실험적: 경막천자 경막외 그룹과 결합된 초음파 실시간 유도
초음파 실시간 유도와 경막외 경막 천자 결합 진통 진통의 임상 효과를 향상시킬 수 있습니다.
|
초음파 실시간 유도 기술은 수술 시각화를 통한 추간 공간 위치 파악의 정확도, 성공률, 천공 손상 감소 측면에서 기존의 맹인 탐사 기술에 비해 큰 장점을 갖고 있어 척추 블록의 효율성과 안전성을 크게 향상시킵니다.

활성 비교기: 경막천자 경막외 그룹
경막외 천자(Dural Puncture Epidural)는 척추-경막외 결합(Combined Spinal-Epidural)의 임상적 개선으로 산모에게 널리 사용됩니다.
시행 단계는 경막외 천자를 완료하고 일시적으로 튜브를 삽입하지 않고 지주막하 마취 바늘로 경막을 천자하되 지주막하 공간에 직접 약물을 주입하지 않고 경막외 카테터를 남겨서 경막외 차단에 따라 투여하는 것입니다. .

|
Composite endpoint of labor analgesia outcome
기간: From initiation of labor analgesia to delivery (assessed up to 24 hours).
|
The primary outcome is a binary composite endpoint: "satisfactory" (Grades I-II) versus "unsatisfactory" (Grades III-IV). Grading followed a hierarchical rule (IV > III > II > I): if more than one grade applied, the highest (worst) was assigned. Grade I (best): vaginal delivery (spontaneous or instrumental) with analgesic onset ≤ 20 min, mean VAS ≤ 40 mm, no catheter or protocol adjustment, and modified Bromage score < 2. Grade II (good): vaginal delivery not meeting Grade I criteria but with onset ≤ 30 min, mean VAS ≤ 60 mm, and no Grade IV-listed complications. Grade III (poor): cesarean delivery, or onset > 30 min, or mean VAS > 60 mm. Grade IV (worst): serious analgesia-related complications (unintended dural puncture with the epidural needle, Bromage score ≥ 2, persistent neurological injury, local anesthetic toxicity, or severe hypotension requiring intervention). |
From initiation of labor analgesia to delivery (assessed up to 24 hours).
