简要总结
Ultrasound is widely in uses for vascular, nerve block and sometimes neuraxial block. The purpose of the study is to evaluate the impact of a handheld ultrasound device on the time to complete labor epidural placement and success rate of epidural analgesia in parturients with a wide range of body mass indexes (BMIs).
A handheld ultrasound device (Accuro, Rhivanna Medical, Charlottesville, VA) may eliminate the time for equipment setup due to its portability and instant power-up. In addition, it provides a simulated diagram to aid in identifying bone and lumbar spaces. These unique features may be helpful in laboring women with a particular BMI range. We aim to define the usefulness of guidance with a handheld ultrasound in completing labor epidural analgesia in various BMIs.
The primary outcome: The time needed to complete epidural placements.
Secondary outcomes:
- The number of needle insertion attempts,
- The rate of success measured by the need to replacements during the labor course for vaginal or cesarean delivery.
详细描述
This randomized prospective clinical trial aims to evaluate timing savings in performing labor epidural analgesia and the success rate of labor analgesia with and without the guidance of a handheld ultrasound device in various BMI groups.
In routine clinical setting, patients admitted to clinic and evaluated labor condition. If patient in active labor and request epidural for labor pain, the standard care team inform obstetric anesthesia epidural team by using pager. Standard of care anesthesia epidural team perform preoperative evaluation and placed the catheter.
The patients in active labor will receive labor epidural analgesia, regardless of the study participation. There is no changes epidural local anesthetic type and doses. The research intervention is only placing hand-hold ultrasound to the back of the patient and see the land mark visually before the epidural catheter placement. The remaining catheter placement is the same as the control group.
Study Procedures:
A Total of 300 eligible parturients will be randomly assigned to one of the two groups either the ultrasound imaging guidance or the traditional landmark palpation group for labor epidural needle placement. The research intervention is simply placing a hand-held ultrasound device on the back of the patient and insert the epidural needle with ultrasound image guidance.
