Abstract:
Objective:To observe the effect of goal-oriented management of continuous monitoring of regional cerebral oxygen saturation (rSO 2) on early postoperative neurocognitive disorders (PND) in elderly spinal surgery patients. Methods:From November 2018 to July 2019, 60 patients undergoing posterior lumbar interbody fusion in the Second Hospital of Shanxi Medical University were selected and randomly divided into control group and intervention group, 30 cases in each group. RSO 2 was recorded before anesthesia induction (T 0), 10 min after anesthesia induction (T 1), 10 min after prone position (T 2), 10 min after spinal decompression (T 3), 30 min after spinal decompression (T 4) and 10 min after extubation (T 5); The basic value of rSO 2, the minimum value of rSO 2 (rSO 2min), the average value of rSO 2 (rSO 2mean) and the maximum percentage of decrease of rSO 2 (rSO 2% max) were recorded. When rSO 2 <55% or rSO 2% max >10% and the duration was longer than 15 s, the intervention group took measures such as adjusting head position, adjusting blood pressure, increasing FiO 2 and respiratory parameters, increasing P ETCO 2 until rSO 2 returned to the required range; The control group did not interfere with the intraoperative rSO 2. Neuropsychological tests were used to evaluate the cognitive function of the two groups 7 days after operation. The patients were followed up 30 days after operation with the revised cognitive function telephone questionnaire (TICS-M). The incidence of postoperative neurocognitive impairment (PND) was recorded. The perioperative data and postoperative adverse reactions of the two groups were recorded. Results:At T 3 and T 4, the rSO 2 of the intervention group was significantly higher than that of the control group ( P<0.01), the intraoperative rSO 2min and rSO 2mean of the intervention group were higher than the control group, and the rSO 2%max was lower than the control group ( P<0.05). The incidence of PND 7 days after surgery, extubation time, postanesthesia care unit (PACU) stay time, hospital stay and postoperative adverse reactions in the intervention group were lower than those in the control group ( P<0.05). There was no significant difference in the incidence of PND 30 days after operation between the two groups ( P>0.05). Conclusions:The goal-oriented management of rSO 2 can reduce the incidence of early postoperative PND in elderly spine surgery patients, which is conducive to the rapid recovery of patients after surgery.
