Optimizing Postoperative Pain Control After Laparoscopic Colorectal Surgery

Optimizing Postoperative Pain Control After Laparoscopic Colorectal Surgery by Supplementing Ultrasound-guided Erector Spinae Plane Block With Ketamine or Transdermal Fentanyl Patch

Erector spinae plane block (ESPB) is a novel regional block technique that was proven to have superior outcomes in relieving postoperative pain in colorectal surgeries.Ketamine enhances the impact of local anaesthetics by reducing the duration and extent of motor block while shortening the onset of sensory and motor block.Transdermal Fentanyl Patch (TFP) was better than transdermal buprenorphine in postoperative analgesia following abdominal surgeries.
