Complications of Cough

2. Functions of Cough
1) Airway clearance
2) Protecting the lung from retaining inhaled particles
and irritants such as the aspiration of upper airway
and gastrointestinal secretions
3) Preventing atelectasis as might occur after
intubation, general anesthesia and surgery
4) Highly effective in cardiopulmonary resuscitation,
Vigorous coughing can elevate systolic blood
pressures to near 140 mm Hg, compared to systolic
pressures of about 75 mm Hg generated with well
performed chest compressions

3. Mechanism of Cough

5. Acute,
Subacute &
Chronic

6. Diseases & Characteristics

11. Complications of Cough
 Cardiovascular
 Respiratory
 Gastrointestinal & Genitourinary
 Musculoskeletal
 Neurological

12. Cardiovascular
Arterial hypotension
Brady- & tachy-arrhythmias
Dislodgement/malfunctioning of intravascular
catheters
Syncope
Rupture of subconjunctival, nasal, and anal veins and
massive intraocular suprachoroidal hemorrhage
during pars plana.

13. Respiratory
Exacerbation of asthma
Herniations of the lung (eg, intercostal & supraclavicular)
Hydrothorax in peritoneal dialysis
Laryngeal trauma (eg, laryngeal edema & hoarseness)
Pulmonary interstitial emphysema, with potential risk of
pneumatosis intestinalis, pneumomediastinum,
pneumoperitoneum, pneumoretroperitoneum,
pneumothorax, subcutaneous emphysema
Tracheobronchial trauma (eg, bronchitis and bronchial
rupture)

14. Gastrointestinal & Genitourinary
Gastroesophageal reflux events
Gastric hemorrhage following percutaneous endoscopic
gastrostomy
Hepatic cyst rupture
Herniations (eg, inguinal, through abdominal wall, small
bowel through laparoscopic trocar site)
Malfunction of gastrostomy button
Mallory-Weiss tear
Splenic rupture
Inversion of bladder through urethra
Urinary incontinence

15. Neurological
Acute cervical radiculopathy
Cerebral air embolism
Cerebral spinal fluid rhinorrhea
Cervical epidural hematoma associated with oral
anticoagulation
Cough syncope
Dizziness
Headache
Malfunctioning ventriculoatrial shunts
Seizures
Stroke due to vertebral artery dissection71

16. Musculoskeletal
From asymptomatic elevations of serum creatine
phosphokinase to rupture of rectus abdominus
muscles
Diaphragmatic rupture
Rib fractures
Sternal wound dehiscence

17.  Constitutional symptoms : Excessive sweating,
anorexia, exhaustion.
 Psychosocial: Fear of serious disease, Lifestyle changes,
Self-consciousness.
 Quality of life: Decreased.
