ABSTRACT
Objective:To explore an early mobilization plan for oral cancer patients after free flap reconstruction and evaluate the application effect of the plan.Methods:This study was a prospective randomized controlled trial. A total of 173 patients undergoing free flap reconstruction surgery from December 2018 to December 2021 in the second ward of Peking University School and Hospital of Stomatology were selected. The patients were randomly divided into the control group (87 cases) and the intervention group (86 cases) by cluster randomized grouping. The control group received the routine nursing plan, that was, head immobilization for 4 days after surgery, and patients performed sat up and off-bed activity on the 5th day. The intervention group received the early mobilization plan, that was, patients sat up on the 2nd day after surgery and performed off-bed activity on the 3rd day. The incidence of vascular compromise, postoperative complications, sleep time in the first 5 days after surgery, catheter removal time, hospitalization duration and expenses were compared between the two groups.Results:The incidence of postoperative pulmonary infection, the daily sleep time in the first 5 days after surgery, the time for removing nasogastric tube, trachea cannula, and urinary catheter were 7.0%(6/86), (5.0 ± 1.0) h/d, (11.8 ± 7.3) d, (6.1 ± 3.2) d, (3.6 ± 0.6) d in the intervention group, and 13.8%(12/87), (4.4 ± 1.3) h/d, (14.2 ± 5.8) d, (7.3 ± 1.7) d, (4.0 ± 0.9) d in the control group, all differences were statistically significant ( χ2 = 3.89, t values were -3.57 - -2.44, all P<0.05). There was no significant difference in the incidence of rascular compromise, hospitalization duration and expenses between the two groups (all P>0.05). Conclusions:For patients undergoing free tissue flap reconstruction, it is safe to sit up on the 2nd day and get out of bed on the 3rd day, which can reduce the incidence of pulmonary infection, improve patient sleep, and shorten the indwelling time of nasogastric tube, trachea cannula and urinary catheter.
ABSTRACT
OBJECTIVE To investigate whether electroacupuncture(EA)ameliorates abnormal trigeminal neuralgia(TN)orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1.METHODS A mouse infraorbital nerve transection model(pT-ION)of neuropathic pain was established,and EA or sham EA was used to treat ipsilateral acu-puncture points(GV20-Baihui and ST7-Xia-guan).Golgi-Cox staining and transmission elec-tron microscopy(TEM)were administrated to observe the changes of synaptic plasticity in the hippocampus CA1.RESULTS Stable and per-sistent orofacial allodynia and anxiety-like behav-iors induced by pT-ION were related to changes in hippocampal synaptic plasticity.Golgi stain-ings showed a decrease in the density of dendritic spines,especially mushroom-type dendritic spines,in hippocampal CA1 neurons of pT-ION mice.TEM results showed that the density of synapses,membrane thickness of the postsynap-tic density,and length of the synaptic active zone were decreased,whereas the width of the synap-tic cleft was increased in pTION mice.EA attenu-ated pT-ION-induced orofacial allodynia and anx-iety-like behaviors and effectively reversed the abnormal changes in dendritic spines and syn-apse of the hippocampal CA1 region.CONCLU-SION EA modulates synaptic plasticity of hippo-campal CA1 neurons,and reduces abnormal oro-facial pain and anxiety-like behavior,providing evidence for a TN treatment strategy.
