Old age does not negate good cerebral outcome after cardiopulmonary resuscitation: analyses from the brain resuscitation clinical trials. The Brain Resuscitation Clinical Trial I and II Study Groups.

OBJECTIVE: To assess survival after cardiac arrest and to determine whether age is an independent determinant of late mortality or poor neurologic outcome. DESIGN: Analyses using results of Brain Resuscitation Clinical Trial I (1979 to 1984) and Brain Resuscitation Clinical Trial II (1984 to 1989), two randomized, double-blind studies of outcome following cardiac arrest. SETTING: A multicenter study in 12 acute care hospitals in nine countries (Brain Resuscitation Clinical Trial I), and 24 hospitals in eight countries (Brain Resuscitation Clinical Trial II). PATIENTS: A total of 774 patients who were initially comatose after successful resuscitation from cardiac arrest. The analyses include both in- and out-of-hospital cardiac arrests. RESULTS: The 6-month mortality rate for the entire group was 81%. Mortality rate was 94% for the oldest group (> 80 yrs) compared with 68% for the youngest group (< or = 45 yrs) (p < .01). Other independent predictors of mortality were history of diabetes mellitus, inhospital arrests, arrest time of > 5 mins, history of congestive heart failure, a noncardiac cause of arrest, and cardiopulmonary resuscitation time of > 20 mins. Of the 774 patients, 27% recovered good neurologic function. There was no statistically significant difference in neurologic recovery rates by age. Multivariate analysis showed that independent predictors of good neurologic recovery were: no history of diabetes mellitus, a cardiac cause of arrest, short arrest time, and short cardiopulmonary resuscitation time. CONCLUSION: Increasing age was a factor in postresuscitation mortality, but was not an independent predictor of poor neurologic outcome.

International Guidelines for Neonatal Resuscitation: An excerpt from the Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care: International Consensus on Science. Contributors and Reviewers for the Neonatal Resuscitation Guidelines.

The International Guidelines 2000 Conference on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiac Care (ECC) formulated new evidenced-based recommendations for neonatal resuscitation. These guidelines comprehensively update the last recommendations, published in 1992 after the Fifth National Conference on CPR and ECC. As a result of the evidence evaluation process, significant changes occurred in the recommended management routines for: * Meconium-stained amniotic fluid: If the newly born infant has absent or depressed respirations, heart rate <100 beats per minute (bpm), or poor muscle tone, direct tracheal suctioning should be performed to remove meconium from the airway. * Preventing heat loss: Hyperthermia should be avoided. * Oxygenation and ventilation: 100% oxygen is recommended for assisted ventilation; however, if supplemental oxygen is unavailable, positive-pressure ventilation should be initiated with room air. The laryngeal mask airway may serve as an effective alternative for establishing an airway if bag-mask ventilation is ineffective or attempts at intubation have failed. Exhaled CO(2) detection can be useful in the secondary confirmation of endotracheal intubation. * Chest compressions: Compressions should be administered if the heart rate is absent or remains <60 bpm despite adequate assisted ventilation for 30 seconds. The 2-thumb, encircling-hands method of chest compression is preferred, with a depth of compression one third the anterior-posterior diameter of the chest and sufficient to generate a palpable pulse. * Medications, volume expansion, and vascular access: Epinephrine in a dose of 0.01-0.03 mg/kg (0.1-0.3 mL/kg of 1:10,000 solution) should be administered if the heart rate remains <60 bpm after a minimum of 30 seconds of adequate ventilation and chest compressions. Emergency volume expansion may be accomplished with an isotonic crystalloid solution or O-negative red blood cells; albumin-containing solutions are no longer the fluid of choice for initial volume expansion. Intraosseous access can serve as an alternative route for medications/volume expansion if umbilical or other direct venous access is not readily available. * Noninitiation and discontinuation of resuscitation: There are circumstances (relating to gestational age, birth weight, known underlying condition, lack of response to interventions) in which noninitiation or discontinuation of resuscitation in the delivery room may be appropriate.

