研究目的:

通过观察三组不同麻醉方式下肥胖产妇麻醉阻滞效果、新生儿出生指标、产妇术后镇痛、不良反应、运动阻滞恢复情况及术后住院时长等多方面来探究DPEA在肥胖产妇剖宫产术中的应用价值,探索出一种更适合肥胖产妇剖宫产术的麻醉方式,从而为DPEA技术安全、有效地应用于肥胖产妇剖宫产提供理论依据。  

Objectives of Study:

By observing multiple aspects such as the anesthetic block effect under three different anesthesia methods in obese parturients, neonatal birth indicators, postoperative analgesia in parturients, adverse reactions, motor block recovery, and postoperative hospitalization duration, this study aims to explore the application value of DPEA in cesarean sections for obese parturients, identify a more suitable anesthesia method for cesarean sections in obese parturients, and thus provide a theoretical basis for the safe and effective application of DPEA technology in cesarean sections for obese parturients.

EA组

Group:

EA Group

Sample size:

干预措施:

选择 L2~3间隙以16G硬膜外针行硬膜外穿刺,穿刺针刺破黄韧带感觉阻力消失,使用1ml生理盐水硬膜外阻力消失法确认穿刺成功后回抽无脑脊液即确定穿刺针进入硬膜外间隙,穿刺成功。然后向头侧硬膜外腔置入导管4cm,给予2%利多卡因4ml并观察有无异常症状,同时固定可靠后孕妇改仰卧位。观察3min后无异常则再注入0.75%罗哌卡因12ml。

干预措施代码:

Intervention:

Select the L2~3 interspace for an epidural puncture using a 16G epidural needle. When the yellow ligament is pierced, a loss of resistance is felt. After confirming successful puncture by injecting 1ml of normal saline and observing the loss of resistance, aspiration without cerebrospinal fluid confirms that the needle has entered the epidural space, indicating successful puncture. Then, a catheter is inserted 4cm cephalad into the epidural space. 4ml of 2% lidocaine is administered, and any abnormal symptoms are observed. After reliable fixation, the pregnant woman is turned to the supine position. If no abnormalities are observed after 3 minutes, 12ml of 0.75% ropivacaine is injected.

Sample size:

干预措施:

选择 L2~3间隙以16G硬膜外针行硬外穿刺,同EA组方法判断穿刺成功,再经硬膜外针置入25G腰麻针,继续进一步行硬脊膜穿刺,有穿刺突破感后,拔出腰麻针针芯,观察有脑脊液流出即确认穿破硬脊膜。拔出腰麻针,向头侧硬膜外腔置入硬膜外导管4cm ,给予2%利多卡因4ml并观察有无异常症状,同时固定可靠后孕妇改仰卧位。观察3min后无异常则再注入0.75%罗哌卡因12ml。

干预措施代码:

Intervention:

Select the L2~3 interspace and perform an epidural puncture with a 16G epidural needle. Determine the success of the puncture using the same method as the EA group. Then, insert a 25G spinal needle through the epidural needle and proceed with further dural puncture. After feeling a sense of breakthrough during puncture, remove the core of the spinal needle. The successful puncture of the dura mater is confirmed when cerebrospinal fluid flows out. Remove the spinal needle and insert an epidural catheter 4 cm into the epidural space towards the head. Administer 4 ml of 2% lidocaine and observe for any abnormal symptoms. After reliable fixation, the pregnant woman is turned to the supine position. If no abnormalities are observed after 3 minutes, inject 12 ml of 0.75% ropivacaine.

干预措施:

选择 L3~4间隙以16G硬膜外针行硬外穿刺,同EA组方法判断穿刺成功,再经硬膜外针置入25G腰麻针,继续进一步行硬脊膜穿刺,有穿刺突破感后,拔出腰麻针针芯,观察有脑脊液流出即确认穿破硬脊膜。经腰麻针注入0.5%罗哌卡因2.4ml(0.75%罗哌卡因1.6ml+10%葡萄糖0.8ml),拔出腰麻针,向头侧硬膜外腔置入硬膜外导管4cm,固定可靠后孕妇改仰卧位。

干预措施代码:

Intervention:

Select the L3~4 interspace for epidural puncture with a 16G epidural needle. Determine the success of puncture using the same method as the EA group. Then, insert a 25G spinal needle through the epidural needle, continue to perform a dural puncture. After feeling a breakthrough sensation during puncture, remove the core of the spinal needle. The successful puncture of the dura mater is confirmed when cerebrospinal fluid flows out. Inject 2.4ml of 0.5% ropivacaine (composed of 1.6ml of 0.75% ropivacaine and 0.8ml of 10% glucose) through the spinal needle. Remove the spinal needle, then insert an epidural catheter 4cm into the epidural space towards the head. After securely fixing the catheter, the pregnant woman is turned to the supine position.
