Level of consciousness reflects a patient's responsiveness to the environment. When consciousness is lost, the brainstem and cerebral hemispheres are severely impaired by trauma, infection, stroke, or metabolic derangements. Midwives caring for obstetric and gynecological patients must recognize early signs of neurological decline, such as severe eclamptic coma or septic shock leading to cerebral hypoperfusion.
The Glasgow Coma Scale (GCS) is the standard clinical tool used to assess neurological status objectively. It measures three distinct responses:
A total score of 15 indicates a fully alert patient, while a score of 8 or less typically indicates a severe coma requiring immediate airway protection. Always record the individual sub-scores alongside the total (e.g., E4V5M6) to communicate specific changes clearly to the medical team.
An unconscious patient loses muscle tone throughout the body, including the pharyngeal muscles. This causes the tongue to fall backward against the posterior pharynx, obstructing the airway. In the emergency or ward setting, securing airway patency takes absolute precedence over all other interventions.
Positioning is the first line of defense. Place the patient in a lateral recovery position if spinal injury is ruled out, as this allows secretions, blood, or vomitus to drain freely out of the mouth rather than pooling in the trachea. Suctioning equipment must be readily available at the bedside to clear the oral cavity, but suctioning should be brief—lasting no longer than 10 to 15 seconds—to prevent severe hypoxia.
Administer supplemental oxygen via face mask or nasal cannula to maintain adequate oxygen saturation above 94%. If the patient has absent gag reflexes or a GCS of 8 or below, prepare for emergency endotracheal intubation by the anaesthetist or doctor.
Once the airway is secured, stabilizing the circulation ensures adequate cerebral and systemic perfusion. Monitor blood pressure, pulse rate, and oxygen saturation continuously or at least every thirty minutes depending on stability. Hypotension starves the already vulnerable brain of oxygen, deepening ischemic injury.
Neurological monitoring must be performed alongside vital signs. Assess pupil size, symmetry, and light reflex. Pinpoint pupils can indicate opioid overdose or pontine damage, while unilateral fixed and dilated pupils suggest dangerous intracranial pressure herniating the brainstem. Check for symmetrical limb movements or respond to painful stimuli systematically, noting any asymmetry that points to a focal brain lesion.
Immobile unconscious patients cannot shift their weight or report discomfort, making them prime targets for pressure injuries. Sustained pressure over bony prominences—such as the sacrum, heels, elbows, and occiput—restricts capillary blood flow, leading to tissue ischemia and necrosis.
Implement a strict two-hourly turning schedule, alternating between the back and each side, using pillows to keep bony surfaces from touching. Keep bed linens clean, dry, and free of wrinkles that can cause friction. Apply barrier creams to skin exposed to incontinence, and use pressure-relieving mattresses where available. Inspect the skin during every turn to catch early signs of redness or blanching failure.
An unconscious patient cannot take oral food or fluids, placing them at high risk of malnutrition and dehydration. Intravenous fluids are initiated initially to maintain electrolyte balance and hydration. For longer periods of unconsciousness, enteral nutrition via a nasogastric tube is established to preserve gut mucosal integrity and prevent bacterial translocation.
Elimination requires careful management. Urinary incontinence or retention is common; therefore, an indwelling urinary catheter is often inserted to monitor exact fluid balance hourly and keep the skin dry. Strict aseptic technique during catheter care prevents urinary tract infections. Bowel function must also be monitored, as immobility frequently causes constipation or fecal impaction. Administer prescribed suppositories or enemas and document all bowel movements.
Protective reflexes, including the blink reflex and tear production, are often lost or diminished in unconscious patients. Without these mechanisms, the cornea dries out, leading to exposure keratitis, ulceration, and potential permanent vision loss.
Midwives must perform specialized eye care every four to six hours. Gently clean the eyelids with sterile normal saline, wiping from the inner canthus outward. Apply prescribed lubricating eye drops or ointment, and tape the eyelids shut if natural closure is absent.
Comprehensive hygiene also includes daily bed baths, oral care to remove dried secretions and prevent ventilator-associated pneumonia, and meticulous perineal care after every episode of incontinence.
Prolonged bed rest affects every body system. In the respiratory system, pooling secretions lead to atelectasis and hypostatic pneumonia. Combat this by performing chest physiotherapy, postural drainage, and regular suctioning.
In the musculoskeletal system, lack of movement causes muscle atrophy and contractures, where joints stiffen in fixed positions. Perform passive range-of-motion exercises twice daily for all major joints. Apply anti-embolism stockings or sequential compression devices to reduce venous stasis and prevent deep vein thrombosis, which can lead to fatal pulmonary embolism.
An unconscious patient is cut off from communication, but hearing is often the last sense to be lost. Midwives should encourage family members to talk, read, and touch the patient gently. Always explain every nursing procedure out loud before performing it, even if the patient appears completely unresponsive.
Families experiencing the sudden unconsciousness of a loved one face intense shock, grief, and anxiety. Offer clear, compassionate updates without giving false hope. Invite them to participate in simple care activities, such as hand massage or applying lotion, which helps reduce their feelings of helplessness and fosters a trusting nurse-family relationship.
