Bilateral Transverse Abdominis Plane Block versus Local Wound Infiltration for postoperative analgesia in patients undergoing Laparoscopic Diversion Colostomy- A Randomized Control Study

Postoperative analgesia is important for enhanced recovery. Although laparoscopic surgeries have reduced the incision and pain in colorectal surgeries, postoperative pain is still an issue. Opioid based analgesia is generally used for pain management, however it can lead to increased incidences of post op nausea, vomiting, urinary retention, constipation etc. This study aims to compare the effectiveness of a bilateral TAP Block to opt for opioid free analgesic modalities and reduce the effects related to opioids after surgery. Patients undergoing laparoscopic diversion colostomy will be recruited for this study after obtaining for the study. This will be a randomized control trial and a double blinded study in which the patient and the primary investigator will be blinded. All the patients undergoing the surgery will be allotted a computer generated randomized number that will decide whether the patient will receive local wound infiltration or a TAP Block. The patient wil then be followed up in PACU and surgical wards. Postoperative pain intensity, opioid consumption, PEFR and occurence of any adverse events following the block and length of hospital stay will be evaluated in both arms.
