Effect of imagery on children's pain and anxiety during cardiac catheterization.

Children who undergo cardiac catheterization present pain management challenges to nurses. In this experimental study, the investigator examined the effect of imagery on children's pain and anxiety during cardiac catheterization. Twenty-four children, aged 9 to 17 years were randomly assigned to a control, presence, or imagery condition. Physiological, psychological, and behavioral data were used to rate children's pain and anxiety during cardiac catheterization. Children in the imagery condition displayed fewer distress behaviors during cardiac catheterization. Children in the presence condition reported the lowest levels of pain. Cortisol elevation over baseline was lowest in the control group, a result consistent with findings in previous studies. Several correlations of interest are reported. Implications for nursing practice and research are discussed.

Neurologic complications due to catheterization.

In our university cardiac center, the incidence of a cohort of children with acute neurologic complications resulting from cardiac catheterization performed for acyanotic or cyanotic congenital heart disease is 0.38% (14 children of a total of 3,648 catheterization procedures). Neurologic complications consisted of convulsion (n = 10), stroke (n = 6), intracranial hemorrhage (n = 2), extrapyramidal features (n = 1), paraplegia (n = 1), visual impairment (n = 1), hearing impairment (n = 1), and brachial plexus injury (n = 1). The main risk factors included prolonged duration of catheterization procedure and interventional manipulation in addition to cardiac catheterization. The possible mechanisms causing brain injury included cerebral embolism from local clots and hypoxia resulting from complications during the procedure. Other complications included intracranial hemorrhage secondary to anticoagulation and peripheral plexopathy because of prolonged fixed posture during anesthesia. The prognosis for the majority of patients with stroke is good. Neurologic sequelae, such as global developmental delay or epilepsy, occurred in those with hypoxic-ischemic encephalopathy.

Is cardiac catheterization a prerequisite in all patients undergoing bidirectional cavopulmonary anastomosis?

Traditionally, all patients undergo cardiac catheterization before bidirectional cavopulmonary anastomosis (BCPA). The purpose of this study was to determine if preoperative catheterization is necessary when echocardiographic parameters appear favorable. A retrospective review was performed of all patients who underwent BCPA (n = 142) between February 1996 and May 2001. Echocardiographic criteria defining a favorable BCPA candidate included good ventricular function, moderate or less atrioventricular and semilunar valve regurgitation, absence of ventricular outflow tract obstruction, normal proximal branch pulmonary artery (PA) size, and low PA pressures estimated by PA band gradient or systemic PA shunt velocity. The median age at operation was 7 months (range: 2-11) and weight was 6.2 kg (range: 2.7-7.1). There were 73 unfavorable candidates. Patients with hypoplastic left heart syndrome (n = 23) and pulmonary atresia with intact septum (n = 15) predominated among the unfavorable group. All patients were catheterized. This provided additional information on PA pressures in 3 patients in the favorable group but did not defer operation or influence outcome (no mortality, prolonged pleural drainage, or longer intensive care department stay). All 3 patients are alive at a mean follow-up of 51 months. The 30-day mortality was 2% (4 of 151 patients), all in the unfavorable group. Overall, 20 patients (13%) required arterioplasty of PAs at the time of BCPA. BCPA can be performed with a low risk of morbidity and mortality in a wide range of patients. By using commonly acquired echocardiographic parameters, a low-risk subgroup of patients can be identified who can safely avoid preoperative cardiac catheterization.

Which patients with unstable angina or non-Q-wave myocardial infarction should have immediate cardiac catheterization? A clinical decision rule for predicting who will fail medical therapy.

