ABSTRACT
Objective To investigate the popularization of cardiopulmonary resuscitation(CPR)knowledge and science popularization needs among urban and rural residents in Tonghai County,Yuxi City,Yunnan Province,so as to explore the establishment of an efficient and appropriate science popularization model.Methods A total of 300 residents aged 15-60 years old were selected from Tonghai County,Yuxi City,Yunnan Province using stratified and simple random sampling methods.A self-designed questionnaire was used to conduct an anonymous questionnaire survey.Results Only 20.3%of Tonghai County residents master CPR skills,and 26.2%of Tonghai County residents have never heard of CPR.There is a statistically significant difference in the awareness rate of CPR between rural residents and non-rural residents(P<0.01).There are differences in residents'age and CPR awareness(P<0.01),the age and CPR are inversely proportional.The residents have a higher willingness to perform chest compressions and mouth-to-mouth resuscitation on strangers,66.2%and 68.6%respectively.63.79%of residents have never attended relevant training.But 92.76%of the people said they were willing to participate in the relevant training when they learned the training news.Conclusion Residents in Tonghai County generally lack knowledge of CPR first aid,but the demand for first aid knowledge of residential CPR is high and the attitude towards rescue is positive.It is recommended that relevant departments increase CPR science popularization and training efforts,and popularize CPR into villages.
ABSTRACT
In recent years, the combined surgery of phacoemulsification, intraocular lens implantation, and goniosychialysis has gradually emerged as a primary and effective approach in treating primary angle-closure glaucoma with cataracts. However, with the continuous progress of medical technology, postoperative intraocular pressure control is no longer the sole pursuit. Patients increasingly aspire to achieve higher postoperative visual quality. In order to ensure that patients attain a better refractive status and higher visual quality postoperatively, it is essential to minimize the negative impact caused by primary angle-closure glaucoma. This involves personalized selection of different intraocular lenses or calculation formulas,etc. Evaluation metrics for visual quality encompass visual acuity, contrast sensitivity, higher-order aberrations, subjective perception, etc. Therefore, this paper provides a comprehensive review of postoperative refractive shift, higher-order aberrations, contrast sensitivity and their influencing factors, and the selection of intraocular lenses for patients undergoing combined surgery for primary angle-closure glaucoma with cataracts.
ABSTRACT
Objective To study the clinical efficacy of autologous cartilage following unilateral cleft lip and palate repair on correction of secondary complex deformity.Methods 17 patients with complex secondary cleft palate were enrolled in this study from December 2004 to December 2014.Correction of nasal and lip deformity and oronasal fistula were achieved at the same time.The therapeutic efficacy was evaluated after follow-up from 3 months to 2 years after operation.Results All 17 patients received satisfactory results,of which 14 patients were satisfied and three cases of general satisfaction.Conclusions Satisfactory results are received by using autologous rib cartilage to repair secondary complex deformity of unilateral cleft lip and palate.
ABSTRACT
Objective To explore the surgical method of double flag-shaped flap to correct the shortened middle part of upper lip deformity of post burn.Methods From January 2009 to December 2013,9 cases of shortened middle part of upper lip post burn deformity were corrected by double flag-shaped flap,including 4 males and 5 females who aged from 18 to 37 years.They received the surgery from 1 to 3 years after burn.The main clinical manifestations included the upper lip eversion,too short middle part of upper lip,the destruction of the normal anatomy philtrum,philtrum column deformity and poor continuity vermilion border.Results The height of the middle of upper lip of 9 patients enrolled in the experimental treatment was lengthened by 4 to 6 mm after operation,which fundamentally corrected the shortened middle part of upper lip deformity of post burn.The patients were followed up for a period of 3 months to 2 years and received satisfactory results.The operative incisions of 9 cases were primary healing,with no flap blood supply disorders,wound infection,dehiscence and other complications.Conclusions Double flag-shaped flap of the upper lip at the nostrils bottom is a simple and good effective method to correct the shortened middle part of upper lip deformity of post burn.
ABSTRACT
Objective To investigate the application of multiple dilators for excessive expansion of scalp with hair covering and integrated use of expanded flap to repair cicatricial alopecia in a large area.Methods stage Ⅰ surgery was performed as follows:multiple dilators were chosed and embedded below the galea aponeurotica of the scalp with hair covering according to the bald hair shape,size of the alopecia area.Excessive expansion was conducted for 3 to 6 months to get the extra hair scalp.Stage Ⅱ surgery was as follows:Dilators were removed and scar areas were resected,followed by combined use of sliding advancement flap,rotation flap and translocation flap to repair scalp alopecia.Resluts The postoperative effect of all patients was ideal with satisfied appearance.Conclusions Multiple dilator excessive expansion may obtain a large number of additional expansion scalp,combined by reasonable use of skin flap transfer technology,which can be used to repair the large scarring alopecia and get a good clinical effect.
ABSTRACT
Objective To explore the clinical effect of auricle reconstruction with expanded auricle posterior flap on mastoidea and auto rib cartilage bracket for repair of congenital microtia.Methods Twenty-one eligible patients with congenital auricle malformation and defect were recruited into this study and three-stage operation was performed.A 50 ml kidney-shaped expander was implanted at mastoid process area to expand skin in stage Ⅰ surgery,followed by a regular affusion to expand skin for 3 to 4 months.The average total waterflood was (80.51 ± 3.87) ml.The volume remained stable for 1 month,once up to the predetermined amount.In stage Ⅱ surgery autogenous costal cartilage was taken and carved into inverted conch shape.Auricle was reconstructed with the expanded flap to cover the auto rib cartilage bracket.The stage Ⅲ surgery was performed for details dressing of the auricle after 3 months.Results All 21 cases underwent operation successfully.Reconstructed ear auricles were similar to uninjured sides in size and shape.Both doctors and patients were contented with the auricles.Conclusions Expanded auricle posterior flap on mastoidea can cover the auto rib cartilage bracket.Autologous costal cartilage can be carved to four layers cartilage bracket that likes an inverted conch,and followed by realistic postoperative auricular shape and strong three-dimensional sense after operation.
ABSTRACT
OBJECTIVE To understand the disinfection,use and management of ventilator for the sake of regulation.METHODS By interviewing and on-site survey,we understanded the method and the process of disinfection and found out the using cycle of the ventilator system and the conditions of its management.RESULTS Among 44 ventilators 7 models were found:the management of 18 ventilators was irregular;the other 26 ventilators were disinfected by 2 kind and 4 types disinfect methods.their using cycles were unsure,their processes of disinfection were irregular.The responsibilities for the disinfection were unclear,lacking of monitoring the effect of disinfection and their management was irregular.CONCLUSIONS The disinfection of ventilator using and management must be regulated.
