Abstract
The escalating airway management demands of cancer patients have prompted us to continually curate airway devices, with supraglottic airway devices (SADs) playing a significant role in this regard. SADs serve as instrumental tools for maintaining an open upper airway. Since the inception of the earliest SADs in the early 1980s, an array of advanced and enhanced second-generation devices have been employed in clinical settings. These upgraded SADs integrate specific features designed to enhance positive-pressure ventilation and mitigate the risk of aspiration. Nowadays, they are extensively used in general anesthesia procedures and play a critical role in difficult airway management, pre-hospital care, and emergency medicine. In certain situations, SADs may be deemed a superior alternative to endotracheal tube (ETT) and can be employed in a broader spectrum of surgical and non-surgical cases. This review provides an overview of the current evidence, a summary of classifications, relevant application scenarios, and areas for improvement in the development or clinical application of future SADs.

Abstract
The perioperative multidisciplinary team approach has probably been best exemplified by the care of awake craniotomy patients. Advancement in anesthesia and meticulous perioperative care has supported the safety and complexity of the surgical and mapping efforts in glioma resection. The discussions in this review will emphasize on anesthetic and perioperative management strategies to prevent complications and minimize their effects if they occur, including current practice guidelines in anesthesia, updates on the applications of anesthetic medications, and emerging devices. Planning the anesthetic and perioperative management is based on understanding the pharmacology of the medications, the goals of different stages of the surgery and mapping, and anticipating potential problems.

Comparative evaluation of Air-Q blocker and Proseal laryngeal mask airway in patients undergoing elective surgery under general anaesthesia: A randomised controlled trial. Indian J Anaesth 2021; 65:S20-S26. [PMID: 33814586 PMCID: PMC7993039 DOI: 10.4103/ija.ija_1254_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 10/19/2020] [Accepted: 12/25/2020] [Indexed: 11/28/2022] Open
Abstract
Background and Aims: The Air-Q blocker (Cook gas LLC, Mercury Medical, Clearwater, FL, USA) is a relatively new supraglottic airway device (SAD) with capability to serve as a conduit for intubation. As there is limited data on Air-Q blocker, the present study was performed to compare the efficacy of Air-Q blocker and Proseal laryngeal mask airway (PLMA) in patients undergoing elective surgery. Methods: A total of 90 American Society of Anesthesiologists (ASA) physical status I and II patients were randomly allocated to Air-Q blocker or PLMA group. Oropharyngeal leak pressure (OLP), insertion success, insertion time, ease of orogastric tube (OGT) insertion, fibreoptic visualisation of the glottis, haemodynamic and ventilation parameters, and complications at emergence and postoperatively were investigated. Results: OLPs were higher in PLMA group as compared to Air-Q blocker group (P = 0.002). Still, the OLP (27.5 ± 5.8 cm H2O) was clinically effective in Air-Q blocker group. The mean time for successful insertion was significantly shorter for Air-Q blocker than PLMA (P = 0.019). The number of attempts to insert both the devices was comparable (P ≥ 0.05). Air-Q blocker provided a significantly better fibreoptic score than PLMA (P = 0.038). The two groups were comparable in terms of ease of OGT insertion, haemodynamics and ventilation parameters, and complications at emergence and postoperatively. Conclusions: Air-Q blocker provides a clinically effective OLP though PLMA provides a slightly better sealing function in patients undergoing laparoscopic and non-laparoscopic surgeries under general anaesthesia requiring neuromuscular blockade. Air-Q blocker has shorter insertion time and a better fibreoptic view of glottis as compared to PLMA.