Unstable angina and non-Q-wave myocardial infarction (MI) are common and costly clinical events, but there is considerable uncertainty about optimal clinical management of these syndromes. We developed a prediction rule to help clinicians determine which patients with unstable angina or non-Q-wave MI are likely to "fail" medical therapy and ultimately require cardiac catheterization within 6 weeks of presentation. Subjects were 733 patients presenting with unstable angina or non-Q-wave MI enrolled in the TIMI IIIB trial and randomized to initial medical management. We developed a prediction rule based on logistic regression analysis of baseline data from history, physical examination, electrocardiogram, and blood studies. The outcome of interest was "failure" of medical therapy, defined as need for coronary catheterization within 42 days. Significant predictors of "failing" medical therapy included ST segment depression >or= .1 mV (odds ratio, OR, = 2.7, 95% confidence interval, CI, 1.8-4.1), accelerated angina in the prior 2 months (OR = 1.8, 95% CI 1.2-2.6), nitrate use in the prior week (OR = 1.6, 95% CI 1.1-2.2), exertional angina in the prior 2 months (OR = 1.6, 95% CI 1.1-2.2), and cardiac troponin I (cTnI) >or= 0.4 ng/mL (OR = 1.4, 95% CI 1.1-1.9). We used these variables to build a risk score by assigning point values based on these ORs. The risk score had a moderate ability to predict which patients would subsequently fail medical therapy and undergo cardiac catheterization (c = 0.682). Out of a total risk score of 13, failure of medical therapy occurred in 86% of patients who had a risk score >or= 8 (n = 111), 78% of patients who had a risk score >or= 6 (n = 240), and 72% of patients who had a risk score >or= 4 (n = 438). At scores of < 2 (n = 88), 40% of patients failed medical therapy. Although the management of unstable angina is in constant evolution, clinicians will always be faced with determining which patients should be managed most invasively. The simple prediction rule we present can be applied to patients with unstable angina or non-Q-wave MI at the time of presentation to predict which patients have a high probability of failing medical therapy. Such a rule may be useful for identifying patients who should be considered for early cardiac catheterization.

A comparison of structured versus guided preheart catheterization information on mood states and coping resources.

A rapid growth in outpatient surgical procedures has been necessary to help alleviate expensive health care costs. Because procedures, such as heart catheterization, require a short patient stay, preparatory information is often structured and delivered concisely. The purpose of this study was to determine if heart catheterization patients who receive guided precatheterization information had reduced stress compared with heart catheterization patients who received structured precatheterization information. Using a two-group pretest/posttest design, 89 subjects were randomly assigned to two different preparatory nursing interventions. Data were collected on outpatients' coping resources and mood states, which served as measures of stress. No significant differences in stress were found between the guided and structured preparatory information groups. The results indicated that a variety of approaches can be used to prepare patients for outpatient heart catheterization procedures.

Diagnosis and treatment of postoperative chyle leakage via percutaneous transabdominal catheterization of the cisterna chyli: a preliminary study.

PURPOSE: To assess the feasibility of percutaneous transabdominal puncture and catheterization of the cisterna chyli or lymphatic ducts (PTCLD) in patients with postoperative chyloperitoneum and chylothorax, and to identify and possibly embolize the chylous fistula. MATERIALS AND METHODS: Five patients had postoperative uncontrolled chyle fistulas. Two patients with chylothorax had thoracic duct (TD) ligation after esophagectomy and neck surgery. The other three patients had chylous ascites after surgery of the pancreas, the aorta, and the esophagus, respectively. After lymphographic opacification, the cisterna chyli (CC) or retroperitoneal lymph ducts were punctured transabdominally with a 21-gauge needle and catheterized with a 3-F catheter to reach the TD if possible. Microcoils were used to embolize a TD laceration. RESULTS: Lymph ducts as small as 2-3 mm were catheterized successfully in three patients. The TD was catheterized in two patients; one TD fistula was embolized with cure of chylothorax. In one patient with a surgically tied TD, duct occlusion was confirmed despite continued pleural effusion. Three fistulas, not seen with lymphography, were identified in two of three chylous ascites and one chylothorax. There was no morbidity. As a result of this procedure, four of five patients did not require repeated operation. CONCLUSIONS: PTCLD in the study of chyle fistulas was feasible and safe in the management of five patients and clinically useful in four patients; transabdominal catheter lymphography with aqueous contrast medium is more sensitive than pedal lymphography. Further evaluation is necessary.

