A systematic review and meta-analysis on the efficacy and safety of the Baska mask versus other laryngeal mask airways during general anaesthesia.

BACKGROUND: The Baska mask is a supraglottic airway device used during general anaesthesia that combines features from various other devices. This systematic review aims to compare its efficacy and safety with other laryngeal mask airways. METHODS: Randomised controlled trials were identified by searching PubMed, Scopus, Web of Science and Cochrane Library. RevMan software was used for meta-analysis, with mean difference and risk ratios calculated for continuous and dichotomous data, respectively, along with a 95% confidence interval. RESULTS: The meta-analysis found that the Baska mask provides a better oropharyngeal seal pressure (mean difference = 7.03; 95% confidence interval = [6.00, 8.07], p < 0.00001) and a higher rate of maximal seal pressure (risk ratio = 18.38; 95% confidence interval = [2.53, 133.47], p = 0.004) compared to other laryngeal mask airways. However, the Baska mask had lower success rates in first-attempt insertion (risk ratio = 0.79; 95% confidence interval = [0.72, 0.86], p < 0.00001) and higher rates of insertion manipulation (risk ratio = 16.64; 95% confidence interval = [5.86, 47.24], p < 0.00001). CONCLUSION: The Baska mask offers better oropharyngeal seal pressure, but may be more difficult to insert than other laryngeal mask airways, without causing significant delays. The Baska mask appears as safe as other laryngeal mask airways, but larger trials are needed to support these findings.

Does Baska mask deserve its own niche among extraglottic airway devices? A prospective, single-arm study.

Background and Aims: A variety of extraglottic airway devices (EADs) are available. Main concerns with EADs are protection against aspiration and ability to ventilate patients with high airway pressures. Baska mask meets these criteria and is the only third-generation device available for clinical use. Methods: After institutional ethics committee approval and informed consent were obtained, this prospective study was performed in 100 adult patients undergoing surface surgeries at a tertiary referral centre. The primary outcome was the success rate of insertion, while the secondary outcomes were the sealing pressure, stability of the device and the perioperative complications of Baska mask. We then compared it with other currently used EADs. Results: The first attempt at insertion and overall success rates, showed values of 81% and 98%, respectively. Insertion was quick (median 12; interquartile range [IQR] 9-15 s). The mask sealing pressure, was 35 cmH2O (median [IQR 20-50 cmH2O]). Also, the mask remained stable in 95% of patients intraoperatively. Sore throat and dysphagia were seen in 37% and 24% of patients, respectively. No patient had laryngospasm or desaturation at any time. It compared favourably well with other EADs, while achieving higher sealing pressures. Conclusion: We found that the Baska mask performs well with excellent first attempt at insertion and overall success rates, higher sealing pressures and minimal complications compared to currently used EADs in clinical anaesthesia.

Comparison of Baska Mask Versus Proseal Laryngeal Mask Airway in Elective Surgeries Under General Anaesthesia: A Randomized Clinical Trial.

Background Baska Mask (BM) is a third-generation supraglottic airway device with a self-inflating cuff. This study aimed to evaluate the efficacy of the BM compared to ProSeal laryngeal mask airway (PLMA) regarding insertion time, ease of insertion, and oropharyngeal seal pressure in patients undergoing elective surgeries under general anesthesia for less than two hours. Methods This prospective, randomized, double-blind comparative study was done on 64 patients randomly divided into two groups, with 32 patients in the PLMA group (Group A) and 32 in the BM group (Group B). Individuals with a body mass index (BMI) of more than 30, a history of nausea/vomiting, or pharyngeal pathology were excluded from the trial. After induction with propofol 3-4 mg/kg, fentanyl 1-2 mcg/kg, and the neuromuscular blockade was achieved with atracurium 0.5 mg/kg, patients were inserted with either BM (n= 32) or PLMA (n= 32). The primary outcome measure was the time taken for insertion and ease of insertion. Secondary outcome measures included the number of attempts, oropharyngeal seal pressure (OSP), and laryngopharyngeal morbidity (trauma to lips, blood staining, and sore throat) immediately and 24 hours postoperatively. Results Demographic data were comparable and statistically insignificant. Regarding time and ease of insertion, the BM could be inserted in a lesser time of 24±1.136 seconds compared to PLMA which took 28.59±1.682 seconds, with a high success rate in the first attempt which was statistically significant. The BM provided a higher OSP (31.34 +1.638 cmH2O) when compared to PLMA (24.81±1.469 cmH2O) and was statistically significant. Complications associated with insertion trauma to the lip, blood staining, and sore throat were more in PLMA (15.6%, 15.6 %, 9.4%, respectively) compared to the BM (6.3%, 3.1%, 3.1%, respectively), and statistically insignificant. Conclusion  BM had higher first-attempt successful insertion with better OSP compared to PLMA in patients under controlled ventilation.

