Postoperative nausea and vomiting frequently complicate outpatient anesthesia and surgery. The duration of treatment for this complication must occasionally extend beyond discharge from the hospital. In this study, we evaluated the commonly used anti-emetic promethazine for its efficacy in the post-discharge period. Adult outpatient surgical patients who had excessive postoperative nausea and vomiting in the recovery room, or who were at risk for postoperative nausea and vomiting following discharge were given two promethazine suppositories (25 mg) for home use. All patients were contacted by our recovery room nurses on the first business day after their surgery and questioned as to their use of the suppositories and, if used, their efficacy. We found that 55 percent of patients given promethazine suppositories for home use had nausea and vomiting in the post-discharge period. Of the patients given promethazine, 89 percent used the suppositories. All of these patients reported improvement in their symptoms following use of the suppositories. None reported adverse effects from the promethazine suppositories. In conclusion, we found promethazine suppositories to be an inexpensive and efficacious treatment for nausea and vomiting in adult outpatient surgical patients following discharge from the hospital. Side-effects were minimal, and our patients voiced no complaints about this mode of therapy. We recommend this therapy for treatment of nausea and vomiting after hospital discharge following adult outpatient surgery.  相似文献

A prospective, randomised, single blind, and controlled trial of a hypnotic technique was undertaken in 39 adults with mild to moderate asthma graded for low and high susceptibility to hypnosis. After a six week course of hypnotherapy 12 patients with a high susceptibility score showed a 74.9% improvement (p less than 0.01) in the degree of bronchial hyper-responsiveness to a standardised methacholine challenge test. Daily home recordings of symptoms improved by 41% (p less than 0.01), peak expiratory flow rates improved by 5.5% (p less than 0.01), and use of bronchodilators decreased by 26.2% (p less than 0.05). The improvement in bronchial hyper-reactivity occurred without a change in subjective appreciation of the degree of bronchoconstriction. A control group 17 patients and 10 patients undergoing treatment with low susceptibility to hypnosis had no change in either bronchial hyper-responsiveness or any of the symptoms recorded at home. This study shows the efficacy of a hypnotic technique in adult asthmatics who are moderately to highly susceptible to hypnosis.  相似文献

OBJECTIVE--To assess the feasibility, safety, and efficacy of domiciliary thrombolysis by general practitioners. DESIGN--Randomised double blind parallel group trial of anistreplase 30 units intravenously and placebo given either at home or in hospital. SETTING--29 rural practices in Grampian admitting patients to teaching hospitals in Aberdeen (average distance 36 (range 16-62) miles). PATIENTS--311 patients with suspected acute myocardial infarction and no contraindications to thrombolytic therapy seen at home within four hours of onset of symptoms. MAIN OUTCOME MEASURES--Time saving, adverse events, Q wave infarction, left ventricular function. RESULTS--Anistreplase was administered at home 101 minutes after onset of symptoms, while anistreplase was given in hospital 240 minutes after onset of symptoms (median times). Adverse events after thrombolysis were infrequent and, apart from cardiac arrest, not a serious problem when they occurred in the community: seven of 13 patients were resuscitated after cardiac arrest out of hospital. By three months after trial entry the relative reduction of deaths from all causes in patients given thrombolytic therapy at home was 49% (13/163 (8.0%) v 23/148 (15.5%); difference -7.6% (95% confidence interval -14.7% to -0.4%), p = 0.04). Full thickness Q wave infarction was less common in patients with confirmed infarction receiving treatment at home (65/122 (53.3%) v 76/112 (67.9%); difference -14.6% (95% confidence interval -27.0% to -2.2%), p = 0.02). CONCLUSIONS--General practitioners provided rapid pre-hospital coronary care of a high standard. Compared with later administration in hospital, giving anistreplase at home resulted in reduction in mortality, fewer cardiac arrests, fewer Q wave infarcts, and better left ventricular function. Benefits were most marked where thrombolytic therapy was administered within two hours of the onset of symptoms.  相似文献

