What this Trial Is About
The trial investigates severe pain management during thigh and knee surgeries, focusing on comparing two regional anesthesia techniques called supra-inguinal fascia iliaca block (S-FIB) and infra-inguinal fascia iliaca block (I-FIB). These blocks aim to ease spinal positioning and provide postoperative pain relief. The study is a randomized controlled trial involving 60 patients aged 30 to 60 undergoing such surgeries, assessing pain control and patient satisfaction. Participants will be randomly assigned to one of two groups: Group A receives the supra-inguinal fascia iliaca block with 30 ml of 0.125% bupivacaine, and Group B receives the infra-inguinal fascia iliaca block with the same dosage. Both blocks are performed under ultrasound guidance before surgery by experienced anesthesiologists. The blocks are administered using a sterile technique with specific ultrasound probe positioning to guide needle placement for precise drug delivery. During the study, patients' pain levels are recorded at rest and on movement before and after the block using a numeric rating scale. Researchers will measure how easily patients can be positioned for spinal anesthesia, the duration of postoperative pain relief, and patient satisfaction using standardized scales. Monitoring includes heart rate, oxygen levels, and blood pressure during and after surgery. Follow-up pain assessments occur every 2 hours for 12 hours post-surgery, with rescue pain medication provided if needed.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Day of surgery
Participants receive either supra-inguinal or infra-inguinal fascia iliaca block with local anesthetic before undergoing spinal anesthesia and lower limb surgery. Pain scores and ease of spinal positioning are assessed during this period.
1 preoperative visit and continuous monitoring during surgery
Duration - 12 hours post surgery
Participants are monitored in the ward after surgery with pain assessments every 2 hours up to 12 hours. Rescue analgesia is given as needed, and patient satisfaction is measured after 12 hours.
Approximately 6 visits for pain assessment over 12 hours
