NCT04750512

Brief Summary

The Erectore Spinae Plane Block (ESP Block) is a recently described technique for regional anesthesia that has shown promising results in the treatment of pain after thoracic surgery. It involves the injection of local anesthetic behind the musculature of the back. The investigators intend to compare this technique with a more standardized one, the TAP Block, which involves injection of anesthetic behind the musculature of the abdomen. 50 patients undergoing robotic inguinal hernia repair under general anesthesia will be randomly selected to receive, in addition to general anesthesia, either the ESP block or the TAP block. Patients receiving an ESP Block will also receive an injection of saline solution in the TAP injection site, and the other way around. This will prevent preconceived ideas on either technique to influence the evaluationso of the effect. Pain scores and consumption of pain medication will be recorded during the 24 hours following the operation to compare the effect of the two techniques.

  • Total dose of rescue opioids

    in the first 24 hours after surgery

  • Time of first walk after surgery

    24 hours

  • Episodes of urinary retention

    24 hours

  • Need for anti-nausea medication (dosage, doses and time points)

Interventions

ESP blockPROCEDURE

US guided ESP infiltration (saline solution vs Ropivacaine 0.2% according to randomization): bilateral injection of 30ml (60ml total) under US guidance between the deep fascia of erector spinae muscle and the the two transverse process at the level of the 10th thoracic vertebrae

real ESP, placebo TAP
TAP blockPROCEDURE

US guided TAP block (saline solution vs Ropivacaine 0.2% according to randomization): bilateral injection of 30ml (total 60ml) under US guidance in the plane between the internal oblique and transversus abdominis muscles at the level of the midaxillary line in the Petit triangle.

Masking Details
According to the randomization arm patients will receive: * sham US-guided ESP block + US-guided TAP block before laparoscopic hernia repair * US-guided ESP block + sham US-guided TAP block before laparoscopic hernia repair Allocation will take place immediately before the intervention by the means of access to centralized, real-time allocation through a computer program. Personnel not directly involved with patient care will prepare a saline solution and a ropivacaine solution which will be allocated respectively to ESP or TAP block according to randomization. This will allow blinding of patients, care providers and data collectors. Analysis will be done on allocation-concealed data, permitting blinded analysis. Unbliding will be permitted if by doing so harm to one or more patients can be avoided or treated. After information of one of the principal investigators, specific patient allocation will be retrieved from the randomization program.
