Post-operative analgesic efficacy of transversus abdominis plane block as compared to local anaesthetic infiltration at the surgical site in lower abdominal surgeries

We conducted the present study with an aim to compare the post-operative analgesic efficacy of transversus abdominis plane block (group-T) versus local anaesthetic infiltration (group-I) at the surgical site in lower abdominal surgeries. Our objectives were to assess the severity of pain (the analgesic efficacy of the two interventions) in both the study groups through the visual analogue scale (VAS) score for pain at the end of 2, 4, 6, 12, 18 and 24hrs, the time of first rescue analgesia in the form of injection tramadol 100mg i.m. required in each study groups to assess  the duration of analgesia provided by each study technique. The patients were monitored and followed up to 24 hrs post-operative to assess our outcome parameters. In our study we allocated 50 patients into two study group with 25 patients in each study group. The study population in each of the study groups was similar in terms of the demographic profile such as age, height, weight and was also similar in terms of their ASA status. The type and duration of the surgery they underwent were also comparable.
