The freezing of nerves (cryoneworelysis) before knee surgery shortens the period of inpatient stay, and also significantly reduces postoperative pain and the need for opioid analgesics, according to the Internet publication for girls and women aged 14 to 35. Pannochka. net This was reported by staff of the University of Louisiana (USA).

The scientists focused on anesthesia for the reason that procedures such as knee arthroplasty alone are generally very effective, but immediately after surgery, patients complain of severe pain that may threaten rehabilitation and the end result of surgical treatment.

"In our study, patients who underwent cryo-neurolisis before surgery were significantly less in hospital and received fewer opioids, and the pain level was lower in the first 12 weeks after surgery," says Dr. Vinod Dasa in a press release, , Professor of Clinical Orthopedics at the Faculty of Medicine LSU.

In the course of their work, the researchers analyzed 100 case histories of patients who underwent arthroplasty of the knee joint in the orthopedics department of LSU Health Hospital in New Orleans. Of these, 50 patients underwent cryoneworelysis before the operation, and in the remaining 50 cases the standard protocol for TKA was fully complied with, without freezing nerves.

The analysis showed that in the first group only 6% of patients remained in the hospital 2 or more days after the operation, while in the control group (without cryo-neurolisis) there were 67%. Almost 50% of patients from the first group left the hospital as early as the day of the operation, and in the second group of these patients it was only 14%.

Significantly, in the postoperative period, patients after cryo-neurology received 45% less narcotic analgesics. According to the results of a standard survey, the pain level in the first 12 weeks after the operation was significantly lower than in the control group.

Dr. Dasa believes that cryo-neurolysis should become part of a new protocol for arthroplasty of the knee joint, as it helps not only to improve the patients' well-being and the outcomes of surgical treatment, but also offers significant economic benefits by reducing the length of stay in the hospital and the need for analgesics.
