Limiting Emergence Phenomena After General Anesthesia With Combined LMA and ETT Airway Management Technique
Limiting Emergence Phenomena After General Anesthesia for Laparoscopic Surgery With Combined Laryngeal Mask Airway and Endotracheal Tube Airway Management Technique
Who can join
Ages 18 and older · All sexes
Full eligibility criteria
Inclusion Criteria: * ASA 1-3 * Patients undergoing elective laparoscopic surgery Exclusion Criteria: * Individuals who cannot provide consent * Individuals who would require translation services to provide consent * Prisoners * Parturients * Non-fasted patients (as per HMC Anesthesiology Department NPO policy) * Patients felt to be high risk for gastric reflux and pulmonary aspiration (those with gastroparesis, symptomatic GERD, etc.: at the discretion of primary anesthesia team) Those patients with anticipated difficult airway requiring maintenance of spontaneous ventilation (awake intubation)
About the study
Emergence from general anesthesia with a laryngeal mask airway compared with an endotracheal tube has been shown to favorable with respect to limiting emergence phenomena such as coughing, straining, restlessness, and sympathetic stimulation leading to hypertension and tachycardia.
Many anesthesiologists would prefer the use of an ETT to an LMA in cases in which higher ventilation pressures may be required, in those patients who are perceived to be high risk for reflux and pulmonary aspiration of gastric contents, as well as during cases that allow the anesthesiologist to have little accessibility the airway.
The aim of this study is to investigate an airway management technique that would allow for the benefits of the ETT in terms of a secure airway for the duration of the surgical procedure as well the potential for less emergence phenomena seen when emerging with an LMA.
