Concentrations of Remifentanil for Extubation (REMEX)

16. marts 2016 opdateret af: LUIS ALBERTO TAFUR B, Seganest

Effect of Two Plasma Concentrations of Remifentanil Through Target Controlled Anesthesia on Frequency and Intensity of Coughing During Extubation: Randomized Controlled Clinical Trial

Condition of the State: (terminated, recruiting, etc.) Terminated

Study Design: Main Objective:

Compare the frequency and intensity of coughing at the time of extubation with two infusions of remifentanil that predict a plasma concentration (PC) of 3 - 4 and 2 - 3 ng/ml, through the technique of target controlled anesthesia

Phase of the study:

Phase IV

Intervention:

Drug: U Extubation

Other Names:

Concentration 2 - 3 ng/ml Dose of remifentanil according to the randomization: Letter U between 2 - 3 ng/ml. The infusions that were used to reach the (PC) target were: Group U = 2 - 3 ng/ml. 20 years old - 6.0 mcg/Kg/h, 30 years old - 5.7 mcg/Kg/h, 40 years old - 5.3 mcg/kg/h, 50 years old - 5.0 mcg/kg/h, 60 years old - 4.6 mcg/kg/h, 70 years old - 4.3 mcg/kg/h, 80 years old - 4.0 mcg kg/h.

Drug: Extubation T

Other Names:

Concentration 3 - 4 ng/ml Dose of infusion of remifentanil to reach a (PC) 3 - 4 ng/ml, in the following manner: The assistant placed the infusion balloon in such a way that it could not be seen by the treating anesthesiologist, he proceeded to open the corresponding wrapping according to the consecutive which corresponds to the patient. The remifentanil dose was adjusted according to the randomization: Group T = 3 - 4 ng/ml. 20 years old - 9.0 mcg/Kg/h, 30 years old - 8.5 mcg/Kg/h, 40 years old - 8.0 mcg/kg/h, 50 years old - 7.5 mcg/kg/h, 60 years old - 7.0 mcg/kg/h, 70 years old - 6.5 mcg/kg/h, 80 years old - 6.0 mcg kg/h.

Number of arms:

2

Masking:

The patient had masking with regards to the anesthetic procedure from the unfamiliarity per se of the same and by agents used in this that induced anxiolysis and hypnosis.

To guarantee the masking to the viewer, which was the treating anesthesiologist, a nurse was trained in the adjustment of the infusion balloon. Ten minutes before concluding the procedure and by request of the anesthesiologist, the nurse proceeded to locate balloon in such a way that the infusion could not be seen by the anesthesiologist, then opened the envelope and adjusted the infusion according to the randomization (U) o (T). The evaluation of the cough, its intensity and the Ramsay were under the care of the anesthesiologist, who was unaware of the awakening infusion.

Allocation:

Two were allocated for the use: Concentration of remifentanil of 2 - 3 ng/ml (group U) and concentration of remifentanil of 3 - 4 ng/ml (group T).

Recruitment:

A patient was recruited between the period of January 2011 and July 2012.

Tidsramme
Cough
Tidsramme: It is evaluated by the scale of cough over a two hour period after surgery: is assessed at 5 minutes turned off the halogenated inhalation anesthetics, thereafter every minute until the patient responds to verbal stimulus and can be extubated

Number of episodes and duration of cough that occur when the patient responds to verbal stimulus and extubated.

Cough Scale

  • Grade 0 = No cough
  • Grade 1 = Mild (only episode of cough)
  • Grade 2 = Moderate (more than 1episode of cough during less than 5 seconds)
  • Grade 3 = Severe (More than one episode of cough that lasted more than 5 seconds or purposeless movements of the extremities).
