Procedure: T7 Level Erector Spinae Plane Block
Procedure: T9 Level Erector Spinae Plane Block
Drug: control group
Registration Number
NCT04316416
Lead Sponsor
Gaziosmanpasa Research and Education Hospital
Brief Summary

In last years, erector spinae plane block is widely used in abdominal and thoracic surgeries. Laparoscopic cholecystectomy is one of the most commonly performed surgical operations. In this study, the investigators will evaluate the effectiveness of erector spina plan block with different injection levels for postoperative analgesia on patients undergoing laparoscopic cholecystectomy surgery.

Detailed Description

Three groups were planned for this study.Randomization was planned with the closed envelope method. İn the first group, the ESP(erector spinae plane) block procedure will be applied from the T7 level bilaterally and in the second group it will be applied from the T9 level bilaterally. ESP block procedure will not be applied in the third group and this group will be considered as the control group. A comparison of NRS (Numeric Rating Scale) and morphine consumption will be planned for all groups of patients at 1-th, 4-th, 8-th.,12-th and,24-th postoperative hours.

T7 Bilateral ESP blockT7 Level Erector Spinae Plane BlockUltrasound-guided bilateral Erector spinae plane block will performe at end of the surgery with 40 ml of a bupivacaine/lidocaine mixture by imaging T7 (7th thoracal vertebrae ) transverse process accompanied by ultrasound. Postoperative routine analgesic protocol planned (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block). Standard pain follow-up and monitorization will be performed.
T9 bilateral ESP blockT9 Level Erector Spinae Plane BlockUltrasound-guided bilateral Erector spinae plane block will performe at end of the surgery with 40 ml of a bupivacaine/lidocaine mixture by imaging transverse process T9 (9th thoracal vertebrae) by ultrasound. Postoperative routine analgesic protocol planned (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block). Standard pain follow-up and monitorization will be performed.
Control groupcontrol groupPostoperative routine analgesic protocol will be performed (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block) Standard pain follow-up and monitorization will be performed. No block will be performed in this group.
Primary Outcome Measures
NameTimeMethod
Postoperative pain changeup to 24 hours

It was planned to check the change in the NRS scores of patients at 1.,4.,8.,12.,24 hours for evaluation of efficacy level and effect time of ESP block procedure from different levels.

A NRS involves asking the patient to rate his or her pain from 0 to 10 (11 point scale) with the understanding that 0 is equal to no pain and 10 is equal to worst possible pain.

Postoperative morphine consumption changeup to 24 hours

It was planned to check the change in the morphine consumption of patients at 1.,4.,8.,12.,24 hours for evaluation of efficacy level and effect time of ESP block procedure from different levels.

Secondary Outcome Measures
NameTimeMethod
side effectsup to 24 hours

Rate of side-effect occurrences (such as rate of vomiting,nausea,shoulder pain) between groups will be compared.

number of blocked dermatome sitesup to 24 hours

number of blocked dermatome sites will be recorded.
