Comparison of open-chest cardiac massage techniques in dogs.

Manual compression of the heart during open-chest cardiac massage (OCPR) has been shown to be superior to closed-chest compression. Our study sought to determine, in a canine model, the optimal hand position for manual compression of the heart. Twelve dogs were anesthetized with ketamine, an orotracheal tube was placed, and anesthesia was maintained with halothane and nitrous oxide. Cannulae were placed to monitor diastolic (DBP) and systolic (SBP) blood pressures, intracranial pressure (ICP), and common carotid blood flow (CCBF). Control values were obtained under light general anesthesia, and ventricular fibrillation was induced. External CPR (ECPR) was performed with a mechanical compressor before opening the chest and pericardium through the left fifth interspace. The following sequence of three hand positions was used for OCPR: technique A, one-handed technique with thumb on left ventricle, fingers over the right ventricle, and apex in palm; technique B, two-handed technique with right ventricle cupped in left hand and fingers of right hand over left ventricle; and technique C, one-handed technique with fingers of right hand over left ventricle and heart against sternum. Each was done at a rate of 60 compressions per minute with the operator blind to results during performance. All three techniques produced significantly (P less than .05) greater DBPs and CCBFs when compared with ECPR. All three also produced significantly lower (P less than .05) ICPs when compared with ECPR. DBPs, SBPs, CCBFs, and cerebral perfusion pressures were similar for techniques B and C, and all were significantly greater (P less than .05) than those achieved with technique A.(ABSTRACT TRUNCATED AT 250 WORDS)

Termination of paroxysmal supraventricular tachycardia by digital rectal massage.

A 71-year-old woman with an episode of paroxysmal supraventricular tachycardia (PSVT) complicated by angina pectoris and hypotension had her arrhythmia abruptly terminated by digital rectal massage (DRM) after other vagotonic maneuvers had failed. DRM termination of PSVT has not been heretofore reported. In treating PSVT by physical vagotonic maneuvers, DRM may be preferable to other techniques because of the decreased likelihood of complications noted with other such maneuvers.

Femoral venous pulsations during open-chest cardiac massage.

We describe the cases of two children with easily palpated femoral pulses during open-chest cardiac massage after aortic occlusion. These pulsations must have arisen from the femoral veins, implying that during CPR in children the usual anatomic landmarks for femoral venous access may be unreliable, and femoral pulsations do not necessarily reflect arterial flow. Femoral pulses may signify to-and-fro inferior vena caval flow that compromises venous return, adversely affecting cardiac output and the effectiveness of medication administration to the lower extremity.

Prehospital use of minimally invasive direct cardiac massage (MID-CM): a pilot study.

BACKGROUND: Internal cardiac compressions are more efficient than closed chest compressions (CCC) in cardiac arrest (CA). AIM OF THE STUDY: To evaluate the prehospital feasibility of performing a new method of minimally invasive direct cardiac massage (MID-CM TheraCardia Inc.). METHODS: Prospective non-randomized open study, after ethical committee approval. Inclusion of 18-85 years old patients in witnessed CA if BLS>5 min and unsuccessful ACLS>20 min after CA. The MID-CM is an atraumatic manual cardiac pumping system deployed in the thoracic cavity through a small incision. Evaluation of: ease of insertion and performing MID-CM, complications, end-tidal CO(2) (PETCO(2)), non invasive arterial blood pressure (NIBP) and return of spontaneous circulation (ROSC). Values are mean+/-SD (min-max). RESULTS: Twenty-five patients included. Mean age 59+/-16 years (26-85); BLS started at 8+/-5 min (0-20), compressions started at 47+/-10 min (29-74) after CA. Dissection and insertion was fast and easy (<1 min). Deployment of the MID-CM was difficult in two patients because of pericardium adhesions and cardiomegaly. In six patients compressions were more difficult because of a 'stone heart' phenomenon. Compressions were possible during ambulance transport of four patients. There was a good palpable carotid pulse in all patients receiving internal compressions. There was a trend in increase of PETCO(2) compared to CCC. NIBP could be measured during MID-CM compressions in 9 patients (systolic>85 mmHg), never during CCC. Seven patients had a ROSC, but only four patients were admitted alive. There was no long term survival. One patient had a serious complication (heart rupture). DISCUSSION: Prehospital use of MID-CM is possible, but it is not comparable to any other resuscitation technique. Training of medical teams is mandatory to obtain good skills and to avoid complications. Further studies are necessary to evaluate efficiency and survival compared to closed chest compressions.

Life-threatening cervico-mediastinal haematoma after carotid sinus massage.

Retropharyngeal and cervico-mediastinal haematomas are rare but potentially fatal entities. The potential for airway compression necessitates rapid assessment and treatment. A cervico-mediastinal haematoma following carotid sinus massage which required cervical drainage is presented. This is a life-threatening event demanding a high index of suspicion. A review of the literature and indications for treatment are discussed.

A meta-analysis of massage therapy research.