Psychologic preparation to decrease anxiety associated with cardiac catheterization.

Undergoing a cardiac catheterization arouses anxiety of most patients. Coronary angiography plays an essential role in the diagnostic evaluation of the patient with suspected or known cardiac disease, and it is an important preoperative cardiac screening protocol for vascular surgery patients. Studies on psychologic preparation have concluded that preparatory techniques--specifically, sensory-perceptual informational and modeling--are beneficial in reducing patients' anxiety in various situations, including cardiac catheterization. The purpose of this study was to compare the preparatory informative (sensory and procedural data) and modeling strategies in reducing anxiety before cardiac catheterization. The research hypothesis that persons (n = 30) given a combination of sensory-perceptual informational preparation and modeling preparation would exhibit less anxiety than persons receiving one preparation alone was not supported. Although no significant difference existed between the postintervention anxiety scores for the 3 different treatment groups, a significant difference existed between the preintervention and postintervention anxiety scores overall. Therefore, this study validates the psychologic and nursing literature that states psychologic preparation is beneficial in reducing patients' anxiety before a stressful experience such as cardiac catheterization. The study findings also revealed an interesting trend for employing a modeling technique. This information contributes to nursing knowledge and may alter and make more effective the nature of standard psychologic preparation for patients undergoing any invasive procedure.

[Cardiac catheterism. Nursing performance in the critical unit].

In acute myocardial infarction (AMI), ischemia is acute, intense and maintained, it being one of the main causes of death in our society. Immediate treatment may reduce it considerably. The objectives established in this study were the following: Verify the course of the AMI treatments Verify the evolution in hemostatic methods in patients subjected to cardiac catheterism. Elaborate new nursing protocols for pre- and post-catheterism care. A retrospective, descriptive study was done. From October 1999 to December 2002, a total of 1969 patients were admitted to our unit. Of these, 818 were admitted due to heart disease. Those whose diagnosis was AMI or Angina were selected among the latter and then those in whom cardiac catheterism was done were chosen. It was conducted in a 12 bed polyvalent ICU, the data collection being done by five nurses from that unit based on clinical and nursing history. An increase in the performance of diagnostic and therapeutic cardiac catheterism in recent years was observed, and there was also an increase in intraarterial suture as hemostasis method in detriment to mechanical compression. New standardized nursing products were elaborated to facilitate and improve the care of these patients and try to reduce preparation time for their transfer to the hemodynamics unit, given the urgency existing in most of the cases.

Supraclavicular versus infraclavicular subclavian vein catheterization in infants.

BACKGROUND: Central venous catheterization is an important procedure for infant patients for a number of different purposes, including nutritional support, surgical operation, hemodynamic monitoring, and multiple lines for critical care medications. Subclavian vein catheterization (SVC) is one of the central vein catheterization techniques. SVC can be performed from 4 different locations: right supraclavicular (RSC), left supraclavicular (LSC), right infraclavicular (RIC), and left infraclavicular (LIC). The purpose of this study was to evaluate the relative effectiveness and complication risks of these 4 SVC locations in infants. METHODS: In our pediatric intensive care unit, which is part of a tertiary medical center, a well-trained fellow doctor performed the following catheterizations: 21 RSC, 24 LSC, 24 RIC, and 22 LIC, for a total of 91 SVC operations in infants. The patients were placed in the Trendelenburg position. The site of puncture was decided by the operator. Statistical significance was analyzed according to Fisher's exact test and 2-sample t test. RESULTS: The overall success rate was 90.1% (82 out of 91 operations). No statistically significant differences were noted among these 4 groups, either in the success or complication rate. There were 6 cases of arterial puncture (5 supraclavicular and 1 infraclavicular, p = 0.09), 2 cases of pneumothorax (1 RSC and 1 RIC), and 2 cases of malpositioned catheter (1 RSC and 1 RIC). There was no mortality. CONCLUSION: In our study, we found that there was no statistically significant difference among the 4 SVC locations in effectiveness of operation or in risk of complication. There was a tendency to damage the subclavian arteries through the supraclavicular route.

