Effective Suctioning in Clinical Settings: Duration and Safety Considerations

-

What is suctioning and its effects?

Suctioning of fluid during surgery is a common practice that helps to maintain a clear and safe surgical field. It is typically done using a suction device, such as a surgical suction device, which is a tube connected to a source of suction, such as a vacuum.

Fluid suctioning during surgery can be used to remove blood, saliva, and other bodily fluids that may accumulate in the surgical field. This is important for maintaining visibility for the surgeon and preventing fluid from entering the patient's lungs  and causing complications. Suctioning can also be used to remove debris, such as bone chips, during orthopedic procedures.

During surgery, the surgical team may use various types of suction catheters to remove fluid and debris. These can include rigid suction catheters, which are used to clear large amounts of fluid, and soft suction catheters, which are used to remove smaller amounts of fluid. Additionally, suction may be used during surgery to clear the airway of a patient.

Suctioning can be performed via:

1. Oral suctioning – Through the mouth.

2. Nasal suctioning – Through the nose.

3. Endotracheal suctioning – Through a tube inserted into the trachea (for patients on mechanical ventilation).

4. Tracheostomy suctioning – Through a tracheostomy tube.

What complications can happen due to suctioning?

Suctioning can also cause trauma to the tissue, which can lead to bleeding, inflammation, and other complications. It can also cause hypotension due to decreased blood flow and decreased blood pressure, and it can also cause bronchospasm and laryngeal spasms. In addition, suctioning can also lead to hypoxemia, which is a decrease in the amount of oxygen in the blood.

 How much time suctioning can be used?

For intermittent suctioning (e.g., clearing a blocked airway), suctioning should typically last no longer than 10-15 seconds at a time. Prolonged suctioning can lead to oxygen desaturation, tissue trauma, and arrhythmias. If suctioning is needed for a longer duration, the procedure should be broken up into several short sessions with breaks in between to allow for recovery of the oxygen levels.

For continuous suctioning (such as with a tracheostomy or for secretions that need ongoing management), it can be maintained, but only as long as needed, and regular assessment is crucial to avoid complications like mucosal damage or oxygen desaturation.

Guidelines for Safe Suctioning:

1. Limit suctioning time to avoid causing hypoxia or damage to the mucosal lining.


2. Ensure proper technique to prevent trauma or infection (sterile technique for invasive suctioning).


3. Monitor oxygen levels during and after suctioning to avoid hypoxia.


4. Consider patient comfort and avoid excessive suctioning if not clinically necessary.

It is important to consult with a healthcare professional for guidance on how long suctioning should be used for your specific situation. Additionally, it's important to take breaks in between suctioning sessions, and not to use suctioning excessively as it can cause irritation or even injury to the airway.

How to prevent retractor fatigue during surgery?

  Retractor Fatigue During Surgery A retractor is a surgical instrument used to hold back or separate tissues during a surgical procedure. It is typically a flat or curved blade with a handle that can be adjusted to various angles. Retractors are commonly used in various types of surgeries, such as abdominal, thoracic, and orthopedic procedures, to provide better visibility and access to the surgical site. They can also be used to hold organs or other structures in place during a procedure. Retractor fatigue during surgery refers to the physical exhaustion that can occur in surgeons when using retractors for prolonged periods of time during an operation. This can lead to decreased precision and increased risk of errors.  Manual retraction, a task performed to expose the surgical site, poses a high risk for musculoskeletal disorders that affect the hands, arms, shoulders, neck, and back(1).   To prevent retractor fatigue, surgeons may take frequent breaks, use assistive devices, or

Difference between anesthesia machine & ventilation machine

  An   anaesthetic machine   ( British English ) or   anesthesia machine   ( American English ) is a   medical device   receives medical gases (oxygen, nitrous oxide, air) under pressure and  accurately controls the flow of each  gas individually. A gas mixture of  the desired composition at a define  flow rate is created before a known  concentration of an inhalational  agent vapour is added. Gas and  vapor mixtures are continuously  delivered to the common gas outlet  of the machine, as fresh gas flow  (FGF) , and to the breathing system  and patient . Components of anesthesia machine: It consists of  1.Gas supplier 2. Pressure gauges 3. Pressure regulators (reducing  valves) 4. Flowmeters 5. Vaporizers 6. Common gas outlet 7. A variety of other features, e.g.  high-flow oxygen flush, pressure  relief valve and oxygen supply  f ailure alarm and suction  apparatus 8. Most modern anesthetic  machines or stations incorporate  a circle breathing system.   The machine is commonly used to

Autoclave principle, working and its types

Autoclave  principle, working and its types  Steam Sterilizer / Autoclave :    The autoclave is a sealed device (similar to a pressure cooker) that kills microorganisms using saturated steam under pressure .  Principle :   The use of moist heat facilitates the killing of all microorganisms, including heat-resistant endospores which is achieved by heating the materials inside the device at temperatures above the boiling point of water.    Method :   Moist heat in the form of steam under pressure causes the denaturation & coagulation of proteins by following steps . 1.Conditioning :   The usual procedure is to heat at 1.1 kilograms/square centimeter (kg/cm2) [15 pounds/square inch (lb/in.)] steam pressure, which yields a temperature of 121°C. At 121°C, the time of autoclaving to achieve sterilization is generally considered to be 15-20 min, depending on the volume of the load.    2. Exposure : Direct saturated steam contact is the basis of the steam sterilization process. For a s