["Topless" cardiopulmonary resuscitation? Should heart-lung resuscitation be preformed without artificial resuscitation?].

A paper published in various US journals on Emergency Medicine in 1997, has raised considerable concerns. The authors question if it is justified to continue to recommend initial ventilation as part of basic CPR when performed by lay-bystanders. A few aspects need to be discussed and some questions have to be answered before any changes in the current recommendations may even be considered: e.g. 1. How convincing does the available evidence support the following hypotheses: 1.1. Lay CPR without mouth-to-mouth-ventilation provides better outcome after cardiac arrest than lay CPR with mouth-to-mouth-ventilation. 1.2. Endotracheal intubation may be detrimental in patients suffering from hemodynamic compromises, particularly from VF. 2. Is it scientifically and ethically acceptable to design and perform prospective randomized controlled trials (RCTs) to evaluate the efficacy of those components of BCLS and ACLS which have in accordance with AHA-, ERC Guidelines and ILCOR Statements in the past been applied in millions of cardiac arrest victims and have obviously enabled the patients to lead a meaningful life after survival; under conditions of the proposed study design patients of the study group would be left without the treatment option ventilation, thus diminishing their chances of survival. Ad 1: The arguments presented by the authors are hardly convincing. The authors themselves state elsewhere that reluctance to perform mouth-to-mouth-ventilation should not represent a major problem because most cardiac arrests of cardiac etiology occur at home and in the presence of a relative or friend. Moreover, unreliable recommendations for mouth-to-mouth-ventilation (AHA), lack of training, retention of skills and knowledge, and a deficit in motivation include the main causes of the disappointingly low figures of bystander CPR worldwide. This situation cannot be improved simply by eliminating a lifesaving component of CPR-ventilation. Instead, the proposal to abandon the administration of unreasonably high ventilation volumes (800-1200 ml/breath) from the present guidelines and to recommend volumes ranging from 400-500 ml/breath recently made by the ERC should be given serious consideration. Furthermore, equipment and training manikins need to be adapted to these more reasonable volumes. Independently of the mechanisms of slow decreases in SaO2 after cardiac arrest (provided no compressions are performed) independently of gasping, ventilatory effects of standard compression or ACD-HCPR in the absence of mouth-to-mouth-ventilation, it is essential to realise that the patient's airways need to be maintained open at all times (this is unlike animal experiments where the airways are primarily kept open by the respective tissue structures): The minimum requirement of First Responder CPR is the guarantee that open airways are maintained. It may possibly be discussed if the present sequence of ABC might be changed to CAB, a practice adopted in the Netherlands many years ago, however, outcome trials an CAB have not been published to date. In addition, greater demands should be made of training requirements in BLS, attendance of refresher courses should be required, and other groups of the population should be included into these programmes than only relatives or friends of patients at risk of a cardiac arrest. The programmes need to be made mandatory for greater variety of groups and individuals to increase the efficacy and efficiency of bystander resuscitation. The hypotheses made by the above-mentioned authors are neither scientifically nor ethically acceptable. Ad 2: Pepe's argument regarding the efficacy of endotracheal intubation (ETI) in VF-patients has not been scientifically proven and lacks conclusive evidence. ETI serves to protect the airways and lungs against aspiration of regurgitated material and to facilitate artificial ventilation including PEEP, both under anaesthesia and resuscitation. The efficacy of ETI in the OR has long b

A comparison of standard cardiopulmonary resuscitation and active compression-decompression resuscitation for out-of-hospital cardiac arrest. French Active Compression-Decompression Cardiopulmonary Resuscitation Study Group.

