Effects of spinal anesthesia and laryngeal mask anesthesia on mood states during hemorrhoidectomy

The present study was undertaken to compare the effects of laryngeal mask anesthesia (LMA) and spinal anesthesia on mood states in patients undergoing hemorrhoidectomy. A total of 46 patients who underwent hemorrhoidectomy for grade III and IV hemorrhoids were included in this study. LMA with fentanyl plus propofol was given to 23 patients, and spinal anesthesia with bupivacaine was administered to 23 patients. Mood changes were assessed preoperatively and 2 h postoperatively with the Profile of Mood States (POMS), which consists of 65 questions that are designed to measure 6 identifiable mood states (tension, depression, anger, vigor, fatigue, and confusion). No significant differences were noted between the 2 groups in terms of baseline POMS global and subscale scores, except for scores regarding vigor. No significant mood changes were observed after hemorrhoidectomy in patients who were given LMA; however, an increase in total POMS score was reported in patients given spinal anesthesia. These findings suggest that mood score is affected by spinal anesthesia but not by LMA in patients who are about to undergo hemorrhoidectomy.
