Dysphagia, Endotracheal Intubation, Intake Status, Swallowing Status
Conditions
Brief summary
This pre-and post-intervention study enrolled adult Intensive Care Unit(ICU) patients (≥50 years) successfully extubated after ≥48 hours endotracheal intubation and without preexisting neuromuscular disease or swallowing dysfunction. All participants received by a trained nurse-administered, hospital-based (up to 14 days) Swallowing and Oral Care(SOC) intervention comprising toothbrushing/salivary gland massage, oral motor exercise, and advice on safe-swallowing strategies. All participants' daily intake status (21 days) and oral health status, oral sensation(stereognosis, light touch and two-point discrimination), tongue and lip strength, salivary secretion, body weight) were assessed at 2, 7, 14 days post-extubation by a blinded research nurse. Feasibility was evaluated as time spent providing SOC, patients adherence to SOC components, and adverse event(i.e., coughing, wet voice, or decreased oxygen saturation) during SOC intervention.
Detailed description
With rapid growth of medical technology, patients receiving oral endotracheal intubation have increased. Although endotracheal intubation is a life-sustaining procedure, its presence can deteriorate the structure and function of oropharynx, which may contribute to the difficulties in swallowing and subsequent oral intake. Estimated 62% of patients who had been intubated ≥48 hours will experience post-extubation dysphagia. Clearly, intervention is needed but studies are lacking in this regard. Thus, the objective of this pilot trial is to evaluate effects of an Oral Swallowing Care Program on swallowing and oral intake status in patients following prolonged endotracheal intubation. This study employs a pre-and post-intervention design. The investigators were enrolled 63 post-extubated adult patients (50 years old and older) who had prolonged (≥48 hours) oral endotracheal intubation from six medical intensive care units at a medical center in Taipei, Taiwan. Participants were assessed within 48 hours post-extubation for the baseline data, then a 14-day, daily Swallowing and Oral Care (SOC) Program involves toothbrushing/salivary gland massage, oral exercise(i.e., active/resistive range-of-motion\[ROM\] exercises for tongue, lips, and jaw), and advice on safe-swallowing strategies. Outcome were assessed on 2nd, 7th, 14th, and 21st day post-extubation including oral health status, oral sensation (stereognosis, light touch and two-point discrimination), tongue and lip strength, salivary secretion, body weight. In addition, Three-Step Swallowing Screen (3-SSS) and Functional Oral Intake Scale(FOIS) were assessed daily. The data were analyzed by SPSS 12 software package.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Days to reach Oral intake status level 6 | 21 days post-extubation | Using the Functional Oral Intake Scale (FOIS), a validated tool with established validity (81%-98%) and inter-rater reliabilities (0.86 to 0.91). The scale ranges from levels 1 to 7, level 1=Nothing by mouth; level 2=Tube dependent with minimal attempts of food or liquid; level 3=Tube dependent with consistent oral intake of food or liquid; level 4=Total oral diet of a single consistency; level 5=Total oral diet with multiple consistencies, but requiring special preparation or compensations; level 6=Total oral diet with multiple consistencies with special preparation, but with specific food limitations; level 7=Total oral diet with no restrictions. |

The scale ranges from levels 1 to 7, level 1=Nothing by mouth; level 2=Tube dependent with minimal attempts of food or liquid; level 3=Tube dependent with consistent oral intake of food or liquid; level 4=Total oral diet of a single consistency; level 5=Total oral diet with multiple consistencies, but requiring special preparation or compensations; level 6=Total oral diet with multiple consistencies with special preparation, but with specific food limitations; level 7=Total oral diet with no restrictions. |
| pass or fail Three-Step Swallowing Screen at 7th day post-extubation | on 7th day post-extubation | Evaluation by using Three-Step Swallowing Screen(3-SSS). Participants were first assessed for prior history of dysphagia/feeding-tube dependence and signs of consciousness change, poor oxygen saturation (i.e., SaO2\<90%; oxygen-mask dependence; reintubation), obvious drooling, or frequent choking on saliva. If negative, participants were then asked to swallow 3mL of water. If laryngeal elevation was identified with no signs of choking or wet voice, participants were asked to swallow 50mL of water; those without any signs of choking, wet voice, or slow swallowing were considered to pass the 3-SSS. |

Participants were first assessed for prior history of dysphagia/feeding-tube dependence and signs of consciousness change, poor oxygen saturation (i.e., SaO2\<90%; oxygen-mask dependence; reintubation), obvious drooling, or frequent choking on saliva. If negative, participants were then asked to swallow 3mL of water. If laryngeal elevation was identified with no signs of choking or wet voice, participants were asked to swallow 50mL of water; those without any signs of choking, wet voice, or slow swallowing were considered to pass the 3-SSS. |

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Salivary secretion | on the 2nd, 7th, and 14th day post-extubation | Record salivary secretion using Modified Schirmer's test. With participants sitting upright, research nurses held a standardized 1-cm wide by 17-cm long Schirmer tear test strip vertically, with the rounded end of the strip placed at the floor of their mouth. At the end of 5 minutes, a wetting length in centimeter (cm) was recorded. |
| Oral health status | on the 2nd, 7th and 14th day post-extubation | The oral health status evaluated by Oral Assessment Guide(OAG), a validated tool with established validity and inter-rater reliabilities. The scores was coded as 1=no change, 2=moderate change, 3= severe change of eight categories (voice, ability to swallow, lips, saliva, tongue, mucous membrane, gingiva, teeth). All scores are summed, ranges from 3 to 24. |
| Body weight | on the 2nd, 7th, 14th and 21th day post-extubation. | Body weight |
| Oral stereognosis | on the 2nd, 7th and 14th day post-extubation | Oral stereognosis was measured by a set of five standardized researcher-made acrylic resin shapes (round, square, star, oval, and triangular), as suggested. Participants were given 30 s to visually inspect the test pieces along with the diagram of corresponding shapes before testing began.The variable are depicted in term of percentage of participants answered correct shape of each test piece (ranges 0\ 100%). |
| Oral light-touch sensation | on the 2nd, 7th and 14th day post-extubation | Oral light touch sensation was measured with Semmes-Weinstein monofilaments. A standardized set of 5 monofilaments with values from 1.65 to 3.22 (log force) was used. |
| Oral two-point discrimination | on the 2nd, 7th and 14th day post-extubation | The stereognostic ability of the tongue was tested using the MacKinnon-Dellon Disk-criminator. The variable are depicted in term of distance in millimeter (mm) when two-point sensation was perceived by participants. |
| Tongue and lip strength | on the 2nd, 7th, and 14th day post-extubation | The tongue and lip strength assessed using the Iowa Oral Performance Instrument (IOPI System; IOPI Medical LLC, Carnation, WA, USA). |
