The Effect of Preoperative Administration of Oral Tizanidine on the Postoperative Pain and Sleep Quality

The majority of lower limb fractures treated with surgery often leading to significant morbidity and mortality. Despite improvements in perioperative care, about 20% suffer from severe postoperative complications. So, effective perioperative pain management is crucial in this demographic to ensure optimal recovery and reduce complications. (1) Controlling the postoperative pain often begins in recovery room by using opioids, especially morphine. However, systemic opioids may develop many complications such as nausea and vomiting, apnea, respiratory depression, and urinary retention. To reduce the complications and consumption of the opioids, other procedures are recommended. One of these procedures is preemptive analgesia(2).

In addition to pain, disrupted sleep quality is a common challenge, with evidence suggesting a bidirectional relationship where poor sleep exacerbates pain, and pain further disrupts sleep (3). Addressing both pain and sleep disturbances in the perioperative period is therefore critical for enhancing recovery and improving overall patient outcomes
