Randomized Controlled Trial Comparative Study
Impact of epidural analgesia on quality of life and pain in advanced cancer patients.
Patients with advanced cancer often experience chronic postoperative pain and poor quality of life. The objective of this study was to determine if epidural self-controlled analgesia reduced the incidence of chronic pain and improved the quality of life when compared with intravenous self-controlled analgesia. A total of 50 patients diagnosed with advanced cancer who received analgesia treatment were randomly divided into two groups, epidural self-controlled analgesia group (EA group, n = 26) and intravenous self-controlled analgesia group (IA group, n = 24). ⋯ The VAS in the EA group was significantly lower than that in the IA group (p < .05), and the Karnofsky score in the EA group was significantly higher than that in the IA group (p < .05). Moreover, patients treated with EA felt more satisfied and experienced fewer complications than those with IA (p < .05). The epidural self-controlled analgesia may greatly improve the quality of life and relieve the pain in patients with advanced cancer.

Occupational asthma (OA) and work-exacerbated asthma (WEA), collectively known as work-related asthma (WRA), have been recognized as the most prevalent work-related lung diseases in the industrialized world. OA is asthma caused by workplace conditions, and is subdivided into sensitizer-induced (allergic) OA and irritant-induced (nonallergic) OA. WEA is asthma that is made worse, but was not initially caused, by workplace conditions. ⋯ If possible, diagnostic assessment should also include objective evidence with functional and immunologic testing. Treatment and prevention of onset or worsening of WRA can be highly effective and typically include both optimal medical management (generally the same as for non-WRA) and, importantly, avoidance of sensitizer or irritant exposures that caused or exacerbate the asthma. In most cases of OA, prognosis is better with cessation rather than reduction of exposure, and this may require substantial changes in the workplace environment or change of job or even profession.

Hypoxic pulmonary vasoconstriction (HPV) is critically important in regionally heterogeneous lung diseases by directing blood toward better-oxygenated lung units, yet the molecular mechanism of HPV remains unknown. Transient receptor potential (TRP) channels are a large cation channel family that has been implicated in HPV, specifically in the pulmonary artery smooth muscle cell (PASMC) Ca and contractile response to hypoxia. In this study, the authors probed the role of the TRP family member, TRPV4, in HPV. ⋯ TRPV4 plays a critical role in HPV, potentially via cooperation with TRPC6.

ReviewOptimal technique for deep breathing exercises after cardiac surgery.
Cardiac surgery patients often develop a restrictive pulmonary impairment and gas exchange abnormalities in the early postoperative period. Chest physiotherapy is routinely prescribed in order to reduce or prevent these complications. Besides early mobilization, positioning and shoulder girdle exercises, various breathing exercises have been implemented as a major component of postoperative care. ⋯ Arbitrary instructions are given, and recommendations on performance and duration vary between hospitals. Deep breathing exercises are a major part of this therapy, but scientific evidence for the efficacy has been lacking until recently, and there is a lack of trials describing how postoperative breathing exercises actually should be performed. The purpose of this review is to provide a brief overview of postoperative breathing exercises for patients undergoing cardiac surgery via sternotomy, and to discuss and suggest an optimal technique for the performance of deep breathing exercises.

Molecular weight and molar substitution are more important in HES-induced renal impairment than concentration after hemorrhagic and septic shock.
Clinical studies have raised concerns about the safety of 6% hydroxyethylstarch (HES) 130/0.42, but the pathomechanisms of this renal impairment remain unknown. To evaluate the effects of different HES concentrations, molar substitutions and molecular weights in HES-induced renal impairment, we used a porcine two-hit model that combined haemorrhagic and septic shock. ⋯ In this porcine two-hit shock model, treatment with 0.9% NaCl, HES 130/0.42 or HES 200/0.5 led to a similar maintenance of haemodynamic values. Despite this similar maintenance of the haemodynamic values, volume replacement with 6% and 10% HES 200/0.5 led to an accumulation of HES, higher colloid osmotic pressure and significantly reduced renal function after haemorrhagic and septic shock. These facts support the presumption that not the concentration but the degree of substitution and the molecular weight play a decisive role in HES-induced renal impairment.