Comparison of clinical performance of Baska mask and Ambu AuraGain in patients undergoing surgery: A single-blinded, randomised comparative trial.

Background and Aims: The Baska mask (BM) and the Ambu AuraGain (AAG) have shown promising results in recent trials but have not been compared. Therefore, we aimed to compare the clinical performance of the BM and the AAG for airway management of adult patients. Methods: In this randomised comparative study, patients aged 18-60 years and with an expected surgical duration of less than 2 h were enroled. Patients were randomly allocated to AAG (Group A, n = 37) and BM (Group B, n = 37) for airway management. After induction of anaesthesia, an allocated supraglottic airway device (SAD) was inserted. Oropharyngeal leak pressure (OLP), time taken to insert SAD, number of insertion attempts, leak fraction (LF), first-attempt success rate, overall success rate, ease of insertion, fiberoptic view of the glottis, and complications were compared. The data were analysed using Student's t-test, Mann-Whitney U test, and Fisher's exact tests. Results: Baseline and demographic characteristics were comparable. OLP (31.32 ± 2.59 versus 27.54 ± 1.32 cmH2O) was higher (P < 0.001), and LF (6.19% ± 1.20% versus 7.24% ± 1.72%) was lower (P = 0.003) in the BM group. First-attempt and overall success rate, time taken to insert, number of insertion attempts, ease of insertion, and fibreoptic view of glottis through the SADs were statistically similar between groups. However, the incidence of sore throat (P = 0.007) and cough (P = 0.028) was higher with AAG. Conclusion: Clinical performance of BM was better than AAG as the former had higher OLP, lower LF and complications.

Comparative study of Baska mask with proseal LMA in adult patients undergoing elective surgery under general anesthesia with controlled ventilation.

Background and Aims: Several supraglottic airway devices (SGD) are available nowadays. But none has been found to be better than Proseal laryngeal mask (PLMA) in terms of oropharyngeal leak pressure (OLP). We aimed to compare OLP of newly introduced Baska® Mask with PLMA in patients undergoing elective surgical procedures under general anesthesia. Material and Methods: Totally, 80 consecutive adult patients of either sex requiring general anesthesia were randomized into two groups Group B (Baska mask, n = 40) or Group P (PLMA. n = 40). After standardized induction with propofol 2 - 2.5 mg/kg-1 and fentanyl 2 mgkg-1, and muscle relaxation with vecuronium 0.1 mgkg-1 one of the two devices was placed. OLP (primary outcome) was measured 5 minutes and 30 minutes post induction. The time needed to achieve effective airway, anatomical alignment of the device, number of attempts, leak fraction, and postoperative laryngopharyngeal morbidity were noted. Results: Both the devices could be inserted in first attempt in all the patients, but the time needed to achieve effective airway was significantly less in Group B (12.58 ± 1.81 sec vs 17.92 ± 2.45 sec, P < 0.001). The mean OLP was better in Group B at 5 min (37.6 ± 2.43 cm H2O vs 30.82 ± 3.96 cm H2O) and at 30 min (38.83 ± 1.72 cm H2O vs 30.82 ± 3.96 cm H2O; P < 0.001). Anatomical alignment of SGD with glottis (FOB grade 3 or 4 view) was significantly better in group B (34/40) as compared to group P (25/40) (p = 0.009). There was no difference in laryngopharyngeal morbidity in the two groups. Conclusion: Baska mask provided higher OLP, better alignment to the glottis and faster placement time as compared to PLMA.