Elevations of troponin I after interventional cardiac catheterization.

BACKGROUND: Elevation of cardiac troponin I in the serum is a specific marker for myocardial injury. We measured levels of troponin I in the serum in children before and after cardiac catheterization to determine if this procedure was associated with an increase in levels of troponin. METHODS: We enrolled patients under 21 years of age undergoing cardiac catheterization at our institution. A baseline sample of serum was drawn at the start of the procedure. Repeat samples were obtained immediately after, and six hours subsequent to the procedure. All samples were analyzed for cardiac troponin I using the Abbott AxSYM microparticle immunoassay system. Levels were considered normal (0-0.4 ng/ml) or elevated (>0.4 ng/ml). Patients were excluded if the baseline level was elevated. RESULTS: Levels of cardiac troponin I were elevated in the serum from 11 of 14 (79%) cases immediately after the procedure (p < 0.0001), and in 12 of 14 (86%) six hours later (p < 0.0001). Only 2 patients had recognized complications potentially causing myocardial injury. CONCLUSION: Levels of cardiac troponin I increase in the serum in a high proportion of children after cardiac catheterization. These elevations can be observed immediately, and are maintained for at least six hours. Our study suggests that cardiac catheterization, predominantly intervention, is associated with myocardial injury, even in the absence of complications.

Personality and coping with a common stressor: cardiac catheterization.

The association between coping and personality was examined in a sample of 204 cardiac catheterization patients who were asked to evaluate the use of specific coping strategies used to deal with their cardiac catheterization. Personality, as measured by the NEO Five-Factor Inventory (FFI), was moderately correlated with coping measures. In multivariate analyses, after considering confounding factors, Neuroticism was positively and Extraversion was negatively related to avoidance coping and Neuroticism was negatively associated with counting one's blessings as a coping strategy. Personality was not related to either problem solving or seeking social support coping strategies for individuals experiencing a cardiac catheterization. However, important covariates were associated with coping strategies. Not being married was negatively correlated with use of seeking social support and not having a confidant was negatively related with seeking social support and positively with avoidance. These results suggest that there are specific relationships between personality and coping, but these relationships are, for the most part, moderate in persons coping with a cardiac catheterization, and that coping processes are associated with individual differences in available social resources.

Mortality related to diagnostic cardiac catheterization. The importance of left main coronary disease and catheter induced trauma.

BACKGROUND: The mortality of diagnostic catheterization is very low but still exists. Large series have documented left main disease as the most important anatomical risk factor but have not clarified the mechanism. OBJECTIVES: To determine the mortality of diagnostic catheterization in a single high volume centre over a 9 year period and assess any change during this period; to compare this experience with that of larger multicentre surveys; to identify the clinical and anatomical risk factors; to investigate the mechanism of the event; to develop guidelines for prevention METHODS: Cardiac catheterization records were reviewed over a 9 year period and patients dying during or within 24 hours were identified. The clinical and anatomical profile of the patients who died were compared with the overall group to search for independent risk factors. The angiograms of the deaths were reviewed for a mechanism. RESULTS: There were 30 deaths in 42,345 procedures (0.071%). There was no change in the incidence over the 9 years. Left main coronary disease was an overwhelming risk factor (incidence 0.7%, p < .002 compared to all other subgroups) and no other anatomical subgroup including triple vessel disease was at greater risk than the overall group. Dissection of the left main coronary artery by the diagnostic catheter was the mechanism of death in 20 cases (67%) CONCLUSIONS: Left main disease and catheter induced trauma are the most important risk factor for and mechanism of death during diagnostic catheterization and may account for the unchanging incidence. Technical guidelines are described which may reduce this risk.

Clean intermittent catheterization and prevention of renal disease in spinal cord injury patients.

