ObjectiveTo explore the effect of spiritual care on improving the psychological stress levels of relatives of patients with terminal cancer. MethodsDuring January 2013 and January 2014, 220 relatives of patients with terminal cancer were selected. Convenience sampling method was adopted to select 100 relatives out of 190 who were agreed to be participated in the investigation, who were divided into the trial group and the control group with 50 in each according to the random alphabet method. The control group was given routine care and psychological counseling, and the trial group was given spiritual care intervention additionally. Before intervention, all of the individuals in both of the two groups should conduct the questionnaire of general demographic data, caregiver stress scale, fatigue rating scale, quality of life scale (QLS), social support scale (SSS), and relatives stress scale (RSS). ResultsAfter one month's intervention, caregiver stress scale score (52.14±4.75), fatigue rating score (76.75±8.69), RSS score (15.71±3.97), SSS score (22.59±2.22), the QLS score (66.9±7.5) in the trial group were significant better than those in the control group (P < 0.05). After intervention, all the scores in the trial group were significant better than whose before the intervention (P < 0.05). ConclusionFor the relatives of the patients with terminal cancer, spiritual care can reduce the occurrence rate of stress and fatigue, relieve the psychological stress level, and improve the social support and quality of life.
Objective To confirm the difference between internal and external pressure of cervical esophageal and to discuss the relations between cervical esophageal pressure difference with the formation of cervical anastomotic leakage. Methods In the present study, 12 New Zealand white rabbits were used. We applied a pressure transducer to describe the variation of pressure of intrathoracic, thoracic esophagus, cervical esophagus and upper esophageal sphincter during resting and cough. Pressure value was recorded and read through MD3000 system. And the difference between each point was analyzed. Results The pressures resulting from the cough induced were significantly higher in intrathoracic than in thoracical esophagous (10.2±0.6 cm H2O vs. 36.7±1.0 cm H2O), exhibited significantly higher in upper esophageal sphincter and thoracic esophagous than in cervical esophageal (7.5±0.2 cm H2O vs. 12.0±0.4 cm H2O, vs. 10.2±0.6 cm H2O). Conclusion Cervical anastomotic leaks are affected by many factors.And the most notabe one is the constant pressure from inside-out around cervical anastomotic.
OBJECTIVE To investigate the effect of the endoexpander pressure of continuous and constant pressure expansion on the drug permeability. METHODS The expanders were divided into two groups, the normal expansion and the continuous and constant pressure expansion (4.6 kPa). Each expander was filled with 0.2% Metronidazole, then the expanders were immersed wholly in normal saline and sealed totally. At several intervals over 72 hours, the surrounding saline was sampled and the drug concentration of the sample was measured respectively. RESULTS Both groups were permeable to the Metronidazole and the concentration outside the expander would reach the effective concentration in 48 hours. The drug concentration of the continuous and constant pressure expansion was higher than that of the normal one and there was significant difference between the two groups (P lt; 0.01). CONCLUSIO The endoexpander pressure in continuous and constant pressure expansion can enhance the drug permeability. In view of this, in the course of continuous and constant pressure expansion, 0.2% Metronidazole can be used to prevent and control the infection.
Objective To investigate the indication, approaches andpreventionof complications in treatment of female stress urinary incontinence(SUI) with tension-free vaginal tape (TVT). Methods From September 2003 to December 2004, 40 cases of female stress urinary incontinence were treated, including 8 cases in association with cystocele or rectocele and 1 case in association with uterine prolapse. They ranged from 30 to 70 years in age with an average of 56.3years. The disease course was 1.42 years(7.2 years on average). All patients received TVT. In the patients suffering from uterine prolapse and cystocele or rectocele, butterfly-shaped mesh patch was applied. Results All patients achieved satisfactory results.The complications included slight dysuria(2 cases),vesical perforation(1 case) and pelvic hematoma(1 case) and cleared up after treating. All cases were followed up 1 to 15 months and the results were satisfactory. No urinary incontinence and no dysuria reoccurred. Conclusion TVT is effective for SUI.
