Postoperative neuroleptic malignant syndrome. A case report.

A case of postoperative neuroleptic malignant syndrome is presented. A healthy 23-year-old male underwent a shoulder repair under uneventful fentanyl, halothane, nitrous oxide and oxygen anaesthesia. He received droperidol 5 mg IV and metoclopramide 10 mg IV intraoperatively to prevent postoperative nausea. Postoperatively, the patient developed autonomic instability, fever and generalized muscle rigidity. His level of consciousness was depressed. These findings were consistent with the diagnosis of neuroleptic malignant syndrome. The supportive treatment of the patient included active cooling measures, muscle relaxation and mechanical ventilation. The ability of anti-dopaminergic agents, including metoclopramide and droperidol, to precipitate the neuroleptic malignant syndrome is discussed. Treatment of the neuroleptic malignant syndrome is briefly discussed.

Appraisal of pediatric cardiopulmonary resuscitation.

Sixty-six patients more than 30 days and less thant 16 years of age suffering an unexpected cardiac arrest in an 18-month period were included in a study of resuscitative measures in children. Six children survived to be discharged from hospital. Respiratory disease accounted for most (29%) of the cardiac arrests, but it also had the most favourable prognosis, 21% of the 19 patients surviving. None of the patients survived whose cardiac arrest was secondary to sepsis or trauma, even when the resuscitative efforts were initially successful. Only 1 of the 41 patients who had a cardiac arrest outside of hospital survived, and only 1 of the 34 patients who presented with asystole survived, and then with considerable damage to the central nervous system. The interval between cardiac arrest and application of basic life support was substantially shorter among the survivors. Also, most of the survivors did not present with asystole. The results of this study suggest that survival among resuscitated children is no better than that among adults but can be improved with early recognition and monitoring of children at risk. earlier application of basic and advanced life support, improved education of medical and lay personnel, and further research into pediatric resuscitative techniques.

Resuscitation from cardiac arrest: assessment of a system providing only basic life support outside of hospital.

Resuscitation outside of hospital of victims of cardiac arrest is a major challenge to our emergency care system. Most cities in Canada do not have a mobile advanced life support service; instead they rely on basic life support outside of hospital. The outcome in such cases and the factors affecting the outcome are largely unknown. Thus, it is difficult to estimate the lifesaving potential of adding advanced life support to the existing measures available for care outside of hospital.A prospective study of all resuscitation attempts begun outside of hospital was conducted during 18 consecutive months in 1977-78 in Winnipeg; at that time only basic life support was available outside of hospital. Resuscitation was attempted 849 times, and 33 patients (4%) survived to be discharged from hospital. Data analysis revealed that: (a) none of the 58% of patients in asystole at the time of arrival at a hospital survived to be discharged, but 11% of the patients with ventricular fibrillation or tachycardia (27% of the entire group) survived; (b) the survival rate was lower when the interval from the emergency telephone call to the patient's arrival at the hospital exceeded 10 minutes; and (c) basic life support was begun immediately in 29% of the patients with ventricular fibrillation or tachycardia, and increased the survival rate fivefold.The training of private citizens in basic life support is a vital component of total emergency cardiac care. A mobile advanced life support service will be effective in saving lives if it reduces the delay before definitive care is instituted, preferably to less than 10 minutes.

Evaluation of hospital-based cardiac resuscitation, 1973--77.

The resuscitation experience of a large teaching hospital during 1973-77 was reviewed. Resuscitation was attempted on 2091 victims of cardiac arrest; 261 patients (12.5%) survived to be discharged from hospital.Coronary heart disease caused about one half of all the cardiac arrests, but was associated with a better survival rate (14.4%) than the other causes. Cardiac arrest following multiple trauma had the worst prognosis; only 3% of the patients survived to be discharged from hospital. However, the main factor influencing outcome was the site of arrest. The survival rates of patients on whom resuscitation was initiated in the emergency room or an intensive care area were triple and double the rate for patients in hospital wards, although one third of all the cardiac arrests induced by a coronary event and occurring in hospital were on the wards. Patients whose arrest occurred outside hospital, where only basic life support was available, had a survival rate of just 6.3%, whereas those whose arrest occurred in the emergency room had a survival rate of 31.9%. Since these two patient groups were similar in terms of age and diagnosis, we believe that the potential survival rate for victims of cardiac arrest outside of hospital that are optimally treated is close to 30%.These data suggest that increased survival from cardiac arrest can be expected with extension of the resuscitation services both inside and outside of hospital, but particularly with increased emphasis on emergency cardiac care outside of hospital.

Resuscitation from cardiopulmonary arrest during accidental hypothermia due to exhaustion and exposure.

A 16-year-old boy with accidental hypothermia and cardiopulmonary arrest due to exhaustion and exposure was resuscitated after warming measures -- hot wet towels, hot water bottles, and hot water enemas and gastric lavage -- had increased his rectal temperature from 25.2 to 28.0 degrees C. Despite prolonged cardiopulmonary arrest, recovery was almost complete, with no evident cerebral damage. Cardiopulmonary resuscitation procedures should not be abandoned until the body temperature is more than 30 degrees C, because the prognosis in cases of accidental hypothermia without associated disease is excellent if cardiac function can be re-established.