OBJECTIVE--To assess the effect of a programme of postoperative community surveillance on the rate of detection of wound complications after operation for inguinal hernia. DESIGN--Prospective audit of wound complications including complications recorded in case notes and those discovered by community surveillance. SETTING--Academic surgical unit of three consultant surgeons. PATIENTS--510 patients undergoing elective inguinal hernia repair between June 1985 and August 1989. RESULTS--The wound infection rate recorded in the hospital notes was 3% compared with 9% when additional information was obtained from community surveillance. Wound complications were detected in 143 (28%) patients by community surveillance compared with a complication rate of 7% in the case records for the same patients. CONCLUSIONS--Wound complications are common after clean surgery in patients discharged home early. Complication rates are a reflection not only of the standards of surgical practice but also the rigour with which they are sought. Before national comparative audit data are published the method of collection must be standardised. For short stay surgery this should include meaningful community surveillance.  相似文献

Background: Men and women communicate differently, but it is unclear whether this influences health care outcomes.Objective: Because women patients frequently choose women health care providers, we examined whether this preference was affected by communication styles. We focused on communication of disease-specific symptoms, hypothesizing that symptom agreement between women patients and women health care providers would be greater than between other patient-provider gender combinations.Methods: Patients attending outpatient clinics were recruited as part of a study of respiratory illness at 7 university-affiliated sites during 3 consecutive influenza seasons (2000–2003). Individuals aged ≥ 19 years were offered enrollment if they sought care for cold or flu symptoms at a participating study site. Patients were eligible to participate in the study if they reported any 1 of 6 symptoms: cough, runny nose, fever (subjective), muscle aches, sore throat, and/or exhaustion. Using separate questionnaires, patients and their health care providers recorded the patients' respiratory symptoms (as present or absent). Patients recorded their symptoms before visiting their health care provider, and providers recorded patient symptoms after the visit. Symptom agreement was compared using general estimating equations across all gender combinations.Results: A total of 327 patients (220 women, 107 men) and 84 health care providers (37 women, 47 men) participated in the study. Overall symptom agreement for all patient-provider gender combinations was 81.9% (95% CI, 79.6%–84.2%). For each symptom, the observed agreement significantly exceeded the agreement expected by chance alone (P < 0.001 for all symptoms except “no energy,” which was P = 0.023). The male-male pairing of patient and provider was more likely to agree on a symptom than were the other gender combinations, although not statistically significantly more so than the female-female pairing.Conclusions: In this survey of patients with respiratory illness, there was no significant difference in symptom agreement for most symptoms between the male-male and female-female patient-provider combinations. Based on these findings, symptom agreement alone does not explain why women patients select women health care providers.  相似文献

ObjectiveManaging hospitalized patients on ambulatory U-500 insulin is challenging because of limited guidance on how to safely adjust insulin doses during admission. We sought to evaluate glycemic outcomes in relation to inpatient insulin doses in patients receiving U-500 prior to hospitalization.MethodsRetrospective study of hospitalized patients on ambulatory U-500 seen consecutively from January 2015 to December 2019. Primary outcomes were inpatient hypoglycemia, hyperglycemia, and normoglycemia at different insulin dosages expressed as weight-based (unit/kg/d) inpatient total daily dose (TDD) and ratio of inpatient to outpatient TDD.ResultsWe identified 66 admissions of 46 unique patients. The median (interquartile range) body mass index was 41.0 kg/m2 (35.1, 46.8), home TDD 212 units (120, 300), and home insulin dose 1.6 units/kg/d (1.1, 2.2). The median (interquartile range) inpatient insulin dose was 0.7 unit/kg/d (0.3, 1.0) and the ratio of inpatient to outpatient TDD was 0.4 (0.2, 0.8). Hyperglycemia persisted throughout the hospitalization. For the outcomes of hyperglycemia and normoglycemia, we found no association between increased levels of insulin dosages. For the outcome of hypoglycemia, significantly higher odds were observed when non-fasting patients received an inpatient TDD that was either > 40% of their home TDD or > 0.6 unit/kg/d of insulin.ConclusionPatients on ambulatory U-500 have significant hyperglycemia during admission. Inpatient insulin doses of 40% of home TDD or ≤ 0.6 unit/kg were not associated with increased hypoglycemia risk. Further prospective studies are needed to determine effective doses in these high-risk patients.  相似文献

