Optic Internal Urethrotomy Under Transrectal Ultrasonographic Guide And Suprapubic Fiberoscopic Aid
The Journal of Urology, 1994Co-Authors: Cheng-keng Chuang, Ming-kuen Lai, Sheng-hsien ChuAbstract:Optic internal urethrotomy is the initial treatment of choice for most urethral strictures because of the relatively low morbidity and ease of accomplishment. However, the procedure is difficult and frustrating if a severe stricture or complete disruption of the urethra is encountered. Transrectal ultrasonography of the urethra offers good anatomical visualization, and defines the exact length and extent of bulbous and posterior urethral strictures, which could ensure a more accurate and aggressive incision of the stricture. Eleven patients (8 with posttraumatic and 3 with iatrogenic strictures) with complete obliteration of the bulbous and posterior urethra were successfully treated by optic internal urethrotomy with the aid of transrectal ultrasonography and a suprapubic fiberscope. After 1 year of followup, 5 of the 8 posttraumatic urethral strictures required further management, while the remaining patients had satisfactory results. Although the recurrence rate is high in the posttraumatic patients, transrectal ultrasound and the suprapubic Fiberoscope afford a reliable and satisfactory aid during optic internal urethrotomy.

Tracheal intubation in a case of Still's disease
Minerva anestesiologica, 1995Co-Authors: A Carlot, Gallo F, Alberti A, A Fongaro, Valenti SAbstract:The authors report the case of a patient with juvenile rheumatoid arthritis (Still's disease) who underwent laparotomic hysterectomy under general anesthesia. Tracheal intubation was performed with the aid of a fibroscope, as recommended in the literature, given that impairment of the cervical spine and the temporo-mandibular joint made it extremely unlikely that direct laryngoscopy could be performed. The authors also report the methods recommended by other authors in order to guarantee a sufficiently deep anesthetic plane together with patency of the airways in patients suffering from Still's disease.

Using a nasopharyngeal airway during fiberoptic intubation in small children with a difficult airway.
Paediatric anaesthesia, 2005Co-Authors: Rolf Holm-knudsen, Kirsten Eriksen, Lars S. RasmussenAbstract:Summary Background : Induction of anesthesia and tracheal intubation in small children with a difficult airway is a challenging task. We report the experience with a procedure based on sevoflurane inhalation via a nasopharyngeal airway inserted early during induction before airway obstruction occurs. A pediatric fiberscope is used to perform a nasotracheal intubation via the opposite nostril. Methods: All small children with suspected or known difficult airway needing tracheal intubation were scheduled for a fiberoptic intubation following the described protocol. Results : In 3 years, we performed 27 successful fiberoptic guided tracheal intubations in 19 children, median age 8.2 months (1.0–39.1 months) and median weight 7.6 kg (3.0–15.0 kg). The optimal depth for placement of the nasopharyngeal airway was found to be 8.0 cm (7.0–8.5 cm) from the nostril in the first year of life and 8.5 cm (8.0–10 cm) in the second year. Oxygenation was sufficient during the entire procedure in all cases except one child who had short-lasting laryngeal spasm caused by instillation of lidocaine during light anesthesia. The duration of fiberoptic intubation was significantly shorter when performed by an experienced anesthesiologist (55 s vs. 120 s), but there was no significant correlation between the duration of fiberoscopy and oxygen saturation during fiberoscopy or endtidal CO2 after intubation. Conclusion : The combination of nasopharyngeal airway and fiberoptic guided tracheal intubation seems to be a reliable and safe procedure for managing the difficult airway in small children.

Difficult intubation of the esophagus or trachea stent – When cervical muscle contractures combined with the narrowing. Descriptions of cases
European Respiratory Journal, 2011Co-Authors: Adam Rzechonek, Jerzy KołodziejAbstract:Purpose: The muscle contraction is the main cause of difficulty of tracheal intubation. Self-expanding tube stents are typically placed using a rigid bronchoscope. How to do it by simultaneous occurrence of strictures and the stiff neck. Material: We described 2 cases of patients with received prolonged mechanical ventilation in an intensive care unit. In both patients developed: stiff neck and tracheoesophageal fistula (TEF). The insertion of self-expanding stents has been found successful in both patients. Method: After failed attempts to insert the rigid endoscope, there were temporarily used an oral endotracheal tubes. To put them we used a laryngoscope to visualize the throat, fiberscope9s and guides with stringed tubes. By Hegar9s method (pushing and replacing tubes in increasingly diameter) were obtained extending of tracheal stenosis or narrowing of pharyngeal sphincter. Then through the intubation tube the adjusted stents were inserted into the trachea or esophagus. Correction or control of positioning of stents ended treatments. Conclusions: Stiff neck and narrowing of the trachea or esophagus, are a significant obstacle in the establishment of the stents. They should be taken into account in planning treatment. Use of fiberscope, guides and intubation tubes of increasing diameters is relative simple and cheap way to solve the problem.

Anesthetic Management of a Patient with Noonan Syndrome: A case report
Korean Journal of Anesthesiology, 2006Co-Authors: Min-soo Kim, Jang Eun Cho, Hae Keum KilAbstract:Noonan syndrome is featured by short stature, mental retardation, facial dysmorphia, webbed neck, and heart defects. The phenotype has some similarities with Turner syndrome, but the karyotype is normal and males can be affected. We used Bonfils fiberscope for intubation because we suspected the difficult airway. We report the experience of anesthetic management for osteotomy of calcaneonavicular coalition in a patient with Noonan syndrome.
