Randomized Controlled Trial Comparative Study Clinical Trial
Neonatal acid-base status following general anesthesia for emergency abdominal delivery with halothane or isoflurane.
To determine whether halothane or isoflurane as anesthesia for emergency abdominal delivery is associated with better fetal acid-base parameters. ⋯ There is no difference in the frequency or severity of acidosis associated with isoflurane or halothane when used for general anesthesia for emergency abdominal delivery of a distressed fetus.

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.

Comparative Study
A comparison of propofol, midazolam, and methohexital for sedation during retrobulbar and peribulbar block.
To compare the efficacy of propofol, methohexital, and midazalom in providing adequate sedation during administration of retrobulbar block and satisfactory postoperative amnesia. ⋯ Grimacing or verbal response during the retrobulbar or peribulbar block did not predict or correlate with patient recall. Propofol was equal to both midazolam and methohexital in providing adequate sedation and postoperative amnesia but possesses the added advantages of reduced postoperative vomiting, lower intraocular pressure, and earlier return-to-home readiness.

Endoesophageal prostheses are sometimes used in palliative therapy of esophageal carcinoma. Placement or subsequent manipulation of these devices may require general anesthesia, and these anesthetics are fraught with potential complications, both from the patient's illness and from the prosthesis itself. The two patients in our report presented anesthetic challenges, including acute upper airway obstruction occurring outside the operating theater and management of malignant tracheoesophageal fistula.
