The Effect of Local Anesthetic Infiltration or Erector Spina Plan Block on Stress Hormone Response

Laparoscopic cholecystectomy is one of the most common operations in abdominal surgery. Abdominal and shoulder pain are frequently seen in patients in the postoperative period. Laparoscopic surgery is considered the gold standard in abdominal surgery because of its low cost, less postoperative pain, early mobilization, and short hospital stay. Effective analgesia in the postoperative period; It is of great importance in terms of acceleration of recovery, prevention of atelectasis, reduction of endocrine and metabolic stress response, reduction of thromboembolic complications, protection of cognitive functions, prevention of chronic pain development, and reduction of hospital stay . Intravenous paracetamol, NSAID/cyclooxygenase-2 selective inhibitors, opioids, local anesthetic infiltration in the port area, intraperitoneal local anesthetic insufflation or plan blocks can be used in the treatment of postoperative pain after laparoscopic cholecystectomy. In laparoscopic cholecystectomy operations, the results of pain reduction and analgesic consumption in incisional local anesthetics are variable. Operation, tissue trauma, anesthesia, drugs given to the patient, type of anesthesia, blood loss, temperature changes and pain cause postoperative stress response . In various surgeries, regional anesthesia for post-operative purposes, plan blocks, infiltration or insufflation methods were found to suppress the stress response. In this study, the investigator aimed to compare the effects of local anesthetic infiltration at the wound site and erector spine plane block on stress hormone response and postoperative analgesia in patients who will undergo laparoscopic cholecystectomy surgery.
