Associated Risk Factors Analysis For The Development Of Severe Postoperative Pain After Different Abdominal Surgery

Objective:This study analysis the association of age, sex, whether to accept patient-self-controlled pain treatment with postoperative acute pain intensity in patients with elective abdominal surgical procedures, and compared these association in different types of common abdominal surgery in order to provide patients individualized pain treatment strategies and look for some evidence-based evidence to support the therapies.Methods:We collected perioperative data from January 1, 2014 to December 31, 2014 through the Database system of our hospital surgery anesthesia.According to inclusion and exclusion criteria,we finally get number of 999 cases.The association of age, sex,whether to accept patient-self-control pain treatment with postoperative acute pain intensity was studied with multiple liner and logistic regression analyses.Results:In six surgery group of 999 clinical cases, young age, female gender, no use PCA is associated with a higher degree of postoperative pain.In each operation group, this relationships are similar.A woman's risk of severe pain occurred after the men's 2.407times(95% CI, 1.332 4.349);Age at risk of severe postoperative pain in lower level will increase 0.437 times(95% CI, 0.348 0.550);The patients without using PCA of risk of severe postoperative pain are 0.170 times than the users(95% CI, 0.071 0.407); Asoperation level increasing one level, the risk of severe pain increases 12.572 times(95%CI, 6.457 24.478);Laparotomy patients occurred more severe postoperative pain(95% CI,20.743 1170.303).Conclusion:Female sex, young age, out of use patient controlled analgesia treatment after operation, Laparoscopic surgery, higher operation level and the heavier postoperative pain(high NRS score) have linear positively regression relationship. And female gender,young age, out of use patient controlled analgesia treatment for postoperative pain management, open operation, higher operation level makes surgery patients' postoperative severe pain(NRS 7 or higher) rate is higher. Independent of the type and extent of surgery, these association constantly exist.
