Recruiting

• Conditions: Postoperative Pain; Analgesia; Postoperative Nausea
• Interventions: Drug: Lidocaine IV; Drug: Saline

• Registration Number: NCT06423456
• Lead Sponsor: Afyonkarahisar Health Sciences University

Brief Summary

Intraoperative lidocaine infusion is a frequently preferred method in surgical procedures due to its reducing the need for opioids, providing better postoperative pain control, reducing postoperative nausea and vomiting and increasing rapid recovery. Our aim in this study is to show the effect of intraoperative lidocaine infusion on reducing complications such as pain, nausea, vomiting, and the need for opioid analgesia that occur after hysteroscopy operations, which are often performed in gynecology clinics.

Detailed Description

Hysteroscopy abnormal uterine bleeding, infertility, endometrial pathologies, uterine fibroids,it is a method that is often used in the diagnosis and treatment of pathologies such as intrauterine synechia.

Hysteroscopy; observation of the inner layer of the uterus with a special optical instrument with a cold light source and it is the process of making intrauterine interventions using small hand tools. General anesthesia or with intrauterine fluid after dilating the cervix under regional (epidural/peridural) anesthesia it is filled and a thin telescope-like optical device (hysteroscope) is transmitted into the uterus. This way the uterine cavity is observed. Hysteroscopy is used for diagnostic purposes as well as for therapeutic purposes it can be applied.

General Anesthesia (GA) is often the preferred method for operative hysteroscopy.Intraoperative lidocaine infusion reduces the need for opioids, postoperative pain control is better due to the fact that it reduces postoperative nausea, vomiting and increases rapid recovery, which is often preferred in surgical procedures. 150 patients who are scheduled to undergo hysteroscopy will be included in the study. Hysteroscopy the patients to be applied will be divided into two groups as research and control groups. To both groups 75 patients will be included each. General anesthesia during the procedure for patients in the research arm intravenous lidocaine of 0.15 ml/kg 1% will be administered intraoperatively before and during the procedure a 1% lidocaine infusion(at a dose of 0.2 ml/kg/hour) will be performed. In the control group, if 0.9% saline solution will be used instead of lidocaine.

Pain measurement using visual analog scale (VAS) for postoperative pain after surgery will be done. At the same time, intraoperative analgesic use of patients, postoperative nausea-vomiting and antiemetic uses will be recorded.

Arm && Interventions

Group	Intervention	Description
Research group	Lidocaine IV	During the procedure, intravenous lidocaine of 0.15 ml/kg 1% will be administered intraoperatively before general anesthesia and infusion of lidocaine of 1%(at a dose of 0.2 ml/kg/hour) will be performed during the procedure.
Control group	Saline	In the control group, 0.9% saline solution will be used instead of lidocaine.

Primary Outcome Measures

Name	Time	Method
Visual analog scale (VAS)	24 hours	After the hysteroscopy procedure is completed, in the postoperative anesthesia care room, postoperative, 30. and 60. in minutes, 4. per hour and 24. pain measurement will be performed for patients per hour using a visual analog scale (VAS) for postoperative pain. In this scale, patients' pain between 0-10 (0=no pain, 10=very severe pain) will be questioned. Dec. The doctor who performed the measurement will not know which drug infusion was made. NSAIDs will be administered to patients with a VAS score \> 4. Opioid analgesics will be administered to patients whose pain does not go away. At the same time, patients' intraoperative analgesic use, postoperative nausea-vomiting and antiemetic use will be recorded.
