简要总结
Transversus abdominis plane (TAP) and Quadratus lumborum (QL) blocks are used for the management of acute pain treatment, especially after the lower and upper abdominal surgeries.
The TAP block which is one of the abdominal truncal blocks is performed with the blockage of the nerve group which innervates the anterior abdominal muscle wall layers. However, in QL block, the local anesthetic agent spreads through the abdominal wall and paravertebral space with the help of the perimuscular fascia to maintain the somatic analgesia.
The investigators' aim in this study, to investigate the effect of the TAP and QL blocks on peroperative and postoperative analgesic consumption in children undergoing unilateral elective orchiopexy.
详细描述
American Society of Anesthesiologists Physical Status Classification System (ASA) class I-III, aged 6 month-12 years old children undergoing unilateral elective orchiopexy with general anesthesia will be recruited, after the informed consent will be obtained from the parents of the patients, in this randomized controlled trial.
After the premedication with ketamine and midazolam will be performed, the patient will be brought to the operation room. After the induction with thiopental 5mg/kg, fentanyl 1mcg/kg, rocuronium 0.6mg/kg, patients will be intubated. The maintenance of the anesthesia will be provided with sevoflurane.
Subsequently, before the surgery, the patients will be randomized and separated into 2 groups. The investigators will apply the QL block to the first group and TAP block to the other group. 0.4 ml/kg %0.25 bupivacaine will be used as a local anesthetic agent in both group.
In the peroperative period, if the additional analgesia will necessary, remifentanyl 0.1mcg/kg/min will be started, and dosage will be adjusted according to heart rate and blood pressure. If the blood pressure or heart rate will increase more than 20% from the preoperative basal value will be defined as the need for the analgesia.
In the postoperative period, all cohort will be assessed by a blinded investigator at the 10,20,30th minutes, 1,2nd hours in the recovery room, 6th hour in the surgical ward, Face, Legs, Activity, Cry, Consolability Scale (FLACC) will be used for the pain evaluation. 16th and 24th hours will be monitored by the telephone visit from the parents, the pain will be evaluated with the Wong-Baker Faces Pain Rating Scale due to the same-day surgery concept.

结局指标
主要结局
Total Analgesia Consumption
时间窗: 24 hour
The required analgesic consumption within the framework of the predetermined protocol will be recorded by the nurses and doctors who do not know which block is used. After discharge, the family will be called by phone to find out the amount of additional analgesic need.
The Effect on Perioperative and Postoperative Pain
时间窗: 24 hour
The investigator will screen and record perioperative hemodynamic parameters for the perioperative pain evaluation. The Face, Legs, Activity, Cry, Consobility (FLACC) Score will be used for evaluation of the postoperative pain. The FLACC pain assessment score is evaluated out of 10 points. While a score of zero defined as no pain, 1-3 is mild pain, 4-6 is moderate pain, 7-10 is severe pain, respectively. If the score is 4 and above, additional analgesic administration will be planned.
The Effect on Post-discharge Pain
时间窗: 24 hour
Post-discharge pain will be assessed by the Wong Baker Score. Pain will be evaluated based on six facial expressions between zero and ten points. If the score is four or more, additional analgesic administration will be planned.
次要结局
- Parent satisfaction score(24 hour)
