The prevalence of peripheral intravenous cannulae and pattern of use: A point prevalence in a private hospital setting

Aims and objectives

To determine the prevalence and pattern of use of peripheral intravenous cannulae in hospital wards.

Background

Peripheral intravenous cannulae are commonly used in acute health care to directly access the bloodstream for the administration of medications, intravenous fluids and blood products. Peripheral intravenous cannulae are associated with multiple adverse events including hospital‐acquired bloodstream infection, thrombophlebitis and pain/discomfort. Administration of intravenous fluids is associated with impaired mobility and nocturia which may increase falls risk in the older people.

Design

Observational, point prevalence study.

Methods

Three private hospitals comprising a total of 1,230 beds participated in the study. Nurses recorded the presence of a peripheral intravenous cannulae, duration of insertion, state of the dressing and whether the peripheral intravenous cannulae was accessed in the previous 24 hr and for what purpose. Nurses were also asked whether they would replace the peripheral intravenous cannulae should it fail.

Results

Approximately one‐quarter of patients had a peripheral intravenous cannulae, the majority of which had been present for <24 hr. The major use of the peripheral intravenous cannulae was antibiotic administration. Administration of intravenous fluids occurred in the presence of normal oral fluid intake. Nurses would not replace one‐third of peripheral intravenous cannulae in the event of failure. A majority of patients were at increased falls risk, and one‐third of these were receiving intravenous fluids.

Conclusions

There is room for improvement in the utilisation of peripheral intravenous cannulae, particularly in removal and associated use of intravenous fluids. Alternative strategies for medication administration and timely switch to the oral route may reduce the risks associated with intravenous fluids.

Relevance to clinical practice

Vigilance is required in the use of peripheral intravenous cannulae. Consider transition of medication administration to oral intake where possible to minimise risks associated with the use of invasive devices and increased fluid intake.     

Phenomenology as research method or substantive metaphysics? An overview of phenomenology's uses in nursing

In exploring phenomenological literature, it is evident that the term ‘phenomenology’ holds rather different meanings depending upon the context. Phenomenology has been described as both a philosophical movement and an approach to human science research. The phenomenology of Husserl, Heidegger, Gadamer, and Merleau‐Ponty was philosophical in nature and not intended to provide rules or procedures for conducting research. The Canadian social scientist, van Manen, however, introduced specific guidelines for conducting human science research, which is rooted in hermeneutic phenomenology and this particular method has been employed in professional disciplines such as education, nursing, clinical psychology, and law. The purpose of this paper is to explore the difference between the phenomenological method as described by van Manen and that of other philosophers such as Husserl, Heidegger, Gadamer, and Merleau‐Ponty. In so doing, the author aims to address the blurred boundaries of phenomenology as a research method and as a philosophical movement and highlight the influence of these blurred boundaries on nursing knowledge development.     

Feasibility and morbidity of reversal of Hartmann''s

OBJECTIVE: Reversal of Hartmann's is a major surgical procedure and associated with substantial morbidity and mortality. METHOD: This study retrospectively analysed the data at a single centre over an eight-year period to assess the clinical results and morbidity of reversal of Hartmann's. RESULTS: One hundred and ten Hartmann's procedures were performed during the period. Only 66 (61%) of patients had a reversal. Advanced age and comorbidity were the primary reasons for not reversing. Complications among the 66 patients (36 males and 30 females) who underwent reversal occurred in 26 (41%). There were no deaths. Patients who underwent reversal were ASA 2 (60%), ASA 3 (25%) and ASA 4 (4.6%). Univariate analysis demonstrated a significant association between complications following reversal and ASA grade (P =0.01), and hypertension (P = 0.03) There was no correlation between the patient variables and anastomotic leakage. Multiple logistic regression analysis showed a significant influence of hypertension, smoking and ASA grade on complications. CONCLUSIONS: About 40% of patients who undergo Hartmann's procedure will not have a reversal. Reversal is a feasible operation for selected patients, but there is a high complication rate.     

Mothers’ Reports of Postpartum Pain Associated with Vaginal and Cesarean Deliveries: Results of a National Survey

ABSTRACT: Background: As cesarean rates increase worldwide, a debate has arisen over the relationship of method of delivery to maternal postpartum physical health. This study examines mothers’ reports of their postpartum experiences with pain stratified by method of delivery. Methods: Listening to Mothers II was a survey of a total of 1,573 (200 telephone and 1,373 online) mothers aged 18 to 45 years, who had a singleton, hospital birth in 2005. They were interviewed by the survey research firm, Harris Interactive, in early 2006. Online respondents were drawn from an existing Harris panel. Telephone respondents were identified through a national telephone listing of new mothers. Results were weighted to reflect a United States national birthing population. Mothers were asked if they experienced any of eight postpartum conditions and the extent and the duration of the problem. Responses were compared by method of delivery. Results: The most frequently cited postpartum difficulty was among mothers with a cesarean section, 79 percent of whom reported experiencing pain at the incision in the first 2 months after birth, with 33 percent describing it as a major problem and 18 percent reporting persistence of the pain into the sixth month postpartum. Mothers with planned cesareans without labor were as likely as those with cesareans with labor to report problems with postpartum pain. Almost half (48%) of mothers with vaginal births (68% among those with instrumental delivery, 63% with episiotomy, 43% spontaneous vaginal birth with no episiotomy) reported experiencing a painful perineum, with 2 percent reporting the pain persisting for at least 6 months. Conclusions: Substantial proportions of mothers reported problems with postpartum pain. Women experiencing a cesarean section or an assisted vaginal delivery were most likely to report that the pain persisted for an extended period. (BIRTH 35:1 March 2008)     

Nutritional status and wound severity of overweight and obese patients with venous leg ulcers: A pilot study

Obesity is a chronic disease that is linked to the presence of numerous chronic illnesses, including venous disease. Venous disease can lead to chronic wounds, which may be exacerbated by vitamin, mineral, and macro-nutritional deficiencies. A cross-sectional observational design was used to examine the nutritional status of patients with chronic venous leg ulcers (VLUs) who are overweight or obese and to explore the relationship between nutritional status and severity of venous ulceration. Nutritional status was evaluated using anthropometric measurements, nutrient analysis from a 3-day dietary intake log, serum albumin, vitamins A and C, and zinc levels. Wound severity was assessed using the Leg Ulcer Measurement Tool (LUMT). Eight patients participated; six patients were men, and all eight patients were more than 50 years of age. Patients had an average daily caloric intake below their estimated caloric need. When compared with recommended daily intake levels, dietary nutrient intake was suboptimal for protein, vitamin C, and zinc. Serum levels were below normal for at least one of these nutrients in six patients. A positive correlation was found only between serum albumin, average daily intake, and percent recommended daily intake of protein (r(s) = 0.93, P = .003). An inverse relationship was found between LUMT score and serum vitamin A levels (r(s) = -0.83, P = .01), and a positive correlation was observed between LUMT score and serum vitamin C (r(s) = 0.74, P = .04). No clear relationships were shown among serum zinc, albumin, and LUMT scores. Overweight and obese patients with VLU show nutritional deficits that are similar to those of the broader population of patients with leg ulcers. The relationships found between vitamins A and C and leg ulcer severity warrant further exploration. The nutritional differences in the study need to be examined in a larger sample of overweight and normal-weight patients to determine whether overweight patients are at greater risk for prolonged VLU because of poor nutrition than non-overweight patients.
