Case ReportsPostoperative delirium secondary to atropine premedication.
Anticholinergic agents used as preoperative medications have the ability to induce postanesthetic delirium reactions. We present a case of postanesthetic delirium secondary to premedication with atropine which was treated with intravenous physostigmine. This case is presented to alert the clinician to the possibility of this reaction occurring with the use of atropine, and to demonstrate the use of physostigmine in reversing postanesthetic delirium reactions caused by anticholinergics.

One century after the clinical introduction of cocaine, local anesthesia remains the most important method of pain control in dentistry. Many local anesthetics have been marketed since 1884, and it is likely that attempts to produce drugs that enhance anesthetic efficacy, reduce systemic and local toxicity, and increase nociceptive selectivity, will continue. ⋯ Of fundamental importance to such improvements are investigations into the pharmacology of drugs with local anesthetic activity and anatomical and physiologic studies pertaining to the reasons why local anesthetics sometimes fail to achieve desired results. This paper reviews recent advances in our understanding of these drugs and their clinical use.

Comparative StudyComparison of the effectiveness of etidocaine and lidocaine as local anesthetic agents during oral surgery.
In a double-blind study conducted in 112 patients undergoing removal of four impacted third molar teeth, etidocaine hydrochloride 1.5% solution with epinephrine 1:200,000 and lidocaine hydrochloride 2.0% solution with epinephrine 1:100,000 were used, one on each side of the face, to produce inferior alveolar nerve block, infiltration anesthesia of the maxillary tooth and hemostasis of the mucoperiosteum around each tooth. Surgically adequate anesthesia was rapidly produced by both agents but the duration of action of etidocaine was longer than that of lidocaine as reflected in more prolonged numbness of the lip and delayed onset of pain. Moreover, after etidocaine treatment fewer patients reported severe pain as the local anesthesia receded. No adverse local or systemic effects were observed in, or reported by, any of the patients.

Case ReportsEnflurane-induced grand mal seizures during otic microsurgery.
Abnormal electroencephalographic seizure-like activity and myoclonic movements have been recognized during enflurane anesthesia. This is most commonly seen in the presence of respiratory alkalosis and high concentrations of enflurane. ⋯ Experimental studies have shown that auditory stimuli could facilitate seizure activity during deep enflurane anesthesia. Here we report a case of intraoperative generalized tonic-clonic convulsion during low concentrations of enflurane without evidence of hyperventilation and the presence of auditory stimulation.
