Abstract
During septorhinoplasty, many different surgical procedures are employed to bring the nose to the desired shape and solve breathing complaints. As a matter of course, intraoperative pain response occurs due to these procedures. With this study, the authors aimed to evaluate the intraoperative pain formed during septorhinoplasty surgery with numerical values and to determine which stage of surgery is more painful. Between April 2019 and March 2020, a total of 30 female patients who were planned to undergo septorhinoplasty were included in this prospective study. Standard anesthesia and analgesia were applied to all patients. During surgery, state entropy measure was utilized to evaluate the depth of anesthesia, and Surgical Pleth Index was employed to evaluate the response of the central nervous system to pain "nociception." The age of the patients ranged from 18 to 42 years (average, 25.3 ± 6.1 years). The average value of state entropy recorded during the surgery for all patients was found to be 45.43 ± 5.37. The mean beginning Surgical Pleth Index value recoded from all of the patients was 23.4 ± 8.84 compared with the beginning value; the values recorded during periost dissection, lateral osteotomy, and lower turbinate lateralization were statistically significantly higher (P < 0.005). Although sufficient depth of anesthesia and standard protocol of analgesia were applied, pain response was found to be significantly higher at some procedures during septorhinoplasty. The authors think that increasing the depth of anesthesia during these procedures will increase the comfort of this operation by inhibiting pain response.
