Muscles of Respiration
Refer to the Physiopedia page below for clinically relevant anatomy and how the muscles involved in breathing mechanics operate
“A break in the structural continuity of the bone” that can be caused by trauma, stress and pathological factors." (Apley, Solomon, Warwick, Nayagam & Apley, 2005)
Classification according to the nature of the fracture:
Pulmonary complications 48-72 hours after admission (Battle, Hutchings, James, & Evans, 2013):
- Pleural effusion
- Subcutaneous emphysema
- ARDS (Acute Respiratory Distress Syndrome)
- Pulmonary emboli
- Lobar collapse
Risk factors for developing associated conditions (Battle, Hutchings, James, & Evans, 2013):
- >65 years old
- >3 rib fractures
- Hx. of chronic lung conditions or CVD
- Pre-injury anti-coagulant use
- <90% SpO2
A flail segment is a portion of the rib cage that breaks due to trauma and becomes unattached from the chest wall. (Pettiford, Luketich & Landreneau, 2007). Generation of negative intrapleural pressure indicates a true paradoxical flail segment (May, Hillermann & Patil, 2015).
Radiologists use Chest X-Rays to look for the following:
“Three or more adjacent ribs are fractured in two or more places. Clinically this can be a segment of only one or two ribs can act as a flail segment” (Stanislavsky, 2018).
Physiotherapy Management / Interventions
Chest physiotherapy management consists of the following:
1. Ventilatory Management - supplemental oxygen therapy, continuous positive airway pressure or intubation if necessary (May, Hillermann & Patil, 2016)
- CPAP - for negative intrapleural pressure and paradoxical movement, increases TV (May, Hillermann & Patil, 2015)
- Open/closed suction if patient intubated (Berney, Haines & Denehy, 2012)
2. Pain Management and Education (May, Hillermann & Patil, 2016)
- Education on fracture healing
3. Early mobilization if possible (May, Hillermann & Patil, 2016)
- Transfers to sitting out of bed
- Mobilization 2-3x daily and SOOB 3-4x/day
4. Chest and airway clearance techniques (if inadequate) (May, Hillermann & Patil, 2016)
- ACT: nebulizer with ACBT and education
- Bubble PEP or Flutter
5. Deep breathing exercises and supported coughing technique (May, Hillermann & Patil, 2016)
- Supported Cough: Wrap around technique or rolled up towel
- DBE/TEE’s with SMIs (2-4 secs hold)
6. Positioning (Berney, Haines & Denehy, 2012)
- Positioning in side lying and high sitting
Medications: (May, Hillermann & Patil, 2016)
- Simple Analgesics
- Patient Controlled Analgesia
- Operative fixation and Regional Anaesthetic
Conservative (May, Hillermann & Patil, 2016)
- Regional anaesthesia
- Serratus anterior block
- Paravertebral block
- Thoracic epidural
Internal fixation (May, Hillermann & Patil, 2015)
- Decreases stay in ICU and MV duration (Leinicke et al., 2013)
- Similar to thoracotomy but incision but spares Latissimus Dorsi
- Anterior # - plates and locking screws
- Posterior # - intramedullary splints
