal needle placement to identify the level of the anterior commissure is a safe, effective surgical technique that minimizes the most significant risks of the surgical procedure.
