Effectiveness of Postoperative Analgesia by Ultrasound Guided Popliteal Sciatic Block and Adductor Canal Block in Patients Undergoing Below Knee Surgeries: A Prospective Study

View through CrossRef
Background: Central neuraxial block and general anaesthesia in patients with significant comorbidities are associated with considerable peri-operative morbidity and mortality. This study aims to determine the efficacy of combined popliteal sciatic and adductor canal nerve block for postoperative pain relief in patients undergoing below-knee surgeries. Objectives: Time for the first requirement of rescue analgesia. Total Dose of analgesia required in 24 hours after surgery, patient Satisfaction score. Methods: Sixty-four patients with the American Society of Anesthesiologists' (ASA) physical status grades I and II, aged 18–60 years, scheduled for below-knee surgery from April 2024 to April 2025, were enrolled in this prospective study. All patients received an ultrasound-guided popliteal sciatic block with 20 mL of 0.25% bupivacaine and an adductor canal block with 10 mL of 0.25% bupivacaine. Postoperative analgesia was assessed using visual analogue scores at 2, 6, 12, and 24 hours. Rescue analgesia with inj. Tramadol 0.5- 1 mg/kg IV was given when the VAS score was more than 5. Patient's satisfaction was assessed using Likert's satisfaction scale (5-point scale) from dissatisfied to extremely satisfied. The first analgesic requirement time and total tramadol used in the first 24 hours were noted. Descriptive statistics for the study were calculated, and the data were analysed using the SPSS Statistics 21.0 program. Results: VAS scores were significantly lower. The p-value for the VAS score was <0.0001. The mean duration of postoperative analgesia was significantly longer. Analgesic consumption was also very low and statistically significant. Patient satisfaction scores were also substantial and very much comfortable. Conclusion: Ultrasound-guided combined popliteal sciatic and adductor canal block is an effective analgesic technique for patients undergoing below-knee surgeries.
