Body mechanics refers to the proper use of muscles to maintain balance, posture, and body alignment during lifting, bending, and moving patients. In busy Nigerian clinical settings, midwives frequently lift and support women during labour and postpartum recovery. Failing to use correct body mechanics leads directly to chronic lower back strain and career-ending injuries.
Positioning patients correctly is a daily duty that prevents skin breakdown, improves breathing, and promotes comfort. Midwives use specific positions depending on whether a woman is resting, recovering from a caesarean section, or undergoing a gynaecological examination.
Patients who are weak, paralysed, or recovering from major surgery cannot move themselves in bed. Frequent repositioning every two hours is mandatory to maintain skin integrity and prevent pressure ulcers.
To move a patient up in bed, first flatten the bed if the patient's condition allows, remove pillows from under the head, and ask the patient to bend their knees and push with their feet if able. Use a draw sheet with a colleague to lift and slide the patient simultaneously, reducing friction against the mattress.
When turning a patient to the side, raise the side rail on the opposite side for safety. Stand on the side you are turning the patient toward, place one hand on the shoulder and the other on the hip, and gently roll them toward you in one smooth motion. Support the back with pillows and place a pillow between the knees to prevent bony prominences from rubbing together.
Moving a patient from the bed to a chair requires careful planning and assessment of the patient's weight-bearing capability. Never guess a patient's strength; always assess their ability to follow instructions and support their own weight first.
For a pivot transfer, position the wheelchair at a 45-degree angle to the bed and lock all wheels. Ensure the patient is wearing non-slip footwear. Bring the patient to a sitting position on the edge of the bed, allowing dangling time to prevent orthostatic hypotension and dizziness. Place your hands around the patient's waist or use a transfer belt. As the patient stands, keep your knees against theirs to block buckling, pivot together, and guide them safely into the chair.
When transferring patients who have complete lower limb weakness, mechanical lifts or sliding boards are utilized to prevent injury to both the patient and the healthcare provider.
Prolonged bed rest affects nearly every body system, creating secondary medical problems that can be worse than the original illness. Midwives must actively counteract these risks through early mobilization and targeted nursing interventions.
| Body System | Complication of Immobility | Preventive Nursing Action | |
|---|---|---|---|
| --- | --- | --- | > |
| Integumentary | Pressure ulcers | Regular turning, skin hygiene, and pressure-relieving mattresses | |
| Respiratory | Atelectasis and hypostatic pneumonia | Deep breathing exercises, incentive spirometry, and frequent changes in position | |
| Cardiovascular | Deep vein thrombosis and orthostatic hypotension | Early ambulation, leg exercises, and anti-embolism stockings | |
| Musculoskeletal | Muscle atrophy and joint contractures | Passive and active range-of-motion exercises |
Documenting mobility interventions is a legal and clinical necessity in midwifery practice. Every time a patient is repositioned, transferred, or ambulated, the nurse must record the time, the specific position or transfer method used, and the patient's tolerance of the activity.
If a patient complains of chest pain, severe dizziness, or shortness of breath during a transfer or mobilization attempt, immediately halt the activity and assist them back to a safe resting position. Report unusual observations to the attending physician or senior midwife straight away. Always prioritize patient dignity by keeping the patient properly draped and covered during turns and transfers, ensuring that safety never compromises respect.