Although amoxicillin has long been the preferred drug for treatment of acute otitis media, resistant strains of two relatively common causal organisms have emerged, prompting a search for other antibiotics. We performed a randomized double-blind trial comparing amoxicillin and trimethoprim-sulfamethoxazole in 221 children in whom acute otitis media was diagnosed in an outpatient setting. Diagnosis was on the basis of symptoms, otoscopic examination and acoustic reflectometry. No culture specimens were taken. A research nurse, using the same methods, evaluated patients in a follow-up home visit at around 14 days and measured compliance by examination of the medicine bottle. Equal proportions of children in the two groups were cured or improved (88% and 87%). Therapeutic efficacy was related to compliance in both groups, and there were few side effects in either group. This study had statistical power of 80% to detect a difference of 15%. We conclude that trimethoprim-sulfamethoxazole can be considered a first-line antibiotic in the treatment of acute otitis media.  相似文献

The aim of this study is to evaluate the efficacy of hydroxyapatite grafts in multilevel cervical interbody fusion during the one year follow-up. A total of 86 patients with degenerative cervical disc disease underwent all together 224 cervical interbody fusion procedures in which either Smith-Robinson or Cloward type hydroxyapatite grafts were used. The surgeries included radiculopathy in 38 cases, myelopathy in 20 cases and myeloradicuopathy in 28 patients. In 65 out of 86 patients, fusion was followed by an anterior instrumentation (plating). Postoperatively, patients were followed for a mean of 15.64 (range 11-23.3) months. All patients underwent radiography to evaluate fusion and the axis curvature. Excellent clinical results (86%), described as a complete or partial relief of symptoms with full return to preop activity, were obtained in patients with radiculopathy. There were 5 grafts mobilizations and one graft fracture. Two grafts extruded in non-instrumented patients and required repeated surgery. There were other three reoperations due to the hardware problems. One year fusion rate was obtained at 86% for two-level surgery, 80.1% for three-level surgery and 74% for four-level surgery. The mean (SD) hospital stay was 3.8 (0.7) days. A hydroxyapatite cheramic can be a very effective synthetic material for multilevel cervical interbody fusion. It is characterized by a high fusion rate and a small percentage of graft-related complications, especially when fusion procedure is followed by plating.  相似文献

One hundred children, ages 6–19, who were diagnosed with attention-deficit/hyperactivity disorder (ADHD), either inattentive or combined types, participated in a study examining the effects of Ritalin, EEG biofeedback, and parenting style on the primary symptoms of ADHD. All of the patients participated in a 1-year, multimodal, outpatient program that included Ritalin, parent counseling, and academic support at school (either a 504 Plan or an IEP). Fifty-one of the participants also received EEG biofeedback therapy. Posttreatment assessments were conducted both with and without stimulant therapy. Significant improvement was noted on the Test of Variables of Attention (TOVA; L. M. Greenberg, 1996) and the Attention Deficit Disorders Evaluation Scale (ADDES; S. B. McCarney, 1995) when participants were tested while using Ritalin. However, only those who had received EEG biofeedback sustained these gains when tested without Ritalin. The results of a Quantitative Electroencephalographic Scanning Process (QEEG-Scan; V. J. Monastra et al., 1999) revealed significant reduction in cortical slowing only in patients who had received EEG biofeedback. Behavioral measures indicated that parenting style exerted a significant moderating effect on the expression of behavioral symptoms at home but not at school.  相似文献

Introduction

Lower urinary tract symptoms (LUTS), which encompass storage, voiding, and postmicturition symptoms, are highly prevalent and recognized globally. Based on a nationwide population-based database, this study tests the hypothesis that medical attendance for LUTS is associated with a subsequent increase in the number of outpatient visits and hospitalizations, with differences among medical specialties and age groups.

