Therapeutic progress in intensive care--rational use of vasoactive and inotropic drugs in the intensive care unit.

Vasoactive (vasodilating and vasoconstricting) and inotropic drugs are widely used in intensive therapy. Major progress in their use in recent years has been due to a greater understanding of the physiological derangements of the critically ill. This progress is the consequence of improved standards of haemodynamic monitoring in the intensive therapy unit (ITU). In addition the introduction of accurate and reliable syringe pumps, to administer small volumes of fluid accurately, has enabled the easy use of drugs to manipulate physiological parameters. An understanding of the basic anatomy and physiology of the cardiovascular system (CVS) is essential to an understanding of the methods used for monitoring and measurement (1). Logical therapeutic interventions follow from consideration of these measured and derived parameters.

How to insert a Minitrach.

Minitracheotomy is a technique of cricothyroid cannulation to allow efficient tracheobronchial toilet and the application of other techniques for respiratory support. Indications and contraindications for the procedure are reviewed. Two methods of insertion are described with their potential difficulties. Possible complications and their treatment are considered.

Yersinia enterocolitica septicaemia.

Septicaemia from Yersinia enterocolitica carries a mortality of up to 80%. We report the successful management of a case who required intensive therapy, including inotropic and ventilatory support.

Evaluation of the comfort of spontaneous respiration through three ventilator systems.

The use of intermittent mandatory ventilation and continuous positive airways pressure systems is widespread. The comfort of spontaneous ventilation through three systems, with a variety of humidifiers, has been evaluated. The use of demand flow systems and the introduction of some humidifiers caused considerable discomfort from fluctuations in the airway pressure. It is concluded that continuous flow systems are preferable and that fluctuations in airway pressure should not exceed 2.5 cm H2O.

Minitracheotomy. A report of its use in intensive therapy.

Minitracheotomy is a simple percutaneous technique of tracheal cannulation using a small bore tube. It allows efficient tracheobronchial toilet while preserving glottic function. Examples of its use in the intensive therapy unit are described.

Minitracheostomy: a new delivery system for jet ventilation.

Seventeen patients with respiratory failure from a variety of causes have been treated by high-frequency jet ventilation, delivered by a specially designed Y connector and a standard minitracheostomy tube, for periods ranging from 12 hours to 14 days. This percutaneous system provides access for full ventilatory support and tracheobronchial suction, but without the need for a cuffed endotracheal tube or sedation. Patients can eat, drink, and talk during ventilation. Ten of the patients were male and ages ranged from 31 to 77 years. Ventilation was satisfactory in 16 patients and unsatisfactory in one, who had also been difficult to manage on conventional ventilation. Thirteen patients resumed full spontaneous respiration and four died of their underlying disease while still being supported with a ventilator. These results suggest that the combination of minitracheostomy and high-frequency jet ventilation may offer significant advantages in the management of some patients with respiratory failure.

Hereditary angioneurotic oedema.

Hereditary angioedema (HAE) is characterised by episodic swelling of the extremities, face, larynx and recurrent abdominal pain, which can mimic the acute abdomen. Trauma of the larynx may result in acute airway obstruction. The management of emergency anaesthesia for Caesarean section of a patient with documented HAE is described and the special problems presented discussed. The methods of prophylaxis available are considered and the use of fresh frozen plasma advocated.
