| Objective To explore the risk factors of mental disorders after spinal surgery in elderly patients. Methods 348 elderly patients undergoing spinal surgery from January 2011 to June 2016 in our hospital were analyzed retrospectively, with 164 males and 184 females, aged 62-93 years, with an average age of (71.02±5.31) years. Sex, age, operation time, intraoperative blood loss, dosage of narcotic drugs, other systemic diseases and postoperative mental disorders of the patients were recorded. Results There were 83 cases (23.85%) of postoperative mental disorders in 348 patients. There was significant difference in age, operation time, intraoperative blood loss and complications between the patients with and without postoperative mental disorders (P＜0.05 for all). Age ≥80 years (OR=1.260, P=0.004), the operation time ＞90 min (OR=4.477, P＜0.0001), the intraoperative blood loss ≥400 ml (OR=4.292, P=0.005), concomitant hypertension (OR=2.422, P=0.002), concomitant diabetes mellitus (OR=2.757, P=0.027), and concomitant cerebrovascular disease (OR=14.510, P=0.037) were the risk factors of mental disorders after operation. Conclusion Age, operation time, intraoperative blood loss and complications (primary hypertension, diabetes mellitus, cerebrovascular diseases) are independent factors of mental disorders in elderly patients after spinal surgery. We should actively treat the complications, shorten the operation time, and control the intraoperative blood loss so as to avoid the occurrence of postoperative mental disorders. |
