Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Tracheostomy Suctioning II: Procedure

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Suctioning the Oropharyngeal Airway

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Area of Science:

Neurology
Rehabilitation Engineering
Biomedical Devices

Background:

Stroke commonly causes upper extremity paralysis, impacting daily living activities.
Advanced technologies, including wearable devices, are crucial for post-stroke hand function recovery.
Improving grasping ability is a key goal in stroke rehabilitation.

Purpose of the Study:

To develop and evaluate a novel hybrid rehabilitation functional assist device for post-stroke patients.
To enhance hand grip strength and functional ability in daily grasping tasks.
To assess the device's efficacy using standardized clinical assessments.

Main Methods:

Developed a rehabilitation device integrating flexion/extension mechanisms with suction cup technology.
Recruited ten post-stroke hemiplegia patients for a functional assessment study.
Validated outcomes using the Toronto Rehabilitation Institute - Hand Functional Test (TRI-HFT), Chedoke Arm Hand Activity Inventory (CAHAI-9), and Fugl-Meyer Assessment (FMA).

Main Results:

Significant improvements observed across all three clinical tests (TRI-HFT, CAHAI-9, FMA) with p-values < 0.05.
Mean scores increased substantially: TRI-HFT (14.5 to 25), CAHAI-9 (5.4 to 10), FMA (9.6 to 17).
Participants reported an average feedback score of 3.8/5, noting ability to perform tasks previously impossible without the device.

Conclusions:

The hybrid rehabilitation device significantly enhances impaired hand functionality in post-stroke patients.
The technology offers a promising solution for improving grasping capabilities and independence in daily activities.
The device demonstrated clinical effectiveness and positive user feedback, supporting its role in stroke rehabilitation.
