The affected person has suffered a gunshot wound to the chest, and his blood strain is dangerously low. You’ve coated the entry wound to forestall a sucking wound, however the affected person is exhaling copious bloody froth. You efficiently intubate the affected person and are bagging, with good chest rise, however the bloody froth continues to intervene with air trade. It’s time to suction the tube.
Suctioning the endotracheal tube will not be one thing most rescuers do regularly. Normally, putting an endotracheal tube ensures a patent airway with little likelihood of aspiration. However in some conditions, equivalent to chest trauma or in sufferers with COPD, you will get mucus or blood invading the tube, necessitating suction.
However suctioning the tube is extra sophisticated than merely suctioning the oral or nasal cavity. For one factor, it requires satisfactory destructive strain from a dependable transportable suction unit. It additionally requires completely different gear and particular approach, and it poses particular risks that oral/nasal suctioning doesn’t. So let’s evaluation the steps concerned in suctioning the endotracheal tube.
Keep away from Hypoxia
Earlier than you start the process, it is very important preoxygenate your affected person. One of many best risks of suctioning is hypoxia. By preoxygenating your affected person with 100% 02 and avoiding extended suctioning, you scale back the danger of hypoxia and may keep satisfactory oxygen saturation–from 95% to 100%.
Correctly Prep Your Tools
Simply as in intubating, it is best to have all of your gear laid out subsequent to the affected person. Correct readiness will make sure the process goes easily and swiftly. The very last thing you need is to be fumbling within the airway bag, searching for lubricant. Lay all the pieces out for a simple seize.
Subsequent, Comply with These Steps
- Keep common precautions.
- Select the appropriate-sized versatile catheter–one that may prolong past the tip of the endotracheal tube.
- Use sterile approach when dealing with the catheter—keep in mind, that is going INSIDE your affected person!
- Lubricate the suction catheter for ease of insertion.
- Preoxygenate the affected person for one to 2 minutes earlier than suctioning.
- Insert the catheter with out suction, then slowly withdraw whereas making use of suction and rotating the catheter.
- Suction for now not than 10 seconds to forestall hypoxia.
- Monitor the affected person carefully for indicators of hypoxia (cardiac arrhythmias, drop in 02 sat).
- Reassess the airway, endotracheal tube, and lungs and proceed ventilating.
- Repeat the suction process as crucial, however guarantee reoxygenation between suction occasions.
Selecting the Proper Suction Machine
Your selection of a conveyable suction machine will clearly be made previous to your have to suction the endotracheal tube. However it is best to contemplate such occasions when deciding on the kind of unit on your company. Listed below are a number of issues:
- Energy: Select a suction unit that provides satisfactory destructive strain, particularly within the occasion of heavy mucus or clotted blood.
- Adjustable Stress: Sure conditions require you to dial again the strain, and having a transportable suction unit that permits it is a plus. These situations embody
- Geriatric sufferers—who’ve delicate mucosal tissues that may tear simply and bleed.
- Pediatric sufferers—whose smaller oral and nasal cavities might require much less destructive strain to forestall harm and hypoxia.
- Catheter Choice: Select small, versatile catheters for endotracheal suctioning and a collection of hard-tipped catheters for oral and nasal suction.
When responding to continual sufferers, chances are you’ll be known as upon to suction a everlasting airway, equivalent to a stoma. As soon as once more, you could make use of a sterile approach to keep away from introducing contaminants. Use the identical process you’ll when suctioning the endotracheal tube, solely whenever you insert the catheter, advance till the affected person coughs.
Potential Suctioning Issues

- Hypoxia is all the time a threat throughout any kind of suctioning
- Trauma to the airway tissues
- Cardiac arrhythmias—monitor the affected person always
- Elevated intracranial strain—keep away from extended suctioning
- Lack of ability to clear mucus plug—repeat process till the airway is obvious, however you should definitely reoxygenate between suction makes an attempt
Suctioning the endotracheal tube can pose a problem, however it may be safely carried out within the discipline. Guarantee satisfactory oxygenation of your affected person, use sterile and correct approach, and have the suitable gear available. Having a conveyable suction machine that gives satisfactory destructive strain is vital, and one that may present adjustable strain can make sure that particular populations (aged sufferers and the very younger) are taken care of.
