Randomization will conduct based on permuted block randomization method. Each block will have capacity for 4 subjects; it means we will have 15 blocks and also one block of 2 patients (Totally 62 patients). Then, within each block, subjects will be randomly assigned to intervention or control group . Random assignment will be done using a random number table

تصادفی سازی براساس روش permuted block randomization انجام خواهد شد. هر بلوک دارای ۴ ظرفیت خواهد بود یعنی 15بلوک 4تایی و یک بلوک 2 تایی خواهی داشت (مجموعا 62بیمار).پس از آن در هر بلوک افراد به صورت تصادفی وارد گروه مداخله یا کنترل میشوند. تصادفی سازی در داخل هر بلوک بر اساس جدول اعداد تصادفی صورت خواهد گرفت.

Protocol summary
Study aim
Determination of the ultrasound-guided erector spinae plane block effect on the degree of the post laparoscopic cholecystectomy pain
Design
Clinical trial, with tow parallel groups, single blind, accidental with number of samples 62 and 31 sample in each group.
Settings and conduct
After selection of the patient, getting satisfaction, and monitoring in the recovery unit, the patient is positioned left laterally, the right side is prep and drep, the probe of sonography is located longitudinally at the level of T7 (lower border of scapula) and after determination the lower and upper transverse processes, the needle is inserted in plane toward the erector spinae plane muscle. 20 cc Ropivacaine 0/2% is injected into the fascia of erector spinae plane muscle (behind the transverse process). A PCIA pomp containing 12 cc fentanyl in 100 cc (6microgram /1 cc) is connected to patient in both groups. The flow of the pomp will be zero and the use of the bolus bottom is instructed to the patient. (bolus = 2 cc) the patient is delivered 12-mcg of fentanyl each time the pump is pressed (in one hour at most 48-mcg fentanyl). In the control group only the aforementioned pomp with the same setting and contents is inserted.
Participants/Inclusion and exclusion criteria
Inclusion criteria:
patients with ASA =< 2
patients with the age of 20-65 years old
Exclusion criteria: Emergent patients, History of allergy to Ropivacain,
analgesic consumption during the last 24 hours, BMI > 35
liver disease, renal disease and coagulopathy, Changing the plan of the surgery to the open cholecystectomy, occurrence of any problem during the operation
Intervention groups
Investigation of the ultrasound-guided erector spinae plane block effect on the degree of the post laparoscopic cholecystectomy pain
Main outcome variables
Degree of the pain in rest mood and coughing after the surgery during the specific time intervals
General information
Reason for update
In the design section, a randomized study was mentioned, but in the randomization section, "non-randomized" was mentioned, which was corrected. Also a secondary outcome was the administration of meperidine, which was corrected.
