Study Description
Brief Summary:
The purpose of this study is to determine whether exchange of the double lumen tube before emergence with a laryngeal mask airway (Proseal) or a tracheal tube will reduce cough at emergence.

Condition or disease Intervention/treatment Phase
Cough Laryngospasm Apnea Desaturation Voice Hoarseness Device: LMA Proseal Device: Tracheal tube Phase 3

Detailed Description:
Intubation with a double lumen tube is often the preferred method to ensure isolation of the lung and proper exposition of the surgical site during thoracoscopies and thoracostomies. Unfortunately, because of the length and diameter of the double lumen tube, it is known to cause more irritation in the upper airways thereby inducing cough at emergence. In turn, cough has been associated with numerous multisystemic complications. Severe respiratory complications include laryngospasm or upper airway obstruction, desaturation, vocal cord injury, tracheal and bronchial ruptures. The purpose of this study is to determine whether exchange of the double lumen tube before emergence with a laryngeal mask airway (Proseal) or a tracheal tube will reduce cough at emergence.

Arms and Interventions

Arm Intervention/treatment
No Intervention: Control
The double lumen tube is kept until extubation; there is no exchange with any tracheal tube or LMA.
Active Comparator: Proseal
The double lumen tube is exchanged with a Proseal (LMA) before emergence according to the study protocol.
Device: LMA Proseal

Once surgery is completed, the patient is transferred onto a gurney. Train of four is checked. Patient is ventilated with 100% oxygen. Remifentanil 0.5 ug/ml IV is administered. 30 seconds to 1 minute later, secretions are suctioned. Depth of anesthesia is ensured by deflating, inflating, then deflating the tracheal balloon of the DLT and checking for absence of movement, swallowing, or coughing. The DLT is removed, then the LMA proseal is inserted. Respiratory and hemodynamics parameters are noted. Tolerance of the exchange (presence of cough, movement, laryngospasm, desaturation) is noted. Inhalational gas is stopped. Reversal agent is administered if appropriate. Spontaneous breathing is titrated for <12 with boluses of fentanyl 25ug or sufentanil 2.5ug q 5mins.

If failure to insert Proseal occurs, a second attempt is made after deepening anesthesia with propofol 1mg/kg and remifentanil 0.5ug/kg IV. If failure occurs again, the patient is intubated with a tracheal tube.

Other Name: Proseal, laryngeal mask airways
Active Comparator: Tracheal tube
The double lumen tube is exchanged with a tracheal tube before emergence according to the study protocol.
Device: Tracheal tube
Once surgery is completed, the patient is transferred onto a gurney. Train of four is checked. Patient is ventilated with 100% oxygen. Remifentanil 0.5 ug/ml IV is administered. 30 seconds to 1 minute later, secretions are suctioned. Depth of anesthesia is ensured by deflating, inflating, then deflating the tracheal balloon of the DLT and checking for absence of movement, swallowing, or coughing. The DLT is removed, then a tracheal tube (size 7 for women, size 8 for men) is inserted. Respiratory and hemodynamics parameters are noted. Tolerance of the exchange (presence of cough, movement, laryngospasm, desaturation) is noted. Inhalational gas is stopped. Reversal agent is administered if appropriate. Spontaneous breathing is titrated for <12 with boluses of fentanyl 25ug or sufentanil 2.5ug q 5mins.
Other Name: Single lumen endotracheal tube
