Three patients who were resuscitated with external cardiac massage are reported, who recovered completely without any neurological damage. In all cases, cardiac and respiratory resuscitation was started not later than 2 minutes after arrest-respiration and heart beat returned within 7 minutes. Hypothermia was done in two cases after resuscitation to promote easier recovery. All cases recovered completely without any neurological damage or complications, thus showing a 100% survival rate. Closed cardiac massage proved to be effective in these cases of cardiac arrest.

The purpose of this study was to identify the effects of foot massage on the stress of student nurses in clinical practice. The research design was a nonequivalent control group pretest-posttest design. The subjects of this study were 52 student nurses from three junior colleges and one university. The subjects were assigned to one of two groups:the experimental group(26 students), and the control group(26 students). The study was conducted from October to November 1999. For the experimental group the foot massage was performed once a day for 3 days, starting from the first day of clinical practice. Subjects' mood, fatigue, blood pressure and pulse rate were measured as dependent variables. The Instrument for mood and fatigue state was a 100mm visual analogue scale. For the experimental group pre and post tests were done just before and after every 3 foot massages and on the 7th clinical practice day. For the control group pretest was done on 1st clinical day and posttest was done on clinical practice 7th day. The data was analyzed by the t-test and paired t-test and the results are summarized as follows: 1. The mood state scores were significantly higher for the experimental group as compared to the control group after the foot massage(t=13.73, p<0.001). 2. The fatigue state scores were significantly lower for the experimental group as compared to the control group after the foot massage(t=8.69, p<0.001). 3. The systolic blood pressure was significantly different between the experimental group and the control group after the foot massage(t=3.0073, p<0.01). 4. The diastolic blood pressure was not significantly different between the experiment group and the control group after the foot massage. 5. The pulse rate was not significantly different between the experiment group and the control group after foot massage. 6. The mood state scores on the 1st, 2nd, 3rd massage day was significantly improved right after the foot massage. 7. The fatigue state scores on the 1st, 2nd, 3rd massage day were significantly lower right after the foot massage. 8. Systolic blood pressure on the 1st and 2nd massage day was significantly decreased right after the foot massage. Diastolic blood pressure and pulse rate were decreased right after massage but the change was not statistically significant. On the basis of the above findings, this study suggests that foot massage can be an effective stress relieving method for student nurses in clinical practice.

BACKGROUND: Cardiopulmonary resuscitation (CPR) has been practised since the introduction of external cardiac massage in 1960. Observed results of in-hospital CPR in many published studies vary greatly. Data on survival has called attention to patient-related factors, lack of medical personnel training and delay in initiation of CPR. We evaluated the results of CPR attempted in a single institute in Korea. SUBJECTS: Our subjects were patients in whom CPR was instituted in our hospital with activation of the emergency call system between August 1, 1995 and December 31, 1997 (n=308, M=181, F=127, mean age=47.8+/-26.4 years). RESULTS: One hundred and ninety-eight among the 308 cases of in-hospital CPR were reviewed, excluding preventive CPR cases and CPR performed on subjects designated DNAR (Do not attempt resuscitation). Mechanism of arrest were respiraory arrest in 84 cases (42.4%), ventricular tachycardia/fibrillation in 59 (29.8%), asytole in 52 (26.3%), and electromechanical dissocaition in 3 (1.5%) in order of declining frequency. Overall survival rate at discharge was 12.6%. Among different age groups, the rates were:21.6% in the pediatric group (age<16), 12.6% in the adult group (16 < or = age <70) and 6.0% in the elderly group (age > or = 70). Survival outcomes associated with mechanism of arrest were:11.9% for respiratory arrest, 15.3% for ventricular tachycardia/fibrillation and 9.6% for asystole. No significant difference in survival was found between mechanisms of arrest. Successful outcome after CPR was significantly associated with CPR duration, showing higher wurvival rates with CPR performed for less than 15 minutes than over 15 minutes (p<0.001). CONCLUSION: Among in-hospital CPR cases, only 12.6% survive to discharge. We suggest that guidelines for performing and evaluating in-hospital CPR should be set up to improve the survival rate.

Nine cases of cardiac arrest caused by various conditions and circumstances has been reported. 1. All of them were resuscitated by external cardiac massage but one of them had very poor physical; conditions because of delay in management. 4 cases made an uncomplicated recovery and 5 cases expired. Acute and chronic hypoxia was suspected as the most commoncause of cardiac arrest in these cases. 3. Of the expired 5 cases, intravenous injection of potassium chloride was suspected as the cause in one case. Another one was due to spinal anesthesia. 4. External cardiac massage might be an excellent method of cardiopulmonary resuscitation.

A case of cardiac arrest due to left ventricular stab wound was resuscitated by open cardiac massage and surgery. The experience was concluded as follows: 1. Under light anesthesia, bleeding was controlled by immediate surgery, which might have increased the survival rate. 2. Sufficient oxygen administration and proper anti-shock therapy provided an excellent prognosis.

A 6-year-old-man with a severe pectus excavatum and marfanoid feature was admitted for the correction of pectus excavatum. Nuss procedure was recently introduced, because of its excellent effect from the cosmetic point of view. This method is that convex steel bar is inserted under the sternum through small bilateral thoracic incisions, and when it is in position, the bar is turn over, thereby correction the deformity. We experienced a case of the cardiac arrest during the rotation of a stainless steel bar. After the injection of atropine, epinephrine and the closed cardiac massage, sinus rhythm was restored. A vasovagal reflex due to the operation could be considered the possible etiology.

Cardiopulmonary resuscitation (CPR) is a series of life-saving actions that improve the chances of survival, following cardiac arrest. Successful resuscitation, following cardiac arrest, requires an integrated set of coordinated actions represented by the links in the Chain of Survival. The links include the following: immediate recognition of cardiac arrest and activation of the emergency response system, early CPR with an emphasis on chest compressions, rapid defibrillation, effective advanced life support, and integrated post-cardiac arrest care. The newest development in the CPR guideline is a change in the basic life support sequence of steps from "A-B-C" (Airway, Breathing, Chest compressions) to "C-A-B" (Chest compressions, Airway, Breathing) for adults. Also, "Hands-Only (compression only) CPR" is emphasized for the untrained lay rescuer. On the basis of the strength of the available evidence, there was unanimous support for continuous emphasis on high-quality CPR with compressions of adequate rate and depth, which allows for complete chest recoil, minimizing interruptions in chest compressions and avoiding excessive ventilation. High-quality CPR is the cornerstone of a system of care that can optimize outcomes beyond return of spontaneous circulation (ROSC). There is an increased emphasis on physiologic monitoring to optimize CPR quality, and to detect ROSC. A comprehensive, structured, integrated, multidisciplinary system of care should be implemented in a consistent manner for the treatment of post-cardiac arrest care patients. The return to a prior quality and functional state of health is the ultimate goal of a resuscitation system of care.

A case of sudden cardiac arrest due to misplaced tracheostomy cannula was reviewed. The genera1 condition of the patient was febrile, dyspneic and acutely ill. Emergency tracheostomy was performed under ketamine-halothane endotracheal anesthesia. Sudden cardiac arrest was noticed when a metal cannula was inserted through the tracheostomy site by the surgeon after the tracheostomy. Immediate closed chest cardiac massage was performed successfully.
