Pre-emptif uygulanan intravenöz, spinal ve epidural morfinin erken postoperatif analjezi ve stres yanıt üzerine etkileri

Abstract

In this study, it was aimed to determine the effects of preemptive intravenous, spinal and epidural morphine on analgesic consumption, and stress response in the early postoperative period. Sixty ASA I-II patients who were undergoing lower abdominal surgery were randomly divided into three groups. Group I patients were admisnistered 5 mg iv morphine 5 minutes before induction, Grup II patients were administered 0.5 mg of intrathecal morphine 5 minutes before induction, Group III patients were administered 5 mg epidural morphine 30 min before induction of anesthesia. Induction of anesthesia, was performed with 0.1 mg kg fentanyl and 4-7 mg kgthiopental sodium. For muscle relaxation 0.1 mg kg vecuronium were given. Anaesthesia was maintained with 1-2% sevoflurane and 50% NO. Pre and postoperative hemodynamic parameters, VAS (Visual Analog Pain Scale) scores, time to first analgesic requirement, total analgesic consumption were recorded. In addition, to evaluate the stress response blood samples were taken three times before the administration of preoperative medications, preoperative 30th minute, and postoperative and 2nd hour. In our study, postoperative VAS scores between groups was significantly different at all times for the iv group and the spinal group and iv group and epidural group (P<0.05). In terms of time to first analgesic requirement, total analgesic consumption of group iv and iv with a group of spinal epidural group and the difference between groups was significant (P<0.05). Operative in terms of prolactin and ACTH between groups was significantly different at all times for the iv group and the spinal group and iv group and epidural group (P<0.05). Cortisol, glucose, and insulin levels postoperatively for 2. hour intravenous group and the spinal epidural group and iv group and the difference between groups was significant (P<0.05). As a result of preemptive spinal and epidural morphine in relieving postoperative pain and suppress the stress response was found to be effective in group iv.