Methods

Participants were selected from a random population sample of approximately one million people as a representative cohort of National Health Insurance (NHI) enrollees in Taiwan. Participants had at least three outpatient service claims with a coding of LUTS during the recruitment period 2001–2004. Both the LUTS group and non-LUTS control group were monitored for subsequent outpatient visits and hospitalizations, excluding LUTS-related healthcare services, for 2 years following the index date. The results were categorized based on medical specialty and age group.

Results

The outpatient visit rates (no. per person-year) and adjusted incidence rate ratios (IRRs) (95% confidence interval (CI) were significantly higher in urology (4.51, 95%CI 4.15–4.91) and gynecology (1.82, 95%CI 1.76–1.89) for the LUTS group. They were also significantly high in other departments, including internal medicine (1.25), general practice (1.13), Chinese medicine (1.77), family medicine (1.19), surgery (1.38), and psychiatry (1.98). Similarly, the hospitalization rate (no. per 1000 person-year) and adjusted IRRs (95% CI) were significantly higher in urology (5.50, 95% CI = 4.60–6.50) and gynecology (1.60, 95% CI = 1.35–1.90), as well as in internal medicine (1.55) and surgery (1.56), but not in psychiatry (1.12). Furthermore, the IRRs differed among 3 age groups.

Conclusions

A significantly higher number of outpatient visits and hospitalizations were observed for individuals with LUTS, compared to the control group, and the effects differed with the advancement of age. This study broadens understanding of LUTS by viewing their impact on healthcare services with multiple and overlapping systems, rather than considering them exclusively as symptoms of traditional diseases of the bladder and urethra.  相似文献

The Clagett method of managing postpneumonectomy empyema was used on two patients and proved efficacious. After tube drainage (if a bronchopleural fistula is present), treatment is begun by creating a pleurostomy in a dependent site. The patient may then be cared for as an outpatient, and dressings may be changed at home. After a few months, when the pleura is clean, the pleurostomy is closed surgically and the space is filled with ¼% neomycin solution. If a fistula is present, this is closed at the same time. The treatment depends on the ability of the neomycin to sterilize any residual infection, after temporary drainage of the empyema. It makes unnecessary a major and mutilating thoracoplasty or even permanent tube drainage, which is usually difficult to manage on an outpatient basis.  相似文献

OBJECTIVE--To determine whether a booklet given to patients being discharged from hospital giving details of their admission and treatment increased their knowledge and recall when reviewed in outpatient clinics. DESIGN--Patients alternately allocated to receive a booklet or to serve as controls. Assessment by a questionnaire at first attendance at outpatient clinic after discharge. Data were collected over nine months. SETTING--One general medical and cardiological ward in a large teaching hospital and associated outpatient clinics. PATIENTS--One hundred and thirty one patients discharged taking at least one drug and scheduled to return to clinic within 12 weeks. Patients stratified by age and by the number of weeks between discharge and outpatient appointment. INTERVENTION--A booklet was given to 65 patients at discharge from the ward; 66 patients served as controls. MAIN RESULTS--Of the patients who received the booklet, 56 (86%) knew the names of their drugs, 62 (95%) the frequency of the dose, and 55 (85%) the reasons for taking each drug. The numbers in the control group were 31 (47%), 38 (58%), and 28 (42%) respectively. These differences were highly significant (p less than 0.001). Twenty six (40%) who received the booklet brought all their drugs to clinic compared with 12 (18%) control patients. Appreciably more of the first group of patients than control patients knew the reason they had been in hospital, and more of the first group indicated that they would take the correct action when their prescribed drugs ran out. Most general practitioners thought that the booklet was a good idea, that it was helpful, and that it was better than the existing interim discharge letter. CONCLUSIONS--Giving patients an information booklet at discharge from hospital appreciably increased the accuracy and thoroughness of their recall of important medical details concerning their illness and its treatment. The booklet was shown to be feasible, helpful in the outpatient clinic, and preferred by most general practitioners.  相似文献

