ObjectiveTo introduce a new medical heat preservation device, and to explore the application value and effectiveness in replantation of severed fingers. MethodsThe medical heat preservation device was design, water was used as the heating medium, and temperature was set and controlled by microcomputer. Between November 2010 and January 2014, 421 cases undergoing replantation of severed fingers were divided into 2 groups. Within 9 days after operation, the medical heat preservation device was used in 210 cases (experimental group), and the conventional heat lamp was used in 211 cases (control group). There was no significant difference in gender, age, injury cause, the interval between injury and admission, injury finger side, and operation time between 2 groups (P>0.05). The vascular crisis rate, success rate of replantation of severed fingers, comfort, sleep quality, and the influence on roommates were compared. ResultsThe comfort and the influence on roommates were good in 188 cases (89.52%) and 201 cases (95.71%) in the experimental group, which were significantly higher than those in the control group (25/211, 11.85%; 145/211, 68.72%). According to Pittsburgh sleep quality index (PSQI) for sleep quality, the results were good in 105 cases, fair in 85 cases, and poor in 20 cases in the experimental group; the results were good in 45 cases, fair in 95 cases, and poor in 71 cases in the control group. Blood vessel crisis occurred in 35 cases (16.67%) of the experimental group, which was significantly lower than that in the control group (76/211, 36.02%) (P<0.05). The survival rate of replantation in the experimental group (196/210, 93.3%) was significantly higher than that in the control group (181/211, 85.78%) (P<0.05). Significant differences were found between 2 groups (P<0.05) in above indexs. ConclusionMedical heat preservation device for replantation of severed fingers can improve the comfortable degree of patients and the quality of sleep, increase the survival rate of finger replantation, and reduce the occurrence of vascular crisis after operation.
Abstract In order to investigate the pattern of the changes of blood supply of the vascular superthin skin flap during expansion, in 17 patients, under the subdermal vessel networks layer of the periauriclar area, an expander was placed, and the skin was preliminarily expanded. The changes of blood supply were found regular: When the injected fluid volume was excessive, the skin became pale or cyanotic, the skin showed congestive telangiectasis. If great care was given during the procedure, the expanded skin could pass safely through the stage of poor blood circulation. The expanded superthin skin flap were applied in auriculoplasty in 17 patients. The results included 3 failures, and 14 satisfactory.
Objective To investage the relationship among the visual loss, the disease course, and retinal circulation time in patients with central retinal artery occlusion (CRAO)． Method The data about the central vision, disease course, and results of fundus fluorescein angiography (FFA) of 99 patients (99 eyes) with CRAO were statistically analyzed. Results Between 2 days and 21 days after the occurrence of CRAO, the disease course didnrsquo;t relate to the central visual loss (Pgt;0.05). In the retinal circulation, a correlation was found between the time of fluorescein perfusion and the central visual loss (Plt;0.05) but not between the time of arm-retina circulation and the central visual loss (Pgt;0.05). Conclusion In the duration of retinal circulation, the time of fluorescein perfusion in retinal artery relates to the central visual loss; the longer the duration is, the worse the vision is.
