Combined Plexus Block for Hip Fracture Surgery.

July 17, 2018 updated by: University Hospital, Montpellier

Is the Combined Plexus Block a Real Alternative for Hip Fracture Surgery in the Elderly? A Comparison With General Anesthesia and Continuous Spinal Anesthesia Using a Propensity Score in a Retrospective Cohort Study.

Hip fracture surgery requires high risk anesthetic procedure for elderly patients (1). General anesthesia, continuous spinal anesthesia and peripheral nerve blocks are three anesthetic techniques possible. Continuous spinal anesthesia has proven its efficacity to provide an intraoperative haemodynamic stability wich guarantees good patients outcomes (2), in comparison with general anesthesia but there is poor evidence in the literature concerning the use of peripheral nerve blocks.

The primary objective of this study was to compare intraoperative haemodynamic stability provides by peripheral nerve block versus general anesthesia and continuous spinal anesthesia.

Secondary outcomes included : use of vasoactive drugs, opioids consumption, lengh of stay and inhospital mortality.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

After receiving the ethic approval from the "CERAR", the investigators retrospectively identified all patients who underwent hip fracture surgery from January 1 2015, to December 31, 2016 in the CHU of Montpellier. The exclusion criteria were: multiple trauma victims, two hip fractures in the same patient and single shot spinal anesthesia. In our institution the investigators used to perform three types of anesthesia: general anesthesia (GA), continuous spinal anesthesia (CSA) and combined plexus blocks (CPB). The investigators therefore made three groups GA, CSA and CPB and used a propensity score to make these groups comparable. The matching criteria were age, arterial hypertension, ASA status, Frailty score, chronic cardiac failure and type of surgery.

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.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
593

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
Measure Description
Time Frame
Intraoperative hypotension
Time Frame: 1 day
Decrease of at least 30% of mean arterial pressure
1 day

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
measure the total consumption of the vasopressive molecules
Time Frame: 1 day
measure the total consumption of the vasopressive molecules (necessary when the voltage drops by more than 30% compared to the average reference voltage) : Use of vasoactive drugs
1 day
Length of stay
Time Frame: 1 day
Length of stay
1 day
compare the use of emergency antalgics
Time Frame: 1 day
compare the use of emergency antalgics : opioids consumption
1 day
Inhospital mortality
Time Frame: 1 day
Inhospital mortality
1 day

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.
