Application of Enhanced Recovery After Surgery in Patients with Osteoporotic Vertebral Compression Fractures Undergoing Percutaneous Kyphoplasty.

BACKGROUND: The enhanced recovery after surgery (ERAS) program helps patients recover faster and better, postoperatively. The aim of this retrospective study was to assess the clinical effectiveness of the ERAS program after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fractures. METHODS: We enrolled patients with osteoporotic vertebral compression fracture who had undergone PKP between January 2019 and June 2021 and divided them into the control group (CG; n = 296), without the ERAS program, and the intervention group (IG; n = 306), with the ERAS program. The visual analog scale (VAS), Oswestry Disability Index (ODI), and Barthel Index scores of the 2 groups were compared on admission and 2 days and 1, 6, and 12 months postoperatively. Perioperative evaluation parameters included the mean surgery time, length of stay (LOS), and hospitalization expenses. In addition, postoperative complications were compared. RESULTS: Regarding perioperative parameters, LOS and hospitalization expenses were significantly better in IG than in CG (P < 0.001), but the mean surgery time did not differ significantly (P > 0.05). The VAS, Barthel Index, and ODI scores were significantly better in IG than in CG at 2 days and 1 month postoperatively (P < 0.001). None of the clinical effectiveness parameters (VAS, Barthel Index, and ODI scores) differed between IG and CG at 6 or 12 months postoperatively. In addition, 141 patients in CG and 56 patients in IG experienced postoperative complications, including pressure ulcers, deep vein thrombosis, nausea and vomiting, and refracture (P = 0.970, P = 0.036, P < 0.001, P = 0.002 respectively). CONCLUSIONS: For patients undergoing PKP, the ERAS program is a reliable and effective perioperative management method that can effectively reduce LOS, postoperative pain, and economic burden and promote recovery of patients.

Enhanced recovery after surgery (ERAS) relieves psychological stress in patients with osteoporotic vertebral compression fracture undergoing percutaneous kyphoplasty: an observational retrospective cohort study.

STUDY DESIGN: This is an observational retrospective cohort study. OBJECTIVE: The purpose of this study is to investigate the incidence rate of depression and anxiety and the changes in patients treated with percutaneous kyphoplasty (PKP) following ERAS protocol. The incidence of depression and anxiety is not uncommon in patients with osteoporotic vertebral compression fracture (OVCF), which affects the prognosis of surgery. Enhanced recovery after surgery (ERAS) protocols can improve the perioperative stress response of patients. MATERIALS AND METHODS: Patients were treated conventionally in 2019 as the control group (CG) (n = 281), and patients were treated according to the ERAS protocol in 2020 as the intervention group (IG) (n = 251). All patients were evaluated for depression and anxiety using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 at admission, postoperative 1 week, 1 month and 3, 6, 12 months. RESULTS: The degree of depression statistically decreased in the IG at follow-up periods (p < 0.001), and the degree of anxiety statistically decreased at 1 week (p < 0.001), 1 month (p < 0.001), 3 months (p = 0.017). Patients in the IG could soothe depression and anxiety disorders faster than patients in the CG and maintain psychological stability at the follow-up periods. The percentage of moderate or above depression in the IG was statistically fewer than in the CG at follow-up periods (p < 0.01). The odds ratio (OR) was respectively 0.410, 0.357, 0.294, 0.333, 0.327 from 1 week to 12 months. While the percentage of patients with moderate or above anxiety significantly decreased in the IG at 1 week (p < 0.001), OR = 0.528, 1 month (p = 0.037), OR = 0.309 and 12 months (p = 0.040), OR = 0.554, no differences between 3 months (p = 0.187) and 6 months (p = 0.133). CONCLUSION: PKP following ERAS protocol to treat patients with OVCF had a better effect on relieving postoperative anxiety and depression than following conventional protocol.

Single door laminoplasty plus posterior fusion for posterior atlantoaxial dislocation with congenital malformation: A case report and review of literature.

BACKGROUND: Posterior atlantoaxial dislocation (PAD) is a rare type of upper cervical spine disease. We sought to describe a unreported case of old PAD with os odontoideum (OO) and atlas hypoplasia (AH) and our unique treatment approach consisting of C1 single door laminoplasty with C1-3 posterior fixation and fusion. CASE SUMMARY: A 70-year-old male patient who suffered from progressive aggravating numbness and limb weakness for 4 years without trauma, was diagnosed with old PAD with OO and AH. The patient underwent closed reduction and C1 single door laminoplasty with C1-3 posterior fixation and fusion instead of C1 laminectomy with occipitocervical fusion. During the 3-year follow-up, he was able to walk by himself instead of using a wheelchair and with a ± 25° range of head rotation as well as a ± 10° range of flexion-extension. Three-year follow-up images showed satisfactory reduction and fusion. CONCLUSION: C1 single door laminoplasty with cervical fusion in PAD combined with spinal cord compression could be a suitable and effective surgical option. Compared with laminectomy and occipitocervical fusion, it retains more cervical range of motion, has a smaller incision and provides an adequate bone grafting space for atlantoaxial fusion.

[Effects of ketamine and alcohol on learning and memory impairment in mice].

OBJECTIVE: To study the effects of ketamine and alcohol on learning and memory in mice and its possible mechanism. METHODS: Forty mice were divided into 4 groups: normal control group, ketamine group, alcohol group, and alcohol plus ketamine group. Ketamine and alcohol were given by intraperitoneal injection and intragastric administration, respectively, 1 time per day, for 14 days. The ability of learning and memory in mice was tested by the method of step-down and Morris water maze. Acetylcholine (ACh) and 5-hydroxy tryptamine(5-HT) in mice brain tissue were analyzed for the possible mechanism. RESULTS: (1) Step-down: The treatment groups lessened the latency and added wrong times (P < 0.05). The number of errors in the combined treatment group significantly increased comparing with the single drug treatment group (P < 0.05). (2) Morris water-maze: The treatment groups prolonged the latency (P < 0.05), reduced the target quadrant activity time significantly (P < 0.05), and decreased the numbers of crossing the former platform significantly (P < 0.05). (3) Biochemical index determination: The concentrations of ACh and 5-HT in treatment groups decreased significantly (P < 0.05), showed a more decreasement comparing with the single drug treatment group. CONCLUSION: Ketamine has a synergistic effect with alcohol on learning and memory impairment in mice, which may be related to the common inhibitive effect on the ACh and 5-HT.