Upper urinary tract complications have been reported in about 20-30% of spinal cord injury patients. Their pathogenesis is linked to the presence of high-pressure uninhibited detrusor contractions, high leak point pressure and low bladder compliance. The aim of this study was to evaluate the incidence of upper urinary tract complications in two homogeneous groups of spinal cord injury patients with different bladder emptying modalities (intermittent catheterization vs. tapping, abdominal straining, Crede's manoeuvre) and the relationship with clinic and urodynamic features. A total of 17 patients (22%) had upper urinary tract complications. The incidence of both urinary tract dilatation and vesicoureteral reflux was significantly lower in patients having intermittent catheterization (P = 0.03 and 0.04 respectively). Intermittent catheterization thus seems to be effective in preventing upper urinary tract disease in spinal cord injury patients requiring mechanical bladder emptying modalities. The finding of upper urinary tract complications also in patients having intermittent catheterization showing high intravesical pressures stresses the need of adding anticholinergic medications to the rehabilitation regimen of these patients.

Urethral epithelial cells on the surface on hydrophilic catheters after intermittent catheterization: cross-over study with two catheters.

AIM: To count the number of cells on the surface of the two commercial hydrophilic catheters, Lofric and EasiCath used for intermittent catheterization (IC) after 30-60 s in water without the necessity of catheter jelly. PARTICIPANTS: Twenty spinal cord lesioned (SCL) individuals. Six were women, and 14 men. METHODS: IC was performed on average five times a day (range: 4-10). In a randomised cross-over design all catheterizations were performed either with Lofric or EasiCath in two consecutive 24 h periods. The catheter used for the last catheterization in each 24 h period was fixed, and divided into pieces of 5 cm. From each of these a piece with the length of 5 mm was taken for surface microscopy after staining. The total number of cells was counted without knowledge of the type of catheter. According to the fractionator principle an unbiased estimate of the total number of cells on the surface of the cateter was calculated. RESULTS: There was no difference in the number of urethral epithelia cells on the catheters. No granulocytes were identified. The number of cells identified on the catheters were from 30 to > 10 000. No differences related to age, level of SCL, ASIA impairment scale, months since SCL or type of IC were found. There was a trend that women had higher cell counts than men. CONCLUSION: No difference was found regarding number of urethral epithelial cells on the surface of the catheters after catheterization. This indicates no difference in urethral trauma between the two catheters.

The importance of osmolality for intermittent catheterization of the urethra.

OBJECTIVES: The urethral trauma after catheterization with intermittent catheters was studied histologically using unconscious rabbits. SETTING: The study was performed at Astra Hässle, Mölndal, Sweden. MATERIALS AND METHODS: Fifteen rabbits were randomized into five groups (three rabbits in each group), one control group and four groups catheterized with four different LoFric catheters (Astra Tech, Mölndal, Sweden): (1) control (not catheterized); (2) salt coated (i.e. high osmolality catheters) with drainage eyes; (3) without salt (i.e. low osmolality catheters) and with eyes; (4) with salt coating but without drainage eyes; and (5) without neither salt coating nor drainage eyes. The urethral injuries were evaluated using a four graded histological scale. RESULTS: The results showed that salt coated LoFric catheters gave less urethral trauma than LoFric catheters without salt. This was also supported by the significantly lower removal friction measured during withdrawal of the high osmolality catheters. No significant differences either in removal friction or in urethral trauma could be observed between LoFric catheters with or without drainage eyes. CONCLUSION: It may be concluded that osmolality is one important factor (there might be others, like e.g. water binding ability) when comparing different hydrophilic catheters, in regards to removal friction and urethral trauma. Furthermore it is suggested that there is no difference in urethral trauma between catheters with eyes or without eyes. To minimize the risk of urethral trauma, high osmolality catheters are recommended, especially when the catheterization times are a few minutes or more.

Clinical and economic consequences of volume- or time-dependent intermittent catheterization in patients with spinal cord lesions and neuropathic bladder.

