Awake Fiberoptic Intubation

Awake Fibreoptic Intubation (AFOI) is, nowadays, the gold standard in predicted difficult airway management. Numerous practice guidelines have been developed to assist clinicians facing with a difficult airway. If conducted without sedation, it is common that this procedure may lead to high patient discomfort and severe hemodynamic responses. Sedation is frequently used to make the process more tolerable to patients even if it is not always easy to strike a balance between patient comfort, safety, co-operation, and good intubating conditions. In the last years, many drugs and drug combinations have been described. This minireview aims to discuss the evidence supporting the use of Dexmedetomidine (DEX) in the AFOI management.

Awake Fiberoptic Intubation

Background- Awake fiberoptic intubation is the recommended technique for anticipated difficult airway management which requires effective local anesthesia for patient's comfort and co-operation. In this study, we compared airway nerve blocks and “Spray as you go” technique for awake fiberoptic intubation in difficult airway patients. Method- Sixty adult patients with an anticipated difficult airway with Mallampati Class III and IV were selected and randomized into two groups for awake fiberoptic intubation. Each group receiving lignocaine as a local anesthetic with either of two different methods. Group A (n=30) via airway nerve blocks using transtracheal and superior laryngeal nerve block; and group B (n=30) via intubating fiberscope using ‘spray as you go’ technique. We compared two groups using the Number of attempts for intubation, Intubation time, Intubating conditions, Cough count, Hemodynamic response, Severity scale [patients comfort], and the additional required dose of lignocaine used. Descriptive statistics were done for all data. p-value<0.05 was considered statistically significant. The result- we found that airway nerve blocks provide better local anesthesia by providing good intubating conditions with less cough count, less intubation time, and better hemodynamic stability as compare to spray as you go group. None of the patients showed any evidence of lignocaine toxicity. But an additional dose of lignocaine used was significantly more number of patients in the spray as you go, group. However patient comfort and acceptance is equal in both groups as patient severity score was the same in both groups and all patients got successfully intubated in both the groups Conclusion- airway nerve block technique of local anesthesia is better than spray as you go method however spray as you go technique can be used in cases where airway blocks are not possible.

Awake Fiberoptic Intubation

Background- Awake nasal or oral flexible fiberoptic intubation (AFOI) is technique of choice in known or anticipated difficult airway . The main aim was to have calm and cooperative patient who can follow verbal commands while maintaining adequate oxygenation . In our study, we compared the analgesic and sedative effects of fentanyl and midazolam with nalbuphine and midazolam in patients undergoing awake fiberoptic intubationmore tolerable and comfortable for the patient but also to ensure optimal intubating conditions. Material and Methods– A prospective, randomized comparison study among patients between the age of 18 and 60yrs of either sex, with anticipated difficult airway . We compared the analgesic and sedative effects of fentanyl and midazolam with nalbuphine and midazolam in patients undergoing awake fiberoptic intubation. The primary objectives of our study were to observe the level of sedation, intubation score and OAS score after completion of procedure. The secondary objectives included assessment of patient comfort, intubation time, hemodynamic changes and complications. Results – We found that comfort score and intubation time were significant lesser in Group which received fentanyl and midazolam than Group which received nalbuphine and midazolam . (p<0.05). The intubation attempt was similar in both groups (P>0.05). Conclusion– we concluded that both regimens used in this study provided comparable intubating conditions, better sedation and analgesia was observed in group fentanyl for airway procedure events. Our study concluded fentanyl to be the drug of choice for blunting of pressor response in such patients.

Awake Fiberoptic Intubation

Achondroplasia is a common form of dwarfism and possesses multiple anesthetic challenges including securing of intravenous line, monitoring and calculating drug dosage, spine abnormality, difficulty in mask ventilation and endotracheal intubation, obesity, cardiopulmonary and neurological system abnormality. There is multiple systems involvement, therefore thorough preanesthetic check ups, investigations and planning for anesthesia is important. Here we came across 36 years old female patient, achondroplasic dwarf (height- 100cm) with thoracolumbar kyphoscoliosis, fused cervical spine, short neck and restricted neck movement with mild pulmonary restrictive disease for total abdominal hysterectomy. Patient also had complained of generalized weakness and fatigue. She had a limited neck extension and short neck possesses anticipated difficult intubation, therefore we planned awake fiberoptic intubation with smaller size endotracheal tube for airway management and general anesthesia in a patient with difficult airway and spine for total abdominal hysterectomy. As the spread of the drug in regional anesthesia is unpredicted, we planned general anesthesia with awake fiberoptic intubation to avoid the risk of neurological injury while extending the neck during laryngoscopy for tracheal intubation due to restricted neck movement.