Massage therapy (MT) is an ancient form of treatment that is now gaining popularity as part of the complementary and alternative medical therapy movement. A meta-analysis was conducted of studies that used random assignment to test the effectiveness of MT. Mean effect sizes were calculated from 37 studies for 9 dependent variables. Single applications of MT reduced state anxiety, blood pressure, and heart rate but not negative mood, immediate assessment of pain, and cortisol level. Multiple applications reduced delayed assessment of pain. Reductions of trait anxiety and depression were MT's largest effects, with a course of treatment providing benefits similar in magnitude to those of psychotherapy. No moderators were statistically significant, though continued testing is needed. The limitations of a medical model of MT are discussed, and it is proposed that new MT theories and research use a psychotherapy perspective.

Response of atrial fibrillatory activity to carotid sinus massage in patients with atrial fibrillation.

In some cases carotid sinus massage (CSM) may induce AF, whereas it may terminate AF in others. The purpose of this study was to investigate the influence of CSM on atrial fibrillatory frequency using spectral analysis of the surface ECG. Continuous ECG recordings were made in 19 patients (12 men, 7 women, mean age 61 +/- 11 years) with AF. Unilateral CSM was performed in the standard fashion to one randomized bifurcation of the carotid artery at a time. Ventricular rate and fibrillatory frequency were assessed in 30-second ECG segments at baseline and during CSM. The frequency content of the fibrillatory baseline was quantified using digital signal processing (filtering, subtraction of averaged QRST complexes, and Fourier transformation). CSM resulted in a relative change in fibrillatory frequency of 4.5 +/- 3.9% (range 0%-13%). In 8 (42%) patients an increase in fibrillatory frequency was found (6.4 +/- 0.5 vs 6.8 +/- 0.5 Hz, P = 0.012). In 9 (47%) patients a decrease in fibrillatory frequency occurred (6.5 +/- 0.8 vs 6.1 +/- 0.8 Hz, P = 0.008) without AF termination. The remaining two patients showed no change in fibrillatory frequency. CSM on the contralateral side after 2 minutes produced fibrillatory frequency changes in the same direction in all patients with a good reproducibility in its magnitude (r = 0.59, P = 0.05). Calcium channel blockers were more frequently used (78% vs 25%, P = 0.044) in patients with a decrease in fibrillatory frequency compared to patients with a frequency increase. There were no significant changes in ventricular rate during CSM. In conclusion, two different responses of atrial fibrillatory frequency to CSM were found. This might explain why CSM may facilitate AF induction in some cases and AF termination in others. Calcium channel blocker treatment may prevent an increase in fibrillatory frequency provoked by CSM suggesting a blunted electrical remodeling process.

How reproducible is the cardioinhibitory response to carotid sinus massage in fallers?

AIMS: To ascertain the reproducibility of the cardioinhibitory subtype of carotid sinus hypersensitivity (CICSH) in fallers. METHODS AND RESULTS: One hundred and seventy-five subjects with CICSH and unexplained or recurrent falls were randomized to pacemaker implantation or control. Sixty-four control subjects (61% female, mean age 71.8 years, median 2 falls in the previous year) completed one-year follow-up and had carotid sinus massage (CSM) performed on 4 occasions (twice before randomization, at 6 months and 1 year following randomization). CSM was performed sequentially on the right and then left sides, initially supine and then upright at 70 degrees head-up tilt by the same investigator. On each occasion CSM was discontinued once CICSH was demonstrated. CICSH was demonstrated on 82% of occasions, 75% on right CSM and 77% whilst the subject was supine. Before randomization, and at 6 months and 1 year, 91%, 67%, and 70% of subjects had reproducible CICSH respectively. Half had CICSH on all 4 occasions. Only 17% had a consistent response on the same side in the same position. CONCLUSIONS: In the majority of subjects CICSH is reproducible and this is more likely shortly after the initial response. However the cardioinhibitory response to CSM is inconsistent both in side elicited and subject position.

Noninvasive gene delivery to the liver by mechanical massage.

With the recent completion of the human genome project and the tremendous growth of biotechnology, the desire to extract information concerning gene expression, protein level, subcellular localization, and functionality in the liver will demand the development of efficient gene transfer to this organ with minimal toxicity. In this report, we show that significant gene expression in the liver could be achieved by simple mechanical massage after intravenous injection of naked plasmid DNA into mice. This method is simple, highly reproducible, repeatable, and, more importantly, free of toxicity. Hepatic gene transfer with hepatocyte growth factor (HGF) plasmid DNA prevented endotoxin-induced lethal fulminant hepatic failure, leading to dramatically enhanced survival in mice.

Positive Touch and massage in the neonatal unit: a British approach.

There is now a general trend towards a more baby friendly, family centred approach in the Neonatal Unit. Aspects of that approach-including positive touch and massage- are gaining in popularity. This has caused much debate due to the ambiguity surrounding the implementation and validity of the interventions. Here the impact of these complementary practices (not to be confused with complementary therapies) is discussed. A review of the author's approach and potential guidelines for implementation is provided.

Certification examinations for massage therapists: a psychometric analysis.

