Historical Article[The introduction of chloroform anesthesia in Madrid. Notes for studying its history].
Until present, the introduction of chloroform anesthesia in Madrid has not been specifically studied by any author. Therefore, knowledge of the events related to this happening is lacking. We have studied this chapter of our history by analyzing primary documents and articles published at the daily press, political press, and scientific journals of Madrid during 1847 to 1848. ⋯ Based on the present bibliographic material we could establish a chronologic report of all surgical interventions using chloroform that were performed in Madrid. We conclude that albeit surgeons in Madrid were not the first to use chloroform in Spain, they were, however, the ones who most extensively used it. Their contribution was of relevance in the settlement of the new anesthetic agent in Spain.

A 20-yr-old primigravida at 38 weeks gestation with premature rupture of membranes and evidence of fetal distress required urgent Caesarean section. The diagnosis of osteogenesis imperfecta had been made 4 days earlier. ⋯ Difficulties in the administration of general anaesthesia to patients with osteogenesis imperfecta were recognized and managed accordingly. These problems are discussed and the importance of early antenatal assessment of such patients by the department of anaesthesia is emphasized.

Comparative Study
Mivacurium infusion during nitrous oxide-isoflurane anesthesia: a comparison with nitrous oxide-opioid anesthesia.
To determine the potentiation of the neuromuscular blockade induced by a titrated infusion of mivacurium in the presence of isoflurane versus a nitrous oxide (N2O)-opioid anesthesia. ⋯ Isoflurane anesthesia reduces the infusion rate of mivacurium required to produce about 95% depression of neuromuscular function.

Randomized Controlled Trial Clinical Trial
Flow increases with an enlarging intravenous catheter.
To determine the increase in flow of a hydratable enlarging intravenous (IV) catheter in anesthetized patients. ⋯ Flow through enlarging IV catheters placed in anesthetized patients increases after 1 hour. The percentage increase in flow is not as great as previously seen in vitro and may be due to skin, vein, and subcutaneous tissues preventing complete expansion.

Randomized Controlled Trial Comparative Study Clinical Trial
A haemodynamic comparison of epidural versus intrathecal sufentanil to supplement general anaesthesia for abdominal aortic surgery.
The present study was designed to evaluate the influence of epidural sufentanil (ES) and intrathecal sufentanil (IS) on the peri-operative haemodynamic responses during abdominal aortic surgery. Twenty-four ASA Grade II patients without clinical symptoms of coronary artery disease received, randomly, epidural (n = 12) or intrathecal (n = 12) sufentanil combined with light general anaesthesia for elective bifemoral grafting for aorto-iliac occlusive disease. The IS group contained significantly more hypertensive patients than the ES group. ⋯ Revascularization produced significant differences in HR, SVR and CI in both groups in comparison with the pre-declamping period. Notable was the maintenance of systemic blood pressure following revascularization due to preservation of sympathetic activity. It was concluded that both epidural and intrathecal sufentanil produce comparable and stable haemodynamics in this category of patients.
