Introduction: In an unanticipated difficult airway or in an emergency situation of cannot-intubate-cannot-ventilate scenario, Supraglottic Airway Devices (SGD) are recommended as rescue devices for establishing airway quickly to prevent hypoxia. Aim: To compare efficacy of i-gel airway and Laryngeal Mask Airway supreme (LMA supreme) as ventilatory devices and the time taken for their insertion in anaesthetised and paralysed patients with simulated difficult airway. Materials and Methods: One hundred and eighty adult patients with simulated difficult airway were randomly allocated to two groups of 90 patients each. In group I: i-gel and in group S: LMA supreme was inserted. Primary outcome studied was time taken for insertion of SGD. Secondary outcomes were the number of attempts taken for insertion of device, oropharyngeal leak pressure, ease of gastric catheter insertion, fibreoptic bronchoscopic view of anatomical alignment of device with glottic opening. Quantitative variables were compared using unpaired t-test/Mann-Whitney Test, between the two groups. Qualitative variable were compared using Chi-Square test/Fisher’s-exact test. Results: Total time taken for successful insertion was significantly shorter with group i-gel as compared to group LMA supreme {median (IQR) {19 (18.25-21)} versus {24 (23-24)} with p-value ≤0.0001. Overall success rate of insertion (96.67% vs 97.78%, p=1.000) and oropharyngeal leak pressure (p-value=0.555) of i-gel and LMA-S were comparable. i-gel has better anatomic alignment with glottic opening as compared to LMA-S (p-value ≤0.0001). Gastric tube insertion was easy in all patients in both the groups. Conclusion: Shorter time for the insertion of i-gel was observed due to absence of inflatable cuff, although both LMA-S and i-gel are equally efficacious as ventilatory devices in patients with simulated difficult airway under general anaesthesia with controlled ventilation.

The objective: to assess and compare supraglottic airways of LMA-Supreme and i-gel during orbital osteosynthesis.Subjects and methods. 91 patients were included into the study. All of them underwent osteosynthesis of the orbit. The patients were randomly divided into two groups. LMA-Supreme group included 42 patients, while i-gel group included 49 patients.Results. The parameters of hemodynamics, gas exchange, and artificial pulmonary ventilation (APV) did not basically differ between the groups at different stages of the study. The oropharyngeal leak pressure differed between the groups at the end of surgery and made (Me – median, Q1 and Q3 – upper and lower quartiles): 28.0 (22.0; 30.0) and 21.0 (19.0; 27.0) mm WG the LMA-Supreme and i-gel groups, respectively; p = 0.021. A significant difference was observed in the insertion time of supraglottic airways (Me is the median, Q1 and Q3 are the upper and lower quartiles): 27.5 (19.3; 36.5) sec. for LMA-Supreme and 15.0 (13.8; 25.0) sec. – for i-gel; p = 0.001. When inserting the LMA-Supreme duct in 33 (78.6%) patients, jaw thrust maneuver, extension of the neck, etc. were required; while in the i-gel group, similar maneuvers were necessary in 18 (36.7%) patients; p < 0.001. The number of postoperative complications was minimal in both groups.Conclusion. Both supraglottic airways can be used with equal efficacy in osteosynthesis of the orbit. At the same time, the i-gel duct has an advantage over the LMA-Supreme in speed and simplicity of insertion. The LMA-Supreme had greater leak pressure at the end of surgery, which might be an advantage in patients requiring greater peak inspiratory pressure to provide effective APV.

Lma Supreme

Background In March 2007, a new disposable laryngeal mask airway (LMA) became available. The LMA Supreme (The Laryngeal Mask Company Limited, St. Helier, Jersey, Channel Islands) aims to combine the LMA Fastrach feature of easy insertion with the gastric access and high oropharyngeal leak pressures of the LMA ProSeal. Methods The authors performed an evaluative study with the LMA Supreme, size 4, on 100 women to measure the ease of insertion, determinate the laryngeal fit by fiberoptic classification, evaluate the oropharyngeal leak pressure, and report adverse events. Results Insertion of the LMA Supreme was possible in 94 patients (94%) during the first attempt, and in 5 patients (5%) during the second attempt. In one small patient, the LMA Supreme could not be inserted because of limited pharyngeal space. This patient was excluded from further analysis. Insertion of a gastric tube was possible in all patients at the first attempt. The median time for LMA Supreme insertion was 10.0 s (+/-4.7 s; range, 8-30 s). Laryngeal fit, evaluated by fiberscopic view, was rated as optimal in all patients, both immediately after insertion of the LMA Supreme and at the end of surgery. After equalization to room pressure, the mean cuff volume needed to achieve 60 cm H2O cuff pressure was 18.4 ml (+/-3.8 ml; range, 8-31 ml). The mean oropharyngeal leak pressure at the level of 60 cm H2O cuff pressure was 28.1 cm H2O (+/-3.8 cm H2O, range, 21-35 cm H2O). Eight patients (8.1%) complained of a mild sore throat. No patient reported dysphagia or dysphonia. Conclusions Clinical evaluation of the LMA Supreme showed easy insertion, optimal laryngeal fit, and low airway morbidity. Oropharyngeal leak pressure results were comparable to earlier data from the LMA ProSeal.

