Objective:To compare the effects of enhanced heat preservation strategies and conventional heat preservation strategies in the operation room on body temperature, coagulation function, and myocardial injury in patients with cervical spinal cord injuries.Methods:A retrospective cohort study was conducted to analyze the clinical data of 160 patients with cervical spinal cord injuries admitted to Second Affiliated Hospital of Xi′an Jiaotong University and Affiliated Honghui Hospital of Xi′an Jiaotong University from February to October 2022, including 82 males and 78 females, aged 38-64 years [(50.6±8.7)years]. Injured segments included C 3 in 19 patients, C 4 in 33, C 5 in 39, C 6 in 38, and C 7 in 31. According to American Spinal Injury Association (ASIA) classification, 10 patients were classified into grade A, 83 grade B, 39 grade C, and 28 grade D. All the patients underwent cervical laminoplasty, decompression and bone graft fusion surgery. According to different heat preservation strategies intraoperatively, the patients were divided into conventional heat preservation group ( n=80) and enhanced heat preservation group ( n=80). The body temperature changes before surgery, at 2 hours during surgery, immediately after surgery, at 2 and 24 hours after surgery were compared between the two groups. The changes of coagulation function before surgery and at 4 hours after surgery were compared between the two groups, including the prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). The incidence of myocardial injury and the number of patients with myocardial injury measured by the indicators of cardiac troponin I (cTnI) and high-sensitivity cardiac troponin T (hs-cTnT) at 48 hours after surgery. Before surgery and at 14 days after surgery, ASIA classification was used to evaluate the neurological functions, including sensory and motor functions between the two groups. The incidence of cardiovascular events at 12 months after surgery were compared between the two groups. Results:A total of 145 patients were followed up for 12-18 months [(15.7±1.6)months]. At 12 months after operation, there were 7 patients in the enhanced heat preservation group were lost to follow-up, compared to 8 patients in the conventional heat preserration group. There was no statistically significant difference in body temperature between the two groups before surgery or at 24 hours after surgery ( P>0.05). At 2 hours during surgery, immediately after surgery and at 2 hours after surgery, the body temperature was (36.90±0.12)℃, (37.00±0.06)℃, and (37.16±0.06)℃ in the enhanced heat preservation group, which were significantly higher than those in the conventional heat preservation group [(36.56±0.03)℃, (36.74±0.08)℃, and (36.84±0.08)℃] ( P<0.01). The serum levels of PT, TT and APTT were not significantly different between the two groups before surgery ( P>0.05), while they were (13.1±1.2)seconds, (19.2±1.1)seconds, and (36.2±3.3)seconds in the enhanced heat preservation group at 4 hours after surgery, which were significantly lower than those in the conventional heat preservation group [(14.3±1.0)seconds, (20.2±1.1)seconds, and (38.7±3.4)seconds] ( P<0.01). The incidence of myocardial injury in the enhanced heat preservation group was 5.0% (4/80) at 48 hours after surgery, which was lower than 12.5% (12/80) in the conventional heat preservation group ( P<0.05). With cTnI as the indicator of myocardial injury, there were 2 patients [2.6%(2/76)] with myocardial injury in the enhanced heat preservation group, which was much lower than 8 patients [11.8%(8/68)] in the conventional heat preservation group ( P<0.05). With hs-cTnT as the indicator of myocardial injury, 8 patients [10.5%(8/76)] in the enhanced heat preservation group experienced myocardial injury, similar with 10 patients [14.7%(10/68)] in the conventional heat preservation group ( P>0.05). There were no statistically significant differences in the ASIA scores of the sensory and motor functions between the two groups before surgery and at 14 days after surgery ( P>0.05). The incidence of cardiovascular events at 12 months after surgery in the conventional heat preservation group was 27.8% (20/72), which was significantly higher than 9.6% (7/73) in the enhanced heat preservation group ( P<0.01). Conclusion:For patients with cervical spinal cord injuries, compared with conventional heat preservation strategies, the enhanced heat preservation strategies in the operating room can improve the patients′ core body temperature and coagulation function, and significantly reduce the incidence of myocardial injury and cardiovascular events.

Objective:To explore the repairing effects of 3D-printed nano-β-tricalcium phosphate (β-TCP) scaffolds loaded with vancomycin and bone morphogenetic protein-2 (BMP-2) for seawater -soaked tibial bone defects in rabbits. Methods:A total of 27 male New Zealand White rabbits were assigned to the normal group using a random number table method, with each group consisting of 9 rabbits. The rabbit tibial bone defect model was created using the osteotomy surgical method. Eight hours after operation, the wounds in the control group and seawater group were immersed in seawater for 2 hours, and those in the normal group were not immersed. After an observation period of 5-7 days, no significant redness or purulent discharge was observed in the wound appearance, then debridement was performed followed by corresponding implantations: the control group with gelatin sponges loaded with vancomycin and BMP-2, and the other two groups with 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2. After filling the bone defects with the respective materials, all groups underwent layer-by-layer suturing of the wound, followed by disinfection with iodine and injection of gentamicin to prevent infection. The affected limbs were then immobilized using a plaster cast. The affected limbs were imaged using anteroposterior X-ray at 4, 8 and 16 weeks after operation, and the repair effects were evaluated using the Lane-Sandhu X-ray scoring system. At 16 weeks after operation, the bone defect tissues were collected for HE staining to observe bone tissue growth.Results:At 4 weeks after operation, the Lane-Sandhu X-ray score in the control group was significantly lower than that in the normal group [(2.8±1.1)points vs. (1.1±0.9)points] ( P<0.05), and that in the seawater group [(2.2±1.0)points] was not significantly different from those in the other two groups (all P>0.05). At 8 weeks after operation, the seawater group [(6.1±0.9)points] and the control group [(2.8±1.0)points] exhibited lower Lane-Sandhu X-ray score compared to the normal group [(8.2±1.0)points] (all P<0.05), and the seawater group showed a higher score compared to the control group ( P<0.05). At 16 weeks after operation, the control group [(3.8±1.0)points] exhibited a lower Lane-Sandhu X-ray score compared to the normal group [(10.0±1.3)points] and the seawater group [(9.3±1.2)points] (all P<0.05), while no significant difference was noted between the latter two ( P>0.05). At 16 weeks after operation, histological observations revealed varying degrees of bone tissue formation in three groups, with the normal group showing the best bone defect repair effect, followed by the seawater group. Conclusion:The 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2 are effective for the treatment of seawater -soaked bone defects, which can promote bone tissue repair.
