NCT02708836

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in rate pressure product during emergence

    Difference in heart rate multiplied by systolic blood pressure measured during the \~5 minutes prior to emergence and the \~5 minutes after removal of the airway device. Heart rate is continuously monitored and recorded at one minute intervals. Blood pressure is intermittently monitored at 3 minute intervals. The two SBPs measured prior to removal of the airway device will be multiplied by the HR at those times and the RPPs will be averaged. This will be compared with average of the product of the two SBPs and their corresponding HRs measured after removal of the airway device.

    Intraoperative

Secondary Outcomes (10)

  • Time to successful ventilation via ETT

    Intraoperative

  • Change in rate pressure product during induction of anesthesia and intubation

    Intraoperative

  • Success rate of ventilation with LMA after extubation of trachea

    Intraoperative

  • Presence/ severity of cough during prior to removal of airway device

    Intraoperative

  • Presence/ severity of cough during after removal of airway device

    Intraoperative

  • +5 more secondary outcomes

Study Arms (2)

ETT only

ACTIVE COMPARATOR

Endotracheal tube intubation after induction of anesthesia. Ventilation with ETT until emergence.

Procedure: Induction of anesthesiaDevice: Laryngoscopy and placement of ETTProcedure: Ventilation via the ETTProcedure: Removal of the ETTProcedure: Emergence from anesthesia

Combined ETT/LMA technique

EXPERIMENTAL

Placement of LMA after induction of anesthesia. Intubation of trachea with ETT via LMA with fiberoptic bronchoscope. Ventilation with ETT throughout case. Removal of ETT while deeply anesthetized. Ventilation with LMA until emergence.

Combined ETT/LMA techniqueETT only

By standard method. Sizing at the discretion of the primary anesthesiologist.

Combined ETT/LMA technique

Via direct or indirect laryngoscopy. Sizing at the discretion of the primary anesthesiologist. Mallinckrodt (TM) Intermediate Hi-Lo cuffed endotracheal tube (Covidien)

ETT only

Ventilator mode, tidal volume/ ventilation pressure, respiratory rate, positive end expiratory pressure, inspired to expired ratio at the discretion of the primary anesthesiologist.

Combined ETT/LMA techniqueETT only

Either upon emergence of anesthesia after suctioning of the oropharynx and after a positive pressure breath or while deeply anesthetized after release of the pneumoperitoneum in the combined LMA/ETT group.

Combined ETT/LMA techniqueETT only

With ETT using fiberoptic bronchoscope guidance.

Combined ETT/LMA technique

After removal of the ETT. Ventilator mode, tidal volume/ ventilation pressure, respiratory rate, positive end expiratory pressure, inspired to expired ratio at the discretion of the primary anesthesiologist.

Combined ETT/LMA technique

At the discretion of primary team. Airway device (either ETT or LMA) will be removed when patient is adequately ventilating and able to respond to commands (such as "open your eyes" or "squeeze my hand").

Combined ETT/LMA techniqueETT only
