I. INTRODUCTION
RESEARCH QUESTION:
What is the postoperative analgesic effects between intrathecal morphine and intrathecal tramadol in patients aged 18-50 years old after lower abdominal surgery at De La Salle University Medical Center?
SIGNIFICANCE OF THE STUDY:
Spinal anesthesia is commonly used for lower abdominal surgeries. It has become a popular practice to add opioids in the local anesthetics being used for spinal anesthesia. This is being done to enhance and prolong the intra-operative and post-operative analgesia. Morphine and tramadol are opioids that can be used for this purpose, but there are no specific guidelines on the dosage of these specific opioids to be added in the local anesthetic. Furthermore, the incidence of side effects of these different opioids is still controversial.
This will be a retrospective study to review, improve and innovate the multimodal analgesic techniques used in lower abdominal surgery with the study period of 9 months from June 2013 to February 2014 at DLSUMC. This study aims to compare the efficacy and duration of analgesia of Morphine 0.2 mg versus Tramadol 20 mg added to 0.5% 20 mg hyperbaric Bupivacaine after lower abdominal surgery, to improve the quality of analgesia post-operatively and to avoid complications of local anesthetics used in spinal anesthesia.
