Erector Spinae Plane Block and Oblique Subcostal Transverse Abdominis Plane Block in Laparoscopic Cholecystectomy

May 23, 2018 updated by: Asst. Prof. Serkan Tulgar, M.D., Maltepe University

Evaluation of Postoperative Analgesic Effect of Ultrasound Guided Erector Spinae Plane Block and Oblique Subcostal Transverse Abdominis Plane Block in Laparoscopic Cholecystectomy, Randomised Controlled Study

Erector Spinae Plane Block is a newly defined regional anesthesia technique. Its use for many indications has been identified by case reports in the literature. As the investigators have considered that erector spinae plane block could be efficacious for providing postoperative analgesia in laparoscopic cholecystectomy, the investigators have implemented the application of this blockade into practice at the clinic.Oblique subcostal transverse abdominis plane block (OSTAP) is another regional anesthesia technic used for postoperative analgesia in laparoscopic cholecystectomy. Main purpose of this study is to compare the analgesic effect of ultrasound-guided erector spinae block and OSTAP in laparoscopic cholecystectomy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: ESP Block
Ultrasound-guided bilateral Erector spinae plane block performed at end of the surgery with 40 ml of a bupivacaine/lidocaine mixture. Perioperative and postoperative routine analgesic protocol will be performed (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block) Standard Pain Followup and Monitorization will be performed.
Numeric Rating Scale (NRS) pain score will be recorded from 20th minute in recovery room followed by 1.-3.-6.-12.-18.-24.hours. Intravenous meperidine administration at 0.5 mg / kg rescue analgesia was determined in patients with a NSR score of 6 and over in the postoperative collection room. It is planned that the patient will continue to follow the hourly NRS score in ward. Intramuscular diclofenac will be administered in this period if NRS 6 and if it is over, intravenous 0.5 mg / kg meperidine will be administered if NRS score is 6 or more after 2 hours. Salvage analgesic needs and times will be noted in detail, and the use of rescue analgesics, as well as NRS scores at designated hours, will be kept in a statistical evaluation.
A high-frequency linear ultrasound transducer will be placed in a longitudinal parasagittal orientation 3 cm lateral to T9 spinous process. The erector spinae muscles will be identified superficial to the tip of T9 transverse process. The patient's skin will be anesthetized with 2% lidocaine. A 17-gauge 8-cm needle will be inserted using an in-plane superior-to-inferior approach to place the tip into the fascial plane on the deep (anterior) aspect of erector spinae muscle. The location of the needle tip will be confirmed by visible fluid spread lifting erector spinae muscle off the bony shadow of the transverse process. A total of 40 mL of bupivacaine/lidocaine mixture will be injected.
Active Comparator: OSTAP Block
Ultrasound-guided bilateral OSTAP block performed at end of the surgery with 40 ml of a bupivacaine/lidocaine mixture. Perioperative and postoperative routine analgesic protocol will be performed (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block) Standard Pain Followup and Monitorization will be performed.
Numeric Rating Scale (NRS) pain score will be recorded from 20th minute in recovery room followed by 1.-3.-6.-12.-18.-24.hours. Intravenous meperidine administration at 0.5 mg / kg rescue analgesia was determined in patients with a NSR score of 6 and over in the postoperative collection room. It is planned that the patient will continue to follow the hourly NRS score in ward. Intramuscular diclofenac will be administered in this period if NRS 6 and if it is over, intravenous 0.5 mg / kg meperidine will be administered if NRS score is 6 or more after 2 hours. Salvage analgesic needs and times will be noted in detail, and the use of rescue analgesics, as well as NRS scores at designated hours, will be kept in a statistical evaluation.
The bilateral OSTAP will be performed at the end of the surgery. A total of 40 ml local anesthetic mixture (Bupivacaine and lidocaine) will be injected bilaterally with interfascial plane between the external oblique and transversus abdominis muscles
Sham Comparator: Control
Perioperative and postoperative routine analgesic protocol will be performed (consist of intravenous analgesics and intravenous patient-controlled analgesia) with no additional intervention (block) Standard Pain Followup and Monitorization will be performed. No block will be performed in this group.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain
Time Frame: 24 hours
Changes in Numeric Rating Scale (NRS) at rest and on movement will be recorded at intervals. NRS is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").
