[Left ventricular microcatheterization during acute myocardial infarction (author's transl)].

Left ventricular microcatheterization at the bedside was accomplished in 20 acutely ill patients with myocardial infarction. Direct measure of the left ventricular end-diastolic pressure shows that its values can substantially differ from those of the pulmonary artery end-diastolic pressure. The authors observed that left ventricular microcatheterization is indicated, in the course of acute myocardial infarction, in the following circumstances: --when either the pulmonary artery end-diastolic or the pulmonary capillary pressure is beyond normal limits; --in the presence of tachyarrhythmias which, for alteration of the dynamics of atrial contraction, increase the difference between the left ventricular and pulmonary artery end-diastolic pressures; --when a mitralic defect is associated with the acute myocardial infarction.

Neuropsychological outcome of survivors of out-of-hospital cardiac arrest.

Thirty patients resuscitated from out-of-hospital cardiac arrest (15 with and 15 without postanoxic coma on admission) underwent a clinical examination and neuropsychological testing. In order to assess quality of life, they were compared to two matched control groups; 15 patients with previous myocardial infarction and 15 healthy subjects. None of the survivors showed severe neurologic impairment, and all had returned to self-sufficient physical activity. However, the behavior rating scale scores were significantly worse in patients with postanoxic coma. The processing ability linked to memory was significantly worse in the postanoxic coma group. Mood disorders were also observed in this group, but they did not have pathological significance. The remarkably low incidence of neurologic and psychological sequelae in these resuscitated patients, particularly in those with early clinical evidence of severe cerebral damage, is an encouraging result that supports the therapeutic systems development and efforts in the management of out-of-hospital cardiac arrest.

Propafenone versus amiodarone in field treatment of primary atrial tachydysrhythmias.

Thirty-nine patients with paroxysmal atrial fibrillation or supraventricular tachycardia randomly received amiodarone or propafenone intravenously at home. Fifteen patients received amiodarone and 24 received propafenone; 87.5% of the patients who received propafenone and 40% of the patients who received amiodarone were converted at home to sinus rhythm (P less than .005). The median time of conversion was 10 minutes (range 5 to 35) for propafenone and 60 minutes (range 20 to 130) for amiodarone (P less than 0.005). When either drug failed to terminate atrial tachydysrhythmias at home, the same drug always restored sinus rhythm with subsequent oral treatment during hospitalization. No major side effects were observed after the infusion of either drug. The incidence of minor side effects was not significantly different between the two drugs. Both the drugs are efficacious and safe in the acute management of primary supraventricular tachydysrhythmias. Propafenone showed a greater rapidity of action.

Early out-of-hospital lidocaine administration decreases the incidence of primary ventricular fibrillation in acute myocardial infarction.

This study was designed to assess the effectiveness of early prehospital intravenous administration of lidocaine in preventing primary ventricular fibrillation (PVF) in patients with suspected acute myocardial infarction (AMI). Sixty patients with suspected AMI, seen by the Mobile Coronary Care Unit (MCCU) of Florence, were randomly allocated at home to treatment with lidocaine (bolus i.v. of 1 mg/kg, followed by an infusion of 4 mg/min) or placebo (infusion of saline at a rate of 1 mL/min), respectively. The lidocaine group (27 patients) and the control group (33 patients) were not significantly different in age, clinical condition, or time of randomization. The diagnosis of AMI was confirmed in all 60 patients during the hospital stay. Ventricular fibrillation (VF) occurred in 5 patients in the control group in comparison to none in the lidocaine group (P < 0.05). Three patients experienced VF at home and were successfully resuscitated by an MCCU cardiologist. In another two patients, VF occurred during the first 4 hours after onset of symptoms. No major side effects were observed after the infusion of lidocaine. Our findings support the effectiveness of the prophylactic administration of lidocaine in preventing PVF in the prehospital phase of AMI and suggest that the drug can be safely administered in this setting by prehospital personnel.

Paralytic ileus in a mechanically ventilated preterm infant treated with fentanyl.

The administration of fentanyl for sedation of ventilated newborns can induce several side-effects such as hypertension, respiratory muscle rigidity and, as shown in this report, decreased gastrointestinal motility. We report a case of paralytic ileus in a ventilated preterm infant who was given fentanyl in the first 24 hours of life. To our knowledge, the association of paralytic ileus with fentanyl has not been reported previously in full-term or preterm infants. This study indicates that early recognition is required to shorten the delay in diagnosis.

[External fixators in the treatment of fractures and fractures/luxations of the pelvis].

Combined fractures of the two pelvic arches and severe disjunction of the pubic symphysis are acute lesions which are difficult to treat; in order to avoid poor functional results, the use of external fixatives have now become a routine orthopedic surgical practice. Two cases are reported to illustrate the large numbers of patients treated by the Orthopedic and Traumatological Division of the Ospedale Civile in Alessandria.

[Review of 64 cases of hallux valgus surgically treated with the Keller-Lévière technique].

Sixty four cases of hallux valgus treated using the Keller-Lélièvre technique during the period from January 1982 to December 1987 are examined. The results achieved reveal the validity and limits of this surgical technique. Having established the prescriptions of the technique, it still represents the simplest and safest method for treating this affection in adult/old-aged patients.

[Our experience in the use of Thompson's endoprosthesis in medial fractures of the femur neck].

The study reports the results of a study of a random sample of 40 patients with medial fractures of the collum femoris in whom the caput femoris was substituted by Thompson's cemented prosthesis, taken from a series of 189 operations performed between 1981 and 1987. In conclusion, Thompson's prosthesis is demonstrated to be still valid in patients over 75 years old.

[A case of a fracture of the clavicle associated with an acromio-clavicular luxation].

The study reports a rate case of a girl with associated clavicular fracture and acromioclavicular dislocation following a care accident. The pathogenetic mechanism may be attributed to a trauma on the medial shoulder stump which having fractured the clavicle then provoked the acromioclavicular dislocation by continued pressure on that point. It is important to observe that the patient fully recovered, virtually without therapy.
