Clinical Trial Summary

This study aims to compare Laparoscopic assisted LTAP (Transversus Abdominis Plane) to standard port-site infiltration in terms of post-operative visual analogue scores (VAS) for pain at 3, 6, 12 and 24 hours following laparoscopic appendicectomy Tap Block is a standard conventional analgesia protocol for laparoscopic appendicitis used in Beaumont Hospital, and other hospitals throughout Ireland. The medicinal product for both groups is the same - Bupivacaine. The mode of administration is what this study is reviewing: Control group (Standard port site infiltration) and Study Group - Laparoscopic Transversus Abdominis Plane Block


Clinical Trial Description

Title: Randomised Controlled Trial to compare Laparoscopic Transversus Abdominis Plane Block (LTAP) for appendicectomy versus standard treatment Short title: (TAP Block Study) Laparoscopic Transversus Abdominis Plane Block for Appendicectomy - Single-Blinded Randomised controlled study Objectives: Primary objectives: To compare LTAP to standard port-site infiltration in terms of post-operative visual analogue scores (VAS) for pain at 3,6, 12 and 24 hours following laparoscopic appendicectomy Secondary objectives: Post-operative Opioid requirement Time to first mobilisation post-operatively Length of stay in hospital Quality of Life Questionnaire (at 1 week and 1 month post discharge) (EQ5DL) Type of trial: Multi centre Single blinded randomised control trial. (Beaumont Hospital and 3 other Dublin Hospitals) Trial design and methods: Study design: randomised controlled Single blind study. Patients will be allocated to one of two parallel groups in a 1:1 fashion. Patients and data analysts will be blinded as to modalities and group allocations. Surgeons and anaesthetists will be made aware of group allocations post randomisation. Study groups and techniques of anaesthesia: Control Group: standard port site infiltration using 0.25% plain bupivacaine. The dose is calculated to 2.5mg/kg per body weight. After the appendicectomy is done, after removal of ports and deflating the abdomen, the total calculated dose volume will be infiltrated into the subcutaneous plane at the umbilicus and the other 2 ports sites . Study group: LTAP block in four points: above and below the umbilicus in both right and left sides; dose calculation 2.5mg per body weight. After the appendicectomy is done and just before withdrawing port and deflating the abdomen, the operating surgeon will advance a needle into the abdominal wall to the level of the preperitoneal space. Once the needle tip is seen, it is withdrawn slowly and gently about 0.5cm above/superficial to the transversus abdominis (TA) muscle. The surgeon then infiltrates the local anaesthetic into the plane, and the right plane is confirmed by visualising a uniform protrusion downwards of the TA muscle fibres (Doyle's bulge). Seeing a preperitoneal or muscle blister laparoscopically indicates that the infiltration is deeper to this plane, and the needle should be withdrawn more superficially. Trial duration per participant: 1 month (follow up calls 1 week and 1 month post discharge) Estimated total trial duration: It is estimated that the trial recruitment will take 1 year (based on appendicitis admission rates in both Beaumont Hospital and 3 other Dublin Hospitals). The trial will end once the final patient's follow-up is completed and assessed. Planned trial sites: Multi-site - sites Beaumont Hospital and 3 other Dublin hospitals Total number of participants planned: 172 86 Control Group 86 Study Group - TAP Block ;
