Laryngeal Mask Airway Insertion

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.

BACKGROUND The purpose of present study was to compare and evaluate both topical lignocaine and intravenous lignocaine for laryngeal mask airway (LMA) insertion prior to propofol. Main objective was to study the conditions for LMA insertion with respect to gagging, coughing, Laryngospasm and No. of attempts for LMA insertion and also study the hemodynamic parameters in both the groups (Heart rate, SBP,DBP, MAP, SpO2) METHODS This study included 60 patients of 30 in each group, ASA I & II day care surgeries were performed in our hospital between 2019 and 2021. Patients were randomized into two groups. Group I received intravenous lignocaine 1.5 mg / kg over 30 seconds and group II received topical lignocaine 40 mg. Conditions of LMA insertion, gagging, laryngospasm, coughing were noted at the time of insertion, ECG, NIBP, SPO2 and ETCO2 were recorded according to scheduled times. RESULTS In conditions of LMA insertion, difference between both the groups was found to be significant, P < 0.05 in groups with first minute rise in heart rate, fall in Systolic blood pressure, diastolic blood pressure, mean arterial pressure was significant. At two minutes and three minutes after the LMA insertion, HR, SBP, DBP, MAP all these parameters changed slightly but these changes were statistically not significant. CONCLUSIONS Prior to Propofol induction, compared to intravenous lignocaine, topical lignocaine 10 % aerosol provided excellent conditions for the insertion of LMA without the use of neuromuscular blockers.

Background: The effects of ProSeal laryngeal mask airway (PLMA) removal and tracheal extubationon cardiovascular responses were studied in elderly hypertensive diabetic patients in a randomize double-blind study.Methods: A total of 60 elderly controlled diabetic hypertensive American Society of Anesthesiologists II & III patients were randomly allocated to two groups (n-30 of each) for PLMA insertion or endotracheal intubation. A standardized anesthetic sequence was used for induction and maintenance of anesthesia. The two groups were then compared for haemodynamic changes at the time of extubation/PLMA removal.Results: In PLMA group, heart rate increased during PLMA removal but remained elevated for only 3 minutes while mean arterial pressure remained elevated for only 2 minutes.The elevations of heart rate and mean arterial pressure were exaggerated in the extubation group and persisted for more than 5 minutes. No complication was observed in any patient and no difficulty was encountered in insertion of PLMA in any patient.Conclusion: Elderly hypertensive diabetic patients are at risk of exaggerated pressor response at the time of extubation. PLMA removal is associated with fewer hemodynamic changes than tracheal extubation and should be preferred wherever possible.J Bangladesh Coll Phys Surg 2018; 36(4): 153-158

 We compared hemodynamic responses following laryngeal mask airway insertion versus tracheal intubation in hypertensive patients who were scheduled for elective ophthalmic surgery under general anesthesia. We studied 48 controlled hypertensive patients that were randomly divided into two groups (n=24) for insertion of laryngeal mask airway (LMA) and endotracheal intubation (EI). The mean arterial blood pressure (MAP), heart rate, rate pressure product (RPP), and ST-segment changes were recorded preoperatively, immediately preintubation and 1, 3, and 5 minutes after LMA insertion or tracheal intubation in all patients and compared between two groups. There was a reduction in MAP after induction and immediately preintubation in all of patients of both groups (P<0.05). The MAP, heart rate and RPP increased immediately after both LMA insertion and tracheal intubation (P<0.05). The elevation of MAP and RPP were maintained for longer time in intubation group versus LMA group (P<0.05). There was no difference between the groups with respect to ST-segment variation. The incidence of airway injury was similar between two groups. The laryngeal mask airway insertion may be preferable to endotracheal intubation in hypertensive patients where attenuation of hemodynamic stress response is desired. © 2019 Tehran University of Medical Sciences.

Background: The ideal method to prevent hypotension due to intravenous propofol for induction of anesthesia is still debatable. The aim of the study was to compare the hemodynamic response of ephedrine and volume loading with ringer lactate in preventing the hypotension caused by propofol as inducing agent in patients scheduled for elective surgeries requiring general anesthesia with endotracheal intubation.Methods: This was prospective randomized study conducted in 40 patients of ASA physical status I, aged 20-50 years, scheduled for elective surgeries requiring general anesthesia with endotracheal intubation. Group I received intravenous ephedrine sulphate (70 mcg/kg) just before induction of anaesthesia, and patients assigned to Group II received preloading with Ringer's lactate (12 ml/kg) over the 10-15 minutes before the administration of propofol. The variables compared were heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure following induction of anesthesia till 10 minutes after intubation of trachea.Results: We found that there were increase in systolic blood pressure, diastolic blood pressure and mean arterial pressure after induction in both the groups but the difference between the groups was not significant. The increase in heart rate was found to be significantly higher in ephedrine group in comparison to volume loading group.Conclusion: Our study showed that both the methods used were equally effective in preventing hypotension induced by propofol in the adult ASA physical status I patients requiring general anesthesia with endotracheal intubation. However, the heart rate was significantly higher in patients receiving ephedrine in comparison to volume loading group.

