Pain after thoracotomy is the most severe pain experienced by the patient. Good pain control after the operation provides comfortable respiration and reduces the development of chronic pain and complications.

we aimed to compare SAPB with IBregarding postoperative visual analog scale (VAS) scores and analgesic consumption in patients undergoing thoracotomy operation.

Patients who underwent thoracotomy operation in our hospital between May 2016 and June 2017 were examined. A retrospective evaluation was made of the data that was retrieved from the records of a total of 49 patients aged 18-75 years, ASA I-III, who were applied with Intercostal (IB) or Serratus anterior plane(SAPB) for a thoracotomy operation. The patient information was retrieved from the patient records and anesthesia block forms. The data were examined in respect of age, sex, height, weight, ASA, operation type, operating time, the amount of postoperative analgesic consumption, VAS at 1.,2.,4.,6.,12.,24. hours and complications (atelectasis, nausea, vomiting, hypotension and bradycardia).

Statistical analysis was performed using the SPSS program for Mac, version 17.0 (SPSS,Chicago,IL). Descriptive statistics are presented as mean and SD, and as the number of cases (n) and the corresponding percentage (%) for nominal variables. T tests were performed for normally continuous variables. The Mann-Whitney U test was used for non-parametric variables. A value of p < 0.05 was considered statistically significant.
