Periacal Cyanosis: Definition, Causes and Treatment


Cyanosis is a bluish, grayish, or dark purple coloration of the membranes of the skin or mucous membranes, manifested mainly in the lips, which is caused by a deficiency of oxygen in the lungs and by an excess of carbon dioxide in the lungs. Blood.

Cyanosis may be secondary to any condition that interferes with the ability of air to enter the respiratory tract or due to an overdose of certain hallucinogenic substances or asphyxia.

The skin color is determined by the amount of pigment it contains and the blood that flows through it. Blood rich in oxygen is bright red, which, when it lacks oxygen, is darker or more bluish. People who lack oxygen in their blood may suffer from cyanosis.


Cyanosis can be caused by a wide variety of disorders, among which are:

  • Pulmonary hypertension (a complication of Chronic Obstructive Pulmonary Disease).
  • Pneumonia.
  • Bronchiolitis in children under two years or bronchitis in older than two.
  • COPD (Chronic Obstructive Pulmonary Disease).
  • Asthma.
  • Congestive heart failure
  • The phenomenon of Raynaud.
  • La epiglottitis.
  • Convulsions
  • Drug overdose.
  • Suffocation or suffocation

Symptoms of Cyanosis

Symptoms of perioral cyanosis may involve several abnormalities that are not necessarily indicative of the condition. However, one of the most apparent manifestations is blue dye on the skin’s outer surface, mucous membranes, or the lips.

Other less obvious symptoms of cyanosis, which could also indicate other health problems, include anxiety, excessive breathing, and decreased appetite.


Tachycardia, a sensation of lethargy, and inflammation of the skin regions such as the face or eyes can also be symptoms that lead to the patient presenting cyanosis.

Cyanosis is a state where there is an abnormally low level of oxygen in the bloodstream, which can cause many health-related problems.


  • Supplemental oxygen (Nasal Cannula, Mascara Ventury, Macara with reservoir bag for non-rebreathing or, in critical cases, mechanical ventilation).
  • Antibiotics In case there is an infection.
  • Inhalers and Nebulizations. They are supplied to reduce respiratory distress (Beclomethasone, Salbutamol, and Ipratropium Bromide).
  • Diuretics are applied to patients who are sometimes very laden with liquids, leading them to present respiratory distress and, therefore, perioral cyanosis.
  • Respiratory Therapy is done so that the patient has a good quality of life, improving their breathing pattern.

After this treatment, the patient will begin to improve their symptoms, decreasing their perioral cyanosis.
