RESUMEN
Background: A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic. Aim of this study the efficacy of topical use of collagen granules in wound healing.Methods: In this prospective study, a total of 60 patients were divided into two groups, according to type of dressing i.e. for group A patients collagen granules were used and for group B patients normal saline dressing was used. Collagen granules used for this study was Medfil II.Results: The Mean ulcer size at day 1 in group A was 16.29 cm2 with a SD of 6.07cm2. In Group B, the mean ulcer size at day 1 was 14.73 cm2 with a SD of 6.37 cm2. The Z value is 0.93 and p value is >0.5. This is comparable but statistically not relevant.Conclusions: The use of Collagen Granules dressing accelerated the rate of wound healing in chronic ulcers In this study authors found that the rate of wound healing was significantly better in using Collagen Granules but after 2 weeks.
RESUMEN
Background: Trauma is a major cause of mortality worldwide. This study is aimed at the patterns of chest trauma, their presentation and the outcome of management.Methods: A prospective study of trauma patients admitted to a tertiary care centre was carried out the clinical history, physical examination and outcome of management recorded in a predesigned proforma were analysed with SPSS 15 and the patients were followed up in the surgical department.Results: A total of 638 patients were admitted. 57 patents were identified with chest trauma, 43 (75%) were males and 14 (24.56%) were females. The age range was from 3-78 years and the most affected age was in the range of 20 to 39 years. Blunt injury constituted 82.4% while road traffic accident was responsible for 70.1%. The average time taken between accident and admission was 11 hours 12 minutes while the average duration of hospital stay was 11 days. The injury pattern mainly included rib fracture and hemopneumothorax. The mortality rate was 1.75%.Conclusions: Most patients arriving at the hospital survived, requiring general resuscitation or simple tube thoracostomy with few complications. Mortalities from trauma and cause of death at the site of accident are often not accounted for due to non-presentation to the hospital and lack of autopsy for those who present.