STUDY DESIGN: Open comparative study. OBJECTIVE: To compare the impact of volume-dependent intermittent catheterization (VDIC) and time-dependent intermittent catheterization (TDIC) on financial burden and clinical outcomes in patients with spinal cord lesions (SCL). SETTING: Department of Spinal Rehabilitation, Loewenstein Rehabilitation Hospital, Israel. METHOD: Economic and clinical outcomes were examined in 13 SCL patients treated with VDIC following bladder volume measurement by a portable ultrasound device (the study group), and in 11 patients treated with TDIC (the control group). Patients were followed for 12-30 days. Costs were calculated according to December 2003 prices at Loewenstein Hospital. The t-test and the Fisher's Exact Test were employed for comparisons between the groups. RESULTS: The number of catheterizations per patient per day, the time required to perform volume measurements and catheterizations, and their total cost, were approximately 44, 49, and 46% lower in the study group than in the control group. SCIMU (representing bladder management functioning) increased during the study in both groups, and the increase was 31% higher in the study group than in the control group. Urinary infection was found in three patients in the control group and in none in the study group. CONCLUSION: VDIC has economic and probably also clinical advantages over TDIC.

An exploration of the relationships between uncertainty, psychological distress and type of coping strategy among Chinese men after cardiac catheterization.

The experience of cardiac catheterization (CC) has included feelings of uncertainty, stress, fear and anxiety in many patients. However, conflicting findings from previous research have been reported. Chinese patients who undergo CC may experience psychological distress in a different way to other cultures as a result of traditional beliefs. Moreover, little research examining the impact of CC among Hong Kong Chinese has been carried out. Therefore, the aim of the study was to explore relationships between uncertainty, psychological distress and coping strategy in Chinese men after CC, using Mishel's model of uncertainty in illness as a framework. A convenience sample of 27 men hospitalized for cardiac catheterization participated in this study using a descriptive, correlational research design. Ethical approval was obtained from the Ethics Committee of the Medical Faculty at the Chinese University of Hong Kong and from the Executive Committee of the hospital. Participation was on a voluntary basis with patient confidentiality assured. Self-report questionnaires included Chinese versions of Mishel's Uncertainty in Illness Scale (MUIS), the Profile of Mood States (POMS), the State-Trait Anxiety Inventory (STAI) and the Chinese Coping Scale (CCS) for data collection. Data were analysed using the Statistical Package for Social Sciences. High mean scores for uncertainty (mean=101.4, SD=11.49) and variables measuring psychological distress (mood disturbance mean=36.6, SD=33.6, state-anxiety mean=39.1, SD=8.95, trait-anxiety mean=43.7, SD=8.1) among these participants suggest that Hong Kong Chinese men experience uncertainty and psychological distress when undergoing cardiac catheterization. Strong relationships between uncertainty and mood disturbance (r=0.57, P=0.01), trait-anxiety and mood disturbance (r=0.65, P=0.01) and state-anxiety and external coping strategies (r=0.50, P=0.05) were found. These findings suggest that relationships between uncertainty, psychological distress and external coping strategies exist in Chinese men hospitalized for cardiac catheterization. Moreover, these findings may help nurses' design culturally specific interventions for their patients.

Is urethral catheterization a successful alternative to suprapubic aspiration in neonates?

OBJECTIVE: To compare urine collection by urethral catheterization with suprapubic aspiration in a neonatal intensive care unit. METHODOLOGY: All urine collections were documented, the collection methods attempted recorded and success rates calculated. The incidence of contaminated specimens was determined. The infants ranged in weight from 570 g to 4180 g and in gestation from 24 to 44 weeks. RESULTS: Thirty-two out of 65 (49%) suprapubic aspirations were successful. Overall 33/42 (77%) of catheterizations were successful, 12/18 (67%) were successful when following an unsuccessful SPA. No SPA was contaminated compared to 7/22 (22%) of the catheter specimens. Urinary tract infection was present in 4/63 (6.3%) infants. There were no complications following catheterization. CONCLUSIONS: Urethral catheterization is a useful and safe alternative to suprapubic aspiration, but suprapubic aspiration remains the method of first choice.