Background: Intubating oral airways are widely used during fibreoptic orotracheal intubationin order to improve the bronchoscopic visualisation of the glottis and facilitate the procedure. This study compares the visualisation of the glottic opening with bronchoscope using Berman or Ovassapian intubating airway.Methods: We conducted a randomised comparative prospective study one hundred twenty patients with no clinical indicators of the difficult airway. The two oral intubating Berman and Ovassapian airways were compared during fibreoptic endotracheal intubation in anaesthetized patients. The bronchoscopic view, bronchoscopic time, and the total time for intubation were compared.Result: The bronchoscopic view was significantly better with Berman intubating airway (unobstructed view 74%) as compared to the Ovassapian airway (unobstructed 38.4%) (p-value 0.002). The Berman airway provided a significantly shorter duration for visualisation of the vocal cord and intubation of trachea in comparison to the Ovassapian airway.Conclusion: Berman airway provided a better bronchoscopic view as well as shorter bronchoscopic and intubation time as compared to the Ovassapian airway.

Background About 50% of the elderly undergoing emergency abdominal surgery are malnourished. The role of timely surgical nutritional access in this group of patients is unknown. Methods We analyzed the National Inpatient Sample database from 2009 through the first three-quarters of 2015 of patients aged ≥65 years who were malnourished and underwent major abdominal surgery for the acute abdomen within the first 2 days of hospital admission. Results Of 3 246 721 patients analyzed, 4311 patients met inclusion criteria. Of these, only 507 (11.8%) patients had surgical nutritional access (gastrostomy or jejunostomy) (group I), while 3804 patients (88.2%) did not (group II). In the propensity score-matched population, there were 482 patients in each group. The patients in group I had lower odds of mortality and postoperative gastrointestinal complications (paralytic ileus, anastomotic dehiscence, and intestinal fistulae) ( P-value <.01, respectively). Discussion Elderly who receive surgical nutritional access have lower rates of gastrointestinal complications and mortality.

Abstract Introduction Wide awake local anaesthesia no tourniquet (WALANT) is a widely used technique in upper limb procedures that has gained increasing popularity during the coronavirus pandemic. The benefit of WALANT for foot and ankle surgeries is less clear, especially in patients with multiple comorbities. The primary aim of this study was to compare post-operative pain levels in patients undergoing ankle fracture fixation. Secondary objectives included comparison of intra-operative patient experiences, clinical outcomes, and patient satisfaction 1-year post-procedure. Method 129 patients presenting with ankle fractures were enrolled in a multicenter randomised control trial from February 2016 to January 2020. Patients with medial malleolar, lateral malleolar, bimalleolar or trimalleolar fractures received either WALANT (62 patients) or spinal anaesthesia (67 patients). A 5ml solution of 0.9% saline and 2% lidocaine with 1: 100,000 adrenaline was used for WALANT. Results Compared to patients who received spinal anaesthesia, those in the WALANT group experienced less post-operative discomfort and were more satisfied 1-year post-procedure (p-value = 0.003). Surgical outcomes were similar for both groups. Cost analysis revealed that WALANT is significantly more economical. Conclusions WALANT is an effective and safe anaesthetic for foot and ankle procedures. Without use of a tourniquet, it reduces post-operative pain and so, eases patient recovery.

Objectives: To compare the complications and outcomes of lateral entry pin fixation with medial and lateral pin fixation for Gartland type III supracondylar fractures of humerus. Methodology: This prospective comparative study involving 190 patients of Gartland type III close supracondylar fractures were included. from March-2019 to Dec-2020. In all patients, initially the elbow was mobilized using the splint placed above the elbow joint at 30 to 45 degrees’ flexion. After closed reduction, lateral pinning was applied in group I and in group II lateral and medial cross pinning was applied using the standard protocol. Patients were followed for iatrogenic ulnar nerve injury, radiologic and function outcomes in-terms of loss of reduction, elbow range of motion, loss in carrying angle and functional outcomes. Results: The two groups were comparable for loss of elbow range of motion, loss of carrying angle and loss of Bauman's angle. On clinical examination, immediate post-operative ulnar nerve injury was diagnosed in 4 (4.2%) cases in group II and in no patient in group I (p-value 0.12). Satisfactory functional outcomes were achieved in 85 (89.5%) patients in group I and in 88 (92.6%) patients in group II (p-value 0.44). Conclusion: Lateral pinning provided stable fixation clinically and radiologically as compared to lateral and medial cross pinning.
