Labor Analgesia Clinical Trial
Official title:
Handheld Ultrasound-assisted Versus Palpation-guided Labor Combined Spinal-epidural Analgesia: a Randomized Controlled Trial
Parturients who need combined spinal-epidural analgesia for labour analgesia are randomly assigned to two groups. For the handheld ultrasound-assisted technique group, ultrasound with 3D navigation function is used to determine the needle insertion point and the insertion angle. For the conventional palpation-guided technique group, the interspinous space is detected by palpation. Procedure time, the number of needle passes, the number of needle insertion attempts, success rate, and complications are compared.
This study aims to determine whether handheld ultrasound-guidance can reduce procedural time for labor combined spinal-epidural analgesia compared with conventional surface landmark-guided technique. ;
