A Study to Compare Laparoscopic to Echographic Assisted Transversus Abdominis Plane Block in Laparoscopic Colectomy

Laparoscopic- Vs Ultrasound-guided Transversus Abdominis Plane Block in Laparoscopic Colectomy: a Prospective Randomized Controlled Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 116 (actual)
• Sponsor: Davide La Regina · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this study is to compare the postoperative pain, the time needed and other clinical outcomes in patients who, during laparoscopic colectomy, will be injected with a local anesthetic (Ropivacaine) through an ultrasound guided technique performed by the anaesthesiologist or throught a laparoscopic assisted technique performed by the surgeon

Conditions

• Laparoscopic Colectomy
• Pain, Postoperative

Interventions

Type	Name	Description
PROCEDURE	laparoscopic-assisted Transversus Abdominis Plane (TAP) block	The anterior axillary line is used as landmarks. After insertion of the optic trocar, the peritoneum is visualized. A 14 Gauge needle is inserted 2 cm cranially respect the taken landmark through the skin until the penetration of the internal and external oblique fascias, identified as sudden lowering of resistance. A solution of 15 ml of Ropivacaine (0.2%) is then injected. The procedure is performed then 2 cm caudal to the first landmark on the same side. The procedure is than repeated identically on the contralateral side.
PROCEDURE	ultrasound-assisted Transversus Abdominis Plane (TAP) block	Whilst the patient is in the supine position, a high frequency ultrasound probe is placed transverse to the abdominal wall between the costal margin and iliac crest. The needle is introduced in plane of the ultrasound probe directly under the probe and advanced until it reaches the plane between the internal oblique and transversus abdominis muscles. Then 15 ml of local anaesthetic solution is injected. The needle is than retracted until its tip is positioned in the fascial plane between the internal and the external oblique muscles and a second bolus of 15 ml of local anaesthetic is injected. The procedure is than repeated identically on the contralateral side.
DRUG	Ropivacaine	a solution of 15 ml of Ropivacaine (0.2%) is injected for the treatment of post-operative pain after minimally invasive surgery (TAP block)
