Filter by:For a knee arthroscopy, two small incisions are made at the level of the joint line on each side of the patellar tendon. Closure of surgical incisions consists of using either nonabsorbable or absorbable sutures. Some surgeons prefer using nonabsorbable sutures due to it being easier to tie, these sutures are less likely to break prematurely, and that they elicit a minimal inflammatory response. On the other hand, some surgeons prefer using absorbable sutures due to the time savings of not having to remove the sutures at a later date and that these sutures decrease patient anxiety and discomfort. The purpose of this study is to prospectively investigate and compare patient's pain, swelling and cosmesis following knee arthroscopy surgery between patients who had their arthroscopy portals closed using resorbable sutures vs. patients who had their portals closed using nonabsorbable sutures.
Background: In emergency departments, suturing is a common procedure but often causes anxiety and pain. Virtual reality (VR) intervention has been reported as a relaxing measure. Objective: The study aims to examine the effects of VR intervention on anxiety, pain, physiological parameters, local anaesthesia requirements and satisfaction in Chinese adult patients undergoing wound closure in emergency departments in Hong Kong Hypothesis:VR can alleviate anxiety and pain experienced by Chinese adult patients undergoing wound-closure procedures, the intervention can decrease extra local anesthesia requirements and physiological parameters during the procedures, and the intervention can significantly increase satisfaction during wound-closure procedures.
IInvasive procedures such as suturing cause pain and fear in children. The high level of pain and fear of children makes it difficult to adapt to the procedure. It is a randomized controlled study planned to examine the effect of watching videos with virtual reality glasses as a distraction method while suturing in 7-12 age group children. Araştırma Acil Müdahale Odasında 01 Ekim 2022-31 Mart 2023 tarihlerinde yürütülmesi planlanmaktadır. In the collection of data; It is planned to use the Child Information Form, Wong-Baker Pain Scale, Child Fear Scale, which was created as a result of the literature review.
It is standard teaching that the top layer of sutures should be placed 3-5mm from the wound edge. However, there is lack of data regarding the most optimal placement of sutures from the wound edge for the best cosmetic outcome. The research team wish to determine if sutures placed closer to the wound edge (2mm) or farther from the wound edge (5mm) makes a difference in the cosmetic outcome of the scar.
Gingival recession is defined as the displacement of the soft tissue margin apical to the cemento-enamel junction with exposure of the root surface. It affects a broad population with presence of periodontal disease as well as periodontally healthy individuals. The occurrence of gingival recessions is age-dependent and their development begins relatively early in life. For instance, gingival recessions were noticed in more than 60% of Norwegian 20-year-olds and in more than 90% of the older population. Similar findings were reported in Brazilian and French population. In populations deprived of dental care, the occurrence of gingival recessions was even higher. Many factors have been implicated in the etiology of gingival recession, including plaque, position of the tooth in the arch and improper toothbrushing. It is difficult to see a single cause for the development of labial gingival recession. It has been demonstrated in several investigations that if left untreated, the probability of progression of the recession is high even with good oral hygiene. The indications for treatment of gingival recession are: esthetics, dental hypersensitivity, and the prevention of caries as well as further progression of the recession. Therapeutic options for recessions have been well documented with a high degree of success. Their ultimate goal is the location of the gingival margin coronal to the CEJ, with minimal probing depth and a pleasant soft tissue integration with the adjacent teeth. With such a prevalent condition, it becomes critical to discriminate when to treat these lesions and which are the anatomical and surgical characteristics that are going to determine the amount of root coverage. Regarding surgical characteristics, it has been demonstrated that the accomplishment of complete root coverage may be prejudiced by the post-surgical position of the gingival margin (the more coronal to the CEJ the greater the chance to achieve root coverage). The same author conducted a randomized clinical trial showing that the higher the flap tension, the lower the recession reduction. Another surgical factor affecting root coverage may be the use of microsurgical approaches by the use of smaller diameter sutures. According to a recently published systematic review, early suture removal (less than 10 days) can negatively affect root coverage outcome. The healing process after pedicle graft was investigated in an animal model study. The healing was divided into four different stages, the adaption stage (0-4 days), the proliferation stage (4-21 days), the attachment stage (27-28 days) and the maturation stage (1-6 months). During the proliferation stage, connective tissue invades the fibrin layer from the basal level of the flap, and after 6-10 days a layer of fibroblasts is seen in apposition to the root surface. These cells are believed to differentiate into cementoblasts at a later stage of healing. At the end of the proliferation stage, thin collagen fibers are formed adjacent to the root surface, but a fibrous union between the connective tissue and the root has not been observed. It seems logical that stabilizing the flap with sutures for a prolonged period of time during the proliferation phase would help maintain the gingival margin on a more coronal position postoperatively. On the other hand, the longer the sutures remain postoperatively, the greater the chances of plaque accumulation and inflammation affecting negatively to root coverage. The systematic review by Tatakis and Chambrone included 17 randomized clinical trials that provided an overall data of 325 single recession defects that were treated by coronally advanced flap. While they investigated time of suture removal, the studies included in this study did not account for this variable, thus leading to some bias. Moreover, different suture materials, type of suturing technique may also play an important role in the healing process. Therefore, the aim of this study is to evaluate the clinical outcome of timing suture removal regarding root coverage on coronally advanced flap.
Hookwire and microcoil are currently the most widely used localization instruments. Although their success rate is relatively high in preoperative localization attempts, they may lead to consequences that negatively affect patient outcomes, such as pain because of the metal's hardness, localization failure due to wire detachment, and the presence of permanent traces of metal and foreign bodies . To overcome these disadvantages, we designed an absorbable semi-barbed suture to localize small intrapulmonary nodules (patent number: ZL201821444387.X). The results of the previous animal experiments were satisfactory, and it is now necessary to recruit 10 patients for clinical trials.
You are being asked to participate in this study because you have a complex wound that requires treatment with negative pressure wound therapy (NPWT). NPWT is a therapeutic technique which involves the placement of a wound vacuum at the site of the wound. The wound vacuum delivers a negative pressure at the wound site through a dressing. Any fluid collected during this process is collected through a foam (sponge) underneath the dressing. This therapy helps to draw the edges of the wound together, while removing infectious material, to help promote healthy tissue growth and speed up wound healing. The purpose of this study is to determine if placing polypropylene suture (a material normally used to close wounds) between the wound and the NPWT foam would decrease pain upon removal of the sponge while allowing adequate healing of the wound.