The aim of the study was to examine a perfusion and integrity of small bowel in 60 subsequent patients during the major open abdominal surgery which lasted from 2 to 7 hours. Two samples of the intestinal mucosa were removed: at the beginning, and at the end of the surgical procedure in general anaesthesia. A mucosal injury was classified into 4 grades. pH, PCO2 and lactate level were measured in the blood samples from the arterial and mesenteric vein in one hour time intervals. The changes of intestinal mucosa were found in 31 patients (51.7%): in 19 patients (31.7%) grade 1 changes were recorded, in 10 patients (16.7%) grade 2, and in 2 patients (3.3%) grade 3. Grade 4 lesions were not recorded. There was a statistically significant correlation between grades of the mucosal damage and the surgery duration (p = 0.001). Analysis during the one hour intervals showed that there was no exact time point when the significant aggravation of the pathohistological changes in intestinal mucosa occurred. However, when patients were allocated into two subgroups with surgical procedures lasting less than 4 hours and more than 4 hours, there was a statistically significant difference in the grades of mucosal damage between subgroups (p < 0.05). More biopsies without pathohistological changes were observed in the patients whose procedure duration was < 4 hours. A significantly higher lactate concentrations in arterial and mesenteric venous blood were observed in the patients with pathohistological changes at 6 hours time point as compared to 2 hour time point in the patients without pathohistological changes (p < 0.05). During the open abdominal surgery in general anaesthesia, the length of the procedure influences the grade of the intestinal mucosa injury. Deterioration of the pathohistological findings in the intestinal mucosa correlates with high lactate blood level, suggesting that the cause of these changes may result from tissue hypoxia.  相似文献

Summary A comparison betweenParietaria pollen count and allergic symptoms of rhino-conjunctivitis in the early season was used in utilized to determine a «threshold-value» for this pollen. Clinical data were obtained from diary-cards of 34 allergic patients and pollen data from a volumetric sampling, carried out by means of a Hirst-Burkard pollen-trap. A significant correlation (r=0.98) was found between pollen count and symptom scores. Mild symptoms were registered with concentrations above 10–15 pollens/m3. Severe symptoms occurred when pollen count exceeded 80/m3/24 h., and over 90% of patients recorded symptoms. The importance of the late reactions and of the total allergenic airborne content are emphasized.  相似文献

Objective The aim was to determine the relationship and influence of different variables on the psychiatric symptomatology of older people who reside in the community, as detected by family practitioners.Design A cross-sectional and multi-centre study.Setting Twenty-eight general practices and two psychiatric practices in Huesca, Spain, from 19 primary care health centres.Subjects A sample of 324 patients aged over 65 years, representative of the older people who reside in the community in the province of Huesca.Main outcome measures Symptoms of depression (Yesavage GDS), cognitive impairment (MMSE), anxiety (GADS), psychotic symptoms, obsessive symptoms and hypochondriacal ideas (GMS) were measured by family practitioner and were detected following specific questions from the Geriatric Mental State (GMS-B) examination, following DSM-IV criteria, being defined as 'concern and fear of suffering, or the idea of having a serious disease based on the interpretation of somatic symptoms'. Sociodemographic, physical and somatic, functional and social data were evaluated. Analysis was carried out in three phases: univariate, bivariate and multivariate with logistic regression.Results At the time of the study, 46.1% of the older people studied suffered from some psychiatric symptom; 16.4% had cognitive impairment, 15.7% anxiety, 14.3% depression, 6.1% hallucinations and delusions, 7.2% hypochondriacal ideas and 4.4% obsessive symptoms. Female gender was significantly associated with depression (prevalence ration (PR) 3.3) and anxiety (PR 3.9). Age was a factor associated with cognitive impairment (PR 4.4). Depression was significantly related to severity of the physical illness (PR 61.7 in extremely severe impairment). Isolation (PR 16.3) and being single (PR 13.4) were factors which were strongly associated with anxiety; living in a nursing home was associated with psychotic symptoms (PR 7.6).Conclusions Severity of physical illness, isolation, living in a nursing home and female gender, among others, are related to psychiatric symptoms in community-residing older people identified in primary healthcare centres.  相似文献

