Evaluation of manually operated self-inflating resuscitation bags.

Eight resuscitators were tested, of which five have recently been improved by the manufacturers (Air Shields Ambu, Danish-made Ambu, Pulmonator, Laerdal Resusci II, and Air Viva). One had an addition made to improve its oxygen (O2)-delivering capacity (Hope bag fitted with Blount collar) and two were new, the Air Bird, with and without high O2-concentration delivering system. The first five resuscitators were all in some way an improvement over their earlier counterparts. However, some still malfunction, some do not deliver adequate O2 concentrations for hospital use, and there is still a great variability in their performance. In some, freezing at low temperatures or clogging of valves with mucus are special hazards.

Teflon injection of vocal cords under general anesthesia: a new method.

Use of general anesthesia permits the injection of Teflon paste into immobile vocal cords in an accurate and predictable manner, with the help of a special endotracheal tube and jetted O2 or O2/n2O mixture. The authors position a nonfunctioning vocal cord so that when the functioning cord is fully adducted , the two cords are in perfect approximation for phonation. This has allowed marked improvement in effective expulsive postoperative coughing and vocalization. Debris is blown away from the operating side and not into the patient's trachea. If excessive injection of Teflon is avoided, an uneventful postoperative course can be expected.

Dynamics of local-anesthetic compounds in regional anesthesia.

The clinical effectiveness and safety of compounded mixtures of lidocaine + bupivacaine and chloroprocaine + bupivacaine for either epidural or brachial-plexus block was studied in 48 adult patients. Of the several alternatives, chloroprocaine + bupivacaine with epinephrine was found the best choice for patients with typical plasma cholinesterase.

Further studies of manually operated self-inflating resuscitation bags.

Four resuscitators were tested, of which three had recently been improved by the manufacturers (Danish-made Ambu, Air Bird, Laerdal Resusci 2), and one was new (Hope 2). All functioned well at extremes of temperature and all would deliver 100 percent O2 to the patient. All are essentially vice-free and represent great steps forward in resuscitator design.
