Methods: 216 patients, ASA class I~II, aged 5.2~63 years, and scheduled for elective plastic surgery, were included. The reasons of the difficult intubation are the limitation of neck extension(n=105), the limitations of combined neck extension and mouth opening(n=82), microstomia deformity due face scar(n=19), ankylosis of temporomandibular joint(n=4)and micromaxillary deformity(n=6). By the Comack's classification, all the patients had the laryngeal exposure of III grade or more. The tracheal intubation was done under neuroleptanalgesia combined with topical anesthesia in 67 patients, intravenous anesthesia of sedative drugs and nondepolarizing relaxants of subnormal doses in 42 subjects, and total intravenous or inhaled anesthesia in 107 cases, respectively. Results: The incidence of successful intubation was 100%. The intubation time was 1~65min, with a mean time of 4.7min. Of all the patients, the duration of intubation manipulation was less 3min in 76 patients(35.2%), 3~10min in 81 patients(37.5%), and more than 10min in 59 patients(27.3%), respectively. Anesthetic techniques could affect significantly the intubation time and the incidences of complications. Conclusions: The skilled technique and adequente anesthetic effect are key factors to assure successful manipulation of intubation by fiberoptic rigid style laryngoscope.

难气管插管的原因 主要为面、颏、颈、胸瘢痕粘连和挛缩所致的头后仰活动严重受限(105例,图1)以及头后仰活动受限复合张口活动受限(82例,图2); 另外还有面部瘢痕挛缩所致的小口畸形(19例,图3); 颞颌关节强直4例和小颌畸形者6例(图4)。其中喉头显露Ⅲ级的有51例; 喉头显露Ⅳ级或直接喉镜无法置入者有165例。 |
