Background: Deep neck space infection is challenging to anesthesiologist for coping with upper airway obstruction and difficult intubation.
Objective: To explore anesthetic techniques and results of airway management in patients with deep neck space infection who underwent surgical drainage and determine the factors related to intubation difficulty.
Material and method: A retrospective analytical study was conducted on surgical patients with deep neck space infection who received general anesthesia in Lampang Hospital during June 2009-August 2014. Clinical and anesthetic data were analyzed by using descriptive statistics. Factors associated with difficult or failed intubation, retained intubation and length of stay were analyzed with Fisher’s exact probability test and one-way ANOVA.
Results: Among 73 patients in the study, 69.9% were male and the mean age was 53.4±14.3 years (range 20-82). Most of infection sites were suprahyoid neck space (56.2 %) and Ludwig’s angina (20.6%). The most common techniques for airway management were direct laryngoscopy (67.1%) and fiberoptic intubation (23.3%). Three patients underwent tracheostomy. Retained intubation was found in 46 cases and most of them (26 cases) were extubated in the first postoperative day. The mean length of stay was 9.5 ± 4.8 day (range 1-33) without significant difference between tracheostomy and endotracheal intubation groups. ASA physical status class 3-4, limited mouth opening and difficult intubation were risks factors for retained intubation. No statistically significant factors were associated with difficult or failed intubation by direct laryngoscopy.
Conclusion: Intravenous induction and intubation by direct laryngoscopy with succinylcholine was the most common anesthetic and airway management technique used this study. There were no statistically significant factors associated with difficult or failed intubation by this technique.
