功能性内窥镜鼻窦外科应用的情况及问题

20世纪70年代,以慢性鼻窦炎/鼻息肉为主要治疗对象的功能性内窥镜鼻窦外科的创立和发展,开辟了鼻窦外科的新领域。功能性内窥镜鼻窦外科技术把鼻窦外科推向了新的阶段,使鼻窦炎临床治愈率提高到80%~90%,已成为国内外鼻窦炎外科治疗的主要方式。回顾功能性内窥镜鼻窦外科的发展历史,分析了鼻腔-鼻窦病变中应用的情况,并提出了应用中应处理好的两个问题,对准确把握功能性内窥镜鼻窦外科发展的趋势和特点具有重要的作用。     

发展微创外科技术方略的探讨

现代微创外科技术是最近20多年发展起来的一个新技术领域,代表了外科的发展方向,为传统外科技术注入了新的活力,具有广阔的发展前景。一个新技术的出现必然面临一系列新的问题,从医院管理的角度出发,对微创外科的发展策略、人才培养、资源配置、医疗安全管理和技术创新进行宏观管理是十分必要的。     

微创外科与人文关怀

微创技术是医疗技术发展的重大进步。“人文关怀”的哲学思想始终贯穿微创外科发展之中,人文关怀的哲学基础是以人为本和人本主义思想。“以人为本”体现在外科治疗过程中“以病人为主体”,促进医务人员主观能动性的发挥,有利于“以人为本”的目的实现。     

外科脓毒症：从科学认识到合理防治

脓毒症(sepsis)是一种严重威胁患者生命的外科危重症,也是诱发脓毒性休克(septic shock)、多器官功能障碍综合征(MODS)的重要原因。基于对脓毒症的病理生理的认识正不断深入,脓毒症的防治水平业已取得重要的进展。深入认识脓毒症,研究新的防治策略,实施正确的治疗,将有助于提高脓毒症的临床治疗水平。     

Predictive value of neuropsychological assessment; with regards to life expectancy among cardiac bypass surgery patients

This follow-up study to Keith et al. (2002) sought to explore relations between the cognitive, neuropsychological, and psychosocial sequelae of cardiopulmonary bypass surgery (CPB) and survival. A neuropsychological test battery including the state portion of the State-Trait Anxiety Inventory (S-STAI), reaction time, visual attention (VFA), rotor pursuit, visual spatial memory, verbal memory and paired associations (PA) was administered. PA (P < .05), VFA and S-STAI scores were related with 5–7 year survival. After the Benjamini-Hochberg method was employed to control for multiple comparisons only S-STAI scores remained significant. Results of logistic regression indicate that pre-CPB surgery scores on the S-STAI accurately predicted 5–7 year survival and mortality in 66% and 83% of cases respectively.     

Postoperative Cognitive Dysfunction Versus Complaints: A Discrepancy in Long-Term Findings

This review describes the discrepancy in findings between postoperative cognitive performance and postoperative cognitive complaints long time after an operation under general anesthesia. Shortly (from 6 hr to 1 week) after an operation a decline in cognitive performance is reported in most studies. However, long time (from 3 weeks to 1–2 years) after an operation this is rarely found although some patients are still reporting cognitive complaints. In general this kind of research is suffering from severe methodological problems (use of insensitive tests, lack of control groups, lack of parallel tests, different definitions of cognitive decline). However, these problems cannot totally explain the discrepancy in findings in the long term. Thus, there are patients who have persistent cognitive complaints long time after an operation, that cannot be measured with cognitive tests. More psychological factors such as fixation on short-term cognitive dysfunction, mood, coping style, and personality are possible explanations for these cognitive complaints in the long term. As a consequence, these factors should be a topic in future research elucidating the persistence of these cognitive complaints long time after an operation under general anesthesia.     

The acceptability of prophylactic mastectomy among lay people and health professionals: A pilot study

IntroductionWomen with certain genetic mutations have a risk of up to 85% of developing breast cancer. Bilateral prophylactic mastectomy is the most effective way to reduce risk of cancer.ObjectiveThis pilot study focuses on the acceptability of prophylactic breast surgery and examines, in a series of concrete cases, the cognitive processes by which health professionals and lay people make their judgments. This research also aims to identify the factors involved in these judgments. An additional objective is to determine whether there are groups with different patterns of responses.MethodWe recruited two samples in France, one comprising 90 lay people and the other 30 health professionals (n = 120) and asked them how acceptable it would be for a woman at a high risk of breast cancer to undergo a prophylactic surgery (mastectomy), in each of the 64 scenarios presented to them. The scenarios were all combinations of two levels of age, of marital status, of parenting status, of body appearance investment, of reconstructive surgery and also two levels of the person suggesting oncogenetic diagnosis.ResultsWe found that lay people and health professionals structured the factors in the scenarios in nearly the same way. They assigned importance to three factors: the most important one was reconstructive surgery, and then the age of the woman. The least important factor was the person who requested the genetic test. Furthermore, the age of the participants, and knowing a person who had cancer impacted the degree of acceptability assigned by participants. Being a lay person or a health professional did not have a direct impact on acceptability but influenced the integration of factors. In addition, cluster analysis showed that only a small group was opposed to mastectomy.ConclusionThis pilot study demonstrated that three factors have to be considered when judging the acceptability of prophylactic mastectomy and showed a common cognitive foundation for future discussion, at the levels of both clinical care and health policy, of the conditions under which prophylactic surgery might be acceptable.     

A self-efficacy enhancing intervention for pulmonary rehabilitation based on motivational interviewing for postoperative lung cancers patients: modeling and randomized exploratory trial

The objective of this study was to evaluate the feasibility and preliminary efficacy of a self-efficacy enhancing intervention designed for pulmonary rehabilitation based on motivational interviewing (MI) for postsurgical non-small cell lung cancer (NSCLC) patients. This study was a 2-arm pilot randomized controlled trial and was conducted in two cardiothoracic surgery departments, a tertiary hospital in Fuzhou, China. 28 postsurgical NSCLC patients were randomized to a 3 month (6 session) self-efficacy enhancing intervention based on MI or usual care (UC). Data were measured at baseline and after intervention. The MI based self-efficacy enhancing intervention group was superior to the UC group for reducing anxiety and depression, improving self-efficacy, quality of life, confrontational coping, social support and functional capacity. However, no statistically significant difference was observed in subjective well-being, posttraumatic growth, body mass index and pulmonary function between the two groups. This pilot study demonstrated the feasibility of MI based self-efficacy enhancing intervention for postsurgical NSCLC patients. A larger randomized trial would demonstrate a more rigorous test of efficacy.     

Psychological Distress Reported by Patients Undergoing Limb Reconstruction Surgery: Implications for Psychological Interventions

Limb reconstruction is an orthopaedic surgical technique designed to restore or improve functioning and appearance. The aims of the present study were to investigate levels of psychological distress in adults undergoing limb reconstruction as a result of traumatic injury, to examine which variables could account for any variations in distress during and after treatment, and to ascertain the potential relevance of psychological interventions. A cross-sectional sample of patients completed measures of psychological distress, posttraumatic symptomatology, coping, social support, pain, and disability. Self-reported levels of psychological distress and posttraumatic symptoms were high but did not tend to vary across stage of treatment, suggesting that distress is not solely attributable to limb reconstruction treatment per se but to other factors. Both medical variables (pain and mobility) and psychological variables (symptoms of trauma and coping strategies) accounted for a significant percentage of the variance in HAD scores. These results suggest that both medical and psychological interventions have potential for reducing distress and increasing well-being in an orthopaedic population who are experiencing high levels of emotional distress.