The prevalence and recognition of depression among physically frail patients living in an urban Dutch nursing home were estimated. To patients with Mini-Mental-Status-Examination (MMSE) scores of 15 or above, the Geriatric Depression Scale (GDS) was administered (N = 80). With this screen clinically relevant depressive symptoms can be established. For diagnosing major depression according to the DSM-IV criteria, the Diagnostic Interview Schedule (DIS) (N = 57) was administered using a MMSE cut-off of 20. 49% of the respondents showed a score above the GDS cut-off (> 11), which means having clinically relevant depressive symptoms. 16% met the criteria for major depression according to DIS. Nursing home physicians recognized 39% of the patients with clinically relevant depressive symptoms and 67% of those with a major depression. Nurses recognized depressive patients slightly better but they were less specific in their judgement (more false-positive rates). We also found that in situations in which physicians and nurses had the same opinion the recognition of depression improved. Therefore it is recommended that physicians and nurses exchange their judgements on patients' mood on a regular basis.  相似文献

A retrospective study to investigate the clinical epidemiological characteristics of vertigo was carried out on 187 patients with vertigo. A clinical history for each patient was recorded precisely about the attack, frequency, and development of vertigo, its duration, intensity, and the accompanied symptoms including the risk factors for cerebrovascular disease, etc. All the patients were subjected to physical examination with special attention to neurologic systems and Dix-Hallpike maneuver, computed tomography/computed tomography–angiography (CT/CTA) and MRI scan were performed when necessary. Majority of the patients in this study suffered with posterior circulation ischemia (59.89%) and benign paroxysmal positional vertigo (16.04%). Other ailments that affected these patients included migraine, Meniere’s disease (1.6%), sudden hearing loss (1.07%), vestibular neuronitis, multiple sclerosis, acute viral encephalitis, meningioma, neurosis, posttraumatic vertigo, acute myocardial infarction (0.53%), and neurosis (14.97%). It appeared that in comparison to younger patients the elderly population is likely to be more susceptible to vertigo. Vertigo attacks patients with various diseases, which pre-dispose the patients to this disease. Presentation of vertigo can be clinically diagnosed in most cases of patients suffering from posterior circulation ischemia.  相似文献

The records were reviewed of 406 patients with carcinoma of the large bowel who had been treated at the Middlesex Hospital during 1958-62. Of these patients, 180 were followed up regularly in this hospital after radical surgery, and from six months to 15 years after operation they were seen 2319 times; 71 developed a recurrent carcinoma but, of these, 41 recurrences (58%) were diagnosed at times other than those of the patients'' routine outpatient appointments, although they were being regularly reviewed. Only one patient with recurrence appeared to have been cured by further surgery. For the present, adequate education of patients in the symptoms of early recurrence, with instruction to return if any of these develop, is likely to be more effective than the unsatisfactory and time-consuming routine follow-up still used in many hospitals.  相似文献

A history of respiratory or other allergic symptoms during the Christmas season is occasionally obtained from allergic patients and can be related to exposure to conifers at home or in school. Incidence and mechanism of production of these symptoms were studied. Of 1657 allergic patients, respiratory and skin allergies to conifers occurred in 7%. This seasonal syndrome includes sneezing, wheezing and transitory skin rashes. The majority of patients develop their disease within 24 hours, but 15% experience symptoms after several days'' delay. Mould and pollen studies were carried out in 10 test sites before, during and after tree placement in the home. Scrapings from pine and spruce bark yielded large numbers of Penicillium, Epicoccum and Alternaria, but these failed to become airborne. No significant alteration was discovered in the airborne fungi in houses when trees were present. Pollen studies showed release into air of weed, grass and tree pollens while Christmas trees were in the house. Oleoresins of the tree balsam are thought to be the most likely cause of the symptoms designated as Christmas tree allergy.  相似文献
