Study: Manometry With & Without Lidocaine

October 1, 2019 updated by: University of Wisconsin, Madison

The Effect of Lidocaine on Perceived Comfort and Swallowing Pressures During High Resolution Pharyngeal Manometry

The purpose of this study is to determine whether subjects report a difference in comfort with High Resolution Pharyngeal Manometry (HRPM) conducted following application of lidocaine as an anesthetic as compared to HRPM conducted without anesthetic.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

High resolution pharyngeal manometry (HRPM) is used for assessing swallowing pressure along the length of the pharynx and upper esophageal sphincter. Pressure measurements in the region of the velopharynx, tongue base, and upper esophageal sphincter are obtained by passing a catheter with pressure sensors through the patient's nose and past the upper esophageal sphincter. Patients are presented various volumes of liquid to swallow and potentially asked to perform postural strategies such as a head turn or chin tuck during swallowing while the catheter is in place. Clinically, approximately 90% of patients report various discomfort associated with the procedure. Discomfort can result in patient refusal to participate or an inaccurate picture of a patient's swallowing pressures. Conversely, use of anesthesia can potentially alter swallowing physiology.

Recent studies have studied the effects of lidocaine on penetration/aspiration and subject discomfort during flexible endoscopic evaluations, yet findings are inconclusive or contradictive. Investigators aim to determine whether subjects report a difference in comfort with HRPM conducted following application of lidocaine as an anesthetic as compared to HRPM conducted without anesthetic.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Anesthetized
A study team member will apply 1 mL of 2% viscous lidocaine to each nares prior to the passage of the catheter, Participants in this group will additionally receive .8 mL of a 4% Lidocaine spray to both nares prior to HRPM.
Behavioral: 4% Lidocaine Spray
2% Viscous Lidocaine is applied to the nares as standard of care. In this intervention, 4% lidocaine spray is applied additionally.
Behavioral: 2% Viscous Lidocaine
2% Viscous Lidocaine is applied to the nares as standard of care. This intervention is considered as the control group.
Placebo Comparator: Non-Anesthetized
A study team member will apply 1 mL of 2% viscous lidocaine to each nares prior to the passage of the catheter. Randomized participants in this group will not receive .8 mL of a 4% Lidocaine spray prior to HRPM .
Behavioral: 2% Viscous Lidocaine
2% Viscous Lidocaine is applied to the nares as standard of care. This intervention is considered as the control group.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
A quantifiable difference of perceived comfort reduction during HRPM with or without lidocaine as assessed through analysis of a visual analog scale.
Time Frame: Assessing the change of the visual analog scale between two procedural study visits. Data will be reported at study completion, an average of 1 year.
Following HRPM without additional lidocaine and following HRPM with additional lidocaine, the subject will be asked to rate their level of comfort during the procedure using a visual analog scale.
Assessing the change of the visual analog scale between two procedural study visits. Data will be reported at study completion, an average of 1 year.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