BACKGROUND: We previously observed that short-term survival after out-of-hospital cardiac arrest was greater with active compression-decompression cardiopulmonary resuscitation (CPR) than with standard CPR. In the current study, we assessed the effects of the active compression-decompression method on one-year survival. METHODS: Patients who had cardiac arrest in the Paris metropolitan area or in Thionville, France, more than 80 percent of whom had asystole, were assigned to receive either standard CPR (377 patients) or active compression-decompression CPR (373 patients) according to whether their arrest occurred on an even or odd day of the month, respectively. The primary end point was survival at one year. The rate of survival to hospital discharge without neurologic impairment and the neurologic outcome were secondary end points. RESULTS: Both the rate of hospital discharge without neurologic impairment (6 percent vs. 2 percent, P=0.01) and the one-year survival rate (5 percent vs. 2 percent, P=0.03) were significantly higher among patients who received active compression-decompression CPR than among those who received standard CPR. All patients who survived to one year had cardiac arrests that were witnessed. Nine of 17 one-year survivors in the active compression-decompression group and 2 of 7 in the standard group, respectively, initially had asystole or pulseless electrical activity. In 12 of the 17 survivors who had received active compression-decompression CPR, neurologic status returned to base line, as compared with 3 of 7 survivors who had received standard CPR (P=0.34). CONCLUSIONS: Active compression-decompression CPR performed during advanced life support significantly improved long-term survival rates among patients who had cardiac arrest outside the hospital.

Active chest compression-decompression for cardiopulmonary resuscitation.

BACKGROUND: Active compression-decompression cardiopulmonary resuscitation (ACD CPR) uses a hand-held suction device, applied mid sternum, to compress the chest then actively decompress the chest after each compression. Randomised controlled trials on use of active compression decompression cardiopulmonary resuscitation have results which are discordant. OBJECTIVES: To determine clinical effects and safety of active compression-decompression cardiopulmonary resuscitation compared with standard manual cardiopulmonary resuscitation (STR). SEARCH STRATEGY: We searched the Cochrane Heart Group Specialised register (April 2001), the Cochrane library, MEDLINE and EMBASE. We checked the reference list of retrieved articles and contacted enterprises manufacturing the active decompression devices. SELECTION CRITERIA: All randomized or quasi-randomized studies comparing active compression-decompression cardiopulmonary resuscitation compared with standard manual cardiopulmonary resuscitation in adults with a cardiac arrest who received cardiopulmonary resuscitation by a trained medical or paramedical team. DATA COLLECTION AND ANALYSIS: Data were independently extracted. All data were analysed on an intention-to-treat basis. The authors of the primary studies were contacted for more information when needed. Studies were cumulated, if appropriate, and pooled relative risk (RR) estimated. Subgroup analysis according to setting (out of hospital or in hospital) and attending team composition (with physician or paramedic only) were predefined. MAIN RESULTS: Twelve trials were included: 10 were in out-of-hospital settings, one set in-hospital only and one had both in-hospital and out-of-hospital components. Allocation concealment was adequate in 4 trials. The two in-hospital studies were very different in quality (A and C) and size (773 and 53 patients). Both found no differences between ACD CPR and STR in any outcome. Trials conducted in out-of-hospital settings cumulated 4162 patients. There were no differences between ACD CPR and STR for mortality either immediately (RR 0.98 [95% CI 0.94 - 1.03]) or at hospital discharge (RR 0.99 [95% CI 0.98 - 1.01]). The pooled RR of neurological impairment, any severity, was 1.71 [95% CI 0.90 - 3.25], with a non-significant trend to more frequent severe neurological damage in survivors of ACD CPR (RR 3.11 [95% CI 0.98 - 9.83]). However, assessment of neurological outcome was limited and there were few patients with neurological damage. There was no difference between ACD CPR and STR with regard complications such as rib or sternal fractures, pneumothorax or hemothorax (RR 1.09 [95% CI 0.86 - 1.38]). Skin trauma and ecchymosis were more frequent with ACD CPR. REVIEWER'S CONCLUSIONS: Active chest compression-decompression in patients with cardiac arrest is not associated with clear benefit.

