- AIM: This paper is a report of a study to explore the use of imagery to describe the experience of confronting brain death in a close relative. BACKGROUND: The brain death of a loved one has been described as an extremely difficult experience for close relatives, evoking feelings of anger, emotional pain, disbelief, guilt and suffering. It can also be difficult for relatives to distinguish brain death from the state of coma and thus difficult to apprehend information about the diagnosis. METHODS: Narrative theory and a hermeneutic phenomenological method guided the interpretation of 17 narratives from close relatives of brain dead patients. All narratives were scrutinized for experiences of brain death. Data were primarily collected in 1999. The primary analysis related to close relatives' experience of brain death in a loved one. A secondary analysis of the imagery they used to describe their experience was carried out in 2003. FINDINGS: Six categories of imagery used to describe the experience of confronting a diagnosis of brain death in a loved one emerged: chaotic unreality; inner collapse; sense of forlornness; clinging to the hope of survival; reconciliation with the reality of death; receiving care which gives comfort. Participants also identified two pairs of dimensions to describe their feelings about the relationship between their brain dead relative's body and personhood: presence-absence and divisibility-indivisibility. Being confronted with brain death meant entering into the anteroom of death, facing a loved one who is 'living-dead', and experiencing a chaotic drama of suffering. CONCLUSION: It is very important for members of the intensive care unit team to recognize, face and respond to these relatives' chaotic experiences, which cause them to need affirmation, comfort and caring. Relatives' use of imagery could be the starting point for a caring conversation about their experiences, either in conversations at the time of the death or when relatives are contacted in a later follow-up.

Risk of central pontine myelinolysis in the treatment of severe hyponatremia
- 1989
-
In: Läkartidningen. - 0023-7205. ; 86:20, s. 1905-7
-
Journal article (peer-reviewed)abstract
- Central pontine myelinolysis is a life-threatening condition involving the demyelination of axons in certain areas of the brain. It has been shown almost invariably to occur in connection with hospital care. In recent years, a connection has been noted between the rapid restitution of low serum sodium and the development of the condition. In this review, the most recent scientific information is summarized. It is concluded that the risk should always be considered in treating a hyponatremic patient. The serum sodium level should be raised slowly and the acute treatment ended before normal serum sodium levels are reached, ie when the patient is still slightly hyponatremic.

Preoperative risk assessment in vascular surgery patients
- 1999
-
In: Current Anaesthesia and Critical Care. ; 10, s. 179-185
-
Research review (peer-reviewed)abstract
- The patient scheduledf or peripheral vascular surgery is an increaseda naestheticc hallenge, mainly because of coexisting generalized cardiovascular atherosclerotic involvement leading to a high risk of perioperative cardiac complications. In clinical practice it is of importance preoperatively to predict, as accurately as possible, the potential risk of complications so that proper risk-reducing measures can be taken. Relevant clinical data, which have been included by Goldman and Detsky in multifactorial cardiac risk indices, are of potential value for differentiating between patients at low, intermediate, or high risk of perioperative cardiac morbidity and mortality. Patients with low risk scores can be accepted for surgery without further testing, thereby allowing more extensive cardiac testing, such as ambulatory ECG monitoring, exercise stresst esting, echocardiography,d ipyridamole thallium imaging, or coronary angiography,t o be reserved for patients with higher risk scores or overt cardiac problems. The risk stratification is of importance not only for decisions on preoperative prophylactic therapeutic measures (e.g. optimization of medical therapies, coronary artery revascularization), but also for decisions on intraoperative anaesthetic management and postoperative care

Clinical competence in pain assessment.
- 2000
-
In: Intensive & Critical care Nursing. - 0964-3397. ; 16:5, s. 273-82
-
Journal article (peer-reviewed)abstract
- Our knowledge about the content of the clinical knowledge used by nurses in a surgical recovery unit for assessment of postoperative pain is fairly limited. The aim of the present study was to analyse and describe the variations of nurses' conceptions of the impact of clinical experience on competence in post-operative pain assessment. The informants consist of critical care nurses. A phenomenographical approach has been applied to tape-recorded interview data. The results reveal that clinical competence in pain assessment was described in three categories: (a) to be able to see; (b) to be able to differentiate; (c) to be able to give. The observations articulate what nurses perceive that they have learnt from experience in performing many clinical pain assessments and point to some difficulties in using a single-data source for the development of valid and truthful professional knowledge. In the development of professional experience, it is of the utmost importance to be able to change perspective from what is most frequent and general to what is special and unique, to base one's standpoint on the individual patient's experience and integrate this with previous professional experience.

