Comparing I-Gel to Proseal Laryngeal Mask Airways in Infants: A Prospective Randomised Clinical Study.

ABSTRACT: Objective:Laryngeal mask airways and the I-gel have become increasingly popular for children undergoing minor surgery. The goal of our study is to compare I-gel and ProSeal laryngeal mask airways (LMA) in infants by analysing different parameters, such as insertion success, ventilation, haemodynamic changes and postoperative complications. Methods:For this prospective, randomised study, we selected 123 infants with an American Society of Anaesthesiologists (ASA) status I, who were undergoing minor elective lower abdominal surgery. After obtaining verbal and written informed consent from the parents, the infants were divided into two groups: the I-gel group (n=60) and the ProSeal LMA group (n=63). The times and ease of insertion, percentages of tidal volume leakage, and means and leakage pressures of these two supraglottic airways were noted. The complications and side-effects of each method were also recorded. Results:The insertion time of the ProSeal group was statistically shorter than that of the I-gel group. The peak and mean pressures and the leakage percentage of the ProSeal group were statistically lower than those of the I-gel group. The leakage pressure of the ProSeal group was statistically higher than the I-gel group. Conclusion:In comparison with I-gel, the use of ProSeal LMA in infants' anaesthesia presents many advantages, such as the ease of its insertion, better oropharyngeal leakage pressure and less mucosal hyperaemia.

Project description:The Guardian Laryngeal Mask Airway (G-LMA) is a new silicone-based single-use extraglottic device with the drainage port and a cuff pilot valve with pressure indicator. The aim of this study is to compare the clinical performance of this laryngeal mask airway with ProSeal laryngeal mask airway (P-LMA).In this prospective randomized study, we included adult patients with ASA grading I and II scheduled for elective surgery requiring supine position under total intravenous anesthesia. The patients were randomly allocated to two groups, 40 in each. G-LMA and P-LMA were used in groups G and P respectively. The cuff of each device was air inflated to 60 cmH2O. The primary outcome was to compare the airway sealing pressure and the secondary outcome was to compare the efficacy and safety of these two devices with respect to insertion success, insertion time, ease of insertion, volume of air for cuff inflation to 60 cmH2O, intracuff pressure measurement, gastric tube insertion attempt, gastric tube insertion time, Fiberoptic laryngeal view, and postoperative pharyngolaryngeal morbidity.The airway sealing pressure at 60 cmH2O cuff pressure was significantly greater in G-LMA than P-LMA (p?=?0.04).The first successful attempt of both groups were comparable (p?=?1.000). Insertion time was significantly shorter in G-LMA than P-LMA (p?<?0.0001). The first successful attempt for the gastric tube insertion in both groups was comparable (p?=?0.431). Gastric tube insertion time was less in G-LMA than in P-LMA (p?<?0.0001). The volume of air for cuff inflation to 60 cmH2O was more in G-LMA than in P-LMA (<0.0001). The intracuff pressure measurement at 30, 60, 90 and 120 minutes were comparable (p?=?0.823, 0.182, 0.870, 0.658).We did not find differences in ease of insertion (p?=?0.60); Fiber-optic positions of airway devices were comparable (p?=?0.83). In addition, blood staining (p?=?1.00), sore throat and dysphagia at 1, 2 and 24 hour (p?=?1.00) were comparable in both groups.The Guardian laryngeal mask airway was associated with high airway sealing pressure with a quicker insertion of the device as well as gastric tube.Clinical Trial.gov Identifier: NCT02063516.

Project description:BackgroundProSeal (PLMA) and Supreme (SLMA) laryngeal mask airways are effective ventilator devices with distinctive designs that may require different anaesthetics for insertion. Sevoflurane induction provides acceptable conditions for laryngeal mask insertion, and remifentanil significantly decreases the minimum alveolar concentration of sevoflurane required for that insertion. The study aimed to evaluate the optimal end-tidal (ET) sevoflurane concentration for successful insertion of PLMA versus SLMA in patients receiving a remifentanil infusion without a neuromuscular blocking agent.MethodsAltogether, 45 patients ASA (American Society Anaesthesiologists) physical status I-II, aged 18-60 years were scheduled for elective ambulatory surgery. Exclusion criteria were a difficult airway, recent respiratory infection, reactive airway, obstructive sleep apnoea syndrome, gastric aspiration's risk factors, pregnancy, and lactation. Patients were randomly allocated to receive the SLMA or the PLMA. Sevoflurane induction with co-administration of remifentanil was performed at an effect-site concentration of 4 ng mL- 1. ET50 was calculated with a modified Dixon's up-and-down method (starting at 2.5% in steps of 0.5%). Predetermined sevoflurane concentration was kept constant during the 10 min before LMA insertion. Patient's response to LMA insertion was classified as "movement" or "no movement". Sevoflurane ET50 was determined as the midpoint concentration of all the independent pairs that manifested crossover from "movement" to "no movement".ResultsThe ET50 sevoflurane concentration co-administered with remifentanil required for PLMA insertion was 1.20 ± 0.41% (95% confidence interval 0.76 to 1.63%). For SLMA insertion, it was 0.55 ± 0.38% (95% confidence interval 0.14 to 0.95%) (p = 0.019).ConclusionsThe end-tidal sevoflurane concentration with co-administered remifentanil required to allow insertion of the SLMA was 54% lower than that needed for inserting the PLMA.Trial registrationClinicaltrials.gov identifier: NCT03003377.

Project description:BACKGROUND:The intubating laryngeal mask Fastrach™ is considered a gold standard for blind intubation as well as for fibreoptic guided intubation via a laryngeal mask. Recently, a single use version of the mask has been introduced. We compared the Fastrach single use with the new, low-priced single use intubating laryngeal mask Ambu Aura-i™. We hypothesised that the LMA Ambu Aura-i and the LMA Fastrach are comparable with respect to success rates for mask placement and blind tracheal intubation through the LMA device. METHODS:A prospective, randomised clinical trial. University Hospital Schleswig-Holstein, Campus Kiel, from April 2011 to April 2012. Eighty patients undergoing general anaesthesia with planned tracheal intubation were randomised and enrolled in the study. Blind intubation was performed with either laryngeal mask using two different tracheal tubes (Rüsch Super Safety Silk™ and LMA ETT™). A crossover-design was performed after an unsuccessful procedure. Primary outcome measure was the overall success rate of blind intubation. Secondary outcome measures were the time to the first adequate ventilation, a subjective handling score, and a fibreoptic control of placement, as well as the success rate of mask placement, time for mask removal after successful intubation, differences in airway leak pressure, and the incidence of postoperative sore throat and hoarseness. RESULTS:The success rate of tracheal intubation with the Fastrach for the first and second attempt was significantly better compared with the Ambu Aura-i. Tracheal intubation was also significantly faster (14.1 s. ±4.4 versus 21.3 s. ±9.0; p < 0.01), and the time interval for mask removal after successful intubation was significantly shorter using the Fastrach device (24.0 s. ±8.2 versus 29.4 s. ±7.5; p < 0.001). There were no significant differences between groups regarding the incidence of postoperative sore throat and hoarseness. CONCLUSION:Both laryngeal mask devices are suitable for ventilation and oxygenation. Blind intubation remains the domain of the LMA Fastrach, the Ambu Aura-i is not suitable for blind intubation.
