A tracheotomy is a surgical procedure that creates an opening into the trachea through the neck, establishing a direct airway. Nurses encounter this intervention across various units, from intensive care to specialized surgical wards in Nigerian hospitals. The primary goal is bypassing upper airway obstructions, facilitating long-term mechanical ventilation, or managing copious pulmonary secretions when endotracheal intubation is no longer safe or feasible.
Precise anatomical knowledge prevents catastrophic surgical complications like hemorrhage or tracheal wall perforation. The trachea sits anteriorly in the neck, composed of C-shaped cartilaginous rings that keep the airway patent. Surgeons typically create the stoma between the second and third tracheal rings, carefully avoiding surrounding vascular and endocrine structures.
Tracheostomy tubes vary by material, design, and presence of an inflatable cuff. Understanding these parts ensures proper patient care, cleaning, and emergency readiness.
Daily assessment of the tracheostomy site prevents local infection, skin breakdown, and tube displacement. Nurses inspect the peristomal skin for redness, maceration, or purulent drainage. Cleaning involves sterile technique using normal saline or prescribed antiseptic solutions to remove crusting without disturbing the secure placement of the tube.
Tape or Velcro ties must be secure enough to prevent accidental decannulation while allowing room for one finger to fit comfortably underneath. Changing ties requires a two-person technique on fresh stomas to prevent the tube from popping out unexpectedly.
Secretions accumulate rapidly in artificial airways because the upper airway's natural filtering and humidifying mechanisms are bypassed. Nurses perform tracheal suctioning only when clinically indicated—such as hearing coarse breath sounds, seeing mucus in the tube, or observing a drop in oxygen saturation—rather than on a rigid schedule.
Pre-oxygenation with 100% oxygen is standard practice before suctioning to prevent hypoxia. The catheter is inserted gently without suction applied until reaching the desired depth, followed by intermittent suctioning and rotation while withdrawing the catheter. Total suction time must not exceed ten to fifteen seconds to avoid severe oxygen deprivation and cardiac arrhythmias.
Emergency preparedness is mandatory for any nurse caring for a tracheostomy patient. Accidental decannulation, tube blockage from thick mucus plugs, and severe hemorrhage are life-threatening events requiring immediate, decisive action.
If a tube dislodges within the first few days post-surgery, it is a surgical emergency because the tract has not matured and can close rapidly. The nurse must call for help, attempt gentle reinsertion using an obturator, or ventilate via bag-valve-mask over the stoma if reinsertion fails. A spare tracheostomy tube of the same size and one size smaller must always be kept at the bedside.
As the underlying condition improves, patients undergo a weaning process to prepare for tube removal, known as decannulation. This involves gradually downsizing the tube or using fenestrated tubes and speaking valves to redirect airflow through the upper airway and vocal cords.
Once the patient tolerates complete tube capping for 24 to 48 hours without respiratory distress, the tube is removed. The stoma site is covered with an occlusive dressing and sterile gauze, healing by secondary intention within a few days. Patient and caregiver education focuses on recognizing signs of respiratory distress, performing stoma hygiene, and knowing when to seek emergency medical help.
