RESUMEN
Objective:To investigate the effect of applying foam dressing combined with self-made adhesive penile hood fixation in children after circumcision.Methods:A total of 101 cases of children who received circumcision from January to December 2020 in the urology department of the People′s Hospital of Xuancheng City were selected. The patients were randomly divided into experimental group (50 cases) and control group (51 cases). In the experimental group, the incision was wound with foam dressing combined with the self-made adhesive penile hood fixation method, while in the control group, the incision was wound with the conventional sterile gauze dressing combined with the simple plastic basket fixation method.The postoperative incision bleeding, prepuce edema, incision pain, incidence of complications and the satisfaction of the children′s family members on postoperative dressing and fixation were compared between the two groups.Results:The incidence of prepuce edema in the experimental group was 88.00% (44/50), 12.00% (6/50), 0, which in the control group was 43.14% (22/51), 45.10% (23/51), 11.76% (6/51), and the difference between the two groups was statistically significant ( Z= -4.80, P<0.05). In the experimental group, pain score at 24 hours after operation and at the time of dressing change were 3.50 ± 1.04, 2.48 ± 0.54, respectively, which were lower than that of the control group 5.31 ± 1.36 and 7.12 ± 0.97, and the difference between the two groups was statistically significant ( t=7.53, 29.66, all P<0.05). The incidence of postoperative infection and urinary retention in the experimental group were 0 and 2.00% (1/50), respectively, which were lower than 7.84% (4/51) and 7.84% (4/51) in the control group, and the difference between the two groups was statistically significant (Fisher′s exact probability method, P<0.05). The degree of family satisfaction in the experimental group was 96.00% (48/50), which was higher than that in the control group (78.43%, 40/51), and the difference between the two groups was statistically significant ( χ2=6.95, P<0.05). Conclusions:The application of foam dressing combined with pasting penile hood after circumcision can reduce the degree of foreskin edema, pain and the incidence of complications, and improve the satisfaction of the children′s family members.

Objective:To explore the application effect of the modified early warning score (MEWS) in the allocation of nursing human resources per shift in ICU.Methods:A total of 470 critically ill patients admitted to the ICU of Xuancheng People′s Hospital from January to December 2019 were selected as the experimental group. In each shift, the nursing leader conducted MEWS score for patients in the ward, and assigned nurses at the corresponding level according to the MEWS score. A total of 346 critically ill patients admitted to ICU from January 2018 to December 2018 were selected as the control group. The head nurse assigned nurses daily according to clinical experience.The incidence of accidental events, nurse error events and medical satisfaction were compared between the two groups.Results:The incidences of accident and nurse error in ICU patients in the experimental group were 5.96% (28/470) and 12.13% (57/470), respectively, which were lower than those in the control group [11.56% (40/346) and 17.92% (62/346)]. The difference between the two groups was statistically significant ( χ2=8.19, 5.37, both P<0.05). The satisfaction degree of the experimental group was 98.63 ± 1.06 and 95.96 ± 1.84, respectively, which were higher than that of the control group 92.13 ± 2.17 and 90.43 ± 2.91, and the difference between the two groups was statistically significant ( t=7.62, 8.56, both P<0.05). Conclusions:Using MEWS score to guide the allocation of nursing human resources in each shift of ICU is helpful to reduce the incidence of accidental events in ICU patients and the incidence of nurses′ errors, ensure patient safety and improve medical satisfaction.
RESUMEN
Objective To evaluate the etiology, pathogenesis, clinical manifestation, imaging features, treatments and factors related to prognosis of acute spinal spontaneous hematoma.Methods The clinical data of 38 patients with acute spinal hematoma treated in our hospital from 2011 till now were analyzed retrospectively.Duration of follow-up was 6 months.The factors influencing the prognosis were analyzed.Results Acute epidural hematomas (n=29) were much more common than subdural (n=5), subarachnoid (n=1) and intramedullary (n=3).Most hematomas were located in the cervical and thoracic vertebra regions.The etiology of acute spinal spontaneous hematoma was unknown in most patients.Twenty-nine patients were dealt with surgical intervention and 9 patients were treated conservatively.After 6-month follow up, recovery rate measured by JOA score in patients of spinal injury ASIA level A and B was (51.26 ±38.97), and level C, D and E was (80.33 ±25.83), P<0.05.Recovery rate in patients with hematoma discovered in less then 24 hours treated with surgical decompression was (64.79 ±36.10), and that in those with hematoma present over 24 hours was (34.54 ±30.17), P<0.05.Conclusions Acute spinal hematoma always caused by unknown etiology, and usually manifests itself in a sudden onset of pain and neurological deficits.The early diagnosis mainly depends on MRI.Patients presenting with severe neurologic dysfunction or showing signs of progressive deficit should have immediate surgical intervention. The status of neurological deficits before surgery and the length of interval between onset and surgical intervention are associated with recovery.
RESUMEN
Porous titanium is a kind of new biomaterial. After being implanted into the bone, the ingrowth of the bone was demonstrated. This ingrowth of bone tissuse was thought to be beneficial to fixation of a prosthesis and filling of a bone cavity.In this study, the porous sample was abtained from sintered amorphous titanium powder, with the mean size of pores larger than 150? in diameter, and the porosity in the range of 45-47%. It was implanted into the femurs of rabbits and dogs, and specimons were taken for examination 2, 4, 6 and 12 weeks after operation.It was shown that the shear strength of the samples at the implant bone surface was 7.51kg/cm2 2 weeks after surgery. It was demonstrated that bone tissue had begun to grow into the meshwork 2 weeks after surgery, and deeper penetration was seen after 4 weeks. Scanning electron microscopy was done to show the appearance of bony growth into the meshwork. Bony growth was verified by x-ray diffraction scan analysis for calcium. Bone ingrowth could be seen in the majority of the interstices of the meshwork 12 weeks after surgery. Bone lacuna and tubules could be seen when stained with silver nitrate. The deepest penetration of bone ingrowth was 1400?. There was no obvious tissue reaction or formation of fibrous membrane.The use of the porous material may help to prevent loosening of a prosthesis. It is believed that porous titanium we used possesses the characteristics that a porous material should possess. Further research should be done to ascertain its clinical usefulness.
