Antibiotics Used in Critical Care Units
Antibiotics are widely used to treat severe infections like ventilator-associated pneumonia, sepsis, etc.
They are generally given through the intravenous route for prompt control.
The IV route offers 100% bioavailability.
The drug directly enters the bloodstream.
The commonly used antibiotics include:
Carbapenems:
These are broad-spectrum antibiotics, bactericidal in nature.
Common uses include:
- Complicated intra-abdominal infections
- Multidrug-resistant bacterial infections
- Hospital-acquired pneumonia
- Complicated urinary tract infection
Beta-lactam/beta-lactamase inhibitors –
Beta-lactam antibiotics are combined with beta-lactamase inhibitors.
Bacteria produce the beta-lactamase enzyme to break down the antibiotic structure.
Beta-lactamase inhibitors inhibit this enzyme.
The inhibitors help preserve the antibiotic structure and prevent its inactivation.
These are used to treat:
- Respiratory infections
- Urinary-tract infections
- Intra-abdominal infections
- Skin-soft tissue infection
Cephalosporins –
This is a class of beta-lactam antibiotics.
These are classified into 5 generations with different antibacterial activity.
These are widely used to treat –
- Pneumonia
- Skin /soft tissue infections
- Meningitis
- Bone or joint infections
- Urinary tract infections
Glycopeptides –
These may be used as an alternative in certain people with penicillin/cephalosporin allergies.
These may be used for specific Gram-positive bacterial infections, including:
- MRSA- methicillin-resistant Staphylococcus aureus infection
- Bone/joint infections
- Pneumonia caused by susceptible Gram-positive bacteria
- Sepsis caused by susceptible Gram-positive bacteria
- Vancomycin is used in selected cases of C. difficile infection
Aminoglycosides –
These are potent antibiotics, bactericidal in nature.
They are effective against many aerobic and Gram-negative bacteria.
They may be used in selective cases:
- Sepsis
- UTI
- Certain hospital-acquired infections
- Bacterial Endocarditis

Conclusion:
The drug choice and the dose are decided by the doctor after evaluating the patient’s condition, severity of infection, susceptibility, and conformity of the causative agent.
Antibiotic stewardship is important –
Antibiotic therapy must be reviewed based on culture and susceptibility results in order to minimize antimicrobial drug resistance.
