Abstract:

BACKGROUND: In the elderly patients with a variety of diseases, poor physical and compensatory ability results in a high demand for anesthesia during hip replacement and internal fixation. Lumbar epidural anesthesia with ropivacaine is the commonly used method of narcotic analgesics, but this method of anesthesia has been less studied in elderly hip replacement and internal fixation. 
OBJECTIVE: To investigate the effects of lumbar epidural anesthesia with ropivacaine in elderly hip replacement and internal fixation.
METHODS: Data of fifty elderly patients with hip replacement implants and internal fixation, who were treated in the Department of Orthopedics, Affiliated Hospital of Xizang Minzu University from February 2014 to August 2015, were analyzed. 50 patients were randomly divided into continuous epidural anesthesia group and ropivacaine lumbar epidural anesthesia group, with 25 patients in each group. Anesthetic effect was compared. Self questionnaire on risk factors was used for non-conditional Logistic multivariate analysis between the two groups.
RESULTS AND CONCLUSION: (1) Anesthetics onset time, the amount of local anesthesia, the use of trimetaphan camsilate agent number, complete block time, heart rate after anesthesia and complication rate were significantly less in the ropivacaine lumbar epidural anesthesia group than in the continuous epidural anesthesia group (P < 0.05). (2) The highest block level, Bromage score, mean arterial pressure after anesthesia and anesthesia satisfaction rate were significantly higher in the ropivacaine lumbar epidural anesthesia group than in the continuous epidural anesthesia group (P < 0.05). (3) Logistic multivariate analysis on postoperative cognitive dysfunction showed that postoperative cognitive dysfunction was strongly associated with age, education, complications, and hip arthroplasty (P < 0.05).
(4) Results verified that lumbar epidural anesthesia with ropivacaine showed ideal effects in hip arthroplasty and internal fixation. Postoperative recovery was rapid, and it is safe and reliable.