An Analysis of the Comparative Efficacy Between a Third-Generation and a Second-Generation Supraglottic Airway Device in Patients Undergoing Laparoscopic Cholecystectomy.

Background and objective Supraglottic airway devices are extensively used nowadays to secure the airway and minimize postoperative airway-related complications. This study aimed to evaluate whether the Baska® mask (BM) provides higher seal pressure and a better first-time insertion compared to the laryngeal mask airway (LMA) ProSeal™ (LMA-P) in adult laparoscopic cholecystectomy. Methodology This prospective, randomized, single-blinded interventional study was performed after obtaining ethical approval from the Institutional Ethics Committee at the Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi. Sixty adult patients of both genders scheduled for laparoscopic cholecystectomy under general anesthesia were divided into two groups, with 30 patients in each group. Our study observed the number of insertion attempts, time of insertion, oropharyngeal seal pressure (OSP), number of patients requiring manipulation for proper placement of supraglottic airway devices, and ease of insertion. Results There were no significant differences in terms of insertion attempts, ease of insertion, and laryngopharyngeal morbidity between the groups. The mean OSP at five minutes was 31.55 ±2.23 cm H2O, and that at 30 minutes was 35.86 ±3.70 cm H20 in the BM group, while in the LMA-P group, it was 24.17 ±3.74 cm H20 and 25.97 ±3.79 cm H20 respectively (p<0.001). In our study, the trend of OSP continued to increase in the BM group more than in the LMA-P group during surgery. Conclusion The BM provided better OSP than the LMA-P, which was observed throughout the surgery.

Comparison of the Baska Mask® and Endotracheal Tube on Hemodynamic and Respiratory Parameters in Septoplasty Cases.

Laryngeal mask (LM) types have been used as an airway device for an alternative to the standard endotracheal tube (ETT). One of the novel type of LM, the Baska Mask®, can be a safe alternative among the airway devices. The purpose of this study is to compare the effects of the new generation supraglottic airway device the Baska Mask® and the ETT on hemodynamic parameters (heart rate, mean arterial pressure), airway pressure and end tidal carbon dioxide (EtCO2) in patients undergoing general anesthesia. After the approval of the ethics committee, 70 patients who underwent septoplasty were included in the study. Written informed consent forms were taken from these patients. Demographic data of the patients were recorded. Hemodynamic data of patients were measured and recorded preoperative, during induction, at the time of intubation 1th, 3th and 5th minute and during extubation. Also, airway pressure and EtCO2 values of the patients were measured and recorded at the time of intubation, 1th, 3th and 5th minutes. Demographic data were similar in both groups. Mean arterial pressure, heart rate and airway pressure were lower in the group 2 (the Baska Mask® group) than in the group 1 (ETT group) and the difference was statistically significant (p<0.05). EtCO2 values were similar in both groups. No patients had tube leakage. In terms of hemodynamic and respiratory parameters the Baska Mask® is more advantageous than the ETT in short-term surgeries.

Baska mask versus endotracheal tube in laparoscopic cholecystectomy surgery: a prospective randomized trial.

Background: Supraglottic airway devices have increasingly been used as the airway technique of choice in laparoscopic surgeries. This study compared the efficacy and safety of the Baska Mask with endotracheal tube (ETT) in patients undergoing elective laparoscopic cholecystectomy.Research design and methods: This single-center, prospective, randomized controlled trial recruited 60 patients aged 18-75 years with American Society of Anesthesiologists' classifications I to III. The time taken to achieve effective airway, number of attempts, ease of insertion, ventilation parameters, hemodynamics data, and pharyngolaryngeal complications were recorded.Results: The time taken to achieve effective airway was shorter for the Baska group (26.6 ± 4.7 vs. 47.2 ± 11.8 s; p < 0.001), although the first-time insertion success rate was ≥90% for both groups. The ETT group experienced more pharyngolaryngeal complications, including cough, trauma, spasm, dysphonia, and sore throat, during device insertion and removal and had higher systolic and diastolic blood pressures during intubation (p = 0.001). The Baska Mask achieved significantly lower peak airway pressure (p = 0.024) with stable oropharyngeal leak pressure ≥33 cmH2O throughout the surgery.Conclusions: The Baska Mask is a suitable alternative to endotracheal intubation in selected patients undergoing laparoscopic cholecystectomy, with shorter insertion times, fewer perioperative complications, and improved ventilatory performance and hemodynamic response.Trial registration: The trial is registered at ClinicalTrials.gov (NCT03045835), 8 February 2017.