Haemodynamic effects of volume resuscitation by hypertonic saline-dextran (HSD) in porcine acute cardiac tamponade.
- 2004
-
In: Acta anaesthesiologica Scandinavica. - 0001-5172. ; 48:1, s. 46-54
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Hypertonic saline-dextran (HSD) has been utilized for small-volume resuscitation in acute circulatory shock. However, HSD has also been reported to induce myocardial depression. The aim of this study was to examine the effects of HSD on cardiac performance and splanchnic perfusion in a low cardiac output model based on experimental cardiac tamponade. METHODS: Seven anaesthetized, mechanically ventilated pigs of both sexes (weight 24 +/- 2 kg, mean +/- SEM) completed a randomized, cross-over protocol. A low cardiac output state was established by intrapericardial infusion of dextran. Animals were resuscitated by bolus infusions (4 ml kg(-1) in 2 min) of either 7.5% hypertonic saline-dextran or Ringer's acetated solution (RAc) and then observed during tamponade (20 min) and following its release (40 min). Central haemodynamics, portal venous (QPV) and renal arterial (QRA) flows were measured together with gastric, jejunal, hepatic and renal laser-Doppler flowmetry. RESULTS: Resuscitation using HSD in a low cardiac output state completely restored QPV and improved gastric, jejunal, hepatic and renal microcirculation as assessed by laser-Doppler flowmetry while no significant effect was observed in QRA. No such beneficial effects could be observed when animals were resuscitated using RAc. The improved haemodynamic state by HSD was maintained following release of cardiac tamponade while perfusion in RAc resuscitated animals returned to baseline or even remained depressed (hepatic and renal microcirculation). No signs of cardiodepression by HSD were observed. CONCLUSION: Resuscitation using HSD in a low cardiac output state restored splanchnic perfusion and microcirculation without any signs of cardiodepression.

Acute pain services
- 2003

Journal article (peer-reviewed)abstract
- An interdisciplinary acute pain service (APS) team seems the most attractive clinical organization model for postoperative pain management (POPM) to fulfil the intentions of pain management guidelines in practice. The specific knowledge of anaesthesiologists in the use of drugs and techniques for pain alleviation is of specific importance. Therefore, the anaesthetist is usually the team leader and works together with nurses in the postanaesthesia care unit (PACU), acute pain nurses (APN) and surgical ward nurses. A nurse-based anaesthesiologist supervised type of APS seems in several respects to be a suitable model for POPM in clinical practice.

Routine intra-operative assessment of pain and/or depth of anaesthesia by nurse anaesthetists in clinical practice.
- 2001

In: Journal of clinical nursing. - : Wiley Interscience. - 0962-1067 .- 1365-2702. ; 10:4, s. 429-36

Journal article (peer-reviewed)abstract
- Patient safety and comfort during general anaesthesia and surgery are to a considerable extent dependent on the capability of anaesthesia personnel to interpret directly monitored as well as indirect clinical signs of pain and/or depth of anaesthesia. The aim of the present study was to evaluate how nurse anaesthetists in their clinical routine work assess and interpret intra-operative responses evoked by pain stimuli and/or insufficient depth of anaesthesia. A questionnaire was designed to assess the perceived relevance and validity of cardiovascular, respiratory, mucocutaneous, eye-associated, and muscular responses for routine assessment of intra-operative pain and/or insufficient depth of anaesthesia in patients undergoing surgery under general anaesthesia. Data were obtained from 223 nurse anaesthetists working at nine different university anaesthesia departments in Sweden. A number of significant indicators for pain and depth of anaesthesia could be identified for spontaneously breathing as well as for mechanically ventilated patients. No variable was considered entirely specific for either intra-operative pain or depth of anaesthesia. Changes in breathing rate/volume, central haemodynamics (BP, HR), lacrimation, and presence of moist and sticky skin were given higher score values as indicators of pain than as indicators of depth of anaesthesia. Occurrence of grimaces, attempted movements, and presence of non-centred pupils were variables considered more indicative of insufficient depth of anaesthesia than intra-operative pain. In conclusion, it is obvious from the present data that indirect physiological signs of intra-operative pain and depth of anaesthesia are still considered of importance by Swedish anaesthesia nurses in the anaesthetic management of surgical patients.
