Epidural Computer Controlled System for the Epidural Space Verification

May 23, 2017 updated by: Giorgio Capogna, Città di Roma Hospital

Identification of the Epidural Space: a Double Blind Comparison Between th CompuFlo® Epidural Computer Controlled System and the Standard LOR to Saline Technique in Obstetrics

The purpose of this study will be to evaluate the inter-rater agreement, or concordance, between an expert anaesthesiologist and the CompuFlo® Epidural Computer Controlled System for the epidural space verification.

Primary study endpoint will be successful concordance of identification of ligamentum flavum and epidural space during a standard epidural procedure in pregnant patient. Secondary outcome will be successful concordance of identification of bony contact during a standard epidural procedure in pregnant patient.

Detailed Description

After skin local anesthesia and after the subcutaneous insertion of the epidural Tuohy needle, an independent investigator will make the O point of the CompuFlo® device that will be connected, via a three way stopcock, to the Tuohy needle in order to register, in a double blind way, the delta of pressures encountered by the needle during its advancement.

When the operator will reach the supraspinous ligament, a slight resistance will be encountered due to the nature of the bevel, and the density of the ligament. As soon as this resistance will be felt, the operator immediately will tell the investigator who will flag the CompuFlo® device. If no sensation will be felt the operator will tell "none" to the investigator.

The needle will be then advanced through the loose interspinous ligament which typically offers much less resistance than the sopraspinous ligament (often felt as a "no resistance feeling" in the obstetric patient). Once again, as soon as this loss or reduced or no resistance sensation is felt, the operator immediately will tell the investigator who will flag the CompuFlo® device. If no sensation will be felt the operator will tell "none" to the investigator.

According to the standard epidural technique, the point of the needle will be further advanced. The feeling of a greater increase of resistance, often associated with a "crunch", usually indicates the initial penetration of the needle in the rear wall of the ligamentum flavum. As soon as this resistance or "crunch" is felt, the operator immediately will tell the investigator who will flag the CompuFlo® device.

Then, the operator will remove the stylet and gently will attach to the needle a disposable 10 mL loss of resistance syringe containing a few millimeters (5-7 mL) of sterile saline solution and will open the three way stopcock in order to record both the pressures given-and-received by the CompuFlo® and the pressure produced by the operator's hand.

Constant, unremitting pressure will be now exerted on the plunger of the syringe by the thumb of the dominant hand of the operator in order to obtain the needle advancement solely by means of the pressure exerted by the operator on the plunger of the syringe.

As the point of the needle will emerge from the ligamentum flavum into the epidural space, the resistance suddenly will disappear and the advancement of the needle immediately will stop, (since the driving force exerted on the piston is discharged by the sudden entering of the liquid in the epidural space). As soon as this loss of resistance is felt, the operator immediately will tell the investigator who will who will flag the CompuFlo® device. The operator will stop the procedure for at least 10 seconds to allow the investigator to record the static epidural pressures.

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.

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
anesthesiologist
The active comparators for this study will be expert anaesthesiologists (operator). The operators will be blinded to all visual and audible CompuFlo® real-time pressure feedbacks.Inter-rater agreement, or concordance, between an expert anaesthesiologist and the CompuFlo® Epidural Computer Controlled System for the epidural space verification will be assessed by blinded tagging of the operator's feeling of the ligamenta and epidural space on the screen of the Compuflo to be eventually compared with the pressure's variations

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.

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.
