Objective: To highlight the problems and solutions in airways management in patients with tracheal stenosis undergoing surgical interventions and to highlight the alternative methods of airway control where high frequency ventilatory facility is not available. Study Design: Case series study. Place and Duration: Combined Military Hospital Rawalpindi from 1st Jan 2004 to 30th June 2007. Patients and Methods: Twenty nine patients of both sex and all age groups presenting with difficulty in breathing due to tracheal stenosis undergoing surgical intervention on trachea have been included. All the patients were managed under general anaesthesia. Nasogastric tube 10 Fr, suction catheter, laryngeal mask airway or mask ventilation was used for initial ventilation where conventional endotracheal tube of even smallest size did not work. Results: Small size endotracheal tube were used in twenty four patients. Difficulty was faced in five patients. In these patients endotracheal tube of smallest size available could not be passed and we had to provide ventilation by innovative measures like nasogastric tube 10Fr in one, suction catheter 10Fr in two, laryngeal mask airway in one and mask ventilation in one. There was no mortality. Conclusions: Adequate ventilation during tracheal stenosis surgery can be very difficult in some cases. Therefore a thorough understanding, a tier of flexible plans and a variety of ventilating means should be arranged before administering anaesthesia.Nasogastric tube 10Fr or suction catheter of similar size are suitable alternative if facility for high frequency ventilation is not available.

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: Despite several advantages over endotracheal tube (ETT), laryngeal mask airway (LMA), which is used in emergencies under difficult airway maintenance conditions, is rarely utilized in prolonged surgery. We compared the variables representing intraoperative gas exchange with second-generation LMA and ETT during prolonged laparoscopic abdominal surgery. Methods: Prolonged surgery was defined as a surgery lasting more than 2 h. In total, 394 patients who underwent laparoscopic liver resection via either second-generation LMA or ETT were retrospectively analysed. Parameters including end-tidal pressure of carbon dioxide (ETCO2), tidal volume (TV), respiratory rate (RR), peak inspiratory pressure (PIP), arterial partial pressure of carbon dioxide (PaCO2), pH, and ratio of arterial partial pressure of oxygen to fractional inspired oxygen (PFR) during surgery were compared between the two groups. In addition, the incidence of postoperative pulmonary complications (PPC) including pulmonary aspiration was also compared. Results: The values of ETCO2, TV, RR and PIP during pneumoperitoneum were comparable between the two groups. Although PaCO2 at 2 h after induction was higher in patients with LMA (40.5 vs. 38.5 mmHg, p < 0.001), the pH and PFR values of the two groups were comparable. The incidence of PPC was not different. Conclusion: During prolonged laparoscopic abdominal surgery, the second-generation LMA facilitates adequate intraoperative gas exchange and represents an alternative to ETT.
