Brief summary

In addition to the traumatic effect of the operation, the effort to immobilize the auxiliary respiratory muscles due to pain causes a decrease in postoperative respiratory function (especially in thoracic and upper abdominal surgeries). In addition, superficial and tachypneic breathing caused by the inability of the patient to take deep breaths with pain leads to closure of small airways and increase in intrapulmonary shunts, resulting in hypoxia. Postoperative pain management is important not only to prevent pain but also to reduce pulmonary complications that may occur due to changes in lung function and to reduce mortality and morbidity by controlling the stress response. Pain after nausea and vomiting is the most common reason for hospitalization after laparoscopic surgery. Although pain in laparoscopic cholecystectomy (LC) has many components including incisional, visceral and reflected, the primary source of pain is incisional pain. A multimodal analgesic approach (NSAII, paracetamol, opioids, local infiltration, facial plane blocks and paravertebral and periparavertebral blocks) is recommended. Regional anesthesia combined with general anesthesia reduces the stress response associated with surgery and reduces the need for opioid use. Subcostal TAP Block; injection of local anesthetic between the internal oblique and transversus abdominis muscles in the upper quadrant of the anterior abdominal wall blocks the anterior cutaneous branches of the thoracoabdominal nerves. External Oblique Fascial Plane Block (EOIB); blocks both the anterior and lateral cutaneous branches of the thoracoabdominal nerves. It is performed between the 6th-7th costae. There is a cutaneous sensory block between T6-T9 in the midabdomen and T6-T10 in the anterior axillary line. The conventional method is the administration of intravenous opioids as a method of postoperative analgesia when the routine block cannot be performed due to a contraindication.
