Pre-Insertion Ultrasound for Lateral-Position Spinal in Cesarean Delivery

Status Recruiting

Clinical Trial Summary

The purpose of this study is to evaluate the impact of lumbar ultrasound anatomic mapping using the Accuro device on the number of needle redirections, when performing spinal anesthesia in the lateral decubitus position on patients undergoing elective cesarean delivery.

Clinical Trial Description

Training in neuraxial placement most commonly occurs with patients in the sitting position, since it is easy to master. However lateral placement may be preferred in emergent situations and for patient comfort. In order to provide safe and effective anesthesia to parturients, providers must be competent with the technique in both sitting and lateral positions. Ultrasound examination prior to spinal placement is a safe, non-invasive method of determining depth, midline, and interspinous location. Its use may decrease the number of needle insertions and needle passes in parturients in the sitting position, however little is known about the benefit of ultrasound use in the placement of lateral spinals. The use of lumbar ultrasound with Accuro may improve success rates, safety, and the education of residents as they learn neuraxial placement in the lateral position. This will be the first study to examine the use of Accuro for lateral neuraxial placement. The study investigators hypothesize that lumbar ultrasound with the handheld Accuro device by an experienced provider prior to spinal insertion will result in fewer needle redirections compared to palpation of landmarks when performed by anesthesia residents or fellows. The two arms of the study are as follows: Group 1: Control Group: sham pre-puncture ultrasound procedure with the handheld Accuro device turned off, followed by a sham marking on the participant's back using the Accuro locator marker attached to the device. Group 2: Ultrasound Group: pre-puncture ultrasound with Accuro followed by marking placed at the L3-4 interspace in the midline using the attached Accuro locator marker. All ultrasound exams will be performed by an unblinded physician study investigator. All study participants will have a spinal anesthetic in lateral position performed by one of the residents or fellows participating in the study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
