Study Details

Study Description

Brief Summary

The study is a case-controlled observational trial. Sixty patients will be divided into 2 groups (good or poor sleepers) depending on their first postoperative night Bispectral index data. Firstly, this study aims to characterise the gut and lung microbiota in patients with lung cancer treated with surgery. Secondly, it aims to evaluate microbiota and its influence on plasma kynurenine.

Condition or Disease Intervention/Treatment Phase
  • Drug: General anesthesia

Arms and Interventions

Arm Intervention/Treatment
Group good sleepers

Duration of sleep was defined as the duration of all Bispectral Index data below 80 in the 12 hours of monitoring (from 20:00pm to 06:00am). Sleeping time are more than six hours.

Drug: General anesthesia
For maintenance of propofol anesthesia, total intravenous anesthesia was administered by using propofol (Fresenius Kabi, Austria GmbH) at a plasma target concentration (Marsh pharmacokinetic model software) of 2.5-4 μg/ml. Remifentanil (0.2-0.5 μg/kg/min) was given to all patients during the operation. Additional cisatracurium (0.05 mg/kg)and fentanyl (30-50 μg at the end of surgery) were used as needed, in accordance with the clinical requirements.

Group poor sleepers

Duration of sleep was defined as the duration of all Bispectral Index data below 80 in the 12 hours of monitoring (from 20:00pm to 06:00am). Sleeping time are less than two hours.

Drug: General anesthesia
For maintenance of propofol anesthesia, total intravenous anesthesia was administered by using propofol (Fresenius Kabi, Austria GmbH) at a plasma target concentration (Marsh pharmacokinetic model software) of 2.5-4 μg/ml. Remifentanil (0.2-0.5 μg/kg/min) was given to all patients during the operation. Additional cisatracurium (0.05 mg/kg)and fentanyl (30-50 μg at the end of surgery) were used as needed, in accordance with the clinical requirements.

Outcome Measures

Primary Outcome Measures

  1. lung and gut microbiota [from baseline to postoperative 72 hours]

    this study will characterise the lung and gut microbiota in 2 groups of 30 patients

Secondary Outcome Measures

  1. Bispectral index data [the first postoperative night]

    this study will characterise the Bispectral index data in 2 groups of 30 patients

  2. plasma kynurenine concentrations [baseline and the first postoperative night]

    this study will characterise the plasma kynurenine concentrations in 2 groups of 30 patients
