Perioperative Electroacupuncture on Postoperative Analgesia in Prostatectomy
Brief Summary
The aim of the present study is the comparison of the efficacy of the perioperative application of a multimodal analgesia model to the patients, combing common used analgesics via intravenous (IV) route, such as tramadol and ketamine, with or without the Electroacupuncture (E/A) technique application and the frequency of side effects accession.
Intervention / Treatment
-
Tramadol (DRUG)If NRS scale was ≥3, PPI scale ≥2 and the algometer count ≤0,5Kg it was assumed as a non acceptable pain treatment. Tramadol 50mg IV bolus was firstly administered to the patients.The aim was that the Tramadol 24h dose would not exceed 600mg
-
Ketamine (DRUG)ketamine 10mg bolus IV 30min before the end of the surgery and co instantaneously the CIV infusion of ketamine, in subanesthetic doses, 0,15mg/kg/h started with continuous infusion in an adjustable flow disposable pump (paragon®). Ketamine's dose was altered so as not to exceed the 300mg/24h.
-
Morphine (DRUG)If NRS scale was ≥3, PPI scale ≥2 and the algometer count ≤0,5Kg it was assumed as a non acceptable pain treatment. Tramadol 50mg IV bolus was firstly administered to the patients and if the NRS scale was not decreased at least about 2 points after 30 minutes, morphine 2mg IV was then administered and it could be repeated
-
sedation (PROCEDURE)If the patient had sedation score \>2 then the analgesic infusion would be stopped, the patient would be assessed again in 1 hour and the infusion would start with the same or decreased flow.
-
rescue analgesia (PROCEDURE)Meanwhile - 45min,2h,6h,12h and 24h- if the patients had acute pain, the physician would call the anesthesiologist and a new assessment would take place with the relative interventions.
-
Parecoxib (DRUG)An hour before the end of the surgery all patients were administered with parecoxib 40mg (IV)
-
paracetamol (DRUG)30min before the end of the surgery paracetamol 20mg/kg (IV).

Seventy patients were scheduled for radical prostatectomy, were recruited to this prospective single-blind, were randomized and placebo-controlled by trial. They were randomly divided into two groups of 35 patients each by a computer-generated randomization sequence, the TKE (Tramadol + Ketamine + Electroacupuncture), and TK (Tramadol + Ketamine + placebo Electroacupuncture.The randomization performed by the certified acupuncturist.
Patients were anesthetized with the same protocol by five anesthesiologists, who were not involved in the postoperative assessment of the patients, but were aware in which group acupuncture was used and in which not. Both groups, TKE and TK, were administered tramadol 1.5mg/kg and ketamine 10mg bolus IV 30min before the end of the surgery and co instantaneously the CIV infusion of tramadol 0.15mg/kg/h and ketamine, in subanesthetic doses, 0.15mg/kg/h started with continuous infusion in an adjustable flow disposable pump (paragon®).Ketamine's dose was altered so as not to exceed the 300mg/24h. An hour before the end of the surgery all patients were administered with parecoxib 40mg (IV) and 30min before paracetamol 20mg/kg (IV).
In TKE group when the closure of the abdominal walls started, a certified acupuncturist expert put needles, Ener-Qi 0.26Χ25mms, in LI4 point at 2cm depth in both hands and E/A was applied for 30min with the E/A stimulator ITO ES-160 in constant pulse program with 300μs duration and 100Hz frequency. After the needles were connected to the E/A stimulator, they were secured by adhesive tape. The response which certified the right needle placement was the adjacent muscular twitch. Thereafter the electroacupuncture machine was deactivated and after the awakening of the patients, E/A was administered in ST36 and LI4 points for 30min with 4Hz frequency. The electrodes were connected to each other in every point, as the right with the left point of LI4 and the right with the left point of ST36. In the TK group the needles were not inserted in the skin but they were put atop the skin and were secured by adhesive tape, the indicator light was on but no electrical current was applied. The patients were told that they may or may not feel electrical current because of its very high frequency.
The study was single blind as patients although they were informed for the Electroacupuncture (E/A) technique during the first session they were anesthetized and the second one was after the awakening of anesthesia and they didn't understand it. On the other hand anaesthesiologists and the certified acupuncturist during the EAc application knew in which group patients belong although they did not deal with them postoperatively. However, patient assessments were performed at standard time points as 45 min in recovery and at 2 h, 6 h, 12 h and 24 h after surgery in the ward by another anaesthesiologist who was not present during the surgery or the recovery room for the first 30 min.

In TK group when the closure of the abdominal walls started, a certified acupuncturist expert put needles, Ener-Qi 0.26Χ25mms, in LI4 point in both hands, the needles were not inserted in the skin but they were put atop the skin and were secured by adhesive tape. For 30min in the E/A stimulator ITO ES-160 the indicator light was on but no electrical current was applied. Thereafter the E/A device deactivated and after the awakening of the patients, it was connected in ST36 and LI4 points for 30min with the same technique. The electrodes were connected to each other in every point, as the right with the left point of LI4 and the right with the left point of ST36. The patients were told that they may or may not feel electrical current because of its very high frequency.

Primary Outcomes
-
-
The electronic pressure algometer device was applied 2cm bilateral the middle of the midline extraperitoneal lower abdominal incision and were recorded the pain threshold. It converted in Kg
-
Nausea:yes/no vomiting:yes/no pruritus:yes/no bowel movement:yes/no Sedation scale 0-3, from 0= awake or sleepy that answers to the questions to 3=asleep who doesn't awake not even with a prod
-
If NRS scale was ≥3, PPI scale ≥2 and the algometer count ≤0,5Kg it was assumed as a non acceptable pain treatment. Tramadol 50mg IV bolus was firstly administered to the patients and if the NRS scale was not decreased at least about 2 points after 30 minutes, morphine 2mg IV was then administered and it could be repeated. The aim was that the Tramadol 24h dose would not exceed 600mg. So with rescue analgesia, tramadol or morphine in mg, we count the total amount of opioids administered
-
Cortizol levels: ug/dl
Secondary Outcomes
-
Spielberger State Trait Anxiety Inventory (STAI Y-6 item) 1-4, where 1=not at all and 4 =very much so.
-
Verbal Rating Scale (VRS) with 6 levels of satisfaction 1-6,from 1=very dissatisfied to 6= very satisfied
