Comparison of epidural anesthesia and TAP block for pain relief in colorectal surgery

Objective. To compare the use of epidural anesthesia and TAP block during colorectal surgery, to evaluate the analgesic effect, the effect on hemodynamic parameters and postoperative recovery of patients. Materials and methods. The study was conducted during colorectal surgery in 18 patients who were divided into two groups. In group A, the epidural space was catheterized, in group B – the lateral TAP block was performed bilaterally under ultrasound control. Intraoperative and postoperative hemodynamic parameters, pain level on a visual analog scale at 1, 6 and 24 hours after surgery, and the incidence of adverse reactions were evaluated. Results. Patients in group A had lower intraoperative systolic blood pressure and heart rate at 1, 6, 12 hours after surgery, and they were more likely to use norepinephrine. The level of pain was lower 1 hour after the intervention in group B, but higher in 6 and 12 hours. Patients in group B felt more comfortable after surgery and became more active. Both groups did not differ in the length of stay in the intensive care unit. Conclusions. TAP block can be an alternative to epidural anesthesia during colon surgery