Abstract
Background and Aims: The problem of difficult and failed intubation led to increased development of equipment for airway management. A number of supraglottic airways have now been developed to facilitate the passage of tracheal tubes. Conventional PVC tracheal tubes are recommended for intubation through the air-Q ILA. No study has compared different PVC tubes for blind intubation through air-Q ILA. Thus, we undertook this prospective, randomised, single blind study to compare two PVC tracheal tubes with different designs viz. conventional PVC tracheal tube (TT) and Parker flex-tip TT with regards to success rate, ease of intubation and total time required for successful intubation through air-Q ILA. Material and Methods: One hundred patients of either sex, aged 18–60 years, belonging to American Society of Anesthesiologists (ASA) physical status class I and II scheduled for elective surgery under general anesthesia requiring endotracheal intubation were included in the study. Blind intubation using conventional PVC TT and Parker flex-tip tube was done in group A (n = 50) and group B (n = 50), respectively. Results: The first attempt success rate in Parker flex-tip TT was significantly more as compared to conventional PVC TT (P = 0.002). Success rate of intubation was significantly more in Parker flex-tip TT as compared to conventional PVC TT (P = 0.004). The intubation was significantly easy in Parker flex-tip tube as compared to conventional PVC TT (P = 0.002). Total time of intubation was less in Parker flex-tip tube as compared to PVC TT (P = 0.043). Conclusion: Unique design of the Parker Flex-tip TT resulted in increase in success rate, first attempt success rate and ease of intubation in group B in present study.

Abstract
Background Air-QⓇ laryngeal mask airway (LMA) is a second-generation supraglottic airway device (SAD) providing adequate airway control despite the unfavorable airway anatomy in children. Several studies have assessed it as a conduit for tracheal intubation and compared its efficacy with that of other SADs, but there are no studies comparing the laryngeal view with midline and rotational insertion techniques of Air-Q. Therefore, this study compared the fiber-optic bronchoscopic (FOB) assessment of the Air-Q position using these two insertion techniques. Methods This randomized controlled trial included 80 patients of the American Society of Anesthesiologists physical status I/II of either sex (age group 5–12 years, weight 10–30 kg), who were scheduled for elective surgery in the supine position under general anesthesia. The patients were randomly subjected to rotational and midline technique groups (n = 40, each), and appropriate sized Air-Q, based on the weight of the patient, was inserted using the technique allocated to each patient. Time taken and number of attempts for successful insertion of the devices and any complications after removal of device were studied. Results FOB grade 1 (ideal position) was seen in 29/40 (72.5%) and 19/40 (47.5%) children subjected to the rotational and classic midline techniques, respectively (P = 0.045). The time taken to successfully insert the Air-Q was significantly lesser in the rotational technique group (7.2 ± 1.5 s) than in the classic midline technique group (10.2 ± 2.1 s) (P < 0.001), whereas complications were similar in both groups. Conclusions The rotational technique was associated with better FOB view, and was faster than the classic midline technique of Air-Q insertion in pediatric patients.

Abstract
Background When managing patients with a difficult airway, supraglottic airways (SGAs) have been used as rescue devices or to serve as a conduit for endotracheal intubation. The current study compares various clinical outcomes, including the bronchoscopic view of the glottis when using 2 SGAs, the Air-Q® laryngeal mask airway (LMA) and the i-gel® SGA, in pediatric patients. Methods Patients ≤18 years of age were prospectively randomized to receive either the Air-Q® LMA or the i-gel® SGA. Following SGA placement, a flexible fiberoptic bronchoscope was inserted through the SGA to visualize the glottis. Time taken to obtain the bronchoscopic view and place the SGA, and the ability to seal the airway at 20 cmH2O were compared. The bronchoscopic view obtained was graded as follows: 1) glottic aperture seen completely; 2) glottic aperture seen partially with visual obstruction <50%; 3) glottic aperture seen, but visual obstruction >50%; and 4) glottic aperture not seen. Results Fifty patients were enrolled and 48 (22/26 male/female) were included in the analysis. Median age was 13 years (IQR: 7, 16) and median weight was 49 kg (IQR: 25, 70). The Air-Q® LMA and i-gel® SGA groups did not differ in device placement time (median of 19 vs 21 seconds; 95% CI of difference in medians: - 2 to 7; P=0.331), the time to achieve fiberoptic view of the glottis (median of 25 vs 21 seconds; 95% CI of difference: - 9 to 8; P=0.489) or the grade of the bronchoscopic view of the airway. Eight Air-Q® and 6 i-gel® supraglottic devices sealed the airway at 20 cmH2O. Discussion The time required for successful placement of the SGA, the time required for bronchoscopic view, and the quality of bronchoscopic view through the Air-Q® LMA and the i-gel® SGA did not differ.

