Risks associated with suctioning include hypoxemia, microatelectasis, and cardiac dysrhythmias. Suctioning removes secretions and oxygen. To minimize both the amount of oxygen removed and mucosal trauma, suction is applied when removing, not inserting, the catheter into the artificial airway. If secretions are thick and difficult to remove, increasing hydration, not suctioning time, is indicated. Aerosols of sterile normal saline or mucolytics such as acetylcysteine (Mucomyst) administered by nebulizer can also be used to thin the thick secretions, but water should not be used. Aerosol therapy may induce bronchospasm in certain individuals and can be relieved by use of a bronchodilator (albuterol). (Option A) Morphine is administered to promote breathing synchrony with the mechanical ventilator, reduce anxiety, and promote comfort in clients receiving MV. (Option C) Preoxygenation with 100% oxygen for 30 seconds before suctioning, unless otherwise specified, is the recommended practice to reduce suctioning-associated risks for hypoxemia, microatelectasis, and cardiac dysrhythmias. (Option D) It is appropriate to suction the client when the high-pressure alarm on the MV sounds, saturations drop, rhonchi are auscultated, and secretions are audible or visible. These manifestations can indicate excessive secretions impairing airway patency. Educational objective: To minimize removal of oxygen and mucosal trauma, suction should be applied only when removing the catheter, not when inserting it. Other interventions to reduce the risks associated with suctioning (eg, hypoxemia, microatelectasis, cardiac dysrhythmias) include assessment for the need to suction, preoxygenating with 100% oxygen, and limiting suction time to 10-15 seconds.
