To determine the level of care available to obstetric patients during the immediate postanesthesia period. ⋯ In many obstetric PACUs, the level of expertise of personnel needs to be upgraded to ensure the safety of patients recovering from general or major regional anesthesia and to comply with existing care standards.

Brachial plexus blockade is a commonly used technique for providing surgical anesthesia for the upper extremity. Although various approaches have been described, the axillary approach is the safest and most frequently used. ⋯ A case of false aneurysm of the axillary artery following axillary nerve block is reported. The possible occurrence of this complication should be kept in mind to avoid permanent neurologic sequelae.

Clinical Trial
Accelerated recovery from doxacurium-induced neuromuscular blockade in patients receiving chronic anticonvulsant therapy.
To determine whether a drug interaction exists between doxacurium and anticonvulsants. ⋯ Chronic treatment with anticonvulsants results in more rapid recovery from neuromuscular blockade produced by doxacurium.
-
To determine the impact of a low fresh gas flow rate on the duration of carbon dioxide (CO2) absorption by soda lime. ⋯ Because soda lime color indicators are unreliable, when a semiclosed breathing circle is used at a low rate of fresh gas flow without CO2 monitoring, the CO2 absorbent must be replaced more frequently.

Comparative Study
Pharmacokinetics and effects of 9-amino-1,2,3,4-tetrahydroacridine in the immediate postoperative period in neurosurgical patients.
To determine the effects of intravenous (IV) 9-amino-1,2,3,4-tetrahydroacridine (THA) on postoperative somnolence in comparison to its pharmacokinetics. ⋯ The duration of the effects of THA as an antagonist of postoperative sedation was only about double that seen previously after the IV administration of physostigmine in a similar group of patients, although the elimination half-life of THA was six times longer than that of physostigmine. A larger dose of THA possibly could have been given to prolong the period of antagonism of sedation, but the profile of adverse effects seen even at the doses used precluded that option.
