[Hemodynamic effects of genu-pectoral position during the surgery of lumbar disk herniation: spinal anesthesia versus general anesthesia].

Spinal anesthesia (SA) for lumbar disk surgery in the genu-pectoral position (GP) has been proposed as an alternative to general anesthesia (GA). This study compares the haemodynamic effects of GP in two groups of patients undergoing either SA (n = 43) or GA (n = 40). Mean arterial pressure (MAP) and heart rate (HR) were recorded before and after GP.

[Lumbar disk herniation with surgical option: general versus local anesthesia. Round table].

Lumbar disc hernia is a frequent pathology whose treatment remains essentially surgical. The type of anesthesia can be general anesthesia with intubation and controlled ventilation, both mandatory due to the position, peridural or spinal anesthesia. The usual position is knee-chest position which impairs circulation and ventilation if some precaution are not taken.

Reviews and summaries of research related to AACN 1980 research priorities: clinical topics.

This article reviews and summarizes the research conducted following publication of the 1980s American Association of Critical-Care Nurses' clinical research priorities. Original research conducted on the clinical priority topics between 1981 and 1991 was included. Review articles, doctoral dissertations, theses and abstracts were excluded unless judged to provide important information on the topic.

Determining AACN's research priorities for the 90s.

The American Association of Critical-Care Nurses completed a three-phased process of priority identification for critical care nursing research. In phase 1, a 78-item survey was generated following a comprehensive review of potential research topics. In phase 2, approximately 1000 critical care nurses rated each item on the survey for importance to critical care nursing.

Contributors to cardiac invalidism after acute myocardial infarction.

Cardiac invalidism is a term used repeatedly in the literature during the past few decades, but little attention has been given to studying the variables contributing to this phenomenon. Data were collected from 111 patients with first acute myocardial infarction. Patients were visited at home 1 month and 4 months after hospital discharge.

Clinical safety and cost of heparin titration using bedside activated clotting time.

Objective: To evaluate the clinical safety of heparin titration and the procedural cost of anticoagulation measurement using bedside low-range activated clotting time.

Design: Quasi-experimental study using data gathered through retrospective record review.

Setting: Coronary care, medical intensive care and telemetry units of a community hospital.

Does overprotection cause cardiac invalidism after acute myocardial infarction?

Objective: To determine if overprotection on the part of the patient's family and friends contributes to the development of cardiac invalidism after acute myocardial infarction.

Design: Longitudinal survey.

Setting: Nine hospitals in the southwestern United States.

Moving beyond: a generative philosophy of science.

Philosophies of science are perhaps the most covert yet significant forces influencing the direction of change within disciplines. Although the era of logical positivism has waned for many disciplines, newer philosophies may not be satisfactory, especially for the applied disciplines. This article describes an alternative philosophy of science with special significance for nursing.

The relationship of education to critical thinking ability and values among nurses: socialization into professional nursing.

Exposure to faculty is assumed to positively influence critical thinking ability and professional values; therefore, faculty must be assumed to be superior in these characteristics. As a first step toward testing these assumptions, this study used a cross-sectional survey technique to compare critical thinking ability and values in ADN-prepared (n = 32) and BSN-prepared (n = 32) registered nurses, nursing faculty (n = 32), and sophomore college students (n = 32) beginning a baccalaureate degree program in nursing. The critical thinking ability of faculty was not significantly higher than that of sophomore nursing students when the influence of age was controlled statistically.

Effect of nitroglycerin ointment placement on headache and flushing in healthy subjects.

The purpose of this study was to determine the effect of site of nitroglycerin ointment placement on headache and flushing in healthy subjects. Twenty-six subjects were given two doses of nitroglycerin ointment 3 hr apart in a randomly assigned arm-chest sequence or chest-arm sequence. Subject reports of headache and flushing using the visual analogue scale were recorded.

[Intravascular volume expansion and intravenous nimodipine in the treatment of cerebral vasospasm after surgical treatment of intracranial aneurysm].

The advantage of calcium antagonist on cerebral arterial spasm during the peri-operative period has been recently demonstrated. However, the role of volemia and cardiac output in the pathogenesis of arterial spasm seems predominant. The basal hemodynamic profile of 17 patients operated for an intracranial aneurysm was investigated.

[Interaction of nimodipine and isoflurane in surgery of intracranial aneurysm].

A moderate controlled hypotension has been performed with isoflurane in the presence of nimodipine (4 mg.h-1) on ten patients anesthetized for cerebral aneurysm clipping. The administration of both drugs induced a dose-dependent hypotension secondary to the reduction of the systemic vascular resistance without impairment of cardiac index.

Social support and psychological adjustment to chronic coronary heart disease: operationalization of Johnson's behavioral system model.

No comprehensive theory of social support and psychological adjustment to chronic illness such as coronary heart disease (CHD) exists. This article reviews the literature on social support and adjustment to CHD from the perspective of Johnson's behavioral system model. It is argued that the quality of social support or nurturing is the major factor predicting cardiac crippled behaviors or dependency following myocardial infarction (MI).

Effect of nitroglycerin ointment placement on the severity of headache and flushing in patients with cardiac disease.

Fifty-six patients with cardiac disease participated in a study to determine the effect of site placement on patient reports of headache and flushing after topical nitroglycerin ointment placement. Nitroglycerin was placed on the upper arm, chest, and pelvis in random order. Approximately 30 minutes after application, patients were asked to evaluate their headache and flushing using a visual analogue scale.
