Effect of Erector Spina Plane Block on Cost of Laparoscopic Cholesistectomy Anesthesia

Erector spina plane (ESP) block has analgesic efficiency and its popularity is growing steadily. ESP block forms a sensorial block by local anesthetic infiltration between the musculus erector spina and facia. ESP block given to participants undergoing laparoscopic cholecystectomy for postoperative opioid analgesia resulted in a decrease of postoperative pain scores in the first 24 h. Due to increases in health expenditure, cost control is becoming more and more important. Cost-effective studies are important in healthcare economics. Inhaled anesthetics used in anesthesia departments account for about 20% of total anesthetic agents. Local anesthetic agents decrease the minimum alveolar concentration (MAC) value of inhaled agents. And also in perioperative and post operative period, the anesthetic management often need to be supported with opioid drugs. The investigators think that ESP block has analgesic effects and decreases the consumption of inhalation agents. The investigators aim to investigate the cost-effectiveness of ESP block in anesthetic applications in laparoscopic procedures.