OBJECTIVE: To describe the components of the Alberta Registered Massage Therapists Society (ARMTS) examination and their psychometric properties. METHODS: All 3 components of the ARMTS examination (knowledge, clinical judgement, and clinical skills) were administered to 112 candidates. The examination consisted of 2 written components (140 multiple-choice questions on basic science knowledge and 60 multiple-choice questions on clinical judgment) and a clinical competency assessment of the following practical skills with standardized patients: (1) taking a case history, (2) assessing physical condition, and (3) treating the condition. All components of the examination were criterion-referenced with the methods of minimum performance level (MPL). RESULTS: The internal consistency reliability coefficients (Cronbach alpha) ranged from 0.60 to 0.88 for all test components. The descriptive statistics, performance levels, and reliability estimates indicate that the examination is functioning well. Concurrent, criterion-related validity evidence was provided by correlations between the examination components that ranged from r = 0.24 (P <.05) to r = 0.78 (P <.01). Factor analysis produced 3 factors: information processing, clinical treatment, and follow-up management. CONCLUSIONS: The results provide evidence of adequate-to-good internal consistency reliability and content validity. Empirical validity evidence based on concurrent, criterion-related measures is provided by the correlational analysis. The significant correlations indicate that although performance is related across the examination, the various components do assess unique and independent domains. This is further supported by the results of the factor analysis that provide evidence for discriminant validity of the measures (ie, they discriminate between domains of measurement such as information processing, treatment, and basic knowledge). Taken together, these results indicate that the ARMTS examination has evidence for both reliability and validity.

Transcutaneous electrical nerve stimulation for low back pain. A comparison of TENS and massage for pain and range of motion.

Patients with acute or chronic low back pain were treated in a double-blind study that compared transcutaneous electrical nerve stimulation at intense levels and gentle, mechanically administered massage. Transcutaneous electrical nerve stimulation produced significantly greater pain relief, based on two measures of the McGill Pain Questionnaire, and significant improvement in straight leg raising. There were no significant differences between the two groups in backflexion scores. Pain-relief scores and range-of-motion scores were significantly correlated. The results indicate that pain-relief scores provide valuable information and can easily be obtained from patients for whom pain is a major symptom.

Contrasts between intrathoracic pressures during external chest compression and cardiac massage.

Pressures were measured in the right atrium, thoracic aorta, and pleural space during conventional cardiopulmonary resuscitation (CPR) and simultaneous ventilation compression cardiopulmonary resuscitation (SVC-CPR) in dogs, pigs, and a baboon. During both forms of closed chest resuscitation, the changes in atrial and aortic pressures were virtually identical over a range of 0-90 mm Hg and essentially equaled the change in pleural pressure measured at the most lateral portion of the chest cavity. During internal cardiac massage, there was no consistent relationship between right atrial and aortic pressures. However, even after the chest had been opened, the hemodynamics of external chest compression could be restored by the creation of a closed, air filled cavity surrounding the heart and great vessels. Thus, elevation of intrathoracic pressure, not direct cardiac compression, is essential to and determine circulation of blood during CPR.

The effects of therapeutic back massage on psychophysiologic variables and immune function in spouses of patients with cancer.

BACKGROUND: Spouses of patients with cancer are at risk for stress-related disorders and may experience a reduction in immune function. Therapeutic back massage (TBM) has been shown to enhance relaxation and thus, may reduce stress associated with caring for an ill partner. OBJECTIVES: To determine if TBM's influences on psychosocial, physiologic, and immune function variables in spouses of patients with cancer, and explore the relationships between psychosocial variables and immune function in spouses of patients with cancer. METHODS: This group experimental design measured the effects of a 20-minute TBM at three time points (preintervention, immediately postintervention, 20 minutes postintervention) on spouses of patients with cancer (N= 42) randomly assigned to either the experimental or control group. The major dependent variables including natural killer cell activity (NKCA), heart rate, systolic and diastolic blood pressure, mood, and perceived stress were measured at the three time points to examine the effects of TBM. Data collected on measures of mood and perceived stress were correlated with NKCA to examine their relationships. Prior to hypotheses testing, data collected on measures of depressive mood, loneliness, marital disruption, and health practices were also correlated with NKCA to ascertain any possible confounding variables. RESULTS: Two-way repeated measures analysis of variance tests determined the effects of TBM over the two postintervention time points and resulted in significant group x time interactions on mood (F [2, 40]= 14.61, p=.0005) and perceived stress (F [2, 40]= 28.66, p=.001). Significant inverse relationships were found between mood and NKCA (r= -.41, p=.009, N= 42) and perceived stress and NKCA (r= -.37, p=.017, N= 42). DISCUSSION: Findings suggest that TBM may enhance mood and reduce perceived stress in this population. Insight was gained into the psycho-immunologic relationships studied.

The effect of massage treatment of prostatic congestion on the prostatic size and secretion of citric acid.

In this study, 25 men, referred to our clinic for diagnosis and therapy of infertility were included. All had enlarged prostates. They were given 10 sessions of prostatic massage during 3--4 weeks and the fluid expressed was analysed for citric acid. The hypertrophy was seen to recede in almost all cases. Citric acid concentrations fell in only 6/25 cases analysed. In all the others, values did not fall and remained relatively stable. There was no apparent relationship between reduction of prostatic volume and the pattern of citric acid secretion.
