Abstract
In the process of knee replacement surgery, the use of tourniquet technology for hemostasis is the most common method. But the adverse reactions of tourniquets in knee replacement surgery have become more prominent in recent years. More and more scholars have begun to advocate the optimization of the use of tourniquet technology, thereby controlling the use of tourniquet technology. In this study, 125 patient cases were randomly divided into four experimental groups for comparative analysis. The two sets of variables are whether to use tourniquet during surgery and use intravenous analgesia or nerve block analgesia. Studies have shown that when using a tourniquet for knee replacement surgery, the chance of hidden blood loss increases after use. The tourniquet was not used during the operation, the patient's thighs were swollen, and postoperative pain was reduced. Compared with intravenous analgesia, knee joint replacement with uncontrolled tourniquet combined with femoral nerve block has a better analgesic effect and can effectively relieve pain after knee replacement. Therefore, under the method of controlled hypotension combined with femoral nerve block, TKA surgery without using tourniquet technology is more conducive to early health recovery and pain relief after TKA surgery, as well as functional exercise and knee joint recovery during postoperative recovery.
Highlights
TKA has widely been used in medical clinical treatment in recent decades
With the maturity of surgical operation technology and the development of the prosthetic material industry in recent years, patients with knee arthritis will generally choose knee replacement surgery to cure inflammation in the late stage of arthritis[2]. e tourniquet is a common method of hemostasis in clinical research,andit isveryeffective in reducing bleeding during surgery. e tourniquet reduces the amount of bleeding during surgery, and has a good effect in providing a clean and clear surgical field of view;in recent years, with the theoretical point of view on the restrictive use of tourniquets[3], more and more scholars have begun to call for optimization and upgrading of tourniquet use methods
How to apply tourniquet in the surgical process to maximize the benefits of the tourniquet application during surgery has become a hot research in recent years. erefore, this study proposes a new method of use: the application of tourniquet under controlled hypotension combined with femoral nerve block [13]
Summary
TKA has widely been used in medical clinical treatment in recent decades. TKA surgery isveryeffective for the advanced management of knee arthritis, and it is arelativelymature and complete surgical method[1]. Reducing the amount of bleeding is an important indicator during the operation of TKA At this time, the use of tourniquet can reduce the amount of bleeding, and provide a clear vision and reduce the bleeding of the bone surface. The tourniquet can reduce the amount of bleeding during the operation, thereby providing the operator with a clear surgical field of vision, cleaner bone cement, and a better bone interface. Erefore, it is widely used in clinical applications of TKA It is currently controversial whether the use of tourniquets can really reduce the total blood loss during the perioperative period of TKA and improve the effect of recovering from the healing period after surgery [5]. It is currently controversial whether the use of tourniquets can really reduce the total blood loss during the perioperative period of TKA and improve the effect of recovering from the healing period after surgery [5]. e use of tourniquets during surgery may increase the chance of postoperative complications [6]. e application of the tourniquet technique in the TKA process will reduce the pain and swelling of patients
