From the Research
Coughing during hemodialysis (HD) can lead to serious complications, including needle dislodgement, increased blood pressure, fluid shifts, and discomfort, and should be addressed promptly to prevent adverse outcomes, as highlighted in recent studies 1.
Complications of Coughing During HD
Coughing during HD can lead to several problems, including:
- Needle dislodgement: Forceful coughing may cause the dialysis needles to shift or come out, interrupting treatment and risking blood loss.
- Increased blood pressure: Coughing can temporarily raise blood pressure, which may be problematic during dialysis.
- Fluid shifts: Coughing can affect fluid balance, potentially impacting the effectiveness of fluid removal during treatment.
- Discomfort: Persistent coughing can cause physical discomfort and anxiety for the patient.
Addressing Coughing During HD
To address coughing during HD:
- Identify the cause: Common reasons include fluid overload, allergies, or respiratory infections, as noted in studies 2, 1.
- Treat underlying conditions: If due to an infection or allergy, appropriate medication may be prescribed.
- Adjust fluid removal: If coughing is due to fluid overload, the dialysis prescription may need adjustment, as discussed in 1.
- Use cough suppressants: Over-the-counter options like dextromethorphan may help, but consult your nephrologist first.
- Proper positioning: Sitting upright can help reduce coughing.
- Humidification: Using a humidifier during treatment may ease respiratory irritation.
Importance of Prompt Action
It is essential to inform your dialysis team if you experience persistent coughing during treatment, as they can assess the situation and make necessary adjustments to ensure safe and effective dialysis, and prevent complications such as those discussed in 3 and 4.