ObjectiveTo explore the effects of small dose and low pressure lavage on gastrointestinal hemorrhage induced by acute poisoning. MethodsWe collected the clinical data of all the patients diagnosed as gastrointestinal hemorrhage induced by acute poisoning treated between January 2011 and December 2012. The patients were divided into two groups: control group and treatment group, according to the different treatments they underwent. The control group received traditional treatment only, while the treatment group received small dose and low pressure lavage as well as the traditional treatment. After recording the ages, poisoning dose, pretreatment time, shock and complications, we evaluated the risk of death by calculating ROCKALL scores. ResultsThe differences of ages, sexes, and poisoning dose between these two groups were not significant. However, the death rate in high and middle risk patients of the treatment group was significantly lower than that of the control group (P<0.05). ConclusionThe small dose and low pressure lavage can improve the prognosis of the gastrointestinal hemorrhage induced by acute intoxication.
Objective To compare the effect of two types of intermittent pressure on formation of pressure ulcer in rabbit hind l imbs and to investigate the mechanism of gradually changed intermittent pressure produced by waves bed in the prevention of pressure ulcer. Methods Gracil is (3 cm2) in both hind l imbs of 12 adult Japanese white rabbits were randomlyloaded with gradually changed intermittent pressure (50-160 mm Hg, 1 mm Hg=0.133 kPa) and sustained pressure (100 mmHg) serving as the experimental group and the control group, respectively. The experiment was terminated after 4 cycles, and a single cycle included 2 hours of compression and 30 minutes of compression-release. Blood velocity of hind l imbs and blood perfusion of wound were detected by bidirectional doppler blood flow detector and laser doppler perfusion imaging detection system before compression and at every 10 minutes in compression-release period of each cycle (0, 10, 20 and 30 minutes). After the termination, gross observation of the wound was conducted, pathomorphological changes of tissues from compressed area were observed by HE staining, and contents of NO, malondialdehyde (MDA), and superoxide dismutase (SOD) in muscle tissue were measured using colorimetry method. Results No significant difference was evident between two groups in terms of blood flow velocity before compression (P gt; 0.05); the blood flow velocity of two groups decreased significantly at 0 minute in every compressionrelease period of each cycle, and no significant differences were noted between two groups (P gt; 0.05); the blood flow velocity of theexperimental group was higher than that of the control group at 10, 20 and 30 minutes (P lt; 0.05). No significant difference was noted between two groups in terms of wound blood perfusion before compression (P gt; 0.05); the wound blood perfusion of two groups decreased significantly at 0 minute in every compression-release period of each cycle, and no significant differences were noted between two groups (P gt; 0.05); the difference between two groups was not significant at 10 minutes in the first cycle (P gt; 0.05), and the experimental group was higher than the control group at 20 and 30 minutes in the first cycle (P lt; 0.05). In the following 3 cycles, the recovery of perfusion in the experimental group was faster than that of the control group (P lt; 0.05). Gross observation showed the experimental group had less effusion than the control group. The experimental group had intact cutaneous appendage, less inflammatory cell infiltration, and no obvious ulcer formation, whereas the control group had obvious skin ulcer, depletion of cutaneous appendage, and more inflammatory cells infiltration. Significant differences were noted between two groups in terms of NO, MDA, and SOD content (P lt; 0.05). Conclusion Gradually changed intermittent pressure can maintain the blood perfusion of tissue, reduce ischemia-reperfusion injury and cell apoptosis, and prevent the formation of pressure ulcer.
ObjectiveTo explore the psychological pressure in Intensive Care Unit (ICU) nurses and the sources of their pressure. MethodWe investigated the ICU nurses in West China Hospital with a self-designed psychological pressure questionnaire from March to September 2013. ResultsThe total stress level of ICU nurses was 2.89±0.86. The top five sources were low salaries and welfare benefits (3.37±0.61), high frequency of night work (3.31±0.88), wide need of knowledge (3.22±0.41), heavy workload (3.20±0.80) and chronic fatigue syndrome (3.19±0.75). ConclusionsGreat psychological pressure exists in ICU nurses. We urgently need effective approaches to relieve the stress of ICU nurses in order to improve the efficiency and quality of nursing service.
