BACKGROUND AND PURPOSE: The purpose of this study is to compare two clinical predictive rules, the pre-arrestmorbidity(PAM) index and the prognosis-after-resuscitation(PAR) score, which predict failure to survive following in-hospital cardiopulmonary resuscitation(CPR). METHOD: The study population consisted of 162 consecutive adult patients who underwent CPR at Wonju Christian Hospital over a year period. The PAM index and PAR score were calculated from the most recent data available for each variable prior to cardiac arrest. Each predictive tool was compared between the group of discharge alive and the group of in-hospital mortality. Performance of the predictive scores was also compared by receiver-operating characteristic(ROC) curves where appropriate. RESULTS: PAM index of study population was 4.39+/-2.69 and PAR score was 2.99+/-3.36. PAM index in the group of discharge alive was 1.87+/-2.79, and PAM index in the group of ih-hospital mortality was 4.51+/-2.62. PAR score in the group of discharge alive was 0.75+/-1.75, and PAR score in the group of in-hospital mortality was 3.1+/-3.4. The PAM index identified 15 patients with a score>8, while the PAR score identified 39 patients with a score>4, none of whom survived. The sensitivity of the PAR score for the prediction of failure to survive was 25%, while that of the PAM index was 10%; neither index incorrectly identified a patient as a non-survivor who eventually survived. Both of predictive methods were not significantly different in the ROC curve. CONCLUSION: Although further confirmation is necessary, PAM index and PAR score may provide useful prognostic information to physicians and patients involved with decisions about do-no- resuscitate orders.

BACKGROUND: Many physicians hesitate to discuss do-not-resuscitate (DNR) orders with patients or family members in critical situations. In the intensive care unit (ICU), delayed DNR decisions could cause unintentional cardiopulmonary resuscitation, patient distress, and substantial cost. We investigated whether the timing of DNR designation affects patient outcome in the medical ICU. METHODS: We enrolled retrospective patients with written DNR orders in a medical ICU (13 bed) from June 1, 2014 to May 31, 2015. The patients were divided into two groups: early DNR patients for whom DNR orders were implemented within 48 h of ICU admission, and late DNR patients for whom DNR orders were implemented more than 48 h after ICU admission. RESULTS: Herein, 354 patients were admitted to the medical ICU and among them, 80 (22.6%) patients had requested DNR orders. Of these patients, 37 (46.3%) had designated DNR orders within 48 hours of ICU admission and 43 (53.7%) patients had designated DNR orders more than 48 hours after ICU admission. Compared with early DNR patients, late DNR patients tended to withhold or withdraw life-sustaining management (18.9% vs. 37.2%, p = 0.072). DNR consent forms were signed by family members instead of the patients. Septic shock was the most common cause of medical ICU admission in both the early and late DNR patients (54.1% vs. 37.2%, p = 0.131). There was no difference in in-hospital mortality (83.8% vs. 81.4%, p = 0.779). Late DNR patients had longer ICU stays than early DNR patients (7.4 ± 8.1 vs. 19.7 ± 19.2, p < 0.001). CONCLUSIONS: Clinical outcomes are not influenced by the time of DNR designation in the medical ICU. The late DNR group is associated with a longer length of ICU stay and a tendency of withholding or withdrawing life-sustaining treatment. However, further studies are needed to clarify the guideline for end-of-life care in critically ill patients.

PURPOSE: We analyzed the characteristics and outcome of pediatric out-of-hospital cardiac arrest. METHODS: Pediatric out-of-hospital cardiac arrest from January 2000 to December 2005 at two tertiary hospitals were described and evaluated using the Utstein style. We reviewed the records retrospectively and analyzed the outcome variables which were any return of spontaneous circulation (ROSC), sustained ROSC, survived event, and survival to hospital discharge. Neurologic outcome was assessed by the Pediatric Cerebral Performance Category (PCPC) scale. RESULTS: The study included 62 children with out-of-hospital cardiac arrest. Any ROSC was achieved in twenty patients (32.3%). Sustained ROSC of any ROSC group was achieved in sixteen patients (80.0%). Of the sustained ROSC group, fourteen patients (87.5%) were admitted to hospital, and only four patients (28.6%) of survived event group survived to hospital discharge. The prevalent etiology were injuries. Although 35 children (56.5%) of the arrests occurred at home with family members present, only 1 patients received bystander CPR. Nonshockable rhythm (96.8%) were showed more than shockable rhythm (3.2%). In any ROSC group, time to initiation of CPR was 9.3 minutes,duration of total CPR was 20.4 minutes. CONCLUSION: Mortality of pediatric out-of-hospital cardiac arrest was high and neurologic outcome was poor. Factors that increased survival rate were prevention of injuries, enhanced education programs of bystander CPR, rapid initiation of CPR.

