A Comparison of Two Pain Control Techniques on Deliruim in Hip Fracture Patients

April 19, 2022 updated by: Leslie Thomas

Does Femoral Nerve Catheterization Reduce the Incidence of Post-Operative Delirium in Patients Presenting for Hip Fracture Repair?

The purpose of this study is compare the rates of post-operative delirium between a group of people receiving intravenous (IV) pain control after hip fracture surgery and a group of people receiving a femoral nerve catheter for pain control. Post-operative delirium is confusion that can happen after the deep sleep of anesthesia. AThe hypothesis is that the group receiving the femoral nerve catheter for pain may have a lower incidence of delirium than the group receiveing IV pain medication.

Study Overview

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

Subjects will have their hearing and vision tested. They will have their ability to think and analyze information tested using 4 questionnaires/ surveys: The Confusion Assesment Method (CAM), the Mini-Mental Status Examination (MMSE), Modified Blessed Dementia scale (MBDS), and Barthel's Activities of Daily Living (ADL). They will have pain medication prior to surgery based on the doctor's orders.

On the day of surgery, subjects will be randomized (like a flip of a coin) into one of two groups. One group will receive IV medication to control for pain after surgery. The other group will receive a femoral nerve catheter to control for pain after surgery.

A femoral nerve catheter is the small tubing that delivers numbing medicine to the nerves around the hips that control pain. This will be placed either before, during or soon after your surgery to help with pain after the surgery. This catheter is placed using an ultrasound machine. Subjects will still have pain medication through the IV before surgery if the catheter is put into their leg.

After surgery, you will be given the pain medication either through the IV or through the catheter in your leg. The catheter will be left in after surgery for 2-3 days delivering numbing medicine to the nerves. If subjects have the catheter in their leg and need more pain medication, the medication will be given to them through the IV.

Subjects will be visited by a member of the study staff on the second and third day after surgery. The study staff member will ask questions about the subject's ability to think and analyze information.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

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
Time Frame
number of participants developing delirium post-operatively
Time Frame: 3 days post-operatively
3 days post-operatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
the number of days admitted to the hospital post-operatively
Time Frame: participants will be followed for the duration of the hospital stay, an expected average of 4 days
participants will be followed for the duration of the hospital stay, an expected average of 4 days
Is there a difference in pain scores between subjects receiving the femoral nerve catheter vs. opioid only therapy for hip fracture pain using the visual analog scale (VAS) and consumption of pain medication for breakthrough pain relief?
Time Frame: post-op day 2 and again on post-op day 3
Two VAS scores, at least 6 hours apart, will be taken from the medical chart on post-op day 2 and again on post-op day 3. The amount of pain medication (opioids), such as morphine, hydrocodone, oxycodone, etc. consumed will be recorded until discharge.
post-op day 2 and again on post-op day 3
