简要总结
Interventional study that evaluate analgesia and side effects of Ultrasound guided Caudal block preoperatively in benign canal anal surgery
详细描述
Postoperative pain is an important symptom in patients after benign anal canal surgery. Caudal block has been described to decrease postoperative pain in this type of surgery. Ultrasound is a tool that facilitates its performance and increases the rate of a successful block.
Objective
To determine the usefulness of ultrasound guided caudal block in anesthesia and postoperative analgesia in patients scheduled for benign anal surgery. Methods : Interventional study in adult patients that received ultrasound caudal anesthetic block before benign anal surgery. The investigators evaluated analgesic efficacy of this intervention by mean of numeric rating scale ( NRS) for pain after 6, 12 and 24 hours of surgery, rescue analgesia, motor block, urinary retention, surgical conditions and patient satisfaction in postoperative period.

研究组 & 干预措施
Ultrasound Guided Caudal Block
30 minutes before benign canal anal surgery, a 18 G tuohy needle guided with an ultrasound probe to visualize the caudal space, a solution of bupivacaine 0.25%, Lidocaine 1% and dexamethasone 8mg was injected and needle removed.
干预措施: Ultrasound Guided Caudal Block (Procedure)
结局指标
主要结局
postoperative pain intensity (P3). Self reported pain intensity at 6, 12 and 24 hours after surgery.
时间窗: 1 day
The pain numeric Rating Scale (NRS) is a single 11-point numeric scale in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of their pain , with 0 representing one pain extreme (e.g., "no pain") and 10 representing the other pain extreme (e.g., "pain as bad as you can imagine" and "worst pain imaginable")
次要结局
- Rescue Analgesia (R3) need of opioid medication for rescue severe postoperative pain at 6, 12 and 24 hours after surgery.(1 day)
