Post-cardiac Surgery
Conditions
Brief summary
This study will be conducted to investigate the effect of neuromuscular electrical stimulation on phrenic regeneration post cardiac surgery
Detailed description
Phrenic nerve injury post cardiac surgery is a serious problem closely related to frequent respiratory complications. It has been associated with diaphragm dysfunction, pneumonia and difficulty weaning from mechanical ventilation in critical ill patients. Neuromuscular electrical stimulation (NMES) is commonly used in physical therapy to increase muscle strength and promote muscle hypertrophy. There is increased flow of patients after heart surgery in kasr Aini hospital who suffers from respiratory complication due to phrenic nerve injury so the hospitalization period of them increased which make economic burden in health insurance services with decreased level of quality of life that is the most concern as to improve patient status and relief this burden. So this study aims to decrease respiratory complication and improve phrenic nerve regeneration by using neuromuscular electrical stimulation as a safe, noninvasive , inexpensive and virtually risk free method.
Interventions
DEVICETranscutaneous electrical diaphragmatic stimulation intervention
It will be applied on diaphragm, 30 min per session ,3 days/week for 4 weeks at a stimulation frequency of 30 Hz, pulse width of 400 μs, the intensity was gradually increased until visible muscle contraction was observed.
The participants will receive traditional physiotherapy ( postural drainage, percussion , diaphragmatic breathing, phase 1 cardiac Rehabilitation and balance training ) three times per week for 4 weeks

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Phrenic nerve conduction study: motor latency | 4 weeks | Nihon Kohden Neuropak M1 MEB-9200 EMG machine, made in Japan will be used to measure phrenic nerve conduction study. Motor latency is the impulse traveled from the stimulation site to the recording site is called latency and it is measured in milliseconds (ms). its normal value: (5.74ms -7.10 ms). |
| Phrenic nerve conduction study: Amplitude | 4 weeks | Nihon Kohden Neuropak M1 MEB-9200 EMG machine, made in Japan will be used to measure phrenic nerve conduction study. Amplitude represents the maximal action potential depolarization and voltage gradient for all depolarized fibers of the phrenic nerve. it is measured in microvolt or millivolt (mv). its normal value: (0.47 mv-0.83 mv). |
