Filter by:Failure in airway management is one of the most common anesthesia-related morbidity and mortality. Each individual airway assessment has limitation to predict difficult intubation.
Unanticipated difficult airway comprises of unexpected difficult bag mask ventilation or unforeseen difficult laryngoscopy. The incidence of difficult laryngoscopy or unanticipated difficult intubation in children was varied from 1.2 %to 4.77% depending on general or specific population and type of surgery. The known risk factors of difficult intubation in children were young age, associated syndrome or congenital abnormality and obstructive sleep apnea. Moreover, the predictors of difficult laryngoscopy by physical examination were associated with short interincisors distance, high frontal plane to chin distance, short thyromental distance and Cormack & Lehane classification 3 or 4. However, little knowledge is known regarding difficult bag mask ventilation in children. The incidence of difficult bag mask ventilation was 6.6% according to the single study. A few study reported the independent risk factor of difficult bag mask ventilation in children which were young age, obesity, use of neuromuscular blocking agent and airway surgery. In addition, the association between difficult bag mask ventilation and difficult intubation are still unknown. To understand more of difficult bag mask ventilation in children and factor-association may reduce incidence of morbidity and mortality by identifying difficult airway, preparing personnel and equipment tool in order to improve clinical outcome in pediatric anesthesia. The objectives of the study were to determine the predictors of difficult bag mask ventilation and the association with unexpected difficult intubation in children who came for elective surgery in tertiary care hospital of southern Thailand.
OBJECTIVE: This study aimed to determine the sensitivity and specificity of various anatomic measurements alone or in combination in predicting difficult intubation. The investigators hypothesized that goniomastoid distance, thyrogonial distance and tongue movements are sensitive and specific tests for predicting difficult intubation MATERIALS AND METHODS: The investigators included the data of 170 patients (85 difficult intubation and 85 easy intubation) who underwent an abdominal surgery under general anesthesia. Patients in difficult intubation (n=85) and easy intubation (n=85) groups were matched by age, BMI, and gender. Intubation difficulty scale (IDS) scores were recorded. Upward and downward maximal protrusions of tongue (UMPT and DMPT, respectively) were evaluated in all patients. Anthropometric measurements were measured.
Indirect videolaryngoscopes provide an improved view of the glottis. Unfortunately enhanced video blade angulation leads to difficulty in passage of the endotracheal tube (ETT) towards the larynx around the steep blade angulation despite adequate visualization of the glottis. Pre-shaping the ETT with the rigit malleable stylet is recommended. The investigators hypothesized that using articulating stylet (AS) would enhance first attempt intubation, shorten the intubation time, reduce the possibility of the soft tissue trauma compared to conventional intubation stylet (IS) in patients with difficult airway .
After Local Human Research Ethics Committee approval, emergency medical staff enrolled in this study. After watching a video about the intubation using Airtraq, Glidescope or direct laryngoscopy, they attempted to intubate a pediatric manikin in three different airway models.
The investigators plan to conduct a randomized trial comparing the efficacy of intubating the tracheal using an Aintree intubation catheter through either the LMA-S or I-gel supraglottic devices
In this second phase of the multicenter study the investigators are going to evaluate the use of three different videolaryngoscopes in patients undergoing elective surgery requiring general anesthesia with intubation. The investigators are hypothesizing that these three videolaryngoscopes will succeed for intubation at first attempt in at least 90% of all cases using a difficult airway simulation with extrication collars. As the gold standard, a standard Macintosh blade is being used for comparison. The study consists of 4 arms. Each arm includes 120 patients, sums up to a total of 480 patients.
Difficult intubation is challenging in intensive care units. There are limited data regarding risk factors of difficult intubation in ICU. The primary purpose of the investigators study is to assess the risk factors of difficult airway in adults in ICU.