Resuscitation of the newly born infant: an advisory statement from the Pediatric Working Group of the International Liaison Committee on Resuscitation.

The International Liaison Committee on Resuscitation (ILCOR), with representation from North America, Europe, Australia, New Zealand, Africa, and South America, was formed in 1992 to provide a forum for liaison between resuscitation organizations in the developed world. This consensus document on resuscitation extends previously published ILCOR advisory statements on resuscitation to address the unique and changing physiology of the newly born infant within the first few hours following birth and the techniques for providing advanced life support. After careful review of the international resuscitation literature and after discussion of key and controversial issues, consensus was reached on almost all aspects of neonatal resuscitation, and areas of controversy and high priority for additional research were delineated. Consensus on resuscitation for the newly. born infant included the following principles. (i) Personnel trained in the basic skills of resuscitation should be in attendance at every delivery. A minority (fewer than 10%) of newly born infants require active resuscitative interventions to establish a vigorous cry and regular respirations, maintain a heart rate greater than 100 beats per minute (bpm), and maintain good color and tone. (ii) When meconium is present in the amniotic fluid, it should be suctioned from the hypopharynx on delivery of the head. If the meconium-stained newly born infant has absent or depressed respirations, heart rate, or muscle tone, residual meconium should be suctioned from the trachea. (ii) Attention to ventilation should be of primary concern. Assisted ventilation with attention to oxygen delivery, inspiratory time, and effectiveness judged by chest rise should be provided if stimulation does not achieve prompt onset of spontaneous respirations and/or the heart rate is less than 100 bpm. (iv) Chest compressions should be provided if the heart rate is absent or remains less than 60 bpm despite adequate assisted ventilation for 30 s. Chest compressions should be coordinated with ventilations at a ratio of 3:1 and a rate of 120 'events' per minute to achieve approximately 90 compressions and 30 rescue breaths per minute. (v) Epinephrine should be administered intravenously or intratracheally if the heart rate remains less than 60 bpm despite 30 s of effective assisted ventilation and chest compression circulation. Common or controversial medications (epinephrine, volume expansion, naloxone, bicarbonate), special resuscitation circumstances affecting care of the newly born, continuing care of the newly born after resuscitation, and ethical considerations for initiation and discontinuation of resuscitation are discussed. There was agreement that insufficient data exist to recommend changes to current guidelines regarding the use of 21% versus 100% oxygen, neuroprotective interventions such as cerebral hypothermia, use of a laryngeal mask versus endotracheal tube, and use of high-dose epinephrine. Areas of controversy are identified, as is the need for additional research to improve the scientific justification of each component of current and future resuscitation guidelines.

Resuscitation after uncontrolled venous hemorrhage: Does increased resuscitation volume improve regional perfusion?

BACKGROUND: Recent studies have questioned the use of aggressive fluid resuscitation after uncontrolled arterial hemorrhage until the bleeding is controlled. However, it remains unknown whether resuscitation after hemorrhage from a venous origin (usually nonaccessible to surgical intervention) has any beneficial or deleterious effects on regional perfusion. The aim of this study, therefore, was to determine whether increased volume of fluid resuscitation after uncontrolled venous hemorrhage improves hemodynamic profile and regional perfusion in various tissues. MATERIALS AND METHODS: After methoxyflurane anesthesia and midline laparotomy, both lumbar veins in the rat were severed, which resulted in lowering the mean arterial blood pressure to approximately 40 mm Hg. This pressure was maintained for 45 minutes by allowing further bleeding from the lumbar veins. The abdominal incision was then closed in layers and the animals received either 0, 10, or 30 mL of lactated Ringer's solution intravenously over a period of 60 minutes. Cardiac output and regional blood flow were determined by radioactive microspheres immediately or at 1.5 hours after the completion of resuscitation. RESULTS: Fluid resuscitation with 10 or 30 mL lactated Ringer's solution increased mean arterial blood pressure and cardiac output immediately after resuscitation compared with the nonresuscitated animals. At both time points, regional perfusion in the heart, kidney and intestines remained significantly decreased compared with the sham values, irrespective of the volume of fluid resuscitation. Moreover, no further improvements in hemodynamics or regional perfusion occurred when volume resuscitation was increased from 10 mL to 30 mL. Total hepatic blood flow, however, increased with 10 mL lactated Ringer's solution compared with the other hemorrhage groups and the increase was evident even at 1.5 hours after resuscitation. CONCLUSIONS: Fluid resuscitation after uncontrolled venous bleeding transiently increased cardiac output and mean arterial blood pressure compared with nonresuscitated animals. Moderate fluid administration, i.e., 10 mL, however, did increase total hepatic blood flow. In contrast, increasing the resuscitation volume to 30 mL did not improve hemodynamic parameters or regional perfusion. Thus moderate instead of no resuscitation or larger volume of resuscitation is recommended in an uncontrolled model of venous hemorrhage.