Randomized Controlled Trial to Compare Baska® Mask versus ProSeal Laryngeal Mask Airway for General Anesthesia with Intermittent Positive Pressure Ventilation.

INTRODUCTION: A myriad of supraglottic airway devices (SADs) are developed over time to search the device that conforms to the anatomy of the human respiratory tract noninvasively, but these devices are associated with the risk of aspiration. Baska® mask (BM) is the latest addition to the family of SADs to circumvent the incidence of aspiration. AIMS OF STUDY: The aim of the study was to compare the sealing pressure and rapidity of the insertion of BM with ProSeal laryngeal mask (PLM) airway and the incidence of laryngopharyngeal morbidity between two devices. MATERIALS AND METHODS: A randomized prospective open-label study was done on sixty adult patients of the age group of 18-60 years after approval from the institutional ethical committee and registration of trial in the Clinical Trials Registry. The patients were randomly divided into two groups: Group I (BM) where BM was inserted after the induction of general anesthesia and Group II (PLM) where PLM was inserted after induction. The airway sealing pressure in BM was calculated. The mean time of insertion of respective SAD and the number of successful attempts were also recorded in both groups. For analysis of continuous variables, independent sample Student's t-test was applied, and for categorical variables, Chi-square test was used. P < 0.05 was considered statistically significant. RESULTS: The rate of successful attempts of insertion was comparable in both the groups. The mean insertion time was 14.25 ± 3.82 s in BM group and 22.01 ± 2.64 s in PLM group, which was statistically significant. The airway sealing pressure was 30.25 ± 3.34 cmH2O in BM group and 23.50 ± 4.05 cmH2O in PLM group, which was also statistically significant. CONCLUSION: BM has better ease of insertion with adequate sealing pressure as compared to PLM airway, thus reducing the chances of aspiration and offering its potential application in securing airway in emergency situations.

Efficacy of Baska mask and Laryngeal mask airway supreme during positive pressure ventilation - A comparative study.

BACKGROUND AND AIMS: Supraglottic airway devices have several roles including maintenance of a clear upper airway during general anesthesia. We primarily compared the efficacy of Baska mask (BM) and laryngeal mask airway supreme (LMAS) for the rate of first time successful placement and the seal pressure. The secondary outcome measures included laryngopharyngeal morbidity and the correct positioning of the gastric port. MATERIAL AND METHODS: A sample size of 30 was calculated in each study group. A total of 70 study participants were included in the statistical analysis of which 36 patients were in the BM group and 34 patients were in the LMAS group. RESULTS: The BM was successfully inserted in 28 patients (77.8%), whereas LMAS was successfully inserted in 33 patients (97.1%) in the first attempt (P = 0.028). The mean oropharyngeal seal pressure in the BM group was higher (33.28 ± 6.80 cm H2O) than compared to the LMAS group (27.47 ± 2.34 cm H2O) with a P value <0.001. There was no significant difference between the two groups in the incidence of postoperative laryngopharyngeal morbidity both in the immediate postoperative period (P = 0.479) and that seen 24 hours post operatively (P = 0.660). The nasogastric tube could easily be inserted in the entire study population. CONCLUSION: From the present study, it is concluded that the BM creates a higher oropharyngeal seal pressure than the LMAS. However, the BM is more difficult to insert. The incidence of postoperative laryngopharyngeal morbidity is similar in both groups.