La intubación del paciente despierto con fibrobroncoscopio es la técnica más ampliamente utilizada ante la presencia de una vía aérea difícil conocida. Sin embargo, hay varias razones que limitan su ejecución. La mayoría de los anestesiólogos están de acuerdo en que el fibrobroncoscopio constituye un reto en cuanto a su aprendizaje. Además, una vez aprendida esta habilidad, requiere una práctica regular para su mantenimiento. La hiperreactividad de la vía aérea por una anestesia tópica inadecuada, el exceso de sedación y agitación, la hemorragia nasal, y en algunos casos, la progresión de una obstrucción parcial existente la vía aérea hasta una total, han sido comunicados como riesgos de la técnica. Los videolaringoscopios pueden ser una solución ante una vía aérea difícil prevista. Su uso se está extendiendo ampliamente porque son dispositivos fáciles de manejar, económicos y versátiles, permitiendo su utilización en un mayor número y variedad de pacientes. ABSTRACT Are videolaryngoscopy  an alternative option to fibreoptic bronchoscopy in awake patient intubation? Awake fiberoptic intubation is the most widely used approach in the management of the known difficult airway. However, there are several problems that limit this technique. Most anesthesiologists agree on the challenging nature of fiberoptic intubation training. The maintenance of this skill requires regular practice. Among the known risks of this technique are airway hiperreactivity due to inadequate topic anesthesia, excessive sedation or agitation, nasal hemorrhage and, in some cases, progression from partial to complete airway obstruction. Vídeolaryngoscopy can be an alternate option in the management of known difficult airway. These devices are becoming widely used because they are easy to use, inexpensive and versatile, and thus they can be used in a wider variety and number of patients.

Awake Fiberoptic Intubation

Abstract Background: Securing the airway is a core skill for an anesthesiologist, the gold standard of which is tracheal intubation. Patient with subglottic tumor is a situation of difficult airways and could be a challenge for anesthesiologists. The “cannot ventilate, cannot intubate” during anesthesia induction can be lethal. So we always prepared awake approach for diagnosed difficult airway, but awake fiberoptic intubation may be also failed. Case presentation: In this case report we present a 55 years old female patient was scheduled for laryngeal tumor resection, and was planned awake intubation guided by fiber bronchoscope. After awake intubation attempt failed, emergency tracheostomy was successfully completed by ENT surgeon. After securing airway, general anesthesia was performed and the operation proceeded with laryngeal tumor resection. Conclusions: It is important that ENT surgeon must be asked to remain standby for possible need of emergency tracheostomy to prevent awake fiberoptic intubation failure. Ultrasound or computed tomography scan examination of the trachea may be useful to provide guidance for anesthesiologists to choose the appropriate endotracheal tube IDs or tracheostomy directly by measuringthe degree of airway stenosis.

The Impact

The purpose of this study was to examine the impact of surgical pathology, anesthesiologist experience, and airway technique on surgically relevant outcomes in patients identified by preoperative laryngoscopy to have a difficult airway due to head and neck pathology. We prospectively recorded a series of 152 difficult airway cases due to head and neck pathology out of 2,145 direct laryngoscopies undertaken between November 2005 and June 2008. One of two senior anesthesiologists specializing in head and neck procedures intubated 101 (66.4%) of the 152 patients and did so 3.3 minutes faster (p = 0.51), with better oxygenation (87.3 vs. 81.8%; p = 0.02) and fewer airway plan changes (p = 0.001) than did other, nonspecialist anesthesiologists. Predictors of failure of the first intubation plan included: cancer diagnosis (p = 0.02), previous radiotherapy (p = 0.03), and supraglottic lesions (p = 0.03). Glottic/subglottic lesions required the most intubation attempts (p = 0.02). Awake fiberoptic Intubation was the most common method used (44.7%) but resulted in a change in the airway plan in 6 cases (8.8%). Gas induction maintained the best oxygenation (p = 0.01). Awake tracheostomy was infrequent (1.3%) and took the longest (p = 0.006). We concluded that difficult airways due to head and neck pathology require teamwork and a backup plan. An anesthesiologist specializing in head and neck procedures may help to avoid adverse outcomes associated with cancer, especially previously irradiated supraglottic/glottic lesions, leading to a less frequent need for awake tracheostomy.