Outcome of adult cardiopulmonary resuscitations at a tertiary referral center including results of "limited" resuscitations.

BACKGROUND: The results of in-hospital resuscitations may depend on a variety of factors related to the patient, the environment, and the extent of resuscitation efforts. We studied these factors in a large tertiary referral hospital with a dedicated certified resuscitation team responding to all cardiac arrests. METHODS: Statistical analysis of 445 prospectively recorded resuscitation records of patients who experienced cardiac arrest and received advanced cardiac life support resuscitation. We also report the outcomes of an additional 37 patients who received limited resuscitation efforts because of advance directives prohibiting tracheal intubation, chest compressions, or both. MAIN OUTCOME MEASURES: Survival immediately after resuscitation, at 24 hours, at 48 hours, and until hospital discharge. RESULTS: Overall, 104 (23%) of 445 patients who received full advanced cardiac life support survived to hospital discharge. Survival was highest for patients with primary cardiac disease (30%), followed by those with infectious diseases (15%), with only 8% of patients with end-stage diseases surviving to hospital discharge. Neither sex nor age affected survival. Longer resuscitations, increased epinephrine and atropine administration, multiple defibrillations, and multiple arrhythmias were all associated with poor survival. Patients who experienced arrests on a nursing unit or intensive care unit had better survival rates than those in other hospital locations. Survival for witnessed arrests (25%) was significantly better than for nonwitnessed arrests (7%) (P =.005). There was a disproportionately high incidence of nonwitnessed arrests during the night (12 AM to 6 AM) in unmonitored beds, resulting in uniformly poor survival to hospital discharge (0%). None of the patients whose advance directives limited resuscitation survived. CONCLUSIONS: Very ill patients in unmonitored beds are at increased risk for a nonwitnessed cardiac arrest and poor resuscitation outcome during the night. Closer vigilance of these patients at night is warranted. The outcome of limited resuscitation efforts is very poor.

Changes in expired end-tidal carbon dioxide during cardiopulmonary resuscitation in dogs: a prognostic guide for resuscitation efforts.

Expired end-tidal carbon dioxide (PCO2) measurements made during cardiopulmonary resuscitation have correlated with cardiac output and coronary perfusion pressure when wide ranges of blood flow are included. The utility of such measurements for predicting resuscitation outcome during the low flow state associated with closed chest cardiopulmonary resuscitation remains uncertain. Expired end-tidal PCO2 and coronary perfusion pressures were measured in 15 mongrel dogs undergoing 15 min of closed chest cardiopulmonary resuscitation after a 3 min period of untreated ventricular fibrillation. In six successfully resuscitated dogs, the mean expired end-tidal PCO2 was significantly higher than that in nine nonresuscitated dogs only after 14 min of cardiopulmonary resuscitation (6.2 +/- 1.2 versus 3.4 +/- 0.8 mm Hg; p less than 0.05). No differences in expired end-tidal PCO2 values were found at 2, 7 or 12 min of cardiopulmonary resuscitation. A significant decline in end-tidal PCO2 levels during the resuscitation effort was seen in the nonresuscitated group (from 6.3 +/- 0.8 to 3.4 +/- 0.8 mm Hg; p less than 0.05); the successfully resuscitated group had constant PCO2 levels throughout the 15 min of cardiac arrest (from 6.8 +/- 1.1 to 6.2 +/- 1.2 mm Hg). Changes in expired PCO2 levels during cardiopulmonary resuscitation may be a useful noninvasive predictor of successful resuscitation and survival from cardiac arrest.

