Abstract:
BACKGROUND: The rational choice of anesthesia for the elderly patients with hip surgery not only ensures the smooth operation, but also significantly reduces the incidence of postoperative complications. OBJECTIVE: To compare the clinical anesthetic effects between combined lumbar plexus-sciatic nerve block and hypobaric ropivacaine spinal anesthesia in hip joint surgery of elderly patients. METHODS: Forty patients who were scheduled for hip joint surgery, at the age of 65-99 years old, American Society of Anesthesiologists grades II-III, were enrolled and randomly allocated to two groups: nerve block (n=20) and spinal anesthesia (n=20). In nerve block group, combined lumber plexus-sciatic nerve block was performed directed by a nerve stimulator under the guidance of ultrasound. In spinal anesthesia group, patients received single-dose hypobaric ropivacaine spinal anesthesia at L3-4interspace. Hemodynamic changes, anesthetic effects and perioperative adverse effects were recorded in both groups before and after anesthesia. RESULTS AND CONCLUSION: (1) The patients' heart rate and mean artery pressure in each group did not change significantly before and after anesthesia in the nerve block and spinal anesthesia groups (P > 0.05). (2) The onset time of anesthesia in spinal anesthesia group was significantly faster than that in nerve block group (P < 0.01). Hypobaric ropivacaine spinal anesthesia had a better analgesic effect during the surgery, which did not need extra intravenous anesthetics. The duration of motor and sense block was significantly longer in nerve block group than in spinal anesthesia group (P < 0.01). However, five patients in spinal anesthesia group needed extra intravenous anesthetics to finish the surgery. (3) No side effects were found in both nerve block and spinal anesthesia groups. (4) These indicated that compared to combined lumbar plexus-sciatic nerve block, hypobaric ropivacaine spinal anesthesia can provide a better analgesic effect during the hip joint surgery with stable hemodynamics. Moreover, hypobaric ropivacaine spinal anesthesia dose not increase the incidence of complications and has very good clinical application prospects.
