Study on Nursing Effects of Liposuction and Volume Reduction Surgery for Lymphedema Perioperative Nursing Care

Objective:To study the nursing effect of liposuction and volume reduction in the treatment of lymphedema during the perioperative period.Method:A total of 68 patients treated with liposuction volume reduction surgery for pseudo-lymphedema of lower limbs admitted from May 2019 to May 2020 in a tertiary hospital in Xi’an,Shaanxi Province were selected,and they were divided into observation group and control group by random grouping method.There were 34 cases in each group.The control group took routine care during the perioperative period,while the observation group performed full care during the perioperative period.The complication rate and pain degree of the two groups were compared.Results:The complication rate of the study group was 5.88%,while that of the control group was 26.67%.Compared with the study group,the complication rate was significantly higher than that of the control group,and the gap was statistically significant(P>0.05).The pain scores of patients in the study group were significantly lower than those in the control group at 3 and 6 days after surgery,and the gap was statistically significant(P>0.05).Conclusion:Lymphedema should be taken care of during the perioperative period of liposuction and volume reduction,which can effectively reduce the occurrence of pain and complications.It is worthy of extensive clinical promotion.

Effect of lung volume reduction surgery on early function of lung and pulmonary hemodynamics in COPD

Objective To evaluate the effects of lung volume reduction surgery (LVRS) on early lung function and pulmonary hemodynamics in severe chronic obstructive pulmonary disease (COPD). Methods 31 patients with severe COPD underwent LVRS, bilateral LVRS in 11 patients and unilateral in 20 patients. The results of lung function (FEV1, RV, TLC), arterial blood gas analysis (PAO2, PACO2 ) and color Doppler echocardiography (CD,CI,FS,EF,PAP) were analyzed before and 3 month after LVRS in 26 cases. Results FEV1, RV and TLC were improved significantly after surgery ( P 【 0. 01). PaO2 increased (P 【 0. 05 ) and PaCO2, decreased postoperatively (P 【 0. 01). According to the Doppler echocardiography, there were no statistic differences in cardiac functions (CO, CI, FS, EF, and PAP) between pre- and post-operation. The 6-minute-walk-distance in 26 patients was (227 ± 88) m, significantly increased after surgery. Conclusion LVRS is effective in the treatment of patients with severe COPD. 3 months after operation, the

Mid-term effects of lung volume reduction surgery on pulmonary function in patients with chronic obstructive pulmonary disease

Background Now lung volume reduction surgery （LVRS） has become one of the most effective methods for the management of some cases of severe chronic obstructive pulmonary disease （COPD）. We evaluated the mid-term effects of LVRS on pulmonary function in patients with severe COPD. Methods Ten male patients with severe COPD aged 38-70 years underwent LVRS and their pulmonary function was assessed before, 3 months and 3 years after surgery. The spirometric and gas exchange parameters included residual volume, total lung capacity, inspiratory capacity, forced vital capacity, forced expiratory volume in one second, diffusion capacity for CO, and arterial blood gas. A 6-minute walk distance （6MWD） test was performed.Results As to preoperative assessment, most spirometric parameters and 6MWD were significantly improved after 3 months and slightly 3 years after LVRS. Gas exchange parameters were significantly improved 3 months after surgery, but returned to the preoperative levels after 3 years. Conclusions LVRS may significantly improve pulmonary function in patients with severe COPD indicating for LVRS. Mid-term pulmonary function 3 years after surgery can be decreased to the level at 3 months after surgery. Three years after LVRS, lung volume and pulmonary ventilation function can be significantly improved, but the improvement in gas exchange function was not significant.

Clinical study of simultaneous lung volume reduction surgery during resection of pulmonary or esophageal neoplasms

Background If the emphysema lesions are not symmetrical, unilateral lung volume reduction surgery （LVRS） can be carried out on the more severe side. The aim of this research was to evaluate the feasibility and effects of LVRS performed simultaneously with resection of pulmonary and esophageal neoplasms. Methods Forty-five patients with pulmonary neoplasm and 37 patients with esophageal neoplasm were randomly assigned to group A or group B. In group A, LVRS was performed simultaneously on the same side as thoracotomy. In group B, only tumor resection was performed. The nonfunctional lung area was determined by preoperative chest computed tomography and lung ventilation/perfusion scan. The lung volume removed was about 20% to 30% of the lobes on one side. Preoperative and postoperative indexes including pulmonary function testing variables, arterial blood gas analysis variables, dyspnea scale, 6-minute walk distance, etc., were compared between the groups. Results There were no surgical deaths in this study. The postoperative forced vital capacity in 1 second, PaO2, PaCO2, dyspnea scale, and 6-minute walk distance were improved significantly in group A, whereas these indexes did not change or decreased slightly in group B. Conclusions For tumor patients who have associated emphysema, simultaneous LVRS not only increases the chance of receiving surgical therapy, but also improves the postoperative quality of life of the patient. LVRS has expanded the surgical indication for tumor patients.

Short- and long-term outcomes of lung volume reduction surgery

In 1957, Brantigan applied lung volume reduction surgery （LVRS） to the treatment of emphysema. In 1995, Cooper reused this operation and obtained remarkable benefit in patients with chronic obstructive pulmonary disease （COPD）. Although there are still some doubts about the effect of LVRS, in the past 10 years, a lot of clinical information approved that LVRS can give benefit to more than 70% of COPD patients. At present, a series of researches in long-term investigation and function evaluation such as NETT have got elementary affirmative conclusion about some disputative problems.