[A survey of 3,303 6th-year medical students from 36 universities concerning knowledge of resuscitation--more than 80% of medical students can not perform standard cardiopulmonary resuscitation?].

Questionnaires on knowledge of resuscitation were distributed to 3,303 6th-year medical school students from 36 universities. The questionnaire included 13 questions based on the 1992 guidelines for cardiopulmonary resuscitation. From the 13 questions, each student was instructed to select 6 questions concerning assessment of consciousness level, method for confirming respiration, method for securing the airway, method for confirming circulation, pressure points for cardiac massage, and the ratio of respiration and cardiac massage. If all of these six questions could not be answered correctly, it was considered that the student was not able to perform resuscitation according to the guidelines. At least one incorrect answer was given to the six questions by 84% of students, indicating that most medical students are not able to actually perform standard resuscitation. Possible reasons for these results may be the lack of desire on the part of students to master resuscitation, confusion over new findings concerning resuscitation and guideline, insufficient understanding of the difference between the guidelines and new findings by educators, and restricted teaching time for resuscitation. Possible ways to improve the situation include efforts to make students more responsible to master resuscitation, efforts to enhance students' desire to learn, adoption of more practical education, inclusion of such questions in graduation examinations and the national examination for a medical license, adherence by educators to the guidelines, and efforts by educators to make a clear distinction between the guidelines and new findings. With new guidelines for cardiopulmonary resuscitation due out in the year 2000, methods for teaching resuscitation should be reconsidered in order to ensure that all medical students can competently perform resuscitation.

Effects of blood resuscitation versus dextran resuscitation after hemorrhage on intrinsic myocardial function.

BACKGROUND: Myocardial function is altered by many factors present in hemorrhaged and resuscitated animals. The purpose of this study was to determine whether resuscitation after a short period of hemorrhagic shock, which by itself did not alter intrinsic cardiac function, causes dysfunction. METHODS: Guinea pigs were instrumented to measure blood pressure and cardiac output, and several days later 50% of their blood volume was removed at a rate of 1 mL/min. Some animals were resuscitated with the shed blood and some with 6% dextran. Hearts were studied 1 or 24 hours after resuscitation. RESULTS: Isolated hearts from animals after 1 hour of resuscitation demonstrated dysfunction whether resuscitated with blood or dextran, although dysfunction was more severe with blood resuscitation. By 24 hours, dysfunction was essentially reversed. CONCLUSIONS: Resuscitation after hemorrhagic shock caused injury to the myocardium independent of the hemorrhage. Blood resuscitation resulted in greater dysfunction than did resuscitation with dextran.

Decisions to terminate resuscitation. Resuscitation Committee.

