Bilateral Retromuscular Rectus Sheath Block Catheters Usage for Early Postoperative Analgesia After Laparotomic Gastrectomy.

Postoperative Pain Clinical Trial

Official title: Bilateral Retromuscular Rectus Sheath Block Catheters Usage for Early Postoperative Analgesia After Laparotomic Gastrectomy.

Status Active, not recruiting

Clinical Trial Summary

In early postoperative period, the occurrence of severe pain after open major upper GI surgery is a significant issue. The study is aimed to access the efficiency of rectus sheet block with continuous bupivacaine infusion catheters into retromuscular space in providing an effective pain relief, decreasing opioid consumption and enhancing postoperative recovery.

Clinical Trial Description

This prospective randomised case-control experimental study is being conducted in Riga East University Hospital (Latvia). Patients with total or subtotal open gastrectomy were divided into two groups - half patients in the Block group and half patients in the Control group. In the Block group and control group, retromuscular catheters in the m. rectus abdominis sheath is going to be placed before fascia closure. Catheters will be placed under the direct supervision of a surgeon throughout the operation wound on both sides of the incision. After surgery patients in the Block group will receive continuous 0.125% (10-12 mg/h) bupivacaine infusion through rectus sheath catheters for 72 h. Additionaly ketorolac or trimeperidine infusion will be performed if VAS of pains more than 30mm. If pains continue, additional opioids will be performed. Patients in the Control group received 0,9% NaCl solution 72 hours by using the same "easy pump" system, and ketorolac or trimeperidine injection if necessery Pain intensity will be assessed in both groups using 0-100 mm Visual Analog Scale (VAS) at 24, 48 and 72 hour intervals after surgery at rest and during movement (by asking the patient to bend legs). Postoperative complications, hospital stay, comorbidities, the time taken to start walking after the surgery, bowel movements (time until first stool) were all examined. ;
