Not Applicable

Recruiting

• Conditions: Total Laparoscopic Hysterectomy
• Interventions: Device: acupuncture; Device: placebo acupuncture

• Registration Number: NCT05720884
• Lead Sponsor: Ilsan Cha hospital

Brief Summary

The goal of this pilot clinical trial is to learn about efficacy of acupuncture about blood pressure fluctuation during total laparoscopic hysterectomy in patients with uterine fibroid.

Participants will receive two times of acupuncture treatment before surgery and researchers will compare to see if acupuncture treatment would stabilize blood pressure fluctuation especially from induction time to post-incision moment.

Detailed Description

After sufficient explanation about the purpose and methods of this clinical study by a researcher, the subject who voluntarily decided to participate and signed a written consent will be evaluated for eligibility at the screening visit. Eligible subjects will be determined as acupuncture group and a placebo control group according to the randomization. Acupuncture treatment is performed twice, one day before surgery and the same day.

On the day of surgery, after entering the operating room, monitoring equipments (non-invasive blood pressure monitor, pulse oxygen saturation, electrocardiogram, anesthesia depth sensor, neuromuscular monitor) will be installed and vital signs including pulse rate, blood pressure, oxygen saturation are measured.

Anesthesia was induced with an anesthetic (intravenous propofol 1-2.5 mg/kg, IV), an analgesic (remifentanyl 0.2mg/hr, IVF), and a muscle relaxant (intravenous rocuronium 0.6-1.2 mg/kg). After induction of anesthesia, anesthesiologist performed tracheal intubation maintaining an appropriate depth of anesthesia (Sedline \< 50). Mechanical ventilation started keeping end-tidal CO2 pressure of 25-35 mmHg). Then, an additional venous tube was secured. Additional disinfection process was performed, surgery is prepared.

With the patient in the lithotomy position and under the general anesthesia, the abdomen was prepared, painted and draped with the usual manner. The uterine elevator was inserted. Skin incision was performed and trocar was inserted. The CO2 gas was infused to make pneumoperitoneum which pressure was reached to 12mmHg. Entering into the abdominal cavity, the patient position was changed to the Trendelenburg position. And then the pelvic cavity and whole abdomen were examined. Bilateral pelvic side wall triangles were opened in parallel to infundibulopelvic ligament and ureter dissection was done. The ureteral course was identified, and then the right round ligament and ovarian ligament were coagulated with bipolar endocoagulator, cut with endoscissors. The left sided uterine ligaments were manipulated with the same method as above. The bladder flap was pushed and posterior broad ligament was mobilized. Bilateral uterine vessels were skeletonized and bilateral uterine vessels were coagulated and then cut. Circumferential colpotomy was done with unipolar scissor, and the uterus was removed transvaginally and then vaginal cuff was closed intracorporeal continuous suture. Hemostasis and ureteral peristalsis were assured and abdominal cavity was irrigated with normal saline. The subcutaneous tissue and the skin were closed layer by layer. In all processes, a qualified anesthesiologist whose clinical experience of more than 10 years will control the analgesic or anesthetic injection rate and inhalation gas concentration to maintain the appropriate blood pressure and depth of anesthesia.

Arm && Interventions

Group	Intervention	Description
acupuncture group	acupuncture	A total 10 acupoints of bilateral PC6, PC5, SP3, KI3, and ST36 will be chosen for the intervention group, also known as the acupuncture group. The depth of acupuncture will be varied by participant by participant. After acupuncture needles be inserted, the needles will be manually manipulated to obtain pre-determined sensation, the De Qi. Then, acupuncture will remain inserted for 20 minutes.
placebo group	placebo acupuncture	Ten other points, which are not official acupoints and those are not on the median nerve or peroneal nerve, will be chosen for the placebo group.

Primary Outcome Measures

Name	Time	Method
changes in mean blood pressure	At operation time	the difference between the highest mean blood pressure and the lowest mean blood pressure from the induction of anesthesia to the post-incision period

Secondary Outcome Measures

Name	Time	Method
numeric rating scale for pain	before operation(operation date), at the end of operation moment	numeric rating scale is a 11 point scale that defined point 0 as totally painless state, and point 10 as extreme pain as imaginable as possible.
Spielberger's State-Trait Anxiety Inventory (STAI)	before operation(operation date), at the end of operation moment	State-Trait Anxiety Inventory (STAI) consists of two categories, twenty items of questionnaire to assess state anxiety (STAI-S) and another twenty items to assess trait anxiety (STAI-T). STAI varies from a minimum score of 20 to a maximum score of 80. Lower scores means presence of less anxiety (no or low anxiety 20-37, moderate 38-44, and high anxiety 45-80).
incidence of hypotension	At the end of operation moment	Total incidence count of hypotension events, determined as lower than 80% of baseline or systolic blood pressure below 90
blood pressures according to predetermined timepoints	At operation time	systolic blood pressure, diastolic blood pressure and mean blood pressure values at entering operation room, induction time, intubation time, venous tube insertion, preparation time, skin incision, and gas inflation.
incidence of hypertension	At the end of operation moment	Total incidence count of hypertension events, determined as systolic blood pressure over 160
incidence of tachycardia according to predetermined timepoints	At the end of operation moment	heart rate values at entering operation room, induction time, intubation time, venous tube insertion, preparation time, skin incision, and gas inflation.
incidence of bradycardia according to predetermined timepoints	At the end of operation moment	heart rate values at entering operation room, induction time, intubation time, venous tube insertion, preparation time, skin incision, and gas inflation.
total use of remifentanil	At the end of operation moment	Use of remifentanil dosage will be surrogate markers of stable general anesthesia.
EuroQoL-5 Dimensions - 5 Levels (EQ-5D-5L)	before operation(operation date), at the end of operation moment	The EQ-5D-5L is used to assess effects on patients' quality of life. The questionnaire consists of questions in five areas (mobility, self-care, usual activities, pain, and anxiety/depression) that ask about the patient's current state of health. Answers are provided on a 5-point Likert scale.
