RESUMO
Objective:To compare the use of continuous constant negative pressure drainage and intermittent suction mode drainage in abdominal wall angioplasty to minimize the impact of complications.Methods:From May 2017 to August 2019, the Department of Medical Cosmetology and Plastic Surgery, Wuhan Third Hospital treated 76 female patients after expanded flap repair, aged 27-35 years, with an average age of 30.5±14.2 years, and 58 female patients after abdominal wall plasty, aged 38-55 years, with an average age of 47.8±7.8 years. They were divided into intermittent negative pressure drainage group and continuous negative pressure drainage group. The negative pressure values in different intervals were set according to the type of operation. The drainage volume, drainage time, incidence of hematoma, subcutaneous effusion, flap necrosis rate, primary wound healing rate and drainage related bleeding were recorded and compared between the two groups.Results:After expanded flap repair in 38 cases, flap necrosis occurred in 1 case and hematoma in 3 cases; After abdominal wall plasty in 29 cases, flap necrosis occurred in 0 cases and hematoma in 1 case. The primary healing of incision was higher ( P<0.05), the drainage volume was larger, but the drainage time was shorter ( P<0.05), and no bleeding related to drainage was observed. The effect of monitoring drainage was positively correlated with the effect of operation. Conclusions:Continuous and constant negative pressure drainage is related to the prognosis of patients undergoing expansion flap repair and abdominal wall plasty. It is helpful to improve the effect of plastic surgery and the quality of nursing work. It is an effective method for nursing management after plastic surgery.
RESUMO
Objective To observe the clinical effect of continuous vacuum sealing drainage (VSD) in trea-ting diabetic foot and its influence on the expression of serum insulin-like growth factor(IGF1) and nitric ox-ide(NO) .Methods Sixty-eight cases of diabetic foot in this hospital from June 2014 to December 2015 served as the research subjects and randomly divided into the control group and observation group .The control group took the common wound dressing treatment ,while the observation group adopted the VSD treatment ;the clin-ical efficacies after three courses of treatment were compared between the two groups .The treatment time , number of dressing change and wound healing time in the two groups were performed the statistics .The data after completely statistics were performed the contrastive analysis ;glycosylated hemoglobin (HbA1c) ,IGF1 and NO expression levels before and after treatment were compared between the two groups .The correlation between clinical effect with the levels of IGF1 ,NO and HbA1c was analyzed .Results The clinical cure rate of the observation group was 52 .94％ ,the total effective rate was 94 .12％ ,the clinical cure rate of the control group was 35 .29％ ,the total effective rate was 67 .65％ ,and the results of curative effect evaluation in the ob-servation group was better than that of the control group ,the difference was statistically significant ( P<0 .05) .The observation group was significantly better than the control group in the treatment time ,dressing change frequency and wound healing time ,the difference was statistically significant (P<0 .05) .After three courses of treatment ,the average expression level of IGF1 and NO in the observation group were higher than those in the control group ,the difference was statistically significant (P<0 .05) .There was a negative correla-tion between the curative effect and the level of serum IGF1 and NO (r= -0 .997 ,-0 .923 ,P< 0 .05) ,and there was a positive correlation between the curative effect with the HbA 1c level(r=0 .816 ,P<0 .05) .Conclu-sion VSD has an ideal effect in the treatment of diabetic feet ,can effectively shorten the treatment time ,and has the recovery of serum IGF1 and NO expression level .
RESUMO
Introduction. With chronic obstructive pulmonary disease (COPD) exacerbations, continuous positive airway pressure (CPAP) has been used to overcome the threshold load provided by intrinsic positive end expiratory pressure and decrease the inspiratory work of breathing. In this pilot study, we observed whether a continuous negative pressure (CNP) around the thorax and upper abdomen with a shell and wrap would provide a similar level of relief in dyspnoea. Methods. In eight patients with COPD in the intensive care unit receiving CPAP, CNP was alternated twice with CPAP (30 minutes each time). We measured heart rate, respiratory rate, blood pressure, arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), pH and dyspnoea score, and asked each patient which system was more comfortable. Results. Comparing CPAP with CNP, we found no significant difference in all measured parameters except PaCO2 which was lower with CNP. Seven out of eight patients found that CNP was more comfortable. Conclusions. The CNP was similar to CPAP except CNP was more comfortable.
