| Objective:To compare the consistency of pre-opertive palpation and postoperative supersound on epidural analgesia interval to caesarean preg-nant wome.Methods:Sixty ASAâ… orâ…¡patients undergoing elective caesarean surgery performed under epidural analgesia. All patient muscle inject luminal 0.1, Atropine 0.5mg. Routine monitoring ECG,SPO2,non-invasive blood pressure after enter operation room. Open periphery veins, sequentia swing pricking punct position,roution cleanse, pave asepsis hole scarf, prick expel layer infiltrate in intradermally,subcutaneouly, interspinal ligaments with 1% lidocaina.Select prick, Epidural transfixion pin porck local anesthesia pinpoint insertion. Thought force of resistance to vanish,definite into epidural interspace,postop today or the first day ascertainment lumbar intervertebral space use ultrasoundResults:Obese pregnant women ultrasound to determine to determine the epidural space and positioning preoperation were significantly different the same rate of 70-74%.It is different one or two space between ultrasound cocalization and palpation by clinicians.Conclution:Epidural puncture, palpation positioning with large errors, the preliminary the preliminary verification by ultrassound error rate of 26-30%. |
