Preemptive Analgesic Effects of Popliteal Sciatic Nerve Block in Patients With Bilateral Hallux Valgus Surgery
Department of Anesthesiology and Pain Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea
background
Postoperative pain after orthopedic surgery is a very distressing symptom and a major component of the postoperative morbidity. Popliteal Sciatic Nerve Block (PSNB) are safe and have certain advantages, such as postoperative pain relief. The purpose of this study was to investigate the preemptive effect of ultrasound guided popliteal sciatic nerve block on postoperative acute pain in patients with bilateral hallux valgus (HV).
method
The patients of ASA I and II aged 20-80 years scheduled for bilateral HV surgery between June 2017 and May 2018 were included. After induction of general anesthesia, the leg to be operated first is decided randomly. After the operation of one leg is completed, intraneural extrafascicular PSNB is performed on both legs with 0.2% Ropivacaine and surgery is started on the remaining legs. The primary outcome of the study is to confirm the preemptive effect on the duration of the block and NRS.
results
In 8 of the 13 patients, an extension of the block duration (mean 69.1 min) of the pre-incisional block was observed. Two patients experienced pain at the same time in both leg, and the duration of the post-incisional block was longer in the three patients. Mean duration of PSNB is 842.5 min in Rt leg and 859.3 min in Lt leg.
conclusions
Preincisional intraneural extrafascicular PSNB increases the duration of block in patients undergoing bilateral HV op compared to postincisional PSNB.
