Value of perioperative multimodal stratified analgesia guided by PPRS-CYMZ 2.0

Abstract

Objective To evaluate the value of perioperative multimodal stratified analgesia guided by PPRS-CYMZ 2.0. Methods One hundred and sixteen patients of both sexes, aged 16-85 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, scheduled for elective surgery in our hospital in August 2016, were included in this study and assigned into empirical analgesia group(group E, n=79)and stratified analgesia group(group S, n=73). The risk of postoperative pain was estimated by an experienced associate chief anesthesiologist based on his clinical experience, and the perioperative analgesic protocol was determined in group E. The risk of postoperative pain was assessed using the perioperative pain risk scale PPRS-CYMZ 2.0 by another experienced associate chief anesthesiologist, the risk was stratified according to the scores, and the corresponding stratified analgesic protocol was determined in group S. Visual analog scale scores and parents′satisfaction with analgesia were recorded on postoperative day 30.The requirement for preventive analgesia, total pressing times of patient-controlled analgesia(PCA)pump in 0-6 h, 6-24 h and 24-72 h periods, PCA background infusion dose and consumption of rescue analgesics were recorded.The development of adverse events during postoperative hospital stay and postoperative recovery were also recorded.Analgesia-related parameters of medical economics were calculated. Results There was no significant difference in postoperative pain risk stratification between group E and group S(P>0.05), and the majority of patients were at moderate risk.Compared with group E, no significant change was found in visual analog scale scores on postoperative day 30, PCA background infusion dose or incidence of postoperative adverse effects(P>0.05), the requirement for preventive analgesia and satisfaction scores were significantly increased in high risk patients, the consumption of rescue analgesics was decreased in moderate risk patients(P 0.05), the total pressing times of PCA pump was significantly decreased, and the direct analgesic cost per patient and total analgesic cost were decreased in moderate and high risk patients, and the first ambulation time and length of postoperative hospital stay were shortened in high risk patients in group S(P<0.05). Conclusion PPRS-CYMZ 2.0 can achieve perioperative multimodal stratified analgesia and individualized treatment. Key words: Analgesia; Pain, postoperative; Risk assessment
