Clinical Trial – Subarachnoid Bupivacaine in Obese Patients Undergoing Cesarean Delivery
This study evaluates the effect of subarachnoid hyperbaric bupivacaine on mean arterial blood
pressure (MAP) of pregnant patients with obesity undergoing cesarean section half of the
patients will receive subarachnoid hyperbaric bupivacaine at a dose of 5 mg while the other
half will receive a dose of 10 mg
Clinical Trial – Use of Intrathecal Analgesia in Appendectomy
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).
Clinical Trial – Intrathecal Additives to Prevent Post Spinal Shivering in Transurethral Prostatectomy
Spinal anesthesia is the technique of choice in transurethral prostatectomy.However,one of
the common complications of spinal anesthesia is shivering which is even exaggerated in
patients undergoing transurethral prostatectomy.this high incidence is most probably caused
by sympathetic block and use of large amount of irrigation fluid during surgery.There are two
methods to reduce shivering.Previous studies showed that intrathecal fentanyl is an
appropriate method to reduce shivering.Intrathecal dexamethasone could reduce shivering by
regulating immune responses.