AbstractObjective:This study aimed to compare the effects of topical and systemic lignocaine on the circulatory response to direct laryngoscopy performed under general anaesthesia.Methods:Ninety-nine patients over 20 years of age, with a physical status of I–II (classified according to the American Society of Anesthesiologists), were randomly allocated to 3 groups. One group received 5 ml of 0.9 per cent physiological saline intravenously, one group received 1.5 mg/kg lignocaine intravenously, and another group received seven puffs of 10 per cent lignocaine aerosol applied topically to the airway. Mean arterial pressures, heart rates and peripheral oxygen saturations were recorded, and changes in mean arterial pressure and heart rate ratios were calculated.Results:Changes in the ratios of mean arterial pressure and heart rate were greater in the saline physiological group than the other groups at 1 minute after intubation. Changes in the ratios of mean arterial pressure (at the same time point) were greater in the topical lignocaine group than in the intravenous lignocaine group, but this finding was not statistically significant.Conclusion:Lignocaine limited the haemodynamic responses to laryngoscopy and endotracheal intubation during general anaesthesia in rigid suspension laryngoscopy.

Aerosol Generation

Objective In 2015, Neonatal Resuscitation Program (NRP) recommended laryngeal mask airway (LMA) as an alternative to the endotracheal tube (ETT) in situations where the provider is “unable to intubate and unable to ventilate.” LMA insertion is being taught in the NRP routinely. However, endotracheal intubation is the primary method considered as the standard of care in neonatal resuscitation. LMA insertion is a relatively simple procedure with an average insertion time of < 10 seconds. Newer generation LMA can have the added advantage of reducing the risk of aerosol generation and improving the safety of the providers. Only a few recent studies have evaluated the LMA insertion skills of neonatal resuscitation providers. We wanted to study the proficiency of NRP providers in the technique of LMA insertion. We hypothesized that NRP providers would have LMA insertion skills equivalent to the standard of care (ETT insertion). Study Design A manikin-based study was done from July 2019 to December 2019. We enrolled 31 NRP providers with 1 or more years since the first certification and current valid NRP provider/instructor status. The participants were instructed to insert an ETT and LMA in the manikin. The procedures were video recorded. The time taken to insert and start ventilation with each device, including the number of attempts for successful insertion, was noted. A Likert scale questionnaire was filled by each participant indicating the level of confidence, perception of ease, and the ability to provide effective positive pressure ventilation (PPV) with each of the procedures. The paired t-test, chi-square test, and Kruskal–Wallis' test were used for the statistical analysis. Results Eight (25.8%) out of the 31 participants failed to insert any one of the devices. So, 23 providers were analyzed for the outcomes. We found that the mean duration taken to insert the ETT and LMA was not statistically different (32 vs. 36 seconds). LMA insertion had a higher failure rate compared with ETT. Providers did not perceive confidence to insert LMA when compared with ETT. They did not recognize LMA insertion as a more effortless procedure relative to endotracheal intubation. The providers felt that their ability to provide effective PPV using LMA was inferior to ETT. Conclusion The NRP certified providers in this study did not demonstrate proficiency in the insertion of LMA equivalent to the endotracheal intubation. Key Points

Hemodynamic Stability

Purpose/Background Direct laryngoscopy and endotracheal intubation after induction of anesthesia can cause a reflex sympathetic surge of catecholamines caused by airway stimulation. This may cause hypertension, tachycardia, and arrhythmias. This reflex can be detrimental in patients with poor cardiac reserve and can be poorly tolerated and lead to adverse events such as myocardial ischemia. Fentanyl, a potent opioid, with a rapid onset and short duration of action is given during induction to block the sympathetic response. With a rise in the opioid crisis and finding ways to change the practice in medicine to use less opioids, dexmedetomidine, an alpha 2 adrenergic agonist, can decrease the release of norepinephrine, has analgesic properties, and can lower the heart rate. Methods In this scoping review, studies published between 2009 and 2021 that compared fentanyl and dexmedetomidine during general anesthesia induction and endotracheal intubation of surgical patients over the age of 18 were included. Full text, peer-reviewed studies in English were included with no limit on country of study. The outcomes included post-operative reviews of decrease in pain medication usage and hemodynamic stability. Studies that were included focused on hemodynamic variables such as systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, and use of opioids post-surgery. Result Of 2,114 results from our search, 10 articles were selected based on multiple eligibility criteria of age greater than 18, patients undergoing endotracheal intubation after induction of general anesthesia, and required either a dose of dexmedetomidine or fentanyl to be given prior to intubation. Dexmedetomidine was shown to effectively attenuate the sympathetic surge during intubation over fentanyl. Dexmedetomidine showed a greater reduction in heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure than fentanyl, causing better hemodynamic stability in patients undergoing elective surgery.Implications for Nursing Practice Findings during this scoping review indicate that dexmedetomidine is a safe and effective alternative to fentanyl during induction of general anesthesia and endotracheal intubation in attenuating the hemodynamic response. It is also a safe choice for opioid-free anesthesia.
