Brief Summary:
To investigate use of aerosol combined with intravenous antibiotics for the treat of multi-drug resistance gram negative bacterias diagnosed ventilator-associated pneumonia in intensive care unit in a hospital.

Condition or disease Intervention/treatment Phase
Ventilator Associated Pneumonia Multi-antibiotic Resistance Drug: aerosol antibiotics Not Applicable

Detailed Description:
Ventilator-associated pneumonia (VAP) refers to the endotracheal tube or tracheostomy patients pneumonia after 48h of mechanical ventilation, mechanical ventilation is one of the most common and most serious complications, hospital acquired is An important cause of pneumonia. According to the onset time of VAP, VAP can be divided into early-onset VAP and late-onset VAP. The time limit is mechanical ventilation for 4 days, in which early-onset VAP (mechanical ventilation ≤ 4d) is mainly caused by pathogens sensitive to most antibacterial drugs (such as methicillin-sensitive Staphylococcus aureus, Streptococcus pneumoniae, etc.); late-onset VAP ≥ 5D occur during mechanical ventilation, mainly caused by multi-drug resistant (multi-drug resistance, MDR) (such as P. aeruginosa, Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus). Some early-onset VAPs can also be caused by MDR. Therefore, MDR has become the main pathogen of VAP, especially Gram-negative bacilli. Studies have shown that VDR caused by MDR has a mortality rate of 76% and an attributable mortality rate of 20-30%. Such bacteria are not sensitive to commonly used antibacterial drugs in the clinic, and sensitive antibiotics, such as aminoglycosides, have a large systemic side effect, thereby limiting clinical use. Therefore, in theory, nebulized inhaled sensitive antibiotics can achieve high drug concentrations in lung tissue, and lower blood concentrations can avoid or reduce systemic side effects.

Arm Intervention/treatment
Experimental: aerosol combined group
aerosol combined intravenous antibiotics group,amikacin 15mg/kg, qd
Drug: aerosol antibiotics
use of inhaled Antibacterial drug combined with intravenous antibiotics to treatment multiple drug resistance GNB ventilator associated pneumonia.

No Intervention: No intervention group
this group follow the usual treatment without any intervention

Primary Outcome Measures :
  1. CPIS score changes [ Time Frame: 14 days ]
    use clinical pulmonary infection score scale to evaluate score change from baseline for every patient

  2. renal function changes [ Time Frame: 14 days ]
    record changes in renal function assessed by SCr, blood urea nitrogen,etc.

Secondary Outcome Measures :
  1. ventilator free days in 14 days [ Time Frame: 14 days ]
    record number of days with no ventilator support from day 1 through day 14

  2. 14-day mortality rate [ Time Frame: 14 days ]
    rate of mortality from day 1 to day 14

  3. Drug resistance induction rate [ Time Frame: 14 days ]
    Drug resistance induction rate is The number of cases of antibiotic-resistant species from the previous increase divided by the total number of patients included
