Background: Laryngeal mask airway (LMA) does not provide definitive airway protection from pulmonary aspiration of potential regurgitated gastric contents. LMA supreme, a recent supraglottic (extraglottic) airway device, shows promising results. Thus, aim of study to evaluate the role of supreme laryngeal mask airway (SLMA) in airway management of patients operated with laparoscopic procedures under general Anaesthesia. Methods: The prospective observational study comprised of 274 patients of ASA grade 1 and 2 scheduled for short elective laparoscopic procedures (<1hr.30min) who provided consent. Patients were anaesthetised according to standard protocol, appropriate size of SLMA was chosen and inserted; and complications were noted. Post SLMA removal, recovery and trauma of throat were noted. Postoperative complications such as nausea, vomiting, and throat pain were noted. Binary logistic regression model and Chi-square test of association was performed to analyse data (P<0.05). Results: Most participants were female (n=260) with mean age of 31.42±7.24 years. Mean duration of surgery and recovery time was 37.3±5.84 min and 5.85±1.93 min respectively. SLMA size 3 was commonly used (n=245) and majority of insertions were successful in the first attempt (n=244). Post insertion, SLMA had adequate length (n=208) Throat pain (n=37) and vomiting (n=38) were common post-operative complications observed in the patients. A significant association was observed between operative procedure and complication (P=0.0004) and number of attempts (P=0.0004) with trauma being significant (P=0.0039). Trauma was associated with gender (P=0.08) and body weight (P=0.006). Conclusion: SLMA can be used as a standalone supraglottic (extraglottic) airway device for airway management in laparoscopic surgeries.

Background The intubating laryngeal mask airway (ILMA) was designed using the characteristics of healthy-weight subjects but was shown to be an effective airway device in morbidly obese patients. The authors compared airway management quality in morbidly obese and lean patients with use of the ILMA. Methods Fifty morbidly obese and 50 lean patients (mean body mass indexes, 42 and 27 kg/m, respectively) were enrolled in this prospective study. After induction of general anesthesia, characteristics of airway management were judged on safety and efficiency parameters, including success rate at ventilation and intubation and airway management quality criteria, such as the number of patients who required adjustment maneuvers, the number of failed tracheal intubation attempts, the total duration of airway management, and an overall difficulty visual analog scale score. Results The ILMA was successfully inserted and adequate ventilation through the ILMA was achieved in all 100 patients. The success rates of tracheal intubation through the ILMA were similar in obese and lean patients (96% and 94%, respectively). The numbers of failed blind tracheal access attempts and patients who required airway-adjustment maneuvers were significantly reduced in obese patients as compared with lean patients. Four obese patients experienced transient episodes of oxygen desaturation (oxygen saturation &lt; 90%) before adequate bag ventilation was established with the ILMA. Conclusion The authors confirmed that the ILMA was an efficient airway device for airway management of both lean and obese patients. In the conditions of this study, the authors observed that airway management with the ILMA was simpler in obese patients as compared with lean patients.

Introduction: Airway management is a crucial skill for the clinical anaesthesiologist. It is an integral part of general anesthesia, allowing ventilation and oxygenation as well as a mode for anesthetic gas delivery. The laryngeal mask airways (LMA) have become popular in airway management as a missing link between facemask and tracheal tube in terms of both anatomical position and degree of invasiveness. Haemodynamic stability is an important aspect to the anaesthesiologist for the benet of the patients especially during intubations, laryngeal mask insertion. Laryngoscopy and endotracheal intubation can cause striking changes in Haemodynamics as result of intense stimulation of sympathetic nervous system. The aim of this study was to evaluate the hemodynamic changes between endotracheal intubation and laryngeal mask airway insertion. Material And Methods: This was a prospective observational study on 46 patients of ASA I-II status divided into 2 groups of 23 each. In the ETT (Endotracheal tube) group endotracheal intubation was done using Macintosh laryngoscope by using portex cuffed endotracheal while in LMA (Laryngeal mask airway) group laryngeal mask airway was inserted according to the standard recommendation. Heart rate, Systolic, Diastolic and Mean arterial pressure and dysrhythmias were monitored. Results: The two groups were comparable in terms of demographic data as there were no signicant differences between the 2 groups in terms of age, sex, duration of surgery, ASA grades and MPC classication. Heart rate (HR), Systolic blood pressure (SBP), Diastolic blood pressure(DBP), Mean arterial pressure (MAP) remains on higher side in ETT group than LMA group which was statistically signicant. P<0.05. Dysrhythmias were noted in 2 patients of ETT group while LMA group did not notice any dysrhythmias. Conclusion: This study demonstrated that there is a haemodynamic response consisting of an increase in Heart rate, SBP, DBP and MAP that comes with ETT insertion as well as with LMA insertion. However, the response caused by ETT insertion is signicantly greater than that caused by LMA insertion.

Abstract Background The obstetric airway is a significant cause of maternal morbidity and mortality. Endotracheal intubation is considered the standard of care but the laryngeal mask airway (LMA) has gained acceptance as a rescue airway and has been incorporated into the obstetric airway management guidelines. In this randomized controlled equivalence trial, we compared the Supreme LMA (SLMA) with endotracheal intubation (ETT) in managing the obstetric airway during cesarean section. Methods Parturients who underwent elective cesarean section under general anesthesia were randomized to receive either an SLMA or ETT as their airway device. Our primary outcome was first-attempt insertion success. Successful insertion was defined as adequate bilateral air entry with auscultation and the presence of end-tidal carbon dioxide on the capnogram. The first-attempt insertion success rate was compared using the Chi-Square test. Secondary outcomes included time-to-ventilation, seal pressure, ventilation/hemodynamic parameters, occurrence of clinical aspiration, foetal outcomes, and maternal side effects associated with the airway device. Results We recruited 920 parturients (460 SLMA, 460 ETT) who underwent elective Caesarean section under general anesthesia. Patient characteristics were similar between the groups. First attempt success was similar (Odds Ratio--ORSLMA/ETA: 1.00 (95%CI: 0.25, 4.02), p = 1.0000). SLMA was associated with reduced time to effective ventilation (Mean Difference--MD -22.96; 95%CI: -23.71, -22.21 seconds) compared to ETT group (p<0.0001). Ventilation parameters, maternal and fetal outcomes were similar between the groups, and there was no aspiration. Conclusions SLMA could be an alternative airway management technique for a carefully selected low-risk obstetric population, with similar insertion success rates, reduced time to ventilation and less hemodynamic changes compared with ETT. Our findings are consistent with the airway guidelines in recommending the second line use of LMA in the management of obstetric airway.
