The main purpose of the study is to investigate the effects of the erector spinae plane (ESP) block on managing the pain after the surgery of the lumbar spine. The study includes the patients who went through lumbar spinal surgery in the year 2017. among them, the patient data removed who has gone through secondary surgery with local anesthesia instead of ESP block. The primary outcome of this was the NRS or Numerical Rating Scale pain at different times within 2 days of the surgery. The next parameter was to calculate the intravenous fentanyl amount observed within the first 24 hours of the surgery. The study also collated data on the number of complications faced within 2 days.
The total amount of data was for 41 patients who have undergone lumbar spinal surgery during the said time period. 23 patients were given local anesthesia and the rest 18 patients have received ESP blocks apart from the general anesthesia. Therefore the study has revealed that the patients with ESP block other than normal surgery have a lesser complication in terms of pain after the surgery. It provides a postoperative analgesia for the next 24 hours from the lumbar spine surgery.
