Abstract

Background. Although epidural anesthesia is a Successful method for most surgical procedures on lower extremities and lower abdomen. It is not so favorable because of it's slow onset and differential sensory and motor block. In order to solve this problem effects of additive KCl (5 meq/L) into Bupivacaine 0.5 percent according to onset, intensity, duration of block and homodynamic changes during epidural anesthesia will be investigated through the present study. Methods. All the ASA I or II patients at medical centers of Isfahan university of medical sciences throughout 1378, candidate for elective Surgical procedures on lower extremities and lower abdomen with no contraindication for epidural anesthesia were Subdivided into Case (35 patients) and Control (35 patients) groups in a random manner to perform a double blind clinical trial. Epidural anesthesia applied to cases (by Bupivacaine 0.5 percent+ KCl 5meq/L) and controls (by Bupivacaine 0.5 percent). Under identical conditions, data indicating basic MAP, basic heart rate and their changes as well as the onset, duration and intensity of motor and sensory block, were obtained and recorded by the anesthesiologist. Quantitative & qualitative variables were examined by T.test and X2 test respectively. Findings. Sensory onset for cases (8.22±1.43Min) was faster than controls (11.56±1.45Min) (P