Abstract
Background Rapid placement of a reliable airway is the most important task in anesthesia practice. Airway management is a critical skill to provide safe anesthesia since morbidity. In addition, mortality due to anesthesia could be linked to difficulty or failure in airway management. In this study, intubation success was compared between two methods, AirQ-ILA and LMAfastrach, among candidates for elective surgery under general anesthesia. Methods In this clinical trial, patients, who were candidates for elective surgery under general anesthesia at Firoozgar and Rasoul Akram Hospitals, were randomly divided into LMAfastrach and AirQ-ILA groups. Heart rate before and after induction and intubation, diastolic blood pressure, systolic blood pressure, duration of device insertion, intubation time, number of attempts until successful device insertion and trachea intubation, and success or failure in the insertion of the device and the tube were recorded; as for statistical analysis, SPSS version 21 was considered. Results In comparison with the LMAfastrach group, the device insertion time and intubation time were significantly longer in the AirQ-ILA group (P < 0.05). However, the groups showed no significant difference regarding the number of device and tube insertion attempts (P > 0.05). Moreover, no significant difference was observed in the success of device insertion and intubation in either LMAfastrach or AirQ-ILA group (P > 0.05). Conclusions The LMAfastrach and AirQ-ILA methods were not significantly different regarding the success of airway instrument application and intubation, while the device insertion time and intubation time were significantly longer in the AirQ-ILA group in comparison with the LMAfastrach group.

Abstract
Abstract
Background
Supraglottic airway devices commonly are used for securing the airway during general anesthesia. Occasionally, intubation with an endotracheal tube through a supraglottic airway is indicated. Reported success rates for blind intubation range from 15 to 97%. The authors thus investigated as their primary outcome the fraction of patients who could be intubated blindly with an Air-Qsp supraglottic airway device (Mercury Medical, USA). Second, the authors investigated the influence of muscle relaxation on air leakage pressure, predictors for failed blind intubation, and associated complications of using the supraglottic airway device.
Methods
The authors enrolled 1,000 adults having elective surgery with endotracheal intubation. After routine induction of general anesthesia, a supraglottic airway device was inserted and patients were ventilated intermittently. Air leak pressure was measured before and after full muscle relaxation. Up to two blind intubation attempts were performed.
Results
The supraglottic airway provided adequate ventilation and oxygenation in 99% of cases. Blind intubation succeeded in 78% of all patients (95% CI, 75 to 81%). However, the success rate was inconsistent among the three centers (P < 0.001): 80% (95% CI, 75 to 85%) at the Institute of Anesthesia and Pain Therapy, Kantonsspital Winterthur, Winterthur, Switzerland; 41% (95% CI, 29 to 53%) at the Department of Anesthesiology and Intensive Therapy, Medical University of Lodz, Lodz, Poland; and 84% (95% CI, 80 to 88%) at the Institute of Anesthesiology, University Hospital Zurich, Zurich, Switzerland. Leak pressure before relaxation correlated reasonably well with air leak pressure after relaxation.
Conclusions
The supraglottic airway device reliably provided a good airway and allowed blind intubation in nearly 80% of patients. It is thus a reasonable initial approach to airway control. Muscle relaxation can be used safely when unparalyzed leak pressure is adequate.

Abstract
BACKGROUND AND AIMS Ambu® AuraGain™ (AG) (Ambu, Ballerup, Denmark) is a supraglottic device which has a design facilitating its use as a conduit for intubation. We designed this prospective observational study to assess the ease of AG placement in paralysed patients, determine its position and alignment to the glottis and assess its utility as a conduit for intubation. METHODS One hundred patients, aged 18-60 years, American Society of Anesthesiologists physical status I-II, undergoing elective surgery under general anaesthesia were included in the study. The ease and number of attempts for successful insertion, ease of gastric tube insertion, leak pressures, fibre-optic grade of view, number of attempts and time for tracheal intubation, time for AG removal and complications were recorded. The mean, standard deviation (SD), interquartile range (IQR) and range were calculated. The upper limit of confidence interval for overall failure rate was calculated using Wilson's score method. RESULTS AG was successfully inserted in all patients. The mean (SD) time taken for insertion was 17.32 (8.48) s. The median [IQR] leak pressures were 24 [20-28] cm of H2O. Optimal laryngeal view for intubation was obtained in 68 patients. Eighty-eight patients could be intubated in the first attempt. Five patients could not be intubated. The overall failure rate of device was 9%. CONCLUSION AMBU® AuraGain™ serves as an effective ventilating aid, but caution is suggested before using it as a conduit for endotracheal intubation.
