Acute appendicitis which is the most common cause of acute abdominal pain, is an acute inflammation of appendix vermiformis. Appendectomy operations can be performed as laparoscopic and open surgery. Addition of opioids to intrathecal local anesthetics to improve the quality of preoperative analgesia is an increasingly used method in recent years. The aim of this study is to compare bupivacaine-fentanyl and bupivacaine-alfentanil which are used intrathecally to create motor and sensory block. 50 volunteer patients who were diagnosed as appendicitis by laboratory tests and clinical diagnostic methods in general surgery clinic and classified as American Society of Anesthesiologists Classification I-II (ASA Class I-II) aged between 20-60 years scheduled for laparoscopic appendectomy operation, were included in this study. The patients were randomly assigned into two groups, Group I and Group II. Patients received spinal anesthesia with either 10 mg heavy bupivacaine (2 cc)+25 mcg fentanyl (0.5 cc) intrathecally (Group I, n=25) or 10 mg heavy bupivacaine (2 cc)+250 mcg alfentanil (0.5 cc) intrathecally (Group II, n=25).

Inclusion Criteria:

• Individuals who will undergo laparoscopic appendectomy operation and volunteer to participate in the study were included.

Exclusion Criteria:

• Individuals who meet the criteria but are not volunteers
• Previously underwent appendectomy
