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).
