Resuscitation

A tremendous amount of public resources are focused on improving cardiac arrest (OHCA) survival in public places, yet most OHCAs occur in private residences. ⋯ Many important characteristics of cardiac arrest patients and the bystander differ in public versus private locations. Fundamentally different strategies are needed to improve survival from these events.

To assess which items of resuscitation equipment are carried on United Kingdom (UK) front line ambulances and what procedures paramedics are able to perform. To compare these findings with those of a previous survey in 1997. ⋯ The equipment available to UK paramedics and procedures that they may perform continues to expand. There are still variations in the basic management of airway, breathing and circulation care and only some services are keeping up to date with current medical thinking, for example the increasing use of crystalloids and hypotensive resuscitation. It remains to be seen whether the widespread use of Nalbuphine as a first line analgesic may decrease as the use of natural strong opiates becomes more widespread.

Several reports demonstrate non-specific hyperamylasemia in cardiac surgery or diabetic ketoacidosis. We report here for the first time non-specific hyperamylasemia in a cardiovascular beri-beri case who showed shock with severe metabolic acidosis. Her echocardiography revealed hyperkinetic wall motion of the small left ventricle. ⋯ Thiamine administration dramatically reversed her haemodynamic derangements, metabolic acidosis and even relieved her abdominal pain. Isozyme examinations for hyperamylasemia showed that most of the serum amylase consisted of salivary type. This case report expands our information on non-specific hyperamylasemia encountered in the emergency setting.

The PA(xpress) phayngeal airway (PA(x)) is a new single use airway device that might be used for airway maintenance during anaesthesia or cardiopulmonary resuscitation. We evaluated the performance of the PA(x) in 103 anaesthetised non-paralysed patients undergoing non-emergency anaesthesia. We recorded success of insertion, quality of airway achieved and complications of its use. ⋯ Complications occurred in 38 (37%) patients during insertion, in a further 12 (13%) during maintenance and in eight (9%) during emergence. The device was difficult to insert and associated with a high incidence of trauma: blood was visible on the device after removal in 56 (55%) cases. We conclude that the PA(x) is associated with too high a failure rate and too high an incidence of minor complications for routine airway maintenance.

Comparative Study
Effect of amiodarone on haemodynamics during cardiopulmonary resuscitation in a canine model of resistant ventricular fibrillation.
Amiodarone has been shown to be superior to both placebo and lidocaine in improving survival to hospital admission for victims of out-of-hospital refractory ventricular fibrillation. Concern had been expressed about the known vasodilatatory effects of amiodarone if given without precedent vasoconstrictive medications. The haemodynamic effects of intravenous amiodarone administered during ongoing CPR have not been systemically investigated. Our intention was to verify if amiodarone alone produced significantly lower resuscitation haemodynamics than did either adrenaline (epinephrine) alone or the combination of amiodarone and adrenaline. ⋯ Amiodarone can be safely administered simultaneously in combination with adrenaline and such a combination results in similar haemodynamic support as adrenaline alone. Amiodarone administered alone produces significantly lower coronary perfusion pressure than when combined with adrenaline.
