The Effect of Adding to Lidocaine Morphine or Tramadol During Brachial Plexus Blockade onPostoperative Analgesia

BAC K G R O U N D The aim of the study was to compare the effect of postoperative analgesia between the morphine and tramadol added lidocaine groups in brachial plexus blockade. M ET H O D S Seventy-five patients (ASA I-II) scheduled for arm and forehand surgery were included in the study. The surgery was performed under general anaesthesia and brachial plexus blockade was performed at the end of surgery for postoperative analgesia. The patients were randomly allocated into three groups. In group L (n=25), 40 ml lidocaine 1%, in group M (n=25), 40 ml lidocaine 1% with 5 mg morphine, and in group T (n=25) 40 ml lidocaine 1% with 50 mg tramadol were given. Visual analog scale (VAS) was used for pain evaluation and motor blockade scale was used to evaluate motor blockade at 5, 10, 15, 30, 60 minutes and 2, 3, 4, 5, 6, 12 and 24. hours. Respiratory and hemodynamic changes were also recorded at the same intervals. R E S U LTS There was no statistical difference between the groups by means of demographic, hemodynamic and respiratory parameters (p>0.05). All groups mean VAS scores were lower than three during the postoperative period (p>0.05). No motor blockade, side-effects or complications were detected. CO N C L U S I O N S It was concluded that the usage of lidocaine and opioids together during brachial plexus blockade was not effective than lidocaine alone on postoperative analgesia for minor surgical procedures.
