A Study on MIS-DAA Safety and Application for Aged Patients with Nerve Blocking Anesthesia

1. Abstract 1.1. Background/Objective: To study the safety of Minimally Invasive Surgery - Direct Anterior Approach (MIS-DAA) and its application among aged patients with nerve-blocking Anesthesia. 1.2. Methods: In total, 54 patients (71 to 90 years of age) who accepted MIS-DAA in our hospital were divided into nerve-blocking Anesthesia (Group A) and waist hard joint Anesthesia group (group B; contrast group). The following indexes were observed: haemodynamics, albumin, deviations of haemoglobin and albumin before and after operation, operation time, intraoperative fluid intake, postoperative pain score, landing time (Shimoji time), duration of hospitalization, and postoperative complications. 1.3. Results: The two groups of patients were nearly identical (P>0.05) in terms of operation time and postoperative drainage, as well as deviations of haemoglobin and albumin before and after operation. However, haemodynamics and intraoperative fluid intake of group A were less than those of group B. Postoperative pain score, landing time, and duration of hospitalization of group A were better than those of group B (P 1.4. Conclusion: Compared with traditional combined spinal-epidural Anesthesia, nerve-blocking Anesthesia used during MIS-DAA provides minimal effects on haemodynamics, reduced postoperative pain, and more rapid recovery. 1.5. The Translational Potential of this Article: In our article, we introduced a minimally invasive surgery approach, which was conducted with nerve-blocking Anesthesia. It was simple and safety, especially for the aged patients. We believe that it has great translational potential used in the future hip joint surgery. 2.