To gain more insight into decision making around the termination of resuscitation (CPR), we studied factors which influenced the time before discontinuing resuscitation, and the criteria on which those decisions were based. These criteria were compared with those of the European Resuscitation Council (ERC) and the American Heart Association (AHA). For this study, we reviewed the audiotapes of resuscitation attempts in a hospital. A total of 36 attempts were studied, involving 27 men and nine women, mean (S.D.) age 64 (18) years. A total of 19 patients received resuscitation on general wards, and 17 in the emergency room after an out-of-hospital circulatory arrest. The median interval time (range) from start to termination was 33 min (8-81 min). Results from multiple linear regression showed that a delay greater than 5 min in first advanced life support measures, drawing a sample for biochemical analysis, and the patient's response shown by return of spontaneous circulation were independently associated with the time of terminating resuscitation. The team used a number of criteria which can be found in the guidelines of the ERC and the AHA, but also used additional criteria. The ERC and the AHA criteria were not sufficient to cover all termination decisions. We conclude that the point in time to terminate resuscitation is not always rationally chosen. Updating of the current guidelines for terminating resuscitation and training resuscitation teams to use these guidelines is recommended.

Impact of do-not-resuscitate legislation on the use of cardiopulmonary resuscitation in three teaching hospitals.

Under New York State's unique do-not-resuscitate law, patients admitted to a hospital are assumed to consent to cardiopulmonary resuscitation unless a do-not-resuscitate order has been written in accordance with specific stipulations. This study was undertaken to determine if the law would significantly change the use of cardiopulmonary resuscitation. The charts of 952 patients who died on the medical services of Bellevue, New York University, and New York Veterans hospitals during the 12-month periods before and after the law went into effect were reviewed. The proportion of patients undergoing cardiopulmonary resuscitation was determined. To take into account the effects of potential confounders (ie, hospital, sex, race or ethnic group, age, diagnosis), a multiple logistic regression analysis was performed. The relative risk for cardiopulmonary resuscitation was found to be 0.81, (95% confidence interval: 0.59-1.10) after the law as compared with before, which was not statistically significant. Although patients with chronic or potentially reversible illness were much more likely than those with hopeless illness to undergo cardiopulmonary resuscitation (relative risk of 7.08 [3.23-15.54] and 12.89 [8.71-19.07], respectively), the data failed to show that the law had an impact on the use of cardiopulmonary resuscitation in any of the disease categories. Total use of formal do-not-resuscitate orders increased from 32.7% to 83.9% (p less than .0001), although at Bellevue, where documentation was high before the law, no further increase occurred.(ABSTRACT TRUNCATED AT 250 WORDS)

Active compression-decompression resuscitation: effect on resuscitation success after in-hospital cardiac arrest.

OBJECTIVES: The purpose of this study was to test the hypothesis that active compression-decompression would improve resuscitation success in human subjects after cardiac arrest. BACKGROUND: Active compression-decompression cardiopulmonary resuscitation is a new method that improves cardiopulmonary hemodynamic function in animal models and humans after cardiac arrest. METHODS: We conducted a prospective randomized clinical trial in patients with in-hospital cardiac arrest. Patients were assigned to receive standard manual or active compression-decompression cardiopulmonary resuscitation. The primary study end points were spontaneous return of circulation, 24-h survival and survival to hospital discharge. RESULTS: Fifty-three consecutive patients after cardiac arrest undergoing 64 resuscitation attempts were studied (30 women, 23 men; mean [+/- SD] age 71 +/- 13 years, range 38 to 96). Spontaneous return of circulation was observed in 24 (47%) of 53 patients and was increased in patients receiving active compression-decompression compared with those receiving standard manual cardiopulmonary resuscitation (15 [60%] of 25 vs. 9 [32%] of 28, respectively, p = 0.042); 24-h survival was increased (12 [48%] of 25 vs. 6 [21%] of 28, respectively, p = 0.041); and there was a trend toward improved survival to hospital discharge (6 [24%] of 25 vs. 3 [11%] of 28, respectively, p = 0.198) when active compression-decompression was compared with standard manual cardiopulmonary resuscitation. CONCLUSIONS: Active compression-decompression cardiopulmonary resuscitation improves return of spontaneous circulation and 24-h survival after in-hospital cardiac arrest. Active compression-decompression cardiopulmonary resuscitation appears to be a beneficial adjunct to standard manual cardiopulmonary resuscitation.
