Comparison of Postoperative Analgesia in Patients Undergoing Ileostomy Closure with and Without Dual Transversus Abdominis Plane (TAP) Block: A Randomized Controlled Trial

Abstract

Background and AimsMultimodal analgesia comprising opioid, paracetamol, and non-steroidal anti-inflammatory drugs is used for managing postoperative surgical pain after ileostomy closure (IC). We investigated the efficacy of unilateral dual transversus abdominis plane (TAP) block to reduce morphine consumption in the first 24 hours along with a reduction in visual analogue score for pain and in postoperative nausea/vomiting.MethodsThis was a single-center, investigator-initiated, prospective, parallel-group, placebo-controlled randomized study involving patients undergoing IC under general anesthesia. We recruited 55 patients in two groups: 28 in a TAP group and 27 in a placebo group. The TAP group patients received 30 mL of 0.375% bupivacaine: 15 mL by a posterior TAP approach and 15 mL by a subcostal approach using ultrasonography. Patients in the placebo group received 30 mL normal saline (placebo) using the same approaches. Blocks were administered at the end of surgery before extubation. To monitor for the primary outcome—24-hour morphine consumption for both groups—patients were transferred to a high-dependency unit. The secondary outcome was to compare postoperative nausea/vomiting in both groups.ResultsThe demographic data, gender distribution, ASA physical status, duration of surgery, and time of first morphine dose was comparable in both groups. The 24-hour morphine consumption was 3.29±2.78 mg and 9.23±2.94 mg for the TAP and placebo groups, respectively, which was statistically significant (P=0.001).ConclusionDual TAP block reduces opioid consumption in the first 24 hours after an IC and can facilitate early recovery with less adverse effects seen than with opioids and NSAIDs.

A randomized clinical study to compare postoperative pain relief in ilioinguinal nerve block versus transversus abdominis plane block following inguinal hernia repair surgery

“…IIIH block is routinely used as anesthetic technique for surgeries in inguinal hernia and lower abdominal surgeries. 8 TAP block has gained acceptance in recent years after Rafi initially described it in 2001 using landmark-based techniques; the practitioner must identify the triangle of Petit. McDonnell describes "double pop" sensation as needle pierces the external oblique muscle and internal oblique muscle.…”

A Retrospective Comparison of Three Patient-Controlled Analgesic Strategies: Intravenous Opioid Analgesia Plus Abdominal Wall Nerve Blocks versus Epidural Analgesia versus Intravenous Opioid Analgesia Alone in Open Liver Surgery

“…These blocks appear promising as analgesia is achieved while reducing opioid requirements. Patients may be able to have improved respiratory function leading to a shorter length of hospital stay and better satisfaction of the patients [ 26 , 27 , 29 , 30 , 31 , 32 , 33 ]. Generally, an open hepatectomy incision requires dermatome coverage from approximately T6 to T10, which can be covered by bilateral TAP blocks or left-sided rectus sheath block in addition to a right-sided TAP block [ 28 ].…”
