ABSTRACT
Objective:To investigate the effect of care bundles on prevention of nasal medical device-related pressure injury in patients with nasotracheal intubation undergoing oral and maxillofacial surgery under general anesthesia.Methods:This was a retrospective study. Using the convenient sampling method, patients with a surgical time more than 4 hours and a surgical grade of 3 or 4, with nasotracheal intubation undergoing oral and maxillofacial surgery under general anesthesia from Hospital of Stomatology, Sun Yat-sen University were selected. A total of 96 patients from July to December 2019 were in the control group, and 99 patients from July to December 2020 were selected as the observation group. The control group was treated with routine nursing measures, the observation group was subjected to a nursing care bundle. The incidence of nasal pressure injury was observed after the operation, 24, 48, 72 hours after the nasotracheal intubation was removed, and patients′ satisfaction score was compared.Results:The incidence of nasal pressure injury in the control group was 6.25% (6/96). None of the patients in the observation group had any pressure injury, which was significantly lower than the control group (Fisher exact probability method, P=0.013). The satisfaction scores in the observation group was significantly higher than that in the control group (26.88 ± 1.94 vs 24.71 ± 3.33), the difference was statistically significant ( t=-5.54, P<0.01). Conclusions:The care bundle can effectively prevent the occurrence of nasal pressure injury in patients undergoing oral and maxillofacial surgery with nasotracheal intubation and improve patient satisfaction.
ABSTRACT
Objective To investigate the effects of plaque staining test on periodontal health of middle-aged and elderly patients with dental implants. Methods Ninety patients with dental implants were included in the study and divided into test group (n=45) and control group (n=45) by using random digit table. In the test group, the patients were all instructed with both routine health education and dental plaque dyeing education, while the control group received routine health education only. The plaque index (PLI) and gingival index (GI) were assessed at months 1 and 6 after implant restoration. Results One month after dental implantation, there were no significant differences in PLI and GI between the two groups (P>0.05), while 6 months after the implantation, the differences in PLI and GI between them were significantly different ( P<0 . 01 ) . Conclusion The plaque dyeing technology applied in the oral health education to elderly patients with dental implants can reduce plaque index and gingival index so that their periodontal health is enhanced.
ABSTRACT
ObjectiveTo discuss two fixation methods of nasotracheal intubation on the occurrence of nasal pressure sores in patients with maxillofacial surgery.MethodsThree hundred cases of patients under general anesthesia more than 4 hours with the nasal endotracheal intubation were randomly assigned into control group and experiment group with 150 cases in each group.In control group,medical tape was used to fix the endotracheal tube to dorsum,wrapping around the joint of endotracheal tube and threaded pipe.In experiment group,Mepilex foam dressing was used to wrap over the bend of endotracheal tube,with gauze covering the joint of endotracheal tube and threaded pipe before fixing the endotracheal tube to dorsum.Finally,the occurrence of pressure sores from the end of surgery to postoperative 1day were compared between the two groups.ResultsThe incidence of patients with first stage pressure sores was 4.7% in control group while none in experiment group.The incidence of nasal pressure sores was much lower in experiment group than that in control group (P<0.05).ConclusionsThe use of Mepilex foam dressing can reduce the pressure and friction between the endotracheal tube and the dorsum,which effectively prevents nasal pressure sores caused by endotracheal intubation.Therefore when having surgery with nasal general anesthesia and nasotracheal intubation and lastsing over 4 hours,the use of application covering the bend of endotracheal tube can prevent nasal pressure sores.
ABSTRACT
In this study ,we analyzed the genetic characterizations and propagation paths of measles viruses prevalent in Ningbo ,China from 2004 to 2013 .Measles viruses were isolated from throat swab specimens from 2004 to 2013 ,and 450 bp fragments of C terminus of nucleoprotein (N) gene were amplified by RT-PCR .Sequence analysis was conducted of all 31 virus strains ,and then compared with other measles virus strains published in GenBank .Results showed that all the 31 measles virus isolates belonged to genotype H1 ,6 strains (one strains in 2004 and 5 ones in 2005) belonged to H1b subtype ,and others be-longed to H1a subtype .Compared the 31 strains to the China 93-4 and China 94-7 ,the homology of 450 bp fragments of C ter-minus of nucleoprotein (N) gene were 97 .1%-100% and 96 .7%-100% ,respectively .The homology of 450 bp fragments of nu-cleotide and nucleotide (amino acids) compared with S191 were 81 .9%-92 .4% and 87 .2%-90 .6% ,respectively .It’s suggested that genotype H1 measles virus circulated in Ningbo from 2004 to 2013 ,and H1a was the predominant epidemic strain ,and H1b strain was existed as well .There are five different transmission chains of H1a subtype caused measles co-circulations in Ning-bo .
ABSTRACT
Objective To evaluate the functional and aesthetic disturbance of patients treated with lingual orthodontic surgery and to investigate the key points of laboratory procedure and clinical treatment of lingual orthodontic deformity. Methods A total of 30 cases of Angle class Ⅰ with moder-ate crowding were selected. They were equally divided into two groups: one group was treated using lingual brackets, and the other using conventional labial brackets. Each patient completed a four-part survey right after the bracket placing and 7, 28, 56 days after the treatment. The differences of tongue-lip-cheek soreness, eating and speech difficulties and aesthetic problems were evaluated be-tween two groups. Lateral cephalograms were analyzed at the start of the treatment and the end of the overall treatment. Results Speech difficulties of lingual orthodontics were significantly greater (P<0.01) than that in the labial orthodontics group in the first week of the treatment. Eating difficulties were greater (P<0.01) in the lingual orthodontics group by 28 days, whereas aesthetic problems were greater in group using labial appliance than group lingual appliance. Conclusions In the first two months of the orthodontic treatment, eating and speech difficulties are the most severe problems for the lingual group. Lingual orthodontics offers important aesthetic advantages over labial orthodontics, and it will be one of the development directions of current orthodontics.