Sudden unexpected death, in terms of absolute loss of life, poses our greatest single medical problem today. As our knowledge of the mechanisms of cardiac arrest continues to increase, it is encouraging to note how it can be applied to clinical situations. A good example is the well-documented story of succinylcholine-induced hyperkalemia and the propensity of patients with severe trauma and burns to develop cardiac arrest. There seems to be little question that an effective hospital cardiopulmonary resuscitation committee can contribute significantly to a reduction in mortality from sudden death within the hospital. Relatively low rates of successful resuscitation in hospital art partially due to a lack of realization of therapeutic requirements for specific situations. Broad generalizations are helpful for educational purposes, but the field of cardiac resuscitation has become sufficiently sophisticated to require in-depth knowledge of modifications in resuscitation efforts as individually required. Therefore, the authors attempted to evaluate the 40 cases of emergency calls for the anesthesiologists during the period of August 1975 to July 1976. Evaluated results were as follows; l. Incidence of emergency calls to the anesthesiologist was 24.4%(164 death vs 40 calls). 2. The method of emergency call was not efficiently established among the teaching hospitals yet. 3. None of the cardiopulmonary resuscitation committees was established and operating among the teaching hospitals now. 4. A cardiopulmonary resuscitation committee should be responsible for providing a written plan of action, CPR training and practice sessions, and a record of CPR occurences available for periodic audit and review.

BACKGROUND: The improved technique for cardiopulmonary resuscitation(CPR) has resulted in the survival of many patient who experienced cardiac arrest. However, mortality in resuscitated patients is high, and the survival rate without brain damage is very low. Various neurological examination models, neuro-imaging techniques, electrophysiological procedures, and biochemical tests have been studied with respect to the detection of cerebral damage and outcome, but an early, reliable prediction of individual outcomes is still uncertain. METHODS: We studied twenty patient who had been in a coma for more than 24 hours after CPR, Somatosensory evoked potentials(SEP) were measured within the first three days after CPR. RESULTS: Of the twenty patients, seven patients(35%) had a good outcome, and thirteen patients(65%) had a bad outcome. Of the eleven patients with loss of the cortical evoked potential's N20 peak, all had a bad outcome. CONCLUSION: SEPs are of great benefit in prognostic evaluation after CPR.

Pulmonary embolism is a common condition with considerable morbidity and mortality. The diagnosis of pulmonary embolism remains a vexing problem. Prompt and accurate diagnosis is important because the mortality of untreated pulmonary embolism is high and serious complications can occur. Most physicians are inexperienced in the use of thrombolytic agents fo r pulmonary embolism, even though they utilize these agents routinely for acute myocardial infarction. We compared 2 domestic cases with 2 foreign cases. On comparison, we spent a long time in making a definite diagnosis in the domestic cases. Moreover, in the second domestic case, we did not use thrombolytic agents early, in spite of a suspected massive pulmonary embolism and then eventually he died. We conclude that bolus administration of thrombolytic agents during CPR for clinically suspected massive pulmonary embolism in emergency departments may be an acceptable technique.

BACKGROUND: The use of uncrossmatched group O, Rh-negative RBCs has enabled immediate transfusion of patients who need critical care in life-threatening situations. We examined our 1-year experience with uncrossmatched group O, Rh-negative RBC transfusion in a tertiary care university hospital. METHODS: Uncrossmatched group O, Rh-negative RBCs were available for immediate transfusion upon request without performing any of the following pretransfusion tests: ABO and RhD typing, irregular antibody screening, crossmatching test. The characteristics of the transfused patients were studied retrospectively. RESULTS: Twenty-five patients received 56 units of uncrossmatched group O, Rh-negative RBCs from November 2005 to October 2006. An average of 2.24 units was issued to each patient, with no more than 4 units per patient being given; subsequent transfusion was done with type-specific, crossmatched blood. The average turnaround time for the release of uncrossmatched group O, Rh-negative RBCs was 1.8 minutes (mean+/-standard deviation: 1.8+/-1.96, range: 0~7 minutes). Seventeen patients died (68%), which included 16 patients who had received cardiopulmonary resuscitation. CONCLUSION: Patients admitted for traffic accident, falling down injury, gastrointestinal bleeding and aortic dissection received 72% of the emergency group O, Rh-negative RBCs, with a 72.2% mortality rate, which indicates the dire condition of these patients. The majority of RBCs for transfusion were available within 5 minutes upon request. Though group O, Rh-negative RBCs are recommended in emergency situations in which the blood group of the patient is unknown, the use of group O, Rh-positive RBCs may be an alternative blood supply, when considering the short supply of Rh-negative RBCs.

Anaphylactic reaction during the perioperative period typically exhibits rapid onset, varying clinical manifestations, and an expected mortality rate of 1.5-9%. Neuromuscular blocking agents are the leading cause of perioperative anaphylaxis. Here, we report a severe case of anaphylaxis that developed in a 66-year-old man due to cisatracurium administration. And he was successfully managed by extracorporeal membrane oxygenation. Cardiopulmonary resuscitation was performed by extracorporeal membrane oxygenation, and the patient was successfully weaned off 24 hours later.
