Case ReportsDisseminated intravascular coagulopathy diagnosed by computed tomography.
A 24-year-old man was brought to casualty after a fall. He suffered from head injury and multiple fractures. On arrival he was apneic and the heart was at a standstill. ⋯ Asystole followed and resuscitation was unsuccessful. Postmortem CT scanning of the chest revealed that the tracheobronchial tree was flooded with blood and coagulation profile showed the picture of disseminated intravascular coagulopathy. CT may be useful in the diagnosis of some pathological conditions when autopsy is difficult to perform.

Comparative StudyNeuromuscular and cardiovascular effects of mivacurium chloride (BW B109OU) during nitrous oxide-narcotic, nitrous oxide-halothane and nitrous oxide-isoflurane anesthesia in surgical patients.
One hundred seventeen adult surgical patients were studied to compare neuromuscular and cardiovascular effects of mivacurium chloride during nitrous oxide-narcotic (BAL, n = 45) nitrous oxide-halothane (HAL, n = 27) and nitrous oxide-isoflurane (ISF, n = 45) anesthesia. Anesthesia was maintained with nitrous oxide (60%-70%) and oxygen (30%-40%) with end-tidal concentrations of halothane or isoflurane to yield a total MAC of approximately 1.25, or with supplemental fentanyl and thiopental as clinically indicated. Twitch response of the adductor pollicis muscle was elicited by supramaximal square wave pulses of 0.2 msec duration at a frequency of 0.15 Hz (Grass S44 stimulator) to the ulnar nerve and quantitated by a Grass FT10 transducer. ⋯ For the 0.05 mg/kg dose, maximum block was greater in the ISF group (89.1 +/- 2.7%, n = 9) than in the HAL (70.3 +/- 7.6%, n = 9) or BAL (67.7 +/- 6.4%, n = 9) groups. At higher doses of mivacurium, isoflurane produces a greater potentiation of neuromuscular block than halothane or balanced anesthesia. There were no significant cardiovascular changes seen in any group following mivacurium doses up to 0.15 mg/kg (approximately 2xED95).

Clinical TrialDysrhythmias during oral surgery--effect of combined local and general anesthesia.
In two groups, each of 50 patients undergoing pulpectomy or multiple extractions, effects of combining xylocaine nerve block with halothane general anesthesia were studied. Local blockade of surgical stimuli reduced markedly the incidence of dysrhythmias occurring during halothane anesthesia. Recovery was faster and postoperative analgesia was enhanced.
