Randomized Controlled Study on T-PEP Versus IPV Method for Lower Respiratory Airways Clearance in Tetraplegic Tracheotomized Spinal Cord Injured Patients

2019-11-03 15:11:01 | BioPortfolio

Summary

In tetraplegic patients with complete cervical spinal cord injury, respiratory complications are very frequent, especially in the sub-acute phase: the lungs often become obstructed due to the accumulation of secretions and the contemporary inefficiency of the cough mechanism. The present pilot study aims, in the context of a rehabilitative Critical Care Unit, at evaluating a not yet published method, called "T-PEP" and based on the principle of Positive Expiratory Pressure, applicable to tracheotomised and mechanically ventilated patients. This method, conceptually simple and low cost, is compared with a known method based on the principle of Percussive Intrapulmonary Ventilation (IPV). Safety and efficacy issues are covered.

Description

Respiratory complications are very frequent, especially in the sub-acute phase following a spinal cord injury and must be treated to avoid even very serious outcomes. In the patient with a complete cervical spinal cord injury (and therefore tetraplegic, from a motor perspective), the lungs often become obstructed due to the accumulation of secretions and the contemporary inefficiency of the physiological mechanism of the cough. Various methods for bronchial clearance are known, but when the patient is tracheotomized and the secretions accumulate in the deepest part of the lung, nowadays the only described method available to mobilize such secretions and allow more efficient respiratory exchanges is based on the principle of Percussive Intrapulmonary Ventilation (IPV). It requires a special device, equipped with a pneumatic air generator, connected to the tracheal cannula. Such treatment needs the assistance of highly trained and expert operators, moreover IPV is a quite complex and expensive technique which has to be applied in a prudential manner in such tetraplegic patients, especially because they show significant hemodynamic instability in the acute/sub-acute phase after the spinal cord lesion.

The principle of Positive Expiratory Pressure (PEP) is already known for its efficacy in the secretions' clearance of the lower respiratory airways in other pathological conditions. However, in its classic modalities, it requires the preservation of the functionality of the respiratory muscles. To circumvent this limit in tetraplegic and tracheotomized patients, a respiratory physiotherapeutic procedure called "T-PEP" has been developed at the Montecatone Rehabilitation Institute. Such method is conceptually simple and low cost, it requires the manual assistance of a trained physiotherapist and the use of some components of common use in the clinical practice of Critical Care Units.

The present pilot randomized controlled trial aims at comparing the T-PEP and IPV methods, assigned to 2 parallel arms (1:1 allocation ratio), in the context of the Critical Care Unit of the Montecatone Rehabilitation Institute hospital, in sub-acute, tetraplegic, tracheotomized, mechanically ventilated, spinal cord injured patients. The trial covers safety and efficacy issues; cognitive performances are also addressed.

Medical and Biotech [MESH] Definitions

A syndrome associated with traumatic injury to the cervical or upper thoracic regions of the spinal cord characterized by weakness in the arms with relative sparing of the legs and variable sensory loss. This condition is associated with ischemia, hemorrhage, or necrosis involving the central portions of the spinal cord. Corticospinal fibers destined for the legs are spared due to their more external location in the spinal cord. This clinical pattern may emerge during recovery from spinal shock. Deficits may be transient or permanent.

Repair of the damaged neuron function after SPINAL CORD INJURY or SPINAL CORD DISEASES.

A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.

The segment of the spinal cord within the CERVICAL VERTEBRAE.

Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop. (From Adams et al., Principles of Neurology, 6th ed, p1269)
