Comparison between lignocaine nebulization and airway nerve block for awake fiberoptic
bronchoscopy-guided nasotracheal intubation: a single-blind randomized prospective study

Introduction: Fibreoptic Intubation (FOI) is the gold standard for managing difcult airways. There are various approaches such as: Nebulization with lidocaine; 'Spray as you go'(SAYGO); Airway nerve block - blocking superior laryngeal nerve & recurrent laryngeal nerve & sedation. The present study aims to compare 'airway nerve block' (NB) and 'spray as you go'(SA) method for awake exible bronchoscopic intubation used in combination with conscious sedation. Methods: 60 patients of age group 18 – 65 years with difcult airway undergoing general anaesthesia with nasotracheal intubation, were randomly allocated into two groups. After premedication & nasal preparation, all patients received injection dexmedetomidine at a dose of 1µg/kg in 100ml of 0.9% NS over 10 minutes. In Group SA, 2ml lignocaine 4% was sprayed above and below the cords after visibility of glottic opening via working channel of the bronchoscope and 2 ml lignocaine 4% within trachea before insertion of endotracheal tube. In Group NB, bilateral superior laryngeal nerves & recurrent laryngeal nerve was blocked. Then a exible breoptic bronchoscope preloaded with a exometallic endotracheal tube of appropriate size was then inserted via nasal route. Results: The mean intubation time for Group NB [87.27 ± 7.58 sec] was shorter than that for Group SA [190.33 ± 9.14] (p<0.0001). Conclusion: Awake exible bronchoscopic intubation under sedation with airway nerve block provides better intubating conditions compared to SAYGO

Abstract Background There are doubts among anesthesiologists on the use of the Laryngeal Mask Airway (LMA) in nasal surgeries because of concerns about the occurrence of blood leakages to the airway. We hypothesized that the use of LMA-Supreme (LMA-S) in nasal surgery is comparable with endotracheal tube (ETT) according to airway protection against blood leakage through the fiberoptic bronchoscopy, oropharyngeal leakage pressure (OLP), heart rate (HR), mean arterial pressure (MAP), and postoperative adverse events. Methods The present study was conducted in a prospective, randomized, single-blind, controlled manner on 80 patients, who underwent septoplasty procedures under general anesthesia, after dividing them randomly into two groups according to the device used (LMA-S or ETT). The presence of blood in the airway (glottis/trachea, distal trachea) was analyzed with the fiberoptic bronchoscope and a four-point scale. Both groups were evaluated for OLP; HR; MAP; postoperative sore throat, nausea, and vomiting; dysphagia; and dysphonia. Results In the fiberoptic evaluation of the airway postoperatively, less blood leakage was detected in both anatomic areas in the LMA-S group than in the ETT group (glottis/trachea, p = 0.004; distal trachea, p = 0.034). Sore throat was detected less frequently in the LMA-S group at a significant level in the 2nd, 6th, and 12th hours of postoperative period; however, other adverse events were similar in both groups. Hemodynamic parameters were not different between the two groups. Conclusion The present findings demonstrate that the LMA-S provided more effective airway protection than the ETT in preventing blood leakage in the septoplasty procedures. We believe that the LMA-S can be used safely and as an alternative to the ETT in septoplasty cases. Trial registration This trial is registered at the US National Institutes of Health (ClinicalTrials.gov) # NCT03903679 on April 5, 2019.

Introduction: Local Anaesthesia (LA) is the mainstay of any routine dental extraction. Accomplishing optimum anaesthesia with least pain and anxiety to patients is a challenge. Hence, modification of technique and application of routine dental LA to enhance patient comfort is the need of the hour. In this pursuit, a prospective cohort study was carried out to evaluate the effectiveness of greater palatine nerve block as an alternative to nasopalatine nerve block in anaesthetising the anterior palatal mucosa and to achieve optimum palatal anaesthesia. Aim: The primary outcome variable is to assess the extent of the anaesthetic effect of greater palatine nerve block in maxillary anterior palatal region. Materials and Methods: A total of 100 patients scheduled for the extraction of ipsilateral anterior and posterior maxillary teeth were included in this prospective study between June 2017 to June 2019. Palatal anaesthesia for all the extractions done was achieved only with greater palatine nerve block. After an interval of five minutes, the extent of palatal anaesthesia from the posterior palatal tissue to the anterior region was evaluated for both subjective and objective symptoms. Pain on the palatal mucosa was assessed using Numerical rating scale of 0-10. Post-evaluation, depending on the proposed tooth of extraction, buccal anaesthesia was achieved with Posterior superior alveolar nerve block for posterior teeth and infraorbital nerve block for anterior teeth. Results: Of the 100 patients administered with greater palatine nerve block, it was observed that in 36 patients (36%) had effectiveness in anaesthesia till central incisor, 28 (28%) patients had effectiveness in anaesthesia till lateral incisor, 20 (20%) patients had effective in anaesthesia till the canine and 16 (16%) patients anaesthetic effects were limited to posterior teeth. Overall, 84% had varied degree of positive anterior anaesthesia with greater palatine nerve block alone. Conclusion: Greater palatine nerve block was effective in providing anaesthesia to the posterior region till the premolars, with the extended complete anaesthesia in the anterior region with similar action as the nasopalatine nerve block administered to anaesthetise the anterior palate for extraction of the anterior teeth.
